Wiping out pathogens with multi-area cleaning

Aug. 21, 2020

Infections and deaths from COVID-19, caused by the virus SARS-CoV-2, continue to soar throughout our communities. Many people stay home, limit contact with others and hope to not get infected. But what if an emergency health situation arises and a hospital visit is needed?

For vulnerable populations, such as senior citizens and individuals with serious, underlying or immune-compromised health conditions, delaying or forgoing emergency care can cause harmful complications, or even deaths. That can be equally dangerous for people who are experiencing heart attacks, strokes or other life-threatening events.

“A recent poll by the American College of Emergency Physicians found that 29 percent of adults have avoided medical care because they are concerned about contracting the virus,” shared Tom Mihaljevic, M.D., Cleveland Clinic CEO and President, in his online message to patients. “Hospitals nationwide have seen a 38 percent decline in the number of patients presenting with heart attacks across the United States. This is extremely concerning, especially for patients with heart disease and cancer, who require early screening, constant surveillance and treatment. If you have a medical emergency, do not hesitate to call 911 or go to your nearest emergency department.”1

Ensuring safe spaces

The guidance is clear, however, from hospitals, healthcare facilities and medical associations, that it is currently safe for patients to go into medical settings for care. These facilities also are restarting elective surgeries and treatment, but with an eye of caution.

The American College of Surgeons (ACS) guidance states, “Although this document, ‘Local Resumption of Elective Surgery Guidance,’ provides principles to help local facilities safely resume procedures after COVID-19 peaks locally, there is still much work to be done. While COVID-19 cases may have peaked in certain areas, the virus is still circulating and there is much we don’t know about the etiology and progression of the disease.”2

To help keep patients, loved ones and staff safe, Cleveland Clinic and other facilities nationwide are following federal healthcare guidelines and putting protective measures in place.

“Cleveland Clinic has been limiting visitors, delaying some surgeries, providing proper personal protective equipment for caregivers, disinfecting surfaces, practicing physical distancing and screening patients and caregivers for COVID-19 symptoms including taking people’s temperatures at building entrances,” Dr. Mihaljevic continued in his message. “As we resume clinical services, we will continue to ensure that our patient waiting areas are reconfigured for safety.”

Other considerations for visitors to healthcare settings, according to guidance from the Centers for Disease Control and Prevention (CDC), include, “Visitors should only visit the patient they are caring for and should not go to other locations in the facility. Facilities should provide education on appropriate PPE use, hand hygiene, limiting surfaces touched, social distancing, and movement within the facility. Facilities should consider the need to conduct active screening for visitors with potential exposure to SARS-CoV-2 due to a breach in infection prevention and control (IPC) protocol.”3

Concentrated cleaning and infection prevention

Hospitals and other highly susceptible settings for viral, disease or healthcare-associated infections maintain an increased focus on cleaning, disinfection and infection prevention during COVID-19. This may require adjusting supplies and equipment, conducting training for environmental services (EVS) staff, performing a variety of techniques, conducting frequent routines and covering many areas for adequate decontamination. 

“COVID-19 heightened the awareness of the importance of cleaning and disinfection practices in hospitals and healthcare facilities,” indicated Doe Kley, BS, RN, CIC, MPH, CIC, T-CHEST, Senior Infection Preventionist, Clorox Healthcare. “The EVS teams that support medical facilities across the country have adapted their practices to help prevent the spread of SARS-CoV-2, especially increased frequency of high-traffic and high-touch equipment and environmental surfaces. And of course, they are ensuring they are using products effective against this virus (e.g., EPA List N). These teams are investing in more disinfection tools that have EPA-approved emerging viral pathogens claims against SARS-CoV-2. Examples include trusted solutions, like bleach, and new technologies, such as electrostatic sprayers.”

Disinfecting spaces

There has been a longtime commitment of cleaning along with a need for additional support to safely disinfect healthcare environments, emphasizes Sarah Simmons, DrPH CIC FAPIC, Senior Director of Science, Xenex Disinfection Services.

“Hospital Infection Preventionists and EVS directors have been pleading for years for resources and new technology to enhance environmental cleanliness and battle deadly pathogens in their facilities,” Simmons said. “Nearly 300 people die every day in the U.S. from an infection they contracted during their hospital stay – and that was before COVID-19.”

