ARTICLE HIGHLIGHTS
Research background

With the aging world population the incidence of falls has intensified and hospitalization costs are increasing. Falls are one type of event studied in the health economics of patient safety.

Research motivation

Many developed countries have conducted research on fall-related hospitalization costs. However, China, a developing country, still lacks large-sample studies.

Research objectives

The aim of the study was to investigate the composition and factors related to the hospitalization costs of fall-related injuries in elderly inpatients and establish factor-based, cost-related groupings to provide a basis for the rational economic control of hospitalization costs.

Research methods

Quantile regression (QR) analysis was used to identify the factors related to fall-related hospitalization costs. A decision tree model based on the chi-squared automatic interaction detector algorithm for hospitalization cost grouping was built by setting the factors in the regression results as separation nodes.

Research results

The total hospitalization cost of fall-related injuries in the elderly patients investigated was 180479203.03 RMB. The cost grouping model was established based on the QR results, and patient age, length of stay, operation type, wound position and wound type were the most important influencing factors in the model.

Research conclusions

Our grouping model of hospitalization costs clearly reflects the key factors affecting hospitalization costs and is meaningful for strengthening the reasonable control of these costs.

Research perspectives

This was a retrospective study; hence, a prospective large-scale multicenter study is still required.
