Using Your Strengths

First, I apologize for not posting more regularly recently. I had a week of travel come up that I hadn’t expected and it threw a small wrench in some work plans. I’m not complaining though, I’d much rather be busy than idle.

A friend of mine connected me to a video titled Look at Yourself after Watching This that I think is a must-see. It’s just over four minutes and worth your time. It got me thinking about how much in life we take for granted.

Some experiences about a year ago really brought me down emotionally. Instead of looking at the opportunities that resulted, I focused on the problems. I didn’t look for solutions, I got stuck just thinking about how complicated the whole future looked.

Watch the video and think about how even in the midst of adversity you can turn a lousy hand into a winning one. Think of the number of lives that Nick Vujicic has touched by turning some incredible difficulties into a blessing for those around him. All you have to do is watch some of the expressions in the video.

That led me to thinking about how we often focus on the things in which we struggle instead of those in which we excel. Why is that? Shouldn’t we be taking our natural talents and abilities and making the most of them instead of trying to fix things in which we aren’t gifted? That’s kind of the point of Strength’s Finder 2.0. Tom Rath examines this phenomenon and makes a clear argument on why we should be spending much more time focusing on where we excel. Each copy of the book has a unique code to allow you to take an online assessment test (you will need to purchase a NEW copy of the book to get your code) that will help you find your top five strengths.

A couple of friends of mine read the output from this assessment. What was really surprising was that independently of each other and without knowledge of what the other said, they both indicated that reading it was like reading my biography. I was a bit stunned. This is incredibly powerful material.

Take a chance and find out what your unique gifts are to the world. Turn things that you may have thought of as challenges into something that makes you a power and force to be reckoned with. Become an agent for change in the world around you.

Please let me know if you’ve tackled this. It’s really a very small investment of time that will help you understand yourself better, help you show others what you can do, and make you more effective in the world. I’d love to know about your results either by posting comments here or by letting me know privately.

The Risks of Confounding

A study was just published titled “Short term effects of temperature on risk of myocardial infarction in England and Wales: time series regression analysis of the Myocardial Ischaemia National Audit Project (MINAP) registry” in the British Medical Journal. It’s kind of a mouthful but the authors are trying to draw a link between the risk of a heart attack with decreasing temperature.

There are probably a couple of factors in this that make this study somewhat flawed. The use of ambient temperature as an indicator for a heart attack in this case could be technically called a confounding variable. Here is a classic example to explain exactly what that is.

Assume a researcher wanted to study the causes of lung cancer but had no idea what factors could contribute to the development of disease. A case-control study would be the typical design used to look for the variables that contribute to disease. In essence, it takes a group of people and assigns them to two different groups – those who have disease and those who do not. The researcher would then look at variables that might explain the cause of the disease in the group that is ill.

Let’s say that our hypothetical researcher decides to study the presence of a lighter in a pocket or purse thinking that maybe some of the chemicals in the butane might cause lung cancer. Statistically, this variable is going to show up as a significant factor contributing to lung cancer. This is where we run into the problem of causality versus association. Just because a variable is associated with a particular outcome does not mean that it is the cause of the outcome. Today, we clearly know that carrying a lighter does not cause lung cancer. However, those who carry lighters are likely to smoke, which is a clear cause. Hence a lighter in this example is a confounding variable.

Back to the proposed link between temperature and heart attacks. There is a good chance that temperature is a confounding variable in this case. Colder temperatures also occur at the same times as snow and influenza. The risks of a heart attack increase after snowfall because of the extra exertion that is needed to shovel snow, especially when it is wet and heavy. Influenza causes inflammation, including in the coronary arteries, which increases the chance of a heart attack. It doesn’t look like the authors addressed these alternative hypotheses in their study.

So what are the two take-home messages? I’d argue that there is always more than meets the eye and you can’t believe everything you read, even if it comes from a reputable source.

