Problem drug use, HIV and injecting: an overview of the European experience Paul Griffiths, EMCDDA Drug Control in the Baltic Region, Vilnius, 27 September 2005
Outline of this presentation • The EMCDDA • structure • working methods • Overview of available European data on • problem drug use, • on responses to problem drug use • making special reference to injecting and HIV • A few thoughts on: • future face of problem drug use in Europe • what are some key information needs and deficits
European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) • The Central reference point for drug information in the EU • Established in 1993, based in Lisbon, Portugal • A decentralised agency of the European Union • a response to the need to cope with new tasks of a technical and/or scientific nature • agencies of particular relevance to public health; • EMCDDA – European Monitoring Center for Drugs and Drug Addiction, Lisbon (Portugal) • EMEA – European Medicines Agency, London (United Kingdom) • ECDC – European Centre for Disease Prevention and Control, Solna (Sweden)
Overview of our data collection approach • Network of national focal points in MS (REITOX ) • Annual reporting • National overview • Standard tables • Structured questionnaires • Expert groups per indicator area that meet annually • Liaison with other specialist information providers • Emphasis on encouraging adoption of common methods & in providing European level added value
EMCDDA – membership • Membership pre-2004 – the 15 EU Member States • Norway started providing data in 2001 (15+1) • May 2004, enlargement – 10 new members • Cyprus, Czech Republic, Estonia, Latvia, Lithuania, Hungary, Malta, Poland, Slovenia, Slovakia. • Candidate countries – Bulgaria, Romania and Turkey • Important to note that in some areas the new countries change… • analysis of the European situation • analysis of data availability
HIV and the European picture • HIV has to a large extent been one of the major issues to shape modern European drug policy • Inextricably linked with epidemic of injecting heroin use that Europe experienced over the 1990s • Stimulated investment in new methods to assess problem drug use and risk behaviours • Profoundly altered the way services were structured and orientated…. more proactive, broader set outcome objectives
The European picture is a heterogeneous onebut with some common elements • Diversity exists in respect to HIV among IDUs • Estimates of between 850,000 and 1.3 million IDUs in EU 25 • Some countries have had only small outbreaks of HIV infection and have managed to maintain very low prevalence rates • Some countries have had major epidemics ….but the overall picture now appears stable or falling in most countries • Diversity of responses • Balance of prevention, treatment and harm reduction interventions • Scale of responses & timing of responses • No simple relationship between policy and the situation • Common elements • Although major differences remain in emphasis EU members states appear now to operate within a broad policy consensus • Cautious optimism about stable or an improving situation in respect to drug injecting, HIV infections among IDUs and heroin consumption in many MS
Data sources on HIV-AIDS in IDU • Reporting from routine surveillance and HIV/AIDS case reporting (EuroHIV) • Data from EMCDDA drug related infectious disease indicator (IFD) • routine testing at drug treatment centres • studies of IDU (in and out of treatment) • Neither source provides comprehensive coverage or easily allows the monitoring of trends over time • Data set is improving
Data sources on HIV-AIDS in IDU • Routine surveillance suggests IDU no longer the main route of transmission for AIDS …but how do we interpret this? • Data weaker from routine disease surveillance for HIV prevalence in IDUs • IFD indicator suggests large differences in HIV prevalence between countries and large differences between different populations within countries
HIV prevalence among IDUs in the EU EMCDDA 2004Notes: Colour indicates midpointsLocal data shown in ()
HIV seroprevalence and diagnostic testing studies of IDUs (treatment & non treatment)
HIV in IDUs in Europe • Marked difference between countries and within some countries • High prevalence countries (old MS) Italy, Spain, Portugal, followed by France • Some high prevalence estimates from new MS (Latvia, Estonia), and worries about others (Poland) • Low prevalence countries in both old and new MS including countries with high prevalence IDU • Cautious assessment is the long term trend appears to be stable or downwards • Some small increases in recent data in some countries or in specific subpopulations • Data quality problems so analysis must be made with caution
A note on HCV prevalence in IDUs • Prevalence estimates higher and more convergent than for HIV • Clear need to finding effective prevention strategies • Routine disease surveillance sources of limited value • Drug injecting principle route of transmission for HCV in Europe
What is happening to heroin use and injecting heroin use ? • Data from… • Problem drug use indicator • Treatment demand indicator (TDI) • Drug related deaths indicator… • major cause death among young males in Europe • and among IDUs the major cause mortality • e.g. 2001 EU15 reported… 8,347 DRD as compared to 1,633 AIDS deaths among IDUs
Prevalence of problem drug use (indicator) • Operational definition PDU: “injecting, long-term or regular use of opiates, cocaine and/or amphetamines • Estimates 1.2 and 2.1 million PDUs in EU 25 • Historically mainly reflected heroin use and injecting • Amphetamines in some countries (mainly Nordic countries) • Growing heroin smoking population (from late 1980s) • Prevalence estimates produced from different sources and methods, both national and local studies (CRC, multipliers, synthetic estimation techniques) • Recently some limited work on incidence modelling mostly based on statistical inference from treatment populations • Estimates more often local. Getting national coverage more difficult • IDU estimates are particularly lacking

General observations PDU • Mixed picture in terms PDU estimates • But indicators suggest a peak of PDU in early 1990s in most countries with a stabilisation thereafter. • Injecting appears a less popular mode administration in many countries and most new heroin users to treatment are non injectors • DRD most countries getting old and trending down • Suggesting new recruitment into drug injecting and heroin use may be down • The picture looks different for some of the NMS
Overview Responses • Data collection is less well developed in this area • Treatment data is limited • substitution treatment • specialist centres • underestimate • Increase in treatment especially substitution treatment in most EU MS • Also an Increase in some harm/risk reduction interventions, particularly NSE

Conclusions • Data in this area are often heterogeneous and should be interpreted with caution • nonetheless data availability and quality have improved considerably • It is possible to provide some better understanding of drug use and HIV in Europe and to identify trends • Large differences between countries: PDU/IDU, HIV/HCV, and in the services available • The face of problem drug use in Europe may be changing • more poly drug use, stimulants, cocaine,… • older population heroin injectors with increased service access but likely to remain major consumers of public health resources
Responses • Dramatic increase in services • Substitution treatment and NSE generally now seen as part of a comprehensive drug demand reduction strategy (with other elements) • Although marked differences still exist between countries in terms of approach and the relative balance of services available • Nonetheless estimates now suggest somewhere between a quarter and one half of those with opiate problems now receiving substitution treatment
Policy context • Data has influenced MS and stimulated resource investment • More policy consensus on the need for comprehensive package of responses including risk reduction interventions, • EU recommendation on the prevention and reduction of health-related harm associated with drug dependence (2003/488/EC) • Measures in the new European Strategy & Drug Action Plan • Better understand effective prevention HIV and HCV • Look at protective factors in low prevalence countries • General support for better monitoring across the board • Increasingly a policy culture of monitoring an assessment and thus more pressure to provide robust data
Data needs for European level monitoring • Improved monitoring of HIV in IDU populations especially targeting high risk populations • More MS providing problem drug use estimates and better strategies to get national estimates or to better understand the available local data • More estimates of IDU in particular • More work on incidence estimation • Better and more comprehensive data on capacity of the treatment system • HCV prevention? • Studies of HIV risk behaviour among NON injecting drug users likely become increasingly important
