Guidelines for Patient-CenteredOpioid Prescribing and Optimal FDA-Compliant Disposal of Excess Pills after Inpatient Operation: Prospective Clinical Trial.

ABSTRACT

BACKGROUND: To optimize responsible opioid prescribing after inpatient operation, we implemented a clinical trial with the following objectives: prospectively validate patient-centered opioid prescription guidelines and increase the FDA-compliant disposal rate of leftover opioid pills to higher than currently reported rates of 20% to 30%. STUDY DESIGN: We prospectively enrolled 229 patients admitted for 48 hours or longer after elective general, colorectal, urologic, gynecologic, or thoracic operation. At discharge, patients received a prescription for both nonopioid analgesics and opioids based on their opioid usage the day before discharge if 0 oral morphine milligram equivalents (MME) were used, then five 5-mg oxycodone pill-equivalents were prescribed; if 1 to 29 MME were used, then fifteen 5-mg oxycodone pill-equivalents were prescribed; if 30 or more MME were used, then thirty 5-mg oxycodone pill-equivalents were prescribed. We considered patients' opioid pain medication needs to be satisfied if no opioid refills were obtained. To improve FDA-compliant disposal of leftover pills, we implemented patient education, convenient drop-box, reminder phone call, and questionnaire. RESULTS: Our opioid guideline satisfied 93% (213 of 229) of patients. Satisfaction was significantly higher in lower opioid usage groups (p = 0.001) 99% (99 of 100) in the 0 MME group, 90% (91 of 101) in the 1 to 29 MME group, and 82% (23 of 28) in the 30 or more MME group. Overall, 95% (217 of 229) of patients used nonopioid analgesics. Sixty percent (138 of 229) had leftover pills; 83% (114 of 138) disposed of them using an FDA-compliant method and 51% (58 of 114) used the convenient drop-box. Of 2,604 prescribed pills, only 187 (7%) were kept by patients. CONCLUSIONS: This clinical trial prospectively validated a patient-centered opioid discharge prescription guideline that satisfied 93% of patients. FDA-compliant disposal of excess pills was achieved in 83% of patients with easily actionable interventions.
