Regular organization and mandatory attendance of cardiopulmonary resuscitation (CPR) courses for healthcare professionals (HCP) at all levels of the healthcare system should be a common practice. In the Republic of Croatia, the regularity of course attendance is arbitrary. We have organized CPR courses for HCPs of the Osijek-Baranja County Health Center several times so far.  On average, 25-30% of HCPs of our institution attend the courses, and a smaller percentage regularly repeat them.  Since 2019, a written exam has been an integral part of the course. We compared the answers to the questions before the courses organized in 2019 and 2022, as well as the answers after the course organized in 2019. The average percentage of correct answers on the 2019 initial exam was 58%, while on the final exam it was 83%. The average percentage of correct answers on the 2022 initial exam was 66%, but repeaters achieved an average of 75% correct answers. Conclusion: Knowledge of proper CPR procedures among healthcare professionals declines over time, and regular retraining reduces knowledge fluctuation. Three years after the course, repeaters achieve a better average of correct answers on the initial test.
