Abstract:
The expectation of greater individual responsibility for health promotion practices and decision making in hospitals is dependent upon knowledgeable consumers. The heavy reliance on printed material for both gathering and disseminating information in hospitals has led to recommendations that literacy screening tests be considered to enhance the efficacy of patient teaching interventions for the significant number of adults with low literacy skills. A qualitative case study design was used to investigate the response of adults with low literacy skills to literacy screening. Data were collected through in depth interviews including an experience using the Rapid Estimate of Adult Literacy in Medicine (REALM) word recognition tool. Analysis was achieved using a constant comparison technique. A conceptual model of response to screening was developed and compared to the Health Belief Model and Knox's Proficiency Theory of adult learning. While all participants supported the principle of screening in the context of the hospital, response to the REALM experience was variable. Factors found to influence responses to screening included perceived risks of illiteracy exposure, perceived risks of non-disclosure during hospitalization and the attribution of characteristics to the hospital leading to it's designation as a "special" place. Specific responses to the REALM were found to be further influenced by a set of individual historic factors. The results have lead to several recommendations for health care professionals considering utilization of literacy screening instruments.

Full text
Abstract:
In this dissertation is proposed a methodology to identify patient's recovery patterns after cardiovascular surgery based on laboratory tests results. The main purpose is to enhance the understanding of the manifestations of postsurgical complications in patients who underwent cardiovascular surgery. The analysis of patients' recovery process is based on the relationship between plasma calcium, ionized calcium and platelet count over time. Laboratory results from the James A. Haley Veterans' Hospital databases, related to patients admitted to the Surgical Intensive Care Unit (SICU) after cardiac surgery (coronary artery bypass, aortic value replacement and mitral valve replacement), are used. These databases contain information regarding commonly ordered tests such as Complete Blood Count tests (CBC) and Basic Metabolic Panel (BMP) for a large group of patients over time. Physicians usually order these tests as a component of screening, routine evaluation, or serial assessment. These test results, contain a large amount of information used by most physicians during the diagnosis process and patient monitoring. This study creates time series of some components of the aforementioned tests to analyze their behavior during the perioperative and postoperative period. Time series based clusters are developed to determine the similarities among tests results from four different types of patients: patients who had a satisfactory recovery process without any manifestation of complications, patients who experienced complications but survived, viii patients who experienced complications and then died during their recovery and patients who died during the perioperative period. As a conclusion, the time series based clustering techniques were able to identify whether a patient is likely to fully recover from the surgery, but it does not have the power to detect effectively results corresponding to a patient experiencing complications. The development of this methodology provides statistical evidence of the differences among different patterns on patient recovery. It is clear that patients experiencing complications have a steeper drop of test results after surgery, and also a non-stable trend towards normal levels. The appropriate use of the proposed methodology could help to timely anticipate complications in patient condition, improve the comprehensiveness of the assessment of patient condition based on laboratory test results and enhance the utilization of laboratory results databases.

Abstract:
The electric pulp test (EPT) has been shown to be a valuable tool in assessing pulp vitality. One of its drawbacks, however, is its high number of false positives. The purpose of this study was to determine if qualifying the type of sensation elicited by the test could lower the percentage of false positive responses. A retrospective chart review of an eleven-month period was conducted, examining all patients with necrotic teeth tested with the EPT. Of 189 teeth, when the patient responded to EPT at first sensation 23.3% of teeth were incorrectly identified as vital. When the patient was asked to respond only if they felt an uncomfortable sensation, the false positive rate was lowered to 8.5%, a statistically significant difference. No association was found between the teeth reclassified as necrotic and age, gender, type of tooth, or number of canals.

Abstract:
Objectives. To compare four diverse approaches to measuring patient perceptions about health outcomes; the SF-36 Health Survey; clinically derived condition specific instruments; daily time trade-off (DTTO); patient generated index (PGI). The relationship between the instruments and their responsiveness to changes in Health Related Quality of Life (HRQL) was assessed. Results. The response rate exceeded 75% (1327 respondents). The SF-36 had Cronbach's Alpha values above the criterion of 0.7. Test-retest estimates were above 0.7 for al but the role-limitations scales which were above the criterion of 0.5. The specific instruments produced Alpha values and test-retest estimates above 0.7. The DTTO and PGI produced estimates of reliability above 0.5. Evidence for the construct validity of the SF-36 was demonstrated by the differences in scale scores between the general population and four condition-specific groups. Evidence for the construct validity of the specific instruments and PGI was demonstrated by the significant moderate levels of correlation with the SF-36. Evidence for the validity of all four approaches was demonstrated by patient scores behaving as predicted in relation to condition-specific and sociodemographic variables. Comparisons of the four approaches show that the relationship between them is condition dependent. Score changes for the SF-36, specific instruments and PGI were significantly related to self reported health transition. The SRMs for the specific instruments were significantly greater than those for the SF-36. Conclusions. These results demonstrate that the SF-36 has similar properties in United Kingdom patient populations as those in the United States and is satisfactory for comparisons of groups. The clinically derived approach is recommended for constructing instruments where no suitable condition-specific instrument exists. These two approaches are recommended for use as part of a package of instruments for assessing health outcomes.

