Trends in shoulder surgery patient-reported outcome measures

Patient-reported outcome measures (PROMs) are a vital part of the toolkit for the current practice of orthopedic surgery. We are witnessing the expansion of the use of PROMs in clinical practice and in research; the ultimate direction of this expansion is unclear. The purpose of this systematic review was to identify the trends in the use of PROMs in major upper limb publications over a 7-year period. We retrospectively reviewed all articles published in 6 of the most influential upper limb orthopedic journals based on impact factor from January 2013 to January 2020. PubMed, Medline, and Embase were used to access the abstracts for all articles published for this period. We included all articles related to shoulder arthroplasty, shoulder instability, rotator cuff surgery, and involving the use of PROMs. There were 4175 articles identified from the selected journals over the chosen time period, of which 607 were eligible for inclusion in the study. The number of articles reporting PROMs increased from 57 in 2013 to 115 in 2019, which was a 102% increase. The total number of PROM usages recorded was 1593 which was comprised of 63 different scoring systems, with each article using a median of 3 different PROMs. The most commonly used score in articles originating from North America was the American Shoulder and Elbow Surgeons score (216 uses in 273 articles; 78.1%), from Europe it was the Constant-Murley Score (129 uses in 183 articles; 70.4%), and from Asia it was the American Shoulder and Elbow Surgeons score (80 uses in 126 articles; 63.4%). The use of PROMs is evolving with an increasing prevalence of and diversity of PROMs being used in upper limb surgery. There is geographical variation in the use of PROMs, and a variety of systems used, with only 3 of the top 10 most used PROMs reporting on patient satisfaction or wellbeing. Given that a diverse range of PROMs study a diverse range of conditions and procedures, there may not be a need for a consensus on the best overall use of PROMs, but there may be ideal PROMs suited to answer specific questions.
