Estimated health benefits, costs and cost-effectiveness of eliminating industrial trans-fatty acids in Nigeria: cost-effectiveness analysis.

INTRODUCTION: Nigeria is committed to reducing industrial trans-fatty acids (iTFA) from the food supply, but the potential health gains, costs and cost-effectiveness are unknown. METHODS: The effect on ischaemic heart disease (IHD) burden, costs and cost-effectiveness of a mandatory iTFA limit (≤2% of all fats) for foods in Nigeria were estimated using Markov cohort models. Data on demographics, IHD epidemiology and trans-fatty acid intake were derived from the 2019 Global Burden of Disease Study. Avoided IHD events and deaths; health-adjusted life years (HALYs) gained; and healthcare, policy implementation and net costs were estimated over 10 years and the population's lifetime. Incremental cost-effectiveness ratios using net costs and HALYs gained (both discounted at 3%) were used to assess cost-effectiveness. RESULTS: Over the first 10 years, a mandatory iTFA limit (assumed to eliminate iTFA intake) was estimated to prevent 9996 (95% uncertainty interval: 8870 to 11 118) IHD deaths and 66 569 (58 862 to 74 083) IHD events, and to save US$90 million (78 to 102) in healthcare costs. The corresponding lifetime estimates were 259 934 (228 736 to 290 191), 479 308 (95% UI 420 472 to 538 177) and 518 (450 to 587). Policy implementation costs were estimated at US$17 million (11 to 23) over the first 10 years, and US$26 million USD (19 to 33) over the population's lifetime. The intervention was estimated to be cost-saving, and findings were robust across several deterministic sensitivity analyses. CONCLUSION: Our findings support mandating a limit of iTFAs as a cost-saving strategy to reduce the IHD burden in Nigeria.

Evaluation of Primary Healthcare Centers' Service Availability and Readiness for Implementing Diabetes Care in Abuja, Nigeria: A Cross-Sectional, Formative Assessment.

Introduction: Noncommunicable diseases (NCDs) are associated with a high and rising burden of morbidity and mortality in sub-Saharan Africa, including Nigeria. Diabetes mellitus (DM) is among the leading causes of NCD-related deaths worldwide and is a foremost public health problem in Nigeria. As part of the National Multi-Sectoral Action Plan for the Prevention and Control of NCDs, Nigeria has committed to implementing the World Health Organization (WHO) Package of Essential NCD control interventions. Implementing the intervention requires the availability of essential elements, including guidelines, trained staff, health management information systems, equipment, and medications, in primary healthcare centers (PHCs). This study assessed the availability of the WHO package components and the readiness of PHCs to implement a DM screening, evaluation, and management program. Methods: This cross-sectional formative assessment adapted the WHO Service Availability and Readiness Assessment (SARA) tool to survey 30 PHCs selected by multistage sampling for readiness to deliver DM diagnosis and care in Abuja, Nigeria, between August 2021 and October 2021. The service availability and readiness indicator scores were calculated based on the proportion of PHCs with available DM care services, minimum staff requirement, diagnostic tests, equipment, medications, and national guidelines/protocols for DM care within the defined SARA domain. Results: All 30 PHCs reported the availability of at least two full-time staff (median [interquartile range] staff = 5 [4-9]), which were mostly community health extension workers (median [interquartile range]) = 3 [1-4]. At least one staff member was recently trained in DM care in only 11 (36%) of the PHCs. The study also reported high availability (100%) of paper-based health management information systems (HMIS) and DM screening services using a glucometer (87%), but low availability of DM treatment (23%), printed job aids (27%), and national guidelines/protocols (0%). Conclusion: This systematic assessment of PHCs' readiness to implement a DM screening, evaluation, and management program in Abuja demonstrated readiness to integrate DM care into PHCs in terms of equipment, paper-based HMIS, and nonphysician health workers' availability. However, strategies are needed to promote DM health workforce training, provide DM management guidelines, and ensure a reliable supply of essential DM medications.

On-demand mobile hypertension training for primary health care workers in Nigeria: a pilot study.

