Research Note: Factors Associated with Skin Cleaning Prior to Injection among Drug Users

Injection drug users are at risk for a variety of infections when hygienic injection practices are not performed. Disinfecting the injection site prior to injecting reduces the risk of bacterial infections but has been overlooked in many prevention efforts. Using what is known about factors associated with risk-reduction behaviors of disinfecting equipment, we evaluated a model to determine whether those factors are associated with disinfection of the injection site. Sociodemographic and behavioral data were collected in interviews with 600 injection drug users. The majority of injection drug users do not clean the injection site prior to injecting. Results indicate that gender, ethnicity, and frequency of injection were significantly related to whether or not an injector cleaned the injection site. Failure to clean the injection site prior to injecting is a common practice and constitutes a health risk among injection drug users, particularly in a population prone to other infections. Prevention efforts need to incorporate all levels of sterilization procedures when working with these high risk populations.
