Which data source is commonly used to track fatalities related to drug overdoses?

• A. Mortality data
• B. National Survey on Drug Use and Health (NSDUH)
• C. Emergency department records
• D. Treatment admissions

Answer: (A)

Mortality data from vital records are used to track fatalities related to drug overdoses. Death certificates provide official cause-of-death information, which is codified (for overdoses typically using ICD-10 codes) to generate counts and trend data at national, state, and local levels. This makes mortality data the primary source for understanding how many people are dying from overdoses and how those numbers change over time.

Other data sources serve different purposes but don’t focus on deaths. The National Survey on Drug Use and Health collects information on drug use and related health issues from living individuals, so it estimates prevalence rather than fatalities. Emergency department records capture nonfatal overdoses treated in hospitals, offering insight into acute incidents but not comprehensive fatality counts. Treatment admissions track people entering treatment programs, which also reflects nonfatal cases and treatment demand rather than deaths.

So for tracking overdose fatalities, mortality data are the most appropriate and commonly used source.
