A Survey Of The Emergency Situation Of Sudden Cardiac Death In The Chinese Population And A Clinical Study Of Sudden Cardiac Death In The Physician Population

Background: Out-of-hospital cardiac arrest(OHCA)strikes over 540,000 people annually in public places in China.Despite evidence-supported interventions such as rapid cardiopulmonary resuscitation(CPR)and defibrillation,fewer than 25% of patients survive in public OHCA events.Little is known about the proportion of Chinese adults trained in CPR or their knowledge of or willingness to learn CPR and use automated external defibrillators(AEDs).Methods: A face-to-face questionnaire survey of the knowledge of and attitudes toward using CPR and AED during an OHCA was conducted in three high-traffic train stations in Hangzhou and Taizhou,China.The survey included questions on previous experience with CPR,recognition of cardiac arrest,CPR-related concerns,and knowledge of AEDs.Results: All of the interviewed participants(n = 6,268)were surveyed about their knowledge of and attitudes toward CPR and AED.A total of 5,981 questionnaires were effectively recovered,including 3,008 from females(50.2%)and 2,973 from males(49.8%).The participants were geographically distributed as follows: 18.5%from western China,19.5% from central China,and 77.0% from eastern China.The education level,regular residence,gender,and legislative policies were also relevant to OHCA.Our results showed that men were more active than women in CPR training and implementation,as well as in knowledge and implementation of AED.More people in eastern and central China had witnessed CPR performance,would pay for CPR training,and would be willing to perform CPR,if there is a legislative policy.Moreover,educational background was critical to the knowledge of and attitudes toward CPR and AED in OHCA.Conclusion:We found that Chinese citizens lack CPR and AED knowledge and training compared with citizens of other developed countries.We recommend that the state aim to raise public awareness of CPR and AED in China.Mass education,policy implementation,specialized training,and legislative action should be carried out.Background: Sudden cardiac death is a serious occupational health threat faced by Chinese doctors.Knowing the working and living conditions of Chinese doctors will help implement targeted preventive measures.Subject and method: We collected demographic and clinical information about all sudden cardiac deaths among Chinese doctors from 2012 to 2019.Next,we conducted a questionnaire survey.Chinese doctors were selected using stratified random sampling.A total of 1,231 valid questionnaires were collected from doctors in western,eastern,and central China from November 10 to November 17,2019.We used correspondence analysis to explore the relationship between workload,sleep time,night shift and physical health.Result: A total of 143 Chinese doctors suffered sudden cardiac death from 2012 to 2019.The overall incidence was on the rise during this time period.Sudden cardiac deaths primarily occurred in males,doctors aged 30 to 39 years,and doctors in eastern China.The corresponding analysis showed that more night shifts,less sleep,and heavier workload were associated with the occurrence of sudden cardiac deaths among Chinese doctors.Conclusion: These findings suggest that greater workloads and increasingly strenuous conditions likely pose a risk to doctors' survival,in addition to potential implications for the quality of patient care.Sudden cardiac death has emerged as a new occupational threat,which should be addressed with multidimensional approaches and policies.
