VDH PUD Overdose ED Visits by Locality and Quarter

This dataset includes the number and rate of drug overdose emergency department (ED) visits among Virginians by year, drug type, geography, and demographics.

Geographic location is assigned based on the patient’s residential zip code. A single zip code may span multiple city and county localities in Virginia. If a patient resides in a spanning zip code, the visit is assigned to the locality where the majority of the population resides. To account for zip codes spanning multiple localities, VDH combines certain Virginia city and county localities to calculate visit counts and rates(see below):
