Evaluation of a PRImary-ORthopaedic (PRIOR) low back pain care model in Hong Kong: a pilot study
Abstract Introduction: Low back pain (LBP) is a common and disabling condition with significant socioeconomic burden. A LBP care delivery model with collaborative input from primary care physicians, orthopaedic surgeons and allied health professionals has been implemented in one of the local tertiary hospital to streamline LBP care.Objective: To evaluate the preliminary effectiveness of the primary-orthopaedic (PRIOR) LBP care model.Methods: This was a 6-month quasi-experimental study with pre and post assessment. Participants (N=30) with chronic LBP were recruited and stratified by physiotherapists at the triage station located at Orthopaedic Special Outpatient Clinic. Eligible participants were referred to attend primary physicians with trained musculoskeletal skills for risk-matched treatment at Family Medicine Clinic. Patient-specific outcomes included the acceptance rate, Roland Morris Disability (RMD) scores, the self-pain efficacy scores (PSE) scores and the Euro-Qol-5D. The health service outcomes included the waiting time, discharge rate, adherence rate and healthcare resources utilization. Results: Of the 33 participants screened, 30 were eligible and enrolled for the study, the recruitment rate was 91% (X2=0.569, p=0.451). At 6 months, participants reported overall improvement of the RMD scores (β coefficient -4.3, 95% confidence interval CI -5.9 to – 2.7, P<0.001) and PSEQ scores (β coefficient 7.3, 95% CI 3.0-12.0, P=0.002). The waiting time of the FM clinic was 11.6 ±1.6 weeks, the overall discharge rate was 73%, and the adherence rate was 87%.Conclusions: The study suggested that the PRIOR LBP model could potentially improve the clinical outcomes of LBP patients and enhance the overall LBP health service delivery.
