RESUMO

OBJECTIVES: To identify candidate quality indicators from existing tools that provide guidance on how to practice knowledge translation and implemenation science (KT practice tools) across KT domains (dissemination, implementation, sustainability, and scalability). STUDY DESIGN AND SETTING: We conducted a scoping review using the Joanna Briggs Institute Manual for Evidence Synthesis. We systematically searched multiple electronic databases and the gray literature. Documents were independently screened, selected, and extracted by pairs of reviewers. Data about the included articles, KT practice tools, and candidate quality indicators were analyzed, categorized, and summarized descriptively. RESULTS: Of 43,060 titles and abstracts that were screened from electronic databases and gray literature, 850 potentially relevant full-text articles were identified, and 253 articles were included in the scoping review. Of these, we identified 232 unique KT practice tools from which 27 unique candidate quality indicators were generated. The identified candidate quality indicators were categorized according to the development (n = 17), evaluation (n = 5) and adaptation (n = 3) of the tools, and engagement of knowledge users (n = 2). No tools were identified that appraised the quality of KT practice tools. CONCLUSIONS: The development of a quality appraisal instrument of KT practice tools is needed. The results will be further refined and finalized in order to develop a quality appraisal instrument for KT practice tools.

RESUMO

OBJECTIVE: The objective of this scoping review is to identify and characterize relevant knowledge translation methods tools (those that provide guidance for optimized knowledge translation practice) to uncover candidate quality indicators to inform a future quality assessment tool for knowledge translation strategies. INTRODUCTION: Knowledge translation strategies (defined as including knowledge translation interventions, tools, and products) target various knowledge users, including patients, clinicians, researchers, and policy-makers. The development and use of strategies that support knowledge translation practice have been rapidly increasing, making it difficult for knowledge users to decide which to use. There is limited evidence-based guidance or measures to help assess the overall quality of knowledge translation strategies. INCLUSION CRITERIA: Empirical and non-empirical documents will be considered if they explicitly describe a knowledge translation methods tool and its development, evaluation or validation, methodological strengths or limitations, and/or use over time. The review will consider a knowledge translation methods tool if it falls within at least one knowledge translation domain (ie, implementation, dissemination, sustainability, scalability, integrated knowledge translation) in the health field. METHODS: We will conduct a systematic search of relevant electronic databases and gray literature. The search strategy will be developed iteratively by an experienced medical information specialist and peer-reviewed with the PRESS checklist. The search will be limited to English-only documents published from 2005 onward. Documents will be independently screened, selected, and extracted by 2 researchers. Data will be analyzed and summarized descriptively, including the characteristics of the included documents, knowledge translation methods tools, and candidate quality indicators.

RESUMO

BACKGROUND: Recent pandemics have provided important lessons to inform planning for public health emergencies. Despite these lessons, gaps in implementation during the COVID-19 pandemic are evident. Additionally, research to inform interventions to support the needs of front-line nurses during a prolonged pandemic are lacking. We aimed to gain an understanding of critical care nurses' perspectives of the ongoing pandemic, including their opinions of their organization and governments response to the pandemic, to inform interventions to improve the response to the current and future pandemics. METHODS: This sub-study is part of a cross-sectional online survey distributed to Canadian critical care nurses at two time points during the pandemic (March-May 2020; April-May 2021). We employed a qualitative descriptive design comprised of three open-ended questions to provide an opportunity for participants to share perspectives not specifically addressed in the main survey. Responses were analyzed using conventional content analysis. RESULTS: One hundred nine of the 168 (64.9%) participants in the second survey responded to the open-ended questions. While perspectives about effectiveness of both their organization's and the government's responses to the pandemic were mixed, most noted that inconsistent and unclear communication made it difficult to trust the information provided. Several participants who had worked during previous pandemics noted that their organization's COVID-19 response failed to incorporate lessons from these past experiences. Many respondents reported high levels of burnout and moral distress that negatively affected both their professional and personal lives. Despite these experiences, several respondents noted that support from co-workers had helped them to cope with the stress and challenges. CONCLUSION: One year into the pandemic, critical care nurses' lived experiences continue to reflect previously identified challenges and opportunities for improvement in pandemic preparedness and response. These findings suggest that lessons from the current and prior pandemics have been inadequately considered in the COVID-19 response. Incorporation of these perspectives into interventions to improve the health system response, and support the needs of critical care nurses is essential to fostering a resilient health workforce. Research to understand the experience of other front-line workers and to learn from more and less successful interventions, and leaders, is needed.

