Continuous monitoring of out-of-hospital cardiac arrest in municipality Sombor - EuReCa_Srbija

Aims: Epidemiological follow up of out-of-hospital cardiac arrest (OHCA) in Municipality Sombor in period of 1st of January 2016 until 1st of June 2017. With focus on OHCA quality management. METODOLOGIJA: The project EuReCa is a part of a metacentric, observational, prospective study of an observational trail of the European Resuscitation Council registered Clinical Trial NCT02236819 and approved by the US healthcare authorities. The EuReCa_Srbija project is conducted by the Serbian Resuscitation Council, based on collaboration with the European Resuscitation Council with support of the Section of Emergency Medicine - Serbian Physicians Society. The data's from the Serbian cardiac arrest registry has been collected and analyzed via www.eureca.rs application. Results: Emergency medical service (EMS) in Sombor covers 85.900 citizens. In observed period 119 (138,5/100.000) OHCA's were registered. Cardiopulmonary resuscitation (CPR) was applied 94 (109,4/100.000) cases. Gender distribution shows that 58 OHCA occurred in male and 36 in female population. The most common etiological cause of OHCA had cardiac background in 61 (71/100.000) patinets. Home is the most common place where OHCA occurred in 69 cases with incidence 80,3/100.000). Witness was present 61 OHCA (71/100.000), and lay-person CPR was performed in 19 (22/100.000) patients until the arrival of the EMS. TeleCPR by the dispatcher was registered in 14 (16,2/100.000) cases. The initial shockable rhythm (pulseless ventricular tachycardia pVT /ventricular fibrillation VF) was observed in 30 (34,9/100.000) patients, and nonshockable rhythm (asistoly/ PEA) in 64 (74,5/100.000). Automated external defibrillator (AED) was never used. Return of spontaneous circulation (ROSC) was achieved in 51 (59,3/100.000) cases. At circadian ROSC distributionROSC was most commonly achieved in period between 6-14 hours. Hospital OHCA discharge survival was 6 (6,9/100.000), and the 30-days survival rate is 4 (4,6/100.000). Conclusion: By observing the epidemiological parameters of the OHCA, quality management related points were highlighted. The analyzed data's points to the fact that there is a higher incidence of almost all parameters included in the study protocol compared to previous period. Further observation and analysis will contribute to overall deeper insight of each observed segment that contributed to better and improved outcome with aim to continue the trend of positivity.
