Abstract:

Background

Onchocerciasis, a neglected tropical disease (NTD) that causes blindness, is controlled via mass drug administration (MDA) where entire endemic communities are targeted with preventative chemotherapeutic treatment. However, in many settings, MDA coverage remains low. The purpose of this project was to determine if engaging communities in the development of implementation strategies improves MDA coverage.

Methods

This study took place in an intervention and a control commune in Benin, West Africa. We conducted rapid ethnography in each commune to learn about community member perceptions of onchocerciasis, MDA, and opportunities to increase MDA coverage. Findings were shared with key stakeholders and a structured nominal group technique was used to derive implementation strategies most likely to increase treatment coverage. The implementation strategies were delivered prior to and during onchocerciasis MDA. We conducted a coverage survey within 2 weeks of MDA to determine treatment coverage in each commune. A difference-in-differences design was used to determine if the implementation package effectively increased coverage. A dissemination meeting was held with the NTD program and partners to share findings and determine the perceived acceptability, appropriateness, and feasibility of implementing rapid ethnography as part of routine program improvement.

Results

During rapid ethnography, key barriers to MDA participation included trust in community drug distributors, poor penetration of MDA programs in rural or geographically isolated areas, and low demand for MDA among specific sub-populations driven by religious or socio-cultural beliefs. Stakeholders developed a five-component implementation strategy package, including making drug distributor trainings dynamic, redesigning distributor job aids, tailoring community sensitization messages, formalizing supervision, and preparing local champions. After implementing the strategy package, MDA coverage increased by 13% (95% CI: 11.0–15.9%) in the intervention commune relative to the control commune. Ministry of Health and implementing partners found the approach to be largely acceptable and appropriate; however, there was mixed feedback regarding the feasibility of future implementation of rapid ethnography.

Conclusions

Implementation research conducted in Benin, and indeed throughout sub-Saharan Africa, is often implemented in a top-down manner, with both implementation determinants and strategies derived in the global North. This project demonstrates the importance of participatory action research involving community members and implementers to optimize program delivery.

Abstract:

Background

Despite the significant success of deworming programs in reducing morbidity due to soil-transmitted helminth (STH) infections globally, efforts to achieve elimination of STH as a public health problem or to potentially interrupt transmission will require improving and intensifying surveillance. However, non-participation in surveillance threatens the ability of programs to adequately monitor program status and limited research has been conducted to investigate drivers of non-participation in stool-based surveillance.

Despite the significant success of deworming programs in reducing morbidity due to soil-transmitted helminth (STH) infections globally, efforts to achieve elimination of STH as a public health problem or to potentially interrupt transmission will require improving and intensifying surveillance. However, non-participation in surveillance threatens the ability of programs to adequately monitor program status and limited research has been conducted to investigate drivers of non-participation in stool-based surveillance.

Methodology/Principal findings

This mixed-methods exploratory sequential study took place in Comé, Benin in association with the DeWorm3 Project. Six focus group discussions were conducted with individuals invited to participate in annual DeWorm3 stool surveillance. Thematic analysis was used to identify facilitators and barriers to participation and inform the quantitative analysis. A mixed-effects logistic regression model was built using baseline DeWorm3 survey data to identify factors associated with non-participation. Qualitative and quantitative findings were merged for interpretation. Among the 7,039 individuals invited to participate in baseline stool surveillance, the refusal rate was 8.1%. Qualitative themes included: community members weighing community-level benefits against individual-level risks, circulating rumors about misuse of stool samples, interpersonal communication with field agents, and cultural norms around handling adult feces. The quantitative analysis demonstrated that adults were significantly less likely to provide a stool sample than school-aged children (OR:0.69, 95%CI: 0.55–0.88), a finding that converged with the qualitative results. Individuals from areas in the highest quartile of population density were more likely to refuse to participate (OR:1.71, 95%CI:1.16–2.52). Several variables linked to community-affinity aligned with qualitative results; residing mainly in the community (OR:0.36, 95%CI:0.20–0.66) and having lived in the community for more than 10 years (OR:0.82, 95%CI:0.54–1.25) decreased likelihood of refusal.

Conclusions/Significance

Optimizing STH surveillance will require that programs reimagine STH surveillance activities to address community concerns and ensure that no subpopulations are inadvertently excluded from surveillance data.

Author summary:

Soil-transmitted helminths (STH) are a group of intestinal parasites infecting approximately 1.5 billion people globally and resulting in significant adverse health outcomes. STH surveillance is conducted across endemic regions to assess prevalence of infection, to identify areas for mass drug administration implementation, and to monitor progress. The World Health Organization targets the elimination of STH as a public health problem in endemic settings with research currently being conducted to determine the feasibility of interrupting transmission of STH. In order to optimally design and manage programs towards these goals, and to verify whether elimination of STH as a public health problem has occurred, improvements in surveillance are needed. This mixed-methods study took place in Comé, Benin in association with the DeWorm3 Project, to identify drivers of non-participation in stool-based STH surveillance. This study found that certain individuals are more likely to refuse to participate in STH surveillance activities than others, including adults, individuals in urban areas, short-term residents in communities, and those perceiving their families to not be at risk for STH. As STH surveillance is intensified, programs will need to reimagine how surveillance is conducted to address community concerns and ensure that no subpopulations are inadvertently excluded from surveillance data.

Abstract:

Background

Current soil-transmitted helminth (STH) control programs target pre-school and school-age children with mass drug administration (MDA) of deworming medications, reducing morbidity without interrupting ongoing transmission. However, evidence suggests that STH elimination may be possible if MDA is delivered to all community members. Such a change to the STH standard-of-care would require substantial systems redesign. We measured baseline structural readiness to launch community-wide MDA for STH in Benin, India, and Malawi.

Methods

After field piloting and adaptation, the structural readiness survey included two constructs: Organizational Readiness for Implementing Change and Organizational Capacity for Change. Sub-constructs of organizational readiness include change commitment and change efficacy. Sub-constructs of organizational capacity include flexibility, organizational structure, and demonstrated capacity. Survey items were also separately organized into seven implementation domains. Surveys were administered to policymakers, mid-level managers, and implementers in each country using a five-point Likert scale. Item, sub-construct, construct, and domain-level medians and interquartile ranges were calculated for each stakeholder level within each country.

Results

Median organizational readiness for change scores were highest in Malawi (5.0 for all stakeholder groups). In India, scores were 5.0, 4.0, and 5.0 while in Benin, scores were 4.0, 3.0, and 4.0 for policymakers, mid-level managers, and implementers, respectively. Median change commitment was equal to or higher than median change efficacy across all countries and stakeholder groups.

Median organizational capacity for change was highest in India, with a median of 4.5 for policymakers and mid-level managers and 5.0 for implementers. In Malawi, the median capacity was 4.0 for policymakers and implementers, and 3.5 for mid-level managers. In Benin, the median capacity was 4.0 for policymakers and 3.0 for mid-level managers and implementers. Median sub-construct scores varied by stakeholder and country.

Across countries, items reflective of the implementation domain ‘policy environment’ were highest while items reflective of the ‘human resource’ domain were consistently lower.

Conclusion

Across all countries, stakeholders valued community-wide MDA for STH but had less confidence in their collective ability to effectively implement it. Perceived capacity varied by stakeholder group, highlighting the importance of accounting for multi-level stakeholder perspectives when determining organizational preparedness to launch new public health initiatives.
