Comparison of epidemiologic features between upper and lower limb injuries and risk factors for intensive care unit admission in a university hospital affiliated with the National Trauma Registry of Iran

Patients with LEIs were older and suffered from more severe injuries. In addition, the age- and ISS-adjusted ICU admission and length of hospital stay were significantly higher in LEI patients. The chance of ICU admission was associated with age, cause of injury, ISS, and body region. The findings of this study can aid in the meticulous selection of ICU-candidate patients. In addition, the role of factors other than ISS and age in ICU admission and prolongation of hospitalization should be addressed by prospective studies.
