Karlsson, Johan. "Information structures and workflows in health care informatics." Doctoral thesis, Umeå universitet, Institutionen för datavetenskap, 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-33829.
Full textAbstract:
Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. personalized medicine) and in secondary uses such as data mining, this is complex to realize due to technical, commercial and legal issues related with combining and refining patient data. Clinical decision support systems (CDSS) are great catalysts for enabling evidence-based medicine in clinical practice. Although patient data can be the base for CDSS logic, it is often scattered among heterogenous data sources (even in different health care centers). Data integration and subsequent data mining must consider codification of patient data with terminology systems in addition to legal and ethical aspects of using such data. Although computerization of the patient record systems has been underway for a long time, some data is still unstructured. Investigation regarding the feasibility of using electronic patient records (EPR) as data sources for data mining is therefore important. Association rules can be used as a base for CDSS development. Logic representation affect the usability of the systems and the possibility of providing explanations of the generated advice. Several properties of these rules are relatively easy to explain (such as support and confidence), which in itself can improve end-user confidence in advice from CDSS. Information from information sources other than the EPR can also be important for diagnosis and/or treatment decisions. Drug prescription is a process that is particularly dependent on reliable information regarding, among other things, drug-drug interactions which can have serious effects. CDSS and other information systems are not useful unless they are available at the time and location of patient care. This motivates using mobile devices for CDSS. Information structures of interactions affect representation in informatics systems. These structures can be represented using a category theory based implementation of rough sets (rough monads). Development of guidelines and CDSS can be based on existing guidelines with connections to external information systems that validate advice given the particular patient situation (for example, previously prescribed drugs may interact with recommended drugs by CDSS). Rules for CDSS can also be generated directly from patient data but this assumes that such data is structured and representative. Although there is great potential in CDSS to improve the quality and efficiency of health care, these systems must be properly integrated with existing processes in health care (workflows) and with other information systems. Health care workflows manage physical resources such as patients and doctors and can help to standardize care processes and support management decisions through workflow simulation. Such simulations allow information bottle-necks or insufficient resources (equipment, personnel) to be identified. As personalized medicine using genetic information of patients become economically feasible, computational requirements increase. In this sense, distributing computations through web services and system-oriented workflows can complement human-oriented workflows. Issues related to dynamic service discovery, semantic annotations of data, service inputs/outputs affect the feasibility of system-oriented workflow construction and sharing. Additionally, sharing of system-oriented workflows increase the possibilities of peer-review and workflow re-usage.

Full textAbstract:
Prologue is a health information system developed for underserved communities in Bihar, India. It is aimed at helping people living in poverty and with low literacy to take the right steps to manage their and their family’s health. Bihar suffers from one of the worst healthcare records in the country. This is as much due to the lack of access to the right information as it is due to the economic condition of the region. The inaccessibility of information is aggravated by the complex social set up in these communities, for e.g. women aren’t allowed to leave their homes and community has the strongest influence on an individual’s decision making. To make sure that right information permeates even to the most inaccessible user groups, especially women and to uplift community’s awareness as a whole, two different communication channels were designed-an interactive radio show and a public installation.

Eivazzadeh, Shahryar. "Health Information Systems Evaluation." Licentiate thesis, Karlskrona, 2015. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-10910.
Full textAbstract:
Background Health information systems have emerged as a major component in our response to the trends of rising demands in health care. The insight being gained from the evaluation of those systems can critically influence the shaping of the response. Summative or formative evaluation of health information systems assesses their quality, acceptance, and usefulness, creates insight for improvement, discriminates between options, and refines future development strategies. But the evaluation of health information systems can be challenging due to the propagation of their impacts through multiple socio-technological layers till the ultimate recipients, their heterogeneity and fast evolvement, and the complexity of health care settings and systems. Aim This thesis tries to explain the challenges of evaluation of health information systems with a narrow down on determining evaluation aspects and to propose relevant solutions. The thesis goes for solutions that mitigate heterogeneity and incomparability, recruit or extend available evaluation models, embrace a wide context of application, and promote automation. Method The literature on health information systems evaluation, methods of dealing with heterogeneity in other disciplines of information systems, and ontology engineering were surveyed. Based on the literature survey, the UVON method, based on ontology engineering, was first developed in study 1. The method was applied in FI-STAR, a European Union project in e-Health with 7 use-cases, for summative evaluation of the individual and whole e-health applications. Study 2, extended the UVON method for a formative evaluation during the design phase. Results Application of the UVON method resulted in evaluation aspects that were delivered to the seven use-cases of the FI-STAR project in the form of questionnaires. The resulted evaluation aspects were considered sensible and with a confirming overlap with another highly used method in this field (MAST). No significant negative feedback from the FI-STAR use-case owners (n=7) or the respondents (n=87 patients and n=30 health professionals) was received or observed. Conclusion In the evaluation of health information systems --possibly also in other similarly characterized systems-- ontology engineering methods, such as the proposed UVON method, can be applied to create a flexible degree of unification across a heterogeneous set of evaluation aspects, import evaluation aspects from other evaluation methods, and prioritize between quality aspects in design phase. Ontologies, through their semantic network structures, can capture the extracted knowledge required for evaluation, facilitate computation of that knowledge, promote automation of evaluation, and accommodate further extensions of the related evaluation methods by adding new features to their network structure.

