Objective To develop a risk stratification model to assess open heart surgery mortality in
Catalonia (Spain) in order to use risk-adjusted hospital mortality rates as an approach to …

Objective: To study the relationship between predicted and actual mortality in a cardiac
surgical practice and to determine whether there is a consistent relationship across risk …

Objective: To assess risk factors for mortality in cardiac surgical adult patients as part of a
study to develop a European System for Cardiac Operative Risk Evaluation (EuroSCORE) …

Objective To compare the performance of several risk-scoring models to predict surgical
mortality following open heart surgery. Design A prospective observational study. Setting …

BACKGROUND.: Risk-adjusted mortality was previously used to compare institutions as a
whole or surgeons. Because the same surgical team is working in two different hospitals, the …

Objective: Logistic regression is most often used to produce a cardiac operative risk model.
But the logistic equation requires a computer to solve. Thus, simple additive models have …

OBJECTIVES The aim of our study was to investigate early mortality after cardiac surgery
and to determine the most adequate follow-up period for the evaluation of mortality rates …

Conclusions There is a significant variation in patients risk profile and surgical strategy both
within Europe and across the Atlantic. Therefore, it is not appropriate to assess the quality of …

This study aims to develop the first Latin-American risk model that can be used as a simple,
pocket-card graphic score at bedside. The risk model was developed on 2903 patients who …

Objective: During the last decade, a worldwide growing interest in evaluating performance of
health services through 'outcome studies' took place. This study started in early 2002 and …
