Training community health workers to screen for cardiovascular disease risk in the community: experiences from Cape Town, South Africa

Multisectoral interventions for urban health in Africa: a mixed-methods systematic review

Increasing evidence suggests that urban health objectives are best achieved through a multisectoral approach. This approach requires multiple sectors to consider health and well-being as a central aspect of their policy development and implementation, recognising that numerous determinants of health lie outside (or beyond the confines of) the health sector. However, collaboration across sectors remains scarce and multisectoral interventions to support health are lacking in Africa. To address this gap in research, we conducted a mixed-method systematic review of multisectoral interventions aimed at enhancing health, with a particular focus on non-communicable diseases in urban African settings. Africa is the world's fastest urbanising region, making it a critical context in which to examine the impact of multisectoral approaches to improve health. This systematic review provides a valuable overview of current knowledge on multisectoral urban health interventions and enables the identification of existing knowledge gaps, and consequently, avenues for future research. We searched four academic databases (PubMed, Scopus, Web of Science, Global Health) for evidence dated 1989-2019 and identified grey literature from expert input. We identified 53 articles (17 quantitative, 20 qualitative, 12 mixed methods) involving collaborations across 22 sectors and 16 African countries. The principle guiding the majority of the multisectoral interventions was community health equity (39.6%), followed by healthy cities and healthy urban governance principles (32.1%). Targeted health outcomes were diverse, spanning behaviour, environmental and active participation from communities. With only 2% of all studies focusing on health equity as an outcome and with 47% of studies published by first authors located outside Africa, this review underlines the need for future research to prioritise equity both in terms of research outcomes and processes. A synthesised framework of seven interconnected components showcases an ecosystem on multisectoral interventions for urban health that can be examined in the future research in African urban settings that can benefit the health of people and the planet.Paper ContextMain findings: Multisectoral interventions were identified in 27.8% of African countries in the African Union, targeted at major cities with five sectors present at all intervention stages: academia or research, agriculture, government, health, and non-governmental.Added knowledge: We propose a synthesised framework showcasing an ecosystem on multisectoral interventions for urban health that can guide future research in African urban settings.Global health impact for policy and action: This study reveals a crucial gap in evidence on evaluating the long-term impact of multisectoral interventions and calls for partnerships involving various sectors and robust community engagement to effectively deliver and sustain health-promoting policies and actions.

The Medical Nemesis of Primary Health Care Implementation: Evidence From Ghana

Primary Health Care (PHC), based on the Alma Ata declaration, calls for the movement of responsibility, resources, and control away from medical systems and curative measures toward health promotion. However, PHC implementation in practice appears to be heavily influenced by medical systems with its own attendant effects on the attainment of PHC goals. This study therefore examines the extent and effects of medical systems influence on PHC implementation in Ghana. The study uses the thematic framework approach to qualitative data analysis to analyze data collected from PHC managers through interviews. Ethical clearance for the study was obtained from the Noguchi Memorial Institute for Medical Research. Findings suggest that PHC in practice is tied to the apron-strings of medical systems. While this has catalyzed successes in disease control programs and other medicine-based interventions, it has swayed PHC from its intended shift toward health promotion. Community ownership, participation, and empowerment in PHC is therefore lost in the maze of medical systems which reserves power over PHC decision making and implementation to medical professionals while focusing attention on treatment and curative services. Ultimately, PHC has gradually metamorphosed into mini-clinics instead of the revolutionary community-driven promotive services espoused by Alma Ata with concomitant effects on the attainment of Universal Health Coverage. Further, findings show how gradually, the primary in PHC is being used as a descriptor of the first or basic level of hospital-based care instead of a first point of addressing existing health problems using preventive, promotive, and other community driven approaches. Without a reorientation of health systems, significant efforts and resources are channeled toward empowering health workers instead of local communities with significant effects on the long term sustainability of health efforts and the attainment of UHC. The study recommends further studies toward practical means of reducing the influence of medical systems.

Effectiveness of community health workers on identification and mobilization of persons living with epilepsy in rural Rwanda using a validated screening tool

INTRODUCTION

Engagement and training of community health workers (CHWs) have demonstrated their value in different conditions. Despite repeat epilepsy trainings of CHWs in Northern Rwanda, the treatment gap remained high. We hypothesized that effectiveness of CHWs on mobilization of patients living with epilepsy (PwE) could be improved using a validated tool for epilepsy screening.

