Lograr el mejoramiento de la productividad en las operaciones de las Pymes mediante el uso de metodologías que los soporten es el desafío que tienen los líderes empresariales, por esta razón se emprende una investigación para identificar los estudios que han sido abordados sobre el Lean Six Sigma (LSS) y la Industria 4.0 (I4.0) en las pequeñas y medianas empresas manufactureras (Pymes) publicados entre los años 2005 y 2020 en idioma inglés, como un insumo preliminar para el desarrollo de futuros trabajos investigativos en el área.
Este artículo busca determinar, con base en una revisión de la literatura científica, cuáles son las tendencias, países, autores y factores metodológicos de mayor y menor participación, a través del análisis del LSS, la I4.0 y las Pymes de modo que se identifiquen futuras oportunidades de investigación.
Para el desarrollo del estudio se hace una revisión sistemática de la literatura (RSL), la cual orienta la formulación de las preguntas de investigación, la definición de los criterios de búsqueda, la definición de criterios de inclusión y exclusión, la evaluación de la calidad de los artículos y la identificación de oportunidades de investigación. Para complementar el trabajo se realiza un análisis taxonómico de la literatura, con el objetivo de caracterizar y ponderar elementos de la revisión sistemática que permitan identificar factores metodológicos clave para establecer investigaciones futuras.
Después de hacer la búsqueda a través de la RSL se seleccionan 105 artículos, donde se logró identificar el porcentaje de participación de los mismos en las agrupaciones temáticas estudiadas: 58% de los artículos hallados están relacionados con el LSS-Pymes, seguidos de 29% de artículos relacionados con la I4.0-Pymes; con 12% están el LSS-I4.0 y, finalmente, Pymes-LSS-I4.0 con 1%. Derivado del análisis se identifica que las temáticas estudiadas tienen interés creciente en la comunidad científica de acuerdo con el comportamiento evidenciado en las publicaciones entre 2005 y 2020. Además, se identifican los autores y países representativos en las temáticas LSS-Pymes y I4.0-Pymes, destacándose autores como Jiju Antony y Erwin Rauch y países como Reino Unido, India, Italia, Estados Unidos y Alemania. También se identifica que las metodologías que integran las temáticas de estudio simultáneo de las Pymes, LSS e I4.0 son pertinentes pero han sido poco exploradas, convirtiéndose así estas en una oportunidad de investigación que debe ser abordada para ampliar la frontera de conocimiento en esta temática.

El cáncer colorrectal (CCR) es uno de los más frecuentes a nivel mundial. Aproximadamente un tercio de los casos se originan por la vía serrada de carcinogénesis, siendo las lesiones serradas sésiles (LSS) de colon, una las principales responsables del CCR de intervalo. Objetivo: Evaluar las características clínicas, endoscópicas, histológicas y el manejo endoscópico de las LSS de colon. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo de julio del 2017 a junio del 2019 en el servicio de gastroenterología del Hospital Nacional Guillermo Almenara Irigoyen, Lima – Perú. Se evaluó las características de 79 LSS, se utilizó el estadístico chi-cuadrado para analizar la asociación de variables clínicas y endoscópicas con la presencia de displasia; y el tamaño de la lesión con el tipo de resección endoscópica. Resultados: En 74 pacientes se halló 79 LSS, 67 (84,8%) con displasia (44 de alto grado y 23 de bajo grado). Edad media de 52 años y 44 (59,4%) fueron varones. La localización en colon derecho (OR=5,09, IC 95% 1,38–18,7, p= 0,009), el tamaño >10 mm (OR=6,13/IC 95%/1,50–24,94/ p=0,014) y los “bordes borrosos” (OR=5,08, IC 95% 1,17-21,98, p=0,019), se relacionan de manera significativa con la presencia de displasia. Las LSS menores a 20 mm mostraron asociación estadística con la resección en bloque (OR=69,3, IC 95% 7,35-653,9, p<0,001) respecto a la piecemeal. Conclusiones: El hallazgo de LSS durante colonoscopías es frecuente. La año y el hallazgo de bordes borrosos se relacionan con la presencia de displasia. La resección endoscópica ucosa fue una técnica segura y efectiva.

PurposeLean Six Sigma (LSS) has been one of the most widely used quality improvement initiatives over the last decade. However, the success rate of LSS is dismally poor, and most organizations discontinue LSS initiatives prematurely. The purpose of this paper is to answer the question why do organizations discontinue LSS initiatives?Design/methodology/approachTo understand the discontinuance mechanism of LSS initiatives, the authors selected two companies. One from the manufacturing and one from service sector in India. The companies were selected as they had initially implemented LSS, and later within six years had discontinued the initiatives. Four projects from each company were studied using case study methodology.FindingsThis study finds 11 factors due to which the organizations discontinue LSS initiatives. The factors are poor success rate, unrealistic expectations from LSS, unsustainable results, misuse of statistics, large tool set, unsupportive and uncommitted top management, lack of training and development, lack of synergy of LSS and business strategy, lack of link between LSS and customer needs, wrong projects selection and premature discontinuation of LSS experts. The study further discusses the discontinuance mechanisms of LSS using propositions.Practical implicationsLSS is one of the most widely used initiatives in the organizations. Such initiatives involve costs. Earlier studies have reported that many organizations discontinue the LSS initiatives resulting in a loss or not meeting the intended goals. This paper will help the practitioners as well as organizations to understand why organizations discontinue LSS and take prompt actions for its success.Originality/valueEarlier studies on LSS address the critical success factors, and this paper addresses those about failures by studying organizations that have discontinued LSS. The present study finds 11 factors that are responsible for discontinuing LSS in organizations. In addition, propositions are developed for future research and empirical testing. This study also offers further insights into the discontinuance mechanisms involved in LSS.

Purpose Historically, Lean Six Sigma (LSS) implementation has demonstrated a great deal of enhancement to process efficiency, profitability and customer satisfaction. The emerging market pressure for developing better quality, cheaper and greener products invokes a change of view in LSS economical effectiveness. The purpose of this study is to identify under which condition the final output of LSS projects with traditional strategic benefits are more environmentally friendly. Design/methodology/approach To investigate the choice of different types of LSS projects, the environmental impact under different conditions and the comparison of those conditions, the author developed an analytical mathematical model and analysed four different propositions. Findings The final price and production volume were recommended as mediating factors to leverage an LSS project to achieve a greener, customised and finance-oriented outputs. Research limitations/implications This research contributes to existing LSS research and knowledge development via promoting the different perspectives of LSS and environmental sustainability integration. Practical implications This study further enables managers to identify the cut-off point in relation to the production volume and finished prices to leverage the expected financial outputs and environmental impact of the LSS project. This would potentially promote a green LSS project in both implementation and output, alongside its traditional values. Originality/value This study uses a modelling approach to identify the conditions under which the actual methodology of the LSS project could be green via less energy consumption with consideration of expected LSS values and outcomes.

Purpose Although the popularity of the Lean Six Sigma (LSS) methodology has illustrated many benefits over the years for those organisations who have implemented it, this strategy has received less attention in developing countries. The purpose of this paper is to critically assess the current status of LSS implementation in Saudi Arabian organisations. Design/methodology/approach This research is based on a descriptive survey questionnaire which has been derived from two systematic literature reviews. The survey was distributed to 400 organisations in Saudi Arabia using Qualtrics online software. In total, 146 responses were received where 102 responses were completed and analysed. Findings The findings of the survey highlighted that the implementation of LSS is still in the early stages in organisations within Saudi Arabia. This was clearly shown by many factors such as years of deploying LSS, LSS infrastructure, level of awareness of LSS, impact of LSS on business functions and so on. Research limitations/implications The primary limitation of this study is that data has been collected from an online survey and therefore no deeper insights could have been captured from the survey. This calls for future research to be undertaken by executing semi-structured interviews in selective organisations within Saudi Arabia. Originality/value This paper contributes to the current status of LSS in Saudi Arabian organisations. It also gives recommendations to guide the future of LSS in Saudi organisations by comparing LSS literature with best practice.

