Background Chest pain is one of the most common reasons for presentation to the emergency department (ED); however, there is a paucity of data evaluating the impact of physician follow-up and subsequent management. To evaluate the impact of physician follow-up for low-risk chest pain patients after ED assessment. Methods We performed a retrospective observational study of low-risk chest pain patients who were assessed and discharged home from an Ontario ED. Low risk was defined as >= 50 years of age and no diabetes or preexisting cardiovascular disease. Follow-up within 30 days was stratified as (a) no physician, (b) primary care physician (PCP) alone, (c) PCP with cardiologist, and (d) cardiologist alone. The primary outcome was death or myocardial infarction (MI) at 1 year. Results Among 216,527 patients, 29% had no-physician, 60% had PCP-alone, 8% had PCP with cardiologist, and 4% had cardiologist-alone follow-up after ED discharge. The mean age of the study cohort was 64.2 years, and 42% of the patients were male. After adjusting for important differences in baseline characteristics between physician follow-up groups, the adjusted hazard ratios for death or MI were 1.07 (95% CI 1.00-1.14) for the PCP group, 0.81 (95% CI 0.72-0.91) for the PCP with cardiologist group, and 0.87 (95% CI 0.74-1.02) for the cardiologist alone group, as compared with patients who had no follow-up. Conclusion In this cohort of low-risk patients who presented to an ED with chest pain, follow-up with a PCP and cardiologist was associated with significantly reduced risk of death or MI at 1 year.