Abstract:
Antibiotic resistance is an increasing global public health problem. Resistance is increasing sharply in gram-negative organisms, including Escherichia coli (E. coli), the main causative organism for community-acquired urinary tract infection (UTI). Antimicrobial stewardship strategies in primary care to help contain antibiotic resistance include supporting general practitioners (GPs) in deciding whether to prescribe an antibiotic for UTI and selecting the most appropriate antibiotic. In this thesis, I aim to describe the management of uncomplicated UTI in primary care and evaluate potential point of care tests (POCT) to assist the diagnosis and/or appropriate prescribing of antibiotics for uncomplicated UTI. The program of work includes: 1. Laboratory evaluation of a culture-based test that allows the quantification, identification and susceptibility profile of infecting bacteria from urine (FlexicultTM). 2. Evaluation of a novel chromatic sensing technique to identify bacterially infected urine compared to visual assessment of urine turbidity and urinalysis dipsticks. 3. Systematic review and analysis of data (descriptive and multi-level modelling) from an international primary care based observational study to describe UTI management. I identified unwarranted variation in clinical management of UTI between countries and between general practices within countries. Empirical antibiotic prescribing for UTI in Europe is high and treatment is generally prescribed for longer than guidelines recommend. FlexicultTM identifying bacterial UTI. The use of FlexicultTM in practice may support GPs in screening out negative samples reducing the proportion of patients that are prescribed antibiotics empirically. Chromatic sensing and visually assessing turbidity were equally useful at identifying negative urine samples and both improved the analytic performance of urinalysis dipsticks. The chromatic sensing system requires development prior to further evaluation.

Full text
Abstract:
The first goal of this investigation was to undertake a non-equivalent quasi-experimental design to test the effect of a total Quality management (TQM) approach to improve the appropriateness of clinical laboratory test utilisation in the management of early acute myocardial infarction (AMI). The study was conducted at 2 public hospitals in Sydney over a 30 month period, and in 2 stages- pre and post TQM intervention. Using specifically a Continuous Quality Improvement (CQI) FOCUS-PDCA model, a multidisciplinary team was empowered to make appropriate changes in order to improve a variety of problem areas that affected the total pathology service. Improvement was directed at the total system of pathology testing, not just test ordering. It was observed that the introduction of a TQM environment had provided a more committed, integrated and motivated clinical care effort towards improving the appropriateness of test ordering. Such team efforts were accompanied by demonstrated customer satisfaction at various aspects of the laboratory service and further benefits to patient care. Patient care benefited greatly from the highly significant changes towards more appropriate timing of blood collections for cardiac enzyme testing. Other improvements included overall improvements to the turnaround time of test results, reductions in specimen delivery delays, more appropriate use of clinical laboratory tests, a streamlined distribution of printed reports and marked improvements in communication between staff involved in the process of test ordering. Of major importance was the finding that CQI strategies resulted in substantial savings of 23.0% of the overall cost of pathology services. Adoption of the TQM approach appears to be a strategy worthy of exploration by laboratory directors and health administrators interested in improving patient care while at the same time reducing expenditure.