RESUMO

OBJECTIVE: The objective of this scoping review is to identify and map the evidence reporting the knowledge, skills, attitudes, beliefs, and implementation of evidence-based practice among nurses in low- and middle-income countries. INTRODUCTION: Evidence-based practice aims to improve health care quality, safety, and health system efficiency. Numerous research studies have explored nurses' engagement in evidence-based practice in high-income countries. Developing nations have recently joined the evidence-based practice movement, and primary research about nurses' engagement with it are emerging. INCLUSION CRITERIA: The scoping review will include primary studies (quantitative, qualitative, and mixed methods) and gray literature addressing knowledge, skills, attitudes, beliefs, and implementation of evidence-based practice among nurses. Participants will include registered nurses working in low- and middle-income countries. Studies conducted in all health care settings, including acute and community settings, in low- and middle-income countries will be included. METHODS: We will search MEDLINE, Embase, CINAHL, Scopus, ERIC, JBI Evidence-based Practice Database, Cochrane Library, LILACS, and AIM. Gray literature will be sourced from ProQuest Dissertations and Theses Global and Google Scholar for primary studies. Studies published in the English language will be included, with no limit on publication date. Titles, abstracts, and full-text articles will be assessed against the inclusion criteria by 2 independent reviewers. The extracted data will be analyzed quantitatively using frequencies and counts. Textual data from qualitative studies will be analyzed using descriptive content analysis. Results of the data analysis will be presented using graphs, tables, and a narrative format.

RESUMO

BACKGROUND: Despite improvement, sepsis mortality rates remain high, with an estimated 11 million sepsis-related deaths globally in 2017 (Rudd et. al, Lancet 395:200-211, 2020). Low- and middle-income countries (LMICs) are estimated to account for 85% of global sepsis mortality; however, evidence for improved sepsis mortality in LMICs is lacking. We aimed to improve sepsis care and outcomes through development and evaluation of a sepsis treatment protocol tailored to the Tikur Anbessa Specialized Hospital Emergency Department, Ethiopia, context. METHODS: We employed a mixed methods design, including an interrupted times series study, pre-post knowledge testing, and process evaluation. The primary outcome was the proportion of patients receiving appropriate sepsis care (blood culture collection before antibiotics and initiation of appropriate antibiotics within 1 h of assessment). Secondary outcomes included time to antibiotic administration, 72-h sepsis mortality, and 90-day all-cause mortality. Due to poor documentation, we were unable to assess our primary outcome and time to antibiotic administration. We used segmented regression with outcomes as binomial proportions to assess the impact of the intervention on mortality. Pre-post knowledge test scores were analyzed using the Student's t-test to compare group means for percentage of scenarios with correct diagnosis. RESULTS: A total of 113 and 300 patients were enrolled in the pre-implementation and post-implementation phases respectively. While age and gender were similar across the phases, a higher proportion (31 vs. 57%) of patients had malignancies in the post-implementation phase. We found a significant change in trend between the phases, with a trend for increasing odds of survival in the pre-implementation phase (OR 1.24, 95% CI 0.98-1.56), and a shift down, with odds of survival virtually flat (OR 0.95, 95% CI. 0.88-1.03) in the post-implementation phases for 72-h mortality, and trends for survival pre- and post-implementation are virtually flat for 90-day mortality. We found no significant difference in pre-post knowledge test scores, with interpretation limited by response rate. Implementation quality was negatively impacted by resource challenges. CONCLUSION: We found no improvement in sepsis outcomes, with a trend for increasing odds of survival lost post-implementation and no significant change in knowledge pre- and post-implementation. Variable availability of resources was the principal barrier to implementation. TRIAL REGISTRATION: Open Science Framework osf.io/ju4ga . Registered June 28, 2017.

