Enhanced recovery after surgery protocol and postoperative opioid prescribing for cesarean delivery: an interrupted time series analysis

Abstract Introduction Enhanced recovery after surgery (ERAS) pathways have emerged as a promising strategy to reduce postoperative opioid use and decrease the risk of developing new persistent opioid use in surgical patients. However, the association between ERAS implementation and discharge opioid prescribing practices is unclear. Study design We conducted a retrospective observational quasi-experimental study of opioid-naïve patients aged 18+ undergoing cesarean delivery between February 2015 and December 2019 at a large academic center. An interrupted time series analysis (ITSA) was used to model the changes in pain medication prescribing associated with the implementation of ERAS to account for pre-existing temporal trends. Results Among the 1473 patients (out of 2249 total) who underwent cesarean delivery after ERAS implementation, 80.72% received a discharge opioid prescription vs. 95.36% at baseline. Pre-ERAS daily oral morphine equivalents (OME) on the discharge prescription decreased by 0.48 OME each month (p<0.01). There was a level shift of 35 more OME prescribed (p<0.01), followed by a monthly decrease of 1.4 OMEs per month after ERAS implementation (p<0.01). Among those who received a prescription, 61.35% received a total daily dose greater than 90 OME compared to 11.35% pre-implementation (p<0.01), while prescriptions with a total daily dose less than 50 OME decreased from 79.86 to 25.85% after ERAS implementation(p<0.01). Conclusion Although ERAS implementation reduced the overall proportion of patients receiving a discharge opioid prescription after cesarean delivery, for the subset of patients receiving an opioid prescription, ERAS implementation may have inadvertently increased the prescribing of daily doses greater than 90 OME. This finding highlights the importance of early and continued evaluation after new policies are implemented.

The Impact

Objective Opioid prescription after cesarean delivery is excessive and can lead to chronic opioid use disorder. We assessed the impact of an enhanced recovery after surgery (ERAS) pathway on inpatient opioid consumption after cesarean delivery. Study Design An ERAS pathway was implemented as a quality improvement initiative in December 2019. Preintervention (PRE) data were collected from March to May 2019 to assess baseline opioid consumption. Postintervention (POST) data were collected from January to March 2020. The primary outcome was inpatient postoperative opioid consumption in morphine milligram equivalents (MME). Secondary outcomes included the consumption of any opioids, postpartum length of stay, and opioid prescription at discharge. Results A total of 92 women were in the PRE group and 91 were in the POST group. Inpatient opioid consumption decreased by 87.3% from PRE to POST, from 124.7 (interquartile range [IQR]: 10–181.6) MME to 15.8 (IQR: 0–75) MME (p < 0.001). There was no difference in median postpartum length of stay (3.4 days PRE vs. 3.3 days POST; p = 0.12). The proportion of women who did not consume any opioids increased by 75.4% from PRE to POST (p = 0.02). The proportion of women discharged with an opioid prescription decreased by 25.6% from PRE to POST (p = 0.007), despite no formal change to prescribing practices. After adjustment for differences in race/ethnicity and gravidity, there was still a reduction in total inpatient opioid consumption (p < 0.001) and an increase in the proportion of women not consuming any opioids (adjusted relative risk (RR): 2.14, 95% confidence interval [CI]: 1.18–3.87), but the difference in rate of prescription of opioids at discharge was no longer statistically significant (adjusted RR: 0.70, 95% CI: 0.48–1.02). Conclusion Adoption of an ERAS pathway for cesarean delivery resulted in a marked reduction in inpatient opioid consumption. Such a pathway can be implemented across institutions and may be a powerful tool in combating the opioid epidemic. Key Points

Series Analysis

Abstract Purpose Prescription drug monitoring programs (PDMPs) have been established to combat the opioid epidemic, but there is no data on their efficacy in children. We hypothesized that a statewide PDMP mandate would be associated with fewer opioid prescriptions in pediatric surgical patients. Methods Patients < 18 undergoing inguinal hernia repair, orchiopexy, orchiectomy, appendectomy, or cholecystectomy at a tertiary children’s hospital were included. The primary outcome, discharge opioid prescription, was compared for 10 months pre-PDMP (n = 158) to 10 months post-PDMP (n = 228). Interrupted time series analysis was performed to determine the effect of the PDMP on opioid prescribing. Results Over the 20-month study period, there was an overall decrease in the rate of opioid prescriptions per month (− 3.6% change, p < 0.001). On interrupted time series analysis, PDMP implementation was not associated with a significant decrease in the monthly rate of opioid prescriptions (1.27% change post-PDMP, p = 0.4). However, PDMP implementation was associated with a reduction in opioid prescriptions of greater than 5 days’ supply (− 2.7% per month, p = 0.03). Conclusion Opioid prescriptions declined in pediatric surgical patients over the study time period. State-wide PDMP implementation was associated with a reduction in postoperative opioid prescriptions of more than 5 days’ duration.
