Impressed by Evidence-Based Solutions; Want to Know Medications are Safe
Study says elderly
patients only willing to take medications to prevent cardiovascular
disease if benefits far greater than risks
Feb. 28, 2011
Senior citizens think a little differently about health and medications
than younger people who are not so encumbered by chronic disease. A new
study finds these elderly patients also have views that differ with the
guidelines for medical care that are scientifically prepared to enhance
A new study,
for example, finds that older
people are willing to take medications for cardiovascular disease
prevention, but only if the benefits far outweighs the risk.
published online by the Archives of Internal Medicine, one of the
JAMA/Archives journals, notes that many elderly patients have multiple
risk factors for chronic disease and may not value the guidelines in the
same way as clinicians when they consider benefits and harms of

Terri R. Fried,
M.D., of Yale University School of Medicine, New Haven, Conn., and the
VA Connecticut Healthcare System, and colleagues examined the
willingness of older adults to take medications for primary
cardiovascular disease prevention according to benefits and harms.
For this study,
356 in-person interviews were performed with community-living senior
citizens (average age, 76). The participants were asked about their
willingness to take medication for primary prevention of heart attack

attack over the next five years, but with various types and severity of
adverse effects, including fatigue, dizziness, nausea and fuzzy or
participants (88 percent) indicated they would take the medication if it
had no adverse effects, providing an absolute benefit of six fewer
persons with heart attack out of 100, approximating the average risk
reduction of currently available medications.
"As the absolute
benefit offered by the medication increased, so did the proportion

large proportions (48 percent to 69 percent) were unwilling or uncertain
about taking medication with average benefit causing mild fatigue,
nausea, or fuzzy thinking, and only 3 percent would take medication with
adverse effects severe enough to affect functioning."
finding of this study was the large influence exerted by the presence of
adverse effects on older persons' decisions about whether to take a

medications to older persons need to place emphasis on both benefits and
harms," they conclude.

In the major scandal of 2015, Volkswagen cheated you and the world. They rigged diesel emission controls so you, nor regulators, would know how much pollution their cars were adding to our environment.
They were caught and have reserved $7.3 billion to help "make it right" with victims.