“We’ve seen a lot of innovation from hospitals and healthcare facilities as a result of COVID-19,” she continued. “Hospitals moved LightStrike disinfection robots from their ORs to the Emergency Departments, so they could immediately disinfect rooms and areas where suspect patients were being treated. We were in a Texas hospital recently when they learned someone in their Accounting department tested positive for COVID-19. They immediately sent a LightStrike robot from the ER to Accounting to rapidly disinfect the entire area and conference room. The LightStrike robots have been proven effective against SARS-CoV-2, and our pulsed xenon UV light achieved a 99.99 percent level of disinfection in two minutes.”

Patrick J. Piper, President and CEO, Far UV Technologies, Inc., sees hospitals, medical and dental clinics and other healthcare facilities reassessing and improving processes and tools to aid in patient and staff protection. 

“While previous cleaning and disinfection approaches targeting the containment or reduction of hospital-acquired infections were often considered good enough before the pandemic, the significant safety and financial risks associated with COVID-19 spreading within their facilities has heightened the urgency to come up with more autonomous, continuous solutions and has many providers turning to newer innovative disinfection technologies,” Piper explained. “The benefits of Krypton disinfection lighting to safely and effectively eradicate disease causing pathogens in occupied spaces has been known for some time. No one wants to catch this virus.  We are a simple, ‘set it and forget it,’ safe, autonomous and continuous solution, ultimately providing much greater degrees of viral load reduction at lower cost than other approaches.”

Widespread cleaning in many areas to decontaminate hard surfaces is an extra focus and an additional layer of protection for facilities, stresses Steven Baiocchi, Chief Operating Officer, Steriliz, LLC.

“Hospitals and healthcare facilities are paying more attention to the important work their cleaning staff performs and have a heightened sense of the importance of disinfecting additional areas throughout their facilities, not just contact precaution rooms,” Baiocchi expressed. “Manual cleaning is still subject to human error, so the use of no-touch disinfection technology, such as UVC, has become an essential addition to a bundled process. The RD UVC system kills pathogens with a measured delivered UVC dose that provides comprehensive coverage and proof-of-compliance. Single-stranded RNA viruses, such as SARS-CoV-2, can be inactivated by UVGI exposure, which is also being applied to help kill the COVID-19 virus on surfaces, in the air and in other areas that can act as a vector to transmit the disease.”
Peter Veloz, CEO, UltraViolet Devices, Inc. (UVDI), calls out the benefit of automated disinfecting devices for the safety of healthcare workers and the speed of room turnover.

“Their (healthcare front line workers) understanding of unseen risks in the environment prior to and during the pandemic has driven widespread use of enhanced environmental hygiene protocols and solutions like our UVDI-360 Room Sanitizer, which is now used in 25 countries,” Veloz said. “In addition, emerging research about the virus’ persistence and transmission on surfaces has increased interest in hands-free disinfecting practices, which can limit person-to-person and person-to-surface exposure. The UVDI-360 Room Sanitizer is proven in independent lab testing to inactivate over 35 pathogens, including coronavirus. UVDI-360 can disinfect a typical patient room in 10 minutes and a bathroom in five minutes, enabling rapid room turnover while not disrupting workflow. It can be easily activated remotely via an app or directly from the device.”

Disinfection systems can extend into long-term care settings and emergency vehicles for added protection for residents, staff and first responders, points out David St. Clair, Chairman and CFO, Halosil International.

“As COVID-19 continues to spread, healthcare facilities are reevaluating their strategy for whole room disinfection, particularly in areas that historically were not a primary area of focus,” St. Clair explained. “For instance, hospitals are increasingly assessing tactics for disinfecting emergency transport vehicles, which come into contact with a high volume of staff and patients. In long-term care facilities, practices for disinfecting shared spaces, such as dining halls and recreation rooms, and individual spaces, such as residents’ rooms, are being examined to ensure the highest efficacy and most uniform disinfectant delivery are achieved. As the first dry-fogging solution approved to kill C. difficile spores, the Halo Disinfection System has a proven track record eliminating challenging pathogen types. Our HaloMist (EPA Reg. No. 84526-6) disinfectant has been added to the EPA’s List N.”

Sanitizing surfaces

Healthcare supply and equipment shortages have plagued hospitals and facilities amidst the pandemic, which has led to greater resourcefulness and flexibility with cleaning and disinfection products and use, explains Ben Oberle, Healthcare & Education Marketing Manager at 3M Commercial Solutions Division.

“They (healthcare facilities) are having to adapt to industry-wide product shortages on the products they’ve always relied on to get their jobs done well,” Oberle stated. There is a heightened focus on ensuring proper usage of products and promoting transparency to patients and staff on cleaning and maintenance practices. Our disinfectant chemicals are being paired with mops and tools to clean and disinfect throughout healthcare facilities.”

