Background A specific risk model concerning mortality of patients undergoing isolated
coronary artery bypass grafting (CABG) is developed based on the national quality …

Background—The predictive performance of static risk prediction models such as
EuroSCORE deteriorates over time. We aimed to explore different methods for continuous …

BACKGROUND: Intradepartmental and interdepartmental benchmarking requires scoring
systems with reliability (calibration) and stability over the complete spectrum of …

Background Risk-adjusted mortality (RAM) models are increasingly used to evaluate
hospital performance, but the validity of the RAM method has been questioned. Providers …

Risk models play a vital role in monitoring health care performances. Despite extensive
research and widespread use of risk models in cardiac surgery, there are methodologic …

Background. The aim of the study was to compare the accuracy of general scoring systems
on ICU arrival with preoperative evaluation using the EuroSCORE risk model in patients …

Background. In the process of risk stratification, a logistic calculation of mortality risk in
percentage is easier to interpret. Unfortunately, there is no reliable logistic model available …

The use of hierarchical logistic regression for provider profiling has been recommended due
to the clustering of patients within hospitals, but has some associated difficulties. We assess …

INTRODUCTION AND OBJECTIVES: Previous studies suggest that the effectiveness of
coronary surgery is influenced by the type of management at the healthcare centre where …

Objective To review the Department of Veteran Affairs (VA) and the Society of Thoracic
Surgeons (STS) national databases over the past 10 years to evaluate their relative …
