Ignaz Semmelweis
People keep pressing for mandatory reporting. They press for
laws that will force health care professionals to report what patients need to
know to survive. When they don't press for that, they press for restoring empathy
and compassion. People who press for these things are people who don't know
history. It is a conversation we have been having for at least 160 years.
Most people have heard of MRSA by now. It stands for
Methicillin-resistant Staphylococcus aureus, a bacterial infection that, by
using so many antibiotics, we have bred to be resistant to antibiotics.
Overusing antibiotics robs future generations of the ability to benefit from
them - just one of the reasons why it is important for the patient community not
to be infected in the first place, especially by caregivers.
Ignaz Semmelweis is the man who first figured out that
something could be done to prevent patients from being infected by their
caregivers. He is so renowned for the discovery that asking someone in medicine
who Semmelweis is would be like asking someone born and raised in the United
States who George Washington is - with the difference that they don't know two
of the most important lessons to be learned from him.
Semmelweis practiced medicine during the mid 1800s. When he
first graduated from medical school he was unable to get a position as an
internist, so he became an obstetrician. He was put in charge of two government-supported maternity wards. Among his duties were examining every patient
everyday in preparation for the professor making his rounds, and he was in
charge of all the records.
The fact that then, as now, almost no adverse events get
reported accurately (see
Medical Reporting) was a problem he could
overcome because he saw every patient everyday
himself and he saw all the records made by others. What was going on in the institutions
was hard to hide from him.
Here is one of the things he saw. The first
maternity clinic had a mortality rate that varied from month to month from 10%
to 30%. The second had a mortality rate closer to 4%.
Young pregnant women are very interested in learning how to
survive the new world they are about to enter. Among other things, they pay
attention to other pregnant women. When they see 1 in 3 of their friends die in
one clinic one month, but not in the other, they care. The public knew the first
maternity clinic was a death trap. The caregivers knew it too, but they still
sent patients there. This is one of the most important things that patients
should understand. Then, as now, caregivers send patients into death traps.
After all, most patients didn't die.
The chief difference between then and now is that back they
at least they knew which clinic was a death trap. Today, they don't know.
Adverse events are erased in medicine whenever possible. Today no one has an
accurate grasp of where safety is.
Semmelweis knew. And all of his patients were young pregnant
women. There are few things on earth more compelling than a young pregnant
woman. Semmelweis
wrote about facing women who, when told they were being sent to the first
clinic, got on their knees pleading not to be sent there. One of the unfortunate aspects of being a patient is having to find ways to motivate caregivers to
care. Enough young pregnant women pleading with him finally got Semmelweis to care.
And that is why he is
so important in the history of medicine.
He began analyzing what was known. He searched for
differences between the two clinics, even baring some religious practices to see
if that made any difference. He could find nothing wrong.
Then a friend of his who worked in the first clinic was
helping students with an autopsy when the scalpel of one of the students slipped
and cut his friend. The fever killing so many young mothers in the delivery room
was the same fever his friend died of in the autopsy room This was before bacteria had been discovered. So Semmelweis speculated
that perhaps some cadaverous material, as he called it, was traveling on the
hands of the students from the autopsy rooms to the delivery rooms.
The first clinic was a teaching clinic. The workers were students.
In the second clinic the workers were midwives. Throughout history, until
recently, the chief tool for teaching medicine was cadavers. The students would
be doing an autopsy in one room when suddenly a woman went into labor and they
would rush to deliver her baby. Then they would return to doing the autopsy.
Semmelweis tried an experiment. He ordered the students to wash
their hands before going from
doing autopsies to delivering babies. In three months the death rate
dropped to zero.
Semmelweis reported this amazing discovery, that washing
hands saves lives, but did other physicians start doing that? No. And for the
160 years since we have continued to have the same conversation about how to get
caregivers to give care in the ways that would avoid infecting patients and
avoid the many other problems resulting from caregivers not behaving the way
patients need them to behave.
Today
we know how to reduce infection rates in hospitals to zero, but they
don't do it. They cannot be persuaded to do it. They say it would take
too much time.
Semmelweis was able to get the students in the dangerous
clinic to do it because they were students. They had to do what he said. Doctors
don't have to do what anybody says. And the well being of doctors is improved by
letting patients get infected because other patients cannot not find out about it and
avoid physicians and facilities who kill patients habitually. The number of patients who come to them is not effected by
whether or not they take the time to keep patients safe. So there is no
advantage in it for providers to prevent those infections. In fact, there is an
advantage in letting patients get infected. It saves providers time and it
generates additional treatments for which they can charge when patients become
infected. They make more money by infecting patients.
So Super Bugs Evolve
One new bacterium now resistant to many
antibiotics is Clostridium difficile, a germ that causes deadly intestinal
infections in hospital patients. It recently has been discovered that it can
spread through the air. It sends out a spore that lands on surfaces where it is picked up by hands.
Those hands spread it.
Normally other bacteria that live in our intestines keep it
from being a problem, but the broad spectrum antibiotics given to hospital
patients wipe out those beneficial bacteria already in the intestines of
patients and allow Clostridium difficile to flourish
and broadcast more spores into the air. The spores are resistant to
disinfectants and can survive in open areas for months.
Anyone with diarrhea could be spreading it. Catching it can
produce fever, nausea, abdominal pain, severe diarrhea and sometimes colitis.
The best way to prevent its spread? Washing hands. Because hospital personnel do
not disinfect their hands enough, antibiotics have had to be used so many times to
save patients from it that it has become resistant to those antibiotics.
If the patient community could learn where the biggest
problems with this infection were, they could avoid those places. If patients
avoided those places, providers would find the time to clean up the problem
because their own well being would depend on it.
Passing another rule requiring better behavior has not
increased hand washing enough in 160 years. Appointing another watchdog or
implementing another best practices policy has not either. Patients really need
to be able to see the facts of what and where such problems are in order to make intelligent cost-benefit analyses.
An informed patient community can make its well
being important enough to the well being of care givers to cause them to clean
up their acts.
Care givers don't care where the death traps are as much as
they care about protecting their own well being. If they did, they would know.
And they don't. The only reason Semmelweis cared is that his patients knew
because they were in a unique situation that enabled them to figure it out for
themselves. That's the position patients need to be in again today. Otherwise it
will continue to be in the interest of medicine to infect patients.
According to the Centers for Disease Control, of the patients
that our caregivers infect, 99,000 die each year. That means a number many times
larger than that are disabled, but do not die from it. And not one of those
deaths is the result of an error. The means to prevent each of those infections
is known and available, but it is calculated that it would take too much time.
That is why the symbol for patient safety should be a
chalk outline.
If the symbol is not a chalk outline, it should be a graphic
representation of concerned people having the same conversation for 160 years
without figuring out that it is the wrong conversation.
