  8. Methods (cont.) • Rates age-adjusted according to the 2000 U.S. Census population and calculated per 100,000 population • Differences in unintentional drug poisoning death rates were examined by descriptive factors

  9. Number of Unintentional Drug Poisoning Deaths, Michigan, 1999-2009 Number of deaths Year

  10. Age-Adjusted Unintentional Drug Poisoning Death Rates by Gender, Michigan,1999–2009 Male Total Rate per 100,000 population Female Year

  11. Age-Adjusted Unintentional Drug Poisoning Death Rates by Race, Michigan, 1999–2009 Black White Rate per 100,000 population Year

  12. Unintentional Drug Poisoning Death Rates by Age Groups, Michigan, 1999–2009 45 – 54 years 35– 44 years 25– 34 years Rate per 100,000 population 55-64 years 15-24 years 65+ years Year

  15. Michigan’s 2005 Population by Preparedness Regions Detroit

  16. Unintentional Drug Poisoning Death Rates by Region, Michigan, 1999 Detroit

  17. Unintentional Drug Poisoning Death Rates by Region, Michigan, 2004

  18. Unintentional Drug Poisoning Death Rates by Region, Michigan, 2009

  19. Discussion • Unintentional drug poisoning death rates increased over the past decade in Michigan • Death rates due to opioid analgesics increased more than heroin and cocaine • Increase in deaths closely paralleled the increased number of Rx opioid analgesics statewide

  20. Limitations • Utilization of vital statistics data • Validity and completeness of data • Toxicology testing varies by region/county • Limited access to Michigan’s Prescription Monitoring System

  21. Michigan Initiatives • Increased surveillance by Task Force formed during fentanyl outbreak • RxOTC Drug Abuse Workgroup established in Feb. 2011 • Broaden statewide media message • Broaden education and use of Screening, Brief Intervention, Referral, and Treatment (SBIRT) • Increase access and use of PMP
