Models of integration of HIV and noncommunicable disease care in sub-Saharan Africa: lessons learned and evidence gaps

Forecasting the effect of HIV-targeted interventions on the age distribution of people with HIV in Kenya

OBJECTIVES

To provide accurate forecasts of the age distribution of people with HIV (PWH) in Kenya from 2025 to 2040.

DESIGN

Development of a compartmental model of HIV in Kenya, calibrated to historical estimates of HIV epidemiology.

METHODS

We forecasted changes in population size and age distribution of new HIV infections and PWH under the status quo and under scale-up of HIV services.

RESULTS

Without scale-up, new HIV infections were forecasted to fall from 34 000 (28 000-41 000) in 2,025 to 29 000 (15 000-57 000) in 2,040; the percentage of new infections occurring among persons over 30 increased from 33% (20-50%) to 40% (24-62%). The median age of PWH increased from 39 years (38-40) in 2025 to 43 years (39-46) in 2040, and the percentage of PWH over age 50 increased from 26% (23-29%) to 34% (26-43%). Under the full intervention scenario, new infections were forecasted to fall to 6,000 (3,000-12 000) in 2,040. The percentage of new infections occurring in people over age 30 increased to 52% (34-71%) in 2,040, and there was an additional shift in the age structure of PWH [forecasted median age of 46 (43-48) and 40% (33-47%) over age 50].

CONCLUSION

PWH in Kenya are forecasted to age over the next 15 years; improvements to the HIV care continuum are expected to contribute to the growing proportion of older PWH.

Sickle cell trait, APOL1 risk allele status and chronic kidney disease among ART-experienced adults living with HIV in northern Nigeria

BACKGROUND

We sought to determine the prevalence of sickle cell trait (SCT) and apolipoprotein-1 (APOL1) risk variants in people living with HIV (PLWH) in Nigeria, and to establish if SCT and APOL1 high-risk status correlate with estimated glomerular filtration rate (eGFR) and/or prevalent chronic kidney disease (CKD).

METHODS

Baseline demographic and clinical data were obtained during three cross-sectional visits. CKD was defined as having an eGFR<60 mL/min/1.73 m2. We collected urine specimens to determine urine albumin-creatine ratio and blood samples for sickle cell genotyping, APOL1 testing, and for creatinine/cystatin C assessment. The associations between SCT, APOL1 genotype, and eGFR/CKD stages/CKD were investigated using linear/ordinal logistic/logistic regression models, respectively.

RESULTS

Of 2443 participants, 599 (24.5%) had SCT, and 2291 (93.8%) had a low-risk APOL1 genotype (0 or 1 risk variant), while 152 (6.2%) had high-risk genotype (2 allele copies). In total, 108 participants (4.4%) were diagnosed with CKD. In adjusted analyses, SCT was associated with lower eGFR (adjusted mean difference [aMD]= -2.33, 95% CI -4.25, -0.42), but not with worse CKD stages, or increased odds of developing CKD. Participants with the APOL1 high risk genotype were more likely to have lower eGFR (aMD= -5.45, 95% CI -8.87, -2.03), to develop CKD (adjusted odds ratio [aOR] = 1.97, 95% CI: 1.03, 3.75), and to be in worse CKD stages (aOR = 1.60, 95% CI: 1.12, 2.29) than those with the low-risk genotype. There was no evidence of interaction between SCT and APOL1 genotype on eGFR or risk of CKD.

CONCLUSION

Our findings highlight the multifaceted interplay of genetic factors in the pathogenesis of CKD in PLWH.

A mixed methods approach identifying facilitators and barriers to guide adaptations to InterCARE strategies: an integrated HIV and hypertension care model in Botswana

BACKGROUND

Botswana serves as a model of success for HIV with 95% of people living with HIV (PLWH) virally suppressed. Yet, only 19% of PLWH and hypertension have controlled blood pressure. To address this gap, InterCARE, a care model that integrates HIV and hypertension care through a) provider training; b) adapted electronic health record; and c) treatment partners (peer support), was designed. This study presents results from our baseline assessment of the determinants and factors used to guide adaptations to InterCARE implementation strategies prior to a hybrid type 2 effectiveness-implementation study.

METHODS

This study employed a convergent mixed methods design across two clinics (one rural, one urban) to collect quantitative and qualitative data through facility assessments, 100 stakeholder surveys (20 each PLWH and hypertension, existing HIV treatment partners, clinical healthcare providers (HCPs), and 40 community leaders) and ten stakeholder key informative interviews (KIIs). Data were analyzed using descriptive statistics and deductive qualitative analysis organized by the Consolidated Framework for Implementation Research (CFIR) and compared to identify areas of convergence and divergence.

RESULTS

Although 90.3% of 290 PLWH and hypertension at the clinics were taking antihypertensive medications, 52.8% had uncontrolled blood pressure. Results from facility assessments, surveys, and KIIs identified key determinants in the CFIR innovation and inner setting domains. Most stakeholders (> 85%) agreed that InterCARE was adaptable, compatible and would be successful at improving blood pressure control in PLWH and hypertension. HCPs agreed that there were insufficient resources (40%), consistent with facility assessments and KIIs which identified limited staffing, inconsistent electricity, and a lack of supplies as key barriers. Adaptations to InterCARE included a task-sharing strategy and expanded treatment partner training and support.

CONCLUSIONS

Integrating hypertension services into HIV clinics was perceived as more advantageous for PLWH than the current model of hypertension care delivered outside of HIV clinics. Identified barriers were used to adapt InterCARE implementation strategies for more effective intervention delivery.

Mapping the evidence on integrated service delivery for non-communicable and infectious disease comorbidity in sub-Saharan Africa: protocol for a scoping review

INTRODUCTION

The concurrent occurrence of infectious diseases (IDs) and non-communicable diseases (NCDs) presents complex healthcare challenges in sub-Saharan Africa (SSA), where healthcare systems often grapple with limited resources. While an integrated care approach has been advocated to address these complex challenges, there is a recognised gap in comprehensive evidence regarding the various models of integrated care, their components and the feasibility of their implementation. This scoping review aims to bridge this gap by examining the breadth and nature of evidence on integrated care models for NCDs and IDs within SSA, thereby updating the current evidence base in the domain.

METHODS AND ANALYSIS

Based on the Joanna Briggs Institute (JBI) framework for scoping reviews, this study will include peer-reviewed and grey literature reporting on integrated care models for NCD-ID comorbidities in SSA. A comprehensive search of published sources in electronic databases (PubMed, Scopus, Embase, the Cochrane Library, Health System Evidence and Research4Life) and grey literature (Google Scholar, EBSCO Open Dissertations and relevant organisational websites) will be conducted to identify sources of information reported in English from 2018 onwards. The review will consider sources of evidence reporting on integrated care model for NCDs such as diabetes; chronic cardiovascular, respiratory and kidney diseases; cancers; epilepsy; and mental illness, and comorbid IDs such as HIV, tuberculosis and malaria. All sources of evidence will be considered irrespective of the study designs or methods used. The review will exclude sources that solely focus on the differentiated or patient-centred care delivery approach, and that focus on other conditions, populations or settings. The reviewers will independently screen the sources for eligibility and extract data using a JBI-adapted data tool on the Parsifal review platform. Data will be analysed using descriptive and thematic analyses and results will be presented in tables, figures, diagrams and a narrative summary.

ETHICS AND DISSEMINATION

Ethical approval is not required for this review as it will synthesise published data and does not involve human participants. The final report will be submitted for publication in a peer-reviewed journal. The findings will be used to inform future research.

Evaluating a multifaceted implementation strategy and package of evidence-based interventions based on WHO PEN for people living with HIV and cardiometabolic conditions in Lusaka, Zambia: protocol for the TASKPEN hybrid effectiveness-implementation stepped wedge cluster randomized trial

BACKGROUND

Despite increasing morbidity and mortality from non-communicable diseases (NCD) globally, health systems in low- and middle-income countries (LMICs) have limited capacity to address these chronic conditions, particularly in sub-Saharan Africa (SSA). There is an urgent need, therefore, to respond to NCDs in SSA, beginning by applying lessons learned from the first global response to any chronic disease-HIV-to tackle the leading cardiometabolic killers of people living with HIV (PLHIV). We have developed a feasible and acceptable package of evidence-based interventions and a multi-faceted implementation strategy, known as "TASKPEN," that has been adapted to the Zambian setting to address hypertension, diabetes, and dyslipidemia. The TASKPEN multifaceted implementation strategy focuses on reorganizing service delivery for integrated HIV-NCD care and features task-shifting, practice facilitation, and leveraging HIV platforms for NCD care. We propose a hybrid type II effectiveness-implementation stepped-wedge cluster randomized trial to evaluate the effects of TASKPEN on clinical and implementation outcomes, including dual control of HIV and cardiometabolic NCDs, as well as quality of life, intervention reach, and cost-effectiveness.

METHODS

The trial will be conducted in 12 urban health facilities in Lusaka, Zambia over a 30-month period. Clinical outcomes will be assessed via surveys with PLHIV accessing routine HIV services, and a prospective cohort of PLHIV with cardiometabolic comorbidities nested within the larger trial. We will also collect data using mixed methods, including in-depth interviews, questionnaires, focus group discussions, and structured observations, and estimate cost-effectiveness through time-and-motion studies and other costing methods, to understand implementation outcomes according to Proctor's Outcomes for Implementation Research, the Consolidated Framework for Implementation Research, and selected dimensions of RE-AIM.

DISCUSSION

Findings from this study will be used to make discrete, actionable, and context-specific recommendations in Zambia and the region for integrating cardiometabolic NCD care into national HIV treatment programs. While the TASKPEN study focuses on cardiometabolic NCDs in PLHIV, the multifaceted implementation strategy studied will be relevant to other NCDs and to people without HIV. It is expected that the trial will generate new insights that enable delivery of high-quality integrated HIV-NCD care, which may improve cardiovascular morbidity and viral suppression for PLHIV in SSA. This study was registered at ClinicalTrials.gov (NCT05950919).

