"Eternally restarting" or "a branch line of continuity"? Exploring consequences of external shocks on community health systems in Haiti

Health systems resilience in fragile and conflict-affected settings: a systematic scoping review

BACKGROUND

Health systems resilience (HSR) research is a rapidly expanding field, in which key concepts are discussed and theoretical frameworks are emerging with vibrant debate. Fragile and conflict-affected settings (FCAS) are contexts exposed to compounding stressors, for which resilience is an important characteristic. However, only limited evidence has been generated in such settings. We conducted a scoping review to: (a) identify the conceptual frameworks of HSR used in the analysis of shocks and stressors in FCAS; (b) describe the representation of different actors involved in health care governance and service provision in these settings; and (c) identify health systems operations as they relate to absorption, adaptation, and transformation in FCAS.

METHODS

We used standard, extensive search methods. The search captured studies published between 2006 and January 2022. We included all peer reviewed and grey literature that adopted a HSR lens in the analysis of health responses to crises. Thematic analysis using both inductive and deductive approaches was conducted, adopting frameworks related to resilience characteristics identified by Kruk et al., and the resilience capacities described by Blanchet et al. RESULTS: Thirty-seven studies met our inclusion criteria. The governance-centred, capacity-oriented framework for HSR emerged as the most frequently used lens of analysis to describe the health responses to conflict and chronic violence specifically. Most studies focused on public health systems' resilience analysis, while the private health sector is only examined in complementarity with the former. Communities are minimally represented, despite their widely acknowledged role in supporting HSR. The documentation of operations enacting HSR in FCAS is focused on absorption and adaptation, while transformation is seldom described. Absorptive, adaptive, and transformative interventions are described across seven different domains: safety and security, society, health system governance, stocks and supplies, built environment, health care workforce, and health care services.

CONCLUSIONS

Our review findings suggest that the governance-centred framework can be useful to better understand HSR in FCAS. Future HSR research should document adaptive and transformative strategies that advance HSR, particularly in relation to actions intended to promote the safety and security of health systems, the built environment for health, and the adoption of a social justice lens.

Developing shared understanding of pre-eclampsia in Haiti and Zimbabwe using Theory of Change

Pre-eclampsia, a complex and multi-system disorder specific to pregnancy, is a leading cause of preventable maternal and perinatal deaths in low-resource settings. Early detection and appropriate intervention with management of hypertension, prevention of eclampsia and timely delivery are effective at reducing mortality and morbidity. Outcomes can be greatly improved with the provision and uptake of good quality care. Cultural contexts of maternal care, social practices and expectations around pregnancy and childbirth profoundly shape understanding and prioritisation when it comes to seeking out care. Few studies have addressed health education specifically targeting pre-eclampsia in low resource settings. The existing literature has limited descriptions of contextual barriers to care or of the intervention development processes employed. More engaging, holistic approaches to pre-eclampsia education for women and families that recognise the challenges they face and that support a shared understanding of the disorder, are needed. We describe our experience of developing a Theory of Change (ToC) as part of the co-production of educational resources for pre-eclampsia in Haiti and Zimbabwe.

Extreme Food Insecurity and Malnutrition in Haiti: Findings from a Population-Based Cohort in Port-au-Prince, Haiti

Haiti is one of the most food-insecure (FIS) nations in the world, with increasing rates of overweight and obesity. This study aimed to characterize FIS among households in urban Haiti and assess the relationship between FIS and body mass index (BMI) using enrollment data from the Haiti Cardiovascular Disease Cohort Study. FIS was characterized as no/low, moderate/high, and extreme based on the Household Food Security Scale. Multinomial logistic generalized estimating equations were used to evaluate the association between FIS categories and BMI, with obesity defined as BMI ≥ 30 kg/m2. Among 2972 participants, the prevalence of moderate/high FIS was 40.1% and extreme FIS was 43.7%. Those with extreme FIS had higher median age (41 vs. 38 years) and were less educated (secondary education: 11.6% vs. 20.3%) compared to those with no/low FIS. Although all FIS categories had high obesity prevalence, those with extreme FIS compared to no/low FIS (15.3% vs. 21.6%) had the lowest prevalence. Multivariable models showed an inverse relationship between FIS and obesity: moderate/high FIS (OR: 0.77, 95% CI: 0.56, 1.08) and extreme FIS (OR: 0.58, 95% CI: 0.42, 0.81) versus no/low FIS were associated with lower adjusted odds of obesity. We found high prevalence of extreme FIS in urban Haiti in a transitioning nutrition setting. The inverse relationship between extreme FIS and obesity needs to be further studied to reduce both FIS and obesity in this population.