BACKGROUND: Only one out of every ten Nigerian adults with hypertension has their blood pressure controlled. Health worker training is essential to improve hypertension diagnosis and treatment. In-person training has limitations that mobile, on-demand training might address. This pilot study evaluated a self-paced, case-based, mobile-optimized online training to diagnose and manage hypertension for Nigerian health workers. METHODS: Twelve hypertension training modules were developed, based on World Health Organization and Nigerian guidelines. After review by local academic and government partners, the course was piloted by Nigerian health workers at government-owned primary health centers. Primary care physician, nurse, and community health worker participants completed the course on their own smartphones. Before and after the course, hypertension knowledge was evaluated with multiple-choice questions. Learners provided feedback by responding to questions on a Likert scale. RESULTS: Out of 748 users who sampled the course, 574 enrolled, of whom 431 (75%) completed the course. The average pre-test score of completers was 65.4%, which increased to 78.2% on the post-test (P < 0.001, paired t-test). Health workers who were not part of existing hypertension control programs had lower pre-test scores and larger score gains. Most participants (96.1%) agreed that the training was applicable to their work, and nearly all (99.8%) agreed that they enjoyed the training. CONCLUSIONS: An on-demand mobile digital hypertension training increases knowledge of hypertension management among Nigerian health workers. If offered at scale, such courses can be a tool to build health workforce capacity through initial and refresher training on current clinical guidelines in hypertension and other chronic diseases in Nigeria as well as other countries.

Moving forward: Scaling-up the integration of an HIV and hypertension program in Akwa Ibom State, Nigeria.

Background: As people living with HIV experience increased life expectancy, there is a growing concern about the burden of comorbid non-communicable diseases, particularly hypertension. This policy brief describes the current policy landscape in Akwa Ibom State, Nigeria, the research activities, and five policy recommendations rooted in an ongoing research study designed to integrate hypertension management into HIV care across primary health centers in the state. Analysis: The policy brief was developed in four steps: review of existing policies, using the reviewed policies to inform research activities, solicitation of stakeholder recommendations via focus group discussions, and formulation of the resulting five policy recommendations for integrating hypertension management into HIV care programs in Akwa Ibom. The key analysis for this brief emerged from the thematic analyses of stakeholder responses. Policy Implications: The five policy recommendations for integrating hypertension management in HIV care in Akwa Ibom State, Nigeria are: 1) build capacity by leveraging retired community nurses as mentors; 2) emphasize community engagement; 3) develop consistent training programs on hypertension management for health workers; 4) expand health insurance accessibility; and 5) formally integrate hypertension management into primary healthcare centers in Akwa Ibom State.

Interventions and contextual factors to improve retention in care for patients with hypertension in primary care: Hermeneutic systematic review.

BACKGROUND: Regular engagement over time in hypertension care, or retention, is a crucial but understudied step in optimizing patient outcomes. This systematic review leverages a hermeneutic methodology to identify, evaluate, and quantify the effects of interventions and contextual factors for improving retention for patients with hypertension. METHODS: We searched for articles that were published between 2000 and 2022 from multiple electronic databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and WHO International Trials Registry. We followed the latest version of the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline to report the findings for this review. We also synthesized the findings using a hermeneutic methodology for systematic reviews, which used an iterative process to review, integrate, analyze, and interpret evidence. RESULTS: From 4686 screened titles and abstracts, 18 unique studies from 9 countries were identified, including 10 (56%) randomized controlled trials (RCTs), 3 (17%) cluster RCTs, and 5 (28%) non-RCT studies. The number of participants ranged from 76 to 1562. The overall mean age range was 41-67 years, and the proportion of female participants ranged from 0% to 100%. Most (n = 17, 94%) studies used non-physician personnel to implement the proposed interventions. Fourteen studies (78%) implemented multilevel combinations of interventions. Education and training, team-based care, consultation, and Short Message Service reminders were the most common interventions tested. CONCLUSIONS: This review presents the most comprehensive findings on retention in hypertension care to date and fills the gaps in the literature, including the effectiveness of interventions, their components, and contextual factors. Adaptation of and implementing HIV care models, such differentiated service delivery, may be more effective and merit further study. REGISTRATION: CRD42021291368.

ACHIEVE conference proceedings: implementing action plans to reduce and control hypertension burden in Africa.