Hirvonen, N. (Noora). "Health information matters:everyday health information literacy and behaviour in relation to health behaviour and physical health among young men." Doctoral thesis, Oulun yliopisto, 2015. http://urn.fi/urn:isbn:9789526210407.
Full textAbstract:
Abstract This study increases the understanding of young men’s everyday health information literacy and behaviour in relation to their health behaviour, physical health, and socio-demographic characteristics. The conceptual framework of the study builds upon theories of information behaviour, practices and literacy, and health behaviour change. The empirical data were collected with questionnaires (n = 3,293) and physiological measurements (n = 3,063) in 2010 to 2013 at the Finnish Defence Forces’ call-ups, where a population-based sample of young Finnish men could be reached. Everyday health information literacy was studied using a previously developed screening tool, and with a focus on its relationship with health behaviour and physical fitness. Information behaviour was investigated in the context of physical activity, and in relation to men’s readiness to change exercise behaviour according to the Transtheoretical Model. Statistical analyses of the data include multivariate regression analyses, and a critical realist approach was adopted in interpreting the results. The results show that general upper secondary education and higher socio-economic position of a parent increase the likelihood of good health information literacy. Health information literacy is positively associated with health-promoting behaviour and health independent of socio-economic position; confidence in one’s abilities to find, evaluate and use health information is associated with regular exercise and healthy eating habits, and good physical fitness, for example. In the context of physical activity, the practices used to acquire information are associated with the stage of exercise behaviour change. Men in the maintenance stage seek information most actively. Information avoidance, in turn, is connected to low health information literacy, not to the stage of change. The study provides novel knowledge on healthy young people’s everyday health information literacy and behaviour, and on their relationship. It is among the first to investigate health information behaviour in the stages of behaviour change and health information literacy in connection with objectively measured fitness. It proposes a framework for future studies on the relationship between health information literacy and behaviour, and health information outcomes. The results may be utilised when designing tailored health communications and health information literacy educationTiivistelmä Tutkimus lisää ymmärrystä siitä, millainen yhteys nuorten miesten arkielämän terveystiedon lukutaidolla ja terveystietokäyttäytymisellä on terveyskäyttäytymiseen, fyysiseen terveyteen ja sosiodemografisiin tekijöihin. Sen käsitteellinen viitekehys rakentuu tietokäyttäytymisen ja -käytäntöjen, terveystiedon lukutaidon sekä terveyskäyttäytymisen muutoksen teorioille. Tutkimuksen aineisto kerättiin kyselyillä (n = 3 293) ja fysiologisilla mittauksilla (n = 3 063) vuosina 2010–2013 Puolustusvoimien Oulun alueen kutsuntatilaisuuksissa, joissa oli mahdollista saavuttaa suomalaisten nuorten miesten väestöpohjainen otos. Terveystiedon lukutaitoa arvioitiin aiemmin kehitetyllä seulontavälineellä sekä suhteessa terveyskäyttäytymiseen ja fyysiseen kuntoon. Terveystietokäyttäytymistä tarkasteltiin liikunnan kontekstissa ja suhteessa transteoreettisen mallin mukaiseen liikuntakäyttäytymisen muutosvalmiuteen. Aineistot analysoitiin tilastollisesti monimuuttujamenetelmin, ja tuloksia tulkittiin kriittisen realismin näkökulmasta. Tulokset osoittavat, että lukiokoulutus ja korkeassa sosioekonomisessa asemassa oleva vanhempi lisäävät hyvän arkielämän terveystiedon lukutaidon todennäköisyyttä. Terveystiedon lukutaito on positiivisesti yhteydessä terveyttä edistäviin elintapoihin ja terveyteen sosioekonomisesta asemasta riippumatta. Luottamus omiin kykyihin löytää, arvioida ja ymmärtää terveystietoa on yhteydessä muun muassa säännölliseen liikuntaan ja terveellisiin syömistottumuksiin sekä hyvään fyysiseen kuntoon. Liikunnan kontekstissa terveystietokäytännöt kytkeytyvät käyttäytymisen muutosvaiheeseen. Aktiivisimmin liikuntatietoa hankkivat liikuntakäyttäytymisen ylläpitovaiheessa olevat. Tiedon välttäminen sen sijaan on yhteydessä alhaiseen terveystiedon lukutaitoon, ei muutosvaiheeseen. Tutkimus tuottaa uutta tietoa nuorten, terveiden ihmisten arkielämän terveystiedon lukutaidosta ja terveystietokäyttäytymisestä sekä niiden suhteesta toisiinsa. Uutta on myös terveystietokäytäntöjen tutkiminen terveyskäyttäytymisen muutosvaiheissa ja terveystiedon lukutaidon tarkastelu suhteessa objektiivisesti mitattuun fyysiseen kuntoon. Tutkimuksessa esitetään viitekehys tuleville tutkimuksille terveystiedon lukutaidon ja tietokäytäntöjen vaikutuksesta terveyteen. Tulokset ovat hyödynnettävissä räätälöidyn terveysviestinnän ja terveystiedon lukutaidon koulutuksen suunnittelussa

Enwald, H. (Heidi). "Tailoring health communication:the perspective of information users' health information behaviour in relation to their physical health status." Doctoral thesis, Oulun yliopisto, 2013. http://urn.fi/urn:isbn:9789526202792.
Full textAbstract:
Abstract The aim of this thesis was twofold: firstly, to increase understanding about the user of health information; namely about differences of users´ characteristics of health information behaviour, and secondly, to contribute to the research on factors that could be used as bases to tailor health information. Health information behaviour was scrutinised as information needs and seeking and information use in particular. It was also studied in relation to individuals´ physical health status. More studies on information use are needed, because understanding individual characteristics in issues related to information use has been considered critical for promoting healthy behaviours. Moreover, the thesis addressed the gap in research on the relationship between health information behaviour and tailoring health information. The thesis consists of three empirical studies and a literature review. The empirical research environments were provided by an intervention study aiming to prevent type 2 diabetes among a high risk population and by a population-based study among military conscription aged men. The setting was the City of Oulu in Northern Finland with the University of Oulu and the Oulu Deaconess Institute as the main operators of the studies. The empirical data were collected through questionnaires as well as through physiological and biochemical measurements during years 2010 and 2011. The data were analysed with statistical methods. Moreover, a literature review of tailored interventions studies using a computer as the medium of delivery in the context of physical activity, nutrition and weight management, was conducted. The findings indicate differences in health information users´ characteristics related to their information use as such and in relation to the indicators of their physical health status. It is suggested that, for example, health information presentation could be tailored on the basis of found differences and different message strategies and tactics could be used for different kinds of individuals. In addition, in the literature review the biases of tailored intervention studies stood out as influential on their outcomes. The thesis contributes to the current field of research on both health information behaviour and tailoring health communication. Moreover, the findings can support the development of more effective health promotion programs and intervention studiesTiivistelmä Väitöskirjatutkimukseni tavoitteena on lisätä ymmärrystä terveystiedon käyttäjistä ja erityisesti heidän terveysinformaatiokäyttäytymiseensä liittyvistä ominaisuuksista. Tutkimukseni tuottaa tietoa tekijöistä, joita voidaan käyttää terveystiedon räätälöinnin lähtökohtana. Terveysinformaatiokäyttäytymistä tarkastelen tiedontarpeiden ja -hankinnan sekä erityisesti tiedon käytön näkökulmasta. Informaatiokäyttäytymistä tutkitaan myös suhteessa tiedon käyttäjän fyysiseen terveydentilaan. Tutkimukseni vastaa tarpeeseen tutkia tiedon käyttäjiä, sillä tiedon käyttöön liittyvien yksilöllisten ominaisuuksien ymmärtäminen on keskeistä terveyden edistämisessä. Väitöskirja tuottaa uutta tietoa myös informaatiokäyttäytymisen ja terveystiedon räätälöinnin välisestä suhteesta. Väitöskirjani käsittää neljä osajulkaisua: kolme empiiristä tutkimusta ja kirjallisuuskatsauksen. Empiiriset tutkimukset toteutettiin tyypin 2 diabeteksen ehkäisyyn tähtäävän interventiotutkimuksen (PreDiabEx) ja väestöpohjaisen tutkimuksen (MOPO) tarjoamissa tutkimusympäristöissä. Tutkimusten kohteina olivat miehet ja naiset, joiden riski sairastua tyypin 2 diabetekseen oli korkea sekä kutsuntaikäiset miehet. Tutkimukset toteutettiin Oulussa ja päätoteuttajia olivat Oulun yliopisto ja Oulun Diakonissalaitos. Empiirinen aineisto kerättiin kyselyillä sekä fysiologisilla ja biokemiallisilla terveydentilaa ilmaisevilla mittareilla vuosien 2010 ja 2011 aikana. Aineisto analysoitiin tilastollisesti. Kirjallisuuskatsauksessa analysoidaan fyysisen aktiivisuuden, ravitsemuksen ja painonhallinnan interventiotutkimuksia, joissa tarkastellaan terveystiedon räätälöinnin vaikuttavuutta silloin, kun tiedonvälitykseen käytetään tietokonetta. Empiiristen tutkimusten tulokset viittaavat siihen, että niin terveystiedonkäyttäjien ominaisuuksissa informaatiokäyttäytymisessä kuin sen suhteessa heidän fyysisen terveydentilaansa on eroja. Terveystietoa tulisikin esittää eri tavoin erilaisille ihmisille, muun muassa erilaisia viestistrategioita ja -taktiikoita käyttäen. Kirjallisuuskatsauksen tulokset lisäsivät ymmärrystä siitä, miten tutkimusasetelman vinoumat voivat vaikuttaa interventiotutkimusten tuloksiin

