Various Artists - How Do We Heal Medicine? lyrics

I got my start in writing and research as a surgical trainee, as someone who is a long ways away from becoming any kind of an expert at anything. So, the natural question you ask then, at that point, is "How do you get good at what you're trying to do?" And it became then, "How do we all get good at what we're trying to do?" It's hard enough to learn to get the sk**s, try to learn all the material you have to absorb at any task you're taking on; I had to think about how I sew and how I cut and also how I pick the right person to come to an operating room. And in the midst of all this came this new context for thinking about what it meant to be good. In the last few years we've realized we're in the deepest crisis of medicine's existence, due to something you don't normally think about when you're a doctor concerned with how you do good for people, which is the cost of healthcare. There's not a country in the world that now is not asking whether we can afford what doctors do. The political fight that we've developed has become one around whether it's the government that's the problem or is it insurance companies that are the problem. And the answer is yes and no, it's deeper than all of that. The cause of our troubles is actually the complexity that science has given us. In order to understand this, I'm going to take you back a couple of generations. I want to take you back to a time when Lewis Thomas was writing in his book, The Youngest Science. Lewis Thomas was a physician writer, one of my favorite writers, and he wrote this book to explain, among other things, what it was like to be a medical intern at the Boston City Hospital in the pre-penicillin year of 1937. It was a time when medicine was cheap and very ineffective. If you were in a hospital, he said, it was going to do you good only because it offered you some warmth, some food, shelter, and maybe the caring attention of a nurse. Doctors and medicine made no difference at all. That didn't seem to prevent the doctors from being frantically busy in their days, as he explained. What they were trying to do was figure out whether you might have one of the diagnoses for which they could do something. And there were a few. You might have a low-bar pneumonia for example and they could give you an anti-serum, an injection of rabid antibodies to the Bacterium Streptococcus, if the intern sub-typed it correctly. If you had an acute congestive heart failure, they could bleed a pint of blood from you by opening up an arm vein, giving you a crude leaf preparation of digitalis and then giving you oxygen by tent. If you had early signs of paralysis and you were really good at asking personal questions, you might figure out that this paralysis someone has is from syphilis, in which case you could give this nice concoction of mercury and arsenic, as long as you didn't overdose them and k** them. Beyond these sorts of things, a medical doctor didn't have a lot that they could do. This was when the core structure of medicine was created, what it meant to be good at what we did and how we wanted to build medicine to be. It was at a time when what was known you could know, you could hold it all in your head, and you could do it all. If you had a prescription pad, if you had a nurse, if you had a hospital that would give you a place to convalesce, maybe some basic tools, you really could do it all. You set the fracture, you drew the blood, you spun the blood and looked at it under the microscope, you plated the culture, you injected the anti-serum. This was a life as a craftsman. As a result, we built it around a culture and set of values that said what you were good at was being daring, at being courageous, at being independent and self-sufficient. Autonomy was our highest value. Go a couple generations forward to where we are, though, and it looks like a completely different world. We have now found treatments for nearly all of the tens of thousands of conditions that human being can have. We can't cure it all, we can't guarantee that everybody will live a long and healthy life, but we can make it possible for most. But what does it take? Well, we've now discovered 4,000 medical and surgical procedures, we've discovered 6,000 d** that I am now licensed to prescribe. And we are trying to deploy this capability town by town to every personal life in our own country, let alone around the world. And we've reached the point where we've realized, as doctors, we can't know it all. We can't do it all by ourselves. There was a study where they looked at how many clinicians it took to take care of you if you came into a hospital, as it changed over time. And in the year 1970, it took just over two full time equivalents of clinicians. That is to say it took basically the nursing time and then just a little bit of time for a doctor who more or less checked in on you once a day. By the end of the 20th century, it had become more than 15 clinicians for the same typical hospital patient. Specialists, physical therapists, the nurses. We're all specialists now, even the primary care physicians. Everyone just has a piece of the care, but holding on to that structure we built around the daring independence, self-sufficiency of each of those people has become a disaster. We have trained; hired; and rewarded people to be cowboys, but it's pit crews that we need, pit crews for patients. There's evidence all around us. 40% of our coronary artery disease patients in our communities receive incomplete of inappropriate care. 60% of our asthma stroke patients receive incomplete or inappropriate care. 2 million people come into hospitals and pick up an infection they didn't have, because someone failed to follow the basic practices of hygiene. Our experience as people who get sick, need help from other people, is that we have amazing clinicians that we can turn to. Hard-working, incredibly well-trained, very smart, with access to incredible technologies that give us great hope, but little sense that it consistently all comes together for you, from start to finish, in a successful way. There's another sign that we need pit crews, and that's the unmanageable cost of our care. Now, we in medicine, I think, are baffled by this question of cost. We want to say, this is just the way it is. This is just what medicine requires. When you go from a world where you treated arthritis with aspirin, that mostly didn't do the job, to one where if it gets bad enough we can do a hip replacement, a knee replacement, that gives you years, maybe decades without disability, a dramatic change, well, is it any surprise that that $40,000 hip replacement replacing the ten cent aspirin is more expensive? It's just the way it is. But I think we're ignoring certain facts that tell us something about what we can do. As we've looked at the data about the results that have come as the complexity has increased, we have found that the most expensive care is not necessarily the best care; and vice versa. The best care often turns out to be the least expensive. It