Pat Summit

Starting in the Fall, while surfing those TV channels, one would sooner or later chance on a basketball game…personally, when I chanced on a Lady Vols game, I would stay on that channel for just a little longer….just so I could watch her. She exuded a kind of strength – the tough, steely, bend-but-not-break type…it drew you in….sort of made you sit up straight and behave…..now she is gone!…..Pat, it sure was what it was but in the end, it was what you made it – an amazing life. Fare thee well!

The Angry Men

Once upon a time, the earth was flat. People stayed where they were, afraid to go too far least they fall over the edge into an abyss.
Then science and technology changed all that. People realized that the earth was round and dared to believe that they could get to other side, one way or the other. A wave of exploration and globalization was ushered in. New lands and markets were found. That brought with it wealth for some but pain and suffering for many. It ushered in a wave of terrorism.
Yes, terrorism!
Whole races were decimated and destroyed, people traded like cattle across seas. Curiously, all that pain and suffering was somehow justified by the religious beliefs of the day.
With time, the conquering race settled back to enjoy it’s spoils, content to leave the decimation it had wrought behind. After all, those other people were on the other side of the world, far, far away.

Then an interesting thing happened. Technology struck again and ushered in another wave of globalization. This time, it flattened the earth – virtually – creating a global village. Even as goods and services streamed one way, the forgotten people on the other side started streaming the other way. For some weird reason, terrorism always seems to follow globalization and this time around, it is no different. And it is again finding justification in religion.
Now there are angry men overall, standing up to defend what they have, who they are and their way of life. I wonder if there were such angry men hundreds of years ago among the people who were killed or traded. I guess their angry voices were drowned out by the din of gunfire and the screams women and children.
This time though, at least for now, the din of gunfire and the screams of women and children are far away, so the voices of the angry men are really loud and clear and can be heard all over the global village.

Hundreds of years ago, globalization changed the lives and cultures on many. Maybe the angry men are astute students of history and see this happening to their cultures and are fighting to preserve what they have.
Who will prevail? The forces of technology and globalization or the angry men?
I wish I knew…I wish I knew….

It can be chronic

One day if I get the platform, this is an address I’ll love to give to the Ghanaian public. The topic will be on the issue of Chronic Diseases.
It’ll probably be in the evening and I’ll probably start like this…

Good evening, ladies and gentleman. Thanks for tuning in. Tonight, I want to talk to you about the issue of Chronic Diseases.
Everyone knows what a disease is and what it entails. It makes you sick and forces you to seek treatment. Some of you go to see a doctor. Others opt to see a traditional healer or herbalist. A few may do the unthinkable and just hope the disease goes away by itself. Whatever the measure taken, the hope is that the doctor, traditional healer, herbalist or time heals the body of the disease and brings back normalcy and good health. That is the general expectation.
However, what if the disease is such that no matter what the doctor or herbalist does, it does not go away or keeps coming back? There is a chance that the condition is not being treated well. However, there is also the possibility the disease is chronic.
Chronic diseases are long-term medical conditions that are generally progressive or persistent. They last longer than three months. Examples of chronic diseases are high blood pressure, diabetes, end-stage kidney disease, asthma, hepatitis C and cancer.

It used to be thought that the most important health issue in sub-Saharan Africa (SSA) was that of the infectious disease e.g. malaria, tuberculosis, cholera. Infectious diseases are still a major health risk in SSA but I contend that a few chronic conditions also are exacting a heavy toll on the populations in the region. I further seek to explain why the mentality of the population might affect how these chronic diseases are managed.

Of the examples on chronic diseases stated above, the two most common in Ghana seem to be high blood pressure (HTN) and diabetes.
In 2004, a study of the Greater Accra area found an urban prevalence of HTN to be 32.9% and a rural prevalence of HTN to be 24.1%. Similar studies in the Ashanti Region yielded prevalences of 33.4% and 27% respectively. A review of about seven studies by Addo has the rural prevalence at about 19% and the urban at about 55%
Diabetes on the other hand has a prevalence of about 6 – 9%, that is over 2 million people.
The mean age of diagnosis for both diabetes and high blood pressure seems to be in the mid-thirties.