Full textAbstract:
The purpose of this study was to investigate patient use and presentation of Internet health information and its effect on patient-health professional relationship from a sample of residents at active adult communities in Texas. Five sites were used to recruit the 260 participants between November 2012 and January 2013. The data were received using a self-administered survey. Using Cronbach’s alpha, logistic regression and regression analysis through SAS, the data revealed that older respondents are less likely to discuss web-based information with health professionals. In addition, logistic regression analysis indicated that four of the variables, IHI Sharing, educational status (bachelor degree), marital status (married), and perceived health status (excellent and very good health) predicted varied of the 20 indicators making up the patient-health professional relationship scale. Further studies are needed to enhance this research.

Full textAbstract:
Healthcare organizations now consider increased efficiency, reduced costs, improved patient care and quality of services, and safety when they are planning to implement new information and communication technology (ICT) based applications. However, in spite of enormous investment in health information systems (HIS), no convincing evidence of the overall benefits of HISs yet exists. The publishing of studies that capture the effects of the implementation and use of ICT-based applications in healthcare may contribute to the emergence of an evidence-based health informatics which can be used as a platform for decisions made by policy makers, executives, and clinicians. Health informatics needs further studies identifying the factors affecting successful HIS implementation and capturing the effects of HIS implementation. The purpose of the work presented in this thesis is to increase the available knowledge about the impact of the implementation and use of HISs in healthcare organizations. All the studies included in this thesis used qualitative research methods. A case study design and literature review were performed to collect data.
This thesis’s results highlight an increasing need to share knowledge, find methods to evaluate the impact of investments, and formulate indicators for success. It makes suggestions for developing or extending evaluation methods that can be applied to this area with a multi-actor perspective in order to understand the effects, consequences, and prerequisites that have to be achieved for the successful implementation and use of IT in healthcare. The results also propose that HIS, particularly integrated computer-based patient records (ICPR), be introduced to fulfill a high number of organizational, individualbased, and socio-technical goals at different levels. It is therefore necessary to link the goals that HIS systems are to fulfill in relation to short-term, middle-term, and long-term strategic goals. Another suggestion is that implementers and vendors should direct more attention to what has been published in the area to avoid future failures.
This thesis’s findings outline an updated structure for implementation planning. When implementing HISs in hospital and primary-care environments, this thesis suggests that such strategic actions as management involvement and resource allocation, such tactical action as integrating HIS with healthcare workflow, and such operational actions as user involvement, establishing compatibility between software and hardware, and education and training should be taken into consideration.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Economics, 2011.Cataloged from PDF version of thesis.
Includes bibliographical references (p. 151-155).
This thesis consists of three essays on information, decision-making and health. All three concern the relationship between the choices consumers would make if they were "fully informed" in an appropriate sense and the choices we actually observe. Chapter 1 considers how we can determine whether consumers are appropriately taking into account health information when they make their food consumption decisions. The fundamental idea is to determine the value of a statistical life (VSL) implicit in food consumption decisions and to compare this value with previous estimates of the VSL. The main positive result is that the VSL estimated from food consumption is about 1/10th as large as estimates from other contexts. I also consider the normative implications under the assumption that VSL estimates from other contexts indicate how individuals would behave if they were "fully informed" and discuss what additional evidence might support such an assumption. Chapter 2, co-authored with Jonathan Gruber, performs an analogous exercise in the case of health care plans. Where Chapter 1 makes the normative assumption that consumers should value years of life equally regardless of where they come from (e.g. eating healthier foods or reducing risk of on-the-job death), Chapter 2 makes the normative assumption that consumers should value a dollar of cost savings equivalently whether it comes through premiums or out of pocket costs. This restriction can then be used to evaluate whether consumers are choosing appropriately. The chapter studies this question in the context of Medicare Part D Prescription Drug Plan, the most significant privatization of the delivery of a public insurance benefit in recent history. Chapter 3 attempts to consider the circumstances in which the partial equilibrium welfare analyses performed in parts 1 and 2 extend to a general equilibrium setting in which prices and product characteristics respond endogenously to changes in demand. In particular, Chapter 3 derives conditions under which more information leads to welfare gains in general equilibrium taking into account the endogenous response of firms' pricing and product quality decisions.