The prevalence of hypertension, the commonest risk factor for preventable disability and premature deaths, is rapidly increasing in Africa. The African Control of Hypertension through Innovative Epidemiology, and a Vibrant Ecosystem [ACHIEVE] conference was convened to discuss and initiate the co-implementation of the strategic solutions to tame this burden toward achieving a target of 80% for awareness, treatment, and control by the year 2030. Experts, including the academia, policymakers, patients, the WHO, and representatives of various hypertension and cardiology societies generated a 12-item communique for implementation by the stakeholders of the ACHIEVE ecosystem at the continental, national, sub-national, and local (primary) healthcare levels.

Rationale for a New Low-Dose Triple Single Pill Combination for the Treatment of Hypertension.

Two recent large trials showed the potential of single pill combinations (SPCs) with ≥3 low-dose components among people with hypertension who were untreated or receiving monotherapy. In both trials, these 'hypertension polypills' were superior to usual care, achieving >80% BP control without increasing withdrawal due to side effects. However, there are no such products available for prescribers. To address this unmet need, George Medicines developed GMRx2 with telmisartan/amlodipine/indapamide in three strengths (mg): 10/1.25/0.625, 20/2.5/1.25; 40/5/2.5. Two pivotal trials are ongoing to support FDA submission for the treatment of hypertension, including initial treatment. These assess efficacy and safety of GMRx2 compared to: placebo, and each of the three possible dual combinations. Regulatory submissions are planned for 2024, with the aim of providing access to GMRx2 in developed and developing regions. Wider implementation of GMRx2-based treatment strategies will be guided by further research to inform access and appropriate scale up.

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.

Formative Evaluation and Adaptation of a Hypertension Extension for Community Health Outcomes Program for Healthcare Workers within the Federal Capital Territory, Nigeria.

Background: The Extension for Community Health Outcomes (ECHO) model has been used extensively to link care providers in rural communities with experts with the aim of improving local patient care. Objective: The aim of this qualitative research study was to assess the feasibility, acceptability, perceived needs, and contextual factors to guide implementation of a hypertension focused ECHO program for Community Health Extension Workers (CHEWs) in the Federal Capital Territory, Nigeria. Methods: From September 2020 to December 2020, key informant interviews were performed with seven global organizations (hubs) providing ECHO training focused on cardiovascular disease or nephrology to identify contextual factors and implementation strategies used by each hub. In February 2022, seven focus group discussions were performed with 42 frontline healthcare workers in the Federal Capital Territory to inform local adaptation of a hypertension ECHO program. Directed content analysis identified major themes which were mapped to the Consolidated Framework for Implementation Research. Qualitative analyses were performed using Dedoose, and results were synthesized using the Implementation Research Logic Model. Results: We found both barriers and facilitators across the Consolidated Framework for Implementation Research domains that mapped to a number of constructs in each one. The results of these analyses confirmed that the core components of the ECHO model are a feasible and appropriate intervention for hypertension education of healthcare workers. However, implementing the ECHO program within the Federal Capital Territory may require strategies such as utilizing communications resources effectively, developing incentives to motivate initial participation, and providing rewards or recognition for ongoing engagement. Conclusions: These results provide valuable formative insights to guide implementation of our proposed hypertension ECHO program for CHEWs in the Federal Capital Territory, Nigeria. This information was used for key decisions around: 1) scope and content of training, 2) format and frequency, 3) selection of implementation strategies, and 4) building a community of practice.

Facilitators and barriers to optimal home blood pressure management in patients with hypertensive disorders of pregnancy in a tertiary care facility in Abuja, Nigeria: a qualitative research study.

