Abstract：Objective To investigate the number of disease-involved systems of elders and its influence on death for inpatients. Methods According to the international statistical classification of diseases and related health problems (ICD-10), the disease-involved systems of elderly inpatients in a hospital in Guangdong Province were classified. Logistic regression was used to analyze the influence of number of disease-involved systems on death and roc curve was used to analyze its predictive value for the death of inpatients. Results The proportion of diseases involving two or more systems and four or more systems in the hospitalized elders were 76.80% and 30.05% respectively. The proportion of diseases involving 5 or more systems was 20.87% in males, which was statistically higher than that in females (15.30%) (Ｐ<0.05). The more number of disease-related systems, the greater the risk of death for older patients (OR=1.471). After adjusting for the effects of age, sex, hospitalization days, transfer section, route of admission, source of patient, operation, combined operation, and case classification, the risk of death for patients would increase 21.00% when number of disease-related systems added one. Number of disease-involved systems had certain predictive value for death of elders in the hospital, with area under roc curve was 0.734 (95% CI: 0.711-0.758). Conclusion Number of disease-related systems was an independent risk factor for hospitalized elders (≥60 years), which suggested that close attention to the number of disease-related systems should be paid and multi-disciplinary codiagnosis and treatment model needed to be established in order to maintain the health status of elders.