Tobacco smoking, smoking cessation and life expectancy among people with HIV on antiretroviral therapy in South Africa: a simulation modelling study

INTRODUCTION

As access to effective antiretroviral therapy (ART) has improved globally, tobacco-related illnesses, including cardiovascular disease, cancer and chronic respiratory conditions, account for a growing proportion of deaths among people with HIV (PWH). We estimated the impact of tobacco smoking and smoking cessation on life expectancy among PWH in South Africa.

METHODS

In a microsimulation model, we simulated 18 cohorts of PWH with virologic suppression, each homogenous by sex, initial age (35y/45y/55y) and smoking status (current/former/never). Input parameters were from data sources published between 2008 and 2022. We used South African data to estimate age-stratified mortality hazard ratios: 1.2-2.3 (females)/1.1-1.9 (males) for people with current versus never smoking status; and 1.0-1.3 (females)/1.0-1.5 (males) for people with former versus never smoking status, depending on age at cessation. We assumed smoking status remains unchanged during the simulation; people who formerly smoked quit at model start. Simulated PWH face a monthly probability of disengagement from care and virologic non-suppression. In sensitivity analysis, we varied smoking-associated and HIV-associated mortality risks. Additionally, we estimated the total life-years gained if a proportion of all virologically suppressed PWH stopped smoking.

RESULTS

Forty-five-year-old females/males with HIV with virologic suppression who smoke lose 5.3/3.7 life-years compared to PWH who never smoke. Smoking cessation at age 45y adds 3.4/2.4 life-years. Simulated PWH who continue smoking lose more life-years from smoking than from HIV (females, 5.3 vs. 3.0 life-years; males, 3.7 vs. 2.6 life-years). The impact of smoking and smoking cessation increase as smoking-associated mortality risks increase and HIV-associated mortality risks, including disengagement from care, decrease. Model results are most sensitive to the smoking-associated mortality hazard ratio; varying this parameter results in 1.0-5.1 life-years gained from cessation at age 45y. If 10-25% of virologically suppressed PWH aged 30-59y in South Africa stopped smoking now, 190,000-460,000 life-years would be gained.

CONCLUSIONS

Among virologically suppressed PWH in South Africa, tobacco smoking decreases life expectancy more than HIV. Integrating tobacco cessation interventions into HIV care, as endorsed by the World Health Organization, could substantially improve life expectancy.

Tackling syndemics by integrating infectious and noncommunicable diseases in health systems of low- and middle-income countries: A narrative systematic review

The co-occurrence of infectious diseases (ID) and non-communicable diseases (NCD) is widespread, presenting health service delivery challenges especially in low-and middle-income countries (LMICs). Integrated health care is a possible solution but may require a paradigm shift to be successfully implemented. This literature review identifies integrated care examples among selected ID and NCD dyads. We searched PubMed, PsycINFO, Cochrane Library, CINAHL, Web of Science, EMBASE, Global Health Database, and selected clinical trials registries. Eligible studies were published between 2010 and December 2022, available in English, and report health service delivery programs or policies for the selected disease dyads in LMICs. We identified 111 studies that met the inclusion criteria, including 56 on tuberculosis and diabetes integration, 46 on health system adaptations to treat COVID-19 and cardiometabolic diseases, and 9 on COVID-19, diabetes, and tuberculosis screening. Prior to the COVID-19 pandemic, most studies on diabetes-tuberculosis integration focused on clinical service delivery screening. By far the most reported health system outcomes across all studies related to health service delivery (n = 72), and 19 addressed health workforce. Outcomes related to health information systems (n = 5), leadership and governance (n = 3), health financing (n = 2), and essential medicines (n = 4)) were sparse. Telemedicine service delivery was the most common adaptation described in studies on COVID-19 and either cardiometabolic diseases or diabetes and tuberculosis. ID-NCD integration is being explored by health systems to deal with increasingly complex health needs, including comorbidities. High excess mortality from COVID-19 associated with NCD-related comorbidity prompted calls for more integrated ID-NCD surveillance and solutions. Evidence of clinical integration of health service delivery and workforce has grown-especially for HIV and NCDs-but other health system building blocks, particularly access to essential medicines, health financing, and leadership and governance, remain in disease silos.

Barriers to accessing care for cardiometabolic disorders in Malawi: partners as a source of resilience for people living with HIV

BACKGROUND

People living with HIV (PLWH) are at increased risk of cardiometabolic disorders (CMD). Adequate access to care for both HIV and CMD is crucial to improving health outcomes; however, there is limited research that have examined couples' experiences accessing such care in resource-constrained settings. We aimed to identify barriers to accessing CMD care among PLWH in Malawi and the role of partners in mitigating these barriers.

METHODS

We conducted a qualitative investigation of barriers to CMD care among 25 couples in Malawi. Couples were eligible if at least one partner was living with HIV and had hypertension or diabetes (i.e., the index patient). Index patients were recruited from HIV care clinics in the Zomba district, and their partners were enrolled thereafter. Interviews were conducted separately with both partners to determine barriers to CMD care access and how partners were involved in care.

RESULTS

Participants framed their experiences with CMD care by making comparisons to HIV treatment, which was free and consistently available. The main barriers to accessing CMD care included shortage of medications, cost of tests and treatments, high cost of transportation to health facilities, lengthy wait times at health facilities, faulty or unavailable medical equipment and supplies, inadequate monitoring of patients' health conditions, some cultural beliefs about causes of illness, use of herbal therapies as an alternative to prescribed medicine, and inadequate knowledge about CMD treatments. Partners provided support through decision-making on accessing medical care, assisting partners in navigating the healthcare system, and providing financial assistance with transportation and treatment expenses. Partners also helped manage care for CMD, including communicating health information to their partners, providing appointment reminders, supporting medication adherence, and supporting recommended lifestyle behaviors.

CONCLUSIONS

Couples identified many barriers to CMD care access, which were perceived as greater challenges than HIV care. Partners provided critical forms of support in navigating these barriers. With the rise of CMD among PLWH, improving access to CMD care should be prioritized, using lessons learned from HIV and integrated care approaches. Partner involvement in CMD care may help mitigate most barriers to CMD care.

The Evidence Project: Protocol for Systematic Reviews of Behavioral Interventions and Behavioral Aspects of Biomedical Interventions for HIV Prevention, Treatment, and Health Service Delivery in Low- and Middle-Income Countries

The Evidence Project conducts systematic reviews and meta-analyses of HIV behavioral interventions, behavioral aspects of biomedical interventions, combination prevention strategies, modes of service delivery, and integrated programs in low- and middle-income countries. Here, we present the overall protocol for our reviews. For each topic, we conduct a comprehensive search of five online databases, complemented by secondary reference searching. Articles are included if they are published in peer-reviewed journals and present pre/post or multi-arm data on outcomes of interest. Data are extracted from each included article by two trained coders working independently using standardized coding forms, with differences resolved by consensus. Risk of bias is assessed with the Evidence Project tool. Data are synthesized descriptively, and meta-analysis is conducted when there are similarly measured outcomes across studies. For over 20 years, this approach has allowed us to synthesize literature on the effectiveness of interventions and contribute to the global HIV response.

Implementing and evaluating integrated care models for non-communicable diseases in fragile and humanitarian settings

In this commentary, we advocate for the wider implementation of integrated care models for NCDs within humanitarian preparedness, response, and resilience efforts. Since experience and evidence on integrated NCD care in humanitarian settings is limited, we discuss potential benefits, key lessons learned from other settings, and lessons from the integration of other conditions that may be useful for stakeholders considering an integrated model of NCD care. We also introduce our ongoing project in North Lebanon as a case example currently undergoing parallel tracks of program implementation and process evaluation that aims to strengthen the evidence base on implementing an integrated NCD care model in a crisis setting.

"I only seek treatment when I am ill": experiences of hypertension and diabetes care among adults living with HIV in urban Tanzania

BACKGROUND

For adults living with HIV (ALHIV) and comorbidities, access to comprehensive healthcare services is crucial to achieving optimal health outcomes. This study aims to describe lived experiences, challenges, and coping strategies for accessing care for hypertension and/or diabetes (HTN/DM) in HIV care and treatment clinics (CTCs) and other healthcare settings.

METHODOLOGY

We conducted a qualitative study that employed a phenomenological approach between January and April 2022 using a semi-structured interview guide in six HIV CTCs in Dar es Salaam, Tanzania. We purposively recruited 33 ALHIV with HTN (n = 16), DM (n = 10), and both (n = 7). Thematic content analysis was guided by the 5As framework of access to care.

FINDINGS

The majority of the participants were females, between the ages of 54-73, and were recruited from regional referral hospitals. HIV CTCs at regional referral hospitals had more consistent provision of HTN screening services compared to those from district hospitals and health centers. Participants sought HTN/DM care at non-CTC health facilities due to the limited availability of such services at HIV CTCs. However, healthcare delivery for these conditions was perceived as unaccommodating and poorly coordinated. The need to attend multiple clinic appointments for the management of HTN/DM in addition to HIV care was perceived as frustrating, time-consuming, and financially burdensome. High costs of care and transportation, limited understanding of comorbidities, and the perceived complexity of HTN/DM care contributed to HTN/DM treatment discontinuity. As a means of coping, participants frequently monitored their own HTN/DM symptoms at home and utilized community pharmacies and dispensaries near their residences to check blood pressure and sugar levels and obtain medications. Participants expressed a preference for non-pharmaceutical approaches to comorbidity management such as lifestyle modification (preferred by young participants) and herbal therapies (preferred by older participants) because of concerns about side effects and perceived ineffectiveness of HTN/DM medications. Participants also preferred integrated care and focused patient education on multimorbidity management at HIV CTCs.

CONCLUSION

Our findings highlight significant barriers to accessing HTN/DM care among ALHIV, mostly related to affordability, availability, and accessibility. Integration of NCD care into HIV CTCs, could greatly improve ALHIV health access and outcomes and align with patient preference.

