Implementation of an Evidence-Based Protocol Significantly Reduces Opioid Prescribing After Ventral Hernia Repair.

BACKGROUND: Increased recognition of the dangers of opioid analgesia has led to significant focus on strategies for reducing use through multimodal analgesia, enhanced recovery protocols, and standardized guidelines for prescribing. Our institution implemented a standard protocol for prescribing analgesics at discharge after ventral hernia repair (VHR). We hypothesize that this strategy significantly reduces opioid use.

METHODS: A standardized protocol for discharge prescribing was implemented in March 2018. Patients were prescribed ibuprofen, acetaminophen, and opioids based on milligram morphine equivalent (MME) use the 24 hours prior to discharge. We retrospectively reviewed prescriptions of opioids for two 6-month periods-July-December 2017 (PRE) and July-December 2018 (POST)-for comparison using EPIC report and the South Carolina Prescription Monitoring Program. Analysis performed included Mann-Kendall linear trend test and Student's t -test for continuous variables.

RESULTS: VHR was performed in 105 patients in the PRE and 75 patients in the POST group. Total MME prescribed decreased significantly from mean 322.7 + 261.3/median 225 (IQR 150-400) MME to 141.6 + 150.4/median 100 (50-184) MME ( P < .001). This represents a 57% reduction in mean opioid MME prescriptions. Acetaminophen prescribing increased from 10% to 65%, and ibuprofen from 7.6% to 61.3%. Refills were prescribed in 21 patients (20%) during the PRE period, which decreased to 10.7% during the POST group ( P = .141). Implementation of an evidence-based protocol significantly reduces opioid prescribing after VHR.

DISCUSSION: A multimodal approach to postoperative pain management decreases the need for opioids. The additional implementation of an evidence-based prescribing protocol results in significant reduction of opioid use following VHR.
