The Disturbing Truth About Doctors and Your Medical Safety

By Atul Gawande, AlterNet. Posted May 18, 2007.

One ordinary December day, I took a tour of my hospital with Deborah Yokoe, an infectious disease specialist, and Susan Marino, a microbiologist. They work in our hospital's infection-control unit. Their full-time job, and that of three others in the unit, is to stop the spread of infection in the hospital. This is not flashy work, and they are not flashy people. Yokoe is forty-five years old, gentle voiced, and dimpled. She wears sneakers at work. Marino is in her fifties and reserved by nature. But they have coped with influenza epidemics, Legionnaires' disease, fatal bacterial meningitis, and, just a few months before, a case that, according to the patient's brain-biopsy results, might have been Creutzfeld-Jakob disease -- a nightmare, not only because it is incurable and fatal but also because the infectious agent that causes it, known as a prion, cannot be killed by usual heat-sterilization procedures.

By the time the results came back, the neurosurgeon's brain-biopsy instruments might have transferred the disease to other patients, but infection-control team members tracked the instruments down in time and had them chemically sterilized. Yokoe and Marino have seen measles, the plague, and rabbit fever (which is caused by a bacterium that is extraordinarily contagious in hospital laboratories and feared as a bioterrorist weapon). They once instigated a nationwide recall of frozen strawberries, having traced a hepatitis A outbreak to a batch served at an ice cream social. Recently at large in the hospital, they told me, have been a rotavirus, a Norwalk virus, several strains of Pseudomonas bacteria, a superresistant Klebsiella, and the ubiquitous scourges of modern hospitals -- resistant Staphylococcus aureus and Enterococcus faecalis, which are a frequent cause of pneumonias, wound infections, and bloodstream infections.

Each year, according to the U.S. Centers for Disease Control, two million Americans acquire an infection while they are in the hospital. Ninety thousand die of that infection. The hardest part of the infection-control team's job, Yokoe says, is not coping with the variety of contagions they encounter or the panic that sometimes occurs among patients and staff. Instead, their greatest difficulty is getting clinicians like me to do the one thing that consistently halts the spread of infections: wash our hands.

There isn't much they haven't tried. Walking about the surgical floors where I admit my patients, Yokoe and Marino showed me the admonishing signs they have posted, the sinks they have repositioned, the new ones they have installed. They have made some sinks automated. They have bought special five-thousand-dollar "precaution carts" that store everything for washing up, gloving, and gowning in one ergonomic, portable, and aesthetically pleasing package. They have given away free movie tickets to the hospital units with the best compliance. They have issued hygiene report cards. Yet still, we have not mended our ways. Our hospital's statistics show what studies everywhere else have shown -- that we doctors and nurses wash our hands one-third to one-half as often as we are supposed to. Having shaken hands with a sniffling patient, pulled a sticky dressing off someone's wound, pressed a stethoscope against a sweating chest, most of us do little more than wipe our hands on our white coats and move on -- to see the next patient, to scribble a note in the chart, to grab some lunch.

This is, embarrassingly, nothing new: In 1847, at the age of twenty-eight, the Viennese obstetrician Ignac Semmelweis famously deduced that, by not washing their hands consistently or well enough, doctors were themselves to blame for childbed fever. Childbed fever, also known as puerperal fever, was the leading cause of maternal death in childbirth in the era before antibiotics (and before the recognition that germs are the agents of infectious disease). It is a bacterial infection -- most commonly caused by Streptococcus, the same bacteria that causes strep throat -- that ascends through the vagina to the uterus after childbirth. Out of three thousand mothers who delivered babies at the hospital where Semmelweis worked, six hundred or more died of the disease each year -- a horrifying 20 percent maternal death rate. Of mothers delivering at home, only 1 percent died.