has fewer complications, the people get more efficient at what they do, and what that means is, there is hope. Because if, to have the best results, you really needed the most expensive care in the country or in the world, well then we really would be talking about rationing. Who were going to cut off from Medicare, that would really be the only choice. But when we look at the positive deviants, the ones who are getting the best results at the lowest costs, we find the ones that look most like systems are the most successful. That is to say, they found ways to get all of the different pieces, all of the different components to come together into a whole. Having great components is not enough, and yet we've been obsessed in medicine with components. We want the best d**; the best technologies; the best specialists, but we don't think too much about how it all comes together. It's a terrible design strategy actually. If you, well there's a famous thought experiment that touches exactly on this. It says, what if you built a car from the very best car parts? Well, it would lead you to put in Porsche breaks, a Ferrari engine, a Volvo body, a BMW cha**is, and you put it altogether and what do you get? A very expensive pile of junk that does not go anywhere. And that is what medicine can feel like sometimes. It's not a system. Now a system, however, when things start to come to together, you realize it has certain sk**s for acting and looking that way. Sk** number one is the ability to recognize success and the ability to recognize failure. When you are a specialist, you can't see the end result very well. You have to become really interested in data, uns**y as that sounds. One of my colleagues is a surgeon in Cedar Rapids, Iowa, and he got interested in the question of how many CT scans did they do for their community in Cedar Rapids. He got interested in this because there had been government reports, newspaper reports, journal articles saying that there had been too many CT scans done, and he didn't see it in his own patients. And so he asked the question: how many did we do, and he wanted to get the data. It took him three months, no one had asked this question in his community before. And what he found was that, for the 300,000 people in their community, in the previous year they had done 52,000 CT scans. They had found a problem. Which brings us to sk** #2 a system has. Sk** #1, find where your failures are, sk** #2 is, devise solutions. I get interested in this because the World Health Organization came to my team asking if we could help with the project to reduce d**hs in surgery. The volume of surgery had spread around the world, but the safety of surgery had not. Now our usual tactics for tackling problems like these are to do more training, give people more specialization, or bring in more technology. Well in surgery you couldn't have people who are more specialized and you couldn't have people who are better trained and yet we see unconscionable levels of d**h, disability that could be avoided. And so we looked at what other high-risk industries do; we looked at skyscraper construction, we looked at the aviation world. And we found that they have technology, they have training, and then they have one other thing: they have checklists. I did not expect to be spending a significant part of my time as a Harvard surgeon worrying about checklists. And yet what we found was that these were tools to help make experts better. We got the lead safety engineer for Boeing to help us. Could we design a checklist for surgery? Not for the lowest people on the totem pole, but for the folks who were all the way around the chain, the entire team, including the surgeons. And what they taught us was that designing a checklist to help people handle complexity, actually involves more difficulty than I had understood. You have to think about things like pause points, you need to identify the moments in a process when you can actually catch a problem before it's a danger and do something about it. You have to identify that this is a "before takeoff" checklist. And then you need to focus on the k**er items, in aviation checklists like this one for a single engine plane. It isn't a recipe for how to fly a plane; it's a reminder of the key things that get forgotten or missed if they're not checked. So we did this. We created in 19 item, 2 minute checklist for surgical teams. We have pause points immediately before anesthesia was given, immediately before the knife hits the skin, immediately before the patient leaves the room. And we had a mix of dumb stuff on there making sure an antibiotic is given in the right time frame because that cuts the infection rate by half. And then interesting stuff for something as complicated surgery, instead you can make a recipe for how to have a team that's prepared for the unexpected. And we had items like making sure everyone in the room had introduced themselves by name at the start of the day, because you have to dozen people or more who are sometimes coming together as a team for the very first time that day. We implemented this checklist in eight hospitals around the world, deliberately in places from rural Tanzania to the University of Washington in Seattle. We found that after they adopted it, the complication rates fell 35%, fell in every hospital it went into. The d**h rates fell 47%. This was bigger than a drug. And that brings us to sk** #3: the ability to implement this. To get colleagues across the entire chain to actually do these things. And it's been slow to spread; this is not yet our norm in surgery. Let alone making checklists to go on to childbirths and other areas. There's a deep resistance because using these tools forces us to confront that we're not a system, forces us to behave with a different set of values. Just using a checklist requires you to embrace different values from ones we had like humility, discipline, teamwork. This is the opposite of what we were built on: independence, self-sufficiency, autonomy. I met an actual cowboy, by the way. I asked him what was it like to actually herd a thousand cattle across hundreds of miles. You know, "How did you do that?" And he said, "We have the Cowboys stationed at distinct places all around, they communicate electronically constantly, and they have protocols and checklists for how they handle everything from bad weather to emergencies, to inoculations for the cattle." Even the cowboys are pit crews now, and it seems like time that we become that way ourselves. Making systems work is the great task of my generation of physicians and scientists. But I would go further and say that making systems work, whether in healthcare; education; climate change; making a pathway out of poverty, is the great task of our generation as a whole. In every field, knowledge has exploded, but it has brought complexity, it has brought specialization. And we come to place where we have no choice but to recognize as individualistic as we want to be, complexity requires group success. We all need to be pit crews now. Thank you.
