ABSTRACT• Overprescribing of opioids may contribute to diversion and addiction• Evidence shows that patients undergoing elective day-surgery may receive more opioids than
necessary for post-operative pain management. 2,3,4
• We characterized surgeons’ post-operative opioid analgesia prescribing practices & patient experiences through a prospective study of patients undergoing elective ambulatory surgery.
METHODS
Study Design: • Prospective observational study • 18 different surgeons at BMC referred their patients for the study
Recruitment:• Participants screened & enrolled in-person at pre-operative appointments or via phone
Inclusion Criteria: • ≥18 years • Undergoing elective ambulatory surgery (Orthopedic, otolaryngology, general, podiatry,
maxillofacial, gynecology, and urology) Data Collection:• Patients surveyed in person or via phone week prior to & 7-10 days after planned surgery• Electronic Health Record used to confirm surgery date & type as well as opioid prescription
information
Demographics• 181 enrolled; complete follow-up data obtained from 149
participants (83% retention) • 53% female; mean age: 49 years
RESULTS
Figure 1: Participant Flow Diagram
RESULTS (CONTINUED)
Post-operative usage, refills, and storage:• Participants reported taking 42% of the pills prescribed over the 10-day post-
operative period (average 15 pills each)• 71% (94) of participants reported having leftover pills• 14% (18) of participants reported taking pills more often than prescribed • 10% (13) of participants reported seeking an early refill.
CONCLUSIONS
REFERENCES
• Most participants reported using substantially less post-operative opioid pain medication than prescribed.
• Over half of participants reported plans to retain unused medications after pain resolution.
• To reduce unnecessary opioid prescribing and potential availability for diversion and misuse, improved prescribing practices and disposal options are needed.
• Future studies may include an academic detailing component to review physician prescribing practices, provide individualized feedback support to help improve practices, pre-operative pain management patient counseling and provide patient support in initiating safe opioid use and disposal.