RESUMO

OBJECTIVE: To assess implementation and to identify barriers and facilitators to implementation, sustainability and scalability of an implementation strategy to provide lay health workers (LHWs) with the knowledge, skills and tools needed to implement an intervention to support patient tuberculosis (TB) treatment adherence. DESIGN: Mixed-methods design including a cluster randomised controlled trial and process evaluation informed by the RE-AIM framework. SETTING: Forty-five health centres (HCs) in four districts in the south east zone of Malawi, who had an opportunity to receive cascade training. PARTICIPANTS: Forty-five peer-trainers (PTs), 23 patients and 20 LHWs. INTERVENTION: Implementation strategy employing peer-led educational outreach, a clinical support tool and peer support network to implement a TB treatment adherence intervention. OUTCOME MEASURES: Process data were collected from study initiation to the end-of-study PT meeting, and included: LHW and patient interviews, quarterly PT meeting notes, training logs and study team observations and meeting notes. Data sources were first analysed in isolation, followed by method, data source and analyst triangulation. Analyses were conducted independently by two study team members, and themes revised through discussion and involvement of additional study team members as needed. RESULTS: Forty-one HCs (91%) trained at least one LHW. Of 256 LHWs eligible to participate at study start 152 (59%) completed training, with the proportion trained per HC ranging from 0% to 100% at the end of initial cascade training. Lack of training incentives was the primary barrier to implementation, with intrinsic motivation to improve knowledge and skills, and to improve patient care and outcomes the primary facilitators of participation. CONCLUSION: We identified important challenges to and potential facilitators of implementation, scalability and sustainability, of the TB treatment adherence intervention. Findings provide guidance to scale-up, and use of the implementation strategies employed, to address LHW training and supervision in other areas. TRIAL REGISTRATION NUMBER: NCT02533089.

RESUMO

PURPOSE: Healthcare workers must ensure effective infection prevention and control (IPC) to prevent nosocomial spread of SARS-CoV-2, the virus that causes COVID-19. This questionnaire study aims to evaluate Canadian critical care and emergency department nurses' readiness to follow IPC guidelines in their workplace, and to understand their perceptions of trust in organizational preparedness, communication, and infection risk. METHODS: We adapted an internationally distributed survey for the Canadian context. This cross-sectional questionnaire, incorporating validated scales for items including institutional trust, was distributed by email to nurses via the Canadian Association of Critical Care Nurses and the Canadian Association of Emergency Physicians networks between 16 March and 25 May 2020. We evaluated intensive care unit and emergency department nurses' adherence to IPC protocols, barriers and facilitators to IPC guideline adherence, and their level of institutitonal trust. RESULTS: Three hundred and nineteen nurses responded to the survey. There was higher trust in organizational preparedness among nurses who were older (B = 0.31, P < 0.001) and more experienced (F = 18.09, P < 0.001), and particularly among those with previous experience working in outbreak settings (F = 7.87, P = 0.005). Compared with those without experience working in outbreak settings, respondents with this experience reported higher levels of fear of becoming ill and fear of providing care for COVID-19 patients (χ2 = 21.48, P = 0.002 and χ2 = 12.61, P = 0.05, respectively). Older and more experienced nurses reported greater comfort with IPC skills and easier access to personal protective equipment. While the vast majority (96%) of respondents reported using masks and gloves, only 83% had access to isolation facilities for suspected or confirmed COVID-19 cases. CONCLUSION: Canadian nurses had strong self-reported adherence to IPC measures and personal protective equipment use. There were high levels of trust in health system leadership to ensure protective measures are present and reliable. Trust was particularly high among older and more experienced nurses despite these populations reporting higher levels of fear of personal illness.


