Objective: To examine our outpatient urologic surgery cohort for trends in opioid consumption, given the lack of consensus on opioid prescription after outpatient urologic procedures. While opioids have a role in multimodal postoperative analgesia, there is emerging data that they may not be routinely required after pediatric surgery.
Methods: Data on opioid use was prospectively collected over 16 months via postoperative telephone calls to caregivers of patients undergoing outpatient urologic surgery. Patient characteristics, surgery type, analgesia, and opioid prescription and usage information were recorded. Patients were prescribed as needed oxycodone and scheduled acetaminophen and ibuprofen for 48 hours, then as needed. The relationships between the log mean of the number of opioid doses used and age, type of surgery, race, and opioid prescription were modelled using negative binomial regression with the robust standard errors.
Results: Two hundred sixty-five patients were included. They were predominantly male with median age 2.6 years. The mean number of opioid doses prescribed per patient was 5.8 (SD 2.8, range 3-20). Over half of patients used no opioids, and mean opioid use was one dose. Those prescribed >5 doses took on average 3.4 times more doses compared to those prescribed >5 (P = .0003), and this was the only factor significantly associated with the amount of opioid used.
Conclusion: Our findings suggest that opioids are over-prescribed after outpatient pediatric urologic surgery, with 95% of patients having leftover medication and 54% not using any opioids at all. While opioid requirements were low across all sub-cohorts, patients who were prescribed more opioid doses used significantly more doses.