Now both high blood pressure and diabetes can lead to very serious healthcare problems down the line if not managed well.
High blood pressure can lead to stroke, congestive heart failure and to loss of kidney function and even death.
Diabetes can lead to loss of limbs, blindness, loss of kidney function and death.

So it is of utmost importance for these diseases to be managed well. That is where the problem of the mentality comes in.
If a disease is always seen as a condition that can be treated away (acute), then getting patients to accept the fact that a disease can be chronic presents a problem.
Patients may not believe the diagnosis and seek a second opinion from another physician or traditional healer of even worse, do nothing about it. The fact that some diseases cannot be cured can be a bitter pill to swallow.

Then is what I call the “The Falsehood of Eternal Youth and Health”. Excuses like “I’m too young to have high blood pressure or too active to have heart disease” are common. Well, youth passes, even if slowly and good health is not always assured. Besides black people seem to have a propensity for certain ailments, one of them being high blood pressure.

The other issue is that chronic diseases demand a much higher level of patient involvement in managing the disease. Insulin must be injected, tablets taken daily for that high blood pressure, diets, exercise….it gets overwhelming and the onus is totally on the patient. Further, managing chronic diseases can be a financial as well as time drain. Consider having to undergo hemodialysis three times a week or the cost of medications to manage high blood pressure.
It is not at all surprising that faced with these prospects, some patients seek another way out – a cure from, say, a traditional healer or herbalist or just denial. In our Ghanaian culture, the rush to attribute a chronic ailment to a supernatural cause is ever present. That unfortunately leads down a path of figuring out the supernatural cause instead of treating the disease.

The Swiss psychiatrist, Elisabeth Kübler-Ross describes in her 1989 book, On Death and Dying, five stages that patients go through when faced with the diagnosis of severe illness. They are Denial, Anger, Bargaining, Depression and Acceptance. One is supposed to move from one stage to the next and finally end up accepting the diagnosis. It is in the acceptance of the diagnosis that propels a patient to deal and live with it. If one never gets to the acceptance stage, the results are the early end-stage effects of a disease.

This can be devastating if the patient is young, say, in their thirties.
If diseases like diabetes and high blood pressure, diagnosed when one is thirty are mismanaged or neglected, then by the time one is in his forties, the end effects of these diseases are apparent and lead to early morbidity and mortality.
These diseases need to be taken seriously and managed well, the minute a diagnosis is made, irrespective of the age.

The great thing is that, with all the advances in modern medicine, chronic diseases can be so managed as to ensure a long life. It however takes an active, very active participation of the patient.
Diabetes and high blood pressure are not the only chronic diseases. Like I mentioned earlier, I used them since they are the most common. There are of course people dealing with diseases like HIV, Parkinson’s, cancer, arthritis, asthma, kidney failure and congestive heart disease. Whatever the disease is, the same principle applies – acceptance.

So to summarize, not all diseases are acute e.g. malaria, and can be treated away. There are the class of diseases that persist and are chronic. Recognizing them for their severity and accepting them as manageable conditions si the first step and avoiding the late term effects of these diseases.

Thank you for listening and take good care of yourselves. You deserve that. Have a good night.

Once Upon a Time

“Somewhere, something incredible is waiting to be known.” – Dr. Carl Sagan

In August of 1810, the English writer, Frances Burney, then living in Paris with her husband, General Alexandre D’Arblay and son, Alexander, developed pain in her right breast. She saw several French doctors. Fearing she may have breast cancer, a right mastectomy was ultimately recommended. The surgery was scheduled for September 30, 1811. In a period where surgery was done without anesthesia, she was given only a 2 hour notice. This was so she wouldn’t be frightened off. The surgery was attended by “7 men in black, Dr. Larrey, M. Dubois, Dr. Moreau, Dr. Aumont, Dr. Ribe, & a pupil of Dr. Larrey, & another of M. Dubois”. She was given some wine cordial after which she lay on the mattress designated as the operating surface. Her face was then covered with a transparent handkerchief. Below is part of her account of what happened:

“When the dreadful steel was plunged into the breast—cutting through veins—arteries—flesh—nerves—I needed no injunctions not to restrain my cries. I began a scream that lasted unintermittingly during the whole time of the incision—& I almost marvel that it rings not in my Ears still! So excruciating was the agony!”

