Predictive factors of the absence cardiopulmonary resuscitation by the first bystander of an out-of-hospital cardiac arrest in Reunion island ; Facteurs prédictifs de l’absence de réanimation cardiopulmonaire débutée par le premier témoin lors d’un arrêt cardiorespiratoire extrahospitalier à La Réunion

BACKGROUND: Cardiopulmonary arrest (ACR) is an emergency whose prognosis is closely linked to the speed of management. In 2015, ILCOR placed particular emphasis on the role of dispatchers, who must provide telephone support to bystanders to identify an ACR and initiate basic CPR. The main objective was therefore to highlight the predictive factors of the absence of CPR started by the first bystander during an ACR regulated by our center 15. METHODS: Ret-rospective, analytical and observational study carried out from the RéAC database between June 1, 2013 and December 31, 2016, dealing with victims of out-of-hospital cardiac arrests in Reun-ion that required a call to SAMU 974. RESULTS: 819 patients were included. Sex ratio H / F 1.91 and median age 62 [48-75] years. Predictive factors independently associated with an ab-sence of CPR by the first control: age ≥ 70 years (OR: 0.648, 95% CI: 0.451 - 0.931, p = 0.019), dialing 18 as the emergency number (OR: 0.689, 95% CI: 0.479 - 0.993, p = 0.046), to be at the end-of-life (OR: 0.254, 95% CI: 0.069 - 0.926; p = 0.038), having a psychiatric history (OR: 0.223, 95% CI: 0.071 - 0.702, p = 0.010). Protective factors favoring the initiation of CPR: hav-ing a first-aid bystander and / or health professional (OR: 29.06, 95% CI: 14.27 - 59.18, p < 0.001), having telephone advice ( OR: 3.810, 95% CI: 2.084 - 6.963, p < 0.001), ACR diag-nosed by medical dispatcher (OR: 2.617, 95% CI: 1.386 - 4.940, p = 0.003). CONCLUSION: There are various factors predicting the absence of CPR, hence the interest to consider the im-pact of the implementation of a protocol to standardize dispatchers practices. ; INTRODUCTION : L’arrêt cardio-respiratoire (ACR) est une urgence dont le pronostic est étroitement lié à la rapidité de la prise en charge.
