- ItemAdvancing research integrity : a programme to embed good practice in Africa(Pan African Medical Journal, 2019-08-13) Rohwer, Anke; Wager, Elizabeth; Young, TarynIn Africa, training programmes as well as institutional policies on research integrity are lacking. Institutions have a responsibility to oversee research integrity through various efforts, including policies and training. We developed, implemented and evaluated an institutional approach to promote research integrity at African institutions, comprising a workshop for researchers ("bottom-up") and discussions with senior faculty on institutional policies ("top-down"). During the first day, we facilitated a workshop to introduce research integrity and promote best practices with regards to authorship, plagiarism, redundant publication and conflicts of interest. We used a variety of interactive teaching approaches to facilitate learning, including individual and group activities, small group discussions and case-based learning. We met with senior faculty on the following day to provide feedback and insights from the workshop, review current institutional policies and provide examples of what other research groups are doing. We evaluated the process. Participants actively engaged in discussions, recognised the importance of the topic and acknowledged that poor practices occurred at their institution. Discussions with senior researchers resulted in the establishment of a working group tasked with developing a publication policy for the institution. Our approach kick-started conversations on research integrity at institutions. There is a need for continued discussions, integrated training programmes and implementation of institutional policies and guidelines to promote good practices.
- ItemAn approach for setting evidence-based and stakeholder-informed research priorities in low- and middle-income countries(World Health Organization, 2016) Rehfuess, Eva A.; Durao, Solange; Kyamanywa, Patrick; Meerpohl, Joerg J.; Young, Taryn; Rohwer, Anke; The Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+)ENGLISH SUMMARY : To derive evidence-based and stakeholder-informed research priorities for implementation in African settings, the international research consortium Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) developed and applied a pragmatic approach. First, an online survey and face-to-face consultation between CEBHA+ partners and policy-makers generated priority research areas. Second, evidence maps for these priority research areas identified gaps and related priority research questions. Finally, study protocols were developed for inclusion within a grant proposal. Policy and practice representatives were involved throughout the process. Tuberculosis, diabetes, hypertension and road traffic injuries were selected as priority research areas. Evidence maps covered screening and models of care for diabetes and hypertension, population-level prevention of diabetes and hypertension and their risk factors, and prevention and management of road traffic injuries. Analysis of these maps yielded three priority research questions on hypertension and diabetes and one on road traffic injuries. The four resulting study protocols employ a broad range of primary and secondary research methods; a fifth promotes an integrated methodological approach across all research activities. The CEBHA+ approach, in particular evidence mapping, helped to formulate research questions and study protocols that would be owned by African partners, fill gaps in the evidence base, address policy and practice needs and be feasible given the existing research infrastructure and expertise. The consortium believes that the continuous involvement of decision-makers throughout the research process is an important means of ensuring that studies are relevant to the African context and that findings are rapidly implemented.
- ItemAuthorship, plagiarism and conflict of interest : views and practices from low/ middle-income country health researchers(BMJ Publishing Group, 2017-11) Rohwer, Anke; Young, Taryn; Wager, Elizabeth; Garner, PaulObjectives To document low/middle-income country (LMIC) health researchers’ views about authorship, redundant publication, plagiarism and conflicts of interest and how common poor practice was in their institutions. Design We developed a questionnaire based on scenarios about authorship, redundant publication, plagiarism and conflicts of interest. We asked participants whether the described practices were acceptable and whether these behaviours were common at their institutions. We conducted in-depth interviews with respondents who agreed to be interviewed. Participants We invited 607 corresponding authors of Cochrane reviews working in LMICs. From the 583 emails delivered, we obtained 199 responses (34%). We carried out in-depth interviews with 15 respondents. Results Seventy-seven per cent reported that guest authorship occurred at their institution, 60% reported text recycling. For plagiarism, 12% of respondents reported that this occurred ‘occasionally’, and 24% ‘rarely’. Forty per cent indicated that their colleagues had not declared conflicts of interest in the past. Respondents generally recognised poor practice in scenarios but reported that they occurred at their institutions. Themes identified from in-depth interviews were (1) authorship rules are simple in theory, but not consistently applied; (2) academic status and power underpin behaviours; (3) institutions and culture fuel bad practices and (4) researchers are uncertain about what conflict of interests means and how this may influence research. Conclusions LMIC researchers report that guest authorship is widely accepted and common. While respondents report that plagiarism and undeclared conflicts of interest are unacceptable in practice, they appear common. Determinants of poor practice relate to academic status and power, fuelled by institutional norms and culture.