This study aimed to describe the relationships between leisure boredom, leisure satisfaction, and smartphone addictions among university students. The study sample consisted of 258 participants, 143 males and 115 females, studying at Istanbul University-Cerrahpaşa Faculty of Sports Sciences. The participants were selected using the purposeful sampling method. Data collection tools involved a personal information form, the "Leisure Boredom Scale (LBS)", the "Leisure Satisfaction Scale (LSS)" and "Smartphone Addiction Scale-Short Version (SAS-SV)". Independent t-Test results revealed a significant difference in SAS-SV by gender. The MANOVA results indicated a significant difference between the "Satisfaction" sub-dimension of LBS and the "Educational," "Social," "Physical," and "Relaxation" sub-dimensions of LSS by gender. A significant difference was found between LBS's "Satisfaction" sub-dimension and all sub-dimensions of LSS by income status. According to the ANOVA results, there was no significant relationship between the SAS-SV scores by income status of the participants. Besides, there was a negative and low-level correlation between age and the "Satisfaction" sub-dimension of LBS, the "Physical" and "Relaxation" sub-dimensions of LSS and SAS-SV. There was a negative and low correlation between "Boredom" of LBS and "Psychological," "Social," and "Relaxation" sub-dimensions of LSS, and there was a positive and low correlation between LBS and SAS-SV. Similarly, a positive and low-level relationship was determined between all sub-dimensions of LSS and SAS-SV. In this sense, it was concluded that the LBS, LSS, and SAS-SV scores differed according to the socio-demographic characteristics of the participants. As leisure boredom increased, leisure satisfaction decreased, and smartphone addiction increased. It was also found that as leisure satisfaction improved, smartphone addiction increased.

Purpose – Literature reviews in the field of Lean Six Sigma (LSS) are often substantially less stringently portrayed than other empirical research. The purpose of this paper is to lucubrate on clarifying emerging aspects, trends and importance of LSS through reviewing the published literature over multiple parameters for a ameliorating and trenchant view. Design/methodology/approach – In the present study, a literature review of LSS articles is carried out over the time horizon of 14 years from referred peer-reviewed journals in business and management disciplines, information systems and computer science, engineering, healthcare, etc. While carrying out the literature review, various distinct dimensions are considered, such as publication years and journals, countries, research design, research type and application sector within industries. A descriptive evaluation of the literature body is followed by gap identification and future research opportunities. Findings – LSS research is growing rapidly, covering various disciplines and domains with a great focus on LSS tools and techniques; empirical research is dominant with more emphasis on case study approach; and growing gap between manufacturing- and service-focused articles implies return of LSS to manufacturing as its initial base. Originality/value – The review analysis entirely focuses on descriptive statistics of empirical research in LSS. The sample size includes 189 shortlisted articles in 58 journals published over a time span of 14 years (2001-2014). The paper provides both academicians and practitioners a better panorama to understand the present status of LSS for pursuing rigorous LSS research through explicating chronological emergence, challenging themes, dominating research types and application areas in LSS.

Purpose We aimed to determine the prevalence of left ventricular systolic dysfunction (LVSD), including symptomatic (ie, heart failure [HF]) and asymptomatic LVSD in adult lymphoma survivors (LSs) after autologous hematopoietic stem-cell transplantation (auto-HCT) and to identify risk factors for LVSD in this population. Patients and Methods All LSs treated with auto-HCT as adults in Norway from 1987 to 2008 were eligible for this national cross-sectional study. Asymptomatic LVSD was defined as left ventricular ejection fraction less than 50% by echocardiography, and HF was defined according to current recommendations. The results in LSs were compared with those found in an age- and sex-matched (1:1) control group. Results We examined 274 LSs (69% of all eligible survivors); 62% were men, the mean (± standard deviation) age was 56 ± 12 years, and mean follow-up time from lymphoma diagnosis was 13 ± 6 years. The mean cumulative doxorubicin dose was 316 ± 111 mg/m2, and 35% of LSs had received additional radiation therapy involving the heart. We found LVSD in 15.7% of the LSs, of whom 5.1% were asymptomatic. HF patients were symptomatically mildly affected, with 8.8% of all LSs classified as New York Heart Association class II, whereas more severe HF was rare (1.8%). Compared with controls, LSs had a substantially increased LVSD risk (odds ratio, 6.6; 95% CI, 2.5 to 17.6; P < .001). A doxorubicin dose ≥ 300 mg/m2 and cardiac radiation therapy dose greater than 30 Gy were independent risk factors for LVSD. Conclusion LVSD was frequent and HF more prevalent than previously reported in LSs after auto-HCT. Our results may help to identify LSs at increased LVSD risk and can serve as a basis for targeted surveillance strategies.

We have made a preliminary comprehensive cost estimation for reliability of life support systems (LSS) in 1000-d remote space exploration missions with the loss-of-crew probability at 0.0001 due to failure of hybrid, partly and maximally closed-loop LSSs currently used onboard the ISS Russian segment. Comprehensive cost of a simplified test program is 5-times higher than cost of any LSS. A beta-factor parametric model was used to analyze LSS reliability against common cause failures (CCFs) when reiterative redundancy cannot provide superhigh reliability. It appears that the required reliability against CCFs is achievable on the diversification principle, i.e. reiterative diverse redundancy of basic LSS technologies. The estimated LSS cost is twice as much in comparison with the traditional approach that takes into account independent failures only. Diverse inherent cold redundancy can reduce the cost about 30 % provided that R&D expenses on regenerative subsystems are equal.

Six sigma is valuable to process control and ensure the stability of product quality. Lean practices or six sigma in isolation cannot remove all types of waste, control the process statistically, and remove process variability. The integrated development of the two approaches, which are known as Lean and six sigma (LSS), may bring out the advantages of both concepts. Although, many enterprises have succeeded with LSS around the world only less than 20% of enterprises achieve and maintain lean activities for the time being. The aim of this research paper is to present the key factors that constitute a successful implementation of LSS in the wood industry in Vietnam through analysis of LSS implementation. A combination of a comprehensive literature review and a site visit to deeply observe by participants observation for 3 LSS projects and interview the key persons involved in the project was employed in this study.

Background: Lumbar spinal stenosis (LSS) is one of the important health problems in an aging society because it can significantly impair quality of life (QOL) and active daily living (ADL). However, the natural history or long-term change of LSS symptoms is still unclear. The purpose of this study was to clarify the 10-year course of lumbar spinal stenosis (LSS) symptoms in community-dwelling residents of more than 1000 people with prospective data collection. Methods: A total of 1149 subjects were analyzed for the time course of LSS symptoms for ten years. LSS symptoms were assessed using a questionnaire specially designed and validated to detect LSS symptoms without image information such as magnetic resonance imaging. Results: The prevalence of positive LSS symptoms was about 16% in the initial survey and 10-year follow-up. Of the subjects who were LSS positive at the initial survey, 40% showed positive LSS symptoms at follow-up and 60% switched to negative LSS symptoms. According to the multivariable logistic regression analysis, severe depression and positive LSS symptoms were extracted as predictors of the presence of LSS symptoms after a 10-year follow-up. Conclusion: The statistical predictor of the presence of LSS symptoms at 10 years was the presence of LSS symptoms at the initial survey; however, 60% of those who were positive for LSS symptoms at the initial survey were not determined to have LSS symptoms at the 10-year follow-up. This was the same result as at the 1-year and 6-year follow-up.