Examining Roles, Support, and Experiences of Community Health Workers During the COVID-19 Pandemic in Bangladesh: A Mixed Methods Study

INTRODUCTION

Understanding community health workers' (CHWs) experiences of sustaining routine health care promotion and provision activities as well as their challenges in adopting new responsibilities within a dynamic context is critical. This study explored the roles and perspectives of CHWs within the government-led coronavirus disease (COVID-19) community health response in Bangladesh.

METHODS

We conducted a mixed methods study to explore the government's response to COVID-19 and its association with community health programming through a telephone-based survey of 370 government-employed CHWs. We also conducted 28 in-depth interviews with policy makers, program managers, CHW supervisors, and CHWs. We conducted exploratory and regression analysis of survey data and qualitative analysis of interview data.

RESULTS

The majority of CHWs reported receiving training related to COVID-19, including community-based prevention strategies from government and nongovernment stakeholders. Access to infection prevention supplies differed significantly by CHW cadre, and perspectives on the provision of adequate supplies varied qualitatively. CHWs reported slight decreases in routine work across all health areas early in the pandemic, and a majority reported added COVID-19-related responsibilities as the pandemic continued, including advising on signs/symptoms in their communities and referring suspected cases of COVID-19 for advanced facility care. Regression analyses showed that government support and integration of CHWs into their response-particularly being trained on COVID-19-predicted CHW capacity to advise communities on symptoms and provide routine services.

DISCUSSION

Government-employed CHWs in Bangladesh continued to provide health education and routine services in their communities despite pandemic- and response-related challenges. Varied support and differential CHW cadre-specific effects on COVID-19 awareness building in the community, referral, and routine service provision merit attention in Bangladesh's pluralistic community health system. While COVID-19 infection and government-mandated lockdowns restricted CHW mobility, the workers' capacity to continue service provision and education can be leveraged in vaccination and surveillance efforts moving forward.

Confirming-and testing-bonds of trust: A mixed methods study exploring community health workers' experiences during the COVID-19 pandemic in Bangladesh, Haiti and Kenya

Amidst the COVID-19 pandemic and national responses, trust (one's belief that a system acts in one's best interest) is important to consider. In community health systems, trust is embedded in relationships between clients, CHWs, and health system stakeholders. This mixed-methods study explores trust through the evolving COVID-19 crisis in Bangladesh, Haiti, and Kenya, where multi-country community health research was underway. We investigate the extent and ways trust between communities, community health workers (CHWs), and health system actors shift, including its relation to community fear and hostility, through self-reported positive and negative experiences of CHWs and policy/program stakeholders on a phone-based survey with 2,025 CHWs and 72 key informant interviews, including CHWs, in late 2020. On surveys, CHWs reported high levels of community trust (8/10 in Bangladesh and Kenya; 6/10 in Haiti) with over 60% reporting client relief in seeing their CHWs. About one-third of CHWs across countries reported experiencing instances of hostility from community members during the pandemic in the form of refused home-entry, ignored advice, or being shouted at. Multivariate analyses revealed that CHWs reporting more positive and fewer negative experiences is consistently associated with continuing routine work, doing COVID-19-related work, and greater community trust. Qualitative interviews showed that existing pre-pandemic trusting relationships withstood the early phase of COVID-19, mitigating negative community reactions toward CHWs and stigma towards COVID-positive individuals, maintaining routine health services, and sustaining appreciation for CHW-provided prevention information and emotional support. CHW-community and CHW-health system actor trust is strengthened when CHWs are well-resourced; CHW-community trust is strained by public frustration at the pandemic, associated restrictions, and sociopolitical stressors. Our study suggests that with adequate institutional support, bonds of trust can promote resilient community health systems during extended public health crises, through CHWs' commitment to mitigating misinformation, reducing stigma, maintaining routine service provision, and promoting COVID-19 prevention.

