A clear understanding of the public ability to access EMS can help to guide interventions aimed at enhancing community preparedness for emergencies.

This scoping review encompassed articles published since 2004 that reported the proportion of subjects who knew emergency phone numbers. Data sources included PubMed, Google Scholar, and references of included articles. Relevant data from eligible publications were extracted manually to an author-developed data-charting sheet and analyzed descriptively. Forty-eight articles were analyzed. Reported studies, mostly cross-sectional surveys, were conducted in 26 countries, including 16 high-income, 9 middle-income, and 1 low-income country. The percentage of subjects who knew emergency numbers varied from 0% to 97.8% (median, 64.3%; interquartile range [IQR], 32.8%-80.0%).
