Patient involvement in quality improvement in primary health care

Van Deventer, Claire January 2016 (has links)
A Thesis submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy December 2015 Johannesburg. / Introduction There has been little published in South Africa regarding quality improvement in health and in particular the involvement of patients in this intervention. There is evidence globally that both quality improvement efforts and particularly the engagement of the users adds value to health services. Three projects were conceived around this core concept as explained below. 1. Systematic review. Patients’ involvement in improvement initiatives: a qualitative systematic review After a search was done of databases, 5121 papers were found to be potentially relevant. After screening and critical appraisal for eligibility, it was found that 31 articles qualified for analysis. These were then assessed using JBI software and 5 categories and 2 metasynthesised findings were documented. In summary, there were enablers and barriers to involving patients. The five categories which lead to these 2 findings were the following: (1) although patient participation in QI is acknowledged and encouraged by many policies and documents globally, it is difficult to implement; (2) there are differing views between patients and providers as to the process; (3) on the positive side, different levels of involvement of patients in QI were demonstrated; 4) practical, appropriate and innovative results emerged; (5) individual or group support and incremental development through skills and enablement contributed towards success 2. The Integration of Non Communicable Chronic Diseases (NCDs) and HIV/Aids and mental health care through the involvement of chronically ill patients using Empowerment Evaluation (EE). At 9 primary care clinics, the process of EE was followed with chronically ill stable patients and appropriate healthcare workers. This was an additional intervention in an ongoing QI cycle on the integration of all chronic illnesses into one model, based on Lean principles. Steps followed were ‘’taking stock’’ ie assessing patients’ and HCWs’ impressions of the services at the clinic in a measured way, creating a vision and using this as a yardstick for the project and then problems and solutions being co-managed by the collaborative team. A total of 37 interventions were discussed and 23 implemented in the time frame. Innovative solutions were implemented and teams were empowered by the potential they experienced. 3. An exploration of childhood nutrition and wellness in a subdistrict by patient inclusivity in QI using experience based codesign (EBCD) with mothers/caregivers of malnourished children . Following the steps of EBCD, staff and patients exposed to health services regarding ill children, were interviewed, feedback was given of the findings separately and then in a combined meeting and co-design teams were created to work with the prioritised quality improvement interventions. Touch points in the system were examined through emotional mapping, video interviews and observations. Within the 10 month period of the project, 38 interventions were identified and 25 accepted and implemented at different levels. Conclusion The methodologies were chosen to fit with the qualitative aspect of the research. There were concrete appropriate improvement outcomes due to the engagement of service users in both the primary care clinics serving chronically ill patients and the paediatric system in one subdistrict eg the flow of patients improved, logistical improvements like direct admissions for very ill children, school and library opportunities for admitted ill children etc occurred. Subjective gains like the acknowledgement of their power role by patients and a flattening of the healthcare worker hierarchy were also experienced in the research. Other findings were that unexpected roleplayers were identified, the timeframe of such QI cycles needs to be considered especially regarding the resilience of patients and resources were not an importatn limitation. However some modifications would have to be considered to make these research approaches common practice. The particular research methodologies have not been published in a South African context before and have also not been used for paediatric or integrated chronic illness research and therefore contribute both content and process information to health systems research in South Africa. / MT2017

Bioética e pesquisa: percepção dos sujeitos de pesquisa acerca de assuntos e situações constrangedoras em pesquisas com questionamentos / Bioethics and research: perception of research subjects about embarrassing topics and situations in research with polls.

