Multicenter Study Observational Study
Prospective observational study investigating the predictive validity of the STarT Back tool and the clinical effectiveness of stratified care in an emergency department setting.
To determine the predictive validity of the STarT Back tool (SBT) undertaken at baseline and 6 weeks to classify Emergency Department (ED) patients with LBP into groups at low, medium or high risk of persistent disability at 3 months. A secondary aim was to evaluate the clinical effectiveness of pragmatic risk-matched treatment in an ED cohort at 3 months. ⋯ Disability at baseline and SBT administered at 6 weeks more accurately predicted disability at 3 months than SBT at baseline in an ED population.
