Background
 HIV rates in prisons & pre-trial detention are much higher than
in the community outside prisons
 Even where HIV rates remain low, HCV rates are high – often
exceeding 50%
 Very high co-infection rates (HCV co-infection observed in more
than 90% of HIV-positive prisoners in Genova)

Background: risk behaviours
Risk behaviours are prevalent in prisons
– Consensual & non consensual sex
– Injecting drug use
– Tattooing
– Sharing of razors and toothbrushes
5|
Firenze, 27 March 2011
Background: sexual activity
Difficult to obtain reliable data
– Methodological and ethical challenges
– Sex violates prison regulations
– Feelings of shame and homophobia: prisoners decline to participate
in studies
– Admitting to having been raped in prison goes against prisoner code
Nevertheless, evidence is clear: consensual and nonconsensual sex do occur

Firenze, 27 March 2011
Background: sexual activity
 Africa: (Nigeria, Zambia, Mozambique): 4-5.5%
 South America: 10% (Brazil)
 Asia: 20% (Thailand)
 Central & Eastern Europe:
– Russia (9.7-12%; much higher among long-term prisoners)
– Slovakia: 19% of female, 5.6% of adult male, 8.3% of juveniles
– Slovenia: 19.3%
– Hungary: 9%
– Armenia: 2.9% penetrative (36% against their will)
 Western Europe, Canada, Australia: 1-12% among males, up to 37% among females

Background: drug use in prisons
 Drugs can and do enter into prisons
 Many prisoners are in prison because of offences related to
drugs, and find a way to use inside
 Some discontinue using drugs in prisons
 Other prisoners start using (and/or injecting) drugs in prison
 No country has been able to stop drug use in prisons

What could happen – what we can prevent
•
Extensive HIV transmission can occur in prisons, significantly
contributing to the spread of HIV among the general population.
•
Thailand: HIV prevalence rate among injectors rose from a negligible
percentage to over 40% between Jan & Sept 2008, fuelled by
transmission of HIV in prisons.
•
Six studies among people who inject drugs in Thailand found that
imprisonment was associated significantly with HIV infection.

Firenze, 27 March 2011
What could happen – what we can prevent
•
Outbreaks of HIV in prisons have been documented in a number of
countries, incl Scotland, Australia, Lithuania, and Russia.
•
In Lithuania, in May 2002 the number of new HIV-positive test results
among prisoners found in a two-week period equalled all the cases of
HIV identified in the entire country during all of the previous years
combined.
•
284 prisoners (15% of the prison population) were diagnosed HIVpositive between May and August 2002.

Firenze, 27 March 2011
Prison conditions contribute to the problem
 Severe overcrowding
 Lack of work and meaningful activities
 Decaying physical infrastructure
 Lack of adequate medical care
 Lack of nutritious food & clean water
 Abuse & corruption
 Prisoner-on-prisoner violence

Public health implications
1. Health of prisoners = issue of public health concern
2. All people in Italy would benefit from enhancing the health of
prisoners and reducing the incidence of communicable
diseases
•

•
prisoners and their families
prison staff
the families outside prison
3. Communicable diseases transmitted in prison do not remain
there.

Interventions to address HIV in prisons
 We know what works – and what does not work:

Jürgens R, Ball A, Verster A. Interventions to reduce HIV
transmission related to injecting drug use in prison. Lancet Infect
Dis 2009; 9(1): 57-66
International expert & UN consensus since 1993:
HIV & HCV prevention & treatment in prisons are
essential, for public health & human rights
16 |
Firenze, 27 March 2011
Education and information
Information & education programs result in increased
knowledge (eg, Vaz, Gloyd & Trindade, 1996)
However, evidence of effect of increased knowledge
on behaviour is limited (Braithwaite, Hammett & Mayberry, 1996)
Peer education is more effective (Grinstead et al, 1999)
Education is not enough
17 |
Firenze, 27 March 2011
Prevention of sexual transmission
Providing condoms is feasible in prison settings
No security problems or other negative consequences
Prisoners use condoms when condoms are easily and
discreetly accessible - prisoners should never have to
ask for condoms or seen by others when they take a
condom

18 |
Firenze, 27 March 2011
Prevention of sexual transmission
Need for measures to combat rape and sexual abuse
– Changing the institutional culture tolerating sexual
violence
– Multi-pronged approaches are needed:
• Prevention efforts (prisoners education, classification, structural interventions
such as better lighting, better shower and sleeping arrangements)
• Staff training, investigation, prosecution, victim services
• Documenting incidents
Post Exposure Prophylaxis (PEP) should be available
19 |
Firenze, 27 March 2011
Needle and syringe programmes (NSPs)
 NSPs in the community exist in most countries, including Italy
 Studies have found NSPs
– to be effective in reducing HIV spread
– do not lead to increased drug use
 First established in prisons in Switzerland in 1992
 Since then, introduced in 12 countries in western and eastern
Europe and central Asia
20 |
Firenze, 27 March 2011
NSPs in prisons
 Today, NSPs are operating in a growing number of countries,
in all types of prisons and prison systems:
– In well funded prison systems (eg, Spain, Switzerland, Germany)
and severely under-funded prison systems (eg Moldova, Iran)
– In institutions with drastically different physical arrangements for the
housing of prisoners, from single cell to barracks
– In prisons of all security classifications and sizes
– In men’s and women’s institutions

