Introduction. The latest Guidelines for cardiopulmonary resuscitation (CPR) were published in 2010. The aim of the imple-mentation of basic life support (BLS) guidelines is the introduction of uniform criteria within the domain of cardiac arrest diagnostics and treatment both for lay rescuers and first line lifesavers without formal medical education as well as for medical personnel who happen to be in the role of the event witness but without medical equipment and outside of their working place. 

Objective. The goal of this study was to investigate the significance of pre-existing knowledge of the latest 2010 Guidelines for CPR for achieving successful training in BLS among 6th year students of the Belgrade School of Medicine. Methods. In a five-month prospective study of 6th year medical students doing a clinical internship at the Belgrade Emergen-cy Medical Services (EMS) were in a peer training on the application of BLS. At the beginning and at the end of the training program, the students had to pass entrance (E) and final (F) tests composed of 25 identical questions. Using the E test, the students’ knowledge of the latest CPR Guidelines was tested; they were classified into groups with pre-existing knowledge (group I) and groups without pre-existing knowledge (group II). By comparing data from E and F tests we analyzed the influence of training on the improvement of pre-existing knowledge or gaining new knowledge in BLS and first aid. Results. A total of 423 students were tested. The analysis of obtained data showed that in group I there was a statistically significant difference between correct and incorrect responses to eleven questions on the F and E tests. In group II there was a statistically significant difference between test responses in the E and F tests to 17 questions. In group II, knowled-ge additionally improved after training so that in the F test, a statistical significance in correct answers was achieved with regard to 8 questions in relation to the E test (p<0.05). There was a statistically significant difference between correct and inaccurate answers in tests F and E with regard to 10 questions. In the entire group of students, a total statistical significance (p<0.05) was achieved in answers to as much as 25 questions. 

Conclusion. Among 6th year medical students without pre-existing knowledge of the latest 2010 CPR Guidelines, BLS trai-ning considerably improved their previously acquired knowledge. Also, students with good pre-existing knowledge, showed a considerably higher level of acquired knowledge after implemented training. A future study with a longer follow-up period to estimate the effect on long-term retention of learning outcomes is needed.