Purpose The purpose of this paper is to examine a contextualized local government case study of the application of Lean Six Sigma (LSS) in conjunction with the Australian Business Excellence Framework (ABEF) to highlight the importance of a good strategic fit between LSS and organizational objectives before implementation. Design/methodology/approach A local government council is used in a case study-based approach. Organizational artefacts and documents were used for data collection in conjunction with interviews from senior executives within the organization. Findings Results indicate that when used in conjunction with the ABEF, LSS provides focus on organizational learning practices embedded within the implementation of continuous improvement. Research limitations/implications The purpose of this paper is to contribute to discourse regarding the effective application and implementation of LLS in local government. Practical implications LSS tools and techniques are known to local government, but are applied in isolation of the overarching LSS framework. This paper emphasizes the importance of comprehensive implementation of these tools, guided by the inclusion of an external contextualized framework (ABEF) in conjunction with the LSS to achieve sustainable continuous improvement. Originality/value Business excellence frameworks are widely used in the public sector as a reference/means for improvement. This paper highlights the importance of LSS in operationalizing strategic direction provided by such frameworks and providing the focus on learning practices critical for sustainable improvements.

Purpose The purpose of this paper is to present the potent application of Lean Six Sigma (LSS) in higher education services and to suggest a conceptual framework of deploying LSS in the higher education institutions (HEIs). Design/methodology/approach This paper aims to outline the importance of the quality excellence criterion in general through different constructs from the literature including TQM, Lean, Six Sigma and LSS. The paper further expands on the applicability of LSS in the HEI setting, with an understanding of HEI as comparatively different from the manufacturing sector from where LSS originated. The published literature on LSS and authors’ experience in the field of LSS (as practitioners) were used as sources for devising a conceptual framework for LSS deployment in HEIs. Findings The key finding from the study is the confirmation of LSS applicability in HEIs. The study also confirms that LSS is not anyone’s job but a key part of leadership agenda. The six-staged conceptual framework prescribed for the HEIs as part of the paper is the key contribution of this study. The model describes that LSS readiness is the foremost step in the LSS deployment journey in HEIs. The strategic perspectives of aligning the organisational vision for quality excellence need to be achieved by establishing a need for LSS through leadership. Then, developing an LSS deployment strategy becomes the next step. Educating the appropriate stakeholders (students) and team formation becomes the next important steps in the LSS deployment. Once the above steps are implemented in right way, identifying and implementing LSS projects becomes critical. The execution and closure of the LSS projects leads to quality excellence in HEIs. Research limitations/implications Since the framework prescribed here is a conceptual framework, it deserved a testing in the real-life context. This leaves an opportunity for future researchers to test and expand on the implications of the model. Though the LSS framework is customised for HEIs, the fundamental factors essential for any change management initiative holds correct for LSS as well, and hence these are not elaborated as part of this paper. Originality/value This paper would serve as an excellent resource for both academicians and LSS practitioners in HEIs, for deployment. The framework presented here is the original work contributed by the authors, as the first of its kind in the academic literature relevant to LSS in HEIs.

Maternal morbidity and mortality associated with pregnancy and childbirth have a significant impact on women, their families, and communities in low-income countries. This study aimed at exploring the level of awareness on Life-Saving Skills (LSS), LSS practices employed, barriers to implementation, and strategies to promote effectiveness of LSS practice. The study utilized a cross-sectional research design and a pre-tested structured interviewer-administered questionnaire to survey 154 nurses and midwives in a hospital in Nigeria with 150 maternity beds, about their “awareness” of LSS, LSS practices, and what they consider barriers to implementation and strategies to promote effectiveness of LSS practice. Results demonstrated that while 87.0% of the respondents were aware of LSS, the majority reported numerous challenges in implementing LSS. These challenges included: a shortage of skilled birth attendants (93.5%); negative attitudes of healthcare providers (79.2%); inadequate equipment and supplies (81.8%); and inadequate training for midwives (77.9%). Respondents also recommended some strategies to promote effectiveness of LSS, including provision of life-saving skills equipment (84.4%); training and retraining of personnel in LSS (88.3%); and increasing accessibility of LSS services for childbearing women (97.4%). The study concluded that although there is a high level of awareness of LSS, the midwives and nurses faced many challenges that hindered the utilization of LSS. It is recommended that multilateral collaboration be used in the study setting to overcome the limitations to utilize LSS.

Purpose The purpose of this paper is to compare the impact of lean six sigma (LSS) implementation carried out in a pharmaceutical unit on the profitability of outpatient and inpatient care before and during the Covid-19 pandemic. Design/method/approach The data were analyzed descriptively to see the development patterns in four periods: before implementation, during the implementation before the pandemic, during the pandemic and during the enforcement of new normal, in general, and by the length of stay (LOS). Findings The inventory purchase in the pharmaceutical unit dramatically decreased after implementation even during the pandemic and new normal wherein the pre-pandemic it decreased by 27%, during the pandemic 29% and in the new normal 37% compared to pre-LSS. The hospital deficit decreased after implementation before the pandemic by 26% and during the pandemic by 10% from the pre-LSS time. However, during the new normal, the deficit increased by 29%, indicating a diminished effect of LSS on the hospital profits. Research limitations/implications This research raised the possible implication that the implementation of LSS needed to be carried out in the entire hospital to have a large effect, especially on the inpatient care and long-term care installations. Originality/value This research provided empirical evidence regarding the effect of the Covid-19 pandemic on the ability of LSS at the unit level to provide efficiency at the unit level and the entire hospital at various levels of LOS.

Purpose Lean Six Sigma is a most widely used technique in quality management. In manufacturing and service industries, this technique is used for process excellence. In the power sector, there has been hardly any study on the usage of LSS. Can LSS transform the ailing power sector organization from frog into princes? The purpose of this paper is to explore LSS impact on the power sector. Design/methodology/approach A multiple case study approach is followed. Five cases, one each from the generation, the transmission and three from distribution companies are studied based on the rationale of theoretical sampling. Findings LSS is an important methodology that can be used in generation, transmission and distribution of electricity energy to drive out inefficiency and improve customer satisfaction, profits, etc. In addition, the success stories of all five cases suggest the sustainable economic benefit to the organization due to the implementation of LSS. Research limitations/implications This study intends to make an academic contribution to the pertinence of LSS in the power sector. The multiple case study approach is used on a theoretical sample of power utilities in India. This study will provide the theoretical contribution for LSS. In addition, this study will help the practitioner and managers to effectively implement LSS, especially in the power sector. Practical implications This study can be used by power sector organizations to implement LSS. A special section on implication for practice is added so that organization can make use of it while implementing LSS in the power sector. Originality/value Power is one of the most important infrastructures for the development of a country. In a developing country, the power sector is ailing; the application of LSS can transform the power sector by driving out inefficiency, waste and variation. It will not only prove to be a boon to utilities, but it will also help the customer and society at large. Consequently, it will help in reducing the power tariff, which in turn will make power financially accessible to all categories of consumers. In addition, the private investment in this sector will also improve, if power sectors appeal, to financiers as an efficient organization, compared to loss-making one organization, at present.

