Abstract:
Objective:Based on the real-world clinical data of hospital electronic medical records, to analyze the length of stay and healthcare costs associated with in-hospital falls and fall injuries in hospitals.Methods:Based on the electronic medical record system of the First Affiliated Hospital of Nanjing Medical University, a retrospective cohort study was conducted on patients admitted to these departments reported falls in nursing management information system from January 2017 to December 2019. A total of 38 481 patients from 74 units were enrolled in this study. The patients′ characteristics, falls, falls injury, and explore the length of hospital stay and bottom-up direct cost were analyzed.Results:A total of 243 cases (0.6%) fell and 154 cases (63.4%) were injured by falls from January 2017 to December 2019. Compared with non-fallers, the median length of stay of patients with falls was 19 days, which was significantly increased compared with 7 days of patients without falls ( Z=-15.18, P<0.05). The median hospitalization cost of patients with falls was 39 000 yuan, which was significantly higher than 16 300 yuan of patients without falls ( Z=-11.47, P<0.01). There was no statistical difference between non-injuried fallers and injuried fallers for length of stay and healthcare costs ( Z=-0.92, -0.64, P>0.05). Linear regression model analysis showed that gender, age, comorbidity, inpatient department unit, reason of hospitalization were significantly correlated with inpatient cost and length of stay ( F=280.05, 217.31, all P<0.05). Conclusions:Patients who have an in-hospital fall have significantly longer hospital stays and higher direct costs, mainly can be attributed to the fall itself, not the injury. Our findings have important financial implications for real world in light of optimal intervention strategies, resource allocation and economic evaluation of fall prevention.
