The ongoing, nationwide, multi-institutional registry of heart surgery procedures in Poland is an initiative of the Club of Polish Cardiac Surgeons in cooperation with the Polish Ministry of Health that commenced in 2006 and collects data from all 37 heart surgery centers in Poland. Centers enrolling patients in the KROK registry are required to transfer the data concerning every cardiac surgery to the central database in the National Centre for Healthcare Information Systems at the Ministry of Health and are financially liable for data integrity and completeness. Follow-up data regarding mortality were obtained from the National Health Fund — the nationwide, obligatory, public health insurance institution in Poland and incorporated to the registry. Since the registry is government funded, institutional board approval is lifted. Patients consent to have data included in the registry upon admission. Data in the registry are anonymous with respect to patients’ identity and heart surgery centre.