BACKGROUND: Nigeria has one of the highest burdens of maternal deaths globally, and hypertensive disorders of pregnancy (HDP) are the leading cause of maternal morbidity and mortality in the country. There is a significant implementation gap in utilizing evidence-based practices for the management of HDP in Nigeria. This study evaluated facilitators and barriers to implementing a home blood pressure monitoring program to improve management of HDP. METHODS: From August 2022 to September 2022, we conducted 15 semi-structured, key informant interviews and 4 focus group discussions among patients, health care workers, and administrators at University of Abuja Teaching Hospital (UATH), a tertiary care centre in Nigeria. The study used the Consolidated Framework for Implementation Research to assess five domains: individual characteristics, inner and outer settings, intervention characteristics, and process of implementation. Audio files were transcribed, and data were analysed using a combination of inductive and deductive approaches. We also conducted 32 brief surveys on the participants to assess acceptability, appropriateness, and feasibility of a blood pressure monitoring program. RESULTS: The study sample consisted of healthcare workers (n=22) including specialists in cardiology, obstetrics and gynaecology, maternal-foetal medicine, nurses/midwives and resident doctors as well as patients (n=10). Mean (SD) age was 39.5 (10.9), and 78% were female. Participants identified facilitators including the perceived simplicity of home blood pressure monitoring program, high burden of HDP, and availability of a multi-disciplinary team of healthcare professionals with expertise in HDP management. Barriers identified were cost, limited knowledge of HDP amongst patients, limited transportation networks, inconsistent management protocols, and inadequate manpower and facilities. Survey results indicated that between 81% and 88% of participants reported that a blood pressure monitoring program would be acceptable, 56%-72% reported that it would be appropriate, and 47%-69% reported that it would be feasible. CONCLUSION: This study identified facilitators and barriers while highlighting key implementation strategies to leverage and effectively address these respectively to enable successful implementation of a home blood pressure monitoring program. It also demonstrated that a home blood pressure monitoring program was considered acceptable, appropriate and feasible among respondents interviewed at UATH.

Comparative cardiac effects of antimalarial drug halofantrine with or without concomitant administration of kolanut or fluconazole in healthy volunteers.

Background: There is rekindled interest in the cardiotoxicity of antimalarial medicines. Halofantrine is associated with QT interval prolongation. Fluconazole and kolanut alter the pharmacokinetics of halofantrine. Objectives: The study assessed the electrocardiographic changes of concomitant administration of kolanut or fluconazole with halofantrine and the effects on the QTc interval. Methods: Eighteen healthy volunteers received a single oral dose of halofantrine, halofantrine with kolanut or halofantrine with fluconazole in a crossover study. Twelve lead electrocardiography (ECG) was performed to measure the PR and QT interval (QTc). Statistical analysis was with SPSS at 5% level of significance. Results: PR intervals were shortened by halofantrine alone and halofantrine with kolanut (169.29 28.67 to 165.29 28.007 and 172.73 29.843 to 163.00 18.336ms) but was prolonged by halofantrine with fluconazole (177.70 27.394 to 186.59 44.434ms). There was prolongation of QTc (384.76 21.727 to 394.12 21.525; 381.36 22.29 to 388.30 17.26 and 382.35 20.08 to 390.84 21.97) in all the three treatment groups at 6 hours, p>0.05. One subject on halofantrine and fluconazole had QTc >440ms. Pre-treatment PR interval (PR0) correlated well with post-treatment PR6, and with PR14 r= 0.519, p= 0.014; r=0.664, p=0.013. Conclusion: Concomitant intake of kolanut with halofantrine was significantly decrease cardiac effect of halofantrine.

The Pandemic of Coronary Artery Disease in the Sub-Saharan Africa: What Clinicians Need to Know.

