Exploring the impact of Patient Reported Outcome Measures (PROMs) among orthopaedic surgeons in mainland China: systematic review and survey-based study on hip and knee instruments

BACKGROUND: Patient Reported Outcome Measures (PROMs) are widely used in Europe and North America in a variety of areas including research, clinical governance, clinical registries and insurance ascertainment. The aim of this study was to assess commonly used knee and hip PROMs among Chinese surgeons and to gain an insight into their impact on evaluation of clinical outcomes. METHODS: 1. A systematic literature search of databases Medline, EMBASE, CINAHL and CNKI was performed from the earliest records to 22/07/2020 for knee instruments and 22/08/2020 for hip instruments, to retrieve Chinese Mandarin cross culturally adapted and validated knee and hip PROMs. 2. An 11-item electronic questionnaire was then designed under four domain categories. The survey was distributed via a ubiquitous online social media platform to orthopaedic surgeons. Responses were collected and analyzed. Output from 1. was used to populate parts of the survey questionnaire. RESULTS: The systematic online search yielded a total of 41 evaluation instruments, (10 hip and 31 knee); all of which were incorporated as response options. 234 viable questionnaires were retrieved with the largest group representing attending surgeons. 59.0% were familiar with the concept of PROMs among which 78.4% reported to have used PROMs themselves. In order of frequency of use, PROMs were purposed for clinical assessment (55.6%), research (40.7%), health regulation policies (18.6%) and insurance service requirements (10.6%). Implementation was prompted by both departmental (43.4%) and institutional policy (34.5%). 89.4% of PROMs users reported difficulties in the use of PROMs, with major barriers including license fees, limited access, inadequate training and burden of fill-out time (all > 40%). CONCLUSION: There is evidence of limited familiarity with knee and hip PROMs among orthopaedic surgeons. Barriers to their use are significant. Development of a Chinese language PROMs database would be helpful. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12891-021-04459-3.
