In the ongoing war of humans vs. disease-causing bacteria, the bugs are gaining the upper hand. Deadly and unrelenting, they’re becoming more and more difficult to kill. You might think of hospitals as sterile safety zones in that battle. But in truth, they are ground zero for the invasion.

Though infections are just one measure of a hospital’s safety record, they’re an important one. Every year an estimated 648,000 people in the U.S. develop infections during a hospital stay, and about 75,000 die with them, according to the Centers for Disease Control and Prevention (CDC). That’s more than twice the number of people who die each year in car crashes. And many of those illnesses and deaths can be traced back to the use of antibiotics, the very drugs that are supposed to fight the infections.

Terry Otey appears to be one casualty in that ongoing battle. Three years ago, a few weeks after an overnight stay for back surgery at Providence Regional Medical Center in Everett, Wash., he went to the emergency room vomiting, dizzy, and with excruciating back pain. Bacteria known as MRSA (methicillin-resistant staphylococcus aureus) had taken hold in his surgical incision and quickly spread to his heart. He died in the hospital about three months later, following a cascade of serious health problems. “He just wanted to ease his back pain enough to play golf,” says his sister, Deborah Bussell.

Kellie Pearson, 49, a farmer in northern California, says she encountered a different kind of bug after having heart surgery last April. Her doctors prescribed an antibiotic in the hopes that it would prevent a postsurgical infection. Instead the drug killed off healthy bacteria in her body, and another germ, C. diff (clostridium difficile), swooped in, causing diarrhea so severe that she had to stay in the hospital an additional five days until doctors could rein in the potentially deadly infection.

She recovered but soon realized that she wasn’t the only patient suffering. “When I was able to walk down the hall in the hospital,” she says, “I was horrified to see room after room with C. diff caution signs on their doors warning that the patients inside, like me, had been infected.”

“Hospitals can be hot spots for infections and can sometimes amplify spread,” says Tom Frieden, M.D., director of the CDC. “Patients with serious infections are near sick and vulnerable patients—all cared for by the same health care workers sometimes using shared equipment.”

Making the situation even more dangerous is the widespread, inappropriate use of antibiotics that’s common in hospitals, which encourages the growth of “superbugs” that are immune to the drugs and kills off patients’ protective bacteria.

It’s “the perfect storm” for infections to develop and spread, says Arjun Srinivasan, M.D., who oversees the CDC’s efforts to prevent hospital-acquired infections. “We’ve reached the point where patients are dying of infections in hospitals that we have no antibiotics to treat.”

But there’s hopeful news: Some hospitals are taking steps to reduce infections and end inappropriate antibiotic use. “But others have made little effort,” Srinivasan says.

Consumer Reports’ hospital Ratings shine a spotlight on the problem. For the first time ever, those Ratings include information on MRSA and C. diff infections, based on data that hospitals submit to the CDC. And the results are sobering.

Three out of 10 hospitals in our Ratings got one of our two lowest scores for keeping C. diff in check; four out of 10 got low marks for avoiding MRSA. Only 6 percent of hospitals scored well against both infections.

“Hospitals need to stop infecting their patients,” says Doris Peter, Ph.D., director of the Consumer Reports Health Ratings Center. “Until they do, patients need to be on high alert whenever they enter a hospital, even as visitors.”

But there’s plenty that hospitals can do to stop the spread of deadly, sometimes resistant infections, and there are steps you can take as well to keep you and your family safe.

We are focusing on C. diff and MRSA for two important reasons.

First, the infections are common and deadly. More than 8,000 patients each year are killed by MRSA; almost 60,000 are sickened by the infections. The bacteria often find their way into patients’ bodies through the lines and tubes that doctors use to deliver medication and nutrition to patients, or via surgical incisions, as happened to Terry Otey.

C. diff is an even bigger concern. Kellie Pearson is one of the 290,000 Americans sickened by the bacteria in a hospital or other health care facility each year. She was lucky: At least 27,000 people in the U.S. die with those infections annually.

Second, poor MRSA or C. diff rates can be a red flag that a hospital isn’t following best practices in preventing infections and prescribing antibiotics. That could not only allow C. diff and MRSA to spread but also turn the hospital into a breeding ground for other resistant infections that are even more difficult to treat.

For example, as dangerous as MRSA is, an infection can be cured if it is treated promptly with vancomycin, long held out as an “antibiotic of last resort.” But, in part because that drug is now so often used in hospitals, another resistant strain of bacteria—vancomycin-resistant staphylococcus aureus, or VRSA—is emerging. “VRSA infections pose special challenges; they can be even more difficult to treat than MRSA,” Srinivasan says.

To earn our very top rating in preventing MRSA or C. diff, a hospital has to report zero infections—an admittedly high bar. Still, 322 hospitals across the country were able to achieve that level in our MRSA ratings, and 357 accomplished it for C. diff, showing that it is possible. (Experts say some hospitals might game the system. Read more about how hospitals fudge the numbers, and help us identify those that might not accurately report infections.)

