| Objective: To explore the characteristics of the emergency population,The distribution of the Diagnostic quantity at any time,and the impact of changes in meteorological factors and environmental pollution on the emergency department patients in a tertiary A general hospital in southern Anhui from July 01,2016 to June 01,2019.With a view to providing guidance for guiding the hospital to improve emergency management,resource allocation and coping strategies,it will further standardize emergency medicine and improve the environment for emergency treatment.Methods: By referring to the register records of emergency medical patients in the emergency hall of the hospital,the information(gender,age,residential address,treatment time,triage department,in-patient or not,in-patient department,main diagnosis)of emergency medical treatment of patients in A third-level general hospital in southern Anhui was collected from July 1,2016 to June 30,2019,and according to the inclusion and exclusion criteria,the data of patients who meet the standard vertebrae are entered into the Excel software to establish a database;the main indicators of meteorological and atmospheric pollutants in the area during the same period are collected.A retrospective analysis method and SPSS 22.0 statistical software were used to perform a descriptive statistical analysis of the characteristics of the emergency population and the time distribution characteristics of the number of people.List the corresponding charts and summarize their laws and related characteristics.The characteristics are described by (?)± s.Using the R language software,through the quasi-Poisson generalized addition model(GAMs)in time series analysis,a distributed lag nonlinear model(DLNM)is introduced into the model to establish the relationship between the number of emergency visits and meteorological elements and atmospheric pollutants.Control the confounding related factors,and explore the correlation between various meteorological elements,air pollutants and emergency treatment.Results:(1)From July 01,2016 to June 30,2019,a tertiary Class A general hospital in southern Anhui included a total of 54,982 patients admitted to the emergency medical department.The total emergency department visits showed a trend of first decrease and then increase.It mainly comes from the population living in this city and its suburbs.Among them,the male to female ratio is 1.23: 1.The elderly group of patients aged 65 and over is the main group of emergency patients,followed by the middle-aged group of patients aged 45-64,accounting for 41.90% and 34.29%,respectively.(2)In the disease spectrum,the top six people in the age group of 14 and older are trauma,nervous system disease,circulatory system disease,digestive system disease,respiratory disease,and physical and chemical factors,which account for all diseases.90.48% of the cases,the top six admitted to the department in turn are neurology,emergency medicine,neurosurgery,cardiovascular medicine,orthopedics,digestive medicine;groups under 14 years of age in turn are trauma,neurological diseases,diseases caused by physical and chemical factors,Respiratory diseases,respiratory circulatory failure and pre-hospital deaths,circulatory and digestive diseases account for 90.07% of all diseases in this group;the order of the disease spectrum of the total emergency department is the same as that of people aged 14 and over.Multiple injuries(73.54%)are the main causes of trauma patients;acute poisoning(92.78%)is the main cause of damage caused by physical and chemical factors;the top three acute poisoning types are alcohol poisoning(48.85%)and various drug poisonings.(Accounting for 21.71%),pesticide poisoning(accounting for 18.93%);pesticide poisoning was mainly caused by paraquat or diquat(76.34%).(3)In the time distribution of emergency patients,the peak period of 24 hours a day is 10: 00-11: 00 and 18: 00-20: 00,and the low peak period is 4: 00-6: 00;The number of consultations in July and August was relatively high,the lowest in April;the seasonal distribution was highest in summer,followed by winter and the lowest in spring.(4)Meteorological elements related to emergency department visits,main temperature of air pollutant indicators,PM10,NO2,O3,SO2,PM2.5;positive correlation with temperature,SO2,O3,and negative correlation with PM10,NO2,PM2.5 Related.(5)In the multi-pollutant model,after the introduction of NO2 and SO2 into the PM10 and PM2.5 models,the effect value ER decreased,suggesting that there is a certain synergy between them,and that particulate matter may be an independent risk factor for emergency department visits.Conclusion:(1)This study revealed the distribution of gender,age,place of residence,time of visit,type of disease and emergency department visits and meteorological factors in a third-level general hospital in southern Anhui from July 01,2016 to June 30,2019.The relationship of environmental pollutants.The characteristics of the emergency patient population are similar to those in other related studies in other regions,and there are some differences.According to the major groups,the age of high incidence,and the spectrum of specific diseases,rationally allocate medical resources,make breakthroughs in key points,and improve the efficiency of emergency medical care.(2)There is a specific time distribution pattern of emergency department visits.Analyzing the difference in the number of visits and high incidence in different time periods and seasons,effective prevention and response measures can effectively reduce the emergency department pressure and achieve a win-win situation for doctors and patients.(3)There are correlations between meteorological elements,multiple index elements in air pollutants,and emergency department visits.The effect value of temperature and PM10 on the emergency department visits is greater;there is a certain synergy before multiple pollutants,and particulate matter may Is an independent risk factor leading to emergency department visits.(4)There are differences in the groups of emergency treatments faced by hospitals in different regions,and the meteorological elements and environmental pollutant components are also different.Carrying out relevant epidemiological discussions of emergency treatments in specific regions will enable personalized medical development in the region Greatly benefit. |
