Methods	DETAILS OF STUDY AIM OF INTERVENTION: to increase patient knowledge in six content areas. AIM OF STUDY: to investigate the effect of a planned telephone follow‐up program to provide information and support to post myocardial infarction patients at home in the 6 to 8 week period after hospital discharge. STUDY DESIGN: CCT. METHODS OF RECRUITMENT OF PARTICIPANTS: all patients entering the coronary care unit with a diagnosis of MI were eligible; further procedure unclear. INCLUSION CRITERIA FOR PARTICIPATION IN STUDY: Myocardial infarction/ able to communicate in english/ have a telephone. EXCLUSION CRITERIA FOR PARTICIPATION IN STUDY: disoriented to time place or person/ history of previous MI/ psychiatric history/ too ill/ not able to return at the clinic at 2 months afterwards.

Interventions	DETAILS OF INTERVENTION: the cardiac rehabilitation research nurse made the follow‐up phone calls; they assessed understanding of teaching done before discharge. Information that was unclear or confusing was clarified and new information introduced. To promote retention of information, topic areas addressed during each call included each of the six teaching areas of the study. Time was dependent on the patient's difficulty or ease in remembering or understanding the information provided. Approximately 3 calls were made to each subject; additional follow‐up was based on the nurse assessment of the subject's knowledge. DETAILS OF CONTROL: usual care. CO‐INTERVENTION? yes. DETAILS OF CO‐INTERVENTIONS: inhospital teaching. DELIVERY OF INTERVENTION Frequency: 3. First time at day unclear after discharge. Period: 6‐8 weeks. PROVIDERS: nurse. INTERVENTION QUALITY: unclear. FIDELITY/INTEGRITY: unclear.
