RESUMEN
Objective:The aim of this study was to investigate the clinical characteristics and analyze the risk factors of patients with acute dichlorvos poisoning combined with shock.Methods:The clinical data of patients with acute dichlorvos poisoning admitted to the Peking University Third Hospital and the Fifth Medical Center of the PLA General Hospital between January 2019 and September 2020 were retrospectively analyzed, and demographic data, poisoning, clinical manifestations, laboratory tests, therapeutic measures and clinical outcomes were collected to establish a clinical database. The patients were divided into two groups: the shock group and the non-shock group, and the clinical data were compared between the two groups to analyze the clinical characteristics and prognosis of shock in acute dichlorvos poisoning, and the risk factors of shock in acute dichlorvos poisoning were analyzed by logistic regression.Results:A total of 134 patients who met the criteria for acute dichlorvos poisoning were included in this study; the incidence of shock within 24 hours of admission was 39.6% (53/134), and 11 patients (8.21%) died in hospital; the in-hospital morbidity and mortality rate of patients in the shock group was higher than that in the non-shock group (20.8% vs. 0.0%, P<0.001). Symptoms of sphincter relaxation, coma, hypothermia, and organ function damage were more common in the shock group than in the non-shock group; and shock patients had longer hospitalization, ICU stay, and invasive ventilator use. Binary logistic regression analysis showed that the presence of sphincter relaxation manifestations ( OR=10.888, 95% CI: 1.677-70.684, P=0.012) was an independent risk factor for comorbid shock in patients with acute dichlorvos poisoning, and the use of cholinesterase reanimators ( OR=0.246, 95% CI: 0.072-0.846, P=0.026) was a protective factor for combined shock in patients with acute dichlorvos poisoning. Conclusions:The incidence of shock in patients with acute dichlorvos poisoning is high and affects the clinical prognosis, and the presence of sphincter relaxation and the absence of cholinesterase reenergizers are independent risk factors for combined shock in patients with acute dichlorvos poisoning.
RESUMEN
Objective:To investigate the status of the knowledge of cardiopulmonary resuscitation (CPR) in community medical staff, and analyze the factors influencing their levels of CPR knowledge and skills, and to provide a basis for improving community CPR training programs.Methods:From January to March 2022, we conducted a survey for the knowledge of CPR among community medical staff in Beijing through WeChat using a self-made questionnaire based on the 2016 National Consensus on Cardiopulmonary Resuscitation in China and the 2020 American Heart Association CPR guidelines. The questionnaire mainly focused on the basic information and CPR knowledge (full score, 17 points) and practice of medical workers. R4.0.3 software was used to perform multiple linear regression analysis.Results:A total of 990 medical personnel from 51 communities effectively responded to the survey. The mean CPR knowledge score was (10.27±2.87) points. The regression analysis showed that the CPR score was significantly lower in groups of male, non-31-40-year-olds, technical degrees, only 0-1 trainings in two years, not ever practicing CPR, and not ever using an automated external defibrillator (AED), suggesting that sex, age, educational attainment, training frequency, whether having the experience of CPR and AED practice or not were independent factors influencing the CPR score of community medical staff.Conclusions:The CPR competency of community medical staff needs to be improved, especially for those with technical degrees and non-31-40-year-olds. The training frequency should be increased based on the Ebbinghaus' forgetting curve, and stratified training is recommended for different populations. Those without practical experience should receive more CPR training with real-time feedback devices and high-fidelity simulation to improve their CPR skills.
RESUMEN
Objective:To understand the cognition and training status of basic life support among medical staff in Linfen, Shanxi Province, and to provide reference for the development of targeted training strategies and programs.Methods:A questionnaire survey was conducted among medical staff in 12 county hospitals in Linfen, Shanxi Province by convenience sampling method. The survey included the general characteristics of departments and medical staff, previous basic life support training assessment and cognitive status.Results:A total of 839 medical staff were included, 756 (90.1%) completed the survey, 183 (24.2%) were doctors and 573 (75.8%) were nurses. Most personnel lacked awareness of environmental safety, emergency response system start-up, adequate compression, airway management, and electrical defibrillation.Conclusions:The cognitive status of basic life support of medical staff in Linfen county is not optimistic. It is necessary to construct an applicable precision training course and retraining assessment system to improve the cognitive level and practical operation ability.
