Pragmatic Implementation of a Stratified Primary Care Model for Low Back Pain Management in Outpatient Physical Therapy Settings: Two-Phase, Sequential Preliminary Study.

Journal Article

BACKGROUND: The effectiveness of risk stratification for low back pain (LBP) management has not been demonstrated in outpatient physical therapy settings. OBJECTIVE: The purposes of this study were: (1) to assess implementation of a stratified care approach for LBP management by evaluating short-term treatment effects and (2) to determine feasibility of conducting a larger-scale study. DESIGN: This was a 2-phase, preliminary study. METHODS: In phase 1, clinicians were randomly assigned to receive standard (n=6) or stratified care (n=6) training. Stratified care training included 8 hours of content focusing on psychologically informed practice. Changes in LBP attitudes and beliefs were assessed using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) and the Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS). In phase 2, clinicians receiving the stratified care training were instructed to incorporate those strategies in their practice and 4-week patient outcomes were collected using a numerical pain rating scale (NPRS), and the Oswestry Disability Index (ODI). Study feasibility was assessed to identify potential barriers for completion of a larger-scale study. RESULTS: In phase 1, minimal changes were observed for PABS-PT and HC-PAIRS scores for standard care clinicians (Cohen d=0.00-0.28). Decreased biomedical (-4.5±2.5 points, d=1.08) and increased biopsychosocial (+5.5±2.0 points, d=2.86) treatment orientations were observed for stratified care clinicians, with these changes sustained 6 months later on the PABS-PT. In phase 2, patients receiving stratified care (n=67) had greater between-group improvements in NPRS (0.8 points; 95% confidence interval=0.1, 1.5; d=0.40) and ODI (8.9% points; 95% confidence interval=4.1, 13.6; d=0.76) scores compared with patients receiving standard physical therapy care (n=33). LIMITATIONS: In phase 2, treatment was not randomly assigned, and therapist adherence to treatment recommendations was not monitored. This study was not adequately powered to conduct subgroup analyses. CONCLUSIONS: In physical therapy settings, biomedical orientation can be modified, and risk-stratified care for LBP can be effectively implemented. Findings from this study can be used for planning of larger studies.
