Factors Affecting Community Participation in the CDTI Program in Morogoro, Tanzania

Abstract

Background: Up to 4 million people in Tanzania are at risk for the parasitic disease onchocerciasis. A treatment program, Community-Directed Treatment with Ivermectin (CDTI), has made significant gains in prevention and treatment. Understanding factors affecting participation could help boost treatment coverage and sustain gains made in controlling onchocerciasis in endemic areas. Purpose: To explore community-perceived factors related to participation in and sustainability of the CDTI program in southwest Tanzania. Methods: Multilevel triangulation design using surveys, focus group discussions (FGDs), and semistructured interviews to collect data in two villages in the Morogoro Rural District of Tanzania. In total, 456 villagers participated in the survey and 42 in FDGs. Five community-directed distributors (CDDs) and three community health workers were interviewed. Findings: High levels of awareness of onchocerciasis (90%) and methods of prevention and treatment (95%) were reported. Over 75% of participants knew how ivermectin was distributed and 74% have taken the drug. Over 90% of villagers knew that distribution of the drug was for treatment and prevention. Only 43% knew the cause of onchocerciasis. Through FGDs, villagers reported barriers to participation, including lack of comprehensive understanding of the disease, fears of medication, distrust of the method determining dose, lack of health education materials, insufficient CDD-resident communication, and inflexible drug distribution mechanisms. Conclusions: Sustaining programs without supporting growth of CDDs and reinforcing education of communities could lead to a decrease in treatment and an increase in the public health threat. This research uncovered a need for more effective community education and sensitization. Clinical Relevance: Understanding barriers to participation in communitybased programs can assist public health and community health nurses and key stakeholders including Ministries of Health and local and regional health systems in the development of education and support materials to enhance health literacy and encourage program participation.

Implementer and recipient perspectives of community-wide mass drug administration for soil-transmitted helminths in Kwale County, Kenya

“…Insufficiently trained drug distributors were likely to jeopardize uptake as their lack of knowledge endangered recipients' trust in the intervention. These findings are corroborated by studies on MDA for LF and onchocerciasis in Tanzania, where poor training was linked by respondents to limited ability to allay community members' concerns on drug safety [21,24]. With the exception of ensuring sufficient time is given towards training, previous studies have highlighted the importance of training without providing further detail on what factors contribute towards effective training [17,21].…”

“…Educating community members empowers communities and serves to increase participation in the desired health activity. As York et al [ 21 ] concluded when analyzing onchocerciasis control programs in Tanzania, programs’ success and sustainability is largely predicated on community sensitization.…”

Community drug distributors’ experiences and challenges faced in the implementation of community-directed treatment with ivermectin programme for onchocerciasis control in Ulanga, Tanzania

“…CDDs in Ulanga have a role in educating, motivating and ensuring that community members participate in the control of onchocerciasis by visiting households before ivermectin distribution to sensitize the community. Clearly, some of the challenges mentioned by CDDs in the implementation of the CDTI programme in Ulanga, such as hard-to-reach hamlets, doubt about the method of dose calculation and fear of side effects, were also revealed by another study performed in Tanzania by (12).…”