Pessalacia, Juliana Dias Reis 15 April 2009 (has links)
A valorização dos limites éticos, no que diz respeito à abordagem às pessoas, em pesquisas em que utilizem instrumentos contendo questionamentos é pouco considerada. Pensa-se que o risco para os participantes é quase nulo, uma vez que a utilização de tais instrumentos não envolve danos físicos. Deste modo, parece não estar muito clara para os pesquisadores a importância da reflexão sobre estes tipos de instrumentos de coleta de dados como possíveis geradores de riscos de ordem não-física (psicológicos, morais, sociais, espirituais). Assim sendo, este estudo teve como objetivo reconhecer os tipos de assuntos/questões que possam trazer algum tipo de constrangimento ou mesmo danos a sujeitos de pesquisa vulneráveis (ou não) circunstancialmente. Tratou-se de um estudo prospectivo, comparativo, de abordagem quantitativa onde foram abordados ao todo 1149 sujeitos de pesquisa subdivididos em população vulnerável e não vulnerável circunstancialmente. Tais populações foram convidadas a participar do estudo atribuindo graus de constrangimento relacionado a tópicos de sensibilidade e a situações possivelmente constrangedoras em pesquisa. Foram levantados como assuntos potencialmente constrangedores, falar sobre: traição, violência física, provocação sexual no trabalho, abuso sexual, violência psicológica, morte de pessoas próximas e questões envolvendo a sexualidade e o comportamento amoroso. Contudo, chamanos a atenção, como resultado, o fato de que o constrangimento aumenta se consideradas as condições nas quais tais assuntos são abordados, foram citadas: a falta de autorização/consentimento, a falta de esclarecimento prévio acerca do tipo de questões a serem abordadas, a questão do sigilo e anonimato e o uso de imagens ou gravador. Tais resultados trazem subsídios importantes para a avaliação ética por parte de pesquisadores e de Comitês de Ética em Pesquisa com Seres Humanos, no que diz respeito à prevenção de riscos em pesquisas com questionamentos. / The importance of ethical limits concerning the approaching of subjects in research that use poll instruments is not much considered. People think that the risk for the participants is almost null, assuming that such instruments do not cause any physical damages. This way, the importance of this reflection seems not to be very clear for the investigators using these types of instruments of data collection as possible creators of non-physical risks such as psychological, moral, social and spiritual. Thus, this study aimed at recognizing the types of subjects/questions that could bring some types of embarrassment or even damages to vulnerable (or not) subjects of research, eventually. This was a prospective, comparative, quantitative approach which addressed 1149 subjects of research subdivided into vulnerable and not vulnerable population, circumstantially. These people were invited to participate in the study giving a degree of embarrassment related to sensitive topics and possibly embarrassing situations in research. Issues were raised as potentially embarrassing, such as: betrayal, physical violence, sexual bullying at work, sexual abuse, psychological abuse and death of close people, questions involving sexuality and loving behavior issues. However, it calls us the attention, as a result, to the fact that the embarrassment may increase if considered the conditions under which such topics are approached, such as: the lack of authorization/consent, the lack of prior information about the type of questions to be addressed, the issue of confidentiality and anonymity and the use of images or recorder. These results provide important subsidies for the ethical evaluation by researchers and Research Ethics Committees involving human beings, regarding the prevention of risks in studies with polls.

Simulation study on the validity of methods for detecting publication bias in meta-analysis for binary outcomes. / CUHK electronic theses & dissertations collection

January 2006 (has links)
Conclusions. The sensitivity and positive predictive value are generally more concerned than the specificity and negative predictive value in assessing and adjusting publication bias in meta-analyses. In this sense, Egger's regression can be recommended for its high sensitivity, while any positive result from Tang's method would suggest a probability of bias that should be taken seriously. Given the different patterns of the accuracy with the OR and the P1-P2 combination, a combination of Egger's regression and Tang's regression would be advisable. Further studies are needed to study the accuracy of methods used in combination. / Due to sampling error and true heterogeneity, a single study cannot provide a comprehensive picture and a precise estimate of, say the effectiveness of a treatment. Systematic reviews that identify and integrate relevant studies have become the most important scientific, quantitative method to summarize scientific research. Meta-analysis is the statistical method used in systematic reviews to combine results from individual studies. / However, due to selective submission and publication, not all relevant studies conducted, especially those unpublished studies with an insignificant negative result, are easily accessible to those who conduct reviews. As a result, the truth, say, the effect of a treatment, would be overestimated. This phenomenon is known as publication bias. A few methods for detecting the bias have been developed and used in meta-analyses. Although their accuracy has been studied, some important issues remain to be answered, such as when would a method be good enough for practical use and is it similarly good for different definitions of the odds ratio? / Methods. We conducted a simulation study to examine the accuracy of four commonly used bias-detection methods with various ORs and P1-P2 combinations. In a simulation study, the true bias status can be predetermined and thus be compared with the results of the bias-detection methods. The four methods are Egger's regression, funnel plot regression, rank correlation regression, and Tang's regression. Realistic sample size was used for simulating individual studies and the numbers of studies in a meta-analysis was also varied. Both the sensitivity and specificity are examined against the magnitude of the OR and the P1-P 2 combination to identify the ORs and P1-P 2 combinations for which a method is sufficiently accurate. Predictive values are also examined for the same reason and in the same manner. / Results. The sensitivity and positive predictive value are generally low and in particular when the OR is close to one for which publication bias is of a particular concern. Egger's regression has the highest sensitivity among the four, in particular when the OR is neither close to one nor exceptionally large or small. Due to the relatively lower specificity, the positive predictive value of Egger's regression is not as high as that for Tang's regression and funnel plot regression. Tang's regression and funnel plot regression are very similar in sensitivity, specificity and predictive values, with the former being slightly better. Rank correlation seems the least accurate method overall. Tang's regression has in general the highest positive predictive value among the four methods in particular when the OR is below one. / Chung Chi-keung. / "June 2006." / Adviser: Tang Jin Ling. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1588. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 116-124). / Electronic reproduction.

