The researchers constructed a national data set that included detailed information on opioid prescribing and incidences of prescription opioid and heroin deaths from all U.S. states between 2006 and 2015.
The analysis found that implementing PDMP decreased opioid prescriptions 6.1%.
Despite the reduction, though, the researchers determined the policy did not reduce deaths due to prescription opioids. Additionally, heroin-related deaths increased 50.1% under PDMP mandates.
Kim speculates that placing supply restrictions on prescription opioids might have led patients to seek out dangerous and illegal alternatives.
