Objective: To investigate the determinants of death in victims of cardiac arrest occurring in out-of-hospital settings. Methods: In this retrospective study, we analyzed 261 care records of people who had cardiac arrest in an extra-hospital environment in 2018 and were served by the Ambulance Service (SAMU-192), in a city in the state of São Paulo, Brazil. Results: The mean age of all patients was 71 years (SD 18.7), and most were male (142; 54.4%). Despite the ambulance team arriving in less than 10 minutes for 150 cases (57.5%), only 56 patients (19.1%) did not die on site. Death was associated with increasing age (p < 0.001; OR = 1.04; CI = 1.02–1.06) and the cardiac arrest occurring at home (p < 0.001; OR = 5.60; CI= 2.48–2.61). Conclusion: Elderly people who had cardiac arrest at home had a greater chance of death. The results also showed that laypeople aren’t equipped to assist in an out-of-hospital cardiac arrest. Implications for the practice: Constant improvement of nursing staff through CPR training is essential to ensure their skills are adequate for emergency care.