Assets for integrating task-sharing strategies for hypertension within HIV clinics: Stakeholder's perspectives using the PEN-3 cultural model

BACKGROUND

Access to antiretroviral therapy has increased life expectancy and survival among people living with HIV (PLWH) in African countries like Nigeria. Unfortunately, non-communicable diseases such as cardiovascular diseases are on the rise as important drivers of morbidity and mortality rates among this group. The aim of this study was to explore the perspectives of key stakeholders in Nigeria on the integration of evidence-based task-sharing strategies for hypertension care (TASSH) within existing HIV clinics in Nigeria.

METHODS

Stakeholders representing PLWH, patient advocates, health care professionals (i.e. community health nurses, physicians and chief medical officers), as well as policymakers, completed in-depth qualitative interviews. Stakeholders were asked to discuss facilitators and barriers likely to influence the integration of TASSH within HIV clinics in Akwa Ibom, Nigeria. The interviews were transcribed, keywords and phrases were coded using the PEN-3 cultural model as a guide. Framework thematic analysis guided by the PEN-3 cultural model was used to identify emergent themes.

RESULTS

Twenty-four stakeholders participated in the interviews. Analysis of the transcribed data using the PEN-3 cultural model as a guide yielded three emergent themes as assets for the integration of TASSH in existing HIV clinics. The themes identified are: 1) extending continuity of care among PLWH; 2) empowering health care professionals and 3) enhancing existing workflow, staff motivation, and stakeholder advocacy to strengthen the capacity of HIV clinics to integrate TASSH.

CONCLUSION

These findings advance the field by providing key stakeholders with knowledge of assets within HIV clinics that can be harnessed to enhance the integration of TASSH for PLWH in Nigeria. Future studies should evaluate the effect of these assets on the implementation of TASSH within HIV clinics as well as their effect on patient-level outcomes over time.

Six month incidence of major adverse cardiovascular events among adults with HIV in northern Tanzania: a prospective observational study

OBJECTIVES

We aimed to prospectively describe incident cardiovascular events among people living with HIV (PLWH) in northern Tanzania. Secondary aims of this study were to understand non-communicable disease care-seeking behaviour and patient preferences for cardiovascular care and education.

DESIGN

A prospective observational study.

SETTING

This study was conducted at the Majengo HIV Care and Treatment Clinic, an outpatient government-funded clinic in Moshi, Tanzania PARTICIPANTS: Adult patients presenting to an HIV clinic for routine care in northern Tanzania were enrolled from 1 September 2020 to 1 March 2021.

INTERVENTIONS

At enrolment, participants completed a survey and a resting 12-lead ECG was obtained. At 6 month follow-up, a repeat survey regarding interim health events and repeat ECG was obtained.

PRIMARY AND SECONDARY OUTCOME MEASURES

Interim major adverse cardiovascular events (MACE) were defined by: self-reported interim stroke, self-reported hospitalisation for heart failure, self-reported interim myocardial infarction, interim myocardial infarction by ECG criteria (new pathologic Q waves in two contiguous leads) or death due to cardiovascular disease (CVD).

RESULTS

Of 500 enrolled participants, 477 (95.4%) completed 6 month follow-up and 3 (0.6%) died. Over the 6 month follow-up period, 11 MACE occurred (3 strokes, 6 myocardial infarctions, 1 heart failure hospitalisation and 1 cardiovascular death), resulting in an incidence rate of 4.58 MACE per 100 person-years. Of participants completing 6 month follow-up, 31 (6.5%) reported a new non-communicable disease diagnosis, including 23 (4.8%) with a new hypertension diagnosis.

CONCLUSIONS

The incidence of MACE among PLWH in Tanzania is high. These findings are an important preliminary step in understanding the landscape of CVD among PLWH in Tanzania and highlight the need for interventions to reduce cardiovascular risk in this population.

A need to integrate healthcare services for HIV and non-communicable diseases: An Indian perspective

With the decline in HIV mortality, a concomitant increase in morbidity and death not directly related to HIV has been witnessed. Consequently, many countries especially low- and middle-income countries (LMICs) are now facing the dual burden of HIV and non-communicable diseases (NCDs). 2.3 million people living with HIV in India are at a higher risk of developing NCDs due to ageing, which can be attributed to the additional impact of long-standing HIV infection and the side-effects of antiretroviral therapy. This has led to a rise in demand for a combined health system response for managing HIV infection and co-existing NCDs, especially in LMICs such as India. The health and wellness centres (HWCs) envisioned to provide an expanded range of preventive and curative services including that for chronic conditions may act as a window of opportunity for providing egalitarian and accessible primary care services to these individuals. The reasons for integrating HIV and NCD care are epidemiological overlap between these conditions and the similar strategies required for provision of healthcare services.

Barriers and Facilitators to Utilization of Community Drug Distribution Points Among People Living with HIV in Bushenyi District, South-Western Uganda: A Qualitative Study

Introduction

People living with HIV (PLHIV) still have challenges in accessing HIV services in low- and middle-income countries (LMIC). In Uganda, community drug distribution points (CDDPs) are part of interventions to improve access to anti-retroviral medications. However, there is still low enrollment in CDDPs among PLHIV in south-western Uganda, particularly in Bushenyi district. This study explored the barriers and facilitators to the utilization of CDDPs among PLHIV.

Methods

This was a descriptive qualitative study utilizing a qualitative approach. We purposively recruited 24 PLHIV and 6 Primary healthcare providers as key informants. We conducted in-depth interviews with PLHIV and key informant interviews with Primary healthcare providers using an interview guide. The audio recordings were transcribed verbatim to Rukiga-Runyankore and then translated into English. Data were coded and analyzed using thematic analysis.

Results

Seven themes were developed describing drivers for the utilization of CDDPs. These were broadly categorized into facilitators and barriers. The main facilitators of the utilization of CDDPs were peer support, positive Primary healthcare providers' attitudes, satisfaction with HIV services, and accessibility of ART services. The main barriers were stigma, lack of physical infrastructure, and lack of comprehensive services.

Conclusion and Recommendation

Utilization of CDDPs is facilitated by accessibility and Primary healthcare providers' attitude. Stigma is still a limitation to the utilization of HIV services. We recommend that Ministry of Health and other development partners should improve physical infrastructural facilities at the CDDP sites so that the privacy and confidentiality of the PLHIV are protected. Focus on interventions to eliminate stigma by Primary healthcare providers and other stakeholders at CDDP sites is urgently needed.

Six-month incidence of hypertension and diabetes among adults with HIV in Tanzania: A prospective cohort study

Data describing the incidence of hypertension and diabetes among people with HIV in sub-Saharan Africa remain sparse. In this study, adults with HIV were enrolled from a public clinic in Moshi, Tanzania (September 2020-March 2021). At enrollment, a survey was administered to collect information on comorbidities and medication use. Each participant's blood pressure and point-of-care glucose were measured. Baseline hypertension was defined by blood pressure ≥140/90 mmHg or self-reported hypertension at enrollment. Baseline diabetes was defined by self-reported diabetes or hyperglycemia (fasting glucose ≥126 mg/dl or random glucose ≥200 mg/dl) at enrollment. At 6-month follow-up, participants' blood pressure and point-of-care glucose were again measured. Incident hypertension was defined by self-report of new hypertension diagnosis or blood pressure ≥140/90 mmHg at follow-up in a participant without baseline hypertension. Incident diabetes was defined as self-report of new diabetes diagnosis or measured hyperglycemia at follow-up in a participant without baseline diabetes. During the study period, 477 participants were enrolled, of whom 310 did not have baseline hypertension and 457 did not have baseline diabetes. At six-month follow-up, 51 participants (95% CI: 38, 67) had new-onset hypertension, corresponding to an incidence of 33 new cases of hypertension per 100 person-years. Participants with incident hypertension at 6-month follow-up were more likely to have a history of alcohol use (90.2% vs. 73.7%, OR = 3.18, 95% CI:1.32-9.62, p = 0.008) and were older (mean age = 46.5 vs. 42.3, p = 0.027). At six-month follow-up, 8 participants (95% CI: 3, 16) had new-onset diabetes, corresponding to an incidence of 3 new cases of diabetes per 100 person-years. In conclusion, the incidence of elevated blood pressure and diabetes among Tanzanians with HIV is higher than what has been reported in high-income settings.

Integrating global HIV services with primary health care: a key step in sustainable HIV epidemic control

Ending the HIV epidemic relies in part on integrating stand-alone HIV programming with primary health-care platforms to improve population-level health and ensure sustainability. Integration of HIV and primary health care services in sub-Saharan Africa improves both outcomes. Existing models support both integrating primary health care services into existing HIV services, and incorporating HIV services into primary health care platforms, with optimal programming based on local contexts and local epidemic factors. Person-centred differentiated service delivery, community-based interventions, and a well supported health workforce form the backbone of successful integration. Strategic financing to optimise HIV and primary health care integration requires well-coordinated partnerships with host governments, private sector companies, multilateral stakeholders, development banks, and non-government organisations. Programme success will require increased flexibility of international donors' implementation guidance as well as involvement of local communities and civil society organisations. As we seek to end the HIV epidemic by 2030 amidst a constrained global economic climate, integration of HIV programming with primary health care offers an avenue of opportunity and hope.

Person-centred, integrated non-communicable disease and HIV decentralized drug distribution in Eswatini and South Africa: outcomes and challenges

INTRODUCTION

Non-communicable diseases (NCDs) are highly prevalent in people living with HIV above 50 years of age and account for increasing mortality. There is little published evidence supporting person-centred, integrated models of HIV care, hypertension and diabetes treatment in southern Africa, and no data demonstrating mortality reduction. Where clinical visits for NCDs and HIV cannot be combined, integrated medication delivery presents an opportunity to streamline care and reduce patient costs. We present experiences of integrated HIV and NCD medication delivery in Eswatini and South Africa, focusing on programme successes and implementation challenges. Programmatic data from Eswatini's Community Health Commodities Distribution (CHCD) from April 2020 to December 2021 and South Africa's Central Chronic Medicines Dispensing and Distribution (CCMDD) from January 2016 to December 2021 were provided by programme managers and are summarized here.