PURPOSE OF REVIEW: Cardiovascular diseases (CVDs) are a leading cause of morbidity and mortality globally with an accelerated increase in CVD­related death in Africa and other low­middle­income countries. This review is aimed at highlighting the burden of coronary artery disease CAD, its peculiarities as well as challenges of management in sub-Saharan Africa. RECENT FINDINGS: Recent data revealed a shift from high incidence of CVDs associated with poverty and malnutrition (such as rheumatic heart disease) initially, which are now falling, to rising incidence of other non-communicable CVDs (such as hypertension, coronary artery disease (CAD), and heart failure). Africa disproportionately bears the brunt of CVD burden and has one of the highest risks of dying from non-communicable diseases (NCDs) worldwide, which is projected to supersede communicable diseases in the future. Previous studies have shown that CAD was rare among Africans. Those studies conducted in Africa in the 1940s-1960s reported that Black Africans were almost immune to developing CAD and were even thought to have specific genetic make-up protecting them from CAD. However, the continent is now experiencing a steady rise in the prevalence of CAD associated with severe disease burden, compared to other regions of the world. The changes seen have been attributed to the current epidemiological transition with increase in CVD risk factors that are poorly controlled, lack of awareness as well as the poor health facilities to tackle the menace of the disease. The Global Burden of Disease (GBD) estimates have also shown that over the past three decades the highest contribution to CVD burden in Africa is attributed to atherosclerotic diseases, with 71.4, 37.7, and 154% increases in the burden of ischemic heart disease, stroke, and peripheral artery disease respectively. There is a steady increase of CAD prevalence in Africa as a result of increase in CV risk factors. Hypertension, obesity, diabetes, dyslipidemia, and cigarette smoking are the rapidly rising risk factors for CAD on the continent. Africa also faces challenges in diagnosis and management of CAD. There is need for increased public and health personnel awareness on prevention and control of commonly identifiable risk factors, provision of prehospital emergency services, and provision of modern therapeutic facilities for treatment of CAD including reperfusion therapy. These are priority areas where efforts could be intensified in the future with potential to improve the current rate of progress of the disease on the continent.

Building Capacity of Community Nurses to Strengthen the Management of Uncomplicated Hypertension in Persons Living with HIV in Low- and Middle-Income Countries.

Objectives: Poor training of non-physician healthcare workers (especially community nurses) could hinder the successful integration of cardiovascular disease (CVD) management into HIV chronic care in primary healthcare facilities in low- and middle-income countries. To address this limitation, we included a holistic training programme with a robust module for both practice facilitators and community nurses as part of the formative stages of the managing hypertension among people living with HIV: an integrated model (MAP-IT), which is a study that is evaluating the effectiveness of practice facilitation on the integration of a task-strengthening strategy for hypertension control (TASSH) into primary healthcare centres in Akwa Ibom State of Nigeria. Methods: Between June and November 2021, 3 didactic training workshops were conducted using a training module which is based on the simplified Nigerian Hypertension Protocol for primary care and the World Health Organization (WHO) heart package. Knowledge acquired by the participants was assessed using anonymized pre- and post-training assessments in the first two workshops. Participants' view of the training was assessed using a comprehensive course evaluation questionnaire. Results: A total of 92 community nurses and six practice facilitators were trained in the workshops on managing hypertension in persons living with HIV. Mean pre- and post-test scores improved from 11.9(3.4) to 15.9(2.9); p < 0.001 in the first workshop, and from 15.4(0.9) to 16.4 (1.4); p < 0.001 in the second workshop. The methodology used in the training, understanding of the MAP-IT study programme, and the level of engagement was highly rated by the participants with LIKERT scores of 3.2/4.0, 3.2/4.0, and 3.1/4.0 respectively. Conclusion: Our training methodology, which involved the train-the-trainer model to deliver simplified HIV and HTN care guidelines, showed improvement in the knowledge of managing hypertension in persons living with HIV and was highly rated by participants.

Elevated blood pressure among adolescents in sub-Saharan Africa: a systematic review and meta-analysis.

