Interhospital transfer for emergency general surgery: An independent predictor of mortality

      Highlights

      • EGS interhospital transfers have higher rates of mortality than direct admissions.
      • Direct admissions are less likely to have a procedure or surgery than transfers.
      • Odds of mortality remain elevated despite controlling for patient characteristics.

      Abstract

      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.
