RESUMO
OBJECTIVE: Reporting epidemiological data on prehospital cardiac arrest in the Pilsen Region in 2022. Expression of cardiopulmonary resuscitation success using the Cerebral Performance Category (CPC) score. MATERIALS AND METHODS: The study looked at the survival rate of out-of-hospital sudden cardiac arrest in all patients in whom emergency medical services performed cardiopulmonary resuscitation (CPR). The study covered the period from 1 January 2022 to 31 December 2022. Both electronic and paper medical records were used to obtain data. All cases were evaluated according to Utstein-style guidelines. RESULTS: During the studied period, emergency response teams in the Pilsen Region carried out CPR in 499 cases. The incidence of prehospital CPR was 88.43 cases per 100,000 population. A total of 146 patients (29.26%) were referred to the hospital with spontaneous circulation, and results indicating survival with a good neurological outcome of CPC 1 or 2 were recorded in 48 cases (9.62%). The first monitored rhythm was shockable in 119 cases (23.85%). In this subgroup, ROSC was achieved in 71 cases (59.66%) and 61 of them (51.26%) were referred to hospital. In this study subgroup, a total of 36 patients (30.25%) achieved a good neurological outcome with a CPC score of 1 or 2. CONCLUSION: The study presented epidemiological data on OHCA and prehospital CPR in the Pilsen region in 2022. The data obtained shows a survival rate with good neurological outcome in 9.62% of cases.
