There is evidence that Beers' criteria of inappropriate medication use is associated with adverse healthcare impact in the community-dwelling elderly. With increasing use of Beers' criteria as quality-of-care measures, there is a need to strengthen the predictive validity of these criteria in all healthcare settings.
Inappropriate prescribing or use trends are noteworthy because they were observed despite methodologic differences. The findings can be instrumental in developing targeted interventions to influence future prescribing practices. More research is needed to address the national trends and healthcare impact of inappropriate drug use in the elderly.
Nearly one in five community-dwelling elderly persons used psychotropic medications, primarily antidepressants followed by antianxiety agents. Enabling and need factors were consistently associated with psychotropic classes examined, whereas most predisposing factors varied with the type of psychotropic drug class.
Nearly one-third of elderly nursing home residents with dementia received antipsychotic medications, mainly atypical agents. Predisposing, enabling and need factors influenced the use of atypical agents in dementia patients. These findings suggest a need to optimize use of atypical antipsychotics in elderly dementia patients in nursing homes in the light of recent efficacy and safety data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