RéSUMé: OBJECTIF: Les travailleurs de la santé doivent assurer l'efficacité de la prévention et du contrôle des infections (PCI) pour prévenir la propagation nosocomiale du SRAS-CoV-2, le virus qui cause la COVID-19. Cette étude sous forme de questionnaire vise à évaluer le degré de préparation des infirmières et infirmiers des services d'urgence et de soins intensifs canadiens à suivre les lignes directrices de la PCI sur leur lieu de travail, ainsi qu'à comprendre leur degré de confiance dans la préparation, la communication et le risque d'infection au niveau de l'organisation. MéTHODE: Nous avons adapté un sondage distribué à l'échelle internationale au contexte canadien. Ce questionnaire sectoriel, incorporant des échelles validées pour des éléments tels que la confiance institutionnelle, a été distribué par courriel aux infirmières et infirmiers par l'entremise de l'Association canadienne des infirmiers/infirmières en soins intensifs et des réseaux de l'Association canadienne des médecins d'urgence entre le 16 mars et le 25 mai 2020. Nous avons évalué l'adhésion du personnel infirmier des unités de soins intensifs et des services d'urgence aux protocoles de la PCI, les obstacles et les facilitateurs à l'observance des lignes directrices de la PCI, ainsi que leur niveau de confiance institutionnelle. RéSULTATS: Trois cent dix-neuf infirmières et infirmiers ont répondu au questionnaire. Il y avait une plus grande confiance dans la préparation organisationnelle chez les infirmières et infirmiers plus âgés (B = 0,31, P < 0,001) et plus expérimentés (F = 18,09, P < 0,001), et en particulier parmi celles et ceux qui avaient déjà travaillé dans des contextes d'éclosion (F = 7,87, P = 0,005). Comparativement à celles et ceux qui n'ont pas d'expérience dans des contextes d'éclosion, les répondant(e)s avec expérience ont signalé des niveaux plus élevés de peur de tomber malade et de peur de fournir des soins aux patients atteints de la COVID-19 (χ2 = 21,48, P = 0,002 et χ2 = 12,61, P = 0,05, respectivement). Les infirmières et infirmiers plus âgés et plus expérimentés ont déclaré être plus à l'aise avec leurs compétences en PCI et avoir un meilleur accès aux équipements de protection individuelle. Alors que la grande majorité (96 %) des répondant(e)s ont déclaré avoir utilisé des masques et des gants, seulement 83 % avaient accès à des zones d'isolement pour les cas présumés ou confirmés de COVID-19. CONCLUSION: Les infirmières et infirmiers canadiens ont rapporté une forte adhésion aux mesures de la PCI et à l'utilisation des équipements de protection individuelle. Il y avait un niveau élevé de confiance dans le leadership du système de santé pour s'assurer que les mesures de protection étaient présentes et fiables. La confiance était particulièrement élevée chez le personnel infirmier plus âgé et plus expérimenté, bien les niveaux de peur d'être personnellement atteint de la maladie étaient plus élevés pour ces infirmières et infirmiers.

RESUMO

OBJECTIVES: The outcome of well-performed clinical research is essential for evidence-based patient management during pandemics. However, conducting clinical research amidst a pandemic requires researchers to balance clinical and research demands. We seek to understand the values, experiences, and beliefs of physicians working at the onset of the COVID-19 pandemic in order to inform clinical research planning. We aim to understand whether pandemic settings affect physician comfort with research practices, and how physician experiences shape their understanding of research in a pandemic setting. METHODS: A survey tool was adapted to evaluate familiarity and comfort with research during a pandemic. A cross-sectional, online questionnaire was distributed across Canadian research networks early in the COVID-19 outbreak. The survey was administered between March 11th and 17th, 2020, during a time of local transmission but prior to the surge of cases. We aimed to recruit into the survey physicians in infectious disease and critical care research networks across Canada. RESULTS: Of the 133 physician respondents, 131 (98%) considered it important to conduct clinical research during the COVID-19 pandemic. Respondents were more accepting of adaptations to the research process in during a pandemic compared to in a non-pandemic setting, including conducting research with deferred consent (χ2 = 8.941, 95% CI: -0.264, -0.085, p = 0.003), using non-identifiable observational data with a waiver of consent with a median score of 97 out of 100 (IQR: 79.25-100) vs median 87 out of 100 (IQR: 63-79) (95% CI: -12.43, 0.054, p = 0.052). The majority felt that research quality is not compromised during pandemics. CONCLUSIONS: Physicians consider it important to conduct research during a pandemic, highlighting the need to expedite research activities in pandemic settings. Respondents were more accepting of adaptations to the research process for research conducted during a pandemic, compared to that conducted in its absence of a pandemic.

