Development of a model of interprofessional support interventions to enhance brace adherence in adolescents with idiopathic scoliosis: a qualitative study

PURPOSE: Brace treatment for adolescent idiopathic scoliosis is recognized as effective if the brace is worn as prescribed (20 to 23 hrs/day). Because of its negative biopsychosocial impact on adolescent patients’ quality of life, brace adherence is a common problem (average bracewear of 12 hrs/day). The purpose of this paper is to develop an interprofessional support intervention model to enhance brace adherence in adolescents with scoliosis. METHODS: We enrolled 9 health professionals working with braced patients to participate in individual interviews. Interview guides were built following the Information-Motivation-Strategy Model (DiMatteo et al., Health Psychol Rev 6:74-91, 2012) and the Interprofessional Care Competency Framework (Education UoTCfI, Toronto Acad Health Sci Network, 2017). Thematic analysis was performed to identify the most relevant concepts for designing the intervention model. A panel of 5 clinical experts was recruited to review and validate the intervention model. RESULTS: Participants suggested educational, motivational, functional, psychological and interprofessional teamwork strategies to improve the support provided to patients and parents and potentially increase brace adherence. Using the emerging themes and their relationships, we designed an Interprofessional Adherence Support (IPAS) intervention model that identifies the actors, activities, structure and intended impacts of the intervention. According to the expert panel, the IPAS model is highly relevant to respond to the brace adherence problem and has potential for implementation in practice. CONCLUSION: We designed an interprofessional support intervention model based on professional perspectives in response to the brace adherence problem in adolescents with scoliosis. Plans for implementation of the IPAS model at our scoliosis clinic are under development and considered essential for improving brace treatment outcomes.