RESUMEN
Objective:To retrospectively analyze the establishment and implementation effect of ECPR rapid response medical team in emergency department, and to explore a more efficient rescue mode.Methods:A total of 41 patients who started ECPR in the emergency room of a tertiary hospital in Beijing from November 2017 to September 2022 were selected as subjects. The 14 patients treated by the ECPR rapid response medical team in the emergency department were set as the experimental group, and the 27 patients treated by the ECPR team of the MDT mode led by the cardiac surgeon were set as the control group. The ECPR start-up time, pipeline pre-filling time, ECPR start-up to ECMO successful operation time, complication rate and treatment success rate were compared between the two groups.Results:There was no significant difference in the outcome between the two groups (all P>0.05), but the total time (min) of ECPR implementation by the rapid response medical team in the emergency department was shorter (20.86 ± 10.86 vs. 23.04 ± 11.40), the incidence of complications was lower, and the success rate of treatment was higher (28.57 % vs. 25.93 %). Conclusion:Establishing a mature ECPR rapid response team dominated by emergency medical care helps improve the rescue coordination and work efficiency, thereby providing the emergency protection and management of full -chain for the treatment of critical condition.

RESUMEN
Objective:To investigate the current situation of telephone cardiopulmonary resuscitation (T-CPR) in China, and analyze the reasons for the low implementation rate of T-CPR.Methods:This was a multicenter cross-sectional survey. Twenty cities were selected from six geographical regions of China by convenient sampling method. Anonymous online electronic questionnaires were sent to emergency medical service staffs in each city. All respondents were divided into the routine T-CPR group and control group. Student's t test and Chi-square test were used to analyze the difference between groups. Multivariate logistic regression was used to analyze the influencing factors of T-CPR. Results:⑴A total of 1 191 questionnaires were collected. 80.94% of respondents knew T-CPR. Nine hundred and sixty respondents, who knew T-CPR and completed the questionnaires, were included in the study, and were divided into the routine T-CPR group ( n=401) and control group ( n=559). Nine hundred and thirty-nine (97.81%) responders believed that T-CPR should be implemented for cardiac arrest patients that could be confirmed by telephone.⑵Four hundred and one (41.77%) responders routinely implemented T-CPR. Among them, 237 (24.68%) responders always did and 164 (17.08%) responders often did. ⑶Multivariate logistic regression analysis showed that male ( OR=1.787, 95% CI: 1.235-2.587, P=0.002), age ( OR=1.025, 95% CI: 1.004-1.047, P=0.020), clinical medicine background ( OR=2.926, 95% CI: 1.387-6.171, P =0.005), dispatcher ( OR=5.305, 95% CI: 3.463-8.126, P<0.01), using medical priority dispatch system (MPDS) system ( OR=1.941, 95% CI: 1.418-2.656, P<0.01), and T-CPR policy or procedure ( OR=3.879, 95% CI: 2.652-5.674, P<0.01) were favorable factors for T-CPR. ⑷The top three reasons for implementing T-CPR in the routine T-CPR group were that they had received T-CPR training (67.08%), believed that T-CPR could improve survival rate (63.59%), and had standard T-CPR process (63.09%). The top three reasons for not implementing T-CPR in the control group were that worrying about bystander compliance (42.04%), worrying about the quality of bystander cardiopulmonary resuscitation (CPR) (38.28%), and worrying about medical dispute (36.14%). Conclusions:The awareness and implementation of T-CPR among emergency medical service staffs need to be improved. The implementation of T-CPR depend on telephone dispatchers with clinical medicine background, clear T-CPR policy, standardized operation procedure, and professional assistant tools. To improve the public's awareness of cardiac arrest and cardiopulmonary resuscitation, and to improve the supporting legal system are also conducive to the implementation of T-CPR.
RESUMEN
Objective:At present, the postgraduate education of emergency medicine in China mainly relies on the internal medicine system and lacks specialty pertinence. The purpose of this study is to establish a compulsory curriculum system for professional postgraduates of emergency medicine.Methods:Modified Delphi method was used to subscribe questionnaires to experts, and the contents were mainly about medical education management and research of emergency in the affiliated teaching hospitals of Peking University. Microsoft Excel 2016 was used for double entry of questionnaire contents, and SPSS 22.0 software was used for statistics.Results:The panel was consisted of 14 experts in total and two rounds of Delphi questionnaires were completed. The response rate of the two rounds were both 100%. The authority coefficient of experts was > 0.9 and the average score of each evaluation index was 4.07-5.00 points. The coefficient of variation of each index was 0-0.22 and the Kendall coefficient of concordance was 0.07-0.10.Conclusion:As a result, a comprehensive emergency professional postgraduate curriculum system has been established.
