RESUMO
Integrated approaches to managing co-endemic neglected tropical diseases (NTDs) of the skin within primary healthcare services are complex and require tailoring to local contexts. We describe formative research in Atwima Mponua District in Ghana's Ashanti Region designed to inform the development of a sustainable intervention to improve access to skin NTD care. We employed a convergent, parallel, mixed-methods design, collecting data from February 2021 to February 2022. We quantitatively assessed service readiness using a standardised checklist and reviewed outpatient department registers and condition-specific case records in all government health facilities in the district. Alongside a review of policy documents, we conducted 49 interviews and 7 focus group discussions with purposively selected affected persons, caregivers, community members, health workers, and policy-makers to understand skin NTD care-seeking practices and the policy landscape. Outside the district hospital, skin NTD reporting rates in the surveyed facilities were low; supply chains for skin NTD diagnostics, consumables, and medicines had gaps; and health worker knowledge of skin NTDs was limited. Affected people described fragmented care, provided mostly by hospitals (often outside the district) or traditional healers, resulting in challenges obtaining timely diagnosis and treatment and high care-seeking costs. Affected people experienced stigma, although the extent to which stigma influenced care-seeking behaviour was unclear. National actors were more optimistic than district-level actors about local resource availability for skin NTD care and were sceptical of including traditional healers in interventions. Our findings indicate that improvement of the care cascade for affected individuals to reduce the clinical, economic, and psychosocial impact of skin NTDs is likely to require a complementary set of interventions. These findings have informed the design of a strategy to support high-quality, integrated, decentralised care for skin NTDs in Atwima Mponua, which will be assessed through a multidisciplinary evaluation.
RESUMO
Integrated strategies are recommended to tackle neglected tropical diseases of the skin (skin NTDs), which pose a substantial health and economic burden in many countries, including Ghana. We describe the development of an integrated and decentralised skin health strategy designed to improve experiences of skin NTDs in Atwima Mponua district in Ashanti Region. A multidisciplinary research team led an iterative process to develop an overall strategy and specific interventions, based on a theory of change informed by formative research conducted in Atwima Mponua district. The process involved preparatory work, four co-development workshops (August 2021 to November 2022), collaborative working groups to operationalise intervention components, and obtaining ethical approval. Stakeholders including affected individuals, caregivers, other community members and actors from different levels of the health system participated in co-development activities. We consulted these stakeholders at each stage of the research process, including discussion of study findings, development of our theory of change, identifying implementable solutions to identified challenges, and protocol development. Participants determined that the intervention should broadly address wounds and other skin conditions, rather than only skin NTDs, and should avoid reliance on non-governmental organisations and research teams to ensure sustainable implementation by district health teams and transferability elsewhere. The overall strategy was designed to focus on a decentralised model of care for skin conditions, while including other interventions to support a self-care delivery pathway, community engagement, and referral. Our theory of change describes the pathways through which these interventions are expected to achieve the strategy's aim, the assumptions, and problems addressed. This complex intervention strategy has been designed to respond to the local context, while maximising transferability to ensure wider relevance. Implementation is expected to begin in 2023.
RESUMO
BACKGROUND: A recent study detected cutaneous leishmaniasis (CL) in 31.9% of persons with skin ulcers in the Oti Region of Ghana, resulting in a need to investigate other potential causes of the unexplained skin ulcers. METHODOLOGY/PRINCIPAL FINDINGS: A community based cross-sectional study was conducted in the Oti region to investigate skin ulcers of undetermined aetiologies. To confirm a diagnosis of cutaneous leishmaniasis, Buruli ulcer, Haemophilus ducreyi ulcers, or yaws, DNA obtained from each patient skin ulcer sample was systematically subjected to polymerase chain reaction (PCR) for Leishmania spp., Mycobacterium ulcerans, Haemophilus ducreyi, and Treponema pallidum sub species pertenue. A total of 101 skin ulcer samples were obtained from 101 persons. Co-infection of more than one organism was observed in 68.3% of the samples. Forty (39.6%) participants had a positive result for Leishmania spp., 68 (67.3%) for Treponema pallidum sub. Sp. pertenue, and 74 (73.3%) for H. ducreyi. Twenty (19.8%) of the patient ulcers were simultaneously infected with Leishmania spp., Treponema pallidum sub. Sp. pertenue, and H. ducreyi. None of the patients' lesions yielded a positive result for Mycobacterium ulcerans. CONCLUSIONS/SIGNIFICANCE: This study detected single and mixed occurrence of the causative organisms of CL, yaws, and H. ducreyi cutaneous ulcers in CL endemic communities of the Oti Region in Ghana. These findings emphasize the importance of integrating multiple skin diseases on a common research platform and calls for the development of a comprehensive guideline for diagnosing and treating tropical ulcers in the study areas.
