Surveillance for Opioid Overdose in the Veterans Health Administration, 2004-2014

Drug poisoning, or overdose, is an epidemic problem in the United States1,2. In keeping with national trends, a recent study combining U.S. Veterans Health Administration (VHA) data with the National Death Index showed increases in opioid overdose mortality from 2001 to 20093. One of the challenges in monitoring the overdose epidemic is that collecting cohort data to analyze overdose rates can be laborintensive. Moreover, analysts are often unable to collect real-time data on overdose events.

Using NC DETECT for Comprehensive Morbidity Surveillance on Poisoning and Overdose

A retrospective analysis of emergency department data in NC for drug and opioid overdoses has been explained previously [1]. We built on this initial work to develop new poisoning and surveillance reports to facilitate near real time surveillance by health department and hospital users. In North Carolina, the availability for mortality and hospital discharge data are approximately one and two years after the event date, respectively.

Opioid Diagnosis Codes - Adapted from the HCUP Definition - Kansas Department of Health and Environment

This syndrome was created as a way to integrate the H-CUP Opioid-Related Hospital Use definition into ESSENCE. H-CUP is the Healthcare Cost and Utilization Project and we believe their Opioid-Related Hospital Use definition is a great starting point for developing opiate-use syndrome definitions.

CDC Opioid v1

States currently funded by CDC’s Enhanced State Opioid Overdose Surveillance (ESOOS) program have been asked to monitor opioid overdose trends in their states. In collaboration with our ESOOS partners, CDC staff developed some lessons learned in querying opioid overdose ED visits in syndromic surveillance systems. Based on this preliminary work, CDC developed an opioid overdose syndrome definition that captured all of the lessons learned from ESOOS states.

CDC All Drug v1

Purpose: States currently funded by CDC’s Enhanced State Opioid Overdose Surveillance (ESOOS) program have been monitoring drug overdose trends in their states. Because CDC had worked with these states to develop syndrome definitions for stimulant, heroin and opioid overdose, they decided to also develop a syndrome definition for all drug overdose.