Frances Burney survived the the mastectomy and lived another 29 years, dying at the age of 87. After the operation, she couldn’t think or speak of it for several months, had terrible headaches but had the courage to write an account of it to her sister.

Surgery before the discovery of anesthesia was so barbaric, some surgeons got drunk together with the patient for the ordeal. Surgeons were known to enter the theater with a bottle of wine in each hand – one for the patient and one for the surgeon. John Hunter, an early Scottish surgeon described surgery as ‘a humiliating spectacle of the futility of science’ and the surgeon as ‘a savage armed with a knife’! Techniques that were used to make it bearable for the patients included alcohol, opium, knocking the patient out with a blow to his jaw, rubbing them with stinging nettles and hypnosis. Patients would vomit and aspirate, blood loss was massive and the screams were haunting.
Now surgery is a painless, safe affair thanks to all the advances in anesthesiology, surgery and pharmacology.

Medicine and surgery have come really far from the days of Hippocrates. Matter of fact, they have even come father since a hundred years ago! Beliefs have changed and practices improved due to research. Whole diseases like the small pox have been eradicated even if we have replacements like HIV.

Talking about beliefs, the ancient Greeks, based on the teachings of Plato and Hippocrates, believed a woman’s womb was a separate creature with a mind of it’s own. When a woman did not bear children or abstained from sex, her uterus, hungry for children, could dislodge and float freely about her body causing shortness of air, seizures and mania. Women were advised to marry young and have a ton of kids. For a womb that had already broken free, doctors would “fumigate” the patient’s head with sulfur and pitch while simultaneously rubbing scented oils between her thighs. Why? The womb would flee from the bad smells and move back into its rightful place!

Or take the practice of bloodletting. The practice was common in ancient Egypt and got carried over to the Greeks, with Hippocrates and Galen being huge proponents. It was believed then that the human body contained the four “humors” – blood, phlegm, black bile, yellow bile – each centered in a particular organ—brain, lung, spleen, and gall bladder – respectively. Disease was thought to be from over-abundance of the humor blood so “letting” blood out of the body, brought the humors back in balance and healed the sick. Menstruation was seen as the body’s natural way of bloodletting to balance out the humors.
Now there are conditions like polycythemia vera, where the body produces too many red blood cells. A treatment option is bloodletting (Phlebotomy) and that is done even today. However bloodletting then was done for any and all ailments!
Bloodletting was common practice till the 18th century in Europe and the 19th in the US. As late as 1942, there were medical textbooks with bloodletting as a therapeutic procedure for all sorts of conditions. Dr Benjamin Rush, one of the signatories of the Declaration of Independence, was a fierce proponent of the practice.
The most famous victim of bloodletting in the US is probably the first president, Gen. George Washington. He had been sick and unable to swallow from a severe throat infection for a few days. On December 14, 1799, he asked his physicians to perform bloodletting on him. 124 – 126 ounces (3.75L) of blood was let out over a ten hour period by his physicians. The president weighed about 230 lb (104.5 kg) and was 75 in tall. Since the blood volume in an adult male is 70 ml/kg, his total blood volume was about 7.3 L. This means that, on the day he died, his physicians let out half of his blood volume. We know today that, that amount of blood loss leads to profound hypotension, shock, organ hypoperfusion and death. No wonder the president appeared calm before his death. He was probably in shock!
Luckily, there were men like Pierre Louis (1787-1872) and John Hughes Bennett (1812–1875) whose statistical analysis of medical data then helped put an end to the practice.

It’s not only beliefs and practices that have changed over time but also some drugs used. To mind comes mercury. A heavy metal, it is now known as a very toxic substance. It comes in three forms – elemental mercury, inorganic salts, and organic compounds. The organometallic Methylmercury is the most poisonous. Nowadays, mercury is found mostly in whale and dolphin meat, certain fungicides and skin lightening products.
It causes irreversible damage in fetuses, infants, and young children. It is damaging to the the neurons and causes cerebral infarctions, causing Minimata disease (Ataxia, Visual-field loss, Psychiatric disturbances, Sensory loss and Chronic Paresthesias). It is also toxic to the kidneys. The phrase “mad as a hatter” comes from the times when mercury compounds were used for the production of felt hats and led to the poisoning of the workers in the 18th – 19th centuries. So we can agree that mercury is bad.
Well, the Persians, Greeks and Chinese thought it increased vitality. The Chinese Emperor Qin Shi Huang died after ingesting mercury pills designed to make him immortal! From the 17th to 18th century, a drug called “Blue Mass”, containing 33% mercury was used to treat syphilis tuberculosis, constipation, toothache, parasitic infestations, and the pains of childbirth. From about 1930 till 1999, Thimerosal, a mercury-containing preservative was used in some vaccines. Thankfully, there is great awareness of the dangers of mercury now.

