OBJECTIVE To construct a scoring system for the prediction of early mortality in cardiac surgical patients in Europe on the basis of objective risk factors. METHODS The EuroSCORE database was divided into developmental and validation subsets. In the former, risk factors deemed to be objective, credible, obtainable and difficult to falsify were weighted on(More)
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). METHODS From September to November 1995, information on risk factors and mortality was collected for 19030 consecutive adult patients undergoing cardiac surgery under(More)
OBJECTIVE To assess the performance of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) when applied in a North American cardiac surgical population. METHODS The simple additive EuroSCORE model was applied to predict operative mortality (in-hospital or 30-day) in 401684 patients undergoing coronary or valve surgery in 1998 and 1999 as(More)
OBJECTIVE Because of national epidemiological differences in adult heart surgery in Europe, the effectiveness and desirability of a pan-European score for the assessment of quality of surgical care remains controversial. We assessed the predictive value of EuroSCORE in national subsets of the EuroSCORE database. METHODS The EuroSCORE development data set(More)
Purpose: To compare the accuracy and complication rate of two different CT-guided transthoracic needle biopsy techniques: fine needle aspiration and an automated biopsy device. Methods: Two consecutive series of respectively 125 (group A) and 98 (group B) biopsies performed using 20–22 gauge coaxial fine needle aspiration (group A) and an automated 19.5(More)
OBJECTIVES To assess whether the use of the full logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) is superior to the standard additive EuroSCORE in predicting mortality in high-risk cardiac surgical patients. METHODS Both the simple additive EuroSCORE and the full logistic EuroSCORE were applied to 14,799 cardiac surgical(More)
OBJECTIVES To estimate the incidence of adverse events in medical and surgical activity in public and private hospitals, and to assess the clinical situation of patients and the active errors. DESIGN Prospective assessment of adverse events by external senior nursing and doctor investigators with ward staff. SETTING Random three-stage stratified cluster(More)
A prospective study was carried out from January to April 1993 in 42 centers to assess the quality of care in adult heart surgery in France. One hundred eight parameters were collected (i.e., risk factors, surgery, postoperative course) for 7181 patients. Eight simple, objective factors were selected using a multivariate analysis. Point weighting was(More)
