INTRODUCTION: This study aimed to analyze opioid prescribing behavior following surgical interventions for benign prostatic hyperplasia (BPH), focusing on differences in postoperative opioid prescribing practices between patients who undergo surgical procedures in operative room (OR) settings vs. non-operative room (non-OR) settings. METHODS: A retrospective cohort study was conducted using a 10% random sample of the IQVIA PharMetrics RESULTS: Among the included men (n=6022), those undergoing procedures in OR settings were more likely to receive opioid prescriptions postoperatively compared to those in non-OR settings (42.78% vs. 28.00%, p<
0.002). While cumulative days and MEDD of opioid prescriptions did not significantly differ between groups, there was a statistically significant difference in the distribution of opioid receipt duration (p=0.0128). The adjusted model showed significantly higher odds of opioid prescription for men undergoing OR procedures (odds ratio 1.922, 95% confidence interval 1.690-2.185). CONCLUSIONS: Men undergoing BPH surgeries in OR settings were more likely to receive opioid prescriptions postoperatively, suggesting potential overprescription. Despite similar cumulative opioid use, differences in prescription rates indicate a need for improved postoperative pain management strategies, possibly using non-opioid alternatives. Future research should focus on optimizing pain control, characterizing actual opioid consumption, and considering patient-specific factors in surgical decision-making.