METHODS

CHWs associated with health centers (HCs) of Gataraga, Kimonyi and Karwasa attended a 1-day training on epilepsy and Limoges epilepsy screening questionnaire (Kinyarwanda version). Thereafter, CHWs screened households in their villages for persons with one or more positive answer. CHWs then accompanied positively screened persons to a consultation for clinical evaluation and diagnosis by neurologists, and demographic data were collected. CHW variables were collected retrospectively.

RESULTS

A total of 1308 persons were screened positive by 281 CHWs. Clinical diagnosis of epilepsy was confirmed in 589 and in 93 additional unscreened PwE, presenting voluntarily at the consultation. Pre-intervention number of 48 PwE increased to 682 after, a 14.2-fold increase. The overall treatment gap amounted to 93.0%. The age distribution of male PwE preponderance at younger age inverted to females at older age. CHW characteristics showed non-significant differences within and across HCs. Logistic regression did not relate CHW age, gender, and experience to screening results.

DISCUSSION

Equipping CHWs with a validated screening tool was effective in identifying and mobilizing PwE in a short time frame and offers opportunity for future scaling. Nonetheless, barriers to sustainability of care will need to be addressed before.

Characteristics and Outcomes of Community Health Worker Training to Improve the Prevention and Control of Cardiometabolic Diseases in Low and Middle-Income Countries: A Systematic Review

Community health workers (CHWs) play an important role in controlling non-communicable diseases in low- and middle-income countries. The aim of this review was to describe the characteristics and outcomes of CHW training programs that focused on the prevention and control of cardiometabolic diseases in low- and middle-income countries (LMICs). Medline, CINAHL Complete, Academic Search Complete, Directory of Open Access Journal, ScienceDirect, ERIC, Gale Academic, and OneFile). Studies that described the training programs used to train CHWs for prevention and control of cardiovascular diseases and type2 diabetes mellitus in LMICs. Only studies that evaluated the outcomes of training programs in at least one of the 4 levels of Kirkpatrick's training evaluation model were included in the review. CHWs who underwent training focused on the prevention and control of cardiovascular disease and type 2 diabetes mellitus. We summarized the resulting evidence using qualitative synthesis through a narrative review. Training outcomes were assessed in relation to (1) CHW reactions to training, their degree of learning, and their behaviors following training, and (2) changes in biochemical and anthropometric indicators in target populations following the CHW program implementation. PROSPERO (CRD42020162116). Thirty-two studies were included. Methods used to train CHWs included: face-to-face lectures, interactive group activities, and blended teaching with online support. Training focused on identifying people with elevated risk of cardiometabolic diseases and their risk factors as well as supporting people to adopt healthy lifestyles. Many studies that utilized trained CHWs did not publish CHW training methods and evaluations, and therefore could not be included in this study. Training programs resulted in an increase in knowledge and skills among CHWs demonstrating that there are certain activities that can be shifted to CHWs following training.

Assessment of cardiovascular disease risks using Framingham risk scores (FRS) in HIV-positive and HIV-negative older adults in South Africa

The relationship between HIV and cardiovascular diseases (CVDs) remains complex. The aim of this study was to estimate the 10-year CVD risk among HIV-positive and HIV-negative people. The validated Framingham Risk Score (FRS) based on the Framingham Heart study was used to predict the CVD risk. Data for this analysis came from a 2016 cross-sectional study of South African community-dwelling older adults (≥50 years). Logistic regression models were constructed to assess the association between CVD risk and HIV. 403 respondents with a mean age 60 (SD = 6.7) years were enrolled, of whom 70% were female, 75% black African, 21.9% smokers, 77.2% never did any vigorous physical activity, and 17% were HIV-positive. The average 10-year CVD risk was 17%; significantly higher in men than women (23.2 vs 14.3%, p < 0.001). Overall, 33% had low CVD risk (FRS < 10%), 39% intermediate (FRS 10-19%) and 28% high risk (FRS ≥ 20%). Furthermore, participants who were HIV-positive were less likely than HIV-negative participants to have high CVD risk (aOR 0.27, 95% CI 0.11-0.66, p = 0.004). These findings of HIV-positive respondents having lower CVD risk than HIV-negative respondents could be due to three issues i) HIV-positive people having lesser cardio-metabolic disease risk factors; ii) possibly higher health care utilization by HIV-positive people; and/or iii) the neglect of HIV-negative people in HIV focused health systems. Periodic cardiovascular disease monitoring using tools like the Framingham Risk Scores is needed. Furthermore, studies with more robust designs are needed to further elucidate the relationship between HIV and CVD risks in HIV endemic sub-Saharan Africa.

