Introduction: geriatric patients are associated with worse outcomes in trauma compared to younger patients. hyperglycemia has been shown to be assocaited with worse outcomes in trauma as well. we sought ot investigate the association of stress induced hyperglycemia with mortality in geriatric trauma patients.
Methods: after obtaining institutional review board approval, a retrosepective review of geriatric (65 years of age and older) trauma patients admitted to our trauma center between january 2023 and december 2024. data collected included demographics, injury severity, emergency department initial systolic blood pressure (SBP) and heart rate. initial blood glucose level, laboratory data, patient co morbidities, hospital length of stay and mortality. stress induced hyperglycemia was defined ablood glucose value above 120 mg/dL in the emergency department in a non diabetic geriatric trauma patient. blood glucose values were dividedinto three categories, <120, 121-150, 151-200 and >200.
Results: 522 nondiabetic geriatric trauma patients were admitted to our trauma center during the study period. there were 24 deaths. Multivariable logistic rgression analysis was conducted to evalaute the association of stress induced hyperglycemia and death. ISS (p<.001), hyperglycemia >200 (p=.003) and comorbidities (p=.043) were independently predictive of death, while age group (p=.136) and SBP (p=.64) were not.
Conclusion: stress induced hyperglycemia is an independent predictor of death in nondiabetic geriatric trauma patients.
