"Participants were 21% female, 42% White, 29% African American, and 18% Latino. Most were homeless and reported living predominantly in the street (44%), temporary housing such as hotels or motels (15%), or shelters (14%). Significant increases were found in overdose knowledge, driven largely by increase in knowledge about the appropriate use of naloxone. Twenty-two participants witnessed and responded to 35 overdoses during the follow-up period. Twenty-six overdose victims were reported to have recovered, four died, and the outcome of five cases was unknown. The most commonly reported response techniques included: staying with the victim (85%), administering naloxone (80%), providing rescue breathing (66%), and calling emergency services (60%). The average number of appropriate response techniques used by participants increased significantly from baseline to follow-up (p<0.05). Half (53%) of programme participants reported that their drug use decreased at follow-up… Results suggest that overdose prevention and response training programmes may be associated with improvements in knowledge and overdose response behaviour among IDUs, with few adverse consequences and some unforeseen benefits, such as reductions in drug use.” (Wagner et al., 2010)