Evidence NSPs
No negative consequences
– No increase in drug use or injecting
– needles are not used as weapons
Increased referral to drug dependence
treatment
Increased staff safety
24 |
Firenze, 27 March 2011
How is needle exchange done?
PNEPs utilize various methods for distributing injecting
equipment
– Hand-to-hand exchange by nurses and/or the prison
physician
– Distribution by one-for-one automated syringe dispensing
machine
– Distribution by prisoner trained as peer outreach workers
– Distribution by external NGOs or other health professional
who come into the prison for this purpose
25 |
Firenze, 27 March 2011
26 |
Firenze, 27 March 2011
Determinants of success
Prisoners must have confidential, easy access
Prisoners must have access to the type of
injecting equipment they want and need
Support of the prison administration, staff, and
prisoners is crucial (educational workshops for these
groups should be part of implementation of NSPs)
Start with pilot project in a few prisons, monitor
and evaluate, then scale up
27 |
Firenze, 27 March 2011
Recommendations NSPs in prisons
WHO,UNODC, UNAIDS recommend:
– Introduce NSPs urgently
– Provide easy and confidential access to NSPs
– Distribution through peers or NGOs
28 |
Firenze, 27 March 2011
Could providing NSP send out the wrong message?
 Could it be seen as “being soft” on drug use?
– As tolerating or condoning drug use in prisons?
– As giving up the fight against drugs in prisons?
 No: drug use remains illegal and measures to continue fighting
drugs in prisons continue
 But the fight against HIV is equally important
 Not taking evidence-based measures would mean condoning
the spread of HIV among prisoners and ultimately to the
community outside prisons
29 |
Firenze, 27 March 2011
How much do NSPs in prisons cost?
Very little – see Moldova example
Cost effective – every euro spent on prison NSP saves
many euros that would otherwise have to be spent on
treatment of infectious diseases
30 |
Firenze, 27 March 2011
Could providing bleach be enough?
Studies have shown that providing bleach in prisons for
decontamination purposes is feasible and does not
compromise security
But: Doubts about effectiveness
– Conditions in prisons reduce probability of effective
decontamination
→ Bleach programmes cannot replace NSPs
Provide information on limited effectiveness
Continue efforts to introduce NSPs
31 |
Firenze, 27 March 2011
Is providing NSPs enough?
NSPs are important component of efforts to reduce risk
of HIV through injecting
But alone they are not enough to eliminate the risk
Effective, evidence-based drug dependence treatment
is also needed, in particular methadone maintenance
treatment (MMT)
32 |
Firenze, 27 March 2011
Evidence: MMT in prisons
MMT is available in growing number of countries and is
most effective treatment for opioid dependence
– reduced used of opioids, reduced mortality, reduced HIV
risk behaviours, reduced criminal activity
MMT in prisons is feasible and effective
– most important benefit: reduced injecting drug use and
associated needle sharing, if correct dose & length of
treatment
33 |
Firenze, 27 March 2011
Evidence: MMT in prisons
Additional proven benefits of MMT in prison, for prison
systems, society, and prisoners:
–
–
–
–
facilitates entry and retention in post-release treatment
decreases re-incarceration
positive effect on institutional behaviour
helps reduce risk of overdose upon release
No negative side effects:
– no problems for security & no violent behaviour
– risk of diversion has been successfully addressed
34 |
Firenze, 27 March 2011
Recommendations: MMT in prisons
 WHO, UNODC & UNAIDS recommend:
– introduce and scale up MMT urgently in prisons
– ensure that those on MMT in the community can continue
MMT upon arrest and imprisonment
35 |
Firenze, 27 March 2011
NSP & MMT: Learning from Spain
 Spain introduced and scaled up both MMT and NSPs
 This has resulted in significant decreases in HIV and
HCV prevalence and incidence

Could we do sth else instead of NSP & MMT?
Other measures would not be as effective
Drug interdiction efforts are very costly
They only reduce, but do not completely eliminate drug
use in prisons
41 |
Firenze, 27 March 2011
Drug demand & supply reduction measures
Some systems have vastly expanded drug interdiction
measures (drug dogs, modern drug detection analysis, urinalysis,
“drug-free units”, etc)
Drug use has remained high
Improving documentation & evaluation of these
measures should be a priority
Prison systems with drug testing programs should
reconsider testing for cannabis
42 |
Firenze, 27 March 2011
HIV in prisons: other necessary steps
Pro-actively offer (and recommend) HIV and HCV
testing
Ensure uninterrupted treatment
Reduce overcrowding & improve prison conditions
Provide work & other meaningful activities for prisoners
43 |
Firenze, 27 March 2011
HIV in prisons: other necessary steps
 Provide non-custodial alternatives for people convicted of
offences directly related to their drug dependence (possession of
amounts for personal use or petty crimes committed to support drug use)
“Governments may … wish to review their penal admission
policies, particularly where drug abusers are concerned, in
the light of the AIDS epidemic and its impact on prisons.”
(WHO, 1987)
44 |
Firenze, 27 March 2011
Conclusion: From evidence to action
All prisoners have the right to receive … preventive measures
equivalent to [those] available in the community” (WHO, 1993)
 Time to move from evidence to action in Italy: access to
condoms, NSPs, MMT, voluntary HIV & HCV testing &
treatment, as part of comprehensive HIV & HCV strategy for
prisons and pre-trial detention, is urgently needed for prisoners
