Out‑of‑hospital cardiac arrest (OHCA) is a severe medical condition. Prehospital care plays an essential role in patient survival.
First, the study aimed to evaluate cases of OHCA managed by cardiopulmonary resuscitation (CPR) attempts in Poland in 2018, including their frequency and patient outcomes in terms of survival until hospital admission or transport to the hospital by helicopter emergency medical service (HEMS). Second, the study was performed to identify the predictors of patient survival until hospital admission or transport by HEMS.
It was a case‑control study based on medical records. In 2018, 3 400 000 emergency visits were registered. Patients who were treated by emergency medical service (EMS) ambulance staff using defibrillation and / or administering at least 1 dose of 1 mg of epinephrine were considered to have OHCA managed by CPR attempts.
A total of 26 783 CPR attempts were reported by EMS in Poland in 2018. The incidence of OHCA with CPR attempts in 2018 was 69.7 per 100 000 inhabitants and it varied from 58.9 per 100 000 to 84.5 per 100 000 inhabitants in 16 Polish provinces. The mean survival rate until hospital admission or transport by HEMS was 36.3% and it ranged from 34.5% to 38.3%. Patient survival until hospital admission or transport by HEMS was related to age, sex, emergency site, defibrillation during CPR, the first recorded rhythm, and procedures performed by the EMS personnel.
The rate of OHCA with CPR attempts was similar to that reported in other European countries. Patient survival until hospital admission or transport by HEMS was associated with many well‑‑known, identified nonmodifiable and modifiable factors.
