Brief summary

This is a pilot single site randomized controlled trial to assess the feasibility and acceptability of a nudging intervention providing surgeons with procedure-specific feedback regarding patients' postoperative opioid prescription-to-consumption ratio in individuals 18 years of age and older.

Detailed description

The trial will randomize surgeons to either intervention (direct feedback) or control (no direct feedback) arms. Surgeons who frequently performing specific elective general, gynecologic, orthopedic, and neurologic surgeries at Vanderbilt University Medical Center will be identified during a 30-day study lead-in period. Then, patients aged at least 18 years undergoing these surgeries at VUMC during study days 1-60 will be contacted by telephone 14 days postoperatively (study days 15-74) and asked to perform an opioid pill count; they will also be asked about opioid refills, satisfaction with analgesia, emergency room visits or hospitalizations for pain, and opioid misuse. The electronic medical record will be also queried for the size of the initial postoperative opioid prescription as well as evidence of any refills for each enrolled subject. Following the first block of surgeries and associated patient follow-up (study days 1-74), data will be analyzed and then surgeons will be randomized in a 1:1 ratio to the intervention or control arms. Randomization will be stratified by both surgical specialty and by mean opioid prescription size during the initial block of surgeries. After study day 97, surgeons in the intervention arm will be provided procedure-specific direct feedback on opioid prescribing and consumption for their patients who had surgery during days 1-60. After this intervention, the trial will assess pre-post change in opioid prescription size (measured in oral morphine equivalents) from baseline between the two groups for surgeries performed during days 108-167.

Interventions

BEHAVIORALDirect Feedback

Procedure-specific direct feedback will be provided to surgeon participants through electronic and written communication, on patients' opioid consumption-to-prescription ratio. Surgeon participants who perform more than 1 of the specified procedures will receive nudging communications for each individual procedure.

Recruitment details

Surgeon recruitment began on 12/01/2022 and ended on 12/31/2022. Patient recruitment for Phase 1 began on 1/15/2023 and continued through 3/15/2023. Phase 2 recruitment began on 5/22/2023 and ended on 6/30/2023.

Pre-assignment details

94 surgeons were identified as potential participants in the study. 27 did not meet eligibility criteria. 20 did not agree to participate. 47 were consented and enrolled into the study. 12 surgeons met criteria to be randomized following Phase 1 Patient Recruitment period. Patients who underwent surgery performed by a surgeon who received the nudge intervention were patients who were analyzed only for safety and were not included in other groups. There was a waiver of consent for this group.