It is definitely a great time to be practicing medicine. Even as we hurtle along, ever adding newer drugs, treatment options and procedures to our armamentarium, lets not forget where we as healers have come from.

Let’s Remember

“What difference does it make to the dead, the orphans and the homeless, whether the mad destruction is wrought under the name of totalitarianism or in the holy name of liberty or democracy?”
― Mahatma Gandhi

Alexander the Great led his men to war, Genghis Khan did the same… the great Shaka Zulu, was front and center….Hitler sent men to die from the comfort on his bunker in Berlin…the Emperor of Japan from the comfort of his palace.
The great warriors who led their men knew the gravity of war and got good counsel before they did…Aexander the Great from Aristotle
In the world we live in now, the leaders do not have to lead their men to war. Even the advisors have never seen a battlefield. It’s easy to yell, “Attack” from the comfort of an air-conditioned office!

Once upon a time these were not just headstones – they were sons, daughters, dreams, hopes, laughter, love, joy…they gave it all away on behalf of others so let’s remember!

Maame Maya!

I would have called you Maame Maya…it’s been 2 years today since you left us….back in the 60’s, you came down and lived in Accra, you learnt Fanti, you loved kenkey, worked at the Ghanaian Times, mastered our sayings like “Be careful when a naked person offers you a shirt”…you wrote about the “ceremonial fontonfrom drums waking the morning air in Takoradi”…your poems grace my bedside table for still, I need to rise….you may be American by birth but your soul was and will always be ours….Dr Maya Angelou, RIP!

Take Subjectivity Out

“Nothing that has value, real value, has no cost. Not freedom, not food, not shelter, not healthcare” – Dean Kamen