DISCUSSION

Launched in 2020, Eswatini's CHCD provides over 28,000 people with and without HIV with integrated services, including HIV testing, CD4 cell count testing, antiretroviral therapy refills, viral load monitoring and pre-exposure prophylaxis alongside NCD services, including blood pressure and glucose monitoring and hypertension and diabetes medication refills.  Communities designate neighbourhood care points and central gathering places for person-centred medication dispensing.  This programme reported fewer missed medication refill appointments among clients in community settings compared to facility-based settings. South Africa's CCMDD utilizes decentralized drug distribution to provide medications for over 2.9 million people, including those living with HIV, hypertension and diabetes.  CCMDD incorporates community-based pickup points, facility "fast lanes" and adherence clubs with public sector health facilities and private sector medication collection units.  There are no out-of-pocket payments for medications or testing commodities.  Wait-times for medication refills are lower at CCMDD sites than facility-based sites.  Innovations to reduce stigma include uniformly labelled medication packages for NCD and HIV medications.

CONCLUSIONS

Eswatini and South Africa demonstrate person-centred models for HIV and NCD integration through decentralized drug distribution. This approach adapts medication delivery to serve individual needs and decongest centralized health facilities while efficiently delivering NCD care.  To bolster programme uptake, additional reporting of integrated decentralized drug distribution models should include HIV and NCD outcomes and mortality trends.

Global Health Perspectives on Race in Research: Neocolonial Extraction and Local Marginalization

Best practices in global health training prioritize leadership and engagement from investigators from low- and middle-income countries (LMICs), along with conscientious community consultation and research that benefits local participants and autochthonous communities. However, well into the 20th century, international research and clinical care remain rife with paternalism, extractive practices, and racist ideation, with race presumed to explain vulnerability or protection from various diseases, despite scientific evidence for far more precise mechanisms for infectious disease. We highlight experiences in global research on health and illness among indigenous populations in LMICs, seeking to clarify what is both scientifically essential and ethically desirable in research with human subjects; we apply a critical view towards race and racism as historically distorting elements that must be acknowledged and overcome.

Organizational readiness to implement task-strengthening strategy for hypertension management among people living with HIV in Nigeria

BACKGROUND

Hypertension (HTN) is highly prevalent among people living with HIV (PLHIV), but there is limited access to standardized HTN management strategies in public primary healthcare facilities in Nigeria. The shortage of trained healthcare providers in Nigeria is an important contributor to the increased unmet need for HTN management among PLHIV. Evidence-based TAsk-Strengthening Strategies for HTN control (TASSH) have shown promise to address this gap in other resource-constrained settings. However, little is known regarding primary health care facilities' capacity to implement this strategy. The objective of this study was to determine primary healthcare facilities' readiness to implement TASSH among PLHIV in Nigeria.

METHODS

This study was conducted with purposively selected healthcare providers at fifty-nine primary healthcare facilities in Akwa-Ibom State, Nigeria. Healthcare facility readiness data were measured using the Organizational Readiness to Change Assessment (ORCA) tool. ORCA is based on the Promoting Action on Research Implementation in Health Services (PARIHS) framework that identifies evidence, context, and facilitation as the key factors for effective knowledge translation. Quantitative data were analyzed using descriptive statistics (including mean ORCA subscales). We focused on the ORCA context domain, and responses were scored on a 5-point Likert scale, with 1 corresponding to disagree strongly.

FINDINGS

Fifty-nine healthcare providers (mean age 45; standard deviation [SD]: 7.4, 88% female, 68% with technical training, 56% nurses, 56% with 1-5 years providing HIV care) participated in the study. Most healthcare providers provide care to 11-30 patients living with HIV per month in their health facility, with about 42% of providers reporting that they see between 1 and 10 patients with HTN each month. Overall, staff culture (mean 4.9 [0.4]), leadership support (mean 4.9 [0.4]), and measurement/evidence-assessment (mean 4.6 [0.5]) were the topped-scored ORCA subscales, while scores on facility resources (mean 3.6 [0.8]) were the lowest.

CONCLUSION

Findings show organizational support for innovation and the health providers at the participating health facilities. However, a concerted effort is needed to promote training capabilities and resources to deliver services within these primary healthcare facilities. These results are invaluable in developing future strategies to improve the integration, adoption, and sustainability of TASSH in primary healthcare facilities in Nigeria.

High blood pressure and associated factors among HIV-infected young persons aged 13 to 25 years at selected health facilities in Rwenzori region, western Uganda, September-October 2021

BACKGROUND

High blood pressure (HBP), including hypertension (HTN), is a predictor of cardiovascular events, and is an emerging challenge in young persons. The risk of cardiovascular events may be further amplified among people living with HIV (PLHIV). We determined the prevalence of HBP and associated factors among PLHIV aged 13 to 25 years in Rwenzori region, western Uganda.

METHODS

We conducted a cross-sectional study among PLHIV aged 13 to 25 years at nine health facilities in Kabarole and Kasese districts during September 16 to October 15, 2021. We reviewed medical records to obtain clinical and demographic data. At a single clinic visit, we measured and classified BP as normal (< 120/ < 80 mmHg), elevated (120/ < 80 to 129/ < 80), stage 1 HTN (130/80 to 139/89), and stage 2 HTN (≥ 140/90). We categorized participants as having HBP if they had elevated BP or HTN. We performed multivariable analysis using modified Poisson regression to identify factors associated with HBP.

RESULTS

Of the 1,045 PLHIV, most (68%) were female and the mean age was 20 (3.8) years. The prevalence of HBP was 49% (n = 515; 95% confidence interval [CI], 46%-52%), the prevalence of elevated BP was 22% (n = 229; 95% CI, 26%-31%), and the prevalence of HTN was 27% (n = 286; 95% CI, 25%-30%), including 220 (21%) with stage 1 HTN and 66 (6%) with stage 2 HTN. Older age (adjusted prevalence ratio [aPR], 1.21; 95% CI, 1.01-1.44 for age group of 18-25 years vs. 13-17 years), history of tobacco smoking (aPR, 1.41; 95% CI, 1.08-1.83), and higher resting heart rate (aPR, 1.15; 95% CI, 1.01-1.32 for > 76 beats/min vs. ≤ 76 beats/min) were associated with HBP.

CONCLUSIONS

Nearly half of the PLHIV evaluated had HBP, and one-quarter had HTN. These findings highlight a previously unknown high burden of HBP in this setting's young populations. HBP was associated with older age, elevated resting heart rate, and ever smoking; all of which are known traditional risk factors for HBP in HIV-negative persons. To prevent future cardiovascular disease epidemics among PLHIV, there is a need to integrate HBP/HIV management.

A Conceptual Model to Strengthen Integrated Management of HIV and NCDs among NIMART-Trained Nurses in Limpopo Province, South Africa

Integrated management of human immune deficiency virus (HIV) and non-communicable diseases (NCDs) in primary health care facilities remains a challenge. Despite research that has been conducted in South Africa, it is evident that in Limpopo Province there are slits in the implementation thereof. There is a need to develop a conceptual model to guide in strengthening the clinical competence of nurse-initiated management of antiretroviral therapy (NIMART)-trained nurses to implement the integrated management of HIV and NCDs to improve clinical outcomes of patients with the dual burden of diseases in Limpopo Province, South Africa. This study aimed to develop a conceptual model to strengthen the implementation of integrated management of HIV and NCDs amongst NIMART nurses to improve clinical outcomes of patients with the dual burden of communicable and non-communicable diseases in Limpopo Province, South Africa. An explanatory, sequential, mixed-methods research design was followed. Data were collected from patient records and the skills audit of 25 Primary Health Care (PHC) facilities and from 28 NIMART trained nurses. Donabedian's structure process outcome model and Miller's pyramid of clinical competence provided a foundation in the development of the conceptual model. The study revealed a need to develop a conceptual model to strengthen the implementation of integrated HIV and NCDs implementation in PHC, as evidenced by differences in the management of HIV and NCDs. Conclusion: The study findings were conceptualised to describe and develop a model needed to strengthen the implementation of integrated management of HIV and NCDs amongst NIMART nurses working in PHC facilities. The study was limited to Limpopo Province; the model must be implemented in conjunction with the available frameworks to achieve better clinical outcomes.

Descriptive study: Feasibility of integrating hypertension screening into HIV assisted partner notification services model in Kenya

Prevalence of hypertension (HTN) and human immunodeficiency virus (HIV) are high among men while screening rates are low. Assisted partner notification service is a strategy recommended by the World Health Organization that aims to increase HIV testing and treatment uptake and may present an opportunity to offer integrated HIV/HTN screening and treatment services. In this prospective cohort study, we assessed the feasibility of integrating HTN screening for male sexual partners of females newly tested HIV-positive in 10 health facilities in Kenya. Participants were notified of the exposure and offered HIV testing and HTN screening; if they accepted and tested positive for either HTN, HIV, or both, they were referred for care. HTN was defined as systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90, or the use of antihypertensive medication. Among 1313 male partners traced, 99% accepted HIV testing and HTN screening. Overall, 4% were found to have HTN, 29% were in the pre-HTN stage, and 9% were HIV-positive. Only 75% had previously been screened for HTN compared to 95% who had previously tested for HIV. A majority preferred non-facility-based screening. The participants who refused HTN screening noted time constraints as a significant hindrance. HIV and HTN screening uptake was high in this hard-to-reach population of men aged 25 to 50. Although HTN rates were low, an integrated approach provided an opportunity to detect those with pre-HTN and intervene early. Strategic integration of HTN services within assisted partners services may promote and normalize testing by offering inclusive and accessible services to men.

Patient priority setting in HIV ageing research: exploring the feasibility of community engagement and involvement in Tanzania

OBJECTIVE

The chronic complications of ageing with HIV are not well studied in sub-Saharan Africa (SSA) where general healthcare resources are limited. We aimed to collaborate with individuals living with HIV aged ≥ 50 years, and community elders (aged ≥ 60 years) living with non-communicable diseases in the Kilimanjaro region of Tanzania in a health research priority-setting exercise.

