Scoping Review of the Patient-Centered Literature Regarding Hip Osteoarthritis

Objective(s): The objective of this review is to characterize the literature regarding the illness experience of patients with hip osteoarthritis.

Data Sources: Two electronic databases (PUBMED and PsychInfo) were searched for English-language journal articles up until May 2022. The indexing terms for both searches were as follows: (("Osteoarthritis, Hip" AND (“pain” OR "Range of Motion, Articular" OR "Mobility Limitation" OR "Activities of Daily Living" OR "Quality of Life")) NOT (Arthroplasty OR Aquatic OR Rehabilitation OR Intervention OR Treatment)).

Study Selection: Four reviewers independently selected articles using previously determined exclusion and inclusion criteria; of 155 references, 89 full texts were assessed for eligibility.

Data Extraction: Reported study characteristics, independently extracted by four reviewers (with duplication of each study), included whether or not the study evaluated pain, mobility, quality of life and range of motion, as well as the measures used to evaluate those parameters.

Data Synthesis: Of the 89 studies screened via full-text review, 25 were included. The number of publications rose sharply the last two decades, almost doubling in the two prior ten-year periods, and a greater than sevenfold increase since 1999. Among the 25 studies; 96% reported pain, 60% reported QoL, 60% reported mobility, 20% reported range of motion, and 0% of studies reported history of exertion. There was a wide variety of measures used, but the WOMAC was used most often for pain and quality of life.

Conclusions: Considering over 9500 studies were found by searching "hip osteoarthritis" on the two electronic databases, the literature shows growing, but markedly little research into the lived experience of the disease. The wide variety of measures used to evaluate pain, mobility, RoM, QoL and HoE is concerning and it calls for a move to fewer, established methods. Future studies should be conducted to better understand the intersection of pain and mobility as they relate to activities of daily living for those with hip osteoarthritis.
