Integrating hypertension and HIV care in Namibia: A quality improvement collaborative approach

Prevalence of hypertension in community members in a low-income community in Windhoek, Namibia

BACKGROUND

 Hypertension remains a significant risk factor for the development of several non-communicable diseases such as stroke, myocardial infarction and renal failure. In many African countries, undiagnosed and unmanaged hypertension within the population remains a challenge. Proactive screening and health education therefore become important interventions.

AIM

 This study aimed to investigate the prevalence of hypertension among community members in a low-income, peri-urban community.

SETTING

 The study was conducted in Otjomuise township, Windhoek, Namibia.

METHODS

 A quantitative, cross-sectional design with a survey method was followed. A pre-validated health screening instrument was used to record the presence of hypertension in a sample of 358 community members who presented for screening over 2 days. A purposive sampling method was employed. Systolic and diastolic blood pressure reading were recorded, analysed and categorised using the American Heart Association classification scale. Blood pressures were classified as being either normal, elevated, hypertension stage 1 or hypertension stage 2. The data were analysed by a statistician using SPSS version 27 statistical software program and presented in tables.

RESULTS

 A total of 210/358 (59%) of participants were found to have blood pressures within normal limits. Moreover, 57/358 (16%) had elevated blood pressures, 52/358 (14%) were in hypertension stage 1 and 39/358 (11%) were in hypertension stage 2.

CONCLUSION

 The 41% prevalence of abnormally elevated blood pressures found in our study is in line with the findings of other studies and confirms that hypertension in the Namibian population remains an ongoing public health concern. Larger scale and more regular screening exercises with appropriate referral are recommended.Contribution: Our study give insight on the prevalence of hypertension in a community in Namibia.

Healthcare provider perspectives on barriers and facilitators to integration of cardiovascular disease-related care into HIV care and treatment clinics in urban Tanzania

Background

The increase in the dual burden of HIV and cardiovascular diseases (CVD), calls for the provision of integrated HIV/CVD care. This study aimed to explore barriers and facilitators to the integration of HIV/CVD care within HIV care and treatment clinics (CTCs) in urban, Tanzania.

Methods

Between March and April 2023, we conducted 12 key informant interviews with healthcare providers at six HIV CTCs in urban, Tanzania. Guided by the Consolidated Framework for Implementation Research (CFIR 1.0), we designed the interview guide and conducted a thematic analysis.

Results

Out of the 11 CFIR constructs explored, three were barriers (cost, availability of resources, and access to information and knowledge), six were facilitators (complexity, relative advantage, patient needs, external policies and incentives, relative priority, and knowledge and belief about the intervention), and two (compatibility and self-efficacy) were both barriers and facilitators. Barriers to integration included a lack of equipment, such as BP machines, lack of space, unavailability of an electronic data-capturing tool at the HIV CTCs for monitoring CVD outcomes, and a shortage of trained healthcare workers, particularly in managing CVD comorbidities according to current recommendations. Providers acknowledged the increasing demand for CVD care among ALHIV and regarded integration as not a complex task. Providers reported that both services could be delivered simultaneously without disrupting client workflow and were determined to offer integrated care within HIV CTCs. Providers expressed concerns about medication costs and recommended that medications should be provided for free as part of the integrated care.

Conclusion

Effective and sustainable HIV/CVD integrated care requires an understating of the existing barriers and facilitators within the HIV CTCs. This study identifies key barriers at HIV CTCs that must be addressed and facilitators to be leveraged before CVD care is integrated into HIV CTCs to ensure that CVD care is delivered effectively within an integrated system.