METHODS

We conducted structured workshops based on broad questions to aid discussion and group-based patient priority setting, alongside discussion of the feasibility of future community research engagement. Participant priorities were tallied and ranked to arrive at core priorities from consensus discussion.

RESULTS

Thirty older people living with HIV and 30 community elders attended separate priority setting workshops. Both groups reported motivation to participate in, conduct, and oversee future studies. In this resource-limited setting, basic needs such as healthcare access were prioritised much higher than specific HIV-complications or chronic disease. Stigma and social isolation were highly prioritised in those living with HIV.

CONCLUSIONS

Community engagement and involvement in HIV and ageing research appears feasible in Tanzania. Ageing and non-communicable disease research should consider the wider context, and lack of basic needs in low-income settings. A greater impact may be achieved with community involvement.

Integrated Care as a Model for Interprofessional Disease Management and the Benefits for People Living with HIV/AIDS

INTRODUCTION

Today, antiretroviral therapy (ART) is effectively used as a lifelong therapy to treat people living with HIV (PLWH) to suppress viral replication. Moreover, PLWH need an adequate care strategy in an interprofessional, networked setting of health care professionals from different disciplines. HIV/AIDS poses challenges to both patients and health care professionals within the framework of care due to frequent visits to physicians, avoidable hospitalizations, comorbidities, complications, and the resulting polypharmacy. The concepts of integrated care (IC) represent sustainable approaches to solving the complex care situation of PLWH.

AIMS

This study aimed to describe the national and international models of integrated care and their benefits regarding PLWH as complex, chronically ill patients in the health care system.

METHODS

We conducted a narrative review of the current national and international innovative models and approaches to integrated care for people with HIV/AIDS. The literature search covered the period between March and November 2022 and was conducted in the databases Cinahl, Cochrane, and Pubmed. Quantitative and qualitative studies, meta-analyses, and reviews were included.

RESULTS

The main findings are the benefits of integrated care (IC) as an interconnected, guideline- and pathway-based multiprofessional, multidisciplinary, patient-centered treatment for PLWH with complex chronic HIV/AIDS. This includes the evidence-based continuity of care with decreased hospitalization, reductions in costly and burdensome duplicate testing, and the saving of overall health care costs. Furthermore, it includes motivation for adherence, the prevention of HIV transmission through unrestricted access to ART, the reduction and timely treatment of comorbidities, the reduction of multimorbidity and polypharmacy, palliative care, and the treatment of chronic pain. IC is initiated, implemented, and financed by health policy in the form of integrated health care, managed care, case and care management, primary care, and general practitioner-centered concepts for the care of PLWH. Integrated care was originally founded in the United States of America. The complexity of HIV/AIDS intensifies as the disease progresses.

CONCLUSIONS

Integrated care focuses on the holistic view of PLWH, considering medical, nursing, psychosocial, and psychiatric needs, as well as the various interactions among them. A comprehensive expansion of integrated care in primary health care settings will not only relieve the burden on hospitals but also significantly improve the patient situation and the outcome of treatment.

A new era of HIV care for age-associated multimorbidity

PURPOSE OF REVIEW

The management of people with HIV has shifted focus from acute AIDS-defining illness towards improving detection of chronic disease and reducing impact of multimorbidity. In this review, we explore this shifting paradigm of HIV care and the evidence for alternative models proposed to provide integrated holistic services for people with HIV (PWH) with multimorbidity.

RECENT FINDINGS

Despite 25 years of the antiretroviral treatment (ART) era an increased incidence of noncommunicable disease (NCD) and multimorbidity in PWH persists. As the world moves closer to universal ART coverage this phenomenon is now reported in low- and middle-income settings. Multimorbidity affects PWH disproportionately compared to the general population and results in reduced health related quality of life (HRQoL), greater hospitalization and higher mortality. There is evidence that NCD care provision and outcomes may be inferior for PWH than their HIV negative counterparts. Various models of integrated multimorbidity care have developed and are grouped into four categories; HIV specialist clinics incorporating NCD care, primary care services incorporating HIV care, community NCD clinics offering integrated HIV care, and multidisciplinary care integrated with HIV in secondary care. Evidence is limited as to the best way to provide multimorbidity care for PWH.

SUMMARY

A new era of HIV care for an ageing population with multimorbidity brings challenges for health providers who need to develop holistic patient focused services which span a range of coexisting conditions.

"After all, we are all sick": multi-stakeholder understanding of stigma associated with integrated management of HIV, diabetes and hypertension at selected government clinics in Uganda

BACKGROUND

Integrated care is increasingly used to manage chronic conditions. In Uganda, the integration of HIV, diabetes and hypertension care has been piloted, to leverage the advantages of well facilitated and established HIV health care provision structures. This qualitative study aimed to explore HIV stigma dynamics whilst investigating multi-stakeholder perceptions and experiences of providing and receiving integrated management of HIV, diabetes and hypertension at selected government clinics in Central Uganda.  METHODS: We adopted a qualitative-observational design. Participants were purposively selected. In-depth interviews were conducted with patients and with health care providers, clinical researchers, policy makers, and representatives from international nongovernmental organizations (NGOs). Focus group discussions were conducted with community members and leaders. Clinical procedures in the integrated care clinic were observed. Data were managed using Nvivo 12 and analyzed thematically.

RESULTS

Triangulated findings revealed diverse multi-stakeholder perceptions around HIV related stigma. Integrated care reduced the frequency with which patients with combinations of HIV, diabetes, hypertension visited health facilities, reduced the associated treatment costs, increased interpersonal relationships among patients and healthcare providers, and increased the capacity of health care providers to manage multiple chronic conditions. Integration reduced stigma through creating opportunities for health education, which allayed patient fears and increased their resolve to enroll for and adhere to treatment. Patients also had an opportunity to offer and receive psycho-social support and coupled with the support they received from healthcare worker. This strengthened patient-patient and provider-patient relationships, which are building blocks of service integration and of HIV stigma reduction. Although the model significantly reduced stigma, it did not eradicate service level challenges and societal discrimination among HIV patients.

CONCLUSION

The study reveals that, in a low resource setting like Uganda, integration of HIV, diabetes and hypertension care can improve patient experiences of care for multiple chronic conditions, and that integrated clinics may reduce HIV related stigma.

Leveraging the HIV response to strengthen pandemic preparedness

The COVID-19 pandemic and the expectation of future pandemic threats have generated a global dialogue on strengthening pandemic preparedness and response (PPR). Thus far, this dialogue has largely failed to fully consider the critical role that established, disease-specific programs played in national and regional COVID-19 responses, and the potential for these programs to contribute to stronger pandemic preparedness for the future. The HIV response is an important example of a global health initiative that is already making substantial contributions to PPR. Both the infrastructure and core principles of the HIV response have much to contribute towards pandemic preparedness that is more effective and equitable than seen in the response to COVID-19. This review examines how HIV-related resources and principles can support communities and countries in being better prepared for emerging disease threats, with a specific focus on evidence from the COVID-19 pandemic. Drawing on the current literature, the review explores the clear, multi-faceted intersection between the HIV response and the central elements of pandemic preparedness in areas including surveillance; supply chain; primary care; health care workforce; community engagement; biomedical research; universal access without discrimination; political leadership; governance; and financing. There are many opportunities to be more strategic and purposeful in leveraging HIV programs and approaches for preparedness. Avoiding the longstanding temptation in global health to create new siloes, PPR initiatives, including the new Pandemic Fund at the World Bank, should invest in and build out from existing programs that are already making health systems more inclusive and resilient, including the global response to HIV.

An evaluation of the disparities affecting the underdiagnosis of pediatric cancer in Western Kenya

INTRODUCTION

Western Kenya is home to approximately 24 million people, with 10 million children under the age of 15 years.¹ Based on estimates of cancer incidence in similar populations from around the world, approximately 1500 patients should be diagnosed with pediatric cancer each year. This article describes the international collaboration that investigates potential barriers preventing the effective diagnosis of pediatric patients with cancer.

METHODS

Here, we describe a multidisciplinary and sequential approach to better evaluate the complex factors affecting the lack of appropriate diagnosis of pediatric cancer in Western Kenya.

RESULTS

Internal review at a large tertiary hospital noted 200-250 patients were diagnosed annually, suggesting the remaining 75%-80% of patients go undiagnosed and do not receive treatment. Following our screening process at a local referring hospital, 41 malaria slides demonstrated both morphologic and genetic evidence of leukemia. Knowledge assessments of local providers at referring institutions suggested a lack of education and training as the factors that contribute to lower rates of diagnosis.

DISCUSSION

Through a multi-step approach, our teams were better able to isolate potential issues impeding the appropriate and timely diagnosis of pediatric cancer in Kenya.

Stakeholder perspectives around post-TB wellbeing and care in Kenya and Malawi

BACKGROUND

There is growing awareness of the burden of post-TB morbidity, and its impact on the lives and livelihoods of TB affected households. However little work has been done to determine how post-TB care might be delivered in a feasible and sustainable way, within existing National TB Programmes (NTPs) and health systems, in low-resource, high TB-burden settings. In this programme of stakeholder engagement around post-TB care, we identified actors with influence and interest in TB care in Kenya and Malawi, including TB-survivors, healthcare providers, policy-makers, researchers and funders, and explored their perspectives on post-TB morbidity and care.

METHODS

Stakeholder mapping was completed to identify actors with interest and influence in TB care services in each country, informed by the study team's local, regional and international networks. Key international TB organisations were included to provide a global perspective. In person or online one-to-one interviews were completed with purposively selected stakeholders. Snowballing was used to expand the network. Data were recorded, transcribed and translated, and a coding frame was derived. Data were coded using NVivo 12 software and were analysed using thematic content analysis. Online workshops were held with stakeholders from Kenya and Malawi to explore areas of uncertainty and validate findings.

RESULTS

The importance of holistic care for TB patients, which addresses both TB comorbidities and sequelae, was widely recognised by stakeholders. Key challenges to implementation include uncertainty around the burden of post-TB morbidity, leadership of post-TB services, funding constraints, staff and equipment limitations, and the need for improved integration between national TB and non-communicable disease (NCD) programmes for care provision and oversight. There is a need for local data on the burden and distribution of morbidity, evidence-informed clinical guidelines, and pilot data on models of care. Opportunities to learn from existing HIV-NCD services were emphasised.

