Opioid overdose deaths continue to be an increasing problem throughout the United States and within Utah. 1 Utah is the eighth highest drug overdose mortality rate in the United States (16.9 per 100,000) Some of the risk factors for overdoses have been delineated. 3,4 1.Prescription Drug Abuse: Strategies to Stop the Epidemic.

The veteran population has nearly twice the rate of fatal accidental poisoning compared with adults in the general US population Opioid medications and cocaine were frequently mentioned as the agents causing poisoning on death records More detailed information about veterans experiencing overdose would help to tailor preventative efforts in this population. 1.ASB Bohnert, et. al Accidental Poisoning Mortality Among Patients in the Department of Veterans Affairs Health System.

To describe veterans who received naloxone rescue therapy for opioid overdose and identify risk factors within this population such as: Demographic information Diagnoses Prescription accessibility of opioids and benzodiazepines on the day of and within 120 days of naloxone rescue therapy Urine drug screen results within 120 days of naloxone recue therapy
Data collection Extracted from the VA Data Warehouse Retrospective open chart review Reviewed veterans who received naloxone rescue therapy at the SLC VAMC emergency department (ED) for opioid overdose between 1/1/2009 and 1/1/2013 Tabulations were made using Microsoft® Excel
Information collected: Naloxone rescue therapy (ED visit date) Demographic information Diagnoses Sleep apnea, sleep disorders, obesity, cardiac disease, pulmonary disease, mental health diagnoses, and/or substance use disorder Prescriptions accessibility within 120 days and on the day of the ED visit: Morphine equivalents daily (MED) Lorazepam equivalents daily (LED) Urine drug screen (UDS) results Visits stratified by accessibility to: Opioids (OPs) only Benzodiazepines (BZs) only OPs & BZs No OPs or BZs Non-VA documented prescriptions only Day of naloxone therapy Within 120 days prior to naloxone therapy

Demographic Information The average age in our sample was 62, which is consistent with literature regarding age risk factors. Prescribed Medications The ED visit date was not immediately proximate to the last OP prescription pick-up date VA’s current opioid safety guidelines 6 target > 200mg MED as the “high risk” dose but this would not capture most of the veterans in the OP only group. Veterans prescribed OPs & BZs concomitantly constitutes 23% of those who required naloxone rescue therapy. VHA Memorandum April 2, 2014.
Comorbidities Cardiovascular diagnoses and psychiatric disorders were more prevalent than SUD, which is not consistent with previously published risk factor literature. Urine Drug Screens 68% of veterans prescribed OPs and/or BZs had no documented UDSs within 120 days prior to the ED visit date 58% of the UDSs were not reflective of prescribed regimens which may indicate many veterans have aberrant behaviors which are associated with overdose risk VHA Memorandum April 2, 2014.