ENGLISH ABSTRACT: Back pain is a common concern amongst a growing population of people across the world today, where in most cases the pain can become unbearable resulting in major lifestyle adjustments. Seventy to eighty percent of the population of the Western world experiences low-back pain at one time or another. Pain can be produced as a worn disc becomes thin, narrowing the space between the vertebrae. Pieces of the damaged disc may also break off and cause irritation to the nerves signalling back pain. Depending on the severity of a patient’s condition, and after conservative treatment options have been exhausted, a disc replacement surgery (arthroplasty) procedure may be prescribed to restore spacing between vertebrae and relieve the pinched nerve, while still maintaining normal biomechanical movement. Typical complications that are however still observed in some cases of disc implants include: anterior migration of the disc, subsidence (sinking of disc) and lateral subluxation (partial dislocation of a joint). Issues such as function, correct placement and orientation, as well as secure fixation of such a disc implant to the adjacent vertebrae are highly important in order to replicate natural biomechanical behaviour and minimise the occurrence of the complications mentioned. As various imaging and manufacturing technologies have developed, the option for individual, patientspecific implants is becoming more of a practical reality than it has been in the past. The combination of CT images and Rapid Manufacturing for example is already being used successfully in producing custom implants for maxilla/facial and cranial reconstructive surgeries. There exists a need to formalise a process chain for the design and manufacture of custom-made intervertebral disc implants and to address the issues involved during each step. Therefore this study has investigated the steps involved for such a process chain and the sensible flow of information as well as the use of state-of-the-art manufacturing technologies. Strong emphasis was placed on automation of some of the processes as well as the user-friendliness of software where engineers and surgeons often need to work together during this multi-disciplinary environment. One of the main benefits for customization was also investigated, namely a reduction in the risk and potential for implant subsidence. Stiffness values from pressure tests on vertebrae were compared between customized implants and implants with flat endplate designs. Results indicated a statistically significant improvement of customized, endplate matching implants as opposed to flat implant endplates. Therefore it may be concluded that the use of customized intervertebral disc implants with patient specific endplate geometry may decrease the risk and potential for the occurrence of subsidence.
AFRIKAANSE OPSOMMING: Rugpyn is ‘n algemene bekommernis vir ‘n groeiende populasie van mense in die wêreld vandag, waar in meeste gevalle die pyn ondraagbaar kan raak en groot leefstyl aanpassings vereis. Sewentig tot tagtig persent van die populasie in die Westerse wêreld ondervind lae rugpyn op een of ander stadium. Die pyn kan veroorsaak word deur ‘n intervertebrale skyf wat verweer en dunner word, en veroorsaak dat die spasie tussen die vertebrae vernou. Stukkies van die beskadigde skyf mag ook afbreek en irritasie aan die senuwees veroorsaak wat verdere pyn kan veroorsaak. Afhangende van die ernstigheid van ‘n pasiënt se geval, en nadat opsies vir konservatiewe behandeling uitgeput is, kan ‘n skyf vervangings-prosedure (artroskopie) voorgeskryf word om die spasie tussen die vertebrae te herstel en sodoende die geknypte senuwee te verlos. Die skyf vervanging herstel spasiëring tussen vertebrae terwyl die normale biomeganiese beweging ook behoue bly, in teenstelling met ‘n fusieprosedure wat die betrokke vertebrae aanmekaar vasheg en normale beweging belemmer. Tipiese komplikasies wat egter steeds na ‘n skyf vervanging in sommige gevalle waargeneem word sluit in: anterior migrasie van die inplantaat, insinking, sowel as laterale sublukasie (gedeeltelike dislokasie van ‘n gewrig). Faktore soos funksie, korrekte posisionering en orientasie, sowel as vashegting van so ‘n skyf inplantaat tot die aanliggende vertebrale bene is besonder belangrik om natuurlike biomeganiese beweging te herstel en sodoende bogenoemde komplikasies te verminder. Soos wat verskeie beeldings- en vervaardigingstegnologië verbeter het oor die laaste dekade, het die moontlikheid vir individuele, pasiënt-spesifieke inplantate al hoe meer ‘n praktiese realiteit begin word. Die kombinasie van Gerekenariseerde Tomografie (GT), tesame met Snel Vervaardiging word byvoorbeeld reeds suksesvol aangewend tydens die ontwerp en vervaardiging van pasiënt-spesifieke inplantate vir maksilla- en kraniale rekonstruktiewe chirurgie. Daar bestaan egter ‘n behoefte om ‘n formele prosesketting vir die ontwerp en vervaardiging van pasiënt-spesifieke intervertebrale skyf inplantate te ontwikkel en om belangrike faktore tydens elke stap noukeurig te beskryf. Hierdie studie het na die verskillende stappe in die prosesketting gekyk om ‘n sinvolle vloei van informasie en benutting van hoë gehalte vervaardigingstegnologië saam te snoer. Sterk klem was gelê op outomatisering van prosesse asook gebruikersvriendelikheid van sagteware waar ingenieurs en medici dikwels saam moet werk tydens hierdie kruisdissiplinêre omgewing. Een van die hoof verwagte voordele met die gebruik van pasklaar skyf inplantate, naamlik die vermindering van moontlike insinking van die inplantaat in die been, is ook ondersoek. Die ondersoek het druktoetse behels en die vergelyking van ooreenstemmende styfheid tussen inplantate wat die kontoer van die bene volg teenoor gewone plat eindplate. Die resultate was statisties beduidend in die guns van die pasklaar inplantate wat die beenkontoere gevolg het, en bewys dus dat die risiko vir insinking verminder is.

