Background: The purpose of this study was to identify risk factors of mortality for geriatric patients who fell from ground level at home and had a normal physiological examination at the scene.
Methods: Patients aged 65 and above, who sustained a ground level fall (GLF) with normal scene Glasgow Coma Scale (GCS) score 15, systolic blood pressure (SBP) > 90 and <160 mmHg, heart rate ≥ 60 and ≤100 beats per minute) from the 2012-2014 National Trauma Data Bank (NTDB) data sets were included in the study. Patients' characteristics, existing comorbidities [history of smoking, chronic kidney disease (CKD), cerebrovascular accident (CVA), diabetes mellitus (DM), and hypertension (HTN) requiring medication], injury severity scores (ISS), American College of Surgeons' (ACS) trauma center designation level, and outcomes were examined for each case. Risks factors of mortality were identified using bivariate analysis and logistic regression modeling.
Results: A total of 40,800 patients satisfied the study inclusion criteria. The findings of the logistic regression model for mortality using the covariates age, sex, race, SBP, ISS, ACS trauma level, smoking status, CKD, CVA, DM, and HTN were associated with a higher risk of mortality (p < .05). The fitted model had an Area under the Curve (AUC) measure of 0.75.
Conclusion: Cases of geriatric patients who look normal after a fall from ground level at home can still be associated with higher risk of in-hospital death, particularly those who are older, male, have certain comorbidities. These higher-risk patients should be triaged to the hospital with proper evaluation and management.