RESUMO

BACKGROUND: With the global shortage of skilled health workers estimated at 7.2 million, outpatient tuberculosis (TB) care is commonly task-shifted to lay health workers (LHWs) in many low- and middle-income countries where the shortages are greatest. While shown to improve access to care and some health outcomes including TB treatment outcomes, lack of training and supervision limit the effectiveness of LHW programs. Our objective was to refine and evaluate an intervention designed to address common causes of non-adherence to TB treatment and LHW knowledge and skills training needs. METHODS: We employed a pragmatic cluster randomized controlled trial. Participants included 103 health centres (HCs) providing TB care in four districts in Malawi, randomized 1:1 stratified by district and HC funding (Ministry of Health, non-Ministry funded). At intervention HCs, a TB treatment adherence intervention was implemented using educational outreach, a point-of-care reminder tool, and a peer support network. Clusters in the control arm provided usual care. The primary outcome was the proportion of patients with successful TB treatment (i.e., cure or treatment completion). We used a generalized linear mixed model, with district as a fixed effect and HC as a random effect, to compare proportions of patients with treatment success, among the trial arms, with adjustment for baseline differences. RESULTS: We randomized 51 HCs to the intervention group and 52 HCs to the control group. Four intervention and six control HCs accrued no eligible patients, and 371 of 1169 patients had missing outcome, HC, or demographic data, which left 74 HCs and 798 patients for analysis. Randomization group was not related to missing outcome, however, district, age, and TB type were significantly related and included in the primary analysis model. Among the 1153 patients with HC and demographic data, 297/605 (49%) and 348/548 (64%) in the intervention and control arms, respectively, had treatment success. The intervention had no significant effect on treatment success (adjusted odds ratio 1.35 [95% confidence interval 0.93-1.98]). CONCLUSION: We found no significant effect of the intervention on TB treatment outcomes with high variability in implementation quality, highlighting important challenges to both scale-up and sustainability.

RESUMO

OBJECTIVES: We sought to map the evidence and identify interventions that increase initiation of antiretroviral therapy, adherence to antiretroviral therapy and retention in care for people living with HIV at high risk for poor engagement in care. METHODS: We conducted an overview of systematic reviews and sought for evidence on vulnerable populations (men who have sex with men (MSM), African, Caribbean and Black (ACB) people, sex workers (SWs), people who inject drugs (PWID) and indigenous people). We searched PubMed, Excerpta Medica dataBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science and the Cochrane Library in November 2018. We screened, extracted data and assessed methodological quality in duplicate and present a narrative synthesis. RESULTS: We identified 2420 records of which only 98 systematic reviews were eligible. Overall, 65/98 (66.3%) were at low risk of bias. Systematic reviews focused on ACB (66/98; 67.3%), MSM (32/98; 32.7%), PWID (6/98; 6.1%), SWs and prisoners (both 4/98; 4.1%). Interventions were: mixed (37/98; 37.8%), digital (22/98; 22.4%), behavioural or educational (9/98; 9.2%), peer or community based (8/98; 8.2%), health system (7/98; 7.1%), medication modification (6/98; 6.1%), economic (4/98; 4.1%), pharmacy based (3/98; 3.1%) or task-shifting (2/98; 2.0%). Most of the reviews concluded that the interventions effective (69/98; 70.4%), 17.3% (17/98) were neutral or were indeterminate 12.2% (12/98). Knowledge gaps were the types of participants included in primary studies (vulnerable populations not included), poor research quality of primary studies and poorly tailored interventions (not designed for vulnerable populations). Digital, mixed and peer/community-based interventions were reported to be effective across the continuum of care. CONCLUSIONS: Interventions along the care cascade are mostly focused on adherence and do not sufficiently address all vulnerable populations.