DISCUSSION

This work addresses important questions about the practical implementation of post-TB services in two African countries, exploring if, how, where, and for whom these services should be provided, according to a broad range of stakeholders. We have identified strong interest in the provision of holistic care for TB patients in Kenya and Malawi, and key evidence gaps which must be addressed to inform decision making by policy makers, TB programmes, and funders around investment in post-TB services. There is a need for pilot studies of models of integrated TB care, and for cross-learning between countries and from HIV-NCD services.

Models of lifelong care for children and adolescents with chronic conditions in low-income and middle-income countries: a scoping review

Globally, non-communicable diseases (NCDs) or chronic conditions account for one-third of disability-adjusted life-years among children and adolescents under the age of 20. Health systems must adapt to respond to the growing burden of NCDs among children and adolescents who are more likely to be marginalised from healthcare access and are at higher risk for poor outcomes. We undertook a review of recent literature on existing models of chronic lifelong care for children and adolescents in low-income and middle-income countries with a variety of NCDs and chronic conditions to summarise common care components, service delivery approaches, resources invested and health outcomes.

Factors influencing the integration of evidence-based task-strengthening strategies for hypertension control within HIV clinics in Nigeria

Background

Evidence-based task-strengthening strategies for hypertension (HTN) control (TASSH) are not readily available for patients living with HIV in sub-Saharan Africa where the dual burden of HTN and HIV remains high. We are conducting a cluster randomized controlled trial comparing the effectiveness of practice facilitation versus a self-directed control (i.e., receipt of TASSH with no practice facilitation) in reducing blood pressure and increasing the adoption of task-strengthening strategies for HTN control within HIV clinics in Nigeria. Prior to implementing the trial, we conducted formative research to identify factors that may influence the integration of TASSH within HIV clinics in Nigeria.

Methods

This mixed-methods study was conducted with purposively selected healthcare providers at 29 HIV clinics, followed by a 1-day stakeholder meeting with 19 representatives of HIV clinics. We collected quantitative practice assessment data using two instruments: (a) an adapted Service Availability and Readiness Assessment (SARA) tool to assess the capacity of the clinic to manage NCDs and (b) Implementation Climate Scale to assess the degree to which there is a strategic organizational climate supportive of the evidence-based practice implementation. The quantitative data were analyzed using descriptive statistics and measures of scale reliability. We also used the Consolidated Framework for Implementation Research (CFIR), to thematically analyze qualitative data generated and relevant to the aims of this study.

Results

Across the 29 clinics surveyed, the focus on TASSH (mean=1.77 (SD=0.59)) and educational support (mean=1.32 (SD=0.68)) subscales demonstrated the highest mean score, with good–excellent internal consistency reliability (Cronbach’s alphas ranging from 0.84 to 0.96). Within the five CFIR domains explored, the major facilitators of the intervention included relative advantage of TASSH compared to current practice, compatibility with clinic organizational structures, support of patients’ needs, and intervention alignment with national guidelines. Barriers included the perceived complexity of TASSH, weak referral network and patient tracking mechanism within the clinics, and limited resources and diagnostic equipment for HTN.

Conclusion

Optimizing healthcare workers’ implementation of evidence-based TASSH within HIV clinics requires attention to both the implementation climate and contextual factors likely to influence adoption and long-term sustainability. These findings have implications for the development of effective practice facilitation strategies to further improve the delivery and integration of TASSH within HIV clinics in Nigeria.

Hypertension among adults enrolled in HIV care in northern Tanzania: comorbidities, cardiovascular risk, and knowledge, attitudes and practices

Cite this article

Preeti Manavalan et al. Hypertension among adults enrolled in HIV care in northern Tanzania: comorbidities, cardiovascular risk, and knowledge, attitudes and practices. Pan African Medical Journal. 2022;41(285). 10.11604/pamj.2022.41.285.26952.

Introduction

the epidemiology of non-communicable diseases (NCDs) among people living with HIV (PLHIV) in sub-Saharan Africa is poorly described. In this observational study we examined a cohort of hypertensive PLHIV in northern Tanzania and described comorbidities, cardiovascular risk, and hypertension knowledge, attitudes and practices.

Methods

consecutive patients attending an HIV clinic were screened for hypertension; those who met hypertension study criteria were enrolled. Participants completed a hypertension knowledge, attitudes and practices survey, and underwent height, weight, and waist circumference measurements and urine dipstick, fasting blood sugar, and lipid panel analyses. Kidney disease was defined as 1+ proteinuria, diabetes mellitus was defined as fasting glucose >126mg/dL, and 10-year atherosclerotic cardiovascular disease (ASCVD) risk was defined per the Pooled Cohorts Equations.

Results

of 555 screened patients, 105 met hypertension criteria and 91 (86.7%) were enrolled. The prevalence of diabetes mellitus, kidney disease, and overweight or obesity was 8.8%, 28.6%, and 86.7%, respectively. Almost all participants (n=86, 94.5%) had two or more medical comorbidities. More than half (n=39, 52.7%) had intermediate or high 10-year risk for an ASCVD event. While only 3 (3.3%) participants were able to define hypertension correctly, most would seek care at a medical facility (n=89, 97.8%) and take medication chronically for hypertension (n=79, 87.8%).

Conclusion

we found a high burden of medical comorbidity and ASCVD risk among hypertensive PLHIV in northern Tanzania. Integration of routine NCD screening in the HIV clinical setting, in combination with large-scale educational campaigns, has the potential to impact clinical outcomes in this high-risk population.

How health systems can adapt to a population ageing with HIV and comorbid disease

As people age with HIV, their needs increase beyond solely managing HIV care. Ageing people with HIV, defined as people with HIV who are 50 years or older, face increased risk of both age-regulated comorbidities and ageing-related issues. Globally, health-care systems have struggled to meet these changing needs of ageing people with HIV. We argue that health systems need to rethink care strategies to meet the growing needs of this population and propose models of care that meet these needs using the WHO health system building blocks. We focus on care provision for ageing people with HIV in the three different funding mechanisms: President's Emergency Plan for AIDS Relief and Global Fund funded nations, the USA, and single-payer government health-care systems. Although our categorisation is necessarily incomplete, our efforts provide a valuable contribution to the debate on health systems strengthening as the need for integrated, people-centred, health services increase.

Type 2 diabetes mellitus in sub-Saharan Africa: challenges and opportunities

Type 2 diabetes mellitus (T2DM), which was once thought to be rare in sub-Saharan Africa (SSA), is now well established in this region. The SSA region is undergoing a rapid but variable epidemiological transition fuelled by the pace of urbanization, with disease burden profiles shifting from communicable diseases to non-communicable diseases (NCDs). Information on the epidemiology of T2DM has increased, but wide variations in study methods, diagnostic biomarkers and criteria hamper analytical comparison, and data from high-quality studies are limited. The prevalence of T2DM is still low in some rural populations but moderate or high rates are reported in many countries/regions, with evidence for an increase in some. In addition, the proportion of undiagnosed T2DM is still high. The prevalence of T2DM is highest in African people living in urban areas, and the gradient between African people living in urban areas and people in the African diaspora is rapidly fading. However, data from longitudinal studies are lacking and there is limited information on chronic complications and the genetics of T2DM. The large unmet needs for T2DM care call for greater investment of resources into health systems to manage NCDs in SSA. Proposed health-system paradigms are being developed in some countries/regions. However, national NCD programmes need to be adequately funded and coordinated to stem the tide of T2DM and its complications.

Non-communicable disease co-morbidity and associated factors in tuberculosis patients: A cross-sectional study in Gabon

BACKGROUND

There are only limited data from resource-limited settings available on the prevalence of non-communicable diseases and associated risk factors of tuberculosis patients. This study investigated non-communicable disease co-morbidity in tuberculosis patients from Moyen Ogooué Province, Gabon.

METHODS

All patients aged 18 years or older consulting for tuberculosis (TB) symptoms in Gabon's Moyen Ogooué province and neighbouring provinces from November 2018 to November 2020 were screened for diabetes mellitus, hypertension, and risk factors thereof (obesity, dyslipidaemia, smoking and alcohol consumption). Logistic regression was performed to identify factors associated with TB-diabetes and TB-hypertension co-morbidities.

FINDINGS

Of 583 patients included, 227 (39%) were diagnosed with tuberculosis. In tuberculosis-confirmed patients, the prevalences of hypertension and diabetes were 16·3% and 12·8%, respectively. The prevalence of diabetes was twice as high in tuberculosis patients compared to non-tuberculosis patients. Factors independently associated with hypertension-tuberculosis co-morbidity were age >55 years (aOR=8·5, 95% CI 2·43, 32·6), age 45-54 years (aOR=4.9, 95%CI 1.3-19.8), and moderate alcohol consumption (aOR=2·4; 95% CI 1·02- 5·9), respectively. For diabetes-tuberculosis co-morbidity, age >55 years was positively (aOR=9·13; 95% CI 2·4-39·15), and moderate alcohol consumption inversely associated (aOR=0·26, 95% CI 0·08- 0·73). One-hundred-and-four (46%) of the tuberculosis patients had at least either dyslipidaemia, hypertension, diabetes, or obesity with a majority of newly-diagnosed hypertension and diabetes.

INTERPRETATION

Integration of screening of non-communicable diseases and their risk factors during TB assessment for early diagnosis, treatment initiation and chronic care management for better health outcomes should be implemented in all tuberculosis healthcare facilities.

FUNDING

This study was supported by WHO AFRO/TDR/EDCTP (2019/893,805) and Deutsches Zentrum für Infektiologie (DZIF/ TTU 02.812).

Multimorbidity of communicable and non-communicable diseases in low- and middle-income countries: A systematic review

OBJECTIVE

The aim of this systematic review is to analyse existing evidence on prevalence, patterns, determinants, and healthcare challenges of communicable and non-communicable disease multimorbidity in low- and middle-income countries (LMICs).

