Introduction: Head and neck malignancy treatment often involves invasive surgeries, necessitating effective postoperative pain control. However, chronic reliance on opioid medications remains a challenge for many patients after surgery. Multimodal analgesia (MMA) within enhanced recovery after surgery protocols has shown success in limiting narcotic pain medications for other cancer types. In a prior study, MMA comprising acetaminophen, ketorolac, gabapentin, and a neurogenic block reduced opioid use in the 7‐day postoperative period for major head and neck reconstructive surgery. This study investigates the impact of multimodal analgesia on opioid prescription and pain during the 6‐week postoperative period for patients undergoing major head and neck oncologic surgeries, aiming to understand the longer‐term effects of narcotic use. Methods: The study retrospectively examined participants in a [hybrid type 1 effectiveness‐implementation pragmatic trial to assess multimodal analgesia's long‐term effectiveness in head and neck free flap surgery. Arm A received scheduled acetaminophen and as‐needed opioids, while Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the donor site, scheduled acetaminophen, and as‐needed opioids. Retrospective data collection included opioid prescription use and pain scores up to 6 weeks after surgery, gathered from the Kansas prescription drug monitoring program, K‐TRACS. Results: Thirty patients participated, 14 in Arm A and 16 in Arm B. The average morphine milligram equivalents per day of filled prescriptions were not significantly different between Arm A and Arm B (7.23 vs. 7.88, p =.845). Additionally, average pain scores at 6 weeks showed no significant difference between the two groups (1.4 vs. 1.9, p =.612). Conclusion: Patients with head and neck cancer treated with multimodal analgesia during the perioperative period did not exhibit significant differences in opioid use and pain within 6 weeks after discharge. To confirm these findings, a re‐examination with strict measures of opioid use and scheduled pain assessments in a prospective manner is warranted. Level of Evidence: 4. [ABSTRACT FROM AUTHOR]

Objectives: To optimize the delivery of multimodal analgesia to patients undergoing major head and neck oncologic surgeries. Methods: Pilot study included patients enrolled to receive either scheduled acetaminophen and as‐needed opioids (control group) or scheduled acetaminophen, gabapentin, ketorolac, and as‐needed opioids (experimental group). RCT, a hybrid type 1 effectiveness‐implementation pragmatic trial, was designed to test the effectiveness of the intervention. Arm A received scheduled acetaminophen and as‐needed opioids. Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the free tissue donor site, scheduled acetaminophen and as‐needed opioids. Results: Pilot: Thirty‐one patients undergoing major head and neck surgery were enrolled. Mean MMEs administered in control group (n = 15) was 251.60 mg (SD = 224.57 mg); mean MMEs in Experimental group (n = 16) was 195.78 mg (SD = 131.08 mg), p = 0.401. LOS was 8.0 days in control versus 7.0 days in experimental group (p = 0.054). RCT: Interim analysis for safety and futility was planned during trial's design after 30 patients (n = 14 Arm A, and n = 16 Arm B). Mean MMEs administered were 135.1 mg in Arm A, (SD = 86.0 mg) versus mean MME of 51.3 mg in Arm B (SD = 43.3 mg, (p < 0.05)). Given clear superiority results, the trial was prematurely terminated. Functional pain scores, LOS, and complications were similar between the arms (p > 0.05). Variability of mean MME was compared before and after implementation of the management protocols: SD in RCT#1 was 181.46 mg versus 124.6 mg in RCT#2. Conclusion: Multimodal analgesia significantly reduced the need for opioids in patients undergoing major head and neck surgery.
