The Effect of Patient-Reported Allergies on Patient-Reported Outcomes in Carpal Tunnel Release.

BACKGROUND

Patient-reported allergies have been shown to be a risk factor for poor surgical outcomes in a variety of orthopedic procedures. The relationship between patient-reported allergies and outcomes in carpal tunnel surgery remains unclear.

METHODS

A retrospective electronic medical chart review was conducted on 390 patients who underwent primary carpal tunnel releases, without concomitant procedures, who completed preoperative and postoperative Quick Disabilities of Arm, Shoulder, and Hand or Patient-Rated Wrist Evaluation scores, with a minimum of 1-year follow-up. Patient demographic data and patient-reported outcome measures were collected. Patients were grouped based on the number of allergies reported (≤3 allergies or ≥4 allergies), and statistical analysis was performed.

RESULTS

Three hundred and ninety patients were included in the analysis (347 patients [89.0%] with ≤3 allergies; 43 patients [11.0%] with ≥4 allergies). Patients were predominantly female (n = 243, 62.3%), and the median age at surgery was 61 years. Patients with ≥4 allergies were more likely to be female (88.4% vs 59.1%), older (64.3 years vs 60.3 years), and more likely to be taking psychotropic medication (51.2% vs 28.2%). No differences were seen in patient-reported outcomes at any time point preoperatively or postoperatively, with both groups showing similar postoperative improvement.

CONCLUSIONS

Patients with a high number of reported allergies have similar improvement in patient-reported outcomes following carpal tunnel release as low-allergy cohorts.