- ItemBeing HIV positive and staying on antiretroviral therapy in Africa : a qualitative systematic review and theoretical model(PLoS, 2019-01-10) Eshun-Wilson, Ingrid; Rohwer, Anke; Hendricks, Lynne; Oliver, Sandy; Garner, PaulBackground : Adherence to antiretroviral therapy (ART) and long-term uninterrupted engagement in HIV care is difficult for HIV-positive people, and randomized trials of specific techniques to promote adherence often show small or negligible effects. Understanding what influences decision-making in HIV-positive people in Africa may help researchers and policy makers in the development of broader, more effective interventions and policies. Methods: We used thematic synthesis and a grounded theory approach to generate a detailed narrative and theoretical model reflecting life with HIV in Africa, and how this influences ART adherence and engagement decisions. We included qualitative primary studies that explored perspectives, perceptions and experiences of HIV-positive people, caregivers and healthcare service providers. We searched databases from 1 January 2013 to 9 December 2016, screened all studies, and selected those for inclusion using purposeful sampling methods. Included studies were coded with Atlas.ti, and we assessed methodological quality across five domains. Results: We included 59 studies from Africa in the synthesis. Nine themes emerged which we grouped under three main headings. First, people who are HIV-positive live in a complicated world where they must navigate the challenges presented by poverty, competing priorities, unpredictable life events, social identity, gender norms, stigma, and medical pluralism—these influences can make initiating and maintaining ART difficult. Second, the health system is generally seen as punishing and uninviting and this can drive HIV-positive people out of care. Third, long-term engagement and adherence requires adaptation and incorporation of ART into daily life, a process which is facilitated by: inherent self-efficacy, social responsibilities, previous HIV-related illnesses and emotional, practical or financial support. These factors together can lead to a “tipping point”, a point in time when patients choose to either engage or disengage from care. HIV-positive people may cycle in and out of these care states in response to fluctuations in influences over time. Conclusion: This analysis provides a practical theory, arising from thematic synthesis of research, to help understand the dynamics of adherence to ART and engagement in HIV care. This can contribute to the design of service delivery approaches, and informed thinking and action on the part of policy makers, providers, and society: to understand what it is to be HIV-positive in Africa and how attitudes and the health service need to shift to help those with HIV lead ‘normal’ lives.