Purpose In the global economy, managers are constantly innovating with their use of available Lean Six Sigma (LSS) tools. Some factors, such as training and the right educational goals, have gained strong global acceptance. The purpose of this paper is to focus on contributions to organizational factors that predict organizations usage of LSS management tools to investigate expectations of project managers prior to LSS education and the extent of fulfilment of those expectations following LSS education in Slovenia, an East European country. Design/methodology/approach This research provides an empirical analysis of LSS as a learning structure and the characteristics of LSS project managers, followed by the results of an analysis of LSS usage in manufacturing companies in Slovenia following comparative surveys carried out in 2008 and 2013. Findings The top four essential characteristics for LSS organizations in 2013 include: being an innovative LSS project manager; being an effective communicator; having networking ability; and being a positive thinker. Results from 2008 to 2013 have shown differences in the stages of LSS implementation in Slovenia in these years. Differences were also seen in the level of participants’ LSS training in the studies performed. Originality/value This paper presents the first ever comparison study regarding the status of LSS education in transition countries, such as in Slovenian manufacturing companies. The study shows the expectations of participants before LSS education and their fulfilment following it. The research is original in many aspects: it includes aspects of external and internal LSS training in companies, it focusses on the manufacturing companies in the transition country of Slovenia and it provides a comparison of results in 2008 and in 2013 and an overview of the progress of LSS education. The paper will be of great value to academics, consultants, researchers, practitioners of LSS, current and future management and owners of companies in Slovenia and other similar East European transition countries. The findings will be useful in business practice for understanding the influences of education and training factors on LSS management tool usage.

Lumbar spinal stenosis (LSS) is a major cause of chronic neuropathic back and/or leg pain. Recently, we demonstrated that a significant number of macrophages infiltrated into the cauda equina after compression injury, causing neuroinflammation, and consequently mediating neuropathic pain development and/or maintenance. However, the molecular mechanisms underlying macrophage infiltration and activation have not been elucidated. Here, we demonstrated the critical role of histone H3K27 demethylase Jmjd3 in blood-nerve barrier dysfunction following macrophage infiltration and activation in LSS rats. The LSS rat model was induced by cauda equina compression using a silicone block within the epidural spaces of the L5-L6 vertebrae with neuropathic pain developing 4 weeks after compression. We found that Jmjd3 was induced in the blood vessels and infiltrated macrophages in a rat model of neuropathic pain. The blood-nerve barrier permeability in the cauda equina was increased after compression and significantly attenuated by the Jmjd3 demethylase inhibitor, GSK-J4. GSK-J4 also inhibited the expression and activation of MMP-2 and MMP-9 and significantly alleviated the loss of tight junction proteins and macrophage infiltration. Furthermore, the activation of a macrophage cell line, RAW 264.7, by LPS was significantly alleviated by GSK-J4. Finally, GSK-J4 and a potential Jmjd3 inhibitor, gallic acid, significantly inhibited mechanical allodynia in LSS rats. Thus, our findings suggest that Jmjd3 mediates neuropathic pain development and maintenance by inducing macrophage infiltration and activation after cauda equina compression and thus may serve as a potential therapeutic target for LSS-induced neuropathic pain.

Although lumbar spinal stenosis (LSS) occurs almost universally with aging, little is known regarding its actual prevalence and relationships to chronic low back pain (CLBP) in the general population. The presence of CLBP in subjects with LSS may have negative impacts on spinal alignment and mobility. This study evaluated the prevalence of LSS using a self-administered, self-reported history questionnaire in 630 community-dwelling individuals ≥50 years old. Subjects with LSS were further divided into LSS+CLBP and LSS alone groups, and spinal alignment and mobility were compared using a computer-assisted device. Prevalence of LSS was 10.8% in this cohort. Subjects in the LSS+CLBP group () showed a significantly more kyphotic lumbar spinal alignment with limited lumbar extension (), resulting in a stooped trunk compared to subjects in the LSS alone group (). However, no significant difference in spinal mobility was seen between groups.

Purpose This paper aims to investigate Lean Six Sigma (LSS) in the Brazilian context, seeking to identify its main characteristics and opportunities for future research. Design/methodology/approach This study focuses on a literature review in the area of production engineering and operations management, where 104 relevant scientific publications were identified. Findings The results show that the most important critical success factor for integrating LSS in Brazil is top management support and commitment. LSS integration occurs predominantly in large industrial companies, being incipient in small and medium-sized enterprises. In general, there is no structured way of applying LSS. A standard framework for LSS is still lacking. Research limitations/implications This study is limited to a sample that only comprises Brazilian scientific studies. Practical implications Professionals and practitioners can understand the evolution of LSS through practical applications and the main LSS tools used in both the industrial and services sectors. It also points out the critical success factor for the implementation of LSS. The study highlights several roadmaps for LSS implementation adopted by large and modern Brazilian automotive industries based on a robust technological base. This study also contributes to expanding the evidence base of LSS application, both in Brazil and in other countries. Originality/value Some suggestions are proposed to clarify the structure and complexity of integrated implementation of LP and SS as well as expand the LSS application in small and medium-sized enterprises. This study is the first to discuss the current situation of LSS in Brazil and provide suggestions to expand LSS in the country. Comparisons of Brazilian LSS literature review with researches of others countries are also presented.

Purpose The purpose of present study is to expose the detailed review for benefits and challenges about implementation of Lean Six Sigma (LSS) in business organization and spread of LSS literature in term of various sectors wise, research methodology wise and journal wise. Design/methodology/approach This paper covers the literature on LSS from 2000 to 2018. The authors have selected a large number of research papers using the keywords as Lean Six Sigma implementation in automotive, micro small medium enterprises, health care, education, financial sectors and many more. A total of 216 research papers have been reviewed on LSS distribution of sector wise, research methodology adopted, active countries, year of publication and critical barriers in implementation of LSS. Findings The present literature classifies the spread of LSS in four important sectors of manufacturing, health care, human resource, financial and education. It presents the critical barriers and benefits of LSS implementation in various sectors mentioned above and an important research gap, where practitioner/researcher can focus more during their research on LSS. Practical implications It is important for industry, researchers and LSS practitioners to be aware about challenges and success factor during LSS implementation in various sectors such as manufacturing, education, financial, human resource and health care. Hence, this paper could provide significant and valuable insights to industry and practitioners for successful implementation of LSS projects. Social implications LSS results in reduced waste, defects and improve process, which in turn provide high-quality products at minimum cost, and this leads to customer delight, which ultimately raises the societal living standard. The results encourage LSS practices without fear because there is a huge discussion of near about all success and failure parameters about LSS. Originality/value To the authors’ best knowledge, no studies have still covered the literature review of LSS implementation in three different sectors: manufacturing, service and process. The present study was mainly focused on presenting a systematic review of literature in said sectors and found the gap between current status and future direction for the implementation of LSS in different areas.

Despite the applicability of the lumbar spinal stenosis (LSS)-diagnosis support tool (DST) and the LSS-self-administered, self-reported history questionnaire (SSHQ), their diagnostic accuracy has never been compared with that of the well-known North American Spine Society (NASS) clinical description of LSS. This study aimed to compare the diagnostic accuracy of the two diagnostic tools with that of the NASS guidelines’ clinical description of LSS in a Japanese secondary care hospital setting. This multicenter cross-sectional study used data from the lumbar spinal stenosis diagnostic support tool (DISTO) project, which was conducted from December 1, 2011 to December 31, 2012. Japanese adults with low back pain (LBP) aged ≥20 years were consecutively included. The reference standard was LSS diagnosed by orthopedic physicians. The diagnostic accuracy of the two support tools was compared. Of 3,331 patients, 1,416 (42.5%) patients were diagnosed with LSS. The NASS clinical description of LSS had a sensitivity of 63.9% and specificity of 89.5%. The LSS-DST and LSS-SSHQ had sensitivities of 91.3% and 83.8% and specificities of 76.0% and 57.6%, respectively, with substantial improvements in sensitivity (P < 0.0001). Similar results were obtained when we limited included patients to those aged >60 years. These findings indicated that the LSS-DST and LSS-SSHQ were more sensitive in screening patients with LBP for a diagnosis of LSS than the NASS clinical description of LSS. This study strongly supports prioritizing the use of either of these two diagnostic support tools for screening.

