“…However, in our study, this associationcouldnot be established due to the smallnumberof narrow therapeutic index drug-related preventable ADEs. 35 An interesting finding of this study was that more serious ADEs/PADEs were deemed to be preventable, although the difference was not statistically significant. A US study confined to older outpatientsfound a similar association betweenseverity and preventability of ADES.…”

“…This finding is in agreement with a similar ED-based study in Spain, which reported that the preventability of ADEs was related to drugs with a narrow therapeutic index. 25 Therefore, it would be better to consider not only the prescribed medications for the elderly group but also the follow-up of these patients for medication monitoring as a strategy for preventing ADEs.…”

To compare the proportion, seriousness, preventability of adverse drug events (ADEs) between the older adults (≥65 years old) and younger adults (<65 years old) presenting to the emergency department (ED), we conducted a prospective observational cohort study of patients 18 years and older presenting to the ED. For all ED visits between March 1, 2009, and Feb 28, 2010, investigators identified ADEs and assessed cases using the Naranjo adverse drug reaction probability scale. Outcomes (proportion, seriousness, and preventability of ADE, length of ED stay, and hospitalization) and associated variables were measured and compared between younger and older adults. The results showed that of 58, 569 ED visits, 295 older adults, and 157 younger adults were diagnosed as having an ADE and included in our analysis. The proportion of ADEs leading to ED visits in the older group, 14.3 per 1000 (295/20,628), was significantly higher than the younger group of 4.1 per 1000 (157/37,941).The older group with ADE had a longer ED stay (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.9–6.4 for stay ≥ 24 hours) and larger proportion of preventable ADEs (OR 2.2, 95% CI 1.4–3.6) than the younger group, but there was no significant difference in terms of serious ADEs (OR 0.6, 95% CI 0.3–1.3 for fatal and life threatening) and hospitalization (OR 1.5, 95% CI 0.9–2.6) between the 2 groups. In addition, patients in the older group were more likely to be male, to have symptoms of fatigue or altered mental status, to involve cardiovascular, renal, and respiratory systems, and to have higher Charlson comorbidity index scores, higher number of prescription medications, and higher proportion of unintentional overdose. In conclusion, the proportion of ADE-related ED visits in older adults was higher than younger adults, and many of these were preventable. The most common drug categories associated with preventable ADEs in the older adults were antithrombotic agents, antidiabetic agents, and cardiovascular agents.

“…Classification of FADEs included both the World Health Organisation’s definition of ADRs: a response to a drug which is noxious and unintended, and which occurs at doses normally used in man for the prophylaxis, diagnosis or therapy of disease, or for the modification of physiological function [1], as well as ADEs related to, e.g. intoxications and inappropriate prescribing or administered drugs [3, 4, 9, 10]. Identification of ADRs/ADEs was based on known drug actions and interactions as described in the literature and drug monographs.…”
