The problem of elderly people taking too many medications is not new, but continues to pose a serious risk to health as well as contribute significantly to rising Medicare costs. The fact is that nearly 20% of adults aged 65 years and older who are not hospitalized take 10 or more medications daily. This number is not the result of shoddy care, but rather achieved when doctors simply follow practice guidelines for several common, co-existing conditions like diabetes, high blood pressure and depression, for example. If you look at all seniors (those both in and out of the hospital) the American Society of Consultant Pharmacists reports that the average 65-69 year old takes nearly 14 prescriptions per year; by ages 80-84 that number averages an astounding 18 prescription drugs per year.
What’s troubling is that instead of improving the health of seniors, evidence is growing that the more medications an elderly person takes, the more likely he is to experience falls, cognitive decline, loss of mobility, depression and even cardiac problems. These adverse drug effects may be mistaken for Alzheimer’s disease or other dementias too. The bottom line: Experts estimate that up to one-third of the elderly in our communities may be over-medicated and some 20% of their hospital admissions are due to adverse drug events. The costs related to over-medication in the elderly are thought to exceed $80 billion each year.
