Purpose:
We sought to determine whether subjective clinical improvement immediately after carpal tunnel release (CTR) was captured by Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE), Physical Function (PF), Pain Interference (PI), and Depression.
Methods:
Between September 2018 and January 2020, patients presenting to a single academic medical center hand clinic were asked to complete PROMIS UE, PF, PI, and Depression computer adaptive tests. In addition, patients who had CTR were asked to answer the following at their first postoperative clinic visit: "Since my last clinic visit, my condition is: (1) much better; (2) mildly better; (3) no change; (4) mildly worse; (5) much worse." For each patient, the last clinic visit was the final preoperative visit. The PROMIS domain scores were compared before and after surgery using paired t tests. The percentage of patients subjectively reporting better symptoms was calculated.
Results:
A total of 156 patients fit our inclusion criteria. The average number of days between the final preoperative visit and CTR was 7 (range, 0-30), and the average number of days between CTR and the first postoperative visit was 9 (range, 3-21). A total of 116 patients (74%) reported their carpal tunnel syndrome was better at their first postoperative visit. However, PROMIS UE, PF, and PI scores were significantly worse at the first postoperative visit, although not at clinically appreciable levels. There was no statistical or clinical difference in PROMIS Depression scores from pre- to postoperative time points.
Conclusions:
Nearly 75% of patients subjectively report their carpal tunnel syndrome is better at their first follow-up visit within 3 weeks of CTR; however, PROMIS does not capture this improvement.
Clinical Relevance:
Hand surgeons evaluating patients shortly following CTR should be aware of the potential limitation of PROMIS to accurately capture immediate postoperative clinical outcomes. Disease-specific Patient-Reported Outcome Measures, such as the Boston Carpal Tunnel Questionnaire, may be preferred during this immediate postoperative timeframe.
