Objective: To study the distribution characteristics of in-hospital death cases, explore the composition characteristics of death disease spectrum, and provide reference for hospital management. Methods: The first page information of inpatient death medical records from 2018 to 2022 in a tertiary hospital in Hubei Province was collected, and the main diagnoses were classified according to the International Classification of Diseases, Tenth Revision (ICD-10) standard for the cause of death. The t test and x² test were used to statistically analyze the distribution characteristics of the death cases in terms of gender, age group, season, cause of death, and other factors. Results: From 2018 to 2022, the total mortality rate in our hospital was 0.38%, the overall male-to-female death ratio was 2.04:1, and the overall average age at death was 65.89 years old; 65.87 years old for males and 65.91 years old for females. Most of the dead patients were over 60 years old, with the mortality rate in is the highest during the winters being the highest. The disease with the highest mortality rate of was circulatory system diseases. Conclusion: The professional, technical, and nursing skills of medical institutions, should be improved to reduce the in-hospital mortality rate.