Food Insecurity and its Impact on Body Weight, Type 2 Diabetes, Cardiovascular Disease, and Mental Health

Purpose of Review

Food insecurity (FI) is a serious public health issue affecting 2 billion people worldwide. FI is associated with increased risk for multiple chronic diseases, including obesity, type 2 diabetes, cardiovascular disease, and mental health. We selected these four chronic diseases given their global prevalence and comorbid associations with each other. We evaluated the most recent literature published over the past 5 years and offer strategies for the screening of FI.

Recent Findings

Recent systematic reviews and meta-analyses report an association between FI and obesity in adult women as well as adult men and women living in low- and middle-income countries. Gender differences also were observed between FI and type 2 diabetes, such that adult women showed an increased risk for type 2 diabetes. This association was influenced by social determinants of health. Very low food security (i.e., high FI) was associated with increased risk for cardiovascular disease and a higher risk for cardiovascular disease mortality. Finally, several studies showed an association between FI and adverse mental health outcomes, including increased risk for stress, depression, anxiety, sleep disorders, and suicidal ideation.

Summary

FI and its negative association with body weight, type 2 diabetes, cardiovascular disease, and mental health provide a compelling rationale for identification of FI in clinical settings. Brief, well-validated screening measures are available in multiple languages. Despite the need for FI screening, many guidelines do not address its implementation. For this reason, more research and targeted interventions are needed to increase FI screening rates and close the loop in the coordination of resources.

Development and validation of a multi-dimensional scale to assess community health worker motivation

BACKGROUND

Ensuring that Community Health Workers (CHWs) are motivated is critical to their performance, retention and well-being - and ultimately to the effectiveness of community health systems worldwide. While CHW motivation is as multi-dimensional construct, there is no multi-dimensional measure available to guide programming. In this study, we developed and validated a pragmatic, multi-dimensional measure of CHW motivation.

METHODS

Scale validation entailed qualitative and survey research in Mali and Bangladesh. We developed a pool of work satisfaction items as well as several items assessing the importance of hypothesized sub-dimensions of motivation, based on the literature and expert consultations. Qualitative research helped finalize scale sub-dimensions and items. We tested the scale in surveys with CHWs in Mali (n = 152, 40% female, mean age 32) and Bangladesh (n = 76 women, mean age 46). We applied a split-sample exploratory/confirmatory factor analysis (EFA/CFA) in Mali, and EFA in Bangladesh, then assessed reliability. We also gauged convergent/predictive validity, assessing associations between scale scores with conceptually related variables.

RESULTS

The final 22-item scale has four sub-dimensions: Quality of supervision, Feeling valued and capacitated in your work, Peer respect and support, and Compensation and workload. Model fit in CFAs was good, as were reliabilities for the full scale (alpha: 0.84 in Mali, 0.93 in Bangladesh) and all sub-dimensions. To construct scores for the final scale, we weighted the scores for each sub-dimension by CHW-reported importance of that sub-dimension. Final possible range was -6 to +6 (sub-dimensions), -24 to +24 (full scale). Mean (standard deviation) of full-scale scores were 5.0 (3.3) in Mali and 14.5 (5.3) in Bangladesh. In both countries, higher motivation was significantly associated with higher overall interest in their work, feeling able to improve health/well-being in their community, as well as indicators of higher performance and retention.

CONCLUSIONS

We found that the Multi-dimensional Motivation (MM) scale for CHWs is a valid and reliable measure that comprehensively assesses motivation. We recommend the scale be employed in future research around CHW performance and community health systems strengthening worldwide. The scale should be further evaluated within longitudinal studies assessing CHW performance and retention outcomes over time.

