The VICAP-CPR study investigates whether doctors and nurses working in Intensive Care can determine neurological outcome and future quality of life after six months in patients treated for cardiac arrest outside the hospital based on clinical assessment in the first 24 hours after admission to Intensive Care. To conduct this study, the results of the questionnaire offered to Intensive Care doctors and nurses regarding the estimation of long-term neurological outcome and quality of life will be compared with the neurological outcome and quality of life as recorded in the STEPCARE study (NCT 05564754). The aim of the international STEPCARE study is to determine the best combination of post-resuscitation care to favourably influence survival and neurological outcome in patients treated for cardiac arrest outside hospital.