The Role of Noncommunicable Diseases in the Pursuit of Global Health Security

Noncommunicable diseases and their risk factors are important for all aspects of outbreak preparedness and response, affecting a range of factors including host susceptibility, pathogen virulence, and health system capacity. This conceptual analysis has 2 objectives. First, we use the Haddon matrix paradigm to formulate a framework for assessing the relevance of noncommunicable diseases to health security efforts throughout all phases of the disaster life cycle: before, during, and after an event. Second, we build upon this framework to identify 6 technical action areas in global health security programs that are opportune integration points for global health security and noncommunicable disease objectives: surveillance, workforce development, laboratory systems, immunization, risk communication, and sustainable financing. We discuss approaches to integration with the goal of maximizing the reach of global health security where infectious disease threats and chronic disease burdens overlap.

What Is the Impact of a Context-Specific Training Program for Home-Based Carers? An Evaluation Study

Introduction: In South Africa (SA), home-based carers (HBCs) play a crucial role at the community level for non-communicable diseases (NCDs) including diabetes mellitus (DM) public health care. The work of HBCs requires them to be knowledgeable about diabetes, and lack of knowledge has implications on their roles for the provision of health information and dietary advice. HBCs need to be provided with specific training to develop their knowledge and skills necessary to enable them to provide care to people with diabetes (PWD) because organizations need to benefit from a pool of well-trained HBCs. Therefore, a training program was developed to improve care for chronic conditions based on local needs. Aim: To implement and evaluate the training program for the HBCs for PWD in Ga-Dikgale village. Methods: HBCs working at Ga- Dikgale villages in four clinics—namely, Dikgale, Seobi Dikgale, Sebayeng, and Makotopong—participated voluntarily. Fifty-five (55) HBCs who attended the training program completed satisfaction survey tools, and furthermore, 45 HBCs completed both pre-training and post-training knowledge questionnaires. Training divided into two sessions which each lasted for two days was conducted. Satisfaction with the training, improvement of knowledge, and perceived impact on daily practice were evaluated using both qualitative and quantitative approaches. Results: Quantitative results indicate that 72% had poor knowledge of pre-training and only 9% post-training. They scored more in a post-test with the following differences: Post-test (mean = 6.00, SD = 1.26); pre-test (mean = 3.31, SD = 1.77). The t-test results indicated the difference to be significant, t = −9.241, p = 0.000. From the qualitative results, the themes that emerged during data analysis from group discussions were HBCs’ achievements from the training, challenges related to diabetes and diet, and suggestions for further training. Conclusions: A context-specific training increased diabetes knowledge among the HBCs for PWD. The results highlighted the importance of training in improving the knowledge of HBCs about the care of PWD. The improvement in diabetes knowledge among HBCs needs to be maintained and sustained to achieve major health benefits for PWD.

Cardiovascular diseases and risk factors knowledge and awareness in people with type 2 diabetes mellitus: a global evaluation

AIM

Cardiovascular diseases (CVD) are the leading cause of death in people living with type 2 diabetes mellitus (T2D). The aim of this study was to explore the knowledge and awareness of CVD and related risk factors in people living with T2D, globally.

METHODS

A questionnaire consisting of 17 questions was used to conduct the Taking Diabetes to Heart survey, between September 2017 and May 2018 among people living with T2D. All categorical variables are presented as numbers and percentages. Pearson's chi-square test and Fisher's exact test were used to assess the association between categorical variables.

RESULTS

A total of 12,695 respondents living with T2D in 133 countries completed the questionnaire. Almost half of the respondents (44%) reported having lived with diabetes for more than nine years. Only one in six (17%) considered themselves at high risk of CVD, which was surprising given that almost all the respondents had at least one CVD risk factor and around 28% of respondents had experienced one or more CVD events in the past. Although the majority of the respondents indicated they have had CVD risk factors, one in six (17%) had never discussed their risk with a health professional (HP). Furthermore, one in eleven (9%) did not know about CVD and its associated risk factors.

CONCLUSION

To mitigate the prevalence of CVD in people living with diabetes, it is required to work with HP to increase knowledge and awareness of people with T2D about diabetes complications, in particular CVD.
