The Middlesex-London Region Population 439,151 (2011 Census) –City of London: 366,151 –Remainder of Middlesex County: 73,000 SW Ontario along the Windsor-Quebec City corridor –Approximately 2 hour drive from Windsor and Toronto
5
What is the I-Track Survey? Survey of people who inject drugs developed and led by Public Health Agency of Canada (PHAC) –Behavioural and biological surveillance Occurs regularly at sentinel sites –Middlesex-London Health Unit participated for first time in 2012, during Phase 3 (2010-2012)
6
Why is I-Track Important? Injection drug use is an important risk factor in acquiring hepatitis C and HIV People who use injection drugs are a vulnerable population Middlesex-London had a significantly higher incidence of hepatitis C compared to Ontario –2010: 53.4 per 100,000 population vs. 33.1 per 100,000 in ON
7
METHODS
8
How were I-Track Survey Participants Interviewed? The Health Unit partnered with Regional HIV/AIDS Connection (RHAC) Face to face interview –Participants recruited and interviewed through RHAC needle and syringe exchange program (NEP) in January to February 2012 –Approximately 80 questions in 6 topic areas
9
Who Was Eligible to Participate? Had injected drugs in the past 6 months ≥ 16 years of age Able to provide informed consent Able to speak English or French Had not already participated in Phase 3 of the I-Track survey

Hepatitis C and HIV Prevalence Rates in I-Track vs. General Canadian Population
17
LIMITATIONS, SUMMARY AND LOCAL NEXT STEPS
18
Limitations Non-random convenience sample –Hard to reach population Self-reported –Leveraged existing relationships between interviewers and participants to minimize social desirability bias Other potential biases –Recall, selection
19
Summary Active local population of people who inject drugs with a high prevalence of hepatitis C and HIV Opioid drugs were most commonly injected Higher prevalence of injection risk behaviours compared to national sample
20
Local Next Steps Overview of local withdrawal management services and needle disposal and recovery –Assess NEP services in County area Additional reporting on impacts of drug use in Middlesex-London Collaborate with municipal and community partners to develop a comprehensive community drug strategy