Full textAbstract:
Diese Dissertation umfasst vier Manuskripte zum Thema Risikokommunikation und medizinischen Entscheidungen. Das erste Manuskript diskutiert Unterschiede, Gemeinsamkeiten und die Anwendbarkeit von drei zentralen Ansätzen, die helfen sollen, bessere Entscheidungen zu treffen (Nudging, Social Marketing, Empowerment). Das zweite Manuskript präsentiert Ergebnisse einer Medienanalyse zur Evaluation von Zeitungs- und Internetberichten in Deutschland und Spanien über die HPV-Impfung. Basierend auf vordefinierten Standards für transparente, vollständige und korrekte Risikokommunikation, deckt die Medienanalyse Schwächen in der Berichterstattung auf. Das dritte Manuskript untersucht wie Laien relative Risikoreduktionen bzw. –erhöhungen, ein Standardformt in der Medizin, verstehen. Beide Formate führen Laien und Experten in die Irre und führen zur Überschätzung der tatsächlichen Effekte. Ein diskutierter Ausweg ist die zusätzliche Kommunikation der Basisrate. Die Ergebnisse zeigen, dass das Verständnis von relativen Risikoreduktionen (-erhöhungen) mit Basisrate von dem Präsentationsformat (Prozent- vs. Häufigkeitsformat) und der individuellen Fähigkeit im Zahlenverständnis abhängt. Teilnehmer mit geringem Zahlenverständnis profitierten von der Darstellung in Häufigkeiten; Teilnehmer mit hohem Zahlenverständnis zeigen ein besseres Verständnis unabhängig des Formats. Dennoch—selbst mit Basisrate—missverstehen viele Teilnehmer die Risikoinformation. Das vierte Manuskript untersucht wie Teilnehmer Behandlungen unter Unsicherheit auswählen. Ein Einwand gegen die Kommunikation von Unsicherheit ist die Behauptung, dass Menschen Unsicherheit in Gewinnsituationen vermeiden, in Verlustsituationen dagegen suchen. Die Ergebnisse dieser Studie in Bezug auf die Auswahl von medizinischen Behandlungen konnten diese Annahmen nicht bestätigen. Darüber hinaus wählte die Mehrheit der Teilnehmer die gleiche Behandlung, wenngleich sich die zugrundeliegende Auswahlstrategie unterschied.This dissertation comprises four manuscripts focusing on health risk communication and medical decision making. The first manuscript discusses differences, commonalities, and the applicability of three major approaches to help patients make better decisions: nudging, social marketing, and empowerment. The second manuscript presents results of an evaluation of media coverage about the HPV vaccine of newspaper and Internet reports in Germany and Spain. Based on predefined standards for transparent, complete, and correct risk communication, the analysis revealed substantial shortcomings in how the media informed the public. The third manuscript centers on a standard format to communicate treatment benefits and harms: relative risk reductions and increases. Such formats have been found to misinform and mislead patients and health professionals. One suggestion is to always include information about baseline risk to reduce misunderstandings. Results show that even when baseline risk was communicated, it depended on the presentation format (percentage vs. frequency) and people’s numeracy skills whether they correctly interpreted the risk reduction (or increase). Low numerates benefited from a frequency format, whereas high numerates performed better independent of the format. Yet, a substantial proportion of participants still misunderstood the meaning of a relative risk reduction (or increase). The fourth manuscript investigated how laypeople choose between medical treatments when ambiguity is present. One objection against communicating ambiguity is the claim that laypeople are ambiguity averse in the domain of gains and ambiguity seeking in the domain of losses. Results did not find supporting evidence for this claim in medical treatment choice. Moreover, most participants selected the same treatment option, independent of numeracy. However, the underlying choice strategies varied between individuals.

Full textAbstract:
The greatest wealth is health. It is sometimes said your health is a function of what you are not doing, not what you are currently doing. The degree to which individuals can attain, process, and comprehend the necessary health information and services they need to make proper health decisions is vital for optimal health and well-being.
This project documents the analysis, design, development, and implementation of a prototype web-based data-driven health & wellness system targeted for college students. The architecture for this system uses business intelligence to develop a smart online platform for real-time analysis based on inputs entered by its users.
The objective is to develop modules that can be used to provide meal plan options that dietitians can recommend to students, while also providing a standard wellness health check. This also promotes constant awareness for students with specialized health diets. User-health and wellness history of each Student is collected and stored for generating progress and wellness reports for end users. The dietitian can monitor the user in real time through the data collected and stored in the data server. Users can monitor their own progress. The system incorporates user context and feedback to personalize each user's lifestyle.
Implementation of this system provides a complete and easy to use integrated system that promotes the process of analyzing wellness and improving the user’s overall health. The system is designed to be in a non-clinical setting and hence more lifestyle-oriented compared to other health-oriented systems. It is thus more relevant and convenient to student’s everyday life context.

Full textAbstract:
This thesis explores the use of the Internet as a search tool for health information, examining how information practices are inscribed within, and what the implications are for, individuals' everyday experience of health. It does not solely examine the Internet, but also embraces the mediated context of health that promotes information practices. The study examines the search for health-related information from the perspective of information seekers and within the informational environment of individuals' everyday life that shapes an 'informed health' experience. The study draws on sociological theories that discuss contemporary health experience and the related issues of risks, information and agency. It is based on a web-based questionnaire and qualitative email and face-to-face interviews with Internet users. After a descriptive analysis of health information seekers' profiles and their online practices, three interpretive contexts - 'informed patient', 'informed self' and 'healthy self' - explore the everyday dimension and meanings of health information seeking. Four case studies of online health information seekers are next developed, deepening the investigation of the significance of being informed about one's own health. The thesis also reflects on the use of email as an interview method and on its implications for the online research relationship. The thesis demonstrates how information seeking may be part of a 'health role' indicating individuals' responsibility for maintaining and controlling their own good health by means of information. It outlines how information seeking may be the source of uncertainties and produce resistance from information seekers who may deliberately ignore information or construct alternative health projects through information selection. The study discusses the implications for the doctor-patient relationship of seeking health information and demonstrates how using the Internet for health information generates an attitude of suspicion in laypersons who must redefine the trust they place in sources of information, including in medical professionals.

Full textAbstract:
The formative study investigated health information for seniors on the Internet with consideration of usability of the selected system, user's perceived ease of use, perceived usefulness, system use, and performance, i.e. information retention. A theoretical model was developed by the researcher, i.e. JAM's Senior Health Information Technology Acceptance Model, as an enhanced version of the traditional Davis Technology Acceptance Model. The new model provided the critical relationship between the senior health information system and other technology acceptance components. Computer self-efficacy was added to the hypothetical model to better explain the seniors' technology usage and performance. The hypotheses and the research plan included: four professional experts, who assessed the site for usability, and 68 of 145 seniors who began the survey completed a three-part senior participant survey. Data was collected by a third party and the author. Implications for seniors, professionals, and society are presented. The senior population is the subject of the research. Professionals working with seniors, the Internet, health information, and technology acceptance are served by the formative study to further clarify the relationship of the issues. The topic is considered a societal issue as a large segment of the population is composed of seniors. Their welfare and interests impact society and other generations. The results suggested computer self-efficacy is irrelevant for perceived ease of use and perceived usefulness however self-efficacy contributed to information retention. Usability affects perceived ease of use and perceived usefulness. There is a highly significant, though not very strong, relation between those variables. Perceived usefulness is a good indicator of a return visit to the site and senior recommendations of the site to others. These are two new variables that were not included in the model. There is no relationship between usability and computer self-efficacy. There was significance between usability and system use, but little relevance has pointed toward information retention (IR). The results of the analysis suggest that the hypothesized model information retention level did not predict senior IR based on human factor professionals' and senior users' usability ratings. Attrition according to qualitative feedback was the result of browser and equipment issues, ease of use and navigation. Future research endeavors should be devoted to usability and use of other systems for the senior population.Ph.D.

Full textAbstract:
This thesis addresses the question of the design, production and use of information graphics in health technology assessment (HTA). Drawing on previous research in both information design and health policy, it describes a comprehensive design process for creating new visual presentations that can inform health policy-makers. The thesis begins by introducing, and functionally defining the terms ‘information graphics’ and ‘health technology assessment’ in Chapter 1. It then offers a methodological discussion of how research can be performed at the intersection between these two diverse fields. This discussion forms Chapter 2 of the thesis. The context of use is surveyed in two studies, which are presented in Chapter 3. These assess the current use of information graphics in HTA, and the information needs of health policy decision-making bodies. This enables a needs-based approach to the design of 10 information graphics, that could be used in hta. These are shown in Chapter 4. Finally, two of these information graphics are empirically tested with two further research studies, forming Chapter 5 and Chapter 6. The thesis is aimed at giving practical advice to those wanting to produce graphical presentations of information in HTA, and to provide the foundation for further original research in information design and HTA. Chapter 7 draws together the research from the rest of the thesis, to make recommendations in light of the combined findings.

