Background: Emergency general surgery (EGS) admissions account for more than 3 million hospitalizations in the US annually. We aim to better understand characteristics and mortality risk for EGS interhospital transfer patients compared to EGS direct admissions.
Methods: Using the 2002-2011 Nationwide Inpatient Sample we identified patients aged ≥18 years with an EGS admission. Patient demographics, hospitalization characteristics, rates of operation and mortality were compared between patients with interhospital transfer versus direct admissions.
Results: Interhospital transfers comprised 2% of EGS admissions. Interhospital transfers were more likely to be white, male, Medicare insured, and had higher rates of comorbidities. Interhospital transfers underwent more procedures/surgeries and had a higher mortality rate. Mortality remained elevated after controlling for patient characteristics.
Conclusions: Interhospital transfers are at higher risk of mortality and undergo procedures/surgeries more frequently than direct admissions. Identification of contributing factors to this increased mortality may identify opportunities for decreasing mortality rate in EGS transfers.
