This study investigated demographic trends over time in the use of prescription opioids versus heroin among addicted individuals. ICD9 codes associated with hospitalizations for overdoses from either prescription opioids (POD) or heroin (HOD) were harvested from the Nationwide Inpatient Sample (NIS) for the years 1993 through 2009, inclusive. Population data were taken from U.S. Census statistics. Demographic specific rates of POD and HOD hospital admissions were analyzed to determine if fluctuations in the dynamics of one form of opiate, such as supply-based reduction, are correlated with changes in the rates of overdoses of the other. Dataset includes statistical and demographic data.
