Analysis On Clinical Features Of 8670 Dead Patients Of The Affiliated Hospital Of Southwest Medical University During The Last Fifteen Years

Objective: Along with the propelled social and medical and health care reform process in our country,spectrum of disease of residents in our country had also changed,and the total mortality of hospitalized patients had gradually decreased.To investigate the distribution of disease and the rule of death cause,by analyzing the medical records of 8670 died patients in-hospital of the affiliated hospital of Southwest Medical University(previously named the affiliated hospital of Luzhou Medical college)during January 1,2000-December 31,2014.Methods:By use of hospital information department medical record query system,we searched the number of discharge patients,total number and medical record number of died patients of the affiliated hospital of Southwest Medical University during January 1,2000-December 31,2014.We read the death patients hospitalized cases one by one.We conducted statistical analysis to the factors of died patients' mortality,cause of death,gender composition,combinations and complications,whether surgery,and so on,by use of excel 2007 and SPSS17.0software.Results:1.Death and gender: There were 8670 died cases in 15 years,which contained 5701 male cases and 2969 female cases,sex ratio of 1.92:1(P<0.05).2.Seasonal distribution: The highest died cases were in winter,which was 2362.The less died cases were in spring,which was 2152.3.Month distribution: The highest died cases were in January,which were 827.The least died cases were in Jun,which was 634.4.Distribution of length of stay: The total length of stay was 85670 day in 15 years.Minimum duration was 1 day.Maximum duration was 342 day.Average stay was 9.88 day.The maximum number of died patient in 1 day was 2625 after being hospitalized,accounting for 30.28%.5.Distribution of age brackets: The total number of died patient was 901 in age bracket of 0~4,239 in age bracket of 5~14,1489 in age bracket of 15-44,1760 in age bracket of 45-59,and 4281 in age bracket of more than 60 which was maximum and account for a half of total.The death toll in age bracket of 45-59 and more than 60 account for 70% of total.6.Variation tendency of fatality rate: The number of hospitalized patients increased rapidly in 15 years,but the inpatient mortality declined year by year.7.The main rank order of causes of death and distribution: Circulatory system disease,respiratory system disease,malignant tumor,injury and poisoning,and digestive system disease were the top five cause of death.2317 cases died for circulation system,which accounted for 26.72%,the ratio of 1.51:1.The top three causes of death in circulation system were coronary heart disease,cerebral hemorrhage,cerebral infarction,which number were 518,445,321,respectively.The top three causes of death in cardiovascular system disease were coronaryheart disease,high blood pressure,congenital heart disease,which number were518,304,149,respectively.1300 cases died for respiratory system,which accounted for 14.99%,the ratio of 2.55:1.The top three causes of death in respiratory system were pneumonia,chronic obstructive pulmonary disease,respiratory failure,which number were 454,404,217,respectively.1269 cases died for malignant tumor,which accounted for 14.64%,the ratio of 2.50:1.The top three causes of death in respiratory system were Lung cancer,leukemia,liver cancer,which number were 350,231,186,respectively.8.Analysis on Clinical features of 1186 patients died for heart disease: There were 1186 patients died for heart disease,which contained 662 male cases and 506 female cases,sex ratio of 1.30:1.The number of died for heart disease were mostly in Spring and Winter,which accounted for more than half patients died for circulatory system.518 cases died for coronary heart disease,which was the main death cause of heart disease and accounted for 44.35%.150 cases died for acute myocardial infarction,which accounted for 12.84%.The death toll in age bracket of 45-59 and more than 60 accounted for 77.40% of total patients died for heart disease.The death toll died for PCI postoperative complications were32,which accounted for 2.7% in died patient in-hospital.The death toll died for valve repair postoperative complications were 56,which accounted for4.79%.Conclusions: 1.Fatality rate of inpatient of the affiliated hospital of Southwest Medical University was decreased obviously in 15 years.2.Big changes have taken place in hospitalized patients' death spectrum.Circulatorysystem disease was for the first cause of death,respiratory system disease second,malignant tumor third.The rank order of causes of death decreased in digestive system diseases.3.Death toll and composition ratio of inpatient changed along with the age,gender,season,and length of stay.The death toll in age bracket of 45-59 and more than 60 account for 70% of total.In the death of all diseases,female mortality in rheumatic and endocrine system disease was higher than male,however,male mortality in rest diseases higher than female.Deaths in Winter and Spring were significantly higher than Summer and Fall.The shorter the time to be admitted to hospital,the higher the deaths.4.Circulatory system diseases and respiratory system disease were the major cause of death in hospitalized patients.The top five causes of death exceeded more than 75% of total deaths.