Pet Food and Salmonella Poisoning

An interesting study was just published in Pediatrics, titled “Human Salmonella Infections Linked to Contaminated Dry Dog and Cat Food, 2006–2008.” This is important since roughly 1/3 of US households own cats and 1/3 of US households own dogs.

People tend to joke about the idea that “I’m from the government and I’m here to help.” In this case, that is true. A federal program called PulseNet helped identify this outbreak.

from Johansson et al. BMC Microbiology 2006 6:47

PulseNet is essentially a data warehouse where information is collected from pulsed field gel electrophoresis, which is commonly referred to as “DNA fingerprinting.” This process uses enzymes to cut apart DNA segments. These segments are placed in a gel and an electrical current is applied. These segments move at different speeds through the gel based on some of their physical characteristics. The idea is that two separate samples can be compared. If the patterns match, chances are that the samples came from the same strain of organism.

Without PulseNet, the chances of identifying the source of this outbreak (the pet food manufacturing plant) would have been challenging if not outright impossible. Sometimes your tax dollars are hard at work.

People typically associate salmonella with poultry and reptiles. However, as this study shows, there are other sources as well. The epidemiological data indicated that illness was primarily linked to children under two years of age, which makes sense because a lower dose of the organism is likely to cause disease.

The most interesting piece of this study though was that illness was also associated with pets being fed in the kitchen. The authors postulate that cross contamination played an important role. There was further evidence in that there were not cases reported among children who had put the pet food in their mouths. This seems to indicate that the contamination of other surfaces that were used for cooking allowed the bacteria to reproduce and have sufficient numbers to cause illness.

So what is the lesson from this? After you feed your pet, be sure to wash your hands. Good hygiene practices are once again the key to protecting you and your family from illness.

The Key to Protecting Yourself from Infection as a Patient

After reading my first two posts, someone asked what they could do to minimize their risk of getting an infection if they are hospitalized. The answer somewhat depends on the cause of the hospitalization, but there is one general principle that applies regardless of the purpose of the hospitalization.

The most important thing that can be done is to ensure that your caregivers are washing their hands. Ask them before they have any contact with you. This isn’t an offensive question, it’s for your own safety.

You may also see them using alcohol hand sanitizers. In most cases, that is actually preferable because it is more effective at killing microorganisms and has longer persistence than soap and water. In addition, there is some thinking that the antibacterial agent in most soaps (triclosan) may be a contributing factor that drives antibiotic resistance.

Either way, be sure that you ask. We need to create a culture where that is not only tolerated, but accepted practice. If a health care provider is offended by that, I would argue that they are in the wrong profession. If the whole point of medicine is to “first, do no harm,” this simple measure should be part of the norm. Would you expect anything different?

The Measure of a Man

Just a quick quote today. BTW, my posts are going to be apolitical. I’ll pick things that appeal to me from both the right and the left, so don’t think I’m favoring one side or another.

“The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.”
–Martin Luther King Jr. (1929-1968)

Self-Talk

Unless there is something really pressing in the news I think weekends will be generally dedicated to personal growth and development topics, humor, or just random rants. I might also limit myself to one post on the weekend to give myself a day off. There will be gaps as well if I’m too busy with other projects although I’ll probably make a quick comment as long as I have internet access each day.

Today I want to mention a book that was recommended to me a few months ago (thanks Dawn) around how we can reprogram our own thinking about ourselves. I just finished it last Friday.

I’ve had a number of friends discussing this topic in a general sense lately and it seems like a good one to share. The best thing for me has been how they have tried to give me some perspective on who I am in the world – that can be a very difficult thing to see. I guess it’s similar to a “can’t see the forest for the trees” type of problem. I really appreciate friends like that who help me see some of those truths instead of the goofy lies that run through my head. I think everyone has a number of those they tell themselves.

The book is What to Say When you Talk To Yourself by Shad Helmstetter. Part of the description of the book probably describes the problem it addresses better than I can. “We all talk to ourselves all of the time, usually without realizing it. And most of what we tell ourselves is negative, counterproductive and damaging, preventing us from enjoying a fulfilled and successful life.”

