Implementation of a Post-Surgical, Multimodal Analgesia Pain Management Order Set in Opioid-Naive Patients.

Background: Perioperative pain management guidelines recommend using multimodal analgesia to improve pain control while reducing opioids administered. The primary objective of this study was to assess whether implementing multimodal analgesia on general surgery postoperative pain management order sets would reduce opioid quantities postoperatively.

Methods: Opioid-naive patients undergoing nonemergent general surgery procedures were evaluated before and after order set revision. The primary outcome was the total quantity of inpatient opioids administered. The secondary outcomes were inpatient naloxone administration, patient-reported pain scores, and opioid quantities prescribed at discharge.

Results: The average daily opioid consumption was less each postoperative day (POD) after implementing the revised postsurgical multimodal analgesia pain management order set. On POD 1 and POD 2, average opioid consumption was 53.6 and 47.9 oral morphine equivalents (OME) before the multimodal analgesia order set, respectively, compared with 21.2 and 21.4 OME after, respectively (p < 0.01 and p < 0.01, respectively). Average daily opioid consumption through POD 3 was 60.6 OME before and 21.14 OME after the revision. Average daily pain scores were similar on POD 0, 1, and 2 before and after (3.2, 2.8, and 2.4 compared with 2.8, 3.1, and 2.7, respectively; p = 0.09, 0.33, and 0.12, respectively). On POD 3, pain scores were higher in the postorder set group (2.8 compared with 1.9; p < 0.01), but this was considered clinically insignificant. Average daily pain score through POD 3 was 2.6 before implementation compared with 2.8 after implementation. Neither group required naloxone administration.

Conclusion: Using perioperative multimodal analgesia reduces opioid consumption without increasing pain scores.
