Capabilities, opportunities and motivations for integrating evidence-based strategy for hypertension control into HIV clinics in Southwest Nigeria.

ABSTRACT:

Background

Given the growing burden of cardiovascular diseases in sub-Saharan Africa, global donors and governments are exploring strategies for integrating evidence-based cardiovascular diseases prevention into HIV clinics. We assessed the capabilities, motivations and opportunities that exist for HIV clinics to apply evidence-based strategies for hypertension control among people living with HIV (PLHIV) in Nigeria.

Methods

We used a concurrent Quan-Qual- study approach (a quantitative first step using structured questionnaires followed by a qualitative approach using stakeholder meetings).We invited key stakeholders and representatives of HIV and non-communicable disease organizations in Lagos, Nigeria to 1) assess the capacity of HIV clinics (n = 29) to, and; 2) explore their attitudes and perceptions towards implementing evidence-based strategies for hypertension management in Lagos, Nigeria (n = 19)The quantitative data were analyzed using SPSS whereas responses from the stakeholders meeting were coded and analyzed using thematic approach and an implementation science framework, the COM-B (Capabilities, Opportunities, Motivations and Behavior) model, guided the mapping and interpretation of the data.

Results

Out of the 29 HIV clinics that participated in the study, 28 clinics were public, government-owned facilities with 394 HIV patients per month with varying capabilities, opportunities and motivations for integrating evidence-based hypertension interventions within their services for PLHIV. Majority of the clinics (n = 26) rated medium-to-low on the psychological capability domains, while most of the clinics (n = 25) rated low on the physical capabilities of integrating evidence-based hypertension interventions within HIV clinics. There was high variability in the ratings for the opportunity domains, with physical opportunities rated high in only eight HIV clinics, two clinics with a medium rating and nineteen clinics with a low rating. Social opportunity domain tended to be rated low in majority of the HIV clinics (n = 21). Lastly, almost all the HIV clinics (n = 23) rated high on the reflective motivation domain although automatic motivations tended to be rated low across the HIV clinics.

Conclusion

In this study, we found that with the exception of motivations, the relative capabilities whether physical or psychological and the relative opportunities for integrating evidence-based hypertension intervention within HIV clinics in Nigeria were minimal. Thus, there is need to strengthen the HIV clinics in Lagos for the implementation of evidence-based hypertension interventions within HIV clinics to improve patient outcomes and service delivery in Southwest Nigeria.

Project description:BackgroundEvidence-based task-strengthening strategies for hypertension (HTN) control (TASSH) are not readily available for patients living with HIV in sub-Saharan Africa where the dual burden of HTN and HIV remains high. We are conducting a cluster randomized controlled trial comparing the effectiveness of practice facilitation versus a self-directed control (i.e., receipt of TASSH with no practice facilitation) in reducing blood pressure and increasing the adoption of task-strengthening strategies for HTN control within HIV clinics in Nigeria. Prior to implementing the trial, we conducted formative research to identify factors that may influence the integration of TASSH within HIV clinics in Nigeria.MethodsThis mixed-methods study was conducted with purposively selected healthcare providers at 29 HIV clinics, followed by a 1-day stakeholder meeting with 19 representatives of HIV clinics. We collected quantitative practice assessment data using two instruments: (a) an adapted Service Availability and Readiness Assessment (SARA) tool to assess the capacity of the clinic to manage NCDs and (b) Implementation Climate Scale to assess the degree to which there is a strategic organizational climate supportive of the evidence-based practice implementation. The quantitative data were analyzed using descriptive statistics and measures of scale reliability. We also used the Consolidated Framework for Implementation Research (CFIR), to thematically analyze qualitative data generated and relevant to the aims of this study.ResultsAcross the 29 clinics surveyed, the focus on TASSH (mean=1.77 (SD=0.59)) and educational support (mean=1.32 (SD=0.68)) subscales demonstrated the highest mean score, with good-excellent internal consistency reliability (Cronbach's alphas ranging from 0.84 to 0.96). Within the five CFIR domains explored, the major facilitators of the intervention included relative advantage of TASSH compared to current practice, compatibility with clinic organizational structures, support of patients' needs, and intervention alignment with national guidelines. Barriers included the perceived complexity of TASSH, weak referral network and patient tracking mechanism within the clinics, and limited resources and diagnostic equipment for HTN.ConclusionOptimizing healthcare workers' implementation of evidence-based TASSH within HIV clinics requires attention to both the implementation climate and contextual factors likely to influence adoption and long-term sustainability. These findings have implications for the development of effective practice facilitation strategies to further improve the delivery and integration of TASSH within HIV clinics in Nigeria.Trial registrationClinicalTrials.gov , NCT04704336.

