Survival depends critically on how quickly help arrives and whether cardiopulmonary resuscitation (CPR) and defibrillation are started early. In recent years, many regions in Europe and Italy, including Emilia-Romagna, have introduced systems that alert nearby volunteers, called First Responders (FRs), through smartphone applications (such as DAE RespondER). These individuals can reach the patient before emergency medical services (EMS) and begin life-saving actions.\n\nThe FIRSST-RER study aims to evaluate whether the intervention of First Responders improves survival in patients with out-of-hospital cardiac arrest in Emilia-Romagna.\n\nThis is a multicentre observational study involving approximately 5,000 adult patients who experienced cardiac arrest between 2018 and 2025 and were treated by the regional emergency system.\n\nThe study compares two groups of patients:\n\nthose who received help from at least one First Responder activated via the app those who did not receive First Responder intervention\n\nThe main objective is to determine whether First Responders increase survival at 30 days after cardiac arrest.\n\nAdditional objectives include evaluating:\n\nsurvival at 6 months and 1 year neurological outcomes (brain function recovery)\n\nData for this study are collected from existing healthcare and emergency system databases, including EMS dispatch records, national health data systems, and the DAE RespondER platform.\n\nFor patients who survive, follow-up information may be collected through medical records or telephone contact.\n\nImportantly, this study does not involve any experimental treatments or changes in patient care. It is based entirely on data already collected during routine emergency care, and therefore does not pose additional risks to patients.\n\nAll data are handled securely and in compliance with privacy regulations. Personal identifiers are replaced with coded information (pseudonymisation), and only authorised researchers can access the data. Patients who are alive may be contacted to provide consent and additional follow-up information; participation is voluntary, and consent can be withdrawn at any time.\n\nThe results of this study will provide important evidence on the effectiveness of citizen responder systems and may help guide future improvements in emergency response organisation, public health strategies, and training programmes. Ultimately, the goal is to increase survival and improve outcomes for people experiencing cardiac arrest in the community.",[57],"Cardiac Arrest (CA)",[59,60,61],"first responder","out of hospital cardiac arrest","survival","NOT_YET_RECRUITING","2026-05-10",{"date":65,"type":66},"2026-05-15","ACTUAL",{"date":68,"type":53},"2026-05",{"date":70,"type":53},"2026-12-31",{"name":5,"class":6},1]
