Hospital admission medication reconciliation in high-risk prescription opioid users.

Background: No studies have assessed the clinical significance of medication reconciliation in surgical patients using high-risk extended-release/long-acting (ER/LA) opioid medications.

Objectives: We assessed differences in the perioperative use of opioid analgesics in patients who underwent medication reconciliation upon hospital admission compared to patients who did not and identified predictors of perioperative use of opioids.

Methods: Retrospective observational quasi-experimental study including adult non-cancer patients who underwent elective surgery at UCSF Medical Center in the period January 2017 through December 2019 and received at least one opioid analgesic during surgical hospitalization.
