High compliance rates linked to lower incidences, while CDC pledges $67 million to help hospitals
This may not come as a surprise to many people in the healthcare industry, but when workers wash their hands more often, it often makes for a healthier environment.
Now, it seems the CDC has proof. A recent study conducted by the agency, and published in the September 2016 issue of the Emerging Infectious Diseases journal, found that increasing hand hygiene compliance from high to very high could have a positive effect on healthcare-associated infections (HAI).
During the 17-month period of the study, the research team at the University of North Carolina Health Care Center made 140,000 unique hand hygiene observations as the health system increased its compliance from 82.6% to 95.9%.
Researchers say they “noted a significant increase in overall hand hygiene compliance rate and a significantly decreased overall HAI rate, supported by 197 fewer infections and an estimated 22 fewer deaths,” according to an article published by Healthcare Facilities Management magazine.
The study’s findings come at a time when the CDC also is pledging to spend $67 million nationwide to help state health departments battle antibiotic resistance and other patient safety threats, including HAIs, which have become a major problem in U.S. hospitals.
The new funding for antibiotic resistance will help support the founding of seven new regional laboratories with specialized capabilities for rapid detection and identification of emerging antibiotic-resistant threats.
According to a CDC release, the funds, which became available in August 2016, will be distributed to all 50 state health departments, six local health departments in Chicago, the District of Columbia, Houston, Los Angeles County, New York City, Philadelphia, and Puerto Rico.
The money also will expand state capability to track infections in healthcare settings, protect patients through targeted prevention, and increase coordination across medical care. In addition, the money will help conduct foodborne disease tracking, investigation and prevention, including increased support for the PulseNet and OutbreakNet systems and for the Integrated Food Safety Centers of Excellence, plus continued support for the National Antimicrobial Resistance Monitoring System.
The CDC also will provide support teams in nine health departments for rapid response activities designed to quickly identify and respond to the threat of antibiotic-resistant gonorrhea in the U.S.
Hospitals have been trying all sorts of tactics to try to get workers—especially busy nurses and physicians on the go—to do a better job of washing their hands after seeing patients or after personal tasks during the day. It becomes easy to forget sometimes, and over time many hundreds of missed hand washing “opportunities,” as they are referred to, can add up to a much bigger chance that your facility will fall victim to a deadly infection such as MRSA or C. difficile. Nationally, the hand washing compliance rate is only about 45%.
See the sidebar below for advice from healthcare safety experts on how you can improve hand hygiene in your facility.
Many hospitals use what are termed “secret shoppers,” usually infection preventionists or other experts who come in to casually watch employees during the course of a day to track hand washing compliance rates.
The problem with this tactic, some experts say, is that those being watched usually can figure it out pretty quickly and adjust their habits accordingly. What’s more, observers can only watch so many people and can’t get an accurate count of how many “opportunities” are seized over a longer period of time. For this reason, compliance rates in these facilities still only range around the 80% mark.

It turns out that the WHO might know more about effective hand washing techniques than the CDC, according to a new report.
The report, published last April 6 in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA), found that a six-step hand washing technique developed by the WHO is more effective at killing bacteria than the CDC’s three-step method.
Jacqui Reilly, PhD, professor of infection prevention and control at Glasgow Caledonian University in Scotland, was one of the lead authors comparing the WHO’s and the CDC’s hand washing methods. She told HealthLeaders Media in April 2016 that the WHO’s method washes 67% of the bacterial load from a person’s hand, while the CDC’s method only washes off 35%. The trade-off is that the WHO method takes 42.5 seconds to do properly, while the CDC method only takes 35 seconds. Reilly and her team compared the bacterial load on the hands of 42 physicians and 78 nurses after taking care of patients. Researchers documented how much bacteria were left over after each participant had washed their hands, either using the CDC or the WHO method.
“Hand hygiene is the most important intervention we can all do to prevent disease and infection,” said Reilly.
The need for good hand washing hygiene in healthcare is not new, but the struggle to get healthcare workers to not only do it, but do it right, is constant.