The research presented in this thesis investigated aspects of health information on the Internet. Firstly, an investigation of how the newspaper media influence public perception of the Internet as a health information source is described. Newspaper reporting in the period 2003-2012 was found to be infrequent, and was mainly limited to the "quality" press. Reporting on online health information peaked when public health was threatened, for example during the H 1 N1 influenza pandemic in 2009. Secondly, a survey of health information seeking by people with chronic illness and the outcomes of obtaining health information from the Internet is reported. Online health information seekers used most sources of health information to a greater extent" and had higher health status scores, than offline health information seekers. The majority of online health information seekers reported improved knowledge, although some were worried by the information they had obtained. Thirdly, a thematic analysis of the content of an on line discussion forum for adults with cystic fibrosis is presented. Generally, forum members initiated discussions in response to acute changes in their health and shared experiences rather than factual information. Health-related challenges that are faced by adults with cystic fibrosis, such as dealing with acute symptoms, medication use and coping with deteriorations in their health were identified. In addition, issues related to daily living aspects were reported. Fourthly, surveys undertaken in 2005 and 2012 investigated the impact of the Internet on the professional practice of general practitioners (GPs) and community pharmacists. By 2012, GPs had incorporated use of the Internet into their practice to a greater extent than pharmacists. For example, GPs recommended web sites to patients four times more frequently than community pharmacists. Finally, the implications of the overall findings of the programme of research, for health professionals and the public, and for future research, are discussed

Objective: To determine if a personal digital assistant (PDA) with drug and evidence-based disease information software programs and with librarian training and follow-up can adequately meet at low cost the information needs of clinicians in rural areas with low information availability.
Methods: A randomized clinical trial methodology was used. Eight hospitals were selected in rural Appalachia based on accepted definitions of rurality. The hospitals were randomized into two groups of four hospitals with forty PDA users in each group. Both groups were treated equally, except the information needs of one group were measured using a validated instrument before the intervention and in the other group several months later. The survey instrument measured factors such as level of satisfaction with information retrieved in the clinic, required time to find an answer, and frequency of answers found for clinical questions.

The internet has radically changed the way people obtain and interact with information about diseases, treatments, and conditions. Yet, our understanding of how people access and use health information to make decisions- in other words, their health literacy- has not progressed. The overall aim of this thesis is to assess the extent to which health literacy is a valid and useful construct for policy and practice related to online health resources. A mixed-methods research programme of five studies was undertaken, influenced by realist evaluation methodology. First, to ascertain engagement with user-generated online health content (UGC) in the UK, analysis of a large European survey was undertaken. Then, the uncertainty regarding the relationship between health literacy and outcomes was addressed by a systematic review and qualitative analysis of health literacy measures. Results of these two studies informed interviews carried out with 13 'key informants': policymakers and primary care clinicians in the UK with a particular interest in health literacy and/or online information. A systematic review, incorporating a traditional narrative review and a realist review, evaluated existing trials addressing how effects of online resources vary by health literacy level. Finally, data were analysed from a feasibility randomized controlled trial, comparing usage and outcomes of accessing a 'personal experiences'-based asthma website (representing curated user-generated content) versus a 'facts and figures'-based website. Participant health literacy was assessed using an index identified from the systematic review of measures, and website usage was tracked. Approximately 25% of UK internet users engage with UGC at least monthly. The most frequent users were younger, more likely to be male, and to be carers for someone with a long-term illness. Three themes were identified from health literacy measurement: 'appropriate health decisions', 'ability to obtain healthcare services', and 'confidence'. Key informants noted the lack of clarity about how health literacy influences outcomes, and suggested that personal preferences and digital access and skills may be more relevant than health literacy for policy and practice. Existing trials of online resources in which participant health literacy was measured were mostly at high risk of bias; some possible explanations of how these interventions should work in people with low health literacy were that they may experience higher data entry burden related to chronic diseases, and that they may prefer simulated face-to-face communication. Finally, there were no differences between health literacy groups in the feasibility trial regarding usage or outcomes related to either the 'facts and figures' or 'personal experiences' websites. Taken together, these results question the validity and appropriateness of health literacy as a key objective or consideration in the development or use of online resources. While health literacy has value as a general idea, this thesis demonstrates that it may no longer be the right construct to guide intervention development and implementation to improve health outcomes.

Consumers face several challenges using the Internet to fill health-related needs. (1) In many cases, they face a language gap as they look for information that is written in unfamiliar technical language. (2) Medical information in social media is of variable quality and may be appealing even when it is dangerous. (3) Discussion groups provide valuable social support for necessary lifestyle changes, but are variable in their levels of activity. (4) Finding less popular groups is tedious. We present solutions to these challenges.
We use a novel adaptation of topic models to address the language gap. Conventional topic models discover a set of unrelated topics that together explain the combinations of words in a collection of documents. We add additional structure that provides relationships between topics corresponding to relationships between consumer and technical medical topics. This allows us to support search for technical information using informal consumer medical questions.
We also analyze social media related to eating disorders. A third of these videos promote eating disorders and consumers are twice as engaged by these dangerous videos. We study the interactions of two communities in a photo-sharing site. There, a community that encourages recovery from eating disorders interacts with the pro-eating disorder community in an attempt to persuade them, but we found that this attempt entrenches the pro-eating disorder community more firmly in its position.
We study the process by which consumers participate in discussion groups in an online diabetes community. We develop novel event history analysis techniques to identify the characteristics of groups in a diabetes community that are correlated with consumer activity. This analysis reveals that uniformly advertise the popular groups to all consumers impairs the diversity of the groups and limits their value to the community.
To help consumers find interesting discussion groups, we develop a system for personalized recommendation for social connections. We extend matrix factorization techniques that are effective for product recommendation so that they become suitable for implicit power-law-distributed social ratings. We identify the best approaches for recommendation of a variety of social connections involving consumers, discussion groups and discussions.

Bibliography: leaves 120-127.The literature relating to women's health in Africa focuses on health information seeking needs. It rarely focuses on how women's health information needs link to the development of the continent. The dissertation examines the interrelationships between women's health information needs and development. The study sought to establish the significance of information to women's health and development. In order to validate this link the study employed three data collection techniques - documentary research, interviews and electronic mail questionnaires. In illustrating that there is a relationship between women's health and development, the study argues that women's empowerment can only be achieved where sufficient information is provided for women to make informed independent decisions concerning health issues that affect them. This relates especially to when to have children; how to protect themselves against AIDS, what the early warning signals of breast and cervical cancer are, and how best to look after their children and the community at large. The study further argues that these types of challenges can only be met with an efficient and effective health information service that is both gender sensitive and context specific to the African continent.

