Abstract

Objective: To assess the safety of a single dose of parenteral ketorolac for analgesia management in geriatric emergency department (ED) patients. Methods: This was a retrospective study of all administrations of parenteral ketorolac to adults ≥65 years of age and matched controls. The primary outcome was the occurrence of any of the following adverse events within 30 days of the ED visit: gastrointestinal bleeding, intracranial bleeding, acute decompensated heart failure, acute coronary syndrome, dialysis, transfusion, and death. The secondary outcome was the occurrence of an increase in serum creatinine of ≥1.5 times baseline within 7 and 30 days of the ED visit. Results: There were 480 patients included in the final analysis, of which 120 received ketorolac (3: 1 matching). The primary outcome occurred in 14 of 360 patients who did not receive ketorolac and 2 of 120 ketorolac patients (3.9% vs 1.7%, p = 0.38; OR 2.39, 95% CI 0.54–10.66). There was no occurrence of dialysis or death in either group. The secondary outcome occurred in 1 of 13 and 1 of 23 ketorolac patients with both a baseline serum creatinine and a measure within 7 and 30 days, respectively, but did not occur in patients who did not receive ketorolac (7 days: 7.7% vs 0.0%, p = 0.29; 30 days: 4.4% vs 0.0%, p = 0.22). Conclusion: The use of single doses of parenteral ketorolac for analgesia management was not associated with an increased incidence of adverse cardiovascular, gastrointestinal, or renal adverse outcomes in a select group of older adults.
