Japanese physical therapist's evidence-to-practice gap in knee osteoarthritis clinical practice guidelines: A cross-sectional study.

OBJECTIVE: As management for osteoarthritis, clinical practice guidelines (CPGs) have been published worldwide with the aim of attaining optimal treatment and rehabilitation. However, we suspect a lack of knowledge of and/or adherence to osteoarthritis CPGs in physiotherapists' clinical practice. There may be an evidence-to-practice gap in knee osteoarthritis rehabilitation among Japanese physiotherapists. Therefore, we aimed to measure the level of knowledge and adherence to osteoarthritis CPGs within a cohort of Japanese physiotherapists.

METHODS: An online survey was created based on three appropriate and high-quality CPGs. The first two sections comprised 23 statements, and participants responded via a five-point Likert scale ("completely disagree" to "completely agree"). Consensus was defined as ≥70% agreement with a statement. In the second section, participants read clinical scenarios and selected what they considered to be the most appropriate management and interventions.

RESULTS: The survey was completed by 558 Japanese physiotherapists. The mean age of the participants included in the analysis was 34.8 years, 61 participants were female (13.7%). Consensus was attained in just 12 out of 23 items (52%). In the second section, none of the physiotherapists were considered to have good knowledge of CPGs, 85.2% were considered to have only partial knowledge, and 14.8% had no knowledge. Familiarity with the CPGs was therefore poor and there was clearly poor adherence to the recommended rehabilitation guidelines.

CONCLUSIONS: The level of knowledge and adherence to osteoarthritis CPGs within our cohort was poor, suggesting an evidence-to-practice gap in rehabilitation for knee osteoarthritis among Japanese physiotherapists.
