Knowledge and experience of cardiopulmonary resuscitation among cardiologists in clinical practice: A multicenter cross-sectional study

Objective: This study aimed to investigate the theoretical knowledge and clinical experience of cardiopulmonary resuscitation (CPR) among Turkish cardiologists according to the recommendations of the 2015 European Resuscitation Council (ERC) guidelines.
Methods: A total of 120 cardiologists from 14 different medical centers (six university and eight research-education hospitals) in İstanbul were included in the study. The questionnaire consisting of 29 open-ended and multiple choice questions on CPR was used and validated based on the ERC guidelines published in 2015. The percentage of correct answers was calculated for each participant.
Results: Of the 120 cardiologists included in this study, 108 (90%) accepted the participation, and the median percentage of correct answers for theoretical questions was 53% (38-72). The percentage of correct answers for interventional cardiologists (48%, n=52) was significantly higher [60% (50–66) vs. 46% (38-52), p<0.001]. Regarding the type of medical centers, no statictical difference was found in terms of theoretical knowledge on CPR [57% (50-72) university hospitals vs. 49% (41-57) research-education hospitals, p=0.160). Peri-arrest transthoracic echocardiography was used in 71% of cases. The ratio of participants who had received an advanced cardiac life support course in the preceding year was only 19% (n=20), and those participants had a significantly higher score regarding the CPR theoretical knowledge questions [68% (54-70) vs. 46% (38-51), p<0.001].
Conclusion: The theoretical knowledge of cardiologists on CPR is not satisfactory according to the 2015 ERC guidelines. An increased frequency of CPR training courses may improve this result.