Purpose The evolution of Lean Six Sigma (LSS) within the operations management theory has enjoyed significant success in both manufacturing and services. Though the applicability of LSS is evident in the services sector through various publications, academic research on the use of LSS in the Banking and Financial Services (BFS) is limited, and hence deserves greater attention. The purpose of this paper is to illustrate the application of LSS in consumer banking in real-time setting. Design/methodology/approach A case study method is used to study the application of LSS in two consumer banks with stage 1 featuring identification of appropriate consumer banks where LSS projects could be undertaken, and suitable LSS readiness assessment was performed. In stage 2, LSS project opportunities were identified in the select banks through stakeholder engagement. Finally, in stage 3, LSS projects were executed for process improvements in a real-time setting. Findings The case studies provide evidence of the successful application of LSS in consumer banking and the associated multiple benefits. The extent of applicability and appropriate managerial implications in project management context are elaborated. An LSS project selection criterion is recommended as a part of the study. Further, the study explains five important managerial implications in BFS context, with an outlook for future research. Research limitations/implications Practitioner research shows that BFS organizations have changed their ways of working by adapting LSS over the last decade. However, the academic research concerning the applicability of LSS in BFS is apparently limited, and none of these are specific to “consumer banking.” This study serves as a strong foundation for future research in this area, which is at its nascence and upcoming in the researchers’ community. However, strong generalizations should not be made as this study is limited to two cases. Practical implications Since the cases are executed in the real-time setup of consumer banks, the paper has several practical implications. First, the paper confirms the applicability of LSS in consumer banking and concludes that LSS project management is merely a sub-set of LSS deployment. Second, LSS needs to be understood using a “systems thinking” perspective in order to move away from a narrow project-only approach. An LSS project selection criterion is recommended as a part of the study, which could serve as a managerial resource. Other managerial implications include effective management of stakeholders and change leadership as essential elements of LSS project management in banks. Originality/value LSS has been successful in the past few decades in the manufacturing and service sectors. However, its application in BFS is limited. This study illustrates the applicability of LSS in consumer banks, which deals with high volumes of data, customer bases and associated financial transactions.

The expansion of renewable energy with its volatile feed-in character places higher demands on the power grid of the future. Large-scale storage systems (LSS) are a promising option for supporting the electricity grid and have been gaining importance in the last years, both on the market for frequency containment reserve (FCR) and in research. The majority of publications investigating the interaction between storage and FCR are based on simulations rather than on field measurements. This paper presents the analyses of multi-year, high-resolution field measurements of the hybrid 6 MW/7.5 MWh battery storage “M5BAT” to address this issue. The influence of FCR operation on the operation and degradation of the hybrid LSS and the individual battery technologies is investigated via a statistical evaluation of the historical operating data between 2017 and 2021. The data-based analysis of the LSS and the individual battery technologies reveals a high availability of the LSS of over 96.5%. Furthermore, the FCR operation results in an average SOC of the LSS of 50.5% and an average C-rate of the battery units of 0.081 C. A capacity test after four years of operation exposes that the lead-acid batteries have experienced a loss of energy capacity of up to 36%, whereas the lithium batteries have only experienced a loss of up to 5%. The calendar ageing predominates in this context. The presented results can be used to investigate and model the influence of FCR on the operation and battery degradation of the LSS and its different battery technologies.

Purpose. Lanosterol synthase (LSS) abnormity contributes to lens opacity in rats, mice, dogs, and human congenital cataract development. This study examined whether LSS pathway has a role in different subtypes of age-related cataract (ARC). Methods. A total of 390 patients with ARC and 88 age-matched non-ARC patients were enrolled in this study. LSS expression was analyzed by western blot and enzyme-linked immunosorbent assay (ELISA). To further examine the function of LSS, we used U18666A, an LSS inhibitor in rat lens culture system. Results. In lens epithelial cells (LECs), LSS expression in LECs increased with opaque degree C II, while it decreased with opaque degree C IV and C V. While in the cortex of age-related cortical cataract (ARCC), LSS expression was negatively related to opaque degree, while lanosterol level was positively correlated to opaque degree. No obvious change in both LSS and lanosterol level was found in either LECs or the cortex of age-related nuclear cataract (ARNC) and age-related posterior subcapsular cataract (ARPSC). In vitro, inhibiting LSS activity induced rat lens opacity and lanosterol effectively delayed the occurrence of lens opacity. Conclusions. This study indicated that LSS and lanosterol were localized in the lens of human ARC, including ARCC, ARNC, and ARPSC. LSS and lanosterol level are only correlated with opaque degree of ARCC. Furthermore, activated LSS pathway in lens is protective for lens transparency in cortical cataract.

PurposeThe purpose of this study is to propose a Lean Six Sigma (LSS) roadmap to guide healthcare practitioners in the implementation of LSS along with a customized LSS tool kit for reducing medication errors.Design/methodology/approachThe authors initially critically reviewed several frameworks/roadmaps of Lean, Six Sigma and LSS which have been proposed in healthcare sector from the existing literature. This review has led to an understanding of key characteristics, limitations and reasons behind the development of such frameworks/roadmaps. A conceptual roadmap was developed and then validated by a number of LSS experts and a healthcare practitioner. Based on the previous studies and taking LSS experts’ opinions into account, a revised roadmap for reducing medication is presented.FindingsThe roadmap for LSS in reducing medication errors is developed. This roadmap includes three phases: Phase 1 cultural readiness for LSS employment in reducing medication errors; Phase 2 preparation, initialization and implementation; and Phase 3 sustainability.Research limitations/implicationsThe roadmap has been tested with only a handful of practitioners of LSS. Moreover, only two case studies have been carried out in a Thai hospital setting which followed the roadmap. In order to improve the validity of research, more case studies need to be executed and more people should be used for testing the roadmap with varied cultures.Originality/valueThis is the first attempt in the development of a LSS roadmap that healthcare practitioners can follow to reduce medication errors using LSS methodology and sustaining LSS in their organizations.

Purpose The purpose of this paper is to examine and introduce comprehensive insights into the field of Lean Six Sigma (LSS) by reviewing the existing literature and identifying the research gap. The state of LSS research is assessed by critically examining the field, along with a number of dimensions, including time horizon, year, journal and publisher, university, country, author, geographic analysis, research design, research affairs, research methods, tools/techniques used, focus industries, major research area, benefits gained by LSS, critical success factors and barriers of LSS implementation. Design/methodology/approach This paper is based on a systematic literature review of 190 articles containing the word LSS in their title, which are published in a well-known database, such as Elsevier ScienceDirect, Taylor and Francis, Emerald Full Text, Springer Link, Wiley InterScience and Inderscience from January 2000 to September 2016. Findings This analysis reveals 15 significant dimensions to identify the state of LSS research. Authors find a noticeable rise in the attention of LSS research in the available literature. Major findings show that, the empirical research holds greater credibility. Statistics prove that the case study method scores the highest among all the research methods used in the discipline. The largest number of studies have investigated research issues related to implementation and process of LSS. The LSS uses a wide range of tools/techniques/methodologies: the choice of tools is situation-specific. Manufacturing and health-care sectors have been the focus of LSS research, but LSS has also been adopted by other types of industries. The organizations following LSS have improved bottom-line results, improved company profitability and growth and enhanced customer satisfaction. In general the research is more interpretive in nature; there is still a lack of standard in the LSS implementation framework. Research limitations/implications This study is limited to reviewing those articles which contain the word LSS appeared in the title. Originality/value This study will help understand the current state of research on LSS, various trends in the field, its applicability and future prospects of investigation in the field.

