• PURPOSE
    • Few studies have examined the consumption of prescribed opioid medications after elective outpatient surgery. A better understanding of opioid consumption after elective upper-extremity surgery may lead to improved prescribing practices, decreased costs, and less leftover medication available for potential misuse. The goal of this study was to evaluate pain control and quantify the amount of leftover pain medication after outpatient carpal tunnel release.
  • METHODS
    • We performed a prospective study of patients scheduled for outpatient carpal tunnel surgery. All patients had failed nonsurgical treatment and had an electromyelogram/nerve conduction study confirming the clinical diagnosis. All patients were encouraged to remove the dressing on the first postoperative day. A total of 56 patients were initially enrolled in the study; 7 did not meet the inclusion criteria, which left 49 patients who completed the study. Average age was 57 years; 66% of patients were female. Information collected included analgesic prescribed, number of tablets consumed, and number of tablets remaining. Use of postoperative orthoses, complications, use of other analgesic medications, and reasons for not taking the prescribed analgesics were recorded.
  • RESULTS
    • Paracetamol with codeine and paracetamol with tramadol accounted for all prescriptions. Patients most frequently were given a prescription for 40 tablets. Average number of tablets consumed was 10 (range, 0-40 tablets). More than half of patients consumed fewer than 2 tablets. The average number of postoperative days of analgesic consumption was 2 (range, 0-7 days). Overall 1,531 tablets were leftover from the entire cohort.
  • CONCLUSIONS
    • This study demonstrates that excess prescription analgesics are being prescribed after carpal tunnel surgery.
  • TYPE OF STUDY/LEVEL OF EVIDENCE
    • Therapeutic IV.
