Empirical assessment of wounds among people who use substances

Abstract

BackgroundWounds are a significant source of morbidity among people who use substances (PWUS). This project sought to identify the incidence and severity of wounds among PWUS in the South Bronx, a region of New York City with one of the highest morbidities of substance use disorder. MethodsThis study recruited PWUS within the past 30 days. Research staff were trained to document the presence and severity of wounds. The primary outcome measure was the incidence of wounds. Acceptability of on-the-street wound care was assessed by the number of participants encountered. The association between participant characteristics and wounds was also evaluated. ResultsIn total, 586 PWUS were assessed (19.4 % female: 69 % Hispanic; 23 % Black; 5 % White). Heroin (65.7 %) and psychostimulants (58.3 %) were the most commonly used drugs. Approximately 23 % of outreach recipients disclosed a wound. Among those with a wound, 60.9 % reported one wound, 27.8 % had two wounds, and 11.3 % had three or more wounds. Small wounds (approximately the size of a cherry) were the most common (78.6 %). Recent use of stimulants or heroin, along with intravenous use of any substance were significantly associated with having a wound. ConclusionsThis study found that drug-related wounds were common among PWUS. Toxicology data from other sources indicate that xylazine was present in the NYC market at the time, though its prevalence among the current sample is difficult to determine. The occurrence and severity of substance-related wounds in NYC should continue to be monitored as a function of changes in the xylazine adulteration.
