Root Cause Analysis of Adverse Events Involving Opioid Overdoses in the Veterans Health Administration

Abstract

ObjectiveThe Veterans Health Administration (VHA) serves a population with compounding risk factors for opioid misuse, including chronic pain, substance use disorders, and mental health conditions. The objective of this study was to analyze opioid-related adverse events and root causes to inform mitigation strategies associated with opioid prescribing and administration. MethodsThe researchers conducted a retrospective analysis of root cause analysis reports of opioid overdose events between August 1, 2012, and September 30, 2019. These adverse events were investigated locally by multidisciplinary hospital teams and reported by VHA facility patient safety managers to the National Center for Patient Safety for further aggregation and analysis. Type of event, location, and root causes were categorized. ResultsEighty-two adverse event reports were identified. Patients were primarily male with an average age of 61.4 years. Staff medication administration errors were the most common event type (57.3%), with most events resulting from process errors (65.9%) occurring in the health care setting (85.4%). Overall 36 events (43.9%) resulted in major or catastrophic harm. There were 172 root causes identified. The most common root causes were staff not following existing policy or lack of existing hospital policy on opioid management (18.0%); staff lacked training in areas such as managing the use or administration of opioids, correct use of opioid dispensing equipment, and recognition and proper response to an overdose (12.2%); and poor communication of opioid prescribing or administration during handoffs between clinical teams (11.6%). A lack of standardization in processes, training, and policies on opioid prescribing and screening, medication administration, equipment/pumps purchase and use, and contraband searches was a common theme throughout. ConclusionErrors in prescribing and administration of opioid medication can result in significant harm. A lack of standardized opioid administration practices and training, controlled substance policies, and interdisciplinary communication were frequent factors in adverse opioid events and should be a focus for future prevention.
