ObjectiveTo investigate the correlation of social support with general condition of hospitalization and outcome events (improvement, automatic discharge or death) in the hospitalized elderly people. Methods A total of 1 457 patients admitted in our geriatric department from January 2018 to January 2019 were enrolled in this study. The effects of household income per capita, living environment, family care situation, intimacy with family members, and other social support on the hospitalization times within recent 1 year, activities of daily living (Bathel ADL) and the outcome events (death or automatic discharge) were analyzed. SPSS statistics 22.0 was used to perform the statistical analysis. Spearman correlation analysis was employed for univariate correlation analysis, and logistic regression analysis for multivariate correlation analysis. Results Among the 1 457 patients, significant correlations were observed in age, household income per capita, Bathel ADL at admission, and number of underlying diseases with the hospitalization times in recent 1 year (r=0.47,0.49, -0.45,0.69, P<0.05). Logistic regression analysis showed that the hospitalization times in recent 1 year were correlated with age, household income per capita, and Bathel ADL (OR=2.73,2.15, 3.51, P<0.05). Age affected the patients′ Bathel ADL at admission (r=-0.62, P<0.05). The outcome events (death or automatic discharge) were related to age, household income per capita, intimacy with family members, Bathel ADL and number of underlying diseases (r=0.70, -0.17, 0.56,0.52,0.69, P<0.05). Logistic regression analysis indicated that the outcome events were correlated with household income per capita, intimacy with family members and Bathel ADL at admission (OR=4.22, 1.65, 4.81, P<0.05). Conclusion Age, household income per capita, and Bathel ADL at admission affect the hospitalization frequency and discharge outcome of patients. Improving the social economic level and strengthening the care for the elderly can improve the incidence of hospitalization related negative events.
