Analysis of factors associated with patient-reported outcome (PRO) score completion rate one year after shoulder surgeries

Background: Patient-reported outcome measurements (PROMs) are important metrics for monitoring improvements following shoulder surgery. Despite the easy accessibility of electronic PROM surveys, completion rates vary, and factors predictive of survey completion for patients enrolled in medical survey follow-up after shoulder surgery remain largely unknown. The purpose of this study is to investigate survey completion rates for common shoulder procedures and identify factors predictive of PROM completion at one-year postoperatively. We hypothesize that the response rate to shoulder PROMs may vary by the shoulder procedure type after surgery. Methods: Patients undergoing total shoulder arthroplasty (TSA), rotator cuff repair (RCR), and instability surgery (Latarjet procedure [LP], and arthroscopic Bankart repair [ABR]) from 2019 to 2021 were prospectively enrolled. Each patient was administered PROM surveys via email preoperatively and at 2-weeks, 6-weeks, 3-months, 6-months, and 12-months following surgery. Demographics and socioeconomic characteristics were collected from our institutional database. The primary outcome studied was survey completion rate by procedure. Multivariable logistic regression was performed to identify factors predictive of completing 12-month follow-up. Results: A total of 514 (251 TSA, 194 RCR, and 69 instability surgery (35 LP, 34 ABR)) patients with an average age of 58 ± 15 years were included in this study. Overall, the 12-month survey completion rate for all procedures was 57.2%. TSA had the highest completion rate (64.9%), followed by RCR (52.1%), ABR (44.2%), and LP (42.9%). ABR and LP demonstrated more than a 50% drop in survey response at 2 weeks, and the RCR cohort demonstrated an increased attrition in survey response at the 6-month mark. Patients who completed the 12-month follow-up survey were older [61 ± 14 vs. 54 ± 17; P
