BACKGROUND The BetterBack model of care (MoC) for low back pain (LBP) was recently developed in Swedish physiotherapy (PT) primary care. OBJECTIVE To evaluate if PTs' adherence to LBP clinical practice guidelines (CPGs) improves after implementation of the BetterBack MoC (intervention). METHODS This was a stepped, single-blinded cluster randomized controlled trial. Patients nested in the three clusters were allocated to routine care (n = 222) or intervention (n = 278). The primary outcome was referral to specialist consultation. This was among five best practice recommendations divided into an assessment quality index (no referral to specialist consultation and no medical imaging) and a treatment quality index (use of educational interventions; use of exercise interventions; no use of non-evidence-based physiotherapy). For overall adherence, patients had to be treated with all five recommendations fulfilled. Logistic regression was used for between-group comparisons. RESULTS The proportion of patients receiving referral to specialist consultation during the PT treatment period was low in both groups with no between-group differences. However, patients in the intervention group showed significantly higher assessment quality index, treatment quality index and overall adherence compared to routine care. Adherence to the separate recommendations showed improved stratified number of visits, use of exercise was maintained high, patient educational intervention increased and use of non-evidence-based physiotherapy decreased. A reduction of medical imaging during the physiotherapy treatment period was also observed. CONCLUSIONS The adoption of CPGs could be substantially improved by introducing a MoC through PT training and supportive materials.