- ItemEffective or just practical? : an evaluation of an online postgraduate module on evidence-based medicine (EBM)(BioMed Central, 2013-05) Rohwer, Anke; Young, Taryn; Van Schalkwyk, SusanTeaching the steps of evidence-based medicine (EBM) to undergraduate as well as postgraduate health care professionals is crucial for implementation of effective, beneficial health care practices and abandonment of ineffective, harmful ones. Stellenbosch University in Cape Town, South Africa, offers a 12-week, completely online module on EBM within the Family Medicine division, to medical specialists in their first year of training. The aim of this study was to formatively evaluate this module; assessing both the mode of delivery; as well as the perceived effectiveness and usefulness thereof. Methods We used mixed methods to evaluate this module: A document review to assess whether the content of the module reflects important EBM competencies; a survey of the students to determine their experiences of the module; and semi-structured interviews with the tutors to explore their perspectives of the module. Ethics approval was obtained. Results The document review indicated that EBM competencies were covered adequately, although critical appraisal only focused on randomised controlled trials and guidelines. Students had a positive attitude towards the module, but felt that they needed more support from the tutors. Tutors felt that students engaged actively in discussions, but experienced difficulties with understanding certain concepts of EBM. Furthermore, they felt that it was challenging explaining these via the online learning platform and saw the need to incorporate more advanced technology to better connect with the students. In their view the key to successful learning of EBM was to keep it relevant and applicable to everyday practice. Tutors also felt that an online module on EBM was advantageous, since doctors from all over the world were able to participate. Conclusion Our study has shown that the online module on EBM was effective in increasing EBM knowledge and skills of postgraduate students and was well received by both students and tutors. Students and tutors experienced generic challenges that accompany any educational intervention of EBM (e.g. understanding difficult concepts), but in addition had to deal with challenges unique to the online learning environment. Teachers of EBM should acknowledge these so as to enhance and successfully implement EBM teaching and learning for all students.
- ItemEvidence synthesis workshops : moving from face-to-face to online learning(BMJ Publishing, 2021-10) McCaul, Michael; Durao, Solange; Kredo, Tamara; Garner, Paul; Young, Taryn; Rohwer, AnkePostgraduate training is moving from face-to-face workshops or courses to online learning to help increase access to knowledge, expertise and skills, and save the cost of face-to-face training. However, moving from face-to-face to online learning for many of us academics is intimidating, and appears even more difficult without the help of a team of technologists. In this paper, we describe our approach, our experiences and the lessons we learnt from converting a Primer in Systematic Reviews face-to-face workshop to a 6-week online course designed for healthcare professionals in Africa. We learnt that the team needs a balance of skills and experience, including technical know-how and content knowledge; that the learning strategies needed to achieve the learning objectives must match the content delivery. The online approach should result in both building knowledge and developing skills, and include interactive and participatory approaches. Finally, the design and delivery needs to keep in mind the limited and expensive internet access in some resource-poor settings in Africa.
- ItemIntegrated knowledge translation to advance noncommunicable disease policy and practice in South Africa : application of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework(BioMed Central, 2021-05-17) Jessani, Nasreen S.; Rohwer, Anke; Schmidt, Bey-Marrie; Delobelle, PeterBackground: In response to the “know–do” gap, several initiatives have been implemented to enhance evidenceinformed decision-making (EIDM). These include individual training, organizational culture change management, and legislative changes. The importance of relationships and stakeholder engagement in EIDM has led to an evolution of models and approaches including integrated knowledge translation (IKT). IKT has emerged as a key strategy for ensuring that engagement is equitable, demand-driven, and responsive. As a result, the African-German Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) incorporated an IKT approach to influence noncommunicable diseases (NCD) policy and practice. We documented the phased process of developing, implementing, and monitoring the IKT approach in South Africa; and explored the appropriateness of using the exploration, preparation, implementation, and sustainment (EPIS) framework for this purpose. Methods: We mapped the South Africa IKT approach onto the EPIS framework using a framework analysis approach. Notes of team meetings, stakeholder matrices, and engagement strategies were analysed and purposefully plotted against the four phases of the framework in order to populate the different constructs. We discussed and finalized the analysis in a series of online iterations until consensus was reached. Results: The mapping exercise revealed an IKT approach that was much more iterative, dynamic, and engaging than initially thought. Several constructs (phase-agnostic) remained important and stable across EPIS phases: stable and supportive funding; committed and competent leadership; skilled and dedicated IKT champions; diverse and established personal networks; a conducive and enabling policy environment; and boundary-spanning intermediaries. Constructs such as “innovations” constantly evolved and adapted to the changing inner and outer contexts (phase-specific). Conclusions: Using the EPIS framework to interrogate, reflect on, and document our IKT experiences proved extremely relevant and useful. Phase-agnostic constructs proved critical to ensure resilience and agility of NCD deliberations and policies in the face of highly dynamic and changing local contexts, particularly in view of the current coronavirus disease 2019 (COVID-19) pandemic. Bridging IKT with a framework from implementation science helps to reflect on this process and can guide the development and planning of similar interventions and strategies.
