The NOpioid Project: a prospective observational feasibility study examining the implementation of a non-narcotic post-operative pain control regimen

Abstract

Background: Post-operative prescription of opioids has fueled an increase in opioid-associated morbidity and mortality. Alternative post-operative pain control with non-opioid pharmaceuticals can help counteract this effect. We investigated a non-opioid pain management protocol following emergent laparoscopic appendectomy and laparoscopic cholecystectomy.

Methods: Our tertiary referral center performed a prospective observational feasibility study of patients from October 2019 to 2020 who underwent emergent laparoscopic appendectomies and cholecystectomies. Patients aged 18-65 with no prior history of chronic pain or opioid abuse, no contraindications to taking acetaminophen and ibuprofen, and Glomerular Filtration Rate > 60 ml/min were included. Counseling was provided about non-narcotic pain control. Patients were not prescribed narcotics at discharge and were instead prescribed ibuprofen and acetaminophen. Patients were surveyed at their 2-week post-operative appointment to assess pain control and other patient-reported outcomes, including quality of life (QOL).

Results: Fifty-one patients met the inclusion criteria and completed the postoperative survey. Thirty-two were female (63%), average age 38, and BMI 30.4. 30 (59%) underwent laparoscopic appendectomy for acute non-perforated appendicitis and 21 (41%) underwent laparoscopic cholecystectomy for acute cholecystitis or symptomatic cholelithiasis. 88% of patients felt satisfied or neutral with their post-operative pain control at discharge. After 2 weeks, 34 patients (66.7%) rated QOL as high, 17 (33.3%) rated QOL as moderate, and none rated QOL as poor. Fascial suture was not associated with poor outcomes. Anxiety, depression, alcohol use, and prior abdominal surgery were not associated with increased need for post-operative narcotics. There were no significant differences between appendectomy and cholecystectomy in satisfaction with pain control or QOL (p > 0.05).

Conclusion: Patients undergoing surgery have an increased risk of developing an opioid disorder. The NOpioid Project demonstrated a non-narcotic multimodal pain regimen can be effectively adopted in the post-operative period after an emergent laparoscopic appendectomy or emergent laparoscopic cholecystectomy.