The Client Empowerment in Community Health Systems Scale: Development and validation in three countries

BACKGROUND

Effectively measuring client empowerment is critical for monitoring and supporting empowerment through interventions, including via community health workers (CHWs) on the front line. Yet a comprehensive measure capturing the multidimensional aspects of client empowerment is not currently available. We aimed to develop and validate the Client Empowerment in Community Health Systems (CE-CHS) Scale in three countries.

METHODS

We used data from cross-sectional surveys from 2019-2020 with clients of CHWs in Bangladesh (n = 1384), Haiti (n = 616), and Kenya (n = 306). Nineteen candidate CE-CHS Scale items were adapted from existing health empowerment and sociopolitical control scales. Items spanned three hypothesized sub-domains: personal agency around health (eg, "I feel in control of my health"), agency in sharing health information with others (eg, "I feel confident sharing health information with my family/friends"), and empowerment in community health systems (eg, "Most facility/managers would listen to any concerns I raise"). Face and content validity of items were assessed via two focus group discussions in Haiti. For each country, we conducted split-sample exploratory/confirmatory factor analyses (EFA/CFA) and assessed internal consistency reliability. We assessed convergent validity by comparing final full-scale and sub-dimension scores to theoretically related variables.

RESULTS

All participants in Bangladesh and Kenya were female, as were 85% in Haiti. Mean age in Bangladesh and Kenya was around 25 years; 40 in Haiti. EFA/CFA resulted in a final 16-item CE-CHS Scale representing the three hypothesized sub-scales. Three items were dropped in EFA due to poor performance. CFA fit statistics were good for the full-scale and each sub-scale. The mean CE-CHS score (range 1 to 4) was 2.4 in in Bangladesh, 2.8 in Haiti, and 3.0 in Kenya. Cronbach's alpha and ordinal theta of the full and sub-scales were greater than 0.7. Increased empowerment was associated with increased trust in CHWs, influence of CHWs on empowerment, satisfaction with CHW services, number of CHW interactions, civic engagement, and education, with slight variations in magnitude and significance by country.

CONCLUSIONS

Findings suggest that the 16-item CE-CHS Scale is valid and reliable. This scale can be used to assess levels and determinants of, and changes in, client empowerment in future implementation research and monitoring of community health systems.

Measuring client trust in community health workers: A multi-country validation study

BACKGROUND

Client trust in community health workers (CHWs) is integral for improving quality and equity of community health systems globally. Despite its recognized conceptual and pragmatic importance across health areas, there are no quantitative measures of trust in the context of community health services. In this multi-country study, we aimed to develop and validate a scale that assesses trust in CHWs.

METHODS

To develop the scale, we used a consultative process to conceptualize and adapt items and domains from prior literature to the CHW context. Content validity and comprehension of scale items were validated through 10 focus group discussions with 75 community members in Haiti, and Kenya. We then conducted 1939 surveys with clients who interacted with CHWs recently in Bangladesh (n = 1017), Haiti (n = 616), and Kenya (n = 306). To analyze the 15 candidate scale items we conducted a split sample exploratory/confirmatory factor analysis (EFA/CFA), and then assessed internal consistency reliability of resulting set of items. Finally, we assessed convergent validity via multivariable models examining associations between final scale scores with theoretically related constructs.

RESULTS

Factor analyses resulted in a 10-item Trust in CHWs Scale with two factors (sub-scales): Health care competence (5 items) and Respectful communication (5 items). The qualitative data also underscored these two sub-domains. The full scale had good internal consistency reliability in Bangladesh, Haiti and Kenya (alphas 0.87, 0.86, and 0.92, respectively; all alphas for subscales were also > 0.7, most > 0.8). Greater scores on Trust in CHWs were positively associated with increased client empowerment, familiarity with CHWs, satisfaction with recent client-CHW interaction, and positive influence of CHW on client empowerment. Scale scores were not influenced by the age, sex, parity, education, and wealth quintiles in across countries and may be affected by contextual factors.

CONCLUSIONS

The Trust in CHWs Scale, which includes Health care competence and Respectful communication sub-scales, is the first such scale developed and validated globally. Our findings suggest this 10-item scale is a reliable and valid tool for quantifying clients' trust in CHWs, with potential utility for tracking and improving CHW and health systems performance over time.
