Implication

Broad campaigns show no overall benefit; supports targeted education in patients with prior AMI.

Key Points

To assess whether a 10-month direct mail campaign using distinct message framings reduces prehospital delay and increases 911 emergency medical service utilization during acute myocardial infarction.
Conducted a prospective, randomized controlled trial evaluated over a 10-month intervention timeframe.
Assigned participants to a control group or to one of three intervention arms receiving educational brochures featuring informational, emotional, or social messages.
Educational mailings yielded no observable intervention effect on emergency service use or delay times within the broader study population.
Emergency medical service 911 use was meaningfully higher across all three brochure intervention groups compared with controls specifically among patients with prior acute myocardial infarction who were discharged with recurrent infarction.

Structured PICO

Does a direct mail campaign increase 911 use and reduce prehospital delay in individuals experiencing acute myocardial infarction symptoms?

Population

Individuals experiencing acute myocardial infarction symptoms

Intervention

10-month direct mail campaign using brochures with informational, emotional, or social messages

Comparator

Control group

Outcome

Use of emergency medical services via 911 calls and prehospital delay

A direct mail campaign aimed at reducing prehospital delay for AMI symptoms was only effective in increasing 911 use among high-risk patients with a prior history of AMI.