OBJECTIVELumbar spinal canal stenosis (LSS) and knee osteoarthritis (KOA), both of which are age-related degenerative diseases, are independently correlated with increased pain and dysfunction of the lower extremities. However, there have been few studies that investigated whether LSS patients with KOA exhibit poor clinical recovery following lumbar spinal surgery. The aim of this study was to elucidate the surgical outcomes of lumbar spinal surgery for LSS patients with KOA using multiple health-related quality of life (HRQOL) parameters.METHODSA total of 865 consecutive patients who underwent posterior lumbar spinal surgery for LSS were retrospectively reviewed. Baseline characteristics, radiographic parameters, perioperative factors, and multiple HRQOL parameters were analyzed preoperatively and at 1-year follow-up. HRQOL items included the Zurich Claudication Questionnaire, Oswestry Disability Index, Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ). The effectiveness of surgical treatment was assessed using the JOABPEQ. The treatment was regarded as effective when it resulted in an increase in postoperative JOABPEQ score by ≥ 20 points compared with preoperative score or achievement of a postoperative score of ≥ 90 points in those with a preoperative score of < 90 points.RESULTSA total of 32 LSS patients with KOA were identified, and 128 age- and sex-matched LSS patients without KOA were selected as controls. In both groups, all HRQOL parameters markedly improved at the 1-year follow-up. On the SF-36, the postoperative mean score for the role physical domain was significantly lower in the KOA group than in the control group (p = 0.034). The treatment was significantly less “effective” in the social life domain of JOABPEQ in the KOA group than in the control group (p < 0.001).CONCLUSIONSThe surgical outcomes of LSS patients with KOA are favorable, although poorer than those of LSS patients without KOA, particularly in terms of social life and activities. These results indicate that LSS patients with KOA experience difficulty in routine work or ordinary activities due to knee pain or restricted knee ROM even after lumbar spinal surgery. Hence, preoperative KOA status warrants consideration when planning lumbar spinal surgery and estimating surgical outcomes of LSS.

Background and Objectives: The high prevalence of lumbar spinal stenosis (LSS) and its negative impact on quality of life in the elderly is well known. However, the longitudinal time course of LSS symptoms remains unclear. The purpose of this study was to clarify the longitudinal time course and associated factors of LSS symptoms over a period of six years in a community. Materials and Methods: This study was conducted with data prospectively collected in 2004 and 2010 under a retrospective design. In 2004, 1578 subjects (age range: 40 to 79 years) were interviewed on LSS symptoms using a specially designed and validated questionnaire. In 2010, a follow-up study was performed by mail, to which 789 subjects of the 2004 study population responded. Considering that the presence of osteoarthritis (OA) of the knee or hip may influence the participants’ answers in the questionnaire, analysis was performed in all 789 subjects with and 513 subjects without either knee or hip OA. Changes in LSS symptoms between the initial and the 6-year survey were investigated. Multiple logistic regression analysis was used for detecting the risk factors for LSS symptom presence at the six-year follow-up. Results: 1. At the six-year follow-up, more than half of the subjects who showed LSS symptoms at the initial analysis became LSS-negative, and 12–15% of those who were LSS-negative became LSS-positive. 2. From the multiple logistic regression analysis, a lower Roland-Morris Disability Questionnaire (RDQ) score and a positive LSS symptom at the initial analysis were detected as predictive factors of the presence of LSS symptoms at the six-year follow-up in the total number of subjects, as well as just in those who did not have either knee or hip OA. Conclusions: More than half of the subjects who were LSS-positive at their initial assessment still experienced improvement in their symptoms even after 6 years. This means that both LSS symptoms and their time course vary from person to person. Predictive factors for the presence of LSS symptoms during the six-year follow-up period were RDQ score and positive LSS symptoms.

Purpose The purpose of this paper is to investigate the contingency effects that contextual factors of a networked service environment have on the phased Lean Six Sigma (LSS) implementation frameworks. Design/methodology/approach This paper employs the critical realism (CR) case study research methodology to examine the contingent and causal relationships between contextual configurations of business networks, the DMAIC or PDCA phases in an LSS implementation agenda, and business management functions. The authors conducted a single case study on the basis of challenges they met in kicking off lean transportation in the Port of Houston. Findings The key finding from the study is a mid-range theory regarding the contingency effects of contextual factors of service business networks on the phased LSS implementation frameworks. The authors found that when there are complexity and dynamics of contextual factors at the field layer, management should focus more on tasks in early LSS phases to emphasize influencing. When there is no centralized authority in the network and the value-system is loosely coupled, management needs to execute more tasks as described in the define, measure and analyze phases with the purpose of both influencing and orchestrating. When individual actors have goals not aligned well with the goal of the business network and have unmatched operations capabilities, these factors should be considered as early as possible in these LSS phases. When a business network has complicated business processes with high unpredictability and uncertainty and individual actors’ value-creation systems are not well embedded in the entire value-creation system, PDCA will be the preferred core structure of an LSS implementation agenda. Research limitations/implications This study contributes to the LSS research stream by introducing a causal/contingency model that prescribes the contingency effects of three contextual configurations on LSS implementation. It also contributes to the emerging discipline, business network management, regarding how to use LSS frameworks in strategic planning. It also contributes to the CR school of problem-driven case study by using a strategic initiative framework as a platform and each phase in the framework as a unit. This conceptualization of the entity of interest helps explore the interactions among three theoretical constructs: contextual configurations, phased LSS implementation agenda and management functions. Practical implications Managerial implications of this study are twofold. One is the procedure of analyzing the impacts of contextual factors on the causal relationships between LSS implementation phases and network management functions. The entire procedure represents the agenda-setting process of LSS implementation, the most daunting and challenging managerial task in LSS projects. Another one is the guideline on how to determine whether DMAIC or PDCA is appropriate for the LSS agenda when used in a networked environment. Originality/value This paper would serve as an excellent resource for both academicians and LSS practitioners in initiating, orchestrating and managing an LSS project in a networked service environment. This study represents the first effort to explore the impact of contextual factors of business networks on lean transformation.

11017 Background: Previous studies noted racial/ethnic disparities in high-grade extremity soft tissue sarcoma (ESS) treatment and overall survival (OS). Retrospective series have noted worse OS for Amputation (Amp) vs limb salvage surgery (LSS) and for LSS alone vs LSS plus radiation (RT). Given superior functional outcomes, LSS is now favored over Amp when possible. This study examines racial/ethnic disparities in receipt of Amp vs LSS and impact on OS using modern data from a national registry. Methods: The National Cancer Database was used to identify patients (pts) with stage II-III, high-grade ESS diagnosed between 2004-2014 and treated definitively with 1) Amp alone, 2) LSS alone, 3) Preoperative RT [pre RT] + LSS or 4) LSS + Post-operative RT [post RT]. Multivariate analyses (MVA) utilized logistic regressions for patterns of local treatment and Cox proportional hazards regression for OS. The Kaplan-Meier method was used to estimate 5-year OS. Results: Among 12,020 pts, receipt of LSS vs Amp did not differ significantly by race, ethnicity, age, insurance status, income, or educational attainment on MVA. The rate of Amp was higher in academic centers (OR 2.42; p = .006) or integrated network programs (OR 2.30; p = .014) vs community programs and rural vs. Metro settings (OR 1.88; p = .035). Actuarial 5-year OS by treatment was Amp 43%, LSS 59%, pre RT + LSS 61%, and LSS + post RT 66% (p < .001). On MVA, OS was worse with Amp vs. LSS alone (HR 1.37; p < .001) while pre RT + LSS (HR 0.70; p < .001) and LSS + post RT (HR 0.72; p < .001) had improved OS vs LSS alone. Treatment at a comprehensive community, academic, or integrated network programs vs community program; private insurance vs none; Hispanic vs. non-Hispanic (HR 0.85, p = .048); and higher educational attainment were associated with improved OS. More comorbidities, other primary cancers, older age, and no transitions in care were associated with worse OS. Conclusions: The only racial/ethnic disparity identified when evaluating rates of Amp and OS for ESS was a small OS benefit for Hispanic pts. OS was inferior with Amp and best with LSS with either pre RT or post RT. OS was improved at non-community programs, potentially indicating a need for referral to experienced centers.