Book Summary The book takes an open and encompassing approach to exploring evidence based library and information practice (EBLIP) and the ways it can improve the practice of librarianship. Bringing together recent theory, research, and case studies, it provides librarians with a new reference point for how they can use and create evidence within their practice, in order to better meet the needs of their communities.
Being Evidence Based in Library and Information Practice is divided into two parts; in the first part the editors explore the background to EBLIP and put forward a new model for its application in the workplace which encompasses five elements: Articulate, Assemble, Assess, Agree, Adapt. In the second part, contributors from academic, public, health, school, and special libraries from around the world provide an overview of EBLIP developments and offer examples of successful implementation.
Essential reading for library and information professionals from all types of institutions who want to make more informed decisions and better meet the needs of their users, this book will also be of interest to students of library and information studies and researchers.

The growth of e-health system has influenced the way health organizations conducttheir business. Communication between these systems is one of the most significantfactors since a more efficient communication system can improve an organizationperformance. Nowadays the health organizations make a lot of investments to deploya suitable information and communication technology to meet their goals.This study investigates the health information exchange within different healthinformation systems. We first carried out a theoretical study to find out the relevantconcepts by reviewing the related literature and analyzing them. As a result of ourtheoretical study we investigate and redesign the basic model of the “Super Clinic” asa new model for health information exchange system. Then we conducted anempirical study to validate the result from the theoretical study which helped us tonarrow down our research area. We revised our proposed theoretical model by thelesson learnt from our empirical study results. Three interviews were conducted withexperts and the outcomes were analyzed using comparative analysis. These interviewsallowed us to outline the most important factors of successful health informationexchange systems (i.e. “Super Clinic”).They also helped us to design a central hub (i.e. “health Hub”) for communicationand information exchange between different information systems.

There is a marked trend of using information technologies to improve healthcare. Among all the health IT, electronic health record (EHR) systems hold great promises as they modernize the paradigm and practice of care provision. However, empirical studies in the literature found mixed evidence on whether EHRs improve quality of care. I posit two explanations for the mixed evidence. First, most prior studies failed to account for system use and only focused on EHR purchase or adoption. Second, most existing EHR systems provide inadequate clinical decision support and hence, fail to reveal the full potential of digital health. In this dissertation I address two broad research questions: a) Does meaningful use of EHRs improve quality of care? and b) How do we advance clinical decision making through innovative computational techniques of healthcare analytics? To these ends, the dissertation comprises four essays. The first essay examines whether meaningful use of EHRs improve quality of care through a natural experiment. I found that meaningful use significantly improve quality of care, and this effect is greater in historically disadvantaged hospitals such as small, non-teaching, or rural hospitals. These empirical findings present salient practical and policy implications about the role of health IT. On the other hand, in the other three essays I work with real-world EHR data sets and propose healthcare analytics frameworks and methods to better utilize clinical text (Essay II), integrate clinical guidelines and EHR data for risk prediction (Essay III), and develop a principled approach for multifaceted risk profiling (Essay IV). Models, frameworks, and design principles proposed in these essays advance not only health IT research, but also more broadly contribute to business analytics, design science, and predictive modeling research.

This research was a qualitative study that explored the experience of health information literacy. It used a research approach that emphasised identifying and describing variation in experience to investigate people's experience of using information to learn about health, and what they experienced as information for learning about health. The study's findings identified seven categories that represented qualitatively different ways in which people experienced health information literacy, and provide new knowledge about people's engagement with health information for learning in everyday life. The study contributes to consumer health information research and is significant to the disciplines of health and information science.

This research investigated the question of whether automatic or system-generated information classification methods can help humans better manage information. A series of four experiments were conducted; they investigated the usability (i.e., usefulness) of two automatic approaches to information classification, the concept space approach and a Kohonen-based SOM approach in the context of information retrieval. The concept space approach was evaluated in three different domains: Electronic Brainstorming (EBS) sessions, the Internet, and medical literature (the CancerLit collection). The Kohonen-based SOM approach was evaluated in the Internet and medical literature (CancerLit) domains only. In each case, the approach under investigation was compared with existing systems in order to demonstrate performance viability. The basic premise that information management, in particular information retrieval, can be successfully supported by system-based information classification techniques and that humans would find such techniques viable and useful was supported by the experiments. The concept space approach was more successful than the Kohonen-based SOM approach. After modifications to the algorithms based on user feedback from the EBS experiments had been made, users found the concept space approach results to be comparable (in the Internet study) or superior (in the CancerLit study) to existing information classification systems. The key future enhancement will be incorporation of better ways to identify document descriptors through syntactic and semantic front-end processing. The Kohonen-based SOM approach was considered difficult to use in all but one specialized case (the dynamic SOM created as part of the CancerLit prototype). This can probably be attributed to the fact that its associative organization does not match with the standard mental models (hierarchical and alphabetic) for information classification.

In Saudi Arabia the need is recognised significantly to move towards the concept of an Information Society, particularly for the benefit of the healthcare community. There have been some individual efforts, in this direction but they do not address the problem and related root issues. The problem is that the body and soul are not joined as one to formulate a single entity. The health professional is the body and the soul is the health information professional (health librarians). Health professionals spend a great deal of time in information searching, while the health information professional's role is underestimated. This research is conducted to explore the state of health sciences libraries, and to investigate the strengths and weaknesses of the Information Services and Information, Communication Technology (ICT) in health sciences libraries in the capital city of Saudi Arabia, Riyadh. To accomplish this, a mixed method is used (qualitative and quantitative approaches) to collect related data. A framework is designed particularly for this research and a visionary organisational model is designed initially and developed throughout the research. This proposed model is to introduce a potentially possible successful paradigm for changing the health sciences libraries environment to encounter future challenges. In addition, for this research will contribute to the better understanding of how to provide fast, efficient and easy-to-use service to increase user satisfaction. Changing the paradigm of health sciences libraries in Riyadh will facilitate better access, sharing and use of information resources from distant geographical locations, and increase participation opportunities. In addition, the proposed model considers the human and social needs of communication, and the exchange of feelings and reactions. Importantly, successful change will help healthcare environments to move towards the establishment of a flourishing health information society by popularising the use of electronic resources and demonstrating the benefits and advantages of continuous learning and development programmes. It is clear that access to fast. accurate and reliable health information and resources, may be, the difference between life and death.

