Provider Perspectives on Use of Nighttime and Full-time Bracing to Treat Adolescent Idiopathic Scoliosis.

BACKGROUND

For patients with adolescent idiopathic scoliosis (AIS), full-time scoliosis braces are effective in preventing curve progression but are a source of stress for patients and families. Nighttime hypercorrective braces have minimal impact on daily life, but there is little evidence to guide prescription. It is not known how providers with expertise in scoliosis incorporate nighttime bracing into their routine clinical practice. The aim of this study is to assess provider perspectives and recommendations regarding the use of nighttime and full-time scoliosis bracing for patients with AIS.

METHODS

Providers engaged in nonoperative scoliosis management were invited to complete an online survey that included 12 scoliosis case scenarios. For each case scenario, respondents were asked to indicate their bracing recommendation and their willingness to randomize each case into a hypothetical clinical trial. The survey also queried respondents' use of nighttime and full-time bracing in their practice. Descriptive statistics were used to summarize findings; a linear mixed effects model was used to determine patient characteristics related to bracing recommendations and willingness to randomize.

RESULTS

A total of 214 respondents completed the survey; most had been in practice for >15 years (58%) and dedicate the majority of their practice to pediatric spine (57%). Just over half (54%) currently prescribe nighttime braces. Across case scenarios, most respondents recommended full-time bracing (70% to 92%); recommendations varied by curve type, curve magnitude, and skeletal maturity. For providers who use nighttime braces, the most important factors that led providers to prescribe nighttime over full-time braces were patient willingness to wear the brace (58%), skeletal maturity (57%), and curve type (56%).

CONCLUSIONS

Most providers preferred to prescribe full-time over nighttime braces. Providers were more willing to recommend a nighttime brace for patients with lumbar/thoracolumbar curves and those who were at lower risk for curve progression (ie, more skeletally mature and smaller curve magnitudes). Ultimately, results provide insights into current practice and will inform eligibility criteria and feasibility for a future study comparing nighttime and full-time braces.