I’ll give you the core idea although I think the book is a must read. We tend to get trapped in being effective and growing because we are always in a conversation in our heads that “I’m not ________ enough to do that, I could never _________, who am I kidding, there’s no way I could _______” and so on. Before we even try to change ourselves, take on new goals, or accomplish tasks we often cripple ourselves if not outright doom ourselves to failure because of that little voice that keeps cropping up.

So why don’t we try to change the message of that voice? What if we could start having it tell us what we are capable of doing and letting it drive us to succeed and exceed what we thought was possible? The author makes a very convincing argument that it can be done and gives directions on how to change that voice and our subsequent thinking and gives the rationale for how it works from a psychological standpoint.

If you decide to tackle something like this I’d love to hear stories of what is happening, as would other people who read this. I think it could be very motivational. However, if you want to keep it private, I understand that as well. But be bold if you are up to it. Post some comments. Let everyone know what you are planning to do to change yourself and your life. Most importantly, let us know the results.

How Many Must Die? – Part 2

So how did we get to this point? Is health care delivery really that far behind in quality?

In April 2000, the Institute of Medicine issued a report titled “To Err Is Human: Building a Safer Health System.” This report detailed the incredible number of mistakes and adverse outcomes that occur in American health care. As one might expect, this sort of exposé had many detractors (JAMA. 2000 Jul 5;284(1):93-5).

Of course, it’s nearly impossible to completely remove errors when humans are a major part of the process. No matter how educated or skilled we are, mistakes are bound to occur. There is something in our nature though that seems to prevent us from admitting to making these mistakes and being transparent about them.

As an example, assume you are the parent of a child and your pediatrician makes a mistake. Don’t you think you should have a right to know? Most parents want this kind of disclosure (Arch Dis Child. 2010 Apr;95(4):286-90). Unfortunately, mistakes are often buried and not disclosed. This is even more likely when the pediatrician thinks the parent is less likely to find out about the error. (Arch Pediatr Adolesc Med. 2008 Oct;162(10):922-7).

Obviously, one of the things that works against disclosure is our litigious society. That seems like a rather pat answer though. Lawsuits may actually be more of a symptom of a deeper problem and not the primary cause of what is happening.

There are probably a couple of factors that are playing roles in the health care quality problem.

First, health care has become incredibly complicated. It isn’t just due to the types of care provided using advanced technology but also the business of health care is a massive tangle. If you don’t think so, just try to contact a few hospitals and see if you can find out the cost of something as simple as an appendectomy. It’s unlikely that you will be able to get a straight answer. Some of this is legitimate because of other medical conditions that may come into play because of the cost of care. The crazier part of it though is that the cost isn’t set – it’s completely influenced by the prices negotiated by your health insurance provider. Even if you need to go into an emergency room to obtain care, it’s unlikely that anyone you come in contact with would have any clue as to how much your visit is going to cost you.

This complicated system drives health care organizations into the second problem, structures that are very resistant to change. This is even more evident as organizations become larger and larger. Not only is there a systemic problem, but the large scale of organizations and the multiple approvals needed for projects turns health care systems into institutions with all of the speed and nimble handling of a glacier.

This problem is even more apparent when you look at how long it takes for a new pharmaceutical agent or medical device to gain wide acceptance in the marketplace. Granted, there is some reluctance for providers to become early adopters of new technology until it has stood the test of time. Guess how long though it takes for widespread adoption of new medicine or technology. Do you think it might be five or ten years? Try again. The average is 19 years.

Personally, I use the “loved ones test” when I look at new technology. Essentially, if there is enough convincing medical literature suggesting benefit, I ask myself “would I want this for one of my loved ones?” If the answer is yes, it’s probably a pretty good technology to at least trial if not outright adopt.

