Background: The History, Electrocardiogram, Age, Risk Factors, Troponin (HEART) score is a prospectively validated risk stratification tool for patients presenting to the emergency department (ED) with chest pain. Data demonstrate that patients with low HEART scores (0-3) can be safely discharged from the ED. ED physicians, however, may be reluctant to discharge patients based on the score.
Objective: To identify specific factors why ED physicians are reluctant to discharge patients with low-risk HEART scores from an ED observation unit (EDOU) without further evaluation.
Methods: This was a single-center prospective, cross-sectional analysis of ED patients from an urban ED placed in an EDOU for evaluation of chest pain, from July 1, 2016, to August 31, 2016. ED physicians completed a questionnaire that included documentation of patient HEART score and if the patient would or would not be a good candidate for outpatient stress testing or follow-up within 72 hours without further EDOU testing or consultant evaluation. Providers selected reasons why patients were not a good candidate for outpatient stress testing/follow-up.
Results: There were 279 patient questionnaires completed, 42% (117/279) had a HEART score of 0-3. Within this group, 54.7% (64/117) of the patients were identified as not being good candidates for outpatient stress testing/follow-up within 72 hours because of concerns for poor follow-up (n = 14), concerning risk factors (n = 14), concerning symptoms (n = 11), and other (n = 7).
Conclusions: ED physicians in this urban ED felt that over half of patients with a low-risk HEART score were not good candidates for discharge from the EDOU without further evaluation due to poor follow-up, concerning risk factors or symptoms, or coexisting conditions.