Full textAbstract:
In Saudi Arabia, medical errors are at an alarming level. Lack of a Health Information Exchange (HIE) system is one the greatest reasons for medical errors in the Kingdom. Health care in many countries has evolved with the invention of electronic health information exchange system, henceforth HIE. This research paper purposes to implement HIE in Saudi Arabia, which entirely does not have a system of the sort. It is imperative instill HIE in the health care system in Saudi to allow physicians, nurses, health care facilities as well as patients to electronically share medical information in a safe and secure manner.
Many countries such as United States, New Zealand and Germany have had great success with the HIE system and have reported vast benefits. Benefits of HIE are such as reduction of health care cost as well as decreasing medical errors. For Saudi Arabia to reach the same heights, many stakeholders will be involved in the triumph of the HIE system in the Kingdom of Saudi Arabia. The biggest contributor will be the Ministry of Health, which will be in charge of implementing as well as making the system mandatory in the main four hospitals in the country: Shomasy, Kind Saud University Hospital, Ministry of interior Hospital and Ministry of Defense Hospital. Each hospital having their own current medical information recording system, will now have one universal system that is made sure to be secure and safe for patients as well as other participating organizations who have access to the HIE system.
The main concentration of the HIE system in Saudi Arabia will be in the emergency care of these four hospitals. It is crucial to have an organized and controlled way of recording as well as accessing patient medical records electronically, in a fast and effective way. This paper proposes that an HIE system in Saudi Arabia will reduce the cost of medical care and decrease medical errors. Through the use of Lean thinking and the use of quality tools, the HIE system will be able to change and increase the reliably as well as effectiveness of Urgent Care in the country and therefore have consequent benefits as well. Also, understanding who is going to play a great role in the triumph of the HIE system, such as the Ministry of Health and knowing what stakeholders will need to be affiliated and contribute will lead the project to a better success.

Full textAbstract:
This thesis examines the underlying cause of social stigma towards people living with HIV, and the extent to which it discourages HIV testing and treatment. We use a discrete choice model to describe a person’s decision to seek treatment for HIV (antiretroviral therapy or ART), and estimate the social cost of seeking treatment using administrative health records from southern Malawi. We show that seeking ART at a clinic where many other community members are present carries a significant cost, even after taking into account clinic quality and location. We investigate the theoretical effects of policy interventions designed to reduce stigma and other barriers to care, and demonstrate important complementarities between such policies. We next evaluate a cluster-randomized information experiment in Zomba, Malawi designed to correct a common misconception: most do not know that ART drugs have a public benefit, that is, the medication prevents HIV transmission between sexual partners. We microfound HIV stigma as sexual discrimination between sexual partners, and model the decision to seek an HIV test (and then, if required, medical treatment) as a signal of infection. We show, theoretically and empirically, that the randomized information intervention reduces this type of stigma and significantly increases the rate of HIV testing. The results demonstrate that social stigma is an important barrier to HIV testing and treatment, that stigma can be due to rational behavior by a misinformed public, and that providing new information can be an effective way to mitigate its effects.

The adoption rate of health information technology (HIT) remains low in developing countries, where healthcare institutions experience high operating costs and loss of revenue, which are related to systems and processes inefficiency. The purpose of this case study was to explore strategies leaders in Zimbabwe used to implement HIT. The conceptual framework of the study was Davis's technology acceptance model (TAM). Data were gathered through observations, review of organizational documents (i.e., policies, procedures, and guidelines), and in-depth interviews with a purposive sample of 10 healthcare leaders and end-users from hospitals in Zimbabwe who had successfully implemented HIT. Transcribed interview data were coded and analyzed for emerging themes. Implementation strategies, overcoming barriers to adoption, and user acceptance emerged as the themes most healthcare leaders associated with successful HIT projects. Several subthemes also emerged, including: (a) the importance of stakeholder involvement, (b) the importance of management buy-in, and (c) the low level of IT literacy among healthcare workers. The strategies identified in this study may provide a foundation on which healthcare leaders in developing countries can successfully adopt and implement HIT. The recommendations from this study could lead to positive social change by providing leaders with knowledge and skills to use information technology strategies to deliver better healthcare at lower costs while creating employment for local communities.

Full textAbstract:
Background: With Canada's aging population, increasing prevalence of chronic disease, and overburdened healthcare systems, there is a growing pressure on family caregivers to manage the care of their family members or friends. The demands of caregiving, however, can be challenging and may result in caregiver distress and an inability for caregivers to continue in their role. To help address this issue, interventions that are developed to support caregivers may contribute to greater confidence, capacity and satisfaction with their role, as well as better outcomes for their care recipient. The Internet is one area that now plays a significant role in information delivery and support services. Offering web-based support to caregivers may assist this population to provide quality care and remain in good health. In particular, online information based upon personal health and illness experiences (PHEx) could be particularly helpful for those populations, such as caregivers, that are isolated and lack support services. In order to provide optimal support and services to caregivers through web-based initiatives, a better understanding for how caregivers search for and use online health information is needed. Furthermore, it will be valuable to explore caregivers' perspectives towards online PHEx information, as this may be an especially appealing and valuable means of information delivery for this population. Methods: Three focus groups were conducted with a total of 16 people to explore how caregivers retrieve and use health information on the Internet, as well as their perspectives towards the structure, design, and content of an online PHEx website. Results: 1) In terms of how caregivers retrieve and use online health information, three broad themes were identified: searching for and choosing online health information; empowerment through use of online health information; and concerns with health information on the Internet. 2) In terms of caregivers' perspectives towards the structure, design, and content of a PHEx website, two broad themes were identified: factors important for first impressions of a PHEx website; and perceived needs and expectations for the content presented on a PHEx website. Conclusions: Caregivers offered key insights regarding online health information retrieval, usage, and other perspectives, which will be helpful for future web-based initiatives that aim to provide support to caregivers. Two conceptual frameworks are proposed related to: 1) health information website retrieval and usage, and 2) features important for a PHEx website on caregiving.Contexte: Avec la population du Canada qui vieillit, une augmentation du taux de maladies chroniques, et un système de santé surchargé, une pression se développe sur les aidants naturels pour prendre en charge les soins de leurs proches. Ces demandes peuvent être difficiles, résultant en un accumulation de stress pour les aidants et les empêchant de continuer dans leur rôle. Cependant, il existe des preuves qui suggèrent que les interventions qui supportent les aidants peuvent contribuer à augmenter leur confiance, leur capacité de travailler, leur satisfaction dans leur rôle, ainsi que de meilleurs résultats pour les proches qui bénéficient de leurs soins. De nos jours, Internet joue un rôle important dans l'acquisition d'information et dans les services de support. Il est possible que de rendre ces supports disponibles aux aidants naturels peut aider ces derniers à fournir des soins de qualité tout en restant en bonne santé. En particulier, l'information basée sur la santé personnelle et l'expérience des maladies (SPEx) est devenue particulièrement intéressante pour le public, et pourrait être utile pour les populations qui sont isolées et qui manquent de services de support, tels que les aidants naturels. Afin de fournir de meilleurs services et plus de support aux aidants naturels avec des initiatives basées sur Internet, nous devons développer une meilleure compréhension de la façon dont les aidants naturels recherchent et utilisent l'information qui se trouve sur Internet. De plus, il est utile d'explorer le point de vue des aidants naturels par rapport à l'information SPEx sur Internet, car cela peut être un moyen utile de recueillir de l'information pour eux. Méthodes: Trois groupes, avec un total de 16 participants chacun, ont été formé pour explorer de quelle façon les aidants naturels recherchent et utilisent l'information sur la santé trouvée sur l'Internet, ainsi que leurs opinions par rapport à la structure, à la disposition, et au contenu d'un site web SPEx. Résultats: 1) Trois grands thèmes ont été identifiés en relation à la façon dont les aidants naturels récupèrent et utilisent l'information sur la santé trouvée sur Internet: la recherche et le choix d'informations sur la santé; l'autonomisation grâce à l'utilisation de cette information, et les préoccupations en lien avec l'information sur la santé trouvée sur Internet. 2) Concernant les opinions des aidants naturels par rapport à la structure, la conception et le contenu d'un site web SPEx, deux grands thèmes ont été identifiés: les facteurs qui influencent les premières impressions d'un site web SPEx, et les besoins et attentes envers le contenu présenté sur un site web SPEx. Conclusions: Les aidants naturels ont fourni des renseignements importants concernant la recherche et l'utilisation d'information à propos de la santé trouvée sur Internet, ainsi que des perspectives qui seront utiles pour le dévelopement d'initiatives visant à offrir du support aux aidants naturels sur Internet. Deux suggestions sont proposées en rapport avec: 1) la recherche et l'usage de l'information a propos de la santé trouvée sur un site web; et 2) les charactéristiques importantes d'un site web sur les soins SPEx.

