Objective: This study aimed to determine the rate of readmission for trauma patients in ICUs, as well as the
factors that predict this outcome.
Methods: This retrospective cohort study was conducted at Emtiaz Hospital, a level I referral trauma center
(Shiraz, Iran). It analyzed the ICU readmission rates among trauma patients over three years. The required
data were extracted from the Iranian Intensive Care Registry (IICUR), which included patient demographics,
injury severity, physiological parameters, and clinical outcomes. Statistical analysis was performed using SPSS
version 25.0. Descriptive statistics and different statistical tests, such as T-tests, Mann-Whitney tests, Chisquare tests, and logistic binary regression test were utilized.
Results: Among the 5273 patients discharged from the ICU during the study period, 195 (3.7%) were readmitted
during the same hospitalization. Patients readmitted to the ICU had a significantly higher mean age (54.83±22.73
years) than those who were not readmitted (47.08 years, p<0.001). Lower Glasgow Coma Scale (GCS) scores
at admission and discharge were associated with ICU readmission, implying that neurological status and
readmission risk were correlated with each other. Furthermore, respiratory challenges were identified as the
leading cause of unexpected readmission, including respiratory failure, hypoxic respiratory failure, respiratory
distress, and respiratory infections such as pneumonia. Injury patterns analysis revealed a higher frequency of
poly-trauma and head and neck injuries among patients readmitted to the ICU.
Conclusion: This study underscored the importance of ICU readmission among trauma patients, with a high
readmission rate during the same hospitalization. By developing comprehensive guidelines and optimizing
discharge processes, healthcare providers could potentially mitigate ICU readmissions and associated
complications, ultimately enhancing patient outcomes and resource utilization in trauma ICU settings. This
research provided valuable insights to inform evidence-based practices and improve the quality of care delivery
for trauma patients in intensive care settings.
