American Physical Therapy Association Clinical Practice Guideline Implementation for Neck and Low Back Pain in Outpatient Physical Therapy: A Nonrandomized, Cross-sectional Stepped-Wedge Pilot Study
JOURNAL OF ORTHOPAEDIC & SPORTS PHYSICAL THERAPY(2022)
Abstract
OBJECTIVE: To determine whether a multifaceted implementation strategy for American Physical Therapy Association neck and low back pain clinical practice guidelines (CPGs) was associated with changes in clinician and patient outcomes. DESIGN: Cross-sectional stepped-wedge pilot study. METHODS: Physical therapy clinics (n = 9) were allocated to 1 of 4 clusters that varied by CPG implementation timing. Clinics crossed over from usual care (control) to CPG implementation (intervention) every 8 weeks and ended with a 24-week follow-up period. Implementation outcomes were measured at the clinician (perspectives and behaviors) and patient (pain and disability outcomes) levels. Descriptive statistics were used to summarize clinician perspectives and behaviors. Generalized linear mixed models were used to analyze patient-level outcomes data (pain and disability) and total number of physical therapy visits. RESULTS: Improvements in several clinician perspectives about CPGs were observed 8 weeks after training and sustained at 16 weeks (P<.05), although it is unclear whether these changes were meaningful. Training on CPGs was relevant to physical therapists and more acceptable at 16 weeks (P<.05). In a random sample (n = 764/1994. 38.3%), the overall rate of CPG classification was 65.0% (n = 497/764), and CPG intervention concordance was 712% (n = 354/497). Implementation of a CPG was not associated with final pain and disability scores (P>.05) but was associated with an approximate increase of 8% in total visits. CONCLUSION: Our multifaceted implementation strategy was associated with statistical changes in clinician perspectives and behaviors, but not in patient outcomes.
