Background:
The effect of cannabis on pain management following open carpal tunnel release (CTR) surgery is unknown. The purpose of this study is to compare outcomes for patients with cannabis-related disorder (CRD) undergoing open CTR to a propensity-matched cohort of patients without CRD (no cannabis-related disorder [NCRD]).
Methods:
The TriNetX Research Network was queried to identify patients undergoing primary open CTR between January 2010 and December 2022. Patients with CRD were propensity matched to a NCRD cohort in a 1:1 ratio based on 7 characteristics. Rates of postoperative opioid prescriptions, emergency department (ED) services, and outpatient appointments were reported at 0-2, 2-6, and 6-12 weeks postoperatively.
Results:
A total of 925 CRD patients were propensity matched to 925 NCRD patients undergoing open CTR. Within 0-2 weeks postoperatively, CRD patients received significantly greater rates of opioid prescriptions compared to NCRD patients (30.9% and 25.6%, P = .011). No cannabis-related disorder (NCRD) patients presented for outpatient follow-up at significantly higher rates than CRD patients within 6 weeks postoperatively. CRD patients presented to the ED at significantly higher rates between 6 and 12 weeks postoperatively (11.0% vs. 8.0%, respectively, P = .027).
Conclusions:
Cannabis-related disorder (CRD) is associated with lower rates of outpatient follow-up but higher rates of postoperative opioid prescriptions and ED presentations following open CTR compared to a propensity-matched cohort of NCRD patients.
Level Of Evidence:
Cohort Study; Level III.
