BACKGROUND: Trauma centers are confronted with rising numbers of geriatric trauma patients at high risk for adverse outcomes. Geriatric screening is advocated but not standardized within trauma centers. OBJECTIVE: This study aims to describe the impact of Identification of Seniors at Risk (ISAR) screening on patient outcomes and geriatric evaluations. METHODS: This study used a pre-/postdesign to assess the impact of ISAR screening on patient outcomes and geriatric evaluations in trauma patients 60 years and older, comparing the periods before (2014–2016) and after (2017–2019) screening implementation. RESULTS: Charts for 1,142 patients were reviewed. Comparing pre- to post-ISAR groups, the post-ISAR group with geriatric evaluations were older (M = 82.06, SD = 9.51 vs. M = 83.64, SD = 8.69; p = .026) with higher Injury Severity Scores (M = 9.22, SD = 0.69 vs. M = 9.38, SD = 0.92; p = .001). There was no significant difference in length of stay, intensive care unit length of stay, readmission rate, hospice consults, or inhospital mortality. Inhospital mortality (n = 8/380, 2.11% vs. n = 4/434, 0.92%) and length of stay in hours (M = 136.49, SD = 67.09 vs. M = 132.53, SD = 69.06) down-trended in the postgroup with geriatric evaluation. CONCLUSION: Resources and care coordination efforts can be directed toward specific geriatric screening scores to achieve optimal outcomes. Varying results were found related to outcomes of geriatric evaluations prompting future research.
