Screening for adolescent idiopathic scoliosis is more accurate when performed by healthcare professionals compared to untrained parents: a diagnostic accuracy study

Background Many countries ended their professional scoliosis screening due to ongoing controversies. Discontinuation resulted in a shift of screening responsibility from trained healthcare professionals to untrained parents. Purpose To compare the diagnostic accuracy of picture-based scoliosis screening between parents and healthcare professionals. Methods In this cross-sectional diagnostic accuracy study, parents and healthcare professionals assessed pictures of 28 children (20 AIS & 8 non-scoliosis). Each child had two photographs (standing position & full-flexion during forward-bending test) that were presented simultaneously. Lumbar and thoracic curves were represented with a range in severity (10 to > 40°). The assessors had to answer whether they detected an abnormality that ought to be referred to a specialist. Measures of accuracy were calculated for both groups and various curve severities. Results All pictures were assessed by 101 parents and 122 healthcare professionals. The sensitivity for detecting scoliosis was significantly lower in untrained parents (63.8%, [95% CI: 61.7–65.9%]) compared to healthcare professionals (73.4%, [95% CI: 71.6–75.2%]; p
