Analysis Of Factors Influencing The Success Rate Of Out-of-hospital Cardiopulmonary Resuscitation In Hainan Province

Objective:This study investigated and analyzed out-of-hospital cardiac arrest cases in the northern city of Haikou and the southern city of Sanya,to understand the current situation of out-of-hospital cardiac arrest in Hainan Province,the success rate of out-of-hospital CPR and its influencing factors,and to explore the impact of out-of-hospital CPR in Hainan Province.In order to improve the implementation rate of out-of-hospital CPR,the survival rate and quality of life of patients with out-of-hospital cardiac arrest,and the success rate of out-of-hospital CPR,improve The level of emergency and critical care outside the hospital in Hainan Province will promote the rational allocation of emergency resources,and provide a baseline basis for improving the construction of the first aid system outside the hospital in Hainan Province.Methods:Through the literature method and the previous investigation of out-of-hospital cardiac arrest medical records,a data extraction table for pre-hospital emergency medical records in Hainan Province was designed.There are 2260 medical records of out-of-hospital cardiac arrest in the institution,including 675 medical records of out-of-hospital cardiopulmonary resuscitation.Use Epidata to establish an out-of-hospital cardiac arrest database,use EXCEL2016 to organize and draw the exported medical record data,and use SPSS21.0 to perform K-S normality test,chi-square test,nonparametric test,and multivariate logistic regression analysis to understand Hainan.Status and influencing factors of out-of-hospital cardiac arrest and out-of-hospital cardiopulmonary resuscitation in the province.Results:1.Low implementation rate of out-of-hospital CPRThe implementation rate of out-of-hospital CPR in Hainan Province was 29.87%,and the proportion of patients who had not performed out-of-hospital CPR was70.13%.The proportion of patients receiving out-of-hospital CPR is less than 1/3 of the total number of out-of-hospital cardiac arrest patients,and more than 70% of out-of-hospital cardiac arrest patients have lost their vital signs for rescue before emergency medical service personnel arrive at the scene.This may be one of the main reasons for the low implementation rate of out-of-hospital CPR in Hainan Province.2.The basic situation of out-of-hospital CPROut-of-hospital CPR patients in Haikou City accounted for 76.12% males and23.88% females,and Sanya City out-of-hospital CPR patients accounted for 77.97%males and 22.03% females.Among the out-of-hospital CPR patients,the proportion of males and females was quite different,and the proportion of males was female.more than 3 times.The average age of out-of-hospital CPR patients in Haikou City was 59.00(45.00～72.00)years old,of which the elderly accounted for 61.76%,and the average age of out-of-hospital CPR patients in Sanya City was 59.00(46.00～68.00)years old,of which the elderly accounted for The elderly accounted for more than 60% of the total.Among the minor patients,the number of patients under the age of 5 is relatively large.The proportion of patients under the age of 5 in Haikou City is 0.90% of the number of CPR patients outside the Haikou City General Hospital,and the proportion of patients under the age of 5 in Sanya City is the largest in the Sanya City General Hospital.5.08% of the patients with external cardiopulmonary resuscitation accounted for about 6 times that of Haikou City,of which drowning patients accounted for the main part.There was no statistical difference between the success rate of out-of-hospital CPR in Haikou(7.72%)and the success rate of out-of-hospital CPR in Sanya(8.48%).The in-hospital survival rates of out-of-hospital cardiac arrest in Haikou and Sanya were 2.31% and 2.51%,respectively.The in-hospital survival rates were very low.More than 97% of out-of-hospital cardiac arrest patients died out of hospital.3.Factors influencing the success rate of out-of-hospital CPRThe results of this study showed that there was no statistical difference in the effects of age,cardiovascular and cerebrovascular diseases,place of calling for help,bystanders,ambulance response time and drug use on the effect of out-of-hospital CPR(P>0.05).The difference in the effect of out-of-hospital CPR was statistically significant(P<0.05).The success rate of out-of-hospital CPR in Haikou City was higher than that of women,and the success rate of out-of-hospital CPR in Sanya City was higher for women than for men.There were significant differences in the effect of cardiopulmonary resuscitation(P<0.05),electrical defibrillation was beneficial to the success of out-of-hospital CPR;on-site first aid time had a statistically significant difference in the effect of out-of-hospital CPR in Haikou(P<0.05),multiple factors Logistic regression analysis showed that too long on-site first aid was a risk factor for successful out-of-hospital CPR(OR=0.967,95%CI: 0.954-0.979,P<0.05).Conclusions:The results of this study showed that the implementation rate of out-of-hospital CPR in Hainan Province was low(29.87%),the success rate of out-of-hospital CPR was low(7.85%),and the hospital survival rate was low(2.35%).)was higher than that of women(3.76%),and the success rate of out-of-hospital CPR in Sanya was higher for women(33.33%)than for men(2.13%);electrical defibrillation had a significant impact on the effect of out-of-hospital CPR in Sanya,which was beneficial to the success of out-of-hospital CPR;Excessive on-site first aid time was a risk factor for successful out-of-hospital CPR in Haikou City(OR=0.97,95%CI:0.95-0.98,P<0.05).The study showed that age,cardiovascular and cerebrovascular diseases,place of calling for help,bystanders,ambulance response time,and drug use had no statistical difference in the effect of out-of-hospital CPR,which may be due to the delay in calling for help,the lack of emergency ability of bystanders,and the lack of emergency response.The car response time is too long and other reasons,resulting in a delay in the effective treatment time,and it is caused by the inability to effectively treat patients with out-of-hospital cardiac arrest.
