Objective To study the epidemiological characteristics of patients with out-of-hospital cardiac arrest(OHCA)in Xiamen and the factors affecting successful resuscitation,in order to provide comparative evidence for improving the ROSC rate of OHCA Patients cardiopulmonary resuscitation(CPR)in Xiamen region.Methods Design an electronic medical record(EMR)collection template based on the Utstein model,and collect the OHCA patients'information treated by EMS,that occurred from February 1,2024 to July 31,2024 in Xiamen.To study the epidemiological characteristics of 1 270 patients with out-of-hospital cardiac arrest(OHCA)in Xiamen and the factors affecting successful resuscitation.The data was obtained from the dispatch information system EMR and in-hospital medical records.Relevant data is grouped and analyzed using the Utstein model,and statistical methods such as two sample T-test and multiple sample rate comparison chi-square-test are used to analyze the influencing factors of ROSC in OHCA.Results A total of 1 270 patients with OHCA were included in the study,including 863 males(67.95%)and 407 females(32.05%),with an average age of(60.50±18.60)years.CPR was performed in 677 patients(53.31%).The success rate of ROSC was 9.16%(62/677).The survival rate at discharge was 6.79%(46/677).The pre-hospital emergency response time of the attempted CPR group was significantly shorter than that of the non-attempted CPR group(t=5.009,P<0.05),and the proportion of male patients was higher than that of the non-attempted CPR group(χ2=5.787,P=0.016).However,in the CPR group,there was no significant difference in the first aid response time and the proportion of male patients between the ROSC group and the non-ROSC group(t=1.034,P=0.301;χ2=2.116,P=0.146).The survival rate at discharge with good neurological function(CPC 1-2)was 2.51%(17/677).The main causes of attempted CPR in OHCA patients were medical diseases(76.96%)and trauma(9.60%),and the main sites were residence(64.99%)and public places(7.83%).The proportion of ROSC bystanders participating in CPR in OHCA patients was 64.51%,the proportion of bystanders using AED was 6.45%,and the rhythm first monitored by EMS was cardiac arrest(straight line)(53.33%).Conclusion The ROSC rate of OHCA in Xiamen is slightly higher than other regions in China,there is still a significant gap compared to developed countries.