- ItemIntegrated models of care for diabetes and hypertension in low- and middle-income countries (LMICs) : protocol for a systematic review(BMC (part of Springer Nature), 2018) Nicol, Jeannine Uwimana; Rohwer, Anke; Young, Taryn; Bavuma, Charlotte M.; Meerphol, Joerg J.Background: In low- and middle-income countries (LMICs), the burden of non-communicable diseases (NCDs) is growing against an existing burden of other diseases such as HIV/AIDS. Integrated models of care can help address the rising burden of multi-morbidity. Although integration of care can occur at various levels and has been defined in numerous ways, our aim is to assess the effects of integration of service delivery at primary healthcare level in LMICs. Methods: We will consider randomised controlled trials (RCTs), cluster RCTs, non-randomised trials, controlled beforeafter studies and interrupted time series that examine integrated models of care among people with multi-morbidities, of which diabetes or hypertension is one, living in LMICs. We will compare fully integrated models of care to standalone care, partially integrated models of care to stand-alone care and fully integrated models to partially integrated models of care. Primary outcomes include all-cause mortality, disease-specific morbidity, HbA1c, systolic blood pressure and cholesterol levels. Secondary outcomes include access to care, retention in care, adherence, continuity of care, quality of care and cost of care. We will conduct a comprehensive search in the following databases: MEDLINE, EMBASE, the Cochrane Central Register of Control Trials, LILACS, Africa-Wide Information, CINAHL and Web of Science. In addition, we will search trial registries, relevant conference abstracts and check references lists of included studies. Selection of studies, data extraction and assessment of risk of bias will be performed independently by two review authors. We will resolve discrepancies through discussion with a third author. We will contact study authors in case of missing data. If included studies are sufficiently homogenous, we will pool results in a meta-analysis. Clinical heterogeneity related to the population, intervention, outcomes and context will be documented in table format and explored through subgroup analysis. We will assess χ²and I² tests for statistical heterogeneity. We will use GRADE to make judgements about the certainty of evidence and present findings in a summary of findings table. Discussion: In light of limited evidence on the provision of comprehensive care for diabetes and hypertension, and its comorbidity in LMCIs, we believe that the findings of this systematic review will provide a synthesis of evidence on effective models of integrated care for diabetes and hypertension and their comorbidities at primary healthcare level. This will enable policy-makers to device policies and programs that are evidence informed.
- ItemIntegration of care for hypertension and diabetes : a scoping review assessing the evidence from systematic reviews and evaluating reporting(BioMed Central, 2018-06-20) Yiu, Kristy C.; Rohwer, Anke; Young, TarynBackground: With the rise in premature mortality rate from non-communicable disease (NCD), there is a need for evidence-based interventions. We evaluated existing systematic reviews on effectiveness of integration of healthcare services, in particular with focus on delivery of care designed to improve health and process outcomes in people with multi-morbidity, where at least one of the conditions was diabetes or hypertension. Methods: We searched MEDLINE, EMBASE, Cochrane Library, and Health Evidence to November 8, 2016 and consulted experts. One review author screened titles, abstracts and two review authors independently screened short listed full-texts and selected reviews for inclusion. We considered systematic reviews evaluating integration of care, compared to usual care, for people with multi-morbidity. One review author extracted data and another author verified it. Two review authors independently evaluated risk of bias using ROBIS and AMSTAR. Inter-rater reliability was analysed for ROBIS and AMSTAR using Cohen’s kappa and percent agreement. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was used to assess reporting. Results: We identified five systematic reviews on integration of care. Four reviews focused on comorbid diabetes and depression and two covered hypertension and comorbidities of cardiovascular disease, depression, or diabetes. Interventions were poorly described. The health outcomes evaluated included risk of all-cause mortality, measures of depression, cholesterol levels, HbA1c levels, effect of depression on HbA1c levels, symptom improvement, systolic blood pressure, and hypertension control. Process outcomes included access and utilisation of healthcare services, costs, and quality of care. Overall, three reviews had a low and medium risk of bias according to ROBIS and AMSTAR respectively, while two reviews had high risk of bias as judged by both ROBIS and AMSTAR. Findings have demonstrated that collaborative care in general resulted in better health and process outcomes when compared to usual care for both depression and diabetes and hypertension and diabetes. Conclusions: Several knowledge gaps were identified on integration of care for comorbidities with diabetes and/or hypertension: limited research on this topic for hypertension, limited reviews that included primary studies based in low-middle income countries, and limited reviews on collaborative care for communicable and NCDs.
