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.

BACKGROUND
Prevalence of hypertension in Africa is rising but it remains underdiagnosed and poorly controlled. In Kenya, only 22% of individuals known to have hypertension were on treatment, and only 51.7% were controlled. This study will assess screening outcomes, retention and blood pressure (BP) control of a hypertension programme in Kenya.
DESIGN
This was a retrospective cohort study using data routinely collected between 2015 and 2018. All patients aged >18 years screened and treated in the programme were included.
RESULTS
Of 663,028 screening encounters, 70.4% were female; the median age was 34 years. Overall, 19% of the study population, mainly males and older persons, had high BP higher rates. Of 66,981 patients started on treatment, the majority were females (71.2%); the median age was 55 years. Only 12% of patients were reported as having been retained after 12 months, and 48.6% of patients on treatment 10.5-13.5 months after enrolment had controlled BP. Older age and treatment at primary care level were associated with better retention and females had better BP control.
CONCLUSIONS
The programme screened primarily females and younger individuals at lower risk. Retention was poor and close to half of patients retained had controlled BP. Hypertension programmes should target high-risk individuals, decentralise treatment, incorporate retention strategies and improve longitudinal data management.

OBJECTIVE
To determine and compare, among three models of care, compliance with scheduled clinic appointments and adherence to antihypertensive medication of patients in an informal settlement of Kibera, Kenya.
METHODS
Routinely collected patient data were used from three health facilities, six walkway clinics and one weekend/church clinic. Patients were eligible if they had received hypertension care for more than 6 months. Compliance with clinic appointments and self-reported adherence to medication were determined from clinic records and compared using the chi-square test. Univariate and multivariate logistic regression models estimated the odds of overall adherence to medication.
RESULTS
A total of 785 patients received hypertension treatment eligible for analysis, of whom two-thirds were women. Between them, there were 5879 clinic visits with an overall compliance with appointments of 63%. Compliance was high in the health facilities and walkway clinics, but men were more likely to attend the weekend/church clinics. Self-reported adherence to medication by those complying with scheduled clinic visits was 94%. Patients in the walkway clinics were two times more likely to adhere to antihypertensive medication than patients at the health facility (OR 1.97, 95% CI 1.25-3.10).
CONCLUSION
Walkway clinics outperformed health facilities and weekend clinics. The use of multiple sites for the management of hypertensive patients led to good compliance with scheduled clinic visits and very good self-reported adherence to medication in a low-resource setting.

Hypertension is the most important risk factor for cardiovascular diseases (CVDs), which are the leading global cause of death. Hypertension is under-diagnosed and under-treated in most low- and middle-income countries (LMICs). Current algorithms for hypertension treatment are complex for the healthcare worker, limit decentralization, complicate procurement and often translate to a large pill burden for the person with hypertension. We summarize evidence supporting implementation of simple, algorithmic, accessible, non-toxic and effective (SAANE) algorithms to provide a feasible way to access and maintain quality care for hypertension. Implementation of these algorithms will enable task shifting to less specialised health care workers and lay cadres, provision of fixed dose combinations, consolidation of the market while retaining generic competition, simplification of laboratory requirements, and lowering costs for health systems and people who incur out of pocket expenses.

PROBLEM
In Cambodia, care for people with HIV/AIDS (prevalence 1.9%) is expanding, but care for people with type II diabetes (prevalence 5-10%), arterial hypertension and other treatable chronic diseases remains very limited.
APPROACH
We describe the experience and outcomes of offering integrated care for HIV/AIDS, diabetes and hypertension within the setting of chronic disease clinics.
LOCAL SETTING
Chronic disease clinics were set up in the provincial referral hospitals of Siem Reap and Takeo, 2 provincial capitals in Cambodia.
RELEVANT CHANGES
At 24 months of care, 87.7% of all HIV/AIDS patients were alive and in active follow-up. For diabetes patients, this proportion was 71%. Of the HIV/AIDS patients, 9.3% had died and 3% were lost to follow-up, while for diabetes this included 3 (0.1%) deaths and 28.9% lost to follow-up. Of all diabetes patients who stayed more than 3 months in the cohort, 90% were still in follow-up at 24 months.
LESSONS LEARNED
Over the first three years, the chronic disease clinics have demonstrated the feasibility of integrating care for HIV/AIDS with non-communicable chronic diseases in Cambodia. Adherence support strategies proved to be complementary, resulting in good outcomes. Services were well accepted by patients, and this has had a positive effect on HIV/AIDS-related stigma. This experience shows how care for HIV/AIDS patients can act as an impetus to tackle other common chronic diseases.