And necessary. According to WHO officials, many healthcare-associated infections (HAI) are preventable through good hand hygiene. Hand washing is a cheap and effective method of preventing the spread of antibiotic resistant diseases, which are expected to annually kill 10 million people worldwide by 2050.
However, the type of hand washing method is a secondary concern compared to a bigger issue; getting healthcare workers to wash their hands at all. In a different study published in the April issue of the American Journal of Infection Control (AJIC), researchers secretly chronicled 330 hand hygiene observations at 15 different facilities. The AJIC researchers found that a frighteningly low 37% of the staff observed washed their hands.
What is the proper way to wash your hands?
Reilly says her study found that the WHO’s six-step hand washing technique is better at cleaning one’s hands than the CDC’s three-step process. The WHO’s method states that after applying soap or sanitizer to one’s hands:
- Rub your palms together.
- Rub each palm front to back over the back of the other hand, interlacing fingers.
- Twist your palms with fingers interlaced, and rub between fingers.
- Interlock your fingers (thumbs should be on opposite sides) and twist again, this time with the backs of fingers against palms.
- Clasp your left thumb in your right hand and move thumb in circular motion—then switch thumbs.
- Press your right fingers together and rub them in a circular motion on your left palm, then switch.
“The uptake of this six-step technique, or any other hand hygiene technique, is not measured at the international level, although many countries do measure hand hygiene compliance in healthcare settings,” Reilly said. She continued to say that some countries, such as the U.S., have promoted a simpler process historically which only involves three steps:
- Apply the sanitizer to one palm.
- Rub both palms together.
- Rub product over your hands until dry.
Reilly says that the WHO endorses several multi-modal campaigns focusing on improving hand hygiene compliance by healthcare workers. She recommends that those who want to learn more about maintaining hand hygiene compliance visit the WHO guidelines and guidance on the measure.
Experts offer advice
Some healthcare experts say that while healthcare workers sometimes fall out of the practice of washing their hands, they’ll return to proper measures if prompted.
“The excuse of being too busy is not acceptable,” says Linda Gylland, QLS, MLS (ASCP), lab safety officer at Sanford Health in Fargo, North Dakota. “The excuse of ‘I will wear gloves anyway so don’t need to wash my hands,’ is also unacceptable. Hand washing is to be done before and after gloving. The excuse of ‘it’s hard on my hands’ is also unacceptable. There are great lotions available and options for hand sanitizers that actually lubricate your hands and feel good.”
While her facility’s goal for hand hygiene compliance is 95%, she says they’ve only managed to achieve 75% overall compliance.
“Our laboratories typically are very good with hand washing since we all wear gloves most of the time and know we are required to wash hands before and after glove removal and when leaving the lab,” she says. “We know the pathogens we are working with and do not care to take them home with us.”
Dan Scungio, MT (ASCP), SLS, the laboratory safety officer for the Sentara Healthcare system in Virginia, says that people often don’t understand the consequences of poor hand hygiene. He also places some of the blame on a lack of enforcement in healthcare facilities.
“I think it’s a difficult area for compliance for a lot of reasons, one [being] we don’t always make it easy for people to comply,” he says. “We don’t always educate staff and physicians and others in the facility the way we need to about the importance of hand hygiene. It’s something we hear about in everyday life, we hear about it in commercials, we hear about it at home, school, wherever. But there’s no special emphasis placed on it in the healthcare setting, and there really should be. Hospital-acquired infections can be pretty deadly.”
Hand hygiene is a high priority for Sentara Healthcare, he says, with a goal of achieving 100% compliance organizationwide. He notes that they’ve had some success toward that goal, with two of their hospitals becoming the first in the world to receive the DNV’s Managing Infectious Risks certification.
“It was known nationally that hand hygiene compliance in healthcare facilities was not great,” he says. “So we wanted to establish a program here and have been talking about it ever since. It’s not fallen off the radar screen here.”
Scungio notes that some departments struggle more with hand washing compliance than others. Emergency departments are one of the biggest offenders due to the extra pressures they face.