Abstract:
AbstractLaboratory medicine in the healthcare system has recently been recognized as a fundamental service in the clinical decision-making process. Therefore, the notion of patient safety in laboratory medicine must be recognized as the assurance that harm to patients will be avoided, safe care outcomes will be enhanced through error prevention, and the total testing process (TTP) will be continuously improved.Although the goal for patient safety is zero errors, and although laboratory professionals have made numerous efforts to reduce errors in the last few decades, current research into laboratory-related diagnostic errors highlights that: (a) errors occur at every step of the TTP, mainly affecting phases at clinical interfaces; (b) despite the improvement strategies adopted, analytical quality remains a challenge; (c) errors are linked not only to clinical chemistry tests, but also to new, increasingly complex diagnostic testing.Medical laboratories must therefore implement effective quality assurance tools to identify and prevent errors in order to guarantee the reliability of laboratory information. Accreditation in compliance with the International Standard ISO 15189 represents the first step, establishing processes with excellence requirements and greater expectations of staff competency. Another important step in preventing errors and ensuring patient safety is the development of specific educational and training programs addressed to all professionals involved in the process, in which both technical and administrative skills are integrated. A wide variety of information is provided by a robust quality management system and consensus-approved Quality Indicators (QI) that identify undesirable events, evaluate the risk to the patient, and call for corrective and preventive actions. However, the effectiveness of the system depends on the careful analysis of data collected and on staff awareness of the importance of laboratory medicine to the healthcare process. The main task of the new generation of laboratory professionals should be to gain experience in “clinical laboratory stewardship.” In order to safeguard patients, laboratory professionals must assist clinicians in selecting the right test for the right patient at the right time and facilitate the interpretation of laboratory information.

Abstract:
This study presents implementation of an object fetching task with a mobile robotic platform (PR2) for hospital patients. The primary goal of this study is to define the requirements for a robotic nursing assistants. The designed application scenario consists of PR2 robotic platform, human subject as the patient, and a tablet for patient-robot communication. The PR2 robot understands patient’s request and fetches the requested object by performing automated action steps. For this designed scenario, human subject experiments are performed. Furthermore, all human subject test results are presented and observations during tests are provided. These activities are part of a larger effort to establish adaptive robotic nursing assistants for physical tasks in hospital environments.

Abstract:
Depression and anxiety are the most prevalent mental disorders, reaching million people worldwide. As they share many characteristics these two disorders can manifest themselves together. In addition, stress is one of the related factors with both depression and anxiety, being relevant in the analysis of these disorders. This paper proposes a model for ubiquitous care of patients with depression, anxiety and stress disorders (DASD) using gamification and biodata, called iAware. A/B tests evaluated with a clinical population the interaction engagement of the patient to the treatment provided by gamification. Based on the patient’s history, the iAware monitors and applies interventions for the patient at the most appropriate time. Six patients used a prototype with a smartband for two weeks to evaluate iAware. Interactions with intervention stages were greater in patients who used iAware gamified. A more detailed analysis is still required. The evaluated patients got more occurrences of anxiety at home. The patients also filled out a survey based on the Technology Acceptance Model (TAM). TAM results show that patients have found the iAware useful in their anxiety treatment routines.

