BACKGROUND
In 2024, the World Health Organization released a report on Priorities for Research on Hypertension Care Delivery. This article provides its executive summary.
METHODS
The World Health Organization and its technical experts formed a leadership team, developed a scope and objectives, created a thematic framework, developed a survey for each theme, and identified research priorities. The 5 themes included (1) Health care workforce for hypertension care delivery, (2) Service delivery system/models, (3) Patient retention/adherence, (4) Financing the care delivery system, and (5) Research gaps identified in the World Health Organization 2021 Hypertension Guideline. The leadership team received feedback from diverse experts through webinars and online surveys. The final report was peer-reviewed by external experts.
RESULTS
According to postwebinar surveys, we identified 5 to 7 research priorities within each theme, totaling 29 research priorities. The 10 highest priorities were (1) Cost-effectiveness of combination therapy in low/middle-income countries, (2) A system allowing hypertension care closer to home, (3) Health system reform allowing trained community health workers to refill/initiate/titrate antihypertensive medications, (4) Health system reform allowing nurses to diagnose and treat hypertension, (5) Gaps in the medication supply chain, (6) New approaches integrating the management of hypertension and other diseases, (7) Digital approaches for improving medication adherence, (8) Optimal approaches to train health care workers, (9) Approaches to finance hypertension control programs, and (10) Implementation research on task-sharing approaches.
CONCLUSIONS
These research priorities provide guidance to researchers, with immediate implications for substantially improve hypertension care and prevent its sequelae. We urge governments, funding agencies, and organizations to consider supporting these research topics.

IMPORTANCE
The burden of diabetes is growing worldwide. The costs associated with diabetes put substantial pressure on patients and health budgets, especially in low- and middle-income countries. The prices of diabetes medicines are a key determinant for access, yet little is known about the association between manufacturing costs and current market prices.
OBJECTIVES
To estimate the cost of manufacturing insulins, sodium-glucose cotransporter 2 inhibitors (SGLT2Is), and glucagonlike peptide 1 agonists (GLP1As), derive sustainable cost-based prices (CBPs), and compare these with current market prices.
DESIGN, SETTING, AND PARTICIPANTS
In this economic evaluation, the cost of manufacturing insulins, SGLT2Is, and GLP1As was modeled. Active pharmaceutical ingredient cost per unit (weighted least-squares regression model using data from a commercial database of trade shipments, data from January 1, 2016, to March 31, 2023) was combined with costs of formulation and other operating expenses, plus a profit margin with an allowance for tax, to estimate CBPs. Cost-based prices were compared with current prices in 13 countries, collected in January 2023 from public databases. Countries were selected to provide representation of different income levels and geographic regions based on the availability of public databases.
MAIN OUTCOMES AND MEASURES
Estimated CBPs; lowest current market prices (2023 US dollars).
RESULTS
In this economic evaluation of manufacturing costs, estimated CBPs for treatment with insulin in a reusable pen device could be as low as $96 (human insulin) or $111 (insulin analogues) per year for a basal-bolus regimen, $61 per year using twice-daily injections of mixed human insulin, and $50 (human insulin) or $72 (insulin analogues) per year for a once-daily basal insulin injection (for type 2 diabetes), including the cost of injection devices and needles. Cost-based prices ranged from $1.30 to $3.45 per month for SGLT2Is (except canagliflozin: $25.00-$46.79) and from $0.75 to $72.49 per month for GLP1As. These CBPs were substantially lower than current prices in the 13 countries surveyed.
CONCLUSIONS AND RELEVANCE
High prices limit access to newer diabetes medicines in many countries. The findings of this study suggest that robust generic and biosimilar competition could reduce prices to more affordable levels and enable expansion of diabetes treatment globally.

: A multicentric, retrospective case-series analysis (facility-based) in five sites across Kenya, Malawi, Mozambique, and Uganda screened HIV-positive adults for hepatitis C virus (HCV) antibodies using Oraquick rapid testing and viral confirmation (in three sites). Results found substantially lower prevalence than previously reported for these countries compared with previous reports, suggesting that targeted integration of HCV screening in African HIV programs may be more impactful than routine screening.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Introduction: Counselling services are recommended by the World Health Organization and have been partially adopted by national HIV guidelines. In settings with a high HIV burden, patient education and counselling is often performed by lay workers, mainly supported with international funding. There are few examples where ministries of health have been able to absorb lay counsellors into their health systems or otherwise sustain their work. We document the role of lay cadres involved in HIV testing and counselling and adherence support and discuss approaches to sustainability. Methods: We focused on a purposive sample of eight sub-Saharan African countries where Médecins Sans Frontières supports HIV programmes: Guinea, Lesotho, Malawi, Mozambique, South Africa, Swaziland, Zambia and Zimbabwe. We reviewed both published and grey literature, including national policies and donor proposals, and interviewed key informants, including relevant government staff, donors and non-governmental organizations. Results and discussion: Lay counsellors play a critical role in scaling up HIV services and addressing gaps in the HIV testing and treatment cascade by providing HIV testing and counselling and adherence support at both the facility and community levels. Countries have taken various steps in recognizing lay counsellors, including harmonizing training, job descriptions and support structures. However, formal integration of this cadre into national health systems is limited, as lay counsellors are usually not included in national strategies or budgeting. Conclusions: The current trend of reduced donor support for lay counsellors, combined with lack of national prioritization, threatens the sustainability of this cadre and thereby quality HIV service delivery.

