Factors associated with adherence to bracing in Ponseti management of clubfoot: a systematic scoping review

BackgroundClubfoot management according to the Ponseti method, including 4-5 years of bilateral foot abduction bracing to prevent relapse, is widely accepted as gold standard. Adherence to bracing is often low, despite non-adherence being associated with poor outcomes.ObjectivesThis systematic scoping review aimed to identify and synthesize factors associated with brace adherence and non-adherence in the Ponseti method, to identify strategies shown to improve adherence, and to provide a clinically meaningful synthesis of available evidence.MethodsThis scoping review utilized systematic search and formal guidance on conduct and reporting. Medline, SCOPUS, Informit, EmCare, CINAHL, and PEDro databases were searched for peer-reviewed primary research reporting factors associated with brace adherence or non-adherence during Ponseti management. Factors were identified, then grouped using inductive then deductive methods and reported in a narrative synthesis.ResultsA total of 413 studies were identified and 42 were included in the review: 31 quantitative and 11 qualitative, generally of low quality. Meta-analysis was not feasible. Factors associated with non-adherence were identified more often than with adherence, and findings for both were inconsistent. Fifty-three factors were investigated, with conflicting findings common. No studies evaluating strategies to improve brace adherence were identified.ConclusionsAvailable evidence does not indicate that any one factor or set of factors is consistently associated with adherence or non-adherence to bracing in Ponseti clubfoot management, and so clinically meaningful factors are proposed. Adequately powered longitudinal studies of adherence to bracing are required. Mixed methods approaches would help to inform and evaluate strategies to improve adherence, particularly those routinely recommended in clinical practice.