- ItemA mega-aggregation framework synthesis of the barriers and facilitators to linkage, adherence to ART and retention in care among people living with HIV(BMC, 2021) Hendricks, Lynn; Eshun-Wilson, Ingrid; Rohwer, AnkeBackground: People living with human immunodeficiency virus (PLHIV) struggle with the challenges of living with a chronic disease and integrating antiretroviral treatment (ART) and care into their daily lives. The aims of this study were as follows: (1) to undertake the first mega-aggregation of qualitative evidence syntheses using the methods of framework synthesis and (2) make sense of existing qualitative evidence syntheses that explore the barriers and facilitators of adherence to antiretroviral treatment, linkage to care and retention in care for PLHIV to identify research gaps. Methods: We conducted a comprehensive search and did all screening, data extraction and critical appraisal independently and in duplicate. We used the Kaufman HIV Behaviour Change model (Kaufman et al., 2014) as a framework to synthesise the findings using the mega-aggregative framework synthesis approach, which consists of 8 steps: (1) identify a clearly defined review question and objectives, (2) identify a theoretical framework or model, (3) decide on criteria for considering reviews for inclusion, (4) conduct searching and screening, (5) conduct quality appraisal of the included studies, (6) data extraction and categorisation, (7) present and synthesise the findings, and (8) transparent reporting. We evaluated systematic reviews up to July 2018 and assessed methodological quality, across reviews, using the Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews. Results: We included 33 systematic reviews from low, middle- and high-income countries, which reported on 1, 111,964 PLHIV. The methodological quality of included reviews varied considerably. We identified 544 unique thirdorder concepts from the included systematic reviews, which were reclassified into 45 fourth-order themes within the individual, interpersonal, community, institutional and structural levels of the Kaufman HIV Behaviour Change model. We found that the main influencers of linkage, adherence and retention behaviours were psychosocial and personal characteristics—perceptions of ART, desires, fears, experiences of HIV and ART, coping strategies and mental health issues—interwoven with other factors on the interpersonal, community, institutional and structural level. Using this approach, we found interdependence between factors influencing ART linkage, retention and adherence and identified the need for qualitative evidence that explores, in greater depth, the complex relationships between structural factors and adherence, sociodemographic factors such as community violence and retention, and the experiences of growing up with HIV in low- and middle-income countries—specifically in children, youth, women and key populations. Conclusions: This is the first mega-aggregation framework synthesis, or synthesis of qualitative evidence syntheses using the methods of framework synthesis at the overview level. We found the novel method to be a transparent and efficient method for assessing the quality and making sense of existing qualitative systematic reviews.
