Dietze P, Crossin R, Scott D, et al. - The present study was conducted to evaluate the ways in which confirmed heroin overdose cases attended by ambulances are coded at dispatch to determine if incorrect coding of overdoses as cardiac arrests may limit the use of take-home naloxone. Between 2012 and 2018, researchers performed a retrospective analysis of coded ambulance clinical records collected in Victoria, Australia. Chi-square and Poisson regression were applied to examine data for quarterly counts, adjusting for age, gender, and patient GCS. Between 2012 and 2018, a total of 5,637 heroin overdose cases were attended (71.4% male, 36.4% aged under 35 years). This study’s findings revealed that almost half of the heroin overdoses were dispatched according to a protocol that would preclude the use of take-home naloxone prior to ambulance arrival and this changed little over the period in which take-home naloxone programs were operating in Victoria, Australia. The results considered that EMS should move as quickly as possible to newer versions of dispatch systems that enable the use of naloxone in cases of obvious opioid overdose that may be categorized as cardiac/respiratory arrest.