RESUMO

Therapies to reduce liver fibrosis and stimulate organ regeneration are urgently needed. We conducted a first-in-human, phase 1 dose-escalation trial of autologous macrophage therapy in nine adults with cirrhosis and a Model for End-Stage Liver Disease (MELD) score of 10-16 (ISRCTN 10368050). Groups of three participants received a single peripheral infusion of 107, 108 or up to 109 cells. Leukapheresis and macrophage infusion were well tolerated with no transfusion reactions, dose-limiting toxicities or macrophage activation syndrome. All participants were alive and transplant-free at one year, with only one clinical event recorded, the occurrence of minimal ascites. The primary outcomes of safety and feasibility were met. This study informs and provides a rationale for efficacy studies in cirrhosis and other fibrotic diseases.

RESUMO

OBJECTIVE: This review was conducted to identify interventions effective in improving uptake and retention of HIV-positive mothers and their infants in prevention of mother to child transmission (PMTCT) services in low-income and middle-income countries (LMICs) in order to inform programme planning. METHODS: We conducted a systematic review of studies comparing usual care with any intervention to improve uptake and retention of HIV-positive pregnant or breastfeeding women and their children from birth to 2 years of age in PMTCT services in LMICs. Twenty-two electronic databases were searched from inception to 15 January 2018, for randomised, quasi-randomised and non-randomised controlled trials, and interrupted time series studies; reference lists of included articles were searched for relevant articles. Risk of bias was assessed using the Cochrane Effective Practice and Organisation of Care group criteria. Random-effects meta-analysis was conducted for studies reporting similar interventions and outcomes. RESULTS: We identified 29 837 articles, of which 18 studies were included in our review. Because of heterogeneity in interventions and outcome measures, only one meta-analysis of two studies and one outcome was conducted; we found a statistically significant increase in antiretroviral therapy (ART) use during pregnancy for integration of HIV and antenatal care relative to standard non-integrated care (pooled AOR=2.69; 95% CI 1.25 to 5.78, p=0.0113). The remaining studies assessing other patient, provider or health system interventions were synthesised narratively, with small effects seen across intervention categories for both maternal and infant PMTCT outcomes based predominately on evidence with moderate to high risk of bias. CONCLUSIONS: Evidence on the effectiveness of interventions to improve uptake and retention of mothers and infants in PMTCT care is lacking. Our findings suggest that integration of HIV and antenatal care may improve ART use during pregnancy. Future studies to replicate promising approaches are needed. Improved reporting of key methodological criteria will facilitate interpretation of findings and improve the utility of evidence to PMTCT programme planners.

RESUMO

BACKGROUND: Evidence-based clinical algorithms (EBCA) are knowledge tools to promote evidence use by codifying evidence into action plans to facilitate appropriate care. However, their impact on process and outcomes of care varies considerably across practice settings and providers, highlighting the need for tailoring of both these knowledge tools and their implementation strategies to target end users and the setting in which EBCAs are to be employed. Leadership at the Tikur Anbessa Specialized Hospital emergency department (TASH-ED) in Addis Ababa, Ethiopia identified a need for context-appropriate EBCAs to improve evidence uptake to mitigate care gaps in this high volume, high acuity setting. We aimed to identify barriers and facilitators to utilization of EBCAs in the TASH-ED, to identify priority targets for development of EBCAs tailored for the TASH-ED context and to understand the process of care in the TASH-ED to inform implementation planning. METHODS: We employed a multi-component qualitative design including: semi-structured interviews with TASH-ED clinical, administrative and support services staff, and Toronto EM physicians who had worked in the TASH-ED; direct observation of the process of care in TASH-ED; document review. RESULTS: Although most TASH-ED participants reported an awareness of EBCAs, they noted little or no experience using them, primarily due to the poor fit of many EBCAs to their practice setting. All participants felt that context-appropriate EBCAs were needed to ensure standardized and evidence-based care and improve patient outcomes for common ED presentations. Trauma, sepsis, acute cardiac conditions, hypertensive emergencies, and diabetic keto-acidosis were most commonly identified as priorities for EBCA development. Lack of medication, equipment and human resources were identified as the primary barriers to use of EBCAs in the TASH-ED. Support from leadership and engagement of stakeholders outside the ED where EBCAs were believed to be less well accepted were identified as essential facilitators to implementation of EBCAs in the TASH-ED. CONCLUSIONS: This study found a perceived need for EBCAs tailored to the TASH-ED setting to support uptake of evidence-based care into routine practice for common clinical presentations. Barriers and facilitators provide information essential to development of both context-appropriate EBCAs and plans for their implementation in the TASH-ED.