Background: Lumbar spinal stenosis (LSS) is a clinical syndrome based on anatomic narrowing of the spinal canal. It is well known that anatomic narrowing of the spinal canal is essential for manifestation, but not all of them cause symptoms. There are many studies assessing the relationship between dural tube compression on MRI and clinical symptoms; however, most of them are cross-sectional. The purpose of this study was to reveal the magnitude of dural tube compression’s influence on the presence or development of LSS symptoms at the six-year follow-up and the occurrence of surgery during the follow-up period or not in the community setting. Methods: This was a longitudinal observational study of 459 participants who were assessed for typical LSS symptoms, and whose Roland–Morris Disability Questionnaire and numerical rating scale of leg pain and numbness was recorded using a questionnaire and conventional MRI of the lumbar spine. Typical LSS symptoms were judged using an LSS diagnostic support tool, which was a self-administered, self-reported history questionnaire (LSS-SSHQ). After six years, 232 subjects (follow-up rate 50.5%) were followed-up with typical LSS symptoms using LSS-SSHQ by mail. The relationship between the magnitude of dural tube compression evaluated by dural tube cross-sectional area (DCSA) in the initial assessment and the time course of typical LSS symptoms for the six-year duration were analyzed. In addition, predictors of the presence of typical LSS symptoms at the six-year follow-up were assessed. Furthermore, we investigated the relationship between typical LSS symptoms and DCSA during the initial assessment of patients who underwent surgery during the follow-up period. A multivariate logistic regression analysis was performed for statistical analysis. Results: (1) Severe dural tube compression did not show that LSS symptoms continued after six years. (2) Severe dural tube compression could not detect development of LSS-symptoms and surgery during the six-year period. Conclusion: Severe dural tube compression could not detect typical LSS symptom development and occurrence of surgery during the six-year period.

While Lean Six Sigma (LSS) has been applied extensively in healthcare organisations, there has been limited research on the trends of LSS application in healthcare in recent years. This paper aims to present the key motivations and benefits of LSS in healthcare with a view to highlighting the types of problems that LSS in healthcare can aid in solving. The authors used a systematic literature review (SLR) approach to achieving the article’s purpose. Peer-reviewed journal articles published between 2011 and 2021 are considered to achieve the study objectives. The systematic review helped the authors to identify the evolution, benefits, and motivations for LSS in healthcare. This work includes directions for managers and healthcare professionals in healthcare organisations to embark on a focused LSS journey aligned with the strategic objectives. This study is perhaps one of the most comprehensive SLRs covering a vital agenda of LSS in healthcare. This study provides all the deliverables of LSS for its successful deployment in healthcare.

Purpose This paper aims to illustrate the usefulness of stakeholder analysis for managing Lean Six Sigma (LSS) projects effectively. Design/methodology/approach This research is based on an LSS case study that was initiated in a New Zealand public sector organisation. Findings A ten-step stakeholder analysis framework was applied to a public sector organisation in New Zealand. This analysis identified the stakeholders and their stakes, analysed the efficiency of their stakeholder management processes and evaluated the effectiveness of transactions between the stakeholders and the LSS project management. It also captured the changing salience of stakeholders during an LSS project. Practical implications The stakeholder analysis framework illustrated in this paper provides a practical toolset for managers involved in LSS projects. Originality/value Although some LSS experts have conducted a preliminary stakeholder analysis, the LSS literature lacks concrete examples of a thorough stakeholder analysis. This study tries to address this research gap by illustrating a stakeholder analysis framework for a New Zealand-based LSS project.

Purpose. We investigated self-reported quality of life (QoL), body image and daily competence of patients as a consequence of limb salvage surgery (LSS), primary or secondary amputation, and the views of patients following secondary amputation.Patients. Patients (n=37) had all been treated for osteosarcoma or Ewing's sarcoma in the lower limb.Methods. QoL was measured by questionnaire. A separate interview to determine satisfaction with decision-making was conducted with those treated for secondary amputation.Results. For the total group, QoL was below that expected from population norms. There were no differences in QoL between those undergoing LSS surgery compared with amputation. However, LSS reported better daily competence and were less likely to use a walking aid. For the total group, body image and daily competence were associated with better QoL.Discussion. All these patients are at risk of compromised QoL following surgery. Our data are in line with previous work suggesting outcomes may be better for LSS compared with amputation. Following secondary amputation, most patients (80%) did not regret initial LSS treatment, but felt that the time gained allowed them to come to terms with subsequent surgery.

Purpose The purpose of this paper is to empirically investigate the applicability and implementation of Lean Six Sigma (LSS) in Higher Education Institutions (HEIs). LSS is considered as the most recent service quality practice which has proved its success in manufacturing and service sectors. Though there is plenty of literature available with regard to the application and benefits of LSS in services sectors (like Banking, healthcare, information technology sectors, etc.), there is apparently no evidence in the literature about the implementation of LSS in HEIs. Design/methodology/approach A five-phased approach is followed. A multiple case-study method is used in this paper to explore this implementation of LSS in two select international University colleges. LSS toolkit comprising of define-measure-analyze-improve-control phases is used for the execution of the projects. Featuring student teams in LSS project management adds novelty to the approach. Findings The paper empirically validates the application of LSS in HEIs. Further, it highlights the practical challenges and benefits of LSS in the HEI setup. An in-depth empirical analysis of LSS toolkit application, LSS change management and using student teams in LSS project management are the highlights of this paper. The paper concludes that LSS is applicable and could provide positive benefits to HEIs. Research limitations/implications LSS application in HEIs is perhaps a new research area, which is at its nascence and upcoming in the researchers’ community. Hence, this paper would serve as a platform and provide directions for future scholars to ponder on the subject. Practical implications Since the cases are executed in the real-time setup of HEIs, the paper has several practical implications. First, the academia and practitioners’ collaboration in executing projects adds novelty. Second, the involvement of student teams from project selection to execution brings in practical perspectives alongside the academic education. Several other key lessons learned and benefits of LSS in HEI setup are presented as part of the paper. Originality/value LSS has been successful in the past few decades in the manufacturing and service sectors. However, its application in HEIs was very nascent, and few researchers even doubted its relevancy of application in HEIs. This study illustrates its importance and application to the higher education sector which is a highly responsible area of the service sector, for imbibing quality excellence, serving as an excellent resource for researchers and higher education professionals.