This resistance to change might be one of the biggest barriers to improving quality in health care. It’s both a problem of organization size and inertia along with something that is much more sinister and not discussed –  the problems of power, ego, and self-interest. On the surface nobody will admit to this, but I have seen these themes crop up over and over again. For example, I worked at a large metropolitan hospital and wanted to empower patients to ask their caregivers if they had washed their hands. Seems like a simple thing, doesn’t it? Obviously it wasn’t. I had to bring the idea before the nursing union which adamantly blocked the process. I had never dealt with the union before and I wasn’t sure why the senior administration wouldn’t tackle this issue with them since they were responsible for union negotiation issues.

This whole problem reminds me of a book I read that was recommended to me by a friend years ago (thanks Jennifer). The book is People of the Lie: The Hope of Healing Human Evil by M. Scott Peck. In it, Peck gives a number of case studies of individuals who appeared normal on the outside but clearly had problems of evil within their cores. Maybe that’s something that our superficial culture has spawned. Later in the book though, he discusses corporate evil, which is one of the most fascinating topics and arguments I’ve ever read. He conducts an organizational case study of the Mỹ Lai Massacre by a unit of the US Army during the Vietnam War. He poses the question “How is it that approximately five hundred men, the majority of whom were not evil as individuals, could all have participated in an act as monstrously evil as that at MyLai?” The answer to that question has fascinated me since I read the book years ago. The entire discussion on the topic of organizational evil is really a must-read for anyone interested in organizational culture.

So are health care organizations evil? Usually not. Do they have evil characteristics? Sometimes. You don’t have to look far to find ones who blatantly put profit over safety. For example, in 2008 it was discovered that an endoscopy clinic in Nevada was reusing syringes and medication vials in attempt to cut costs. The incident led to the largest public health investigation (40,000 people) in US history. I’m board-certified in infection prevention and was dumbfounded to hear that something like this occurred with so many patients at risk and so many providers at fault. This is exactly the kind of group think that Peck was referring to in his book.

There are other problems that occur in the health care system as well. For example, I’ve seen instances where physicians are allowed to make decisions around preventative measures in a hospital that would potentially impact the volume of work they would see in their private practice. In other industries, that would be considered a major conflict of interest but that problem didn’t even seem to make anyone’s radar because it was the normal way of doing things. That thinking and process must change if we are to see improvements in health care quality.

So here is the real question. Why is it that health care is following the lead around manufacturing processes (the Toyota Production System in order to learn to be lean, Six Sigma from Motorola to reduce variability and improve quality) or simple things like preflight checklists in the airline industry to ensure safety? Health care is making progress in these areas but shouldn’t health care be the leader instead of the manufacturing and transportation industries? Where did we go wrong?

How Many Must Die before We Take Things Seriously?

In 2002, it was reported that almost 100,000 Americans die every year from health care associated infections. “The estimated deaths associated with HAIs in U.S. hospitals were 98,987: of these, 35,967 were for pneumonia, 30,665 for bloodstream infections, 13,088 for urinary tract infections, 8,205 for surgical site infections, and 11,062 for infections of other sites.” (Public Health Rep. 2007 Mar-Apr;122(2):160-6.)

So is 100,000 deaths a big deal? Isn’t that just one of the risks of entering the health care environment? Let’s use the airline industry for comparison.

The Boeing 767 went into operation in 1980. Over 900 of them have been placed in service. There are a number of configurations that would allow them to seat between 181 to 375 passengers. Let’s assume though that they are designed for 274 to keep the math simple.

There have been only six notable events with these aircraft that have resulted in deaths. The only ones that occurred in the US were the two aircraft used in the World Trade Center attacks on 9/11/01. These are very safe aircraft.

So how many of these planes would need to go down killing all aboard to match the death rates from health care associated infections in the US? 100,000 deaths could be achieved by one of these planes crashing every day. Are you shocked? Good.

Think of what would happen if a 767 crashed somewhere in the US three or four days in a row. How long do you think it would take for the entire fleet with every carrier to be grounded by the FAA? Days? Hours?

So why is it that we let the health care plane crash every day like this? Is there anything we can do to stop it? Why isn’t there a massive cry for reform? Why do providers seem to think the problem belongs to someone else?