RESUMO

This commentary provides an overview of the organizational readiness for change (ORC) literature over the last decade, with respect to prevailing definitions, theories, and tools to guide assessment of ORC in preparation for implementation. The development of the OR4KT by Gagnon et al is an important contribution to this body of work. This commentary highlights the strengths of the OR4KT including development based on two systematic reviews conducted by the authors to synthesize OR theory and measurement tools, and applicability to a wider range of high-income country healthcare settings through inclusion of input from a diverse group of international experts and transcultural adaptation of the tool, in the context of the literature to date. Limitations and future directions for further development of the tool are also discussed and include application of quantitative psychometric approaches and evaluation of the tool in a broader range of healthcare settings.

RESUMO

INTRODUCTION: While access to antiretroviral therapy (ART) for people living with HIV has expanded in recent years, additional efforts are required to support adherence to medication and retention in care. Interventions should be applicable in real-world settings and amenable to widespread use. The objectives of this overview are to identify effective pragmatic interventions that increase adherence to ART and retention in care for people living with HIV at high risk for suboptimal adherence and retention in high-income countries. METHODS AND ANALYSIS: We will conduct an overview of systematic reviews of studies on interventions which target improved adherence to medication and retention in care among high-risk people living with HIV in high-income countries (men who have sex with men, African, Caribbean and black people, sex workers, people who inject drugs, indigenous people and other socially marginalised groups). We will search the following databases: PubMed, EMBASE (Exerpta Medica Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycINFO, Web of Science and the Cochrane Library. We will conduct screening, data extraction and assessment of methodological quality of the systematic reviews. Analysis will be narrative. Our findings will be interpreted in light of the certainty of the evidence, level of pragmatism, setting and population of interest. ETHICS AND DISSEMINATION: Only published secondary data will be used in this study, and therefore ethics approval is not required. Our findings will be disseminated as peer-reviewed manuscripts, conference abstracts and through community activities. The findings from this overview will inform a mixed-methods study among people living with HIV and health workers in Ontario, Canada.

RESUMO

BACKGROUND: The Toronto-Addis Ababa Academic Collaboration in Emergency Medicine (TAAAC-EM) deploys teaching teams of Canadian EM faculty to Addis Ababa to deliver a longitudinal residency curriculum. Canadian trainees participate in these teams as a formally structured and supervised elective in global health (GH) and EM, which has been designed to enhance the strength of GH electives and address key challenges highlighted in the literature. METHODS: The purpose of this qualitative study was to identify, describe, and evaluate strengths and weaknesses of this elective in relation to its purposeful structure. Residents who completed the elective were invited to participate in face-to-face interviews to discuss their experiences. RESULTS: The findings show that the residents both chose this elective because of its purposefully designed features, and that these same features increased their enjoyment and the educational benefit of the elective. Supervised bedside teaching, relationships shared with Ethiopian residents, and the positive impact the experience had on their clinical practice in Canada were identified as the primary strengths. CONCLUSION: Purposeful and thoughtful design of global health electives can enhance the resident learning experience and mitigate challenges for trainees seeking global health training opportunities.

