Exploitation of resources and cardiovascular outcomes in low-risk patients with chest pain hospitalized in coronary care units

Abstract

Background

Most patients who present to medical centers due to chest pain do not suffer from acute coronary syndromes and do not need to be hospitalized in coronary care units (CCUs). This study was done to determine exploitation of resources and cardiovascular outcomes in low-risk patients with chest pain hospitalized in CCUs of educational hospitals affiliated with a major medical university.

Methods

Over a 4-month period, 550 patients with chest pain who were hospitalized in the CCUs belonging to six hospitals affiliated to the authors’ medical university were recruited by census method. Using Thrombolysis in Myocardial Infarction risk score, 95 patients (17.27%) were categorized as low-risk patients. This group was evaluated with respect to demographics, bed occupancy rate, mean hospitalization period, expenses during admission, and cardiovascular outcomes in the 30-day period postdischarge.

Results

Mean (± standard deviation) hospitalization duration was 3.04 (±0.71) days. No significant difference was seen between the six surveyed hospitals regarding hospitalization duration (P = 0.602). The highest bed occupancy rate was seen in Taleghani and Shohada Tajrish hospitals and the lowest was in Modarres Hospital. The mean paid treatment expenses by low-risk patients was IRR 2,050,000 (US$205). Mean total hospitalization expenses was US$205. No significant difference was seen between the six surveyed hospitals (P = 0.699). Of the patients studied, 89.5% did not show any cardiovascular complications in 1 month and no deaths occurred.

Conclusion

Given the high bed-occupancy rate by low-risk patients, associated high hospitalization costs, and the lack of cardiovascular complications in patients observed at 1-month follow-up after discharge, it is recommended that appropriate evaluations be performed in emergency units to prevent unnecessary admissions.
