After observing the effectiveness of Enhanced Recovery After Surgery (ERAS) protocols for gynecological surgery patients, an interdisciplinary team initiated a quality improvement project with an ERAS protocol to minimize opioid use of patients undergoing elective cesarean birth. Secondary outcomes during the three-month project included decreasing the patient's length of stay and inpatient care costs. We used the Lean Six Sigma methodology and measured aggregated patient outcomes of opioid use, length of hospital stay, and total cost. In addition, we incorporated the ERAS protocol into the electronic health record. Results showed a reduction use of morphine milligram equivalents of opioids, a slight decrease in length of hospital stay, and no change in the inpatient costs. The team recognized that implementation of an ERAS protocol is a best practice to reduce opioid use in patients undergoing a cesarean birth and decided to permanently include it in patient care processes.
