A hospital patient recovering from an illness or medical condition is an everyday occurrence. So, alas, is the chance -- estimated at 1 in 20 -- of that patient contracting an infection during the hospital stay.

These days, ordinary germs aren't the only problem for health care professionals. Even more disturbing for them is the tendency for microbes -- disease-causing organisms -- to mutate and become resistant to antibiotics.

All of which makes a hospital stay for the most vulnerable people in the population a risky business. There is even a special word to describe that risk. "Nosocomial," an adjective, refers specifically to infections contracted as a result of being hospitalized.

The statistics that follow in the wake of this trend are alarming. Such infections are said to cause 90,000 deaths annually, and estimates on the cost of treating survivors amount to more than $4.5 billion.

The situation is bad enough that hospitals such as Washington Hospital Center, the largest in Washington, have instituted poster campaigns to remind employees about the frontline defense for protecting themselves and patients: hand washing. Six months ago, the hospital began putting that message alongside photographs of familiar faces -- such as the head of the surgical intensive care unit and the hospital's director -- in prominent places throughout the building.

The effort has overtones of elementary school, but such methods show the determination of medical institutions to try every means to control infection rates. It sometimes seems that the microbes mutate as fast as drugs are developed to curtail them.

One of these bad bugs, known familiarly to health care workers as MRSA (methicillin-resistant staphylococcus aureus), is particularly difficult to stamp out. Worse, it can cause life-threatening infections. The antibiotic Vancomycin is the drug of choice when treating MRSA infections, according to the Johns Hopkins Medicine Web site, which tells readers that hand hygiene is the most important strategy in preventing transmission.

Various government and nonprofit institutions are involved in the campaign, among them, the Infectious Diseases Society of America, the Society for Healthcare Epidemiologists of America, and, of course, the U.S. government's Centers for Disease Control and Prevention.

The CDC recently awarded $10 million to five medical centers to research new approaches to reducing infections in health care settings. Seven states in the past four years have passed legislation mandating the reporting of infections.

"I can't imagine there isn't any hospital not working on the issues," says Nancy Donegan, director of infection control at Washington Hospital Center. Her department has four infection-control practitioners among a full-time staff of six. "Unfortunately, we are all stuck with some of the same behaviors to help this"-- behaviors that include occasional laxity in observing some of the more common-sense measures.
