The impact of socio-economic factors on parental non-adherence to the Ponseti protocol for clubfoot treatment in low- and middle-income countries: A scoping review

Background The Ponseti treatment is considered the gold standard for clubfoot globally, but requires strong engagement from parents. The aim of this review is to assess the impact of socio-economic factors on the presence of drop-out, relapse or non-compliance during Ponseti treatment in low and middle-income countries (LMICs). Methods This scoping review includes all articles available from inception until 4.4.2022. All articles describing an association between one or more socio-economic factors and one or more adverse outcomes during the Ponseti treatment in an LMICs were considered for inclusion. Studies were identified by searching Medline/PubMed, Embase, Global Health and Global Index Medicus. Data extraction was done using Covidence extraction 2.0 by two independent reviewers. Findings A total of 281 unique references were-retrieved from the database searches, 59 abstracts were retained for full-text review, of which 19 studies were included in the final review. We grouped the identified socio-economic factors into 4 larger themes: poverty and physical accessibility of clubfoot clinics, presence of support systems, educational level of the parents, and household-level factors and cultural norms. Reduced access to care for girls was considered an important risk factor in South Asia and the Caribbean. Lack of family and community support was an issue raised more often in studies from Eastern Africa. The extreme heterogeneity among collected variables within a small sample of papers made it not possible to perform a meta-analysis. Interpretation The identified factors are very similar to the socio-economic factors identified in studies looking at the barriers parents and children face when seeking care initially. Poverty was identified as a cross-cutting risk factor in all 4 domains and the most important socio-economic risk factor based on this review, reconfirming poverty eradication as the challenge for the 21st century.