Lessons Learnt from HIV and Noncommunicable Disease Healthcare Integration in Sub-Saharan Africa

In sub-Saharan Africa (SSA), a rising burden of noncommunicable diseases (NCDs) coexists with a persistent high burden of human immunodeficiency virus (HIV). Integrating care for chronic conditions is potentially beneficial, but the optimal approach remains unclear. By use of a narrative review of 14 recent case studies from different SSA countries, examples of NCD and HIV healthcare integration were described. Case studies were categorized into three models: integrating NCD care into existing HIV care (n = 8), integrating HIV care into existing NCD care (n = 2), and simultaneous implementation of HIV and NCD services (n = 4). Facilitators include staff and patient education, while barriers encompass the lack of guidelines and inadequate infrastructure. Providers, patients, and policymakers support integrated care but note several challenges. Available health economics data suggest cost-effectiveness in the long run. Concluding, NCD and HIV healthcare integration in SSA was deemed feasible with models of service integration related to the implementation context.

Understanding barriers and facilitators to integrated HIV and hypertension care in South Africa

BACKGROUND

The burden of hypertension among people with HIV is high, particularly in low-and middle-income countries, yet gaps in hypertension screening and care in these settings persist. This study aimed to identify facilitators of and barriers to hypertension screening, treatment, and management among people with HIV in primary care clinics in Johannesburg, South Africa. Additionally, different stakeholder groups were included to identify discordant perceptions.

METHODS

Using a cross-sectional study design, data were collected via interviews (n = 53) with people with HIV and hypertension and clinic managers and focus group discussions (n = 9) with clinic staff. A qualitative framework analysis approach guided by COM-B and the Theoretical Domains Framework were used to identify and compare determinants of hypertension care across stakeholder groups.

RESULTS

Data from clinic staff and managers generated three themes characterizing facilitators of and barriers to the adoption and implementation of hypertension screening and treatment: 1) clinics have limited structural and operational capacity to support the implementation of integrated care models, 2) education and training on chronic care guidelines is inconsistent and often lacking across clinics, and 3) clinicians have the goal of enhancing chronic care within their clinics but first need to advocate for health system characteristics that will sustainably support integrated care. Patient data generated three themes characterizing existing facilitators of and barriers to clinic attendance and chronic disease self-management: 1) the threat of hypertension-related morbidity and mortality as a motivator for lifestyle change, 2) the emotional toll of clinic's logistical, staff, and resource challenges, and 3) hypertension self-management as a patchwork of informational and support sources. The main barriers to hypertension screening, treatment, and management were related to environmental resources and context (i.e., lack of enabling resources and siloed flow of clinic operations) and patients' knowledge and emotions (i.e., lack of awareness about hypertension risk, fear, and frustration). Clinical actors and patients differed in perceived need to prioritize HIV versus hypertension care.

CONCLUSIONS

The convergence of multi-stakeholder data highlight key areas for improvement, where tailored implementation strategies targeting motivations of clinic staff and capacity of patients may address challenges to hypertension screening, treatment, and management recognized across groups.

Mapping evidence on barriers to and facilitators of diagnosing noncommunicable diseases among people living with human immunodeficiency virus in low- and middle-income countries in Africa: A scoping review

Objectives

To map the evidence on the barriers to and facilitators of diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries in Africa.

Introduction

Noncommunicable diseases are increasing among people living with HIV. Thus, strengthened and sustained diagnosis of noncommunicable diseases through integrated noncommunicable diseases and HIV care is needed to improve patient outcomes. However, there is paucity of evidence on the barriers and facilitators diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries.

Methods

The Arksey and O'Malley methodological framework was used. A comprehensive systematic search of academic databases (MEDLINE, Academic Search Complete, APA PsycInfo, CAB, and Health Source/Nursing) was performed via EBSCO search and PubMed. The articles were reviewed independently by three reviewers. The results were structured using Capability-Opportunity-Motivation-Behavior model and Theoretical Domains Framework.

Results

A total of 152 articles were retrieved for full-text review. Forty-one articles met the inclusion criteria. The identified barriers were relevant to all the Capability-Opportunity-Motivation-Behavior constructs and 14 Theoretical Domains Framework domains. A lack of knowledge and awareness of noncommunicable diseases, fear of stigma, financial problems and out-of-pocket payments were the most cited patient-level barriers. Healthcare providers (knowledge and awareness gaps, skill and competence deficiencies, unwillingness, burnout, low motivation, and apathy) were frequently cited. Lack of equipment, noncommunicable disease medications and supply chain challenges, lack of integrated noncommunicable disease and HIV care, and shortage of trained healthcare providers were identified as health-system-level barriers.

