Evaluating diabetes care in primary healthcare centers in Abuja, Nigeria: a cross-sectional formative assessment.

INTRODUCTION: Noncommunicable diseases (NCDs) are associated with 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 National policy, Nigeria has committed to implement the World Health Organization (WHO) Package of Essential Non-communicable Disease interventions for primary care. Implementing the intervention requires the availability of essential elements, including guidelines, trained staff, health management information systems (HMIS), equipment, and medications, in primary healthcare centers (PHCs). This study assessed the availability of the DM component of the WHO package, and the readiness of the health workers in these PHCs to implement a DM screening, evaluation, and management program to inform future adoption and implementation. 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 and October 2021. The SARA tool was adapted to focus on DM services and the 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] = 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 11 PHCs (36%). The study also reported high availability of paper-based HMIS (100%), and DM screening services using a glucometer (87%), but low availability of DM job aids (27%), treatment (23%), and national guidelines/protocols (0%). CONCLUSION: This formative assessment of PHCs' readiness to implement a DM screening, evaluation, and management program in Abuja demonstrated readiness to integrate DM care into PHCs regarding equipment, paper-based HMIS, and nonphysician health workers' availability. However, strategies are needed to promote DM health workforce training, provide DM management guidelines, and supply essential DM medications.

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.

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.

Fixed-dose combination therapy-based protocol compared with free pill combination protocol: Results of a cluster randomized trial.

Fixed-dose combination (FDC) therapy is recommended for hypertension management in Nigeria based on randomized trials at the individual level. This cluster-randomized trial evaluates effectiveness and safety of a treatment protocol that used two-drug FDC therapy as the second and third steps for hypertension control compared with a protocol that used free pill combinations. From January 2021 to June 2021, 60 primary healthcare centers in the Federal Capital Territory of Nigeria were randomized to a protocol using FDC therapy as second and third steps compared with a protocol that used the same medications in free pill combination therapy for these steps. Eligible patients were adults (≥18 years) with hypertension. The primary outcome was the odds of a patient being controlled at their last visit between baseline to 6-month follow-up in the FDC group compared to the free pill group. 4427 patients (mean [SD] age: 49.0 [12.4] years, 70.5% female) were registered with mean (SD) baseline systolic/diastolic blood pressure 155 (20.6)/96 (13.1) mm Hg. Baseline characteristics of groups were similar. After 6-months, hypertension control rate improved in the two treatment protocols, but there were no differences between the groups after adjustment (FDC = 53.9% versus free pill combination = 47.9%, cluster-adjusted p = .29). Adverse events were similarly low (<1%) in both groups. Both protocols improved hypertension control rates at 6-months in comparison to baseline, though no differences were observed between groups. Further work is needed to determine if upfront FDC therapy is more effective and efficient to improve hypertension control rates.

Characteristics and Patterns of Retention in Hypertension Care in Primary Care Settings From the Hypertension Treatment in Nigeria Program.

