Enhancing Cardiac Rehabilitation Attendance After Secondary Myocardial Infarction Through Clinician Messaging and Motivational Calls

Conditions

• Type 2 Myocardial Infarction

Eligibility Criteria

Sex

ALL

Age

18 Years - N/A

Healthy Volunteers

Not accepted

Interventions

• Clinician-level intervention — BEHAVIORAL
  The inpatient clinical team receives an EPIC in-basket and email detailing the patient's study participation, benefits of cardiac rehabilitation, and guidance on how to place a cardiac referral if appropriate. If a cardiac rehabilitation referral is not placed within 3 days post-discharge, a follow-up message is sent to one of the patient's outpatient clinician within 4-28 days post-discharge and within 140 days of randomization.
• Patient-level intervention — BEHAVIORAL
  Participants receive a phone call applying motivational interviewing principles if a cardiac rehabilitation referral has been placed by their clinical team within 56 days post-discharge and within 140 days of randomization. The phone call aims to discuss cardiac rehabilitation, barriers to participation, and support engagement in cardiac rehabilitation.

Study Details

The goal of this clinical trial is to determine if a behavioral intervention can increase attendance at cardiac rehabilitation (CR) after secondary/type 2 myocardial infarction in adult patients. The main question it aims to answer is: * Does the ATTEND-CR intervention increase attendance at ≥1 CR exercise session within 140 days of randomization? * Does the intervention increase completion of ≥12 CR exercise sessions within 140 days of randomization? Researchers will compare participants receiving the ATTEND-CR intervention (clinician notifications and a motivational interviewing participant phone call) to usual care to see if attendance and completion of CR improve. Participants: * Clinicians will receive informational messaging regarding CR and the referral process * Participate in a motivational interviewing phone call (intervention group only) * Have follow-up assessments via telephone and electronic health record (EHR) review to track CR attendance, clinical events, and health outcomes

Arms

• Experimental: Intervention Arm (ATTEND-CR):
  Participants clinicians receive an informational message about cardiac rehabilitation and the cardiac rehabilitation referral process. Participants who are referred to cardiac rehabilitation receive a phone call post-discharge applying principles of motivational interviewing. The goal is to encourage cardiac rehabilitation attendance.
• No Intervention: Usual Care Arm
  Participants receive standard post-MI care without clinician informative messaging or a motivational interviewing phone call from the study team. They may still be referred to and attend CR based on usual clinical practice.

Primary Outcome Measure

Number of Participants Who Attended one or more Cardiac Rehabilitation Exercise Session [ Time Frame: Within 140 days (inclusive) post-randomization ]