RESUMO

BACKGROUND: Health systems often fail to use evidence in clinical practice. In maternal and perinatal health, the majority of maternal, fetal and newborn mortality is preventable through implementing effective interventions. To meet this challenge, WHO's Department of Reproductive Health and Research partnered with the Knowledge Translation Program at St. Michael's Hospital (SMH), University of Toronto, Canada to establish a collaboration on knowledge translation (KT) in maternal and perinatal health, called the GREAT Network (Guideline-driven, Research priorities, Evidence synthesis, Application of evidence, and Transfer of knowledge). We applied a systematic approach incorporating evidence and theory to identifying barriers and facilitators to implementation of WHO maternal heath recommendations in four lower-income countries and to identifying implementation strategies to address these. METHODS: We conducted a mixed-methods study in Myanmar, Uganda, Tanzania and Ethiopia. In each country, stakeholder surveys, focus group discussions and prioritization exercises were used, involving multiple groups of health system stakeholders (including administrators, policymakers, NGOs, professional associations, frontline healthcare providers and researchers). RESULTS: Despite differences in guideline priorities and contexts, barriers identified across countries were often similar. Health system level factors, including health workforce shortages, and need for strengthened drug and equipment procurement, distribution and management systems, were consistently highlighted as limiting the capacity of providers to deliver high-quality care. Evidence-based health policies to support implementation, and improve the knowledge and skills of healthcare providers were also identified. Stakeholders identified a range of tailored strategies to address local barriers and leverage facilitators. CONCLUSION: This approach to identifying barriers, facilitators and potential strategies for improving implementation proved feasible in these four lower-income country settings. Further evaluation of the impact of implementing these strategies is needed.

RESUMO

BACKGROUND: Despite availability of effective treatment, tuberculosis (TB) remains an important cause of morbidity and mortality globally, with low- and middle-income countries most affected. In many such settings, including Malawi, the high burden of disease and severe shortage of skilled healthcare workers has led to task-shifting of outpatient TB care to lay health workers (LHWs). LHWs improve access to healthcare and some outcomes, including TB completion rates, but lack of training and supervision limit their impact. The goals of this study are to improve TB care provided by LHWs in Malawi by refining, implementing, and evaluating a knowledge translation strategy designed to address a recognized gap in LHWs' TB and job-specific knowledge and, through this, to improve patient outcomes. METHODS/DESIGN: We are employing a mixed-methods design that includes a pragmatic cluster randomized controlled trial and a process evaluation using qualitative methods. Trial participants will include all health centers providing TB care in four districts in the South East Zone of Malawi. The intervention employs educational outreach, a point-of-care reminder tool, and a peer support network. The primary outcome is proportion of treatment successes, defined as the total of TB patients cured or completing treatment, with outcomes taken from Ministry of Health treatment records. With an alpha of 0.05, power of 0.80, a baseline treatment success of 0.80, intraclass correlation coefficient of 0.1 based on our pilot study, and an estimated 100 clusters (health centers providing TB care), a minimum of 6 patients per cluster is required to detect a clinically significant 0.10 increase in the proportion of treatment successes. Our process evaluation will include interviews with LHWs and patients, and a document analysis of LHW training logs, quarterly peer trainer meetings, and mentorship meeting notes. An estimated 10-15 LHWs and 10-15 patients will be required to reach saturation in each of 2 planned interview periods, for a total of 40-60 interview participants. DISCUSSION: This study will directly inform the efforts of knowledge users within TB care and, through extension of the approach, other areas of care provided by LHWs in Malawi and other low- and middle-income countries.

RESUMO

OBJECTIVES: To explore similarities and differences in challenges to maternal health and evidence implementation in general across several low- and middle-income countries (LMICs) and to identify common and unique themes representing barriers to and facilitators of evidence implementation in LMIC health care settings. STUDY DESIGN: Secondary analysis of qualitative data. SETTING: Meeting reports and articles describing projects undertaken by the authors in five LMICs on three continents were analyzed. Projects focused on identifying barriers to and facilitators of implementation of evidence products: five World Health Organization maternal health guidelines, and a knowledge translation strategy to improve adherence to tuberculosis treatment. Data were analyzed using thematic content analysis. RESULTS: Among identified barriers to evidence implementation, a high degree of commonality was found across countries and clinical areas, with lack of financial, material, and human resources most prominent. In contrast, few facilitators were identified varied substantially across countries and evidence implementation products. CONCLUSION: By identifying common barriers and areas requiring additional attention to ensure capture of unique barriers and facilitators, these findings provide a starting point for development of a framework to guide the assessment of barriers to and facilitators of maternal health and potentially to evidence implementation more generally in LMICs.