BACKGROUND
Tackling the high non-communicable disease (NCD) burden among Syrian refugees poses a challenge to humanitarian actors and host countries. Current response priorities are the identification and integration of key interventions for NCD care into humanitarian programs as well as sustainable financing. To provide evidence for effective NCD intervention planning, we conducted a cross-sectional survey among non-camp Syrian refugees in northern Jordan to investigate the burden and determinants for high NCDs prevalence and NCD multi-morbidities and assess the access to NCD care.
METHODS
We used a two-stage cluster design with 329 randomly selected clusters and eight households identified through snowball sampling. Consenting households were interviewed about self-reported NCDs, NCD service utilization, and barriers to care. We estimated the adult prevalence of hypertension, diabetes type I/II, cardiovascular- and chronic respiratory conditions, thyroid disease and cancer and analysed the pattern of NCD multi-morbidities. We used the Cox proportional hazard model to calculate the prevalence ratios (PR) to analyse determinants for NCD prevalence and logistic regression to determine risk factors for NCD multi-morbidities by calculating odds ratios (ORs).
RESULTS
Among 8041 adults, 21.8%, (95% CI: 20.9-22.8) suffered from at least one NCD; hypertension (14.0, 95% CI: 13.2-14.8) and diabetes (9.2, 95% CI: 8.5-9.9) were the most prevalent NCDs. NCD multi-morbidities were reported by 44.7% (95% CI: 42.4-47.0) of patients. Higher age was associated with higher NCD prevalence and the risk for NCD-multi-morbidities; education was inversely associated. Of those patients who needed NCD care, 23.0% (95% CI: 20.5-25.6) did not seek it; 61.5% (95% CI: 54.7-67.9) cited provider cost as the main barrier. An NCD medication interruption was reported by 23.1% (95% CI: 20-4-26.1) of patients with regular medication needs; predominant reason was unaffordability (63.4, 95% CI: 56.7-69.6).
CONCLUSION
The burden of NCDs and multi-morbidities is high among Syrian refugees in northern Jordan. Elderly and those with a lower education are key target groups for NCD prevention and care, which informs NCD service planning and developing patient-centred approaches. Important unmet needs for NCD care exist; removing the main barriers to care could include cost-reduction for medications through humanitarian pricing models. Nevertheless, it is still essential that international donors agencies and countries fulfill their commitment to support the Syrian-crisis response.

Setting:
Three district hospitals (DHs) and seven health centers (HCs) in rural Rwanda.
Objective:
To describe follow-up and treatment outcomes in stage 1 and 2 hypertension patients receiving care at HCs closer to home in comparison to patients receiving care at DHs further from home.
Design:
A retrospective descriptive cohort study using routinely collected data involving adult patients aged ⩾18 years in care at chronic non-communicable disease clinics and receiving treatment for hypertension at DH and HC between 1 January 2013 and 30 June 2014.
Results:
Of 162 patients included in the analysis, 36.4% were from HCs. Patients at DHs travelled significantly further to receive care (10.4 km vs. 2.9 km for HCs, P < 0.01). Odds of being retained were significantly lower among DH patients when not adjusting for distance (OR 0.11, P = 0.01). The retention effect was consistent but no longer significant when adjusting for distance (OR 0.18, P = 0.10). For those retained, there was no significant difference in achieving blood pressure targets between the DHs and HCs.
Conclusion:
By removing the distance barrier, decentralizing hypertension management to HCs may improve long-term patient retention and could provide similar hypertension outcomes as DHs.

During June 2014 to April 2017, the population of Mosul, Iraq lived in a state of increasing isolation from the rest of Iraq due to the city's occupation by the Islamic State group. As part of a study to develop a generalisable method for estimating the excess burden of non-communicable diseases (NCDs) in conflict-affected settings, in April-May 2017 we conducted a brief qualitative study of self-reported care for NCDs among 15 adult patients who had fled Mosul and presented to Médecins Sans Frontières clinics in the Kurdistan region with hypertension and/or diabetes. Participants reported consistent barriers to NCD care during the so-called Islamic State period, including drug shortages, insecurity and inability to afford privately sold medication. Coping strategies included drug rationing. By 2016, all patients had completely or partially lost access to care. Though limited, this study suggests a profound effect of the conflict on NCD burden.

INTRODUCTION
Low adherence to medications, specifically in patients with Diabetes (DM) and Hypertension (HTN), and more so in refugee settings, remains a major challenge to achieving optimum clinical control in these patients. We aimed at determining the self-reported medication adherence prevalence and its predictors and exploring reasons for low adherence among these patients.
METHODS
A mixed-methods study was conducted at Médecins Sans Frontières non-communicable diseases primary care center in the Shatila refugee camp in Beirut, Lebanon in October 2018. Data were collected using the validated Arabic version of the 8-items Morisky Medication Adherence Scale (MMAS-8) concurrently followed by in-depth interviews to explore barriers to adherence in patients with DM and/or HTN. Predictors of adherence were separately assessed using logistic regression with SPSS© version 20. Manual thematic content analysis was used to analyze the qualitative data.
RESULTS
Of the 361 patients included completing the MMAS, 70% (n = 251) were moderately to highly adherent (MMAS-8 score = 6 to 8), while 30% (n = 110) were low-adherent (MMAS-8 score<6). Patients with DM-1 were the most likely to be moderately to highly adherent (85%; n = 29). Logistic regression analysis showed that patients with a lower HbA1C were 75% more likely to be moderately to highly adherent [(OR = 0.75 (95%CI 0.63-0.89), p-value 0.001]. Factors influencing self-reported moderate and high adherence were related to the burden of the disease and its treatment, specifically insulin, the self-perception of the disease outcomes and the level of patient's knowledge about the disease and other factors like supportive family and healthcare team.
CONCLUSION
Adherence to DM and HTN was good, likely due to a patient-centered approach along with educational interventions. Future studies identifying additional factors and means addressing the barriers to adherence specific to the refugee population are needed to allow reaching optimal levels of adherence and design well-informed intervention programs.
