Background: In-hospital cardiac arrest is a major cause of death in European countries, and survival of patients remains low ranging from 20% to 25%. Aims: The purpose of this study was to assess healthcare professionals' knowledge on cardiopulmonary resuscitation among university hospitals in 12 European countries and correlate it with the return of spontaneous circulation rates of their patients after in-hospital cardiac arrest. Methods and results: A total of 570 healthcare professionals from cardiology, anaesthesiology and intensive care medicine departments of European university hospitals in Italy, Poland, Hungary, Belgium, Spain, Slovakia, Germany, Finland, The Netherlands, Switzerland, France and Greece completed a questionnaire. The questionnaire consisted of 12 questions based on epidemiology data and cardiopulmonary resuscitation training and 26 multiple choice questions on cardiopulmonary resuscitation knowledge. Hospitals in Switzerland scored highest on basic life support (P =0.005) while Belgium hospitals scored highest on advanced life support (P <0.001) and total score in cardiopulmonary resuscitation knowledge (P =0.01). The Swiss hospitals scored highest in cardiopulmonary resuscitation training (P <0.001). Correlation between cardiopulmonary resuscitation knowledge and return of spontaneous circulation rates of patients with in-hospital cardiac arrest demonstrated that each additional correct answer on the advanced life support score results in a further increase in return of spontaneous circulation rates (odds ratio 3.94; 95% confidence interval 2.78 to 5.57; P <0.001). Conclusion: Differences in knowledge about resuscitation and course attendance were found between university hospitals in 12 European countries. Education in cardiopulmonary resuscitation is considered to be vital for patients' return of spontaneous circulation rates after in-hospital cardiac arrest. A higher level of knowledge in advanced life support results in higher return of spontaneous circulation rates. [ABSTRACT FROM AUTHOR]

Background. Recently, it has been suggested that Chlamydia pneumoniae possibly plays a possible role in the pathogenesis of atherosclerosis. We investigated whether treatment with clarithromycin prior to coronary artery bypass graft (CABG) surgery would prevent subsequent cardiovascular events and mortality. Methods. Patients who were scheduled for CABG surgery were randomly assigned to receive either clarithromycin or placebo until the day of surgery in a double-blind trial. During the 2 years of follow-up, mortality and cardiovascular events were assessed. Results. Follow-up at 2 years was achieved for 473 patients. The mean duration of treatment was 16 days. Patient characteristics at baseline were well balanced between the 2 treatment groups. Mortality was equal in the 2 groups: 10 (4.2%) of 238 patients in the clarithromycin group and 9 (3.8%) of 235 patients in the placebo group (relative risk, 1.10; 95% CI, 0.42-2.89; P = 1.0). Also, there were no significant differences in the proportion of patients who experienced cardiovascular events during the follow-up period: 20 (8.4%) of 238 patients in the clarithromycin group and 19 (8.1%) of 235 patients in the placebo group (relative risk, 1.04; 95% CI, 0.55-1.98; P = 1.0). The overall rate of such events was 58 (12.3%) of 473 patients. Conclusions. Treatment with clarithromycin in patients scheduled for CABG surgery did not reduce the subsequent occurrence of cardiovascular events or mortality during a 2-year follow-up period.

Over the past years the number of medical registries has increased sharply. Their value strongly depends on the quality of the data contained in the registry. To optimize data quality, special procedures have to be followed. A literature review and a case study of data quality formed the basis for the development of a framework of procedures for data quality assurance in medical registries. Procedures in the framework have been divided into procedures for the co-ordinating center of the registry (central) and procedures for the centers where the data are collected (local). These central and local procedures are further subdivided into (a) the prevention of insufficient data quality, (b) the detection of imperfect data and their causes, and (c) actions to be taken / corrections. The framework can be used to set up a new registry or to identify procedures in existing registries that need adjustment to improve data quality. [ABSTRACT FROM PUBLISHER]