A young woman presented for a thoracotomy to remove a mass in her right chest. On my way to see her, her nurse accosted me and told me of the patient’s demands. She didn’t want to wake up in pain – fair enough – but she didn’t want an epidural either! It went on – no ribs were to be broken, she didn’t want a foley catheter and she wanted to be discharged the next day. I actually laughed out loud when the nurse told me this.
I walked up to the patient with a smile on my face that got wiped off by the chilly reception. I tried to explain to her that her demands were unrealistic. She wouldn’t hear of it. I called in the surgeon for reinforcement. We lost the battle. She walked out.
Now imagine there was a tool online that allowed patients to rank the quality of care they received at a hospital based on several questions about interacting with the doctors and nurses, like “Were they responsive to your needs?”
How do you imagine this young woman’s ranking will look like?
Oh yeah, there are already such online tools and it is interesting to read through them.
Which brings me to today’s question – “Using the responses from patients about their care in an inpatient setting, can one really extrapolate the quality of care received?”
My answer to that is big NO!
In medicine (and probably other professional fields too), there is always this big disconnect between physicians who actually take care of patients and those experts who hardly take care of patients so have time to make policy.
Irrespective of what so-called policy makers in some big institutions might preach, using patient satisfaction surveys as a window into the quality of care received in the inpatient setting is going down a very slippery slope of subjectivity.
Even surveys about patient satisfaction in the outpatient setting have been shown not to capture the real issue at hand but rather how long patients waited!
Healthcare is a huge sector. Certain sections can be evaluated using consumer feedback e.g nursing care, drug development, emergency care, public health, the control of chronic diseases. However, when it comes to inpatient care, do you honestly think you can get a patient to objectively tell you through a questionnaire how well a surgeon took out a tumor or replaced a heart valve or a knee or treated pneumonia or a heart attack?
How many of us know the surgeon with the hands of Asclepius but the demeanor of Sergeant Hartmann from the 1987 movie “Full Metal Jacket”?
What is mostly obtained from these patient surveys is the quality of nursing care and the human-to-human interactions. They also capture complications and I’ll come to that later. The reviews however miss the meat – the quality of medical care or surgical interventions.
Now, is it necessary for the public to have an idea of the quality of care they’ll get from a hospital? YES! Healthcare is a service industry and I think it is important for patients to have such a tool.
Let’s say you need to have a hip replaced. Imagine you could go into a tool that showed you each orthopedic surgeon in town, how many hips they did a year, which age group, which ASA class, length of a procedure, number and nature of complications, incidence of transfusions, length of stay and cost. Wouldn’t that be a much better tool than patient surveys?
Now how would such a tool be set up and populated? Setting it up would be the least of any developer’s worries. Populating it is the problem. The only way to get that information is to make hospitals report outcomes for each physician who works at that hospital. That way, consumers can compare. No hospital in the US is going to do that! They collect it but they aren’t sharing it!
And so policy makers grasp at straw by designing surveys based on patient experiences that seek to eke out the quality of care.
However, I think hospitals should publicize this data. It will allow competition in the marketplace, weed out the bad practitioners and lower costs. It will allow patients to choose the best surgeon for their needs. An ASA Class III or IV patient can look for a surgeon who does mostly ASA Class III and IV patients.
It also prevents doctors and hospitals from having to deal with policies that make practicing more difficult but do not really improve quality of care. I think we in healthcare should be more proactive in measures that bring patient care to a pact between a doctor and a patient, excluding insurance companies and government.
So next time you fill out a patient satisfaction survey, ask if it really captured the quality of care? It probably did not but these surveys can capture outcome in terms of complications. The question then is, “Are complications an indicator of quality of care?” To that I’ll respond with yes and no. Complications can be a window into quality of care or also very much patient related. Going back to hip surgery, if a surgeon does 350 hips in a year and out of that 50% have infections, there is a problem. However if a patient after valve replacement surgery with a mechanical valve goes home, forgets to take his warfarin and the valve clots off, that is on the patient.
As a consumer of healthcare, I’ll like to know what I’m getting when I walk in for a procedure. I wish there was a better way to tell than through subjective responses.

Conversations

And then He took me to the top of the mountain and said, “Visualize a World with no strife!”…So I closed my eyes…and that is when I saw the chasm – a great chasm it was indeed…on one side was much prosperity and abundance and on the other much need, hunger and suffering…I opened my eyes and asked Him, “I see a great chasm. How can I visualize no strife with such a great chasm?”…He looked at me, smiled and said, “Fill the chasm!”…So I asked, With what?”….He said, “With Empathy”.

Then we entered the banquet hall – a huge cavernous place. It was the strangest place ever. At one end sat guests who were gouging themselves on large plates of food. Their full bellies glistened in the harsh light as crumbs and drops fell from their full mouths to the ground.
At another section were several guests sharing a plate of food. Their faces were glum for you could tell they did not have enough…..
And then was the last section where the guests looked like they were not even at the banquet. They were doubled over, faces contorted in apparent pangs of hunger. A few were even motionless on the floor.
I stopped, surprise etched on my face…. I asked Him, “Isn’t there enough food for all the guests?”….He looked me like you looked at a clueless son and replied, “You’d think, right?”

Happy Birthday, Malcolm!

“I don’t feel that I am a visitor in Ghana or in any part of Africa. I feel that I am at home. I’ve been away for four hundred years, but not of my own volition, not of my own will. Our people didn’t go to America on the Queen Mary, we didn’t go by Pan American, and we didn’t go to America on the Mayflower. We went in slave ships, we went in chains. We weren’t immigrants to America, we were cargo for purposes of a system that was bent upon making a profit…..When I was in Ibadan at the University of Ibadan last Friday night, the students there gave me a new name….. “Omowale,” which they say means in Yoruba…. ‘The child has returned'”.

Happy Birthday, Malcolm! You would be 91 today! Admire you for how you turned your life around!

Protocolize It!

We live in the era of big data. With the introduction of electronic medical records, big data is also alive and well in medicine. Mining that data can help establish therapies that are most effective in the majority of patients. The mined data plus results from large scale prospective, randomized studies then result in recommendations and protocols that are supposed to improve patient outcomes.
A majority of physicians have historically looked at medicine as an art. Each physician had his or her way of treating ailments, often tailoring them to fit individual patients.
Medicine however is moving in a direction where the “Medicine as an Art” crowd is on the edge of extinction.
Who is right? Should the practice of medicine be based on protocols or should it be practiced as an art?