Project description:ObjectiveSub-Saharan Africa faces twin epidemics of HIV and noncommunicable diseases including hypertension. Integrating hypertension care into chronic HIV care is a global priority, but cost estimates are lacking. In the SEARCH Study, we performed population-level HIV/hypertension testing, and offered integrated streamlined chronic care. Here, we estimate costs for integrated hypertension/HIV care for HIV-positive individuals, and costs for hypertension care for HIV-negative individuals in the same clinics.DesignMicrocosting analysis of healthcare expenditures within Ugandan HIV clinics.MethodsSEARCH (NCT: 01864603) conducted community health campaigns for diagnosis and linkage to care for both HIV and hypertension. HIV-positive patients received hypertension/HIV care jointly including blood pressure monitoring and medications; HIV-negative patients received hypertension care at the same clinics. Within 10 Ugandan study communities during 2015-2016, we estimated incremental annual per-patient hypertension care costs using micro-costing techniques, time-and-motion personnel studies, and administrative/clinical records review.ResultsOverall, 70 HIV-positive and 2355 HIV-negative participants received hypertension care. For HIV-positive participants, average incremental cost of hypertension care was $6.29 per person per year, a 2.1% marginal increase over prior estimates for HIV care alone. For HIV-negative participants, hypertension care cost $11.39 per person per year, a 3.8% marginal increase over HIV care costs. Key costs for HIV-positive patients included hypertension medications ($6.19 per patient per year; 98% of total) and laboratory testing ($0.10 per patient per year; 2%). Key costs for HIV-negative patients included medications ($5.09 per patient per year; 45%) and clinic staff salaries ($3.66 per patient per year; 32%).ConclusionFor only 2-4% estimated additional costs, hypertension care was added to HIV care, and also expanded to all HIV-negative patients in prototypic Ugandan clinics, demonstrating substantial synergy. Our results should encourage accelerated scale-up of hypertension care into existing clinics.

Project description:BACKGROUND: In the human species, twin is a type of multiple birth in which the mother gives birth to two offspring from the same pregnancy. The occurrence and frequency of twinning, however, varies across human populations. The maternal age, socio-environmental factors, increase in the use of contraceptives, the race of human population, increase in the spontaneous abortion rate, and seasonal variations are among the factors that could influence twinning rate. Information on twinning rates in southwest Nigeria is limited. AIMS: This study presents information on the frequency of twinning, as well as its analysis by maternal age, in four urban settings in southwest Nigeria. This is with the aim of extending current knowledge on the frequency of twinning in southwest Nigeria and contributing to the demographic studies in the country. MATERIALS AND METHODS: Data on single births and twin births from January 1995 to December 2004 were collected from the Oyo State General Hospital (OSGH), Wesley Guild Hospital (WGH), Obafemi Awolowo University Teaching Hospital (OAUTH), and Ekiti State Specialist Hospital (ESSH) in Ogbomoso, Ilesa, Ile-Ife, and Ado-Ekiti respectively. These were analyzed by year and maternal age groups of 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, and 45-49 years according to the standard method. RESULTS: A frequency of twin births of 46.5 per 1000 deliveries and 46.2 per 1000 deliveries was recorded for Ilesa and Ile-Ife respectively. The frequency recorded for Ogbomoso and Ado-Ekiti was 38.5 and 22.1 per 1000 deliveries respectively. The overall average frequency of 40.2 per 1000 deliveries for the four hospitals ranks among the highest recorded rates of twin births in the world. The maternal age group of 25-29 years had the highest occurrence of twin births, while the lowest was recorded in the 45-49 years age group. CONCLUSION: This analysis reveals high incidence of twinning in the studied areas and supports previous assertion that the southwestern part of Nigeria has the highest twinning rate in the country and in the whole world. It is our opinion that diet, maternal history of twinning, and some socio-environmental factors may have influenced the results.

