Why Do Doctors Wear White Coats?Because they say "science."
Posted Friday, June 19, 2009, at 6:42 PM ET
The American Medical Association voted Tuesday on a resolution that would recommend hospitals ban doctors' iconic white lab coats, citing evidence that the garment contributes to the spread of infection. (The resolution was referred to a panel for further consideration.)* Indeed, a number of studies have shown that the coats harbor potentially harmful bacteria (and may cause "white coat hypertension"). If white coats are so bad, why do doctors still wear them?
Because a white lab coat says "I am a scientific healer." The knee-length coat in medicine crossed over from the laboratory sciences at the turn of the 20th century. Before that time, medicine was generally seen as the haphazard province of quacks and frauds, and physicians wore street clothes even in the operating room. As the field developed into a respected branch of applied science in the early 1900s, doctors adopted the costume of the laboratory as a way of bolstering their scientific credibility.

StumbleUponIn pre-white-coat times, physicians used primitive tools and techniques and had little formal training. (Medical school could be finished in a year.) Early doctors competed for legitimacy (and patients) with other healing arts like homeopathy and medical eclecticism. But the development of antiseptics and anesthesia, among other things, demonstrated the exceptional power of science to improve health. Doctors strove to become more scientific, in practice and in dress. The lab coat served both purposes by providing a (supposedly) sterile work environment and soothing patients with its air of scientific authority. The traditional lab coat was beige, but doctors adopted white because the color symbolizes life and purity. (In earlier times, doctors were more likely to wear black, in keeping with the high mortality rates seen at hospitals. The nuns who served as nurses often wore black habits.) By 1915, physicians working in hospitals had for the most part switched from street clothes to white coats and pants.
With their scientific bona fides firmly in place, doctors today are divided on the white-coat question. Supporters say the coat instills docs with a humbling sense of responsibility and puts patients at ease, while detractors see it as an alienating symbol of medical hubris. More than 100 medical schools host "white coat ceremonies" where first-year med students are outfitted with shortened versions of the white coat, and the coats are ubiquitous at large teaching hospitals where they help differentiate between doctors and students. However, doctors in smaller hospitals and private practice are more likely to wear regular clothes. A recent study suggests that only 1 in 8 doctors actually sport a white coat at work. Perhaps the most ardent supporters of the garment are patients: In one study, 56 percent of those surveyed believed doctors should wear coats, compared with only 24 percent of doctors. (Elderly people tend to be most supportive of the white coat.) Another study found that patients were much more likely to trust a doctor if they were wearing a white coat than if they were in scrubs.
If hospitals followed the AMA resolution and banned the white coat, what would doctors wear? The Scottish National Health Service outlawed white coats in 2008 and instituted a uniform of color-coded scrubs for all medical personnel. The Mayo Clinic doesn't allow white coats; their doctors wear business attire.

Correction, June 22, 2009: The original version incorrectly said the American Medical Association voted last Tuesday to recommend that hospitals ban doctors' white coats. AMA members voted to refer the resolution to a panel for further consideration. (Return to the corrected sentence.)

White coats represent authority and confer more respect for doctors among older patients. However, pediatricians rarely wear them because children learn to associate white coats with unpleasant experiences. And white coats are more important in the east than the in the west. I'm a physician in California and "white coat ceremonies" are not part of the medical tradition here. It is true that the pockets are handy, but one can learn to live without them. White coats really aren't essential. Scrubs are much more efficient. But it is true that health care providers (broadly) don't change them as frequently as should happen.

I'm a doctor and I used to dislike lab coats -- what they stood for and how dirty they were. The standard at my work site right now is a long gray coat for attendings, white for residents. While I never thought I'd want to wear a lab coat during patient care, it serves many purposes. A lot of professional clothes for women have no or non-functional pockets. The coat gives me a way to carry the pager, the blackberry, pens, various notes/stampers/id's that my male colleagues stuff into their pants pockets or clip to their belt. Also, it protects my expensive clothes against the spilled fluids (bodily and otherwise) that I come across in the course of my clinical day: just yesterday my lab coat came between me and a poorly capped bottle of betadine. Finally, as a young woman, the coat helps differentiate me to patients and hospital staff as an attending, especially when in the required scrubs on the OB floor. Otherwise, I am usually addressed as a nurse. While I do not find this offensive, it is tiring to clarify and then have the usual awkward conversation as to why the person didn't guess I was a doctor.
