Formal cardiac rehabilitation (CR) programs result in decreased cardiovascular and all-cause mortality. Despite overwhelming evidence for the benefits of contemporary CR, fewer than 20% of patients with coronary artery disease participate in such programs, highlighting the vast underutilization of these services, especially in older adults and women. PURPOSE: To quantify/clarify physician perceptions of formalized secondary prevention initiatives and to evaluate CR referral patterns, with specific reference to physician lifestyle practices. METHODS: A 23-item questionnaire was developed and sent to all Michigan cardiologists (N = 840) registered with the American College of Cardiology. The survey, which included a stamped return envelope, was designed to assess referral patterns, perceived benefits of CR, insurance coverage and personal therapeutic lifestyle practices. RESULTS: Of the surveys mailed (N = 840), 105 (13%) were returned by the requested deadline. Most respondents had practices in urban areas (73%), knew of a hospital-based CR program in close proximity (99%), and referred their patients to CR “routinely” (97%). Whereas 92% of respondents felt that CR decreased morbidity, 63% believed that CR decreased mortality. The majority of cardiologist respondents (64%) referred ? 70% of their eligible patients, independent of gender; however, 35% stated a patient's age influences the rate of referral. An increase in exercise tolerance, serial monitoring, education, and improved patient outcomes were the most commonly cited rationale for referral. Respondents who took a cholesterol-lowering statin each day tended to have higher referral rates of all eligible patients (P ≤ 0.05). Although 65% of respondents participated in personal exercise programs at least 3 days/week for at least 30 min/day, there was no relationship between exercise frequency and the reported referral rate to CR. CONCLUSION: These findings indicate that selected personal lifestyle practices among cardiologists may be associated with their referral rates to CR. Primary rationale for referral to CR include increased exercise tolerance, serial monitoring, education, and improved patient outcomes. These data have relevance to CR program staff in clarifying the utilization of services among referring physicians.
