BackgroundOver the past 2 decades, there has been an increase in opioid use and subsequently, opioid deaths. The amount of opioid prescribed to surgical patients has also increased. The aim of this systematic review was to determine postdischarge opioid consumption in surgical patients compared with the amount of opioid prescribed. Secondary outcomes included adequacy of pain control and disposal methods for unused opioids.ObjectiveThe objective of this study is to characterize postdischarge opioid consumption and prescription patterns in surgical patients.MethodsA systematic search in MEDLINE and EMBASE identified 11 patient survey studies reporting on postdischarge opioid use in 3525 surgical patients.ResultsThe studies reported on a variety of surgical operations, including abdominal surgery, orthopedic procedures, tooth extraction, and dermatologic procedures. The majority of patients consumed 15 pills or less postdischarge. The proportion of used opioids ranged from 5.6% to 59.1%, with an outlier of 90.1% in pediatric spinal fusion patients. Measured pain scores of those taking opioids ranged between 2 and 5 out of 10 and the majority of patients were satisfied with their pain control. Seventy percent of patients kept the excess opioids. Where planned disposal methods were reported, between 4% and 59% of patients planned proper disposal.ConclusionThis study suggests that surgical patients are using substantially less opioid than prescribed. There is a lack of awareness regarding proper disposal of leftover medication, leaving excess opioid that may be used inappropriately by the patient or others. Education for providers and clinical practice guidelines that provide guidance on prescription of outpatient of opioids are required.