Marc-Oliver Wright, MT(ASCP), MS, CIC, FAPIC, Professional Disposables International, Inc. (PDI), emphasizes the concentration on disinfecting many area and items, changing cleaning products and providing staff education.

Under appreciated areas/surfaces, such as waiting areas or personal electronic devices, are all getting a little more scrutiny when it comes to cleaning and disinfection,” Wright said. “Supplemental disinfection technologies have really had a moment during COVID-19. Facilities have had to be adaptive to new products during supply chain disruptions. This includes training and educating staff about a new disinfectant product, often on short notice. Having eight PDI Healthcare and Sani Professional disinfectant lines on the EPA’s List N meant that the vast majority of our existing customers were already accustomed to using a product deemed to be effective against this virus. Additionally, the newly established partnership between PDI and Tru-D Smart UVC facilitated our ability to serve our customers through the challenges posed by this crisis.”

Leveraging the right roles, products and work routines can help raise the speed and effectiveness of cleaning and disinfection, notes Larinda Becker, Healthcare Marketing, Diversey, Inc.

“There are many considerations to ensure optimization including clearly defined roles and responsibilities, the right tools to do the job to ensure compliance and efficiency, and validation programs to improve processes and focus on ongoing training,” Becker indicated. “Diversey’s Oxivir disinfectant cleaners are fast and effective against pathogens of concern. In addition, the MoonBeam3 disinfection technology has been implemented across many facilities globally, adding UV-C disinfection for added assurance. MoonBeam3 is highly effective with fast cycle times, streamlining workflows. It is easy to use, offers safety features and is portable and easy to store and transport.” 

Katherine Velez, Ph.D., Senior Scientist, Clorox Healthcare, agrees that using the right products in quicker time can enhance cleaning and disinfection of all surfaces across healthcare and other industries.

“Electrostatic spraying is a well-established technology with a history of use in other areas, including agriculture, automotive and tanning industries,” Dr. Velez stated. It has only recently been applied to surface disinfection. This technology is a new way to apply cleaners, sanitizers and disinfectants to surfaces, in less time than it would take to apply the same products manually. The Clorox Total 360 electrostatic sprayer is designed to apply disinfectants and sanitizers on all sides of hard-to-clean surfaces and equipment, such as portable equipment and wheelchairs. The system uses patented technology to charge the disinfectant solution, which causes disinfectant droplets to stick to surfaces and consistently coat all surfaces for comprehensive coverage.”

Implementing an environment-friendly disinfection system has resulted in killing pathogens quickly, preparing rooms faster and enhancing patient and staff safety and satisfaction, shares Liz Shelton, Administrative Director, Hospital Operations, CHRISTUS Trinity Mother Frances Health System.

“We had R-Water’s disinfecting system as a pilot initially in 2018, to help speed up the disinfection process for rooms after treating patients for C. diff,” Shelton said. “We also wanted to decrease our turn-around time in our Operating Rooms. This system helps us achieve our goal to ensure we are keeping our nurses and patients safe while killing all harmful organisms.”

“We received our second machine in mid- to late-March, when COVID was first impacting Texas,” she continued. “These two systems helped us ensure an adequate supply of disinfectant for our ORs, hospital and clinics. Because the system produces disinfectant on-site, we’re able to reuse supplies and reduce waste. Plus, because it (R-Water’s disinfecting solution) is not toxic, it can be disposed of more easily. We just deployed R-Water in our clinics. The nurses love it and feel safe. We significantly decreased our cleaning times by using R-Water, and that allows us to spend more time treating patients.”

Protection of mattresses, where patients spend most of their time, requires a specialized barrier that can help shield patients from infection risk, expresses Bruce Rippe, CEO, Trinity Guardion, LLC.

“Some hospitals are using more rigorous techniques particularly after COVID-19 discharges, such as more frequent cleaning of patient rooms and use of stronger disinfectants during terminal cleaning,” Rippe noted. “Stronger disinfectants can damage mattress skins and mattress cores – and damaged mattresses increase the infection risk for patients. That’s why ECRI sounded the alarm on mattress contamination, citing it as a top health hazard in 2018 and 2019.”

“Trinity’s product is designed specifically for the healthcare mattresses of today, which have changed from vinyl (hard /non-porous surface) to polyurethane (soft /porous surface),” he added. “Our launderable bed barriers meet and surpass the required disinfection guidelines. We leverage a high-heat laundry process. As a result, beds and mattresses are cleaner when compared to more traditional disinfection methods – and the risk of cross-contamination is eliminated.”