Abstract:
The bleeding time (BT) is one of the most important screening tests in patients with a bleeding tendency. Investigations of Von Willebrand Factor and aggregation tests form routine diagnostic tools to analyse a prolonged BT. In many patients, however, this approach fails to explain the bleeding tendency because no abnormality is found. In order to deal with this problem , we chose three methods: I) determination of platelet nucleotides and serotonin in all patients with a prolonged BT, independent of the results of aggregation tests, II) measurement of platelet adherence to purified collagen and the matrix of endothelial cells in a perfusion system, III) measurement of adherence of normal blood to matrix of patients' fibroblasts. I) In a group of 145 patients with a prolonged BT and a normal platelet count the diagnosis von Willebrand1's disease was made in 52 patients (36%), congenital Storage Pool Disease (SPD) in 27 pts (18%), defect of thromboxane synthesis in 4 pts (3%) and platelet function disorders with miscellaneous aggregation abnormalities in 23 pts (16%). No abnormalities were found in 39 pts (27%). Analysis of aggregation tests, disclosed normal aggregation tracings in many patients with SPD: 23% of 106 patients with congenital or acquired SPD had normal aggregation tests.Adhesion studies were performed with the blood of 7 patients with an unexplained prolonged bleeding time. Two patients had a severe defect and one patient a mild defect of adherence. Further studies revealed the presence of an autoantibody on the platelets in one of these patients.In order to diagnose vessel wall defects which may cause a prolonged BT, we studied the adherence of normal blood to the matrix of the fibroblasts of one patient. We found a decreased adherence, which suggests the presence of a vessel wall defect causing a prolonged BT.We conclude that in many patients with a prolonged BT and normal VWF parameters and normal aggregation tests, SPD or adhesion defects may be responsible for a bleeding tendency.

Full text
Abstract:
Continuous positive airway pressure (CPAP) therapy is considered the most effective treatment for patients with Obstructive Sleep Apnea (OSA) symptom. A CPAP mask is the interface between the patient and the CPAP humidifier, which contains a series of orifice to circulate the air and ensure that the expired carbon dioxide from the patient's breathing is not rebreathed. The flow through those orifices is called bias flow. For the existing CPAP mask, this bias flow rate increases as the CPAP pressure increases. This raised bias flow rate usually causes a bigger pressure swing inside the mask when the patient is breathing, which is unfavorable for OSA therapy due to the much bigger breathing load required. However, a minimum bias flow rate needs to be maintained inside the mask in order to keep carbon dioxide concentration low. Therefore, this paper introduces a novel mask that can produce a relatively constant bias flow rate (CBFR) over a CPAP range of 0-20cm H2O. Dynamic response tests have proved that this CBFR mask can constrict the mask pressure swing by an order of two so as to offer better comfort for OSA patients.

Abstract:
We describe the completeness of prenatal data in maternal delivery records and the prevalence of selected medical conditions and complications among patients delivering at community hospitals around Atlanta, Georgia. Medical charts for 199 maternal-infant dyads (99 infants in normal newborn nurseries and 104 infants in newborn intensive care nurseries) were identified by medical records staff at 9 hospitals and abstracted on site. Ninety-eight percent of hospital charts included prenatal records, but over 20 percent were missing results for common laboratory tests and prenatal procedures. Forty-nine percent of women had a pre-existing medical condition, 64 percent had a prenatal complication, and 63 percent had a labor or delivery complication. Missing prenatal information limits the usefulness of these records for research and may result in unnecessary tests or procedures or inappropriate medical care.

Full text
Abstract:
Because many patients reduce exercise following outpatient cardiac rehabilitation (CR), we developed an intervention to assist with the transition and evaluated its feasibility and preliminary efficacy using a one-group pretest–posttest design. Five CR patients were enrolled ~1 month prior to CR discharge and provided an activity tracker. Each week during CR they received a summary of their physical activity and steps. Following CR discharge, participants received an individualized report that included their physical activity and step history, information on specific features of the activity tracker, and encouraging messages from former CR patients for each of the next 6 weeks. Mixed model trajectory analyses were used to test the intervention effect separately for active minutes and steps modeling three study phases: pre-intervention (day activity tracking began to CR discharge), intervention (day following CR discharge to day when final report sent), and maintenance (day following the final report to ~1 month later). Activity tracking was successfully deployed and, with weekly reports following CR, may offset the usual decline in physical activity. When weekly reports ceased, a decline in steps/day occurred. A scaled-up intervention with a more rigorous study design with sufficient sample size can evaluate this approach further.

Abstract:
This quality improvement project was completed to show that a formal lung transplant education course for nurses caring for lung transplant patients increased their knowledge. An eight-hour education course was developed by experts in the field of lung transplantation. A pretest was administered before the education course. A posttest was administered to determine if knowledge was improved. A three-month follow-up test was administered to determine knowledge retention. Based on the data analysis, nurse knowledge improved after formal education. Item analysis determined what areas of educational content need to be the focus of quarterly education. The education course was adopted as formal training for transplant nurses.
