1. Increased Use of Addiction Treatment

The SIF’s opening was associated independently with a 30% increase in detoxification service use, and this behaviour was associated with increased rates of long-term addiction treatment initiation and reduced injecting at the SIF.

2. Attendance and Detoxification

Reports that weekly use of Insite and any contact with the facility’s addictions counselor were both independently associated with more quicker entry into a detoxification program.

3. Syringe Sharing

Reports that Insite appears to have reduced syringe sharing.

Kerr T, Tyndall MW, Li K, Montaner JS, Wood E. 2005. Safer Injecting Facility Use and Syringe Sharing Among Injection Drug Users. Lancet 366:316-8

4. Impact on Drug-Use Patterns

Reports that the opening of Insite did not adversely affect community drug use, including relapse into injected drug use, stopping injected drug use, and seeking treatment. Insite appears to have improved public order and reduced syringe sharing.

6. Attendance, drug use patterns, and referrals

Reports that Insite has successfully been integrated into the community, has attracted a wide cross section of community injection drug users, has intervened in overdoses and initiated over 2000 referrals to counseling and other support services.

7. Evaluation Methodology

Lays out the method by which the health and community impacts of Insite will be measured and evaluated.

8. Rationale for Evaluation

Outlines the rationale for evaluating Insite and reasons that if the Insite study is able to show public-health and/or community benefits it may provide a public-health model with the potential to address many of these drug-related harms that plague many North American cities.

9. Changes in Public Order

Reports that the opening of Insite appears to have lead to improvements in public order, including reduced public injection drug use and public syringe disposal.

10. Impact on Drug Related Crime

Examines crime rates in the neighborhood surrounding Insite during the year before versus the year after Insite opened. It finds no increases in drug trafficking or assaults/robbery, and a decline in vehicle break-ins/vehicle theft.

Wood E, Tyndall MW, Lai C, Montaner JSG, Kerr T. 2006a. Impact of a Medically Supervised Safer Injecting Facility on Drug Dealing and Other Drug- Related Crime. Substance Abuse Treatment, Prevention and Policy 1:1-4

11. Attraction of Higher-Risk Injection Users

Reports that Insite attracted injection drug users (IDUs) with elevated risks of blood-borne disease infection and overdose, and IDUs who were contributing to public drug use and unsafe syringe disposal problems stemming from public injection drug use.

Wood E, Tyndall MW, Li K, Lloyd-Smith E, Small W, et al. 2005a. Do Supervised Injecting Facilities Attract Higher-Risk Injection Drug Users? American Journal of Preventive Medicine 29:126-30

12. Service Uptake

Reports that

  • Insite has been well accepted among injection drug users in the community.
  • Homelessness, a common factor in public injection drug use, is associated with frequent use of Insite
  • Daily safe injection facility use is associated with several risk behaviors that have been linked to elevated rates of HIV transmission in this community, including frequent cocaine injection.

13. Syringe Sharing Factors

Reports that the use of Insite by injection drug users is associated with reduced syringe sharing.

Wood E, Tyndall MW, Stoltz J, Small W, Lloyd-Smith E, et al. 2005b. Factors Associated with Syringe Sharing Among Users of a Medically Supervised Injecting Facility. American Journal of Infectious Diseases 1:50-4

14. HIV Education

Reports that individuals requiring help injecting – a risk factor previously associated with HIV incidence – are receiving safer injecting education at Insite.

Wood E, Tyndall MW, Stoltz J, Small W, Zhang R, et al. 2005c. Safer Injecting Education for HIV Prevention Within a Medically Supervised Safer Injecting Facility. International Journal of Drug Policy 16:281-4

15. Preventing Overdose Deaths

Reports that there have been a large number of overdoses within the SIF, and that none of these overdoses resulted in a fatality. These findings suggest that SIF can play a role in managing overdoses.

16. Preventing HIV/AIDS

The purpose of this analysis is to measure the prevalence and correlates of baseline HIV among those who are using the SIF, to determine if InSite could be used as a site for HIV related care and treatment.

17. Reducing Harms Associated With Drug-Related Overdose

Conventional drug overdose prevention strategies have been criticised for failing to address the macro- and micro-environmental factors that shape drug injecting practices and compromise individual ability to reduce the risks associated with drug-related overdose.Safer injection facilities (SIFs) constitute one such intervention, although little is known about the impact of such facilities on factors that mediate risk for overdose.

Thomas Kerr, Will Small, David Moore, Evan Wood, 2006. A micro-environmental intervention to reduce the harms associated with drug-related overdose: Evidence from the evaluation of Vancouver’s safer injection facility. International Journal of Drug Policy

18. Changing Injecting Practices

Consistent SIF use was compared with inconsistent use on a number of self-reported changes in injecting practice variables.More consistent SIF use is associated with positive changes in injecting practices, including less reuse of syringes, use of sterile water, swabbing injection sites, cooking/filtering drugs, less rushed injections, safe syringe disposal and less public injecting.

19. SIS Evaluation Review

In many cities, infectious disease and overdose epidemics are occurring among illicit injection drug users. Vancouver’s safer injecting facility has been associated with an array of community and public health benefits without evidence of adverse impacts. These findings should be useful to other cities considering supervised injecting facilities and to governments considering regulating their use.

20. Drug Users' Perceptions Regarding InSite

This study was undertaken to explore injection drug users' experiences and opinions regarding North America's first SIF in Vancouver, Canada.

21. Limiting Hepatitis C Infection

The SIF has attracted injection drug users with a high burden of HCV infection and a substantial proportion of uninfected individuals. Although crosssectional, this study provides some insight into historical risks for HCV infection among this population, and prospective follow-up of this cohort will be useful to determine if use of the SIF is associated with reduced risk behaviour and HCV incidence.
