Implementation of a Quality Improvement Initiative to Decrease Opioid Prescribing in General Surgery

Background: There is increasing need to avoid excess opioid prescribing after surgery. We prospectively assessed overprescription in our hospital system and used these data to design a quality improvement intervention to reduce overprescription. Materials and methods: Beginning in January 2017, an e-mail-based survey to assess the quantity of opioids used postoperatively as well as patient-reported pain control was sent to all surgical patients in a 23-hospital system. In January 2018, as a quality improvement initiative, guidelines were given to surgeons based on patient consumption data. Prescription and consumption were then tracked prospectively. Wilcoxon signed-rank, analysis of variance, and Cuzick trend tests were used to assess for overprescription and changes over time in opioid prescribing and consumption. Results: We included 2239 patients in our cohort. The amount prescribed (median [IQR]: 30 [24-45] versus 18 [12-30], P < 0.001) and consumed (median [IQR]: 12 [7-20] versus 8 [3-15], P < 0.001) each decreased between the first and last quarter studied. Academic hospitals prescribed fewer opioids than nonacademic hospitals (median [IQR]: 24[15-40] versus median [IQR]: 30 [20-45], P < 0.001). There was no difference in the quantity of opioids consumed between patients treated at academic and nonacademic facilities (median [IQR]: 10[3-19] versus 10.5 [4-20], P = 0.08). Patients consumed a median of 42% of the opioids prescribed, and there was no significant trend in the percent consumed over time (P = 0.8). Conclusions: Patients used far fewer opioids than prescribed after common adult general surgery procedures. When surgeons were provided with patient consumption data, the number of opioids prescribed decreased significantly.
