Patients were divided into four groups: high risk, moderate risk, low risk and no risk (GNRI: < 82, 82 to < 92, 92 to ≤ 98 and > 98) for patient demography, comorbidities, and adverse outcomes analysis.Results: After 1:1 propensity score-matched analysis, 97 patients in high-risk group, 144 patients in moderate-risk group, and 114 patients in low-risk group were compared to no risk group. High-risk group patients had a 5.7-fold higher risk of mortality (p = 0.003) and prolong hospital stay (18.0 vs 12.3 days; p = 0.016) when compared to no-risk group patients. Significantly prolong hospital stay were also found in low-risk and moderate-risk group when compared to no risk group.Conclusion: A lower GNRI is associated with prolonged hospital stay in the elderly patients with fall injuries. High nutritional risk (GNRI < 82) is associated with an increased in-hospital mortality rate.Keywords: Geriatric Nutritional Risk Index, elderly patients, fall injuries, trauma
