People don't like to take lots of medications,
especially prescription medications. They're expensive and inconvenient,
and they can cause side effects. To some people they just seem non-natural:
witness the huge popularity of alternative therapies such as manipulation
and acupuncture.
On the other hand, advances in drug therapy offer
both improved survival and a better quality of life for untold numbers
of Americans. Nowhere is this more evident than in the treatment
of the chronic disorders so common among older adults. Yet, many
people with such disorders are under-treated with medications, not
the other way around. In fact, for many of us the question for our
doctors should not be "Am I taking too many pills?", but
rather "Am I taking enough?" If this seems surprising
to you, consider just four examples.
Heart Failure
Heart failure is a weakened condition of the heart muscle resulting
from heart attack, hypertension or other factors. It is a serious
progressive disorder that causes fatigue and shortness of breath,
but in its early stages may be asymptomatic. It is the commonest
reason for hospital admission among people over 65. Until the 1980's,
the overall mortality rate at five years was about 60%. Then, in
the 1990's, it declined to 50%; for optimally treated patients it
has declined even further. The reason: newer and better drug treatments.
Today, the best treatment for heart failure requires
a combination of three, and sometimes four different classes of
medications: an ACE inhibitor, diuretic, beta blocker and sometimes
digoxin. The medications are important both for prolonging survival
and reducing disability.
Regrettably, most heart failure patients are not
getting the drugs they should have. Even the ACE inhibitors (Altace,
Prinivil, Vasotec, Monopril and others), whose life-saving benefits
have been known for over a decade, are still underutilized. Of patients
with early stage heart failure, as many as half are not receiving
these valuable drugs.
Diabetes
As many as 20% of people over 65 have diabetes. The better their
blood sugar is controlled, the lower their risk of complications
like blindness, kidney injury, amputation and heart attack. Current
recommendations call for bringing blood sugar levels to normal or
near-normal throughout the day.
Of course, diabetes care encompasses many different
interventions including diet, exercise, preventive care and treatment
of coexisting conditions. Nevertheless, achieving optimal blood
sugar levels almost always requires medication, with many patients
requiring combinations of two or more drugs.
How many diabetics are reaching optimal treatment
goals? Unfortunately, only a minority. In fact, the National Committee
on Quality Assurance found that about 40% of diabetics are under
manifestly poor control and therefore face serious complications
that could be prevented.
Hypertension
Hypertension (high blood pressure) is the most common primary diagnosis
in America. Almost all seniors either now have or will some day
develop hypertension. Lowering blood pressure has been shown to
reduce the incidence of stroke by 35-40%, heart attack by 25% and
heart failure by more than 50%.
Widely publicized evidence and expert consensus
calls for lowering blood pressure to less than 140/90 to achieve
the foregoing benefits, and this usually requires antihypertensive
drugs. In older adults a combination of two or more drugs is often
needed.
How many people with hypertension are receiving
treatment adequate to get their blood pressures below 140/90? The
answer is only about one out of three. The rest should be receiving
more aggressive treatment. Yes, weight loss, exercise and dietary
measures play an important role; but overall, Americans with hypertension
are still being grossly under-treated with medications.
Osteoporosis
Over ten million Americans, most of whom are women over 50, have
osteoporosis. They are at increased risk for debilitating fractures
that can threaten their independence, lead to serious disability
or even death. Yet about two-thirds of people with osteoporosis
don't even know they have it. Fully 85% aren't being treated.
Prevention is always best, and certainly measures
like regular exercise, getting adequate dietary calcium and avoidance
of smoking and excess alcohol are important. However, these measures
alone won't reverse osteoporosis once it is already established.
For that, one must take one or more of the several prescription
drugs approved for treating the disorder. Unfortunately, most seniors
who would benefit aren't getting them.
Too Many Pills or Too Few?
Examples like these aside, it is still a fact that many seniors
receive prescriptions for unnecessary or harmful drugs. Serious
and preventable adverse drug effects are all too common, and seniors
would be right to be cautious. But, for many chronic conditions
like those discussed above, critical medications are frequently
not prescribed enough. Therefore the next time you look skeptically
at your list of medications, don't just ask which ones you could
do without. Ask also whether you are getting enough of the ones
you need.