Conclusion

This scoping review is the first to identify barriers and facilitators using a theoretical framework. The most cited barriers include a lack of integrated HIV and noncommunicable disease care, equipment and logistics chain challenges for noncommunicable diseases, patients' and healthcare providers' lack of knowledge and awareness of noncommunicable diseases, and healthcare provider's skill and competency deficiencies. Addressing these issues is crucial for improving patient outcomes and reducing the burden on healthcare providers and health systems.

Understanding Barriers and Facilitators to Integrated HIV and Hypertension Care in South Africa

Background The burden of hypertension among people with HIV is high, particularly in low-and middle-income countries, yet gaps in hypertension screening and care in these settings persist. The objective of this study was to identify facilitators of and barriers to hypertension screening, treatment, and management among people with HIV seeking treatment in primary care clinics in Johannesburg, South Africa.

Barriers to and enablers of quality improvement in primary health care in low- and middle-income countries: A systematic review

The quality of health care remains generally poor across primary health care settings, especially in low- and middle-income countries where tertiary care tends to take up much of the limited resources despite primary health care being the first (and often the only) point of contact with the health system for nearly 80 per cent of people in these countries. Evidence is needed on barriers and enablers of quality improvement initiatives. This systematic review sought to answer the question: What are the enablers of and barriers to quality improvement in primary health care in low- and middle-income countries? It adopted an integrative review approach with narrative evidence synthesis, which combined qualitative and mixed methods research studies systematically. Using a customized geographic search filter for LMICs developed by the Cochrane Collaboration, Scopus, Academic Search Ultimate, MEDLINE, CINAHL, PSYCHINFO, EMBASE, ProQuest Dissertations and Overton.io (a new database for LMIC literature) were searched in January and February 2023, as were selected websites and journals. 7,077 reports were retrieved. After removing duplicates, reviewers independently screened titles, abstracts and full texts, performed quality appraisal and data extraction, followed by analysis and synthesis. 50 reports from 47 studies were included, covering 52 LMIC settings. Six themes related to barriers and enablers of quality improvement were identified and organized using the model for understanding success in quality (MUSIQ) and the consolidated framework for implementation research (CFIR). These were: microsystem of quality improvement, intervention attributes, implementing organization and team, health systems support and capacity, external environment and structural factors, and execution. Decision makers, practitioners, funders, implementers, and other stakeholders can use the evidence from this systematic review to minimize barriers and amplify enablers to better the chances that quality improvement initiatives will be successful in resource-limited settings.

Care Cascades for Hypertension in Low-Income Settings: A Systematic Review and Meta-Analysis

Objective: High blood pressure is the leading risk factor for cardiovascular disease. The hypertension care cascade (HCC) is increasingly being used to evaluate the effectiveness of interventions. This systematic review aims to examine HCC in low-income settings. Methods: The search strategy included articles published between January 2010 and April 2023. We excluded studies with incomplete HCC, on fragile patients or aged <18 years, reviews. We used the MOOSE guideline. Five researchers retrieved data on the survey year, country, population, HCC and diagnostic methods for hypertension. We used JBI Critical Appraisal Tools for quality assessment. Results: Ninety-five articles were analyzed. Average hypertension prevalence was 33% (95% CI: 31%-34%), lower in LICs than in LMICs (25% vs. 34%). The overall mean awareness of hypertension was 48% (95% CI: 45%-51%), its treatment was 35% (95% IC: 32%-38%) and its control 16% (95% CI: 14%-18%). In almost all steps, percentages were lower in LICs and in Sub-Saharan Africa. Conclusion: Trends in HCC vary between countries, with poorer performance in LICs. This review highlights the need for interventions tailored to low-income settings in order to improve hypertension care.
