Notes: The reference group is no POE visit. Estimates are the multiplicative change in the outcome for total perioperative opioid consumption, hospital length of stay, and total multimodal perioperative analgesics. Estimates are Odds Ratios for perioperative complications, inpatient pain service, readmitted within 30 days, and withdrawal or relapse. ªData were log-transformed for normality.
