Background

• Ukraine is home to Europe’s worst HIV epidemic (prevalence >1%). Among 290,000 people who inject drugs (PWID) prevalence 21.5-41.8%1,2

• Incarceration rate in Ukraine = 350 / 100,000 population3 or ~110,000 people

Background

• Globally, within-prison drug injection common (3-53%)1

• In Ukraine, despite high rates of HIV and large PWID population in prison, opioid substitution therapy (OST) and needle and syringe exchange programs (NSP) are not available in prison settings

• In general: less injection in prison, but more needle/syringe sharing2

• Relatively few studies in low- and middle-income countries

• Lack of studies examining only HIV-infected inmates (the only individuals who can transmit HIV)

Study aim

To describe both the prevalence and key correlates of within-prison drug injection and

injection equipment sharing among HIV-infected individuals recently released from prison

in Ukraine.

Page 8: Prevalence and Correlates of an Extremely High Risk Behavior

Methods

• Recruitment• Kiev (N=47) – prison-release social services agency• Odessa (N=50) – modified snowball sampling

• Eligibility criteria• HIV+• Released from prison 1 to 12 months (mean=5.8) prior

• 60-minute cross-sectional interviews • Pre-, within- and post-release time periods covered• Demographics and criminal justice history• Substance use disorder screening• Drug use and injection history• Use of OST and antiretroviral therapy (ART)

Page 9: Prevalence and Correlates of an Extremely High Risk Behavior

Methods (continued)

• Dependent variables:• Within-prison drug injection (WP-DI)• Within-prison sharing of injection equipment

• Data analysis:• N=95 (2 excluded because dependent variable not

answered)• Bivariate modeling of basic characteristics with WP-DI

and injection equipment sharing• Multivariate logistic regression for modeling correlates of

both dependent variables

Key findings summarized

• More than half reported within-prison drug injection• About three quarters of this group shared needles or syringes

in prison, with a mean of 4.43 users per / needle• Prison term length not correlated with injection

• Correlates of within-prison drug injection• Pre-prison opioid use• Site of recruitment (Kyiv)• Gender (Male)

• Correlates of within-prison injection equipment sharing• Pre-prison opioid use• Site of recruitment (Kyiv)

Page 17: Prevalence and Correlates of an Extremely High Risk Behavior

Implications

• Prison-based OST and NSP are evidence-based practices that reduce within-prison drug injection and equipment sharing.1,2

OST, NSP urgent need to implement and scale

HIV testing and treatment must ensure availability within prison settings

• Need for effective transitional programs for those returning to the community OST and ART linkage
