Ketorolac is an effective analgesic but the potential for acute kidney injury (AKI) is concerning, particularly in geriatric “G-60 trauma” patients. The objectives of this study are to report the incidence of AKI in patients who receive ketorolac, identify risk factors for AKI, and develop a risk factor-guided algorithm for safe utilization. This retrospective cohort study included trauma patients age 60 years and older who received intravenous ketorolac. The primary endpoint was the incidence of AKI. Among 316 patients evaluated, the incidence of AKI was 2.5%. Patients with AKI received more nephrotoxins, had more comorbidities, and higher use of loop diuretics or vasopressors. Loop diuretic therapy and number of comorbidities were independent predictors of AKI. Risk for AKI with ketorolac was low, being more prevalent with comorbidities or receipt of loop diuretics.
