Limitations of chest pain follow-up from an urban teaching hospital emergency department

Abstract

Close outpatient follow-up of chest pain patients released from the emergency department (ED) has been suggested as an important means of detecting atypical presentations of cardiac ischemia. Urban teaching hospital patient populations often have limited private physician follow-up options and rely upon standard teaching hospital clinic systems. We analyzed the follow-up of 318 patients 30 or more years of age with nontraumatic chest pain released from the ED of a large urban teaching hospital. The planned disposition of the released patients was as follows: a medical clinic (136), another clinic or a private physician (76), or ED "as needed" (98); in addition, some patients left against medical advice (AMA) (8). The medical clinics received only 38% (51/136) of planned referrals. No subsequent record could be found for 13% (17/136) of referred patients. Only 17% (23/136) of referred patients were reevaluated within seven days. Two of the patients referred to medical clinics were admitted to the hospital within 24 hours for unstable angina and another was admitted from a medical clinic 16 days after ED evaluation with an acute myocardial infarction. Of patients with ED follow-up "as needed," one patient required admission for unstable angina 27 days after ED evaluation. Of the patients who left AMA, only two were reevaluated within 30 days. These findings suggest that specific measures to enhance follow-up must be instituted at urban teaching hospitals if chest pain patients are to be closely followed after ED release.