Background: More than 1.2 billion adults worldwide have hypertension. High retention in clinical care is essential for long-term management of hypertension, but 1-year retention rates are less than 50% in many resource-limited settings. Objective: To evaluate short-term retention rates and associated factors among patients with hypertension in primary health care centers in the Federal Capital Territory of Nigeria. Design, Setting, and Participants: In this cohort study, data were collected by trained study staff from adults aged 18 years or older at 60 public, primary health care centers in Nigeria between January 2020 and July 2021 as part of the Hypertension Treatment in Nigeria (HTN) Program. Patients with hypertension were registered. Exposures: Follow-up visit for hypertension care within 37 days of the registration visit. Main Outcomes and Measures: The main outcome was the 3-month rolling average 37-day retention rate in hypertension care, calculated by dividing the number of patients who had a follow-up visit within 37 days of their first (ie, registration) visit in the program by the total number of registered patients with hypertension during multiple consecutive 3-month periods. Interrupted time series analyses evaluated trends in retention rates before and after the intervention phase of the HTN Program. Mixed-effects, multivariable regression models evaluated associations between patient-, site-, and area council-level factors, hypertension treatment and control status, and 37-day retention rate. Results: In total, 10 686 patients (68.3% female; mean [SD] age, 48.8 [12.7] years) were included in the analysis. During the study period, the 3-month rolling average 37-day retention rate was 41% (95% CI, 37%-46%), with wide variability among sites. The retention rate was higher among patients who were older (adjusted odds ratio [aOR], 1.01 per year; 95% CI, 1.01-1.02 per year), were female (aOR, 1.11; 95% CI, 1.01-1.23), had a higher body mass index (aOR, 1.01; 95% CI, 1.00-1.02), were in the Kuje vs the Abaji area council (aOR, 2.25; 95% CI, 1.25-4.04), received hypertension treatment at the registration visit (aOR, 1.27; 95% CI, 1.07-1.50), and were registered during the postintervention period (aOR, 1.16; 95% CI, 1.06-1.26). Conclusions and Relevance: The findings suggest that retention in hypertension care is suboptimal in primary health care centers in Nigeria, although large variability among sites was found. Potentially modifiable and nonmodifiable factors associated with retention were identified and may inform multilevel, contextualized implementation strategies to improve retention.

Hypertension Treatment in Nigeria (HTN) Program: rationale and design for a type 2 hybrid, effectiveness, and implementation interrupted time series trial.

BACKGROUND: Hypertension is the most common cardiovascular disease in Nigeria and contributes to a large non-communicable disease burden. Our aim was to implement and evaluate a large-scale hypertension treatment and control program, adapted from the Kaiser Permanent Northern California and World Health Organization HEARTS models, within public primary healthcare centers in the Federal Capital Territory, Nigeria. METHODS: A type 2 hybrid, interrupted time series design was used to generate novel information on large-scale implementation and effectiveness of a multi-level hypertension control program within 60 primary healthcare centers in the Federal Capital Territory, Nigeria. During the formative phase, baseline qualitative assessments were held with patients, health workers, and administrators to inform implementation package adaptation. The package includes a hypertension patient registry with empanelment, performance and quality reporting, simplified treatment guideline emphasizing fixed-dose combination therapy, reliable access to quality essential medicines and technology, team-based care, and health coaching and home blood pressure monitoring. Strategies to implement and adapt the package were identified based on barriers and facilitators mapped in the formative phase, previous implementation experience, mid-term qualitative evaluation, and ongoing stakeholder and site feedback. The control phase included 11 months of sequential registration of hypertensive patients at participating primary healthcare centers, followed by implementation of the remainder of the package components and evaluation over 37 subsequent, consecutive months of the intervention phase. The formative phase was completed between April 2019 and August 2019, followed by initiation of the control phase in January 2020. The control phase included 11 months (January 2020 to November 2020) of sequential registration and empanelment of hypertensive patients at participating primary healthcare centers. After completion of the control phase in November 2020, the intervention phase commenced in December 2020 and will be completed in December 2023. DISCUSSION: This trial will provide robust evidence for implementation and effectiveness of a multi-level implementation package more broadly throughout the Federal Capital Territory, which may inform hypertension systems of care throughout Nigeria and in other low- and middle-income countries. Implementation outcome results will be important to understand what system-, site-, personnel-, and patient-level factors are necessary for successful implementation of this intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT04158154 . The trial was prospectively registered on November 8, 2019.

Characteristics, treatment, and control of hypertension in public primary healthcare centers in Nigeria: baseline results from the Hypertension Treatment in Nigeria Program.

