Implementation of a decentralized community-based treatment program to improve the management of Buruli ulcer in the Ouinhi district of Benin, West Africa

Background: Mycobacterium ulcerans infection, commonly known as Buruli ulcer (BU), is a debilitating neglected tropical disease. Its management remains complex and has three main components: antibiotic treatment combining rifampicin and streptomycin for 56 days, wound dressings and skin grafts for large ulcerations, and physical therapy to prevent functional limitations after care. In Benin, BU patient care is being integrated into the government health system. In this paper, we report on an innovative pilot program designed to introduce BU decentralization in Ouinhi district, one of Benin’s most endemic districts previously served by centralized hospital-based care. Methodology/Principal findings: We conducted intervention-oriented research implemented in four steps: baseline study, training of health district clinical staff, outreach education, outcome and impact assessments. Study results demonstrated that early BU lesions (71% of all detected cases) could be treated in the community following outreach education, and that most of the afflicted were willing to accept decentralized treatment. Ninety-three percent were successfully treated with antibiotics alone. The impact evaluation found that community confidence in decentralized BU care was greatly enhanced by clinic staff who came to be seen as having expertise in the care of most chronic wounds. Conclusions/Significance: This study documents a successful BU outreach and decentralized care program reaching early BU cases not previously treated by a proactive centralized BU program. The pilot program further demonstrates the added value of integrated wound management for NTD control. Author summary: The management of Buruli ulcer (BU) is complex, resulting in high costs to families and health systems. Early detection and treatment heals lesions without functional limitations. Decentralization of the management of this disease into the peripheral health system remains a challenge for national control programs. We report here on an innovative pilot intervention of decentralization of the management of BU in one of the most BU-endemic districts in Benin. The intervention was preceded by a culturally sensitive outreach campaign, which explained the disease’s symptoms and treatment options, and increased self-referral. It also included the treatment of all chronic ulcers free of charge. While serious cases of BU were still referred to the reference hospital for treatment, study results showed that 71% of BU cases could be treated in decentralized care; of these, 93% were successfully treated without functional limitations with antibiotics alone. The decentralized treatment option brought in new cases not previously treated by a proactive centralized BU program, and maintained total patient adherence to treatment protocols, in part through the support of community volunteer groups. The model developed in this pilot study may serve as the foundation and proof of concept for a larger community-based decentralized wound care agenda.
