Abstract

Purpose

This investigation aimed to understand the epidemiological characteristics and hospitalization burden and its possible influencing factors of patients with different injury mechanisms.

Methods

All trauma patients admitted via the emergency department at a trauma center from November 1, 2020, to April 30, 2022, were identified. The hospitalization burden, including the number of hospitalizations, deaths and in-hospital mortality, length of stay (LOS), and medical costs, was calculated. Univariate and multivariate logistic regression models were used to analyze the factors influencing the hospitalization burden of trauma. The receiver-operating characteristic (ROC) curves were drawn to evaluate the predictive value of the multivariate model.

Results

16 485 trauma patients with 16 552 hospitalizations were included, with an in-hospital mortality rate of 1.269‰, median LOS of 7 days, and median hospitalization costs of 54 725.28 CNY. The median age was 52 years. 62.54% were hospitalized due to falls. The upper and lower extremities were the most common injury regions. There are differences between the demographic, injury, and hospitalization characteristics and factors influencing hospitalization burden across injury mechanisms, but there were also common influencing factors. Injury region, surgery, transfusion, and ICU treatment are influential factors for prolonged LOS. Age, injury region, surgery, and transfusion were influential factors for high hospitalization costs.

Conclusions

This study provided primary evidence on the hospitalization burden of trauma. Considering demographics, injury and hospitalization characteristics as additional discriminators could further intervene in LOS and medical costs. Targeted efforts to use more early prevention measures could potentially lower future hospitalization burden.