BACKGROUND: There are limited data on large-scale, multilevel implementation research studies to improve hypertension diagnosis, treatment, and control rates at the primary healthcare (PHC) level in Africa. We describe the characteristics, treatment, and control rates of patients with hypertension in public PHC centers in the Hypertension Treatment in Nigeria Program. METHODS: Data were collected from adults at least 18 years at 60 public PHC centers between January 2020 and November 2020. Hypertension treatment rates were calculated at registration and upon completion of the initial visit. Hypertension control rates were calculated based on SBP and DBPs less than 140/90 mmHg. Regression models were created to evaluate factors associated with hypertension treatment and control status. RESULTS: Four thousand, nine hundred and twenty-seven individuals [66.7% women, mean (SD) age = 48.2 (12.9) years] were included. Mean (SD) SBP was higher in men compared with women [152.9 (20.0) mmHg versus 150.8 (21) mmHg, P = 0.001]. Most (58.3%) patients were on treatment at the time of registration, and by the end of the baseline visit, 89.2% of patients were on treatment. The baseline hypertension control rate was 13.1%, and control was more common among patients who were older [adjusted OR (95% CI) 1.01 [1.01 -1.02)], women [adjusted OR (95% CI) 1.30 (1.05- 1.62)], who used fixed dose combination therapy [adjusted OR (95% CI) 1.83 (1.49 -2.26)], and had higher education levels. CONCLUSION: This baseline report of the largest facility-based hypertension study in Africa demonstrates high hypertension treatment rates but low control rates.

Engaging stakeholders to identify gaps and develop strategies to inform evidence use for health policymaking in Nigeria.

Introduction: recent efforts to bridge the evidence-policy gap in low-and middle-income countries have seen growing interest from key audiences such as government, civil society, international organizations, private sector players, academia, and media. One of such engagement was a two-day virtual participant-driven conference (the convening) in Nigeria. The aim of the convening was to develop strategies for improving evidence use in health policy. The convening witnessed a participant blend of health policymakers, researchers, political policymakers, philanthropists, global health practitioners, program officers, students, and the media. Methods: in this study, we analyzed conversations at the convening with the aim to disseminate findings to key stakeholders in Nigeria. The recordings from the convening were transcribed and analyzed inductively to identify emerging themes, which were interpreted, and inferences are drawn. Results: a total of 630 people attended the convening. Participants joined from 13 countries. Participants identified poor collaboration between researchers and policymakers, poor community involvement in research and policy processes, poor funding for research, and inequalities as key factors inhibiting the use of evidence for policymaking in Nigeria. Strategies proposed to address these challenges include the use of participatory and embedded research methods, leveraging existing systems and networks, advocating for improved funding and ownership for research, and the use of context-sensitive knowledge translation strategies. Conclusion: overall, better interaction among the various stakeholders will improve the evidence generation, translation, and use in Nigeria. A road map for the dissemination of findings from this conference has been developed for implementation across the strata of the health system.

Importance of Community-Level Interventions During the COVID-19 Pandemic: Lessons from Sub-Saharan Africa.

Community-level strategies are important in ensuring adequate control of disease outbreaks especially in sub-Saharan African countries. Learning from public health responses to previous infectious disease outbreaks is important in shaping these responses to COVID-19. This study aims to highlight and summarize the evidence from community-level interventions during infectious disease outbreaks in sub-Saharan Africa (SSA). We conducted a scoping review of published literature on community-level interventions and strategies adopted in different infectious disease outbreaks in SSA. To obtain relevant studies, we searched EMBASE, CINAHL, MEDLINE, and Google Scholar in August 2020. Our search was based on the combination of keywords such as coronavirus, flu, Ebola, community, rural, strategies, impact, effectiveness, feasibility, Africa, developing countries, and SSA. Studies that met the inclusion criteria were selected and synthesized under the following distinct themes: health education, sensitization, and communications; surveillance; and service delivery. Our review highlights community-based strategies that have been tried and tested with varying outcomes for different outbreaks in different sub-Saharan African communities, we believe they will inform the selection of strategies to adopt in managing the COVID-19 pandemic at the community level. The important aspects of these strategies were highlighted, requirements for successful implementation and the possible challenges that might be encountered were also discussed. Achieving control of the COVID-19 pandemic in sub-Saharan African communities, will require concerted community-based and community-led strategies, which in turn rely on the availability of necessary socioeconomic resources, and the contextual adaption of these interventions.