RESUMEN
Cardiopulmonary resuscitation is an important part of standardized residency training. There are certain flaws in the various commonly used training and assessment mode. In the exploration of the new mode, "step-by-step" training helps to learn skills step by step. "Low intensity and high frequency" training not only focuses on key points and difficulties, and lightens the burden of the teachers and residents, but also can improve the training effect through repeated reinforcement. Combining different training methods organically to establish a "diversified" training mode can make full use of the advantages of different methods and make up for each other's shortcomings. In addition, the "veto power" should be introduced into the assessment. Scenario simulation with role play may be an effective way to train teamwork ability, but it still needs further exploration.
RESUMEN
BackgroundWith the spread of COVID-19 from Wuhan, Hubei Province to other areas of the country, medical staff in Fever Clinics faced the challenge of identifying suspected cases among febrile patients with acute respiratory infections. We aimed to describe the prevalence and clinical features of COVID-19 as compared to pneumonias of other etiologies in a Fever Clinic in Beijing. MethodsIn this single-center, retrospective study, 342 cases of pneumonia were diagnosed in Fever Clinic in Peking University Third Hospital between January 21 to February 15, 2020. From these patients, 88 were reviewed by panel discussion as possible or probable cases of COVID-19, and received 2019-nCoV detection by RT-PCR. COVID-19 was confirmed by positive 2019-nCoV in 19 cases, and by epidemiological, clinical and CT features in 2 cases (the COVID-19 Group, n=21), while the remaining 67 cases served as the non-COVID-19 group. Demographic and epidemiological data, symptoms, laboratory and lung CT findings were collected, and compared between the two groups. FindingsThe prevalence of COVID-19 in all pneumonia patients during the study period was 6.14% (21/342). Compared with the non-COVID-19 group, more patients with COVID-19 had an identified epidemiological history (90.5% versus 32.8%, P<0.001). The COVID-19 group had lower WBC [5.19x109/L ({+/-}1.47) versus 7.21x109/L ({+/-}2.94), P<0.001] and neutrophil counts [3.39x109/L ({+/-}1.48) versus 5.38x109/L ({+/-}2.85), P<0.001] in peripheral blood. However, the count of lymphocytes was not different. On lung CT scans, involvement of 4 or more lobes was more common in the COVID-19 group (45% versus 16.4%, P=0.008). InterpretationIn the period of COVID-19 epidemic outside Hubei Province, the prevalence of COVID-19 in patients with pneumonia visiting our Fever Clinic in Beijing was 6.14%. Epidemiological evidence was important for prompt case finding, and lower blood WBC and neutrophil counts may be useful for differentiation from pneumonia of other etiologies. FundingNone.
RESUMEN
Objective:To propose the concept of a novel regional control and prevention (RCP) system for the outbreak of COVID-19 infectious disease, design an emergency epidemic prevention information system based on the existing network architecture and information system in the region, and a remote intelligent medical consultation and remote office platform, research and develop the technology of risk assessment and early warning for people in the region, and improve the regions’prevention and control ability facing emergency of major infectious diseases.Methods:Taking colleges, affiliated (teaching) hospitals, and cloud applications as typical RCP regional units, the existing local area network interaction methods between the cloud and universities and affiliated (teaching) hospitals are established to realize remote work in the network environment, remote medical imaging, psychological and ethical consultation and interaction; applying multi-agent propagation model based on complex network, combining Global Positioning System (GPS), Radio Frequency Identification (RFID), and electronic fence technology, to realize the risk classification and early warning of units and personnel in the area.Results:In the RCP, a system architecture combining campus network, affiliated (teaching) hospital intranet, and the Internet is used. Dynamic connection is made using distributed technology and cloud storage. The data buffer mechanism of the intermediary database in the network realized telemedicine consultation and telecommuting. Relying on the platform, multi-agent propagation model based on complex network and cellular automaton model are used to realize the score and early warning of population exposure risk in the region by using GPS, RFID and electronic fence technology.Conclusions:In the epidemic phase of major infectious diseases, the construction of RCP can improve the response speed of wartime epidemic prevention, provide reasonable data-based warnings and risk ratings, and reduce the exposure risk of susceptible people. The design and development of RCP is a systematic project that needs to combine regional structural and functional characteristics, and the foundation of the early informatization work in the region and the level of the emergency development team determine the development progress, maintenance, and actual application effects. It is recommended to establish a peacetime and wartime combined RCP mode and incorporate it into the government's disease control system to improve the national and regional level of prevention and control of major infectious diseases.

