Readmission predicts 90-day mortality after esophagectomy: analysis of surveillance, epidemiology, and end results registry linked to Medicare outcomes.
The purpose of this study was to characterize postesophagectomy readmissions and determine their relationship with subsequent 90-day mortality. It found that one in 5 esophagectomy patients are readmitted early after discharge. Readmitted patients have a 5-fold increase in early mortality.

Can adding laboratory values improve risk-adjustment mortality models using clinical percutaneous cardiac intervention registry data?
The authors predicted in-hospital/30-day mortality with and without appended laboratory data using New York's percutaneous coronary intervention registry data from 2008-2010. They found that adding laboratory data did not significantly improve the risk-adjustment mortality models' performance and did not dramatically change the quality assessment of hospitals.

The value of adding laboratory data to coronary artery bypass grafting registry data to improve models for risk-adjusting provider mortality rates.
The purpose of this study was to determine whether the addition of laboratory data to the clinical database for coronary artery bypass graft (CABG) would identify laboratory variables that are significant independent predictors of short-term (in-hospital / 30-day) mortality. The researchers found that there was no significant difference in the discrimination of the registry model or the combined registry/laboratory model.

Statin therapy after infrainguinal bypass surgery for critical limb ischemia is associated with improved 5-year survival.
The aim of this study was to determine the effect of long-term statin use after lower extremity bypass grafting on patient-related and graft-related outcomes. It found that statin therapy is associated with a 5-year survival benefit after lower extremity bypass in patients with critical limb ischemia. However, 1-year limb-related outcomes were not influenced by statin use in our large observational cohort of patients undergoing revascularization in New England.
