We aimed to explore the characteristics of age, disease and premature mortality among middle-aged inpatients.
Cross-sectional.
Data were gathered from the electronic medical records system of the hospitals between 2011 and 2020: a regional study.
A total of 151 320 patients, aged 45-59 years, underwent hospitalisation.
We analysed the characteristics of age and disease using the database from the electronic medical record system. Moreover, a binary logistic regression model was adopted to investigate the risk factors for premature mortality.
We identified 151 320 eligible inpatients, 53.0% of whom were female. The proportion of middle-aged inpatients increased alarmingly over a decade from 6.4% in 2011 to 28.3% in 2020. The incidence rate of inpatients aged 45 to 50 years increased perpendicularly, with its peak observed at the age of 50. The prevalence tended to decrease after the age of 50; however, it increased at the age of 59. Overall, cancer had the highest incidence rate (22.7%), followed by accidental injury, digestive system disease, cardiovascular disease and cerebrovascular disease (9.0%, 7.9%, 6.3% and 4.5%, respectively). The overall mortality among the middle-aged inpatients was 0.5%. Logistic regression analysis showed that sex, marital status and comorbidity were the factors contributing to mortality in hospitalised patients, with male, divorced and more than two comorbidities being risk factors for death.
A rising trend in the number of middle-aged inpatients was observed during the study period. The number of hospitalisations reaches its peak at the age of 50. Being male, divorced and having more than two comorbidities are risk factors for premature mortality. So prevention, early detection and appropriate treatment of comorbidities are beneficial in improving health and reducing mortality.
我们旨在探讨中年住院患者的年龄、疾病及过早死亡特征。
横断面研究。
数据收集自2011年至2020年各医院的电子病历系统：一项区域研究。
共有151320名年龄在45至59岁之间的患者接受了住院治疗。
我们使用电子病历系统数据库分析年龄和疾病特征。此外，采用二元逻辑回归模型研究过早死亡的危险因素。
我们确定了151320名符合条件的住院患者，其中53.0%为女性。中年住院患者的比例在十年间惊人地上升，从2011年的6.4%升至2020年的28.3%。45至50岁住院患者的发病率呈垂直上升趋势，在50岁时达到峰值。患病率在50岁后趋于下降；然而，在59岁时有所上升。总体而言，癌症发病率最高（22.7%），其次是意外伤害、消化系统疾病、心血管疾病和脑血管疾病（分别为9.0%、7.9%、6.3%和4.5%）。中年住院患者的总体死亡率为0.5%。逻辑回归分析表明，性别、婚姻状况和合并症是导致住院患者死亡的因素，男性、离异及合并症超过两种是死亡的危险因素。
在研究期间观察到中年住院患者数量呈上升趋势。住院人数在50岁时达到峰值。男性、离异及合并症超过两种是过早死亡的危险因素。因此，合并症的预防、早期发现和适当治疗有助于改善健康状况并降低死亡率。