METHODS

PubMed, Cochrane, and Embase databases were searched from 1^st January 2000 to 31^st July 2020. The National Institute of Health (NIH) quality assessment tool was used to critically appraise studies. Findings were summarized in a narrative synthesis. The review was registered with PROSPERO (CRD42019133453).

RESULTS

Of 3718 articles screened, 79 articles underwent a full text review of which 11 were included for narrative synthesis. Studies reported on 4 to 20 chronic communicable and non-communicable diseases; prevalence of multimorbidity ranged from 13% in a study conducted among 242,952 participants from 48 LMICS to 87% in a study conducted among 491 participants in South Africa. Multimorbidity was positively associated with older age, female sex, unemployment, and physical inactivity. Significantly higher odds of multimorbidity were noted among obese participants (OR 2.33; 95% CI: 2.19-2.48) and those who consumed alcohol (OR 1.44; 95% CI: 1.25-1.66). The most frequently occurring dyads and triads were HIV and hypertension (23.3%) and HIV, hypertension, and diabetes (63%), respectively. Women and participants from low wealth quintiles reported higher utilization of public healthcare facilities.

CONCLUSION

The identification and prevention of risk factors and addressing evidence gaps in multimorbidity clustering is crucial to address the increasing communicable and non-communicable disease multimorbidity in LMICs. To identify communicable and non-communicable diseases trends over time and identify causal relationships, longitudinal studies are warranted.

Integrated healthcare services for HIV, diabetes mellitus and hypertension in selected health facilities in Kampala and Wakiso districts, Uganda: A qualitative methods study

Health policies in Africa are shifting towards integrated care services for chronic conditions, but in parts of Africa robust evidence on effectiveness is limited. We assessed the integration of vertical health services for HIV, diabetes and hypertension provided in a feasibility study within five health facilities in Uganda. From November 2018 to January 2020, we conducted a series of three in-depth interviews with 31, 29 and 24 service users attending the integrated clinics within Kampala and Wakiso districts. Ten healthcare workers were interviewed twice during the same period. Interviews were conducted in Luganda, translated into English, and analysed thematically using the concepts of availability, affordability and acceptability. All participants reported shortages of diabetes and hypertension drugs and diagnostic equipment prior to the establishment of the integrated clinics. These shortages were mostly addressed in the integrated clinics through a drugs buffer. Integration did not affect the already good provision of anti-retroviral therapy. The cost of transport reduced because of fewer clinic visits after integration. Healthcare workers reported that the main cause of non-adherence among users with diabetes and hypertension was poverty. Participants with diabetes and hypertension reported they could not afford private clinical investigations or purchase drugs prior to the establishment of the integrated clinics. The strengthening of drug supply for non-communicable conditions in the integrated clinics was welcomed. Most participants observed that the integrated clinic reduced feelings of stigma for those living with HIV. Sharing the clinic afforded privacy about an individual's condition, and users were comfortable with the waiting room sitting arrangement. We found that integrating non-communicable disease and HIV care had benefits for all users. Integrated care could be an effective model of care if service users have access to a reliable supply of basic medicines for both HIV and non-communicable disease conditions.

Patient perspectives on integrated healthcare for HIV, hypertension and type 2 diabetes: a scoping review

INTRODUCTION

Antiretroviral therapy has reduced mortality and led to longer life expectancy in people living with HIV. These patients are now at an increased risk of non-communicable diseases (NCDs). Integration of care for HIV and NCDs has become a focus of research and policy. In this article, we aim to review patient perspectives on integration of healthcare for HIV, type 2 diabetes and hypertension.

METHODS

The framework for scoping reviews developed by Arksey and O'Malley and updated by Peter et al was applied for this review. The databases PubMed, Web of Science and Cochrane library were searched. Broad search terms for HIV, NCDs (specifically type 2 diabetes and hypertension) and healthcare integration were used. As the review aimed to identify definitions of patient perspectives, they were not included as an independent term in the search strategy. References of included publications were searched for relevant articles. Titles and abstracts for these papers were screened by two independent reviewers. The full texts for all the publications appearing to meet the inclusion criteria were then read to make the final literature selection.

RESULTS

Of 5502 studies initially identified, 13 articles were included in this review, of which 11 had a geographical origin in sub-Saharan Africa. Nine articles were primarily focused on HIV/diabetes healthcare integration while four articles were focused on HIV/hypertension integration. Patient's experiences with integrated care were reduced HIV-related stigma, reduced travel and treatment costs and a more holistic person-centred care. Prominent concerns were long waiting times at clinics and a lack of continuity of care in some clinics due to a lack of healthcare workers. Non-integrated care was perceived as time-consuming and more expensive.

CONCLUSION

Patient perspectives and experiences on integrated care for HIV, diabetes and hypertension were mostly positive. Integrated services can save resources and allow for a more personalised approach to healthcare. There is a paucity of evidence and further longitudinal and interventional evidence from a more diverse range of healthcare systems are needed.

Integration of a task strengthening strategy for hypertension management into HIV care in Nigeria: a cluster randomized controlled trial study protocol

Background

In regions with weak healthcare systems, critical shortages of the healthcare workforce, and increasing prevalence of dual disease burdens, there is an urgent need for the implementation of proven effective interventions and strategies to address these challenges. Our mixed-methods hybrid type II effectiveness-implementation study is designed to fill this evidence-to-practice gap. This study protocol describes a cluster randomized controlled trial which evaluates the effectiveness of an implementation strategy, practice facilitation (PF), on the integration, adoption, and sustainability of a task-strengthening strategy for hypertension control (TASSH) intervention within primary healthcare centers (PHCs) in Lagos State, Nigeria.

Design

Guided by the Consolidated Framework for Implementation Research (CFIR) and the Reach Effectiveness Adoption Implementation and Maintenance (RE-AIM), this study tests the impact of a proven effective implementation strategy to integrate hypertension management into the HIV care cascade, across 30 PHCs. The study will be conducted in three phases: (1) a pre-implementation phase that will use CFIR to develop a tailored PF intervention for integrating TASSH into HIV clinics; (2) an implementation phase that will use RE-AIM to compare the clinical effectiveness of PF vs. a self-directed condition (receipt of information on TASSH without PF) on BP reduction; and (3) a post-implementation phase that will use RE-AIM to evaluate the effect of PF vs. self-directed condition on adoption and sustainability of TASSH. The PF intervention components comprise (a) an advisory board to provide leadership support for implementing TASSH in PHCs; (b) training of the HIV nurses on TASSH protocol; and (c) training of practice facilitators, who will serve as coaches, provide support, and performance feedback to the HIV nurses.

Discussion

This study is one of few, if any trials, to evaluate the impact of an implementation strategy for integrating hypertension management into HIV care, on clinical and implementation outcomes. Findings from this study will advance implementation science research on the effectiveness of tailoring an implementation strategy for the integration of an evidence-based, system-level hypertension control intervention into HIV care and treatment.

Integrating diabetes, hypertension and HIV care in sub-Saharan Africa: a Delphi consensus study on international best practice

Background

Although HIV continues to have a high prevalence among adults in sub-Saharan Africa (SSA), the burden of noncommunicable diseases (NCD) such as diabetes and hypertension is increasing rapidly. There is an urgent need to expand the capacity of healthcare systems in SSA to provide NCD services and scale up existing chronic care management pathways. The aim of this study was to identify key components, outcomes, and best practice in integrated service provision for the prevention, identification and treatment of HIV, hypertension and diabetes.

Methods

An international, multi stakeholder e-Delphi consensus study was conducted over two successive rounds. In Round 1, 24 participants were asked to score 27 statements, under the headings ‘Service Provision’ and ‘Benefits of Integration’, by importance. In Round 2, the 16 participants who completed Round 1 were shown the distribution of scores from other participants along with the score that they attributed to an outcome and were asked to reflect on the score they gave, based on the scores of the other participants and then to rescore if they wished to. Nine participants completed Round 2.

Results

Based on the Round 1 ranking, 19 of the 27 outcomes met the 70% threshold for consensus. Four additional outcomes suggested by participants in Round 1 were added to Round 2, and upon review by participants, 22 of the 31 outcomes met the consensus threshold. The five items participants scored from 7 to 9 in both rounds as essential for effective integrated healthcare delivery of health services for chronic conditions were improved data collection and surveillance of NCDs among people living with HIV to inform integrated NCD/HIV programme management, strengthened drug procurement systems, availability of equipment and access to relevant blood tests, health education for all chronic conditions, and enhanced continuity of care for patients with multimorbidity.

Conclusions

This study highlights the outcomes which may form key components of future complex interventions to define a model of integrated healthcare delivery for diabetes, hypertension and HIV in sub-Saharan Africa.

Integrating health services for HIV infection, diabetes and hypertension in sub-Saharan Africa: a cohort study

BACKGROUND

HIV, diabetes and hypertension have a high disease burden in sub-Saharan Africa. Healthcare is organised in separate clinics, which may be inefficient. In a cohort study, we evaluated integrated management of these conditions from a single chronic care clinic.

OBJECTIVES

To determined the feasibility and acceptability of integrated management of chronic conditions in terms of retention in care and clinical indicators.

DESIGN AND SETTING

Prospective cohort study comprising patients attending 10 health facilities offering primary care in Dar es Salaam and Kampala.

INTERVENTION

Clinics within health facilities were set up to provide integrated care. Patients with either HIV, diabetes or hypertension had the same waiting areas, the same pharmacy, were seen by the same clinical staff, had similar provision of adherence counselling and tracking if they failed to attend appointments.

PRIMARY OUTCOME MEASURES

Retention in care, plasma viral load.

