SAMHSA/OAS 2 Today's Agenda No conflicts of interest Overview of DAWN Key findings from 2006 –Nonmedical use of opiates/opioids –2004-2005 comparisons –Extended- vs. immediate-release oxycodone
3
SAMHSA/OAS 3 DAWN Methods Stratified probability sample of hospitals –Short-term, general, nonFederal hospitals with 24-hour emergency departments (EDs) –Oversample areas –Remainder area National estimates account for: –Sample design –Unit nonresponse –Partial nonresponse in responding hospital Entire U.S.

SAMHSA/OAS 4 National Estimates Oversample areas (urban) + Remainder area (urban & rural)

SAMHSA/OAS 29 Nonmedical Use: Number of Drugs, Oxycodone by Release Type, 2006 Source: DAWN estimates for the U.S., 2006 % of ED visits ExtendedUnknownImmediate 1 drug Multiple drugs
30
SAMHSA/OAS 30 Nonmedical-Use ED Visits: Conclusions Opioid analgesics nearing 250,000 visits –¼ Oxycodone ¼ Hydrocodone – in immediate and unknown release types –Polydrug use is typical Highest visit rates in patients aged 21-54 Majority of patients treated and released
31
SAMHSA/OAS 31 Important Considerations: DAWN Depends on ED Medical Records Link between ED visit and use of drug Dose levels and source of drug unavailable Nonspecific drug reports –Opiates/opioids, unspecified (unnamed) –Unknown release-type Unique names enable better surveillance –Generics –Proposed new OxyContin® formulation