INTRODUCTION
The number of people on antiretroviral therapy (ART) for the long-term management of HIV in low- and middle-income countries (LMICs) is continuing to increase, along with the prevalence of Non-Communicable Diseases (NCDs). The need to provide large volumes of HIV patients with ART has led to significant adaptations in how medication is delivered, but access to NCD care remains limited in many contexts. Medication Adherence Clubs (MACs) were established in Kibera, Kenya to address the large numbers of patients requiring chronic HIV and/or NCD care. Stable NCD and HIV patients can now collect their chronic medication every three months through a club, rather than through individual clinic appointments.
METHODOLOGY
We conducted a qualitative research study to assess patient and health-care worker perceptions and experiences of MACs in the urban informal settlement of Kibera, Kenya. A total of 106 patients (with HIV and/or other NCDs) and health-care workers were purposively sampled and included in the study. Ten focus groups and 19 in-depth interviews were conducted and 15 sessions of participant observation were carried out at the clinic where the MACs took place. Thematic data analysis was conducted using NVivo software, and coding focussed on people’s experiences of MACs, the challenges they faced and their perceptions about models of care for chronic conditions.
RESULTS
MACs were considered acceptable to patients and health-care workers because they saved time, prevented unnecessary queues in the clinic and provided people with health education and group support whilst they collected their medication. Some patients and health-care workers felt that MACs reduced stigma for HIV positive patients by treating HIV as any other chronic condition. Staff and patients reported challenges recruiting patients into MACs, including patients not fully understanding the eligibility criteria for the clubs. There were also some practical challenges during the implementation of the clubs, but MACs have shown that it is possible to learn from ART provision and enable stable HIV and NCD patients to collect chronic medication together in a group.
CONCLUSIONS
Extending models of care previously only offered to HIV-positive cohorts to NCD patients can help to de-stigmatise HIV, allow for the efficient clinical management of co-morbidities and enable patients to benefit from peer support. Through MACs, we have demonstrated that an integrated approach to providing medication for chronic diseases including HIV can be implemented in resource-poor settings and could thus be rolled out in other similar contexts.

INTRODUCTION
Globally, hypertension is responsible for approximately half of all heart disease and stroke deaths. Over 75% of these deaths occur in low- and middle-income countries. However globally, hypertension awareness, treatment, and control remain low (39%, 29%, and 10%, respectively). Reasons for poor control are multifactorial, and include patient-specific factors such as poor adherence, often associated with high pill-burden regimens. Health system factors are also important and may include the use of complex algorithms, leading to clinical inertia amongst healthcare workers. Fixed-dose combination (FDC) medications may be one way of reducing pill burden and simplifying clinical algorithms. To understand the use of multiple drug classes in the management of hypertension we analysed antihypertensive prescribing patterns and blood pressure (BP) control in cohorts from MSF treatment programmes in Jordan and Zimbabwe to determine the proportion of patients who may benefit from a FDC (those currently treated with more than two drug classes) and the potential extent of clinical inertia.
METHODS
We used routine, retrospective data from two cohorts of adult patients with hypertension; one from Jordan, a semi-urban clinic managed by doctors (using data from October 2016 to December 2018) and one from Zimbabwe, a rural setting managed by nurses (data from May 2016 to July 2019). We carried out descriptive analyses of prescribing patterns and their relationship with BP control.
Ethics
This study was approved by the ethics committees of Jordan and Zimbabwe and the MSF Ethics Review Board.
RESULTS
We analysed data from 3305 and 3957 hypertensive patients from Jordan and Zimbabwe respectively; with median ages in Jordan 61 (interquartile range, IQR, 53-69) and in Zimbabwe 63 (IQR 53-70); the majority were female (62.7% and 80.4% respectively). Retention and BP control at 12 months were 95% and 77% (Jordan) and 59% and 42.3% (Zimbabwe). The proportion of patients on two, three, or four-five antihypertensive drug classes at baseline were 42%, 19%, 4% in Jordan and 46%, 7%, <1% in Zimbabwe. At 12 months follow-up, proportions were 40%, 28%, 11% in Jordan and 46%, 17%, 1% in Zimbabwe. Proportions with controlled BP at 12 months on two, three, or four-five drug classes were 71%, 64% and 55% in Jordan, and 40%, 27%, 25% in Zimbabwe. No medication change for uncontrolled BP was made at the next visit for 1,843 (79.3%) of 2,325 visits in Jordan, and 4,763 (63.5%) of 7,497 visits in Zimbabwe. This included 545 (28.6%) and 2,549 (53.5%) visits with uncontrolled stage two or three hypertension respectively.
CONCLUSION
Most patients with hypertension required more than two antihypertensive medications, but a significant proportion persisted with uncontrolled BP. No additional class of antihypertensive was given in the majority of visits by patients with uncontrolled BP, suggesting possible clinical inertia by healthcare workers. Despite recent inclusion of FDC’s in MSF guidelines and WHO’s Essential Medicines List, their lack of inclusion in national guidelines, and procurement challenges, have hindered MSF’s implementation of FDC’s. Demonstrating feasibility of FDC use in MSF pilot projects could play an important role in furthering uptake.
