Key result
Increased AED availability linked to an ~80% reduction in sudden death in Japanese schools.
Why the study?
Does the availability of AEDs and emergency life-saving measures by school staff reduce the incidence of sudden cardiac death in students under school supervision?
Observational
Does the availability of AEDs and emergency life-saving measures by school staff reduce the incidence of sudden cardiac death in students under school supervision?
The widespread use of AEDs and emergency life-saving measures by school staff has significantly reduced the incidence of sudden cardiac death among students in Japan.
May support school AED programs; leaves open causal confirmation and generalizability beyond supervised settings.

Mamoru Ayusawa (2016) conducted an observational in Sudden cardiac death and sudden cardiac arrest. Automated external defibrillator (AED) availability vs. Historical period before AED availability (1980s) was evaluated on Incidence of sudden death per 100,000 students per year. The incidence of sudden death in Japanese schools decreased from 0.5 per 100,000 students in the 1980s to less than 0.1 per 100,000 after 2010, coinciding with increased availability of automated external defibrillators.
