Patient-Reported Outcome Scores Are Comparable When Administered at Home or in Clinic Following Hip Preservation Surgery.

Purpose: To determine if the setting of administration (home vs clinic) results in significant differences in patient scores from questionnaires assessing hip and general physical function in a hip preservation patient population. Methods: Adult patients presenting to a hip preservation clinic completed the Modified Harris Hip Score (MHHS), the Physical Function Computed Automated Test (PFCAT), and the sports subscore of Hip Outcome Score (HOS) twice: on an electronic tablet during a clinic appointment and at home via website within 3 to 5 days of the clinic appointment. Patients were randomized into 2 groups to complete the home questionnaires before or after their clinic appointment. Mixed-effects multivariable linear regression analysis, including order of completion as a covariate (i.e., home or clinic first), was used to determine differences in home and clinic scores. Intraclass correlation coefficients were calculated to evaluate reliability. A Bland-Altman analysis evaluated the agreement between completions. Results: A total of 52 patients were included, 26 in each group. Mean age was 39.3 ± 12.2 years, and 38 of 52 (73%) patients were female. There was no significant difference between home and clinic completions of all 3 questionnaires (all Conclusions: The MHHS, PFCAT, and HOS have high repeatability and are, on average, not affected by settings of administration. When reviewing data on the level of the cohort, no distinction is required for patient-reported outcomes completed at home or clinic within 5 days of a clinical appointment. Level of Evidence: Level II, lesser quality randomized controlled trial.
