I just returned from a thought-provoking conference at
Dartmouth. Entitled Preventing
Overdiagnosis: Winding Back the Harms of Too Much Care, and co-sponsored by
Dartmouth University, British Medical Journal, Consumer Reports, and
Australia’s Bond University, the conference raised many points that are rarely
discussed.
Here are some of my favorite quotes:
“Risk factors have
been turned into diseases.” Dr. Steve Woloshin discussed the absurdity of
labeling us all with a “pre-disease”: doesn’t everyone all have some version of
pre-hypertension, pre-diabetes, or even pre-death? More insidious is the promulgation
of testing people who have no symptoms, despite of evidence of harm. American
Cancer Society’s Chief Medical Officer Dr. Otis Brawley discussed how hospitals
offer “free” screening tests knowing that they will lead to false
positives, thus creating a market for more testing and more care.
“Diseases are being
created for the purpose of selling medications.” Dr. Lisa Schwartz told the
story of how GlaxoSmithKline created
a new disease entity—restless leg syndrome—to find a new use of a
Parkinson’s disease medication that was about to go off patent. Roy Moynihan
showed his class spoof video
of a new and dangerous epidemic.
“Ordinary experience
is medicalized.” Dr. Allen Frances, a psychiatrist and Chair of the DSM4
task force, rails
against the psychiatric profession for labeling people with diseases they
don’t have. If you are grieving two weeks after the death of a spouse, you have
depressive disorder; if your child is inquisitive and energetic, he has
attention deficit disorder. Of course, watchful waiting is never the solution,
but fortunately, there is a new and expensive medication for this disease.
“Language corrupts
thought.” A diagnosis of “carcinoma-in-situ” brings up scary connotations
and fuels the desire for aggressive treatment. However, our technologies have
gotten so advanced that we are detecting many early cancers that, if left
alone, may never grow or harm the patient. The National Cancer Institute
recently proposed a change in
terminology for cancer, and other conference speakers proposed other disease
definitions that should be changed.
“We are practicing
faith-based medicine that ignores the harms and exaggerates the benefits.”
It is well-documented that medical journals
bias in favor of positive results, and that there are many financial
interests to promote the newest, latest medication or treatment. Stories abound
about people who survived because of early detection of disease and new, experimental
treatment. However, there are also many stories of people who experience
serious side effects and fatalities from overdiagnosis
and overtreatment.
These counternarratives need to be told, and evidence for harm needs to be
published.
“Overdiagnosis is a
symptom of the same problem that drives underdiagnosis and misdiagnosis.”
In the discussion of overdiagnosis, it’s important not to forget that there are
other pressing issues too, including medical error and lack of access to
healthcare. The medical industrial complex is at fault here, too, and doctors
need to assume our social
responsibility and moral imperative to do what’s best for our patients.
“More care isn’t
better care; it’s just more care.” In the words of my hero, cardiologist
and Nobel Peace Prize winner Dr. Bernard Lown: “Overtreatment harms patients, thereby negating the first
principle of doctoring, primum non nocere.” Our goal in
medicine should be to do “as much as possible for the patient, as little as possible to the patient.”
There will be many challenges ahead for conference
attendees, including the difficulty of framing and discussing the problems of
overdiagnosis and overtreatment. Much of this conversation will continue at the Lown Institute's Right Care Alliance conference in December. My next few blog articles will address these
difficulties. Stay tuned, and please feel free to contribute your thoughts