Characterising the relationship between practice and laboratory-based studies of designers for critical design situations

Cash, Philip January 2012 (has links)
Experimental study of the designer plays a critical role in design research. However laboratory based study is often poorly compared and contrasted to practice, leading to a lack of uptake and subsequent research impact. The importance of addressing this issue is highlighted by its significant influence on design research and many related fields. As such the main aim of this work is to improve empirical design research by characterising the relationship between practice and laboratory-based studies for critical design situations. A review of the state of the art methods in design research and key related fields is reported. This highlights the importance and commonality of a set or core issues connected to the failure to effectively link study of practice and study in the laboratory. Further to this a technical review and scoping was carried out to establish the most efective capture strategy to be used when studying the designer empirically. Subsequently three studies are reported, forming a three point comparison between practice the laboratory (with student practitioners) and an intermediary case (a laboratory with practitioners) . Results from these studies contextualise the critical situations in practice and develop a detailed multi-level comparison between practice and the laboratory which was then validated with respect to a number of existing studies. The primary contribution of this thesis is the development of a detailed multi-level relationship between practice and the laboratory for critical design situations: information seeking, ideation and design review. The second key contribution is the development of a generic method for the empirical study of designers in varying contexts - allowing researchers to build on this work and more effectively link diverse studies together. The final key contribution of this work is the identification of a number of core methodological issues and mitigating techniques affecting both design research and its related fields.

Working together: two qualitative approaches to researching writing support for doctoral students

Aldrich, Carrie 01 August 2018 (has links)
This dissertation addresses two problems with advanced academic writing pedagogy. First, doctoral students must participate in academic discourse communities, yet they report being underprepared to do so (Boquet et al., 2015; Caplan & Cox, 2016). Second, studies (e.g., Curry & Lillis, 2004; Matsuda & Tardy, 2007; Tardy & Matsuda, 2009) suggest that L1 and L2 voices are not well integrated in the institution and that this lack of integration systemically privileges the dominant culture. The purpose of this research is to investigate the role relationships play in helping culturally and linguistically diverse doctoral students negotiate and acquire advanced academic discourse. I pose the overarching research question: Given a discipline-specific writing center for graduate students in a College of Education, what role does interaction play in helping students to participate in academic conversations? The two papers in this collection employ qualitative classification and discourse analysis to investigate writing-related interactions among peers. Data include audio-recorded writing consultations and interviews, post-session reports, field notes, and artifacts. Taken together, findings from this research highlight the role interaction can play in writing support, development, and research. This research has implications for developing writing pedagogy and support programs to facilitate productive academic socialization. In response, the researcher calls for more robust academic writing support in order to improve access and resources for diverse student populations and decrease attrition and time to degree for all students.

Moonlight in Miami: A Field Study of Human-Robot Interaction in the Context of an Urban Search and Rescue Disaster Response Training Exercise

Burke, Jennifer L 08 September 2004 (has links)
This study explores human-robot interaction during a 16-hour high-fidelity Urban Search and Rescue (USAR) disaster response drill with teleoperated robots. Situation awareness and team interaction were examined using communication analysis. Operators (n=5) sought assistance from team members to compensate for difficulties building or maintaining situation awareness. Operator-team member communication focused on relating what was seen through the robot's eye view with prior knowledge and planning search strategies. Results suggest operators need a new cognitive mental model to filter and comprehend data provided by the robot, and that robot-assisted search is a team task rather than an individual one. USAR technical search teams need a new shared mental model of robot-assisted search in order to coordinate activities effectively.

"I know where you can find out more": The role of peer educators in promoting quality use of medicines among seniors

Klein, Linda Ann, Public Health & Community Medicine, Faculty of Medicine, UNSW January 2008 (has links)
Improving the quality use of medicines (QUM) among seniors, particularly those using multiple medicines, is a national priority. The National Prescribing Service??s Seniors QUM Program was developed in collaboration with consumers to address seniors?? medicines information needs. Seniors are trained as peer educators to convey QUM messages to other seniors in a single group session. However, there is a dearth of research assessing peer education for seniors about medicines, and little understanding of what peer educators do in practice. This research investigated how peer educators empower seniors toward the quality use of their medicines. A participatory action research inquiry was undertaken nationally with organisational leaders and locally with peer educators. The design was a nested case study with multiple sites, where the Seniors Program was the overarching case containing eight disparate local sites. The participatory inquiry engaged peer educators from each local site. Qualitative data were collected through participant observation and interviews. Data were analysed using grounded theory methods and findings were triangulated with other data sources. Peer educators demonstrated five main functions in the program ?? one primary function within QUM sessions and four support functions outside of sessions. The primary function of facilitating peer learning comprised 10 elements. A model depicts these elements in the context of varying session conditions and consequences. Educators?? lived experience as seniors and lay persons was an overarching contributor to peer learning, used strategically through storytelling to assist other elements. Sharing QUM outside of sessions occurred frequently, but requires development to reach isolated seniors. Peer educators exceeded expectations in getting QUM messages to seniors, applying unique skills to the information exchange within sessions. Their status as lay persons tackling the complex topic of QUM reflected an understanding of the disempowerment seniors may feel when seeking information about medicines. Peer educators?? ability to model an active partner role by applying their lived experience through storytelling in an interactive, mutually sharing session challenged seniors to rethink their medicines management and interactions with health professionals. As the population ages and medicines use increases, understanding and using seniors effectively as educators has great potential.
