Feasibility of interdisciplinary evaluation in non-arthritic hip pain: A randomized trial

Background

Physical therapy and orthopaedic surgery are two common treatments for non-arthritic hip pain. Interdisciplinary evaluation across these disciplines may produce a more supportive treatment-planning process; however, the feasibility of such an evaluation remains unknown.

Hypothesis Objective

To assess the feasibility of an interdisciplinary evaluation with an orthopaedic surgeon and physical therapist for non-arthritic hip pain.

Study design

Observational feasibility study of a randomized controlled trial.

Methods

Participants were randomized to an interdisciplinary (surgeon + physical therapist) or standard (surgeon) evaluation in a hip preservation clinic. Recruitment rate was recorded. Retention rate was calculated for all variables of interest. Enrollment and refusal reasons were recorded as patient quotes and categorized by a single grader. Time spent in clinic was compared across groups using Mann Whitney U tests (P ≤ 0.05). Study clinicians were interviewed, and responses were categorized based on pre-determined themes.

Results

Eighty-one percent of eligible patients enrolled over a 15-month recruitment period. Willingness(n = 16), urgency to resolve pain(n = 10), financial compensation(n = 1), interest in research(n = 42), physical therapy(n = 6), or multiple-provider care(n = 15) were participants’ enrollment reasons; reason was not recorded for 22 participants. Time(n = 11), preference for single-provider care(n = 6), current physical therapy treatment(n = 1), and disinterest in physical therapy(n = 7) or research(n = 2) were refusal reasons of patients who did not enroll. Retention for primary variables of interest was 100% in both groups. Participants spent, on average, 23.5 min more time in clinic for the interdisciplinary evaluation compared to the standard (P < 0.001).

Conclusions

An interdisciplinary evaluation for patients with non-arthritic hip pain that included a physical therapist and orthopaedic surgeon in a hip preservation clinic was feasible and may better inform the treatment planning process.