IntroductionSoreness is a common complaint in patients who receive lumbar spine surgery (LSS) for degenerative lumbar spine diseases (DLSD). However, soreness is not assessed independently and its impacts on outcomes of LSS remains largely unknown. Sng(pronounced sә-ng, 痠) in Chinese language is the word with the closest meaning to soreness, and Chinese-speaking people naturally use sng to describe their non-pain ‘soreness’ symptom. This study was aimed to investigate the prevalence and impacts of soreness or sng on outcome of LSS by introducing Visual Analogue Scale (VAS) of sng on back and leg.Materials and methodsThis prospective cohort study recruited patients who receive LSS for DLSD. Participants completed the patient-reported outcome measures at 1 week before and 1 years after LSS. The patient-reported outcome measures included (1) VAS for back pain, leg pain, back sng and leg sng, (2) Oswestry Disability Index (ODI) and (3) RAND 36-item Short Form Health Survey. The minimal clinical important difference (MCID) of ODI and physical component health-related quality of life (HRQoL) was used.ResultsA total of 258 consecutive patients were included and 50 dropped out at follow-up. Preoperatively, the prevalence of sng was comparable to pain both on back and leg; postoperatively, the prevalence of sng was higher than pain. Leg and back sng were associated with preoperative and postoperative mental HRQoL, respectively. The reduction of sng on back and leg were significantly less than pain postoperatively. Leg sng was the only symptom independently associated with attaining MCID.ConclusionSoreness or sng should be assessed independently from pain in patients receiving LSS for DLSD because soreness or sng had substantial clinical impacts on the outcome of LSS.

Background. Recently, “over the top” (also called ULBD; microscopic unilateral laminotomy for bilateral decompression) is a less invasive technique for symptomatic degenerative lumbar spinal stenosis (LSS), and this minimally invasive surgical technique has demonstrated favorable therapeutic outcomes. However, the risk of postoperative complications remains controversial. Objective. This study is aimed at determining the clinical efficacy and complication and rehabilitation of the microscopic “over the top” for degenerative LSS in geriatric patients. Study Design. This was a retrospective study. Setting. All data were obtained from the People’s Hospital of a University. Methods. A retrospective analysis of 39 consecutive elderly patients treated for LSS by microscopic “over the top” between January 2016 and January 2018 was performed. A postoperative rehabilitation program for geriatric patients with restricted weight-bearing was instituted after the microscopic “over the top” treatment. Estimated blood loss, duration of operation, length of hospitalization, and total complications were also evaluated. The CT and MRI examinations of the lumbar spine were collected to evaluate the completeness of the nerve decompression. Clinical data were assessed at 6 months and 12 months after operation utilizing the visual analog scale (VAS), Oswestry Disability Index (ODI), and 36-Item Short-Form Health Survey (SF-36). Preoperative comorbidities, complications, and revision surgery were also recorded. Results. We enrolled a total of 39 degenerative LSS patients (27 male and 12 female patients, mean age of 75.8 ± 9.2 years). Twenty patients had one-level of degenerative LSS; thirteen patients had two-level of LSS; six patients had three-level of LSS. The average follow-up time in our study was 14.6 ± 7.8 months (range, 6-24 months). The overall complication rate was 10.2% (4/39), and the reoperation rates at one year were 2.5% (1/39). VAS back and leg pain score at 6 months were decreased to 1.8 ± 0.7 and 1.4 ± 0.6 , respectively, and remained at 1.9 ± 0.3 and 1.2 ± 0.2 at 12 months, respectively. ODI scores improved significantly from 32.26 ± 6.82 to 11.44 ± 2.50 at 6 months and 10.56 ± 2.29 at 12 months. 36-Item Short-Form Health Survey scores revealed a significant improvement throughout follow-up. Postoperative complications included dural tear ( n = 2 ), neurologic deficit ( n = 1 ), and reoperation ( n = 1 ). No infections or hematomas were reported. Limitation. Multicenter research is recommended to confirm our results and investigate the factors related to clinical and radiographic results. Conclusions. Microscopic “over the top” technique is a safe, effective option in the therapy of degenerative LSS and obtained satisfactory functional outcomes when coupled with aggressive rehabilitation, with a long recurrence-free recovery.

PurposeThe purpose of this research is to develop a better understanding of the hurdles in implementing Lean Six Sigma (LSS) for operational excellence in digital emerging technology companies.Design/methodology/approachWe have conducted case studies of LSS implementations in six US-based companies in the digital emerging technology industry.FindingsCritical success factors (CSF) for LSS implementations in digital emerging technology companies are: (1) organizational leadership that is engaged to the implementation, (2) LSS methodology that is rebranded to fit existing shared values in the organization, (3) restructuring of the traditional LSS training program to include a more incremental, prioritized, on-the-job training approach and (4) a modified LSS project execution methodology that includes (a) condensing the phases and tools applied in LSS projects and (b) adopting more iterative project management methods compared to the standard phased LSS project approach.Research limitations/implicationsThe qualitative nature of our analysis and the geographic coverage of our sample limit the generalizability of our findings.Practical implicationsImplications comprise the awareness and knowledge of critical success factors and LSS methodology modifications specifically relevant for digital emerging technology companies or companies that share similarities in terms of focus on product development, innovation and growth, such as R&D departments in high-tech manufacturing companies.Originality/valueResearch on industry-specific enablers for successful LSS implementation in the digital emerging technology industry is virtually absent. Our research informs practitioners on how to implement LSS in this and alike industries, and points to aspects of such implementations that are worthy of further attention from the academic community.

PurposeThis paper compares impact of Industry 4.0 / emerging information and communication Technologies (ICTs), for example, Internet of things (IOT), machine learning, artificial intelligence (AI), robotics and cloud computing, on 22 organisational performance indicators under nine combinations of Lean Six Sigma (LSS) and quality management systems (QMS).Design/methodology/approachSurvey of 105 Indian organisations was done about their experience of using QMS, Lean Six Sigma and emerging ICTs. Respondents included both manufacturing and service enterprises of different scales and sectors. The responses collected were compared, and statistically significant difference among them was evaluated using chi-square test.FindingsThe study confirmed statistically significant difference among 20 organisational performance indicators under different combinations of QMS, LSS and ICTs. These indicators include quality performance, delivery performance, sales turnover, inventory level and so forth. However, for two indicators, namely, absenteeism and throughput, significant difference in responses was not established.Research limitations/implicationsAll possible combinations of QMS, LSS, only LSS tools and ICTs were not studied because of either theoretical impossibility (e.g. using LSS without LSS tools) or practically rare situations (e.g. organisations using ICTs and LSS without QMS). Furthermore, the impact from different sequences of implementing QMS, LSS and ICTs can be studied.Practical implicationsUsing this study, practitioners can identify which LSS, Quality System and ICT combination results in best performance and quick success. On theoretical front, the study confirms impact of LSS and QMS on organisational performance.Originality/valueThis study evaluates organisational performance under several possible combinations of QMS, LSS, and emerging ICTs, which was so far unexplored.

Purpose – The purpose of this paper is to investigate the migratory nature of Lean Six Sigma (LSS) implementation and adoption in manufacturing-based SMEs in the UK. The companies were surveyed at two points over a five-year period. These periods were before and after the 2008 recession point. This being done in order to identify the level of LSS adoption as a result of the tougher economic climate that has prevailed since 2008. Design/methodology/approach – Analysis is carried out on a sample of 96 manufacturing SMEs from a range of manufacturing sectors in the UK. Data were gathered from company CEOs via a triangulated method of questionnaire, direct observation and interviews. Findings – The paper provides research information into the characterisation, compatibility and innovativeness of SMEs towards LSS implementation and goes on to provide an implementation classification system and characterises the dynamical nature of LSS development in manufacturing SMEs. Research limitations/implications – The findings analyse the dynamic nature of LSS implementation in SMEs. Further work will include extending the LSS categorisation system to provide a wider category set that further defines the dynamical nature of LSS implementation. Also, more focused studies in to specific manufacturing sectors will yield greater understanding of the effects of LSS on those sectors. Practical implications – The paper provides practical research information into the characterisation, compatibility and innovativeness of SMEs towards LSS implementation. It will be of use to practitioners seeking to implement or develop LSS further in their organisations. Originality/value – This study compares at depth the LSS implementation issues within SMEs. It not only analyses the survey data but characterises their attitudes towards implementing LSS and as such this work makes a contribution to this under researched area.
