Background: Older adults are susceptible to adverse effects from opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and benzodiazepines (BZDs). We investigated factors associated with the administration of elevated doses of these medications of interest to older adults (≥65 years old) in the emergency department (ED).
Patients and methods: ED records were queried for the administration of medications of interest to older adults at two academic medical center EDs over a 6-month period. Frequency of recommended versus elevated (“High doses” were defined as doses that ranged between 1.5 and 3 times higher than the recommended starting doses; “very high doses” were defined as higher than high doses) starting doses of medications, as determined by geriatric pharmacy/medicine guidelines and expert consensus, was compared by age groups (65–69, 70–74, 75–79, 80–84, and ≥85 years), gender, and hospital.
Results: There were 17896 visits representing 11374 unique patients >65 years of age (55.3% men, 44.7% women). A total of 3394 doses of medications of interest including 1678 high doses and 684 very high doses were administered to 1364 different patients. Administration of elevated doses of medications was more common than that of recommended doses. Focusing on opioids and BZDs, the 65–69-year age group was much more likely to receive very high doses (1481 and 412 doses, respectively) than the ≥85-year age groups (relative risk [RR] 5.52, 95% CI 2.56–11.90), mainly reflecting elevated opioid dosing (RR 8.28, 95% CI 3.69–18.57). Men were more likely than women to receive very high doses (RR 1.47, 95% CI 1.26–1.72), primarily due to BZDs (RR 2.12, 95% CI 2.07–2.16).
Conclusion: Administration of elevated doses of opioids and BZDs in the older population occurs frequently in the ED, especially to the 65–69-year age group and men. Further attention to potentially unsafe dosing of high-risk medications to older adults in the ED is warranted.