FINDINGS

Between 5 August 2018 and 21 May 2019, 2640 patients were screened of whom 2273 (86%) were enrolled into integrated care (832 with HIV infection, 313 with diabetes, 546 with hypertension and 582 with multiple conditions). They were followed up to 30 January 2020. Overall, 1615 (71.1%)/2273 were female and 1689 (74.5%)/2266 had been in care for 6 months or more. The proportions of people retained in care were 686/832 (82.5%, 95% CI: 79.9% to 85.1%) among those with HIV infection, 266/313 (85.0%, 95% CI: 81.1% to 89.0%) among those with diabetes, 430/546 (78.8%, 95% CI: 75.4% to 82.3%) among those with hypertension and 529/582 (90.9%, 95% CI: 88.6 to 93.3) among those with multimorbidity. Among those with HIV infection, the proportion with plasma viral load <100 copies/mL was 423(88.5%)/478.

CONCLUSION

Integrated management of chronic diseases is a feasible strategy for the control of HIV, diabetes and hypertension in Africa and needs evaluation in a comparative study.

Leveraging HIV Care Infrastructures for Integrated Chronic Disease and Pandemic Management in Sub-Saharan Africa

In Sub-Saharan Africa, communicable and other tropical infectious diseases remain major challenges apart from the continuing HIV/AIDS epidemic. Recognition and prevalence of non-communicable diseases have risen throughout Africa, and the reimagining of healthcare delivery is needed to support communities coping with not only with HIV, tuberculosis, and COVID-19, but also cancer, cardiovascular disease, diabetes, and depression. Many non-communicable diseases can be prevented or treated with low-cost interventions, yet implementation of such care has been limited in the region. In this Perspective piece, we argue that deployment of an integrated service delivery model is an urgent next step, propose a South African model for integration, and conclude with recommendations for next steps in research and implementation. An approach that is inspired by South African experience would build on existing HIV-focused infrastructure that has been developed by Ministries of Health with strong support from the U.S. President’s Emergency Response for AIDS Relief (PEPFAR) and the Global Fund to Fight AIDS, Tuberculosis and Malaria. An integrated chronic healthcare model holds promise to sustainably deliver infectious disease and non-communicable disease care. Integrated care will be especially critical as health systems seek to cope with the unprecedented challenges associated with COVID-19 and future pandemic threats.

Integrating Sexual and Reproductive Health Services Within HIV Services: WHO Guidance

Among the 1.9 billion women of reproductive age worldwide in 2019, 1.1 billion need family planning and 270 million have an unmet need for contraception. For women and adolescent girls living with human immunodeficiency virus (HIV), using effective contraception reduces the mother-to-child transmission of HIV by preventing unintended pregnancies and enabling the planning and safer conception of desired pregnancies with optimal maternal and child health outcomes. The World Health Organization (WHO) recommends that sexual and reproductive health services, including contraception, may be integrated within HIV services. Integration is associated with increased offers and uptake of sexual and reproductive health services, including contraception, which is likely to result in improved downstream clinical outcomes. Integrating HIV and sexual and reproductive health services has been found to improve access, the quality of antenatal care and nurse productivity while reducing stigma and without compromising uptake of care. Research is encouraged to identify approaches to integration that lead to better uptake of sexual and reproductive health services, including contraception. Implementation research is encouraged to evaluate different strategies of integration in different health systems and social contexts; such research should include providing contraception, including long-acting contraception, in the context of less frequent clinical and ART refill visits.

Frequency of visits to health facilities and HIV services offered to men, Malawi

Objective

To determine how often men in Malawi attend health facilities and if testing for human immunodeficiency virus (HIV) is offered during facility visits.

Methods

We conducted a cross-sectional, community-representative survey of men (15–64 years) from 36 villages in Malawi. We excluded men who ever tested HIV-positive. Primary outcomes were: health facility visits in the past 12 months (for their own health (client visit) or to support the health services of others (guardian visit)); being offered HIV testing during facility visits; and being tested that same day. We disaggregated all results by HIV testing history: tested ≤ 12 months ago, or in need of testing (never tested or tested > 12 months before).

Findings

We included 1116 men in the analysis. Mean age was 34 years (standard deviation: 13.2) and 55% (617/1116) of men needed HIV testing. Regarding facility visits, 82% (920/1116) of all men and 70% (429/617) of men in need of testing made at least one facility visit in the past 12 months. Men made a total of 1973 visits (mean two visits): 39% (765/1973) were as guardians and 84% (1657/1973) were to outpatient departments. Among men needing HIV testing, only 7% (30/429) were offered testing during any visit. The most common reason for not testing was not being offered services (37%; 179/487).

Conclusion

Men in Malawi attend health facilities regularly, but few of those in need of HIV testing are offered testing services. Health screening services should capitalize on men’s routine visits to outpatient departments as clients and guardians.

Clinic-based diabetes screening at the time of HIV testing and associations with poor clinical outcomes in South Africa: a cohort study

BACKGROUND

HIV clinical care programs in high burden settings are uniquely positioned to facilitate diabetes diagnosis, which is a major challenge. However, in sub-Saharan Africa, data on the burden of diabetes among people living with HIV (PLHIV) and its impact on HIV outcomes is sparse.

METHODS

We enrolled adults presenting for HIV testing at an outpatient clinic in Durban. Those who tested positive for HIV-infection were screened for diabetes using a point-of-care hemoglobin A1c (HbA1c) test. We used log-binomial, Poisson, and Cox proportional hazard models adjusting for confounders to estimate the relationship of diabetes (HbA1c ≥ 6.5%) with the outcomes of HIV viral suppression (< 50 copies/mL) 4-8 months after antiretroviral therapy initiation, retention in care, hospitalization, tuberculosis, and death over 12 months.

RESULTS

Among 1369 PLHIV, 0.5% (n = 7) reported a prior diabetes diagnosis, 20.6% (95% CI 18.5-22.8%, n = 282) screened positive for pre-diabetes (HbA1c 5.7-6.4%) and 3.5% (95% CI 2.7-4.6%, n = 48) for diabetes. The number needed to screen to identify one new PLHIV with diabetes was 46.5 persons overall and 36.5 restricting to those with BMI ≥ 25 kg/m2. Compared to PLHIV without diabetes, the risk of study outcomes among those with diabetes was not statistically significant, although the adjusted hazard of death was 1.79 (95% CI 0.41-7.87).

CONCLUSIONS

Diabetes and pre-diabetes were common among adults testing positive for HIV and associated with death. Clinic-based diabetes screening could be targeted to higher risk groups and may improve HIV treatment outcomes.

Diabetes comorbidities in low- and middle-income countries: An umbrella review

Background

Diabetes mellitus, particularly type 2 diabetes, is a major public health burden globally. Diabetes is known to be associated with several comorbidities in high-income countries. However, our understanding of these associations in low- and middle-income countries (LMICs), where the epidemiological transition is leading to a growing dual burden of non-communicable and communicable disease, is less clear. We therefore conducted an umbrella review to systematically identify, appraise and synthesise reviews reporting the association between diabetes and multiple key comorbidities in LMICs.

Methods

We searched Medline, Embase, Global Health, and Global Index Medicus from inception to 14 November 2020 for systematic reviews, with or without meta-analyses, of cohort, case-control or cross-sectional studies investigating the associations between diabetes and cardiovascular disease (CVD), chronic kidney disease (CKD), depression, dengue, pneumonia, and tuberculosis within LMICs. We sought reviews of studies focused on LMICs, but also included reviews with a mixture of high-income and at least two LMIC studies, extracting data from LMIC studies only. We conducted quality assessment of identified reviews using an adapted AMSTAR 2 checklist. Where appropriate, we re-ran meta-analyses to pool LMIC study estimates and conduct subgroup analyses.

Results

From 11 001 articles, we identified 14 systematic reviews on the association between diabetes and CVD, CKD, depression, or tuberculosis. We did not identify any eligible systematic reviews on diabetes and pneumonia or dengue. We included 269 studies from 29 LMICs representing over 3 943 083 participants. Diabetes was positively associated with all comorbidities, with tuberculosis having the most robust evidence (16 of 26 cohort studies identified in total) and depression being the most studied (186 of 269 studies). The majority (81%) of studies included were cross-sectional. Heterogeneity was substantial for almost all secondary meta-analyses conducted, and there were too few studies for many subgroup analyses.

Conclusions

Diabetes has been shown to be associated with several comorbidities in LMICs, but the nature of the associations is uncertain because of the large proportion of cross-sectional study designs. This demonstrates the need to conduct further primary research in LMICs, to improve, and address current gaps in, our understanding of diabetes comorbidities and complications in LMICs.

ffects of integrated models of care for diabetes and hypertension in low-income and middle-income countries: a systematic review and meta-analysis

OBJECTIVES

To assess the effects of integrated models of care for people with multimorbidity including at least diabetes or hypertension in low-income and middle-income countries (LMICs) on health and process outcomes.

DESIGN

Systematic review.

DATA SOURCES

We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, LILACS, Africa-Wide, CINAHL and Web of Science up to 12 December 2019.

ELIGIBILITY CRITERIA

We included randomised controlled trials (RCTs), non-RCTs, controlled before-and-after studies and interrupted time series (ITS) studies of people with diabetes and/or hypertension plus any other disease, in LMICs; assessing the effects of integrated care.

DATA EXTRACTION AND SYNTHESIS

Two authors independently screened retrieved records; extracted data and assessed risk of bias. We conducted meta-analysis where possible and assessed certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

Of 7568 records, we included five studies-two ITS studies and three cluster RCTs. Studies were conducted in South Africa (n=3), Uganda/Kenya (n=1) and India (n=1). Integrated models of care compared with usual care may make little or no difference to mortality (very low certainty), the number of people achieving blood pressure (BP) or diabetes control (very low certainty) and access to care (very low certainty); may increase the number of people who achieve both HIV and BP/diabetes control (very low certainty); and may have a very small effect on achieving HIV control (very low certainty). Interventions to promote integrated delivery of care compared with usual care may make little or no difference to mortality (very low certainty), depression (very low certainty) and quality of life (very low certainty); and may have little or no effect on glycated haemoglobin (low certainty), systolic BP (low certainty) and total cholesterol levels (low certainty).

CONCLUSIONS

Current evidence on the effects of integrated care on health outcomes is very uncertain. Programmes and policies on integrated care must consider context-specific factors related to health systems and populations.