Objectives To investigate the cognition of dispatcher-initiated telephone cardiopulmonary resuscitation (TCPR) among emergency medical system(EMS) personnel and compare the cognition of TCPR among EMS personnel in different economic status,and to understand the current situation of TCPR cognition of EMS personnel in China.Methods This study is a multicenter crosssectional survey.The method of multi-level convenient sampling was adopted,and the test reliability and split half reliability of the questionnaire was tested.Questionnaire survey and data collection were conducted from December 2018 to June 2019.The ethical approval number is M2018264.SPSS 20.0 was used for analysis.x2 test was used to analyze the differences between groups.Results A total of 1191 electronic questionnaires were collected.Of them,80.94％ respondents knew TCPR,97.82％ respondents thought that TCPR should be implemented in cardiac arrest,36.62％ respondents thought that bystander cardiopulmonary resuscitation quality monitoring was needed in TCPR,and TCPR training courses were set up in the emergency department which recruited 25.83％ respondents.Emergency personnel in developed areas had a better understanding of the criteria for judging patients' breathlessness (11.69％ vs 7.89％,P=0.048),of TCPR need ncluding guidance of chest compression (92.45％ vs 87.49％,P=0.012) and of bystander cardiopulmonary resuscitation (BCPR) quality monitoring including the frequency of artificial respiration (84.42％ vs 74.87％,P=0.029) than those in underdeveloped areas,but there was no significant difference in other indicators (P＞0.05).Conclusions TCPR knowledge of EMS personnel in China is unsatisfactory.Further training is needed to improve their understanding of the criteria for judging cardiac arrest in out-of-hospital cardiac arrest patients via telephone,TCPR content and bystander cardiopulmonary resuscitation quality monitoring.There is difference in TCPR knowledge between the EMS personnel in developed and undeveloped areas in China.
RESUMEN
Objective To explore the influence of medical care reform on crowded emergency department in the tertiary hospital.Methods The 8 April 2017 was considered as turning point when Beijing began to implement medical care reform.The research subgroups consisted of pre-medical reform group,intra-medical reform group and post-medical reform group,according to the date 20 days before the medical reform,20 days after the medical reform and 21-40 days after the medical reform.During this period,The NEDOCS scores(The National Emergency Department Overcrowding Scale) were calculated at 10:00,14:00,18:00 in the Emergency Department of Peking University Third Hospital every day,the mean of which assessed the degree of crowding.The key indicators in the NEDOCS scoring formula were compared to find the reasons for the change of emergency crowding.All statistical analyses were performed using SPSS version 25.0.Continuous data presented as means ± standard deviation (normal distribution),analyzed by t-tests or median ± quartile(abnormal distribution),analyzed by Mann-Whitney U test.Results The NEDOCS scores in the intra-medical reform group were statistically higher than that in the pre-medical reform group (401.69 vs 339.68,P＜0.05).The NEDOCS scores in the post-medical reform group were higher than that in the pre-medical reform group,but the difference was not statistically significant (380.83 vs 339.68,P＞0.05).The number of ventilated patients (Rn) significantly increased after the reform (P＜0.05).Conclusions The degree of emergency department crowding in the tertiary hospital has increased after the Beijing medical care reform in 2017.The increase in the number of critically ill patients may be the reason for the increased overcrowding in the emergency department.
RESUMEN
The standard training of emergency residents is still in its early phase. Computer-based simulation teaching overcomes the drawbacks of traditional teaching mode, because of its high reducibility, simple operation , repeatability , low risks and feasibility for standardized assessment , which is the development trend of emergency medicine teaching. But at present, there are many deficiencies in the application and research of simulation teaching, including low popularity, low level of application, neglect of Teachers' training , research lagged behind , etc . In the future , these aspects should be continuously improved , including popularizing the understanding of computer simulation teaching and attaching importance to teachers' training and research work, so that simulation teaching procedures could meet the needs of modern medical development and practical clinical work.
