    Abstract:
    UNLABELLED: Reduction in emergency department (ED) overcrowding is a major Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) initiative. One major source of ED overcrowding is patients waiting for telemetry beds. OBJECTIVE: To determine whether, in patients admitted with a potential acute coronary syndrome, a negative evaluation for underlying coronary artery disease would reduce ED and hospital revisits over the subsequent year compared with patients who did not receive an evaluation for underlying coronary artery disease. METHODS: Nine hundred ninety-nine consecutive patients admitted for potential acute coronary syndromes through the ED during a one-year period were screened for inclusion. Patients who had a negative evaluation for underlying coronary disease were compared with patients who were not evaluated for underlying coronary artery disease for subsequent ED visits, hospital admissions, and cardiac resource utilization over the year following the index visit via a health system-wide computerized record review. Patients with positive tests or biomarkers at the index visit were excluded. Each repeat visit was rated as "potentially cardiac" or "noncardiac." Results of echocardiograms, stress tests, and catheterizations and information about in-hospital deaths were obtained. RESULTS: Six hundred ninety-two patients met the inclusion criteria: 556 patients received no evaluation for underlying coronary artery disease, 116 had a negative stress test, and 20 had a negative cardiac catheterization during the index visit. Patients with no evaluation for underlying coronary artery disease and patients with a negative evaluation had similar likelihoods of a repeat ED visit (negative test 39.0% vs. no test 40.3%; p = 0.85) and repeat hospital admission (28.7% vs. 31.5%; p = 0.61). The rates of a potentially cardiac-related ED visit (21.3 vs. 23.4%; p = 0.65) and hospital admission (17.7% vs. 20.7%; p = 0.48) were not significantly different. The two populations had similar utilization rates of echocardiograms, stress tests, and catheterizations (p > 0.70 for all). CONCLUSIONS: For patients admitted to the authors' institution with a potential acute coronary syndrome, there was no association between a negative evaluation for underlying coronary artery disease and overall or potentially cardiac ED visits, admissions, or cardiac resource test utilization over the year following the index visit.