BACKGROUND: More people from sub-Saharan Africa aged between 20 years and 60 years are affected by end-organ damage due to underlying hypertension than people in high-income countries. However, there is a paucity of data on the pattern of elevated blood pressure among adolescents aged 10-19 years in sub-Saharan Africa. We aimed to provide pooled estimates of high blood pressure prevalence and mean levels in adolescents aged 10-19 years across sub-Saharan Africa. METHODS: In this systematic review and meta-analysis, we searched PubMed, Google Scholar, African Index Medicus, and Embase to identify studies published from Jan 1, 2010, to Dec 31, 2021. To be included, primary studies had to be observational studies of adolescents aged 10-19 years residing in sub-Saharan African countries reporting the pooled prevalence of elevated blood pressure or with enough data to compute these estimates. We excluded studies on non-systemic hypertension, in African people not living in sub-Saharan Africa, with participant selection based on the presence of hypertension, and with adult cohorts in which we could not disaggregate data for adolescents. We independently extracted relevant data from individual studies using a standard data extraction form. We used a random-effects model to estimate the pooled prevalence of elevated blood pressure and mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels overall and on a sex-specific basis. This study is registered with PROSPERO (CRD42022297948). FINDINGS: We identified 2559 studies, and assessed 81 full-text studies for eligibility, of which 36 studies comprising 37 926 participants aged 10-19 years from ten (20%) of 49 sub-Saharan African countries were eligible. A pooled sample of 29 696 adolescents informed meta-analyses of elevated blood pressure and 27 155 adolescents informed meta-analyses of mean blood pressure. Sex data were available from 26 818 adolescents (14 369 [53·6%] were female and 12 449 [46·4%] were male) for the prevalence of elevated blood pressure and 23 777 adolescents (12 864 [54·1%] were female and 10 913 [45·9%] were male) for mean blood pressure. Study quality was high, with no low-quality studies. The reported prevalence of elevated blood pressure ranged from 4 (0·2%) of 1727 to 1755 (25·1%) of 6980 (pooled prevalence 9·9%, 95% CI 7·3-12·5; I?=99·2%, pheterogeneity<0·0001). Mean SBP was 111 mm Hg (95% CI 108-114) and mean DBP was 68 mm Hg (66-70). 13·4% (95% CI 12·9-13·9; pheterogeneity<0·0001) of male participants had elevated blood pressure compared with 11·9% (11·3-12·4; pheterogeneity<0·0001) of female participants (odds ratio 1·04, 95% CI 0·81-1·34; pheterogeneity<0·0001). INTERPRETATION: To our knowledge, this systematic review and meta-analysis is the first systematic synthesis of blood pressure data specifically derived from adolescents in sub-Saharan Africa. Although many low-income countries were not represented in our study, our findings suggest that approximately one in ten adolescents have elevated blood pressure across sub-Saharan Africa. Accordingly, there is an urgent need to improve preventive heart-health programmes in the region. FUNDING: None.

Landscape of team-based care to manage hypertension: results from two surveys in low/middle-income countries.

OBJECTIVES: Team-based care is essential for improving hypertension outcomes in low-resource settings. We assessed perceptions of country representatives and healthcare workers (HCWs) on team-based hypertension care in low/middle-income countries. DESIGN: Two cross-sectional surveys. SETTING: The first survey (Country Profile Survey) was conducted in 17 countries and eight in-country regions: Algeria, Bangladesh, Burundi, Chile, China (Beijing, Henan, Shandong), Cuba, Ethiopia, India (Kerala, Madhya Pradesh, Maharashtra, Punjab, Telangana), Nepal, Nigeria, Philippines, Saint Lucia, Sri Lanka, Thailand, Turkey, Uganda and Vietnam. The second survey (HCW Survey) was conducted in four countries: Bangladesh, China, Ethiopia and Nigeria. PARTICIPANTS: Using convenience sampling, participants for the Country Profile Survey were representatives from 17 countries and eight in-country regions, and the HCW Survey was administered to HCWs in Bangladesh, China, Ethiopia and Nigeria. OUTCOME MEASURES: Country-level use of team-based hypertension care framework, comprising administrative, basic and advanced clinical tasks. Current practices of different HCW cadres, perspectives on team-based management of hypertension, barriers and facilitators. RESULTS: In the Country Profile Survey, all (23/23, 100%) countries/regions surveyed integrated team-based care for basic clinical hypertension management tasks, less for advanced tasks (7/23, 30%). In the HCW Survey, 854 HCWs participated, 47% of whom worked in rural settings. Most HCWs in the sample acknowledged the value of team-based hypertension care. Although there were slight variations by country in the study sample, overall, barriers to team-based hypertension care were identified as inadequate training (83%); regulatory issues (76%); resistance by patients (56%), physicians (42%) and nurses (40%). Facilitators identified were use of treatment algorithms (94%), telehealth/m-health technology (92%) and adequate compensation for HCWs (80%). CONCLUSIONS: Our findings revealed key lessons for health systems and governments regarding team-based care implementation. Specifically, policies to facilitate additional training, optimise HCWs' roles within care teams, use of hypertension treatment protocols and telehealth/m-health technology will be essential to promote team-based care.