- ItemMethods used and lessons learnt in conducting document reviews of medical and allied health curricula : a key step in curriculum evaluation(BioMed Central, 2014-11) Rohwer, Anke; Schoonees, Anel; Young, TarynBackground: This paper describes the process, our experience and the lessons learnt in doing document reviews of health science curricula. Since we could not find relevant literature to guide us on how to approach these reviews, we feel that sharing our experience would benefit researchers embarking on similar projects. Methods: We followed a rigorous, transparent, pre-specified approach that included the preparation of a protocol, a pre-piloted data extraction form and coding schedule. Data were extracted, analysed and synthesised. Quality checks were included at all stages of the process. Results: The main lessons we learnt related to time and project management, continuous quality assurance, selecting the software that meets the needs of the project, involving experts as needed and disseminating the findings to relevant stakeholders. Conclusion: A complete curriculum evaluation comprises, apart from a document review, interviews with students and lecturers to assess the learnt and taught curricula respectively. Rigorous methods must be used to ensure an objective assessment.
- ItemMixed method evaluation of the CEBHA+ integrated knowledge translation approach : a protocol(BioMed Central, 2021-01-18) Pfadenhauer, Lisa M.; Grath, Tanja; Delobelle, Peter; Jessani, Nasreen; Meerpohl, Joerg J.; Rohwer, Anke; Schmidt, Bey-Marrie; Toews, Ingrid; Akiteng, Ann R.; Chapotera, Gertrude; Kredo, Tamara; Levitt, Naomi; Ntawuyirushintege, Seleman; Sell, Kerstin; Rehfuess, Eva A.Background: The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA+) is a research consortium concerned with the prevention, diagnosis and treatment of non-communicable diseases. CEBHA+ seeks to engage policymakers and practitioners throughout the research process in order to build lasting relationships, enhance evidence uptake, and create long-term capacity among partner institutions in Ethiopia, Malawi, Rwanda, South Africa and Uganda in collaboration with two German universities. This integrated knowledge translation (IKT) approach includes the formal development, implementation and evaluation of country specific IKT strategies. Methods: We have conceptualised the CEBHA+ IKT approach as a complex intervention in a complex system. We will employ a comparative case study (CCS) design and mixed methods to facilitate an in-depth evaluation. We will use quantitative surveys, qualitative interviews, quarterly updates, and a policy document analysis to capture the process and outcomes of IKT across the African CEBHA+ partner sites. We will conduct an early stage (early 2020) and a late-stage evaluation (early 2022), triangulate the data collected with various methods at each site and subsequently compare our findings across the five sites. Discussion: Evaluating a complex intervention such as the CEBHA+ IKT approach is complicated, even more so when undertaken across five diverse countries. Despite conceptual, methodological and practical challenges, our comparative case study addresses important evidence gaps: While involving decision-makers in the research process is gaining traction worldwide, we still know very little regarding (i) whether this approach really makes a difference to evidence uptake, (ii) the mechanisms that make IKT successful, and (iii) relevant differences across socio-cultural contexts. The evaluation described here is intended to provide relevant insights on all of these aspects, notably in countries in Sub-Saharan Africa, and is expected to contribute to the science of IKT overall.
- ItemPatience, persistence and pragmatism : experiences and lessons learnt from the implementation of clinically integrated teaching and learning of evidence-based health care – a qualitative study(Public Library of Science, 2015-06) Young, Taryn; Rohwer, Anke; Van Schalkwyk, Susan; Volmink, Jimmy; Clarke, MikeBackground: Clinically integrated teaching and learning are regarded as the best options for improving evidence-based healthcare (EBHC) knowledge, skills and attitudes. To inform implementation of such strategies, we assessed experiences and opinions on lessons learnt of those involved in such programmes. Methods and Findings: We conducted semi-structured interviews with 24 EBHC programme coordinators from around the world, selected through purposive sampling. Following data transcription, a multidisciplinary group of investigators carried out analysis and data interpretation, using thematic content analysis. Successful implementation of clinically integrated teaching and learning of EBHC takes much time. Student learning needs to start in pre-clinical years with consolidation, application and assessment following in clinical years. Learning is supported through partnerships between various types of staff including the core EBHC team, clinical lecturers and clinicians working in the clinical setting. While full integration of EBHC learning into all clinical rotations is considered necessary, this was not always achieved. Critical success factors were pragmatism and readiness to use opportunities for engagement and including EBHC learning in the curriculum; patience; and a critical mass of the right teachers who have EBHC knowledge and skills and are confident in facilitating learning. Role modelling of EBHC within the clinical setting emerged as an important facilitator. The institutional context exerts an important influence; with faculty buy-in, endorsement by institutional leaders, and an EBHC-friendly culture, together with a supportive community of practice, all acting as key enablers. The most common challenges identified were lack of teaching time within the clinical curriculum, misconceptions about EBHC, resistance of staff, lack of confidence of tutors, lack of time, and negative role modelling. Conclusions: Implementing clinically integrated EBHC curricula requires institutional support, a critical mass of the right teachers and role models in the clinical setting combined with patience, persistence and pragmatism on the part of teachers.