RESUMEN
It has been 10 years since the residency training in China has been gradually implemented and standardized. Orientation is playing an important role in the transition from medical students to residents in a new work environment to ensure medical safety. The daily work of the emergency room is characterized by high intensity, fast pace and high risk. Orientation is even more important here. This article compared the similarities and differences between orientation program of emergency medicine in China and the United States, it was found that the orientation programs in the United States usually lasted for a longer time, the training was various in forms and the contents were more comprehensive. A multi-dimensional evaluation was designed for orientation also. It is worth summarizing and drawing lessons to provide reference for improving the orientation of emergency residents in China.
RESUMEN
The emergency management training for general practitioners during job-transfer training is an important part of clinical teaching. At present, there are many problems in emergency management teaching, such as teaching contents are extensive but the class hours are limited, traditional teaching cannot meet students' needs for studying and lack of practice for emergency management skills, leading to poor teaching effects. In the teaching of emergency management of general practitioners during job-transfer training, we cultivated emergency management ability by elaborating teaching content, strengthening their clinical thinking of emergency management, carrying out a variety of training models, enhancing skill training, and stressing the evaluation of performance and so on.

RESUMEN
Now the visiting physicians are usually trained without effective supervision and guidance mechanism.Since 2017,the Emergency Department of Peking University Third Hospital has adopted the training model under tutor system for visiting physicians.Tutors and visiting physicians are matched 1∶1.Personalized training program is made by tutors and visiting physicians depending on the level of the hospital where visiting physicians practice in,educational background,clinical experience,length and the goal of study.The training plan is refined according to the timeline in order to facilitate the tutor and training physician's own precise management.Since implementation of this training model,the visiting physicians say they are more efficient to complete the training program and learned more than before.The teaching ability of tutors has further been enhanced.
RESUMEN
Objective To evaluate the status of implementation of the chain of survival and the gap between the guideline's recommendations and clinical practice as well as to analyze the factors influencing the prognosis of cardiac arrest (CA) patients.Methods A retrospective analysis of CA in adult patients admitted to Emergency Department of Peking University Third Hospital from January 2012 to December 2013 was carried out.The epidemiology,clinical features,implementations of the chain of survival and outcome were compared between out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) patients,with regard to the analysis of the predictors for survival and neurological outcome.Results A total of 414 patients with 69.8％ male and average age of (61.7 ± 18.0) years were divided into two groups,OHCA group (n =190) and IHCA group (n =224).Cardiogenic cause was found in 30％ of CA patients.There were 27.5％ patients with restoration of spontaneous circulation (ROSC),8.2％ patients discharged in survival and 3.1％ patients with good neurologic outcome (CPC =1 and 2).There were higher proportion of medical responders arriving to CA patients within 5 minutes after onset (99.1％ vs.10.5％,P ＜0.01),bystander carrying out cardiopulmonary resuscitation (100％ vs.15.3％,P ＜0.01),CPR initiated in 5 minutes (98.7％ vs.11.1％,P ＜ 0.01),defibrillation performed in 5 minutes (87.5％ vs.12.5％,P ＜ 0.01) in IHCA group compared with OHCA.There were no statistical differences in epinephrine administration and epinephrine dose,and targeted temperature management between two groups.There were higher proportion of ROSC (37.1％ vs.16.3％,P ＜ 0.05),higher percentage of survivals discharged (31.0％ vs.22.6％,P =0.002) and good neurologic outcome with CPC =1 or 2 (48.1％ vs.0.0％,P =0.029) in IHCA group compared with OHCA.Location of CA occurred and initial arrhythmia rectifiable with defibrillation treatment after ROSC were the favorable predictors for assessing the percentages of ROSC and survivals discharged.In contrast,male and age over 65 years were the unfavorable predictors of ROSC.Conclusions Improvement in outcome of victims with CA is required in every link of the chain of survival,especially in prehospital rescue act,bystander carrying out CPR,defibrillation,and therapeutic hypothermia in unconscious patients after resuscitation.The effective implementation of chain of survival concept can improve the prognosis of CA patients.
