2 Background 10 million prisoners - 3 million remandees in the world BUT 30 million individuals enter and leave prison - 90% male Prison populations grew by 25% in the last 15 years Drug dependence key factor in prison growth US popn up 13%, prison popn up 33%, PWIDs prisoners up 43%. 1/3 of 200,000 heroin users in US imprisoned annually 60% of PWIDs in a 12-city study been in prison. Re-incarceration rates very high for PWIDs In Australia, 84% of PWIDs inmates were re-incarcerated in 2 yrs of release versus 44% of all prisoners. They had a mean of 5 imprisonments.

3 Background HIV is a major health problem for prisons around the world. Prison settings have characteristics that increase HIV transmission. HIV, HBV, HCV, TB & mental illness more prevalent in prison High HIV infection and the over-representation of PWIDs in prisons combined risk behaviour create a critical public-health issue for prison authorities. Unless HIV is controlled in the prison setting it may not be controlled in broader community of some countries. Prison settings are a practical point of HIV prevention and treatment

4 Background Few clear documented cases of HIV transmission in prison Because it is difficult to gain access and the vast turnover of inmates HIV transmission does occur in prison, and can be extensive. HIV prevention programs for prisoners are rare Prisons are very expensive while HIV programs are not. the US prison system costs US$74 billion ($25,144 per inmate). the Australian prison system cost $2.4 billion ($50,874 per inmate). Hepatitis C and TB are very common in prison populations

5 Aim Systematic review of the HIV situation in prisons for all countries on A. Imprisonment rates B. HIV prevalence among male, female, PWIDs, MSM, sex workers and transgender prisoners, C. HIV transmission and incidence D. AIDS related mortality E. Provision of HIV programs The time period under observation was from January 2008 to April 2013.

6 Methods A multilingual (English, German, Spanish, Croatian, French, Arabic, Portuguese and Russian) desk review of the literature A survey of UN staff and experts List of Countries from Imprisonment rates from the International centre for prison studies

7 Results We identified 4,640 peer reviewed papers and 8,292 documents (see figure 1). Total included documents (N=261)

8 The Review Procedure Results of search in 238 Grey Literature Databases (N=8292) Results after title exclusion (N=611) Total included Grey Literature documents (N=128) Documents sent by UNODC officer (N=169) Results of exclusion due to irrelevant content or being out of date (N=92) Total included received files (N=77) Excluded articles on basis of title (N=3549), Abstracts (N=390), and unremoved duplicates (N=340) Total included documents (N=261) Full text exclusion (N=305) Total included peer-reviewed paper (N=56) Pee-reviewed literature (N=12570), Medline (N=5194), Web of Science (N=5001), Embase (N=2375) Results from duplicate removal in each database (N=6111), Medline (N=2045), Web of Science (N=2832), Embase (N=1234) Combination of search results and duplication removal (N=4640)

24 Evaluations of harm reduction in prison Positive evaluations have been documented for all programs Condoms decrease in unsafe sex OST decrease in injecting and sharing, trend to decrease HCV NSP decrease in injecting and sharing, no HIV/ HCV transmission HIV education improved knowledge

25 Recommendations Good prisoner health is good public health: High turnover of inmates mean diseases contracted inside leave prison. Start and continue ARV and TB treatment is essential to prevent HIV drug resistance and MDR-TB. Reduce prison populations: Provide OST also stops mortality. Divert drug offenders to treatment whenever possible. Provide NSP and condoms to reduce HIV transmission in prison. Prisoners have a legal right to medical treatment same level as in the community. Compassionate release from prison should be available to inmates in the final stages of AIDS.
