Has the Hawthorne Effect Affected You? The Answer is Yes.

Here is a reality of human behavior. Folks behave differently when they know they are being watched. Consider two examples that we have all seen. We are sitting in the driver’s seat of our parked car. The driver in the adjacent car sees us and then opens his door with particular care so as to avoid dinging us. We wonder what his car door action might have been had our own car been empty. Similarly, in most business scenarios, I suspect that the staff perform at a higher level when the boss is around.

This phenomenon is referred to as the Hawthorne Effect, whose name derives from some industrial research done in the Hawthorne suburb of Chicago nearly a century ago.

Do you behave the same way when someone's watching?

And yes, this truth exists also in the medical profession.

Consider the following proposed studies and if the results might be distorted by the Hawthorne Effect.

The Chairman of the Department of Surgery announces an initiative to improve patient satisfaction. Surveys have indicated that patients #1 gripe is being kept waiting for their appointments. The chairman announces that physician punctuality will be monitored over the next 8 weeks to assess the extent of the behavior and who the outliers are.
A hospital system is disturbed by an increase in breast cancer diagnoses over the past 6 months. There is a concern that physicians may not be performing breast examinations adequately or at all. The medical staff is informed that all female patients will be surveyed asking if they were examined and taught of the importance of breast self-examination.
An orthopedic department wants to assess how well it is controlling post-operative pain. Trained nurses will be interviewing all patients for 5 days after surgery. Afterwards, the data will be shared with the department and with individual practitioners.

Clearly, the potential of a Hawthorne Effect in all of the above examples is self-evident. This effect extends beyond medicine into all spheres of society. It’s a psychological phenomenon and we need to be aware of it. As an example, when I am reading a medical study that shows that an action benefits patients, is the action responsible or are the patients behaving differently because they know they are being studied? This can be rather tricky and if you’re not tightly tuned in, the Hawthorne Effect will blow right past you.

Of course, managers and leaders can utilize the Hawthorne Effect purposefully just to influence behavior. They may announce a new ‘research study’ when the intent is really to modify behavior.

Is this all just psychobabble? Does your own behavior change when there’s another set of eyes on you?

Why Most Doctors Choose Employment

Increasingly, physicians today are employed and most of them willingly so. The advantages of this employment model, which I will highlight below, appeal to the current and emerging generations of physicians and medical professionals. In addition, the alternatives to direct employment are scarce, although they do exist. Private practice gastroenterology practices in Cleveland, for example, are increasingly rare sightings. Another practice model is gaining ground rapidly on the medical landscape. Private equity (PE) firms have been purchasing medical practices who are in need of capital and management oversight. PE can provide services efficiently as they may be serving multiple practices and have economies of scale. While these physicians technically have authority over all medical decisions, the PE partners can exert behavioral influences on physicians which can be ethically problematic. For example, if the PE folks reduce non-medical overhead, this may very directly affe

Should Doctors Wear White Coats?

Many professions can be easily identified by their uniforms or state of dress. Consider how easy it is for us to identify a policeman, a judge, a baseball player, a housekeeper, a chef, or a soldier. There must be a reason why so many professions require a uniform. Presumably, it is to create team spirit among colleagues and to communicate a message to the clientele. It certainly doesn’t enhance professional performance. For instance, do we think if a judge ditches the robe and is wearing jeans and a T-shirt, that he or she cannot issue sage rulings? If members of a baseball team showed up dressed in comfortable street clothes, would they commit more errors or achieve fewer hits? The medical profession for most of its existence has had its own uniform. Male doctors donned a shirt and tie and all doctors wore the iconic white coat. The stated reason was that this created an aura of professionalism that inspired confidence in patients and their families. Indeed, even today

Electronic Medical Records vs Physicians: Not a Fair Fight!

Each work day, I enter the chamber of horrors also known as the electronic medical record (EMR). I’ve endured several versions of this torture over the years, monstrosities that were designed more to appeal to the needs of billers and coders than physicians. Make sense? I will admit that my current EMR, called Epic, is more physician-friendly than prior competitors, but it remains a formidable adversary. And it’s not a fair fight. You might be a great chess player, but odds are that you will not vanquish a computer adversary armed with artificial intelligence. I have a competitive advantage over many other physician contestants in the battle of Man vs Machine. I can type well and can do so while maintaining eye contact with the patient. You must think I am a magician or a savant. While this may be true, the birth of my advanced digital skills started decades ago. (As an aside, digital competence is essential for gastroenterologists.) During college, I worked as a secretary
