Advanced practice physiotherapists can diagnose and triage patients with musculoskeletal disorders while providing effective care: a systematic review.

Questions: What is the diagnostic and surgical triage concordance between advanced practice physiotherapists (APPTs) and physicians? What is the clinical efficacy of advanced practice physiotherapy care compared with usual medical care?

Design: Systematic review with meta-analyses.

Literature Search: Medline, Embase, Cochrane CENTRAL and CINAHL were searched up to March 2022.

Study Selection Criteria: Concordance studies on diagnostic or surgical triage between APPTs and physicians and randomised controlled trials comparing the clinical efficacy of an advanced practice physiotherapy (APP) model of care compared with usual medical care for participants with musculoskeletal disorders.

Data Synthesis: Meta-analyses were performed for concordance and clinical outcomes. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to evaluate the certainty of evidence.

Results: Nineteen concordance studies (n = 1,745) and six randomised trials (n = 1,960) were included. Based on moderate-certainty evidence, the pooled Kappa for diagnostic concordance between APPTs and physicians was 0.76 (95% CI 0.68 to 0.85, n = 1,108). Based on high-certainty evidence, the pooled Kappa for surgical triage concordance was 0.71 (95% CI 0.63 to 0.78, n = 1,128). Based on moderate-certainty evidence, APP care resulted in a comparable or greater reduction in pain (MD -0.92 out of 10, 95% CI -1.75 to -0.10, n = 494) when compared with usual medical care at medium-term follow-up. Based on low-certainty evidence, APP care resulted in a comparable or greater reduction in disability (SMD -0.31, 95% CI -0.67 to 0.04, n = 535) when compared with usual medical care at medium-term follow-up.

Conclusion: Concordance between APPTs and physicians is probably good to very good for diagnosis and good to very good for surgical triage of musculoskeletal disorders. Patients with musculoskeletal disorders managed in an APP model of care probably report comparable or greater pain and disability reductions when compared with usual medical care.
