SAMHSA/OAS 44 Nonmedical Use ED Visits: Conclusions Morphine related ED visits nearing 30,000 –Immediate release –Controlled release is similar Highest visit rates in patients aged Majority of patients treated and released Polydrug use is typical
SAMHSA/OAS 45 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 for immediate versus extended release enable better surveillance