Appropriate e-services as well as revenue generation capabilities are key to the deployment and the sustainability for ICT installations in poor areas, particularly common in developing country. The area of e-Health is a promising area for e-services that are both important to the population in those areas and potentially of direct interest to National Health Organizations, which already spend money for Health campaigns there. This thesis focuses on the design, implementation, and full functional testing of HealthAware, an application that allows health organization to set up targeted awareness campaigns for poor areas. Requirements for such application are very specific, starting from the fact that the preparation of the campaign and its execution/consumption happen in two different environments from a technological and social point of view. Part of the research work done for this thesis was to make the above requirements explicit and then use them in the design. This phase of the research was facilitated by the fact that the thesis' work was executed within the context of the Siyakhula Living Lab (SLL; www.siyakhulaLL.org), which has accumulated multi-year experience of ICT deployment in such areas. As a result of the found requirements, HealthAware comprises two components, which are web-based, Java applications that run in a peer-to-peer fashion. The first component, the Dashboard, is used to create, manage, and publish information for conducting awareness campaigns or surveys. The second component, HealthMessenger, facilitates users' access to the campaigns or surveys that were created using the Dashboard. The HealthMessenger was designed to be hosted on TeleWeaver while the Dashboard is hosted independently of TeleWeaver and simply communicates with the HealthMessenger through webservices. TeleWeaver is an application integration platform developed within the SLL to host software applications for poor areas. Using a core service of TeleWeaver, the profile service, where all the users' defining elements are contained, campaigns and surveys can be easily and effectively targeted, for example to match specific demographics or geographic locations. Revenue generation is attained via the logging of the interactions of the target users in the communities with the applications in TeleWeaver, from which billing data is generated according to the specific contractual agreements with the National Health Organization. From a general point of view, HealthAware contributes to the concrete realizations of a bidirectional access channel between Health Organizations and users in poor communities, which not only allows the communication of appropriate content in both directions, but get 'monetized' and in so doing becomes a revenue generator.

Full textAbstract:
In the light of an ageing society with shrinking economic resources, deinstitutionalization of elderly care is a general trend. As a result, homecare is increasing, and increasingly shared between different health and social care organizations. To provide a holistic overview about the patient care process, i.e. to be patient-centred, shared homecare needs to be integrated. This requires improved support for information sharing and cooperation between different actors, such as care professionals, patients and their relatives. The research objectives of this thesis are therefore to study information and communication needs for patient-centered shared homecare, to explore how integrated information and communication technology (ICT) can support information sharing, and to analyze how current standards for continuity of care and semantic interoperability meet requirements of patient-centered shared homecare. An action research approach, characterized by an iterative cycle, an emphasis on change and close collaboration with practitioners, patients and their relatives, was used. Studying one specific homecare setting closely, intersection points between involved actors and specific needs for information sharing were identified and described as shared information objects. An integration architecture making shared information objects available through integration of existing systems was designed and implemented. Mobile virtual health record (VHR) applications thereby enable a seamless flow of information between involved actors. These applications were tested and validated in the OLD@HOME-project. Moreover, the underlying information model for a shared care plan was mapped against current standards. Some important discrepancies were identified between these results and current standards for continuity of care, stressing the importance of evaluating standardized models against requirements of evolving healthcare contexts. In conclusion, this thesis gives important insights into the needs and requirements of shared homecare, enabling a shift towards patient-centered homecare through mobile access to aggregated information from current feeder systems and documentation at the point of need.

Abstract
INFORMATION NEEDS AND INFORMATION SOURCES OF PATIENTS DIAGNOSED WITH RARE CANCERS
By Dana L. Ladd, Ph.D., MS, SLIS
BACKGROUND: Approximately 25% of all cancers diagnosed are considered rare. Patients may face many significant challenges including difficulty obtaining information about their rare conditions. Patients often have high information needs and may seek desired information from a variety of informational sources including healthcare providers, media, print, government and non-profit organizations in order to meet their needs. Accessing reliable consumer-level information can be challenging and often information needs are unmet. Dissatisfaction with health information provision can result in negative health-related outcomes and factors including decreased health-related quality of life.
METHOD: This cross-sectional design study used validated measures to assess the information needs, information sources, information satisfaction, and health-related quality of life of patients diagnosed with rare cancers (n=113). Adult patients at the VCU Health Massey Cancer Center who had been diagnosed with a rare cancer in the past 12 months were contacted via mail survey. Descriptive statistics were used to summarize patients’ information need and information received levels. Unmet needs were analyzed using a two-sample T-test. Chi-square tests were used to analyze information needs and received by demographics for gender and race and logistic regression analysis was used for age. Descriptive statistics summarized information sources used and preferred. Finally, descriptive statistics were used to summarize information satisfaction. The relationship between information satisfaction and health-related quality of life was assessed using a two-sample T-test.
RESULTS: Study participants had high information needs, particularly for information about disease, medical tests, and treatment. Though patients also reported receiving information at high levels, 21 participants (18.9%) reported being unsatisfied with information provision. Unmet needs were found for information about disease and on the item level for information about causes of cancer, whether their cancer was under control, expected benefits of treatment, and financial, insurance, and work-related information. Although participants reported preferring information from their healthcare providers, they most commonly sought information from the Internet more than any other source.
CONCLUSION: By identifying patients’ information needs and sources, this study fills an important gap in the information needs and sources literature of patients diagnosed with rare cancers. Identification of these needs allows healthcare providers to tailor information provision to more effectively meet patients’ information needs.