Stakeholder perspectives to inform adaptation of a hypertension treatment program in primary healthcare centers in the Federal Capital Territory, Nigeria: a qualitative study.

BACKGROUND: Implementing an evidence-based hypertension program in primary healthcare centers (PHCs) in the Federal Capital Territory, Nigeria is an opportunity to improve hypertension diagnosis, treatment, and control and reduce deaths from cardiovascular diseases. This qualitative research study was conducted in Nigerian PHCs with patients, non-physician health workers, administrators and primary care physicians to inform contextual adaptations of Kaiser Permanente Northern California's hypertension model and the World Health Organization's HEARTS technical package for the system-level, Hypertension Treatment in Nigeria (HTN) Program. METHODS: Purposive sampling in 8 PHCs identified patients (n = 8), non-physician health workers (n = 12), administrators (n = 3), and primary care physicians (n = 6) for focus group discussions and interviews. The Primary Health Care Performance Initiative (PHCPI) conceptual framework and Consolidated Framework for Implementation Research (CFIR) domains were used to develop semi-structured interviews (Appendix 1, Supplemental Materials) and coding guides. Content analysis identified multilevel factors that would influence program implementation. RESULTS: Participants perceived the need to strengthen four major health system inputs across CFIR domains for successful adaptation of the HTN Program components: (1) reliable drug supply and blood pressure measurement equipment, (2) enable and empower community healthcare workers to participate in team-based care through training and education, (3) information systems to track patients and medication supply chain, and (4) a primary healthcare system that could offer a broader package of health services to meet patient needs. Specific features of the PHCPI framework considered important included: accessible and person-centered care, provider availability and competence, coordination of care, and proactive community outreach. Participants also identified patient-level factors, such as knowledge and beliefs about hypertension, and financial and transportation barriers that could be addressed with better communication, home visits, and drug financing. Participants recommended using existing community structures, such as village health committees and popular opinion leaders, to improve knowledge and demand for the HTN Program. CONCLUSIONS: These results provide information on specific primary care and community contextual factors that can support or hinder implementation and sustainability of an evidence-based, system-level hypertension program in the Federal Capital Territory, Nigeria, with the ultimate aim of scaling it to other parts of the country.

Capacity and site readiness for hypertension control program implementation in the Federal Capital Territory of Nigeria: a cross-sectional study.

BACKGROUND: Nigeria faces an increase in the burden of non-communicable diseases (NCDs), including cardiovascular diseases (CVDs), leading to an estimated 29% of all deaths in the country. Nigeria has an estimated hypertension prevalence ranging from 25 to 40% of her adult population. Despite this high burden, awareness (14-30%), treatment (< 20%), and control (9%) rates of hypertension are low in Nigeria. Against this backdrop, we sought to perform capacity and readiness assessments of public Primary Healthcare Centers (PHCs) to inform Nigeria's system-level hypertension control program's implementation and adaptation strategies. METHODS: The study employed a multi-stage sampling to select 60 from the 243 PHCs in the Federal Capital Territory (FCT) of Nigeria. The World Health Organization (WHO) Service Availability and Readiness Assessment was adapted to focus on hypertension diagnosis and treatment and was administered to PHC staff from May 2019 - October 2019. Indicator scores for general and cardiovascular service readiness were calculated based on the proportion of sites with available amenities, equipment, diagnostic tests, and medications. RESULTS: Median (interquartile range [IQR]) number of full-time staff was 5 (3-8), and were predominantly community health extension workers (median = 3 [IQR 2-5]). Few sites (n = 8; 15%) received cardiovascular disease diagnosis and management training within the previous 2 years, though most had sufficient capacity for screening (n = 58; 97%), diagnosis (n = 56; 93%), and confirmation (n = 50; 83%) of hypertension. Few PHCs had guidelines (n = 7; 13%), treatment algorithms (n = 3; 5%), or information materials (n = 1; 2%) for hypertension. Most sites (n = 55; 92%) had one or more functional blood pressure apparatus. All sites relied on paper records, and few had a functional computer (n = 10; 17%) or access to internet (n = 5; 8%). Despite inclusion on Nigeria's essential medicines list, 35 (59%) PHCs had zero 30-day treatment regimens of any blood pressure-lowering medications in stock. CONCLUSIONS: This first systematic assessment of capacity and readiness for a system-level hypertension control program within the FCT of Nigeria demonstrated implementation feasibility based on the workforce, equipment, and paper-based information systems, but a critical need for essential medicine supply strengthening, health-worker training, and protocols for hypertension treatment and control in Nigeria.

