another study (published 8d ago) looking at inappropriate medication use among community dwelling elderly. More specifically, the authors analyzed the results of 19 retrospective studies using various iterations of Beers criteria (1991, 1997 & 2002), Zhan's derivation of Beers, HEDIS subset of Zhan, and other measures. Depending upon the measure applied, the prevalence of inappropriate medication use ranged from 11.5% to 62.5%. In other words, at least 1 in 10 community dwelling elderly had an unsafe (combination of) medication(s) in their regimen. And depending upon the criteria used, as many as 2 in 3 community dwelling elderly were at risk.
Nevertheless, the take home point is that clinicians need to be more aware of the medications that they (and their colleagues) prescribe. And you & I need to chat w/our parents and older family members and ask about what medications they're keeping in their medicine cabinet. Great way to strike up a conversation around the holiday dinner table!