More hospitals were able to earn either of our two highest ratings—indicating that they reported either zero infections or did much better than predicted compared with similar hospitals: more than 623 hospitals received high marks for MRSA, and 917 did so for C. diff.

Hospitals really begin to distinguish themselves when they earn high ratings against both infections: 105 hospitals succeeded in that. Even better, some hospitals excel against not only MRSA and C. diff but also other infections that the CDC tracks and that are in our hospital Ratings. Those include surgical-site infections and infections linked to urinary catheters or central-line catheters, large tubes that provide medication and nutrition.

“Hospitals that do well against infections across the board have figured something out and deserve special mention,” Peter says. Only 9 hospitals in the country—those featured in the “Highest-Rated in Infection Prevention” chart earned that high honor.

You won’t find any familiar, big-name hospitals on that top-performing list. In fact, several high-profile hospitals got lower ratings against MRSA, C. diff, or both, including the Cleveland Clinic in Cleveland, Johns Hopkins Hospital in Baltimore, Mount Sinai Hospital in New York City, and Ronald Reagan University of California Los Angeles Medical Center.

Those are all large teaching hospitals in urban areas, which in our analysis did not do as well as nonteaching hospitals of similar sizes in similar settings. That could be because teaching hospitals may do a better job of reporting infections. Or, as a representative for Ronald Reagan UCLA Medical Center told us, they may see sicker patients or have more patients undergoing complex procedures.

Although the CDC adjusts the data to account for some of those factors, teaching hospitals tend to perform worse. For example, only 6 percent of teaching hospitals received one of our two top scores against C. diff, compared with 14 percent of similar nonteaching hospitals.

“Yes, teaching hospitals face special challenges. But they are also supposed to be places where we identify best practices and put them to work,” says Lisa McGiffert, director of the Consumer Reports Safe Patient Project. “Obviously, that is not happening as well as it should.”

Larger hospitals also tended to do worse in our Ratings. That could be because patients in smaller hospitals are less likely to be exposed to infections. But some larger hospitals managed to do a good job avoiding infections. Case in point: Harlem Hospital Center in New York City earned high ratings against MRSA and C. diff. Or consider Northwest Texas Healthcare System in Amarillo, Texas. It made it onto our list of top hospitals in the prevention of all of the infections included in our Ratings.

Good hospitals focus on the basics:

Use antibiotics wisely

Almost half of hospital patients are prescribed at least one antibiotic, Srinivasan says, but “up to half the time the drug is inappropriate.” To combat antibiotic misuse, many good hospitals have “antibiotic stewardship” programs, often headed by a pharmacist trained in infectious disease, to make sure that patients get the right drug, at the right time, in the right dose.

Such programs often monitor the use of broad-spectrum antibiotics. Doctors at some hospitals use three times more of those all-purpose bug killers than others. Reducing broad-spectrum prescriptions by 30 percent would “cut hospital rates of C. diff by more than 25 percent, plus reduce antibiotic resistance,” says Clifford McDonald, M.D., a CDC epidemiologist.

Keep it clean

C. diff and MRSA can live on surfaces for days and can be passed from person to person on hospital equipment or the hands of health care workers. To prevent that, hospitals must be kept scrupulously clean. “Infection control is all about the basics, starting with hand hygiene,” says Christine Candio, president and CEO of St. Luke’s Hospital in Chesterfield, Mo., which earned higher Ratings against both MRSA and C. diff.

She reminds patients, “it’s your right to ask” staff to wash up. In fact, fastidious hand washing slashes rates of C. diff, MRSA, and other infections. St. Luke’s also “prioritizes cleanliness,” in some cases exceeding infection-control guidelines—cleaning the rooms of C. diff patients twice daily, for example, and replacing curtains between patients.

Steps such as those, plus federal mandates for some public reporting of infections data, have already led to reduced rates of certain infections. Still, McGiffert says hospitals need to do more:

• Consistently follow the established protocols for managing superbug infections, such as using protections including gowns, masks, and gloves by all staff.
• Be held financially accountable. Already, hospitals in the bottom 25 percent of the government’s data at preventing certain complications now have Medicare payments docked 1 percent. But they should also have to cover all costs of treating infections patients pick up during their stay.
• Have an antibiotic stewardship program. That should include mandatory reporting of antibiotic use to the CDC.
• Accurately report how many infections patients get in the hospital. And the government should validate those reports.
• Be transparent about infection rates. For instance, Cleveland Clinic acknowledges its below-average performance in C. diff prevention on its website. “That’s refreshingly candid,” Peter says.
• Promptly report outbreaks to patients, as well as to state and federal health authorities. Those agencies should inform the public so that patients can know the risks before they check into the hospital.