Social approaches to COVID-19 pandemic response: effectiveness and practicality in sub-Saharan Africa.

INTRODUCTION: the threat of the coronavirus disease 2019 (COVID-19) pandemic to health systems and communities in sub-Saharan Africa (SSA) is enormous. Social approaches such as distancing measures are essential components of the public health response to respiratory-related infectious disease outbreaks. Due to socio-economic and broader peculiarities of SSA countries, social approaches that were effective elsewhere may have limited practicality in these contexts, and if practical; may yield different or even adverse results. We highlighted the effectiveness of these social approaches and their practicality in SSA. METHODS: we conducted a comprehensive literature search through multiple databases, to identify articles relevant to social distancing. Findings were thematically summarized. RESULTS: our review found emerging and varying empirical evidence on the effectiveness of social approaches in the control and mitigation of the COVID-19 pandemic; thus, limiting its applicability in SSA contexts. Nonetheless, our review demonstrates that the effectiveness and practicality of social approaches in SSA contexts will depend on available resources; timing, duration, and intensity of the intervention; and compliance. Weak political coordination, anti-science sentiments, distrust of political leaders and limited implementation of legal frameworks can also affect practicality. CONCLUSION: to overcome these challenges, tailoring and adaptation of these measures to different but unique contexts for maximum effectiveness, and investment in social insurance mechanisms, are vital.

Primary healthcare planning, bottleneck analysis and performance improvement: An evaluation of processes and outcomes in a Nigerian context.

Operational planning of interventions defines roadmaps, timelines and resources necessary for translating policies into expected health outcomes along the evidence-policy-implementation continuum. However, bottlenecks often hinder the attainment of objectives and the timely delivery of intervention packages leading to sub-optimal performance of health systems. Bottleneck identification, analysis and removal approaches to planning, which requires key stakeholders' participation, have been recommended to improve health system outcomes in LMICs. This study demonstrates how integration of participatory action research (PAR) within a quality improvement model can help navigate the complexities of health system bottleneck analyses, planning and performance improvement in a Nigerian sub-national context. The study is based on data collected between June 2016 and June 2017, from Chikun LGA in Kaduna State Nigeria. PAR was integrated into a quality improvement model called DIVA (Diagnose-Intervene-Verify-Adjust) applied across selected interventions (eMTCT, Antenatal care, skilled birth attendance, immunization and Integrated Management of Childhood Illnesses). PAR was used to identify and analyse health system bottlenecks, as well as develop, monitor implementation and follow-up on action plans to address them. Evaluations were conducted involving 2 cycles of DIVA. The outputs (bottleneck analysis charts, driver diagrams, operational plans, M/E reports, etc.) from each cycle of the DIVA process were collated and analysed. Bottlenecks identified include availability of human resources for health, availability of health commodities as well as geographical accessibility. These had implications on acceptability and quality of services. Mean Improvements recorded were 20.4%, 14.0% and 10.8% and 11.2%, 7.5%; 5.5% (across eMTCT, maternal health and child health interventions) in the 1 st and 2nd DIVA cycles respectively. This study highlights processes and outcomes of integrating PAR in quality improvement design and operations in health intervention programmes with a focus on health systems strengthening in a Nigerian context. Implementing the DIVA model using a PAR approach may be considered an effective strategy for planning and implementing health interventions in comparable settings.
