  1. Drug Misuse Monitoring Identifying Trends Predicting Future Demands Responding to Public Health Needs J McVeigh, MA Bellis & R Thomson

  2. Drug Misuse Monitoring • Why do we need a robust drug misuse intelligence system? • Who contributes to the system? • What are the applications of the system?

  3. Reasons for a robust drug misuse intelligence system • Monitor progress of the National Drug Strategy • Assess the needs of specific geographical areas • Identify effectiveness of interventions • Inform effective commissioning of services • Identify trends in substance misuse • Predict changes in drug service demand • Identify and respond to public health issues • Support original research

  4. Contributors to the system Pseudoanonymised data from: • Health • Specialist drug services • Agency based syringe exchange services • Pharmacy based syringe exchange services • Criminal Justice • Arrest referral schemes • Probation • Police arrest data • Youth offending teams • Additional providers • Social services • Housing • Young people's services

  5. Applications of the drug misuse intelligence system • Independent database outputs • Multiple database outputs • Retrospective analyses • Responding to public health needs

  6. Independent database outputs Merseyside & Cheshire specialist drug service contacts (2000/1)

  7. Independent database outputs specialist drug services outcomes (2000/1)

  8. Multiple database outputs Merseyside multiple agency contacts: 1/10/2000 - 31/3/2001 SES 1743 514 10.9% SS 109 AR 938 240 5.1% 28 0.6% SDA 4730 294 6.2% 29 0.6% Probation 2575 Police 546

  9. Multiple database outputs Estimate of hidden/total populations of problematic drug users in Liverpool (1998) Police 245 SDA 1847 198 1799 34 1 12 13 12 Probation 38 Data sources used to estimate total number of problematic drug usersEstimated Total = 7121 (aged 15-44)

  10. Multiple database outputs Area Percentage of Estimated Total Reported in Treatment Percentage of estimated total of problematic drug users reported in treatment All Users Males Females 15-24 25-44 Liverpool 26.6% 22.1% 40.1% 21.0% 27.8% Sefton 30.6% 25.8% 48.0% 14.1% 36.1% * St Helens & Knowsley 26.2% 20.9% 49.5% 18.8% 30.0% ** Wirral 46.5% 42.6% 57.1% 29.5% 51.8% ** ** * 1998 **1999 A higher percentage of females and those aged 25-44 accessing treatment services

  11. Retrospective data analyses Problematic drug use reported by Merseyside & Cheshire SDA

  12. Retrospective data analyses *Provisional data Main drug of use - new clients presenting to agency based syringe exchange schemes in Merseyside & Cheshire

  13. Responding to public health needs Unexplained deaths among injecting drug users in NW England: A case control study using Regional Drug Misuse Database • April – June 2000 14 cases in North West (12 fatalities) • Need to: • Understand the outbreak • Identify characteristics of those most at risk • Provide harm reduction information and advice • Prevent re-occurrence of the outbreak • Develop appropriate advice and information in event of re-occurrence • 12/14 cases located on DMD 10 controls per case

  14. Responding to public health needs Unexplained deaths among injecting drug users in NW England: A case control study using Regional Drug Misuse Database • Results: • Cases were significantly more likely to be: • Female • Older • Longer users of heroin • Injected benzodiazepines Application: Development of risk profile Targeting of prevention activities

  15. Developments of the drug misuse intelligence system • Expansion of data providers to the Inter Agency Drug Misuse Database • Extended outcome monitoring • Establishing links with other sources of intelligence • Web based dissemination of drug misuse intelligence

  16. Conclusions Monitor and predict changes in size/characteristics of drug misuse problems and drug service demand Facilitate the planning and evaluation of health and criminal justice interventions with drug misusers Enable a rapid response to public health investigations