“In the emergency department where they live in a world of chaos and sometimes because of that world they do things to cut corners,” he says. “And they’re looking at it as, ‘I’m doing this for the patient.’ But don’t realize they may be harming the patient. That’s not particular to the emergency department but it does happen a lot there.”
Education and awareness
Scungio says that for any facility trying to improve its hand hygiene compliance, the first step is always education and awareness. Unless staff and visitors understand why hand hygiene is important and why the facility is going at lengths to enforce it, subsequent steps won’t work.
Facilities should do more with storytelling about hand hygiene cases, he says. There are a lot of true stories out there about HAIs, ones that have caused patient deaths and harm, adds Scungio. By giving staff members some of these stories and explaining how they happened and how they could’ve been prevented, it can make hand hygiene become a higher priority.
“Another thing we can do is to inform the public about our intent,” he says. “We actually have posters that say, ‘If you see your healthcare worker not washing their hands before they come to work with you, you make sure to tell them to wash their hands.’ ”
Gylland says Sanford’s hand hygiene posters are signed by their staff members and placed where the public can see them, to further drive home the importance of hand washing. Her facility also sends out e-newsletters with hand washing updates as well as compliance progress reports for each department.
“[I’d recommend] trying the secret shopper method for a month, keep the hand sanitizers in visual locations, reward departments who have successful compliance with donuts or fruit,” Gylland says. “If the budget does not allow that, even a ‘Congratulations on Hand Hygiene Compliance’ sticker to wear with your name badge shows the healthcare system is proud of you.”
Make compliance simple and everyone’s job
Scungio says one of the best ways of getting people to follow any type of regulation is to make it easier for them to do. He points to how the placement of hand soap and sanitizer dispensers has a huge effect on if people will use them. If they aren’t in a place where it’s obvious and easy for people to access, they simply won’t use them.
“If you want people to ‘wash-in’ and ‘wash-out’ out of every patient room, you better be darn sure you have soap both outside the door and before you leave the room,” he says. “Just having it on one side of the door, in my view, doesn’t send the message that we want them to do it both times. Maybe that’s overdoing it, some people might think that’s overdoing it. But I’m a lab safety officer, I want people to comply with using personal protective equipment. But if I don’t have face shields in the department, people aren’t going to go get them if they’re not handy. You’ve got to make it easy for people to comply with the things you want them to do.”
Sentara also has put more emphasis on making all departments culpable for their hand hygiene compliance and responsible for monitoring other departments, says Scungio. Sentara has been doing departmental hand hygiene audits for the past five years, he says. While hand hygiene is still the main purview of the infection control department, the other departments are required to do hand hygiene audits of each other to make sure they stay involved in the process.
Don’t be afraid to speak out
Deborah Thompson, MD, MSPH, medical director of patient safety for Presbyterian Healthcare Services and lead author behind the AJIC study on lack of hand washing in healthcare, told HealthLeaders Media that only following hand washing guidelines two-thirds of the time is not enough to effectively prevent infection.
“Because we live in those environments all day long, and we don’t get sick ourselves, there’s a little bit of a disconnect and not a conscious one,” she said.
Leaders can tackle this problem by discussing hand hygiene with staff and encouraging people to speak up whenever they see someone not washing their hands, said Thompson. Staff should also get into the habit of saying thank you whenever someone points out that they didn’t wash their hands. It normalizes the exchange from a punitive or accusatory one to a helpful and friendly prompt.
Scungio says when it comes to hand hygiene, the biggest offenders tend to be physicians. Encouraging a culture where staff and patients feel comfortable bringing up hand hygiene compliance with physicians would have a major impact on reducing infection rates.
“There’s a lot of people—and hospitals can be guilty of this too—[who] are afraid to talk to physicians about certain issues for a number of reasons,” he says. “Though number one [reason is] we don’t want to lose our physicians; we want to keep them happy. But at the same time we need to be able to talk to them like everybody else about importance of hand hygiene.”