- ItemPerspectives of undergraduate module convenors at a South African academic institution on medical student training in evidence-based health care : a qualitative study(Taylor & Francis, 2015-09) Young, Taryn; Rohwer, Anke; Volmink, Jimmy; Clarke, MikeBackground: The increasing disease burden in Africa requires medical graduates to have problem-solving abilities. Interviews were conducted to assess module convenors’ perspectives on evidence-based health care (EBHC) teaching and learning. Methods: Qualitative research methods were used. Faculty convening medical undergraduate teaching modules were purposively sampled. Data collection was done using focus-group or individual interviews. Trained interviewers conducted interviews. Investigators conducted data analysis and interpretation. Results: Five focus groups and 10 individual interviews were conducted with convenors responsible for theory and clinical modules across various disciplines. Interviewees felt that EBHC teaching and learning were not optimal and indicated varying support for enhancing this. They identified various factors to be considered: contextual factors within the faculty (e.g. recognition for teaching), health sector issues (e.g. clinical workload), access to research, lecturer factors (e.g. competing priorities) and learners (e.g. motivation). They emphasised the key roles of lecturers as role models. Planning together to identify opportunities to integrate teaching and assessment, while ensuring coherence, clear explicit outcomes and promoting faculty development, was regarded as central to strengthening EBHC teaching and learning. Conclusions: The perspectives of module convenors are key to informing strategies to enhance EBHC teaching and learning.
- ItemPlagiarism in research : a survey of African medical journals(BMJ Publishing Group, 2018-11) Rohwer, Anke; Wager, Elizabeth; Young, Taryn; Garner, PaulObjectives To examine whether regional biomedical journals in Africa had policies on plagiarism and procedures to detect it; and to measure the extent of plagiarism in their original research articles and reviews. Design Cross sectional survey. Setting and participants We selected journals with an editor-in-chief in Africa, a publisher based in a low or middle income country and with author guidelines in English, and systematically searched the African Journals Online database. From each of the 100 journals identified, we randomly selected five original research articles or reviews published in 2016. Outcomes For included journals, we examined the presence of plagiarism policies and whether they referred to text matching software. We submitted articles to Turnitin and measured the extent of plagiarism (copying of someone else’s work) or redundancy (copying of one’s own work) against a set of criteria we had developed and piloted. Results Of the 100 journals, 26 had a policy on plagiarism and 16 referred to text matching software. Of 495 articles, 313 (63%; 95% CI 58 to 68) had evidence of plagiarism: 17% (83) had at least four linked copied or more than six individual copied sentences; 19% (96) had three to six copied sentences; and the remainder had one or two copied sentences. Plagiarism was more common in the introduction and discussion, and uncommon in the results. Conclusion Plagiarism is common in biomedical research articles and reviews published in Africa. While wholesale plagiarism was uncommon, moderate text plagiarism was extensive. This could rapidly be eliminated if journal editors implemented screening strategies, including text matching software.
