Introduction: Syringe exchange programs (SEPs) have been shown to reduce HIV incidence among active drug injectors on a populational level. Their impact on an individual level may depend on SEP retention and adherence to sterile injection practices, and individual variability in these may explain observed differences in SEPs' effectiveness - yet individual level patterns of SEP use are poorly characterized. Methods: Review of transaction records of a NYC SEP. Results: For the period 1993-1999, 18,421 individuals received syringes. Among those for whom demographics were available (11,252) 29% were female; 17% were Black, 23% Hispanic, 59% White. 45% used the SEP once, 13% twice, 24% 3-10 times, and 18% >10 times. Among 13,001 who used the exchange once, twice, 3-10 times, and >10 times, the mean ages were 23, 25, 28 and 32 years respectively (p<.0001). During 1993-96, 62% (4,903/7,921) came to the SEP ³3 times: 42% and 30% were still using the SEP six and twelve months later, respectively. Conclusion: A proportion of individuals come once to the SEP without becoming engaged in SEP use. While a plurality are engaged for periods of 6-12 months, there is significant variability in the frequency and patterns of SEP attendance with utilization increasing with age. A greater understanding of the individual level variability in SEP use is needed to develop means of enhancing the potential benefit to individuals and to account for observed program variability.
Learning Objectives: At the conclusion of the session, the participant in this session will be able to: 1. develop a greater understanding of the variability in individual patterns of syringe exchange program use, 2. understand the degree to which individuals are longitudinally engaged in syringe exchange program use, 3. understand how differences in individual patterns of syringe exchange use may in part account for observed differences in SEP effectiveness, and consequently, in the effectiveness of HIV risk reduction
