Failure to rescue after major abdominal surgery: The role of hospital safety net burden.

Background: We aimed to examine whether safety-net burden is a significant predictor of failure-to-rescue (FTR) after major abdominal surgery controlling for patient and hospital characteristics, including surgical volume.
Methods: Data were extracted from the 2007-2011 Nationwide Inpatient Sample. FTR was defined as mortality among patients experiencing major postoperative complications. Differences in rates of complications, mortality, and FTR across quartiles of safety-net burden were assessed with univariate analyses. Multilevel regression models were constructed to estimate the association between FTR and safety-net burden.
Results: Among 238,645 patients, the incidence of perioperative complications, in-hospital mortality, and FTR were 33.7%, 4.4%, and 11.8%, respectively. All the outcomes significantly increased across the quartiles of safety-net burden. In the multilevel regression analyses, safety-net burden was a significant predictor of FTR after adjustment for patient and hospital characteristics, including hospital volume.
Conclusion: Increasing hospital safety-net burden is associated with higher odds of FTR for major abdominal surgery.