Project description:Background Socio-economic position (SEP) in adolescence may influence diet quality over the life course. However, knowledge of whether individual and environmental determinants of diet quality mediate the longitudinal association between SEP and diet quality is limited. This study examined whether and to what extent food-related capabilities, opportunities and motivations of adolescents mediated the longitudinal association between SEP in adolescence and diet quality in early adulthood overall and by sex. Methods Longitudinal data (annual surveys) from 774 adolescents (16.9 years at baseline; 76% female) from ProjectADAPT (T1 (baseline), T2, T3) were used. SEP in adolescence (T1) was operationalized as highest level of parental education and area-level disadvantage (based on postcode). The Capabilities, Opportunities and Motivations for Behaviour (COM-B) model was used as a framework to inform the analysis. Determinants in adolescence (T2) included food-related activities and skills (Capability), home availability of fruit and vegetables (Opportunity) and self-efficacy (Motivation). Diet quality in early adulthood (T3) was calculated using a modified version of the Australian Dietary Guidelines Index based on brief dietary questions on intake of foods from eight food groups. Structural equation modelling was used to estimate the mediating effects of adolescents’ COM-B in associations between adolescent SEP and diet quality in early adulthood overall and by sex. Standardized beta coefficients (β) and robust 95% confidence intervals (CI) were generated, adjusted for confounders (T1 age, sex, diet quality, whether still at school, and living at home) and clustering by school. Results There was evidence of an indirect effect of area-level disadvantage on diet quality via Opportunity (β: 0.021; 95% CI: 0.003 to 0.038), but limited evidence for parental education (β: 0.018; 95% CI: -0.003 to 0.039). Opportunity mediated 60.9% of the association between area-level disadvantage and diet quality. There was no evidence of an indirect effect via Capability or Motivation for either area-level disadvantage or parental education, or in males and females separately. Conclusions Using the COM-B model, the home availability of fruit and vegetables (Opportunity) of adolescents explained a large proportion of the association between area-level disadvantage in adolescence and diet quality in early adulthood. Interventions to address poor diet quality among adolescents with a lower SEP should prioritize environmental determinants of diet quality.

Project description:ObjectivesParticipation in the arts has well-documented benefits for health. However, participation in the arts is socially patterned, and it remains unclear why this is: what factors act as barriers or enablers of individual arts engagement. Therefore this study explored how individual characteristics predict individuals' capabilities, opportunities and motivations to engage in participatory arts activities.MethodsWe analysed data from 6,867 adults in the UK (61.2% female, average age 46.7 years) who engage infrequently in performing arts, visual arts, design and crafts, literature-related activities, or online, digital and electronic arts. We constructed a structural equation model to explore the relationship between demographic factors (including age, sex, ethnicity or socio-economic status), health factors (including physical and mental health) or social factors (including living alone, urban density, loneliness or socialising) and perceived barriers to arts engagement.ResultsIndividuals with poorer physical and mental health experienced more barriers affecting their perceived capabilities to engage in the arts, whilst individuals with poorer mental health also described experiencing more barriers affecting their motivations to engage. Individuals of lower SES reported more barriers in terms of opportunities to engage, whilst loneliness was related to more barriers around opportunities and motivations and living alone was associated with more opportunity barriers. Interestingly, adults who were older experienced fewer barriers relating to capabilities or opportunities, as did men, whilst being of white ethnicity was associated with fewer barriers across all three domains. Adults who were more socially engaged or who had poorer physical health experienced fewer barriers relating to motivations. Geographical area of dwelling was not related to any barriers.ConclusionsThis study has shown for the first time where the barriers leading to differential patterns of arts engagement lie. The findings could inform future behaviour change interventions designed to encourage arts engagement amongst individuals who are least likely to engage.