Clinical characteristics and treatment patterns of pregnant women with hypertension in primary care in the Federal Capital Territory of Nigeria: cross-sectional results from the hypertension treatment in Nigeria Program.

BACKGROUND: Hypertensive disorders of pregnancy, including hypertension, are a leading cause of maternal mortality in Nigeria. However, there is a paucity of data on pregnant women with hypertension who receive care in primary health care facilities. This study presents the results from a cross-sectional analysis of pregnant women enrolled in the Hypertension Treatment in Nigeria Program which is aimed at integrating and strengthening hypertension care in primary health care centres. METHODS: A descriptive analysis of the baseline results from the Hypertension Treatment in Nigeria Program was performed. Baseline blood pressures, treatment and control rates of pregnant women were analysed and compared to other adult women of reproductive age. A complete case analysis was performed, and a two-sided p value < 0.05 was considered statistically significant. RESULTS: Between January 2020 to October 2022, 5972 women of reproductive age were enrolled in the 60 primary healthcare centres participating in the Hypertension Treatment in Nigeria Program and 112 (2%) were pregnant. Overall mean age (SD) was 39.6 years (6.3). Co-morbidities were rare in both groups, and blood pressures were similar amongst pregnant and non-pregnant women (overall mean (SD) first systolic and diastolic blood pressures were 157.4 (20.6)/100.7 (13.6) mm Hg and overall mean (SD) second systolic and diastolic blood pressures were 151.7 (20.1)/98.4 (13.5) mm Hg). However, compared to non-pregnant women, pregnant women had a higher rate of newly diagnosed hypertension (65.2% versus 54.4% p = 0.02) and lower baseline walk-in treatment (32.1% versus 42.1%, p = 0.03). The control rate was numerically lower among pregnant patients (6.3% versus 10.2%, p = 0.17), but was not statistically significant. Some pregnant patients (8.3%) were on medications contraindicated in pregnancy, and none of the pregnant women were on aspirin for primary prevention of preeclampsia. CONCLUSIONS: These findings indicate significant gaps in care and important areas for future studies to improve the quality of care and outcomes for pregnant women with hypertension in Nigeria, a country with the highest burden of maternal mortality globally.

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.

Study design and protocol of a stepped wedge cluster randomized trial using a practical implementation strategy as a model for hypertension-HIV integration - the MAP-IT trial.

BACKGROUND: As people living with HIV (PLWH) experience earlier and more pronounced onset of noncommunicable diseases (NCDs), advancing integrated care networks and models in low-resource-high-need settings is critical. Leveraging current health system initiatives and addressing gaps in treatment for PLWH, we report our approach using a late-stage (T4) implementation research study to test the adoption and sustainability of a proven-effective implementation strategy which has been minimally applied in low-resource settings for the integration of hypertension control into HIV treatment. We detail our protocol for the Managing Hypertension Among People Living with HIV: an Integrated Model (MAP-IT) trial, which uses a stepped wedge cluster randomized trial (SW-CRT) design to evaluate the effectiveness of practice facilitation on the adoption of a hypertension treatment program for PLWH receiving care at primary healthcare centers (PHCs) in Akwa Ibom State, Nigeria. DESIGN: In partnership with the Nigerian Federal Ministry of Health (FMOH) and community organizations, the MAP-IT trial takes place in 30 PHCs. The i-PARiHS framework guided pre-implementation needs assessment. The RE-AIM framework will guide post-implementation activities to evaluate the effect of practice facilitation on the adoption, implementation fidelity, and sustainability of a hypertension program, as well as blood pressure (BP) control. Using a SW-CRT design, PHCs sequentially crossover from the hypertension program only (usual care) to hypertension plus practice facilitation (experimental condition). PHCs will recruit and enroll an average of 28-32 patients to reach a maximum of 960 PLWH participants with uncontrolled hypertension who will be followed longitudinally for BP outcomes. DISCUSSION: Given the need for integrated NCD-HIV care platforms in low-resource settings, MAP-IT will underscore the challenges and opportunities for integrating hypertension treatment into HIV care, particularly concerning adoption and sustainability. The evaluation of our integration approach will also highlight the potential impact of a health systems strengthening approach on BP control among PLWH.
