Postoperative Opioid Prescription and Use After Outpatient Vascular Access Surgery

Larger opioid prescriptions are associated with increased consumption without improvements in pain, and the majority of opioids prescribed go unused. We examined postoperative opioid prescription and use in patients undergoing vascular access surgery, where preoperative opioid exposure is common.

A retrospective analysis was conducted in adult CKD patients who underwent outpatient vascular access surgery. Patients were surveyed by telephone >2 weeks after surgery to assess pain level and opioid and non-opioid medication use.

Of 117 patients contacted, 76 responded (65% response rate), with a median (interquartile range) age of 56 (42-69) years. Sixty-three patients (83%) were prescribed an opioid postoperatively. Respondents were prescribed 60 (38-75) oral morphine equivalents (OMEs) and consumed 0 (0-15) OMEs over 1 day with a pain score of 5 out of 10. Thirty-nine patients (>50%) used no opioids. There were no differences in postoperative opioid prescribing or use in patients with recent opioid exposure compared to patients without. Patients who underwent arteriovenous fistula (AVF) creation (short surgical incision procedure) were prescribed 60 (38-75) OMEs, compared with 75 (56-111) OMEs for patients who underwent AVF superficialization, AVG, or BVT (long surgical incision procedure; P < 0.01) and consumed 0 (0-15) OMEs compared with 10 (0-43) OMEs, respectively (P = 0.07).

Regardless of preoperative opioid exposure, CKD patients undergoing vascular access surgery consumed fewer opioids than prescribed, with a median of <10% of opioids used. Therefore, we've reduced our institutional prescribing recommendations to 4 and 6 oxycodone 5mg pills for short and long surgical incision procedures, respectively.
