Defensive Medicine
July 18th, 2009
After a week of speaking on health care, I have to elucidate a question which continually arises, but upon which I don’t address.
Is the cost of health care in the U.S. so high because of malpractice and therefore wouldn’t costs decrease if we had tort reform.
For all industries in the U.S., costs are increased because of litigation or fear of litigation. At the same token, our legal system has kept some really bad actors more honest and compensated some who were gravely injured. We need a healthy legal system, not a lottery within the courts.
Rising costs of malpractice insurance do add to the cost of health care primarily for physicians and hospitals. But this cost is not a primary factor in escalating prices. More than the actual premiums paid, which is readily accountable, is the intangible cost of practicing defensive medicine.
What exactly is defensive medicine???
This is the practice wherein a provider may order tests, blood work, imaging studies, invasive procedures or more office visits to solidify a diagnosis or increase the likelihood of a desirable outcome. In general, the less education a provider has, the more tests may be ordered (except if you are House M.D.). It may additionally pit providers against one another.
At the AMA meeting, I recently encountered 2 family doctors discussing the validity of a CAT scan in the diagnosis of appendicitis. When I was a nurse we never did a CAT scan, and yes some individuals did get an appendectomy and later find that they did not have appendicitis. The doctors comment however, was that the surgeon “only wants to operate” so surgeons don’t care about getting CAT scans to cement the correct diagnosis.
I interjected a conservation I had had last year on campaign trail. A well-to-d0 businessman was upset that he had to pay $1000 for a CAT scan when his daughter had appendicitis. The ER doctor said she had it, the surgeon and nurses were fairly certain by her symptoms, physical signs and elevated white blood count indicating infection, but the surgeon ordered a CAT scan.
The scan, of course, confirmed the diagnosis of appendicitis. His teenage daughter underwent a successful appendectomy and recovered without incident. But to this father, the CAT scan was “unnecessary care” and done only to boost the revenue stream of the surgeon who ordered it or the hospital who employed him. God forbid, if the doctor was a partial owner of the scanner or imaging facility!!
You see, family doctors consider it standard of care to order a CAT scan and confirm the “clinical” diagnosis. They would have testified as such in a court of law against a surgeon if a CAT scan was not ordered. So even if the ER doctor and surgeon were 99% sure that the correct diagnosis was appendicitis, they would be outside the “standard of care” if they didn’t order a CAT scan.
They would face strict scrutiny if an appendectomy were performed and the diagnosis were found to be something else. And then the surgeon may have performed an “unnecessary” operation, done primarily as a source of income because “they get paid to do things.” So you can see where I am going with this.
It is why algorithms for treatment are not exact and won’t reduce cost of care or offer true quality. It is also why the relationship between provider and patient is so important. If there were a high level of trust, the physician could counsel the patient or family appropriately, and maybe avoid an additional test. And it is precisely why a third party payer distorts the relationship between the doctor and patient.
It is not as though doctors are constantly thinking that they may get sued or reported, but it does add layers upon layers to the interaction and complicate an encounter. Certainly this adds to the cost. Mostly, doctors want to do the right thing by their patient. All providers do.
And sometimes to try to help their patient and avoid accusations of improper care or missed diagnoses, they order tests which may be negative and of low yield. Thus is a fine balance that is the art of medicine.
So what do we do about it? Caps on awards or damages for pain and suffering? Exempt providers? I suggest that we adopt medical courts as a solution. Certificate of merits that determine if true negligence has occurred and if there is a correlation would be beneficial and reduce costs of defending a suit. Adopt the British system where the loser pays for the costs if a lawsuit is brought forward which proves to be frivolous.
A medical court system would have been very helpful in the Dupont litigation for silicone breast implants in which the science was ignored. The recent asbestosis and silicosis lawsuits would have taken a different flavor and those individual truly injured may have had a larger settlement.
Although President Obama acknowledged the impact, he offered no solutions. He instead provided a “confirmatory diagnosis” for a disease we already knew we had!