Project description:BackgroundDespite efforts to improve childhood immunization coverage in Nigeria, coverage has remained below the national acceptable level. In December 2019, we conducted an assessment of Missed Opportunities for Vaccination (MOV) in Ondo State, in Southwest Nigeria. The objectives were to determine the magnitude of, explore the reasons for, as well as possible solutions for reducing MOV in the State.MethodsThis was a cross-sectional study using a mixed-methods approach. We purposively selected 66 health facilities in three local government authorities, with a non-probabilistic sampling of caregivers of children 0-23 months for exit interviews, and health workers for knowledge, attitudes, and practices (KAP) surveys. Data collection was complemented with focus group discussions and in-depth interviews with caregivers and health workers. The proportion of MOV among children with documented vaccination histories were determined and thematic analysis of the qualitative data was carried out.Results984 caregivers with children aged 0-23 months were interviewed, of which 869 were eligible for inclusion in our analysis. The prevalence of MOV was 32.8%. MOV occurred among 90.8% of children during non-vaccination visits, and 7.3% during vaccination visits. Vaccine doses recommended later in the immunization series were given in a less timely manner. Among 41.0% of health workers, they reported their vaccination knowledge was insufficient. Additionally, 57.5% were concerned about and feared adverse events following immunization. Caregivers were found to have a low awareness about vaccination, and issues related to the organization of the health system were found to contribute towards MOV.ConclusionsOne in three children experienced a MOV during a health service encounter. Potential interventions to reduce MOV include training of health workers about immunization policies and practices, improving caregivers' engagement and screening of vaccination documentation by health workers during every health service encounter.

Project description:IntroductionThe prevalence of hypertension in sub-Saharan Africa is among the world's highest; however, awareness, treatment and control of hypertension in this region are suboptimal. Among other barriers, the overburdened healthcare system poses a great challenge for hypertension control. Community peer-support groups are an alternative and promising strategy to improve adherence and blood pressure (BP) control. The CLUBMEDS study aims to evaluate the feasibility and impact of adherence clubs to improve hypertension control in Nigeria.Methods and analysisThe CLUBMEDS study will include a formative (pre-implementation) qualitative evaluation, a pilot study and a process (postimplementation) qualitative evaluation. At the formative stages, focus group discussions with patient groups and in-depth interviews with healthcare providers, managers and key decision makers will be conducted to understand the feasibility, barriers and facilitators, opportunities and challenges for the successful implementation of the CLUBMEDS strategy. The CLUBMEDS pilot study will be implemented in two primary healthcare facilities, one urban and one rural, in Southeast Nigeria. Each adherence club, which consists of a group of 10-15 patients with hypertension under the leadership of a role-model patient, serves as a support group to encourage and facilitate adherence, BP self-monitoring and medication delivery on a monthly basis. A process evaluation will be conducted at the end of the pilot study to evaluate the acceptability and engagement with the CLUBMEDS strategy. To date, 104 patients were recruited and grouped into nine clubs, in which patients will be followed-up for 6 months.Ethics and disseminationThe study was approved by the University of Abuja Teaching Hospital and the Federal Teaching Hospital Abakaliki Human Research Ethics Committees and all patients provided informed consent. Our findings will provide preliminary data on the potential effectiveness and acceptance of this strategy in a hypertension context. Study findings will be disseminated via scientific forums.
