Summary

Mobile needle exchange programs, like the backpack model, effectively reach more frequent drug injectors, including Hispanic individuals. This approach improves access to sterile needles and referrals, crucial for preventing HIV and other blood-borne virus transmission.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Disease Prevention

Background:

  • Many people who inject drugs do not utilize existing needle and syringe exchange programs.
  • Barriers to access include operational issues, limited hours, inconvenient locations, and lack of transportation.
  • Improved access to sterile needles is vital for preventing human immunodeficiency virus (HIV) and other blood-borne virus transmission.

Purpose of the Study:

  • To evaluate a novel backpack needle exchange outreach model as a method to reach underserved populations of people who inject drugs.
  • To compare the characteristics of participants in a backpack needle exchange program with those using a fixed-site exchange.

Main Methods:

  • A backpack needle exchange outreach model was implemented in Providence, Rhode Island.
  • Participants completed surveys assessing demographics, drug injection frequency, and service utilization.
  • Data were compared between backpack exchange participants and clients of a traditional storefront needle exchange.

Main Results:

  • Backpack needle exchange participants were significantly more likely to be Hispanic compared to storefront exchange clients.
  • Individuals using the backpack exchange reported injecting drugs more frequently than those using the fixed site.
  • The backpack model demonstrated feasibility in reaching populations with limited access to traditional services.

Conclusions:

  • A backpack needle exchange is a feasible and effective strategy for providing sterile needles and referrals to hard-to-reach populations of people who inject drugs.
  • This mobile outreach model can help overcome barriers associated with fixed-site needle exchange programs.
  • Expanding access points, such as through mobile services, is important for comprehensive HIV and blood-borne virus prevention efforts.