- ItemSelf-management interventions for adolescents living with HIV : a systematic review(BMC (part of Springer Nature), 2021-05-07) Crowley, Talitha; Rohwer, AnkeBackground: Self-management interventions aim to enable people living with chronic conditions to increase control over their condition in order to achieve optimal health and may be pertinent for young people with chronic illnesses such as HIV. Our aim was to evaluate the effectiveness of self-management interventions for improving health-related outcomes of adolescents living with HIV (ALHIV) and identify the components that are most effective, particularly in low-resource settings with a high HIV burden. Methods: We considered randomised controlled trials (RCTs), cluster RCTs, non-randomised controlled trials (non- RCTs) and controlled before-after (CBA) studies. We did a comprehensive search up to 1 August 2019. Two authors independently screened titles, abstracts and full texts, extracted data and assessed the risk of bias. We synthesised results in a meta-analysis where studies were sufficiently homogenous. In case of substantial heterogeneity, we synthesised results narratively. We assessed the certainty of evidence using GRADE and presented our findings as summaries in tabulated form. Results: We included 14 studies, comprising 12 RCTs and two non-RCTs. Most studies were conducted in the United States, one in Thailand and four in Africa. Interventions were diverse, addressing a variety of selfmanagement domains and including a combination of individual, group, face-to-face, cell phone or information communication technology mediated approaches. Delivery agents varied from trained counsellors to healthcare workers and peers. Self-management interventions compared to usual care for ALHIV made little to no difference to most health-related outcomes, but the evidence is very uncertain. Self-management interventions may increase adherence and decrease HIV viral load, but the evidence is very uncertain. We could not identify any particular components of interventions that were more effective for improving certain outcomes. Conclusion: Existing evidence on the effectiveness of self-management interventions for improving health-related outcomes of ALHIV is very uncertain. Self-management interventions for ALHIV should take into account the individual, social and health system contexts. Intervention components need to be aligned to the desired outcomes.
- ItemWhat are the effects of teaching evidence-based health care (EBHC)? : overview of systematic reviews(PLoS, 2014-01) Young, Taryn; Rohwer, Anke; Volmink, Jimmy; Clarke, MikeBackground: An evidence-based approach to health care is recognized internationally as a key competency for healthcare practitioners. This overview systematically evaluated and organized evidence from systematic reviews on teaching evidence-based health care (EBHC). Methods/Findings: We searched for systematic reviews evaluating interventions for teaching EBHC to health professionals compared to no intervention or different strategies. Outcomes covered EBHC knowledge, skills, attitudes, practices and health outcomes. Comprehensive searches were conducted in April 2013. Two reviewers independently selected eligible reviews, extracted data and evaluated methodological quality. We included 16 systematic reviews, published between 1993 and 2013. There was considerable overlap across reviews. We found that 171 source studies included in the reviews related to 81 separate studies, of which 37 are in more than one review. Studies used various methodologies to evaluate educational interventions of varying content, format and duration in undergraduates, interns, residents and practicing health professionals. The evidence in the reviews showed that multifaceted, clinically integrated interventions, with assessment, led to improvements in knowledge, skills and attitudes. Interventions improved critical appraisal skills and integration of results into decisions, and improved knowledge, skills, attitudes and behaviour amongst practicing health professionals. Considering single interventions, EBHC knowledge and attitude were similar for lecture-based versus online teaching. Journal clubs appeared to increase clinical epidemiology and biostatistics knowledge and reading behavior, but not appraisal skills. EBHC courses improved appraisal skills and knowledge. Amongst practicing health professionals, interactive online courses with guided critical appraisal showed significant increase in knowledge and appraisal skills. A short workshop using problem-based approaches, compared to no intervention, increased knowledge but not appraisal skills. Conclusions: EBHC teaching and learning strategies should focus on implementing multifaceted, clinically integrated approaches with assessment. Future rigorous research should evaluate minimum components for multifaceted interventions, assessment of medium to long-term outcomes, and implementation of these interventions.