I’ll start off the discussion with two examples:
Close to a million Americans suffer from strokes each year and it’s the number 4 killer in the US.
For years, different hospitals and physicians have managed patients with strokes differently. Studies show that if patients having ischemic strokes are given intravenous tissue plasminogen activator (tPA) to bust the clot causing the stroke within 60 min of arriving at a hospital, their chances of survival go up significantly. However, a study in 2014 showed that less than 30% of ischemic stroke patients were being treated this way. On the other hand, hospitals that had established protocols to facilitate this recommendation lowered the incidence of death and disability from stroke.
Another area of concern is that of medical errors. The “To Err is Human” report sounded the alarm bell in 1999. That in part led to the institution of the Surgical Safety Checklist and the “Time Out” for all surgical procedures. A 2009 study in the NEJM showed a drop in death from errors from 1.5% to 0.8% since institution of the checklist and “Time Out”. Inpatient complications dropped form 11% to 7%.

These two examples illustrate the fact that protocols based on science and solid evidence can positively affect outcomes.
Should this then be extrapolated to all of medicine? Should every decision we make be decided by protocols culled from studies and hard data?

Which brings me to the other side of the coin.
Say a study S looks at therapy for say, Prostate Cancer, in a 1000 men. if this therapy is effective in 86% of the men and it gets adopted, what happens to the 14% who do not benefit from the therapy.? if one extrapolates that to a million subjects, that 140,000 men who do not benefit from this new therapy. A good protocol has to allow a physician to cater to this group.
Recent recommendations about two tests that affect men and women have raised the ire of patients. The first is mammography to screen for breast cancer in women and the Prostate Specific Antigen (PSA)to screen for prostate cancer in men. In both cases, based on data, the opinion was that they led to an increase in the false positive diagnosis of a cancer. In other words, patients were thought to have cancer who did not. This led to further unnecessary testing and procedures. With the PSA, it is thought that a lot of small prostate cancers could be diagnosed, which left alone would not grow to be a problem. Now imagine telling a patient:
“You have cancer but it is so small we are going to leave it alone. You will outlive it.”
Sure, in a calm and reassuring manner, a doctor can try to make a patient understand but how many will bear to live with that uncertainty. Then there is also the probability that that small cluster of cells could get bigger….So why not get them out now?
Even if these cancers are small, isn’t it the smart thing to do to diagnose them and follow them? Doesn’t that make these screening tests then necessary? Doesn’t that give the patient a choice?

The point I am trying to make is, in spite of all the data, there are these people called Patients who we are supposed to serve. They are ruled by emotion and are not always as rational as the data and evidence. Is it part of “doctoring” to do whatever is possible, besides causing harm, to reassure these patients?
So on one side are the those who preach a strict adherence to the evidence and on the other those who want to tailor things to the needs of the patient and the habits of the physician.

Into this fray drops Genomic Medicine. This is an emerging discipline that bases therapy on a patient’s genome. It is a well known fact that some drugs (e.g. Plavix) do not work in some patients because of lack of or too much of certain enzymes. Before a particular therapy is initiated, the genetic make-up of a patient is determined. It is now used extensively in psychiatry to get effective therapy.
This shows that in spite of the data or evidence, there are still individual variations.

All these arguments may not matter because of the Affordable Care Act.
The Affordable Care Act has decimated the private medical practice to the point where the majority of physicians are now employed by hospitals. The Act also rewards physicians whose practices are in line with the latest most effective therapy and management modalities. Hospital administrators are then going to compel their physicians to practice in accordance with protocol that fit the best recommendations. In that sense, the autonomy of the physician may already be a thing of the past and patients’ choice may be slowly narrowed to a few options.

All this makes me wonder what role the physician may play in medicine in the future. If every decision we make is based on a protocol, what will happen to the practice of medicine as we know it? Besides surgeons, are any other specialties even needed if all one needs is to follow a protocol? Protocols so simple that even a caveman can follow them? What are we then good for?
