Emergency Department Visits

ED Visits for Prescription Opioid Overdoses

According to OSHPD data, there was a total of 9,094 emergency department (ED) visits in LAC from 2005 to 2018 that listed prescription (Rx) opioid overdose as a diagnosis or external-cause-of-injury. Rx opioid overdose-related ED visits increased 54.3% from 490 in 2005 to 756 in 2018 (Figure 1).

About three-quarters (70%-78% from 2005-2018) of all Rx opioid overdose-related ED visits listed Rx opioid overdose as the principal diagnosis or principal external-cause-of-injury. Primary prescription (Rx) opioid overdose emergency department (ED) visits in LAC increased 54.3% from 372 in 2005 to 574 in 2018 (Figure 2). 

The rate of prescription opioid overdose ED visits were highest in the Antelope Valley region (SPA 1), followed by the West region (SPA 5) (Figures 3-4).
