The Possibility of Eliminating HAIs Using Real-Time Tracking Technology
As today marks the last day of Sepsis Awareness month, we wanted to take this opportunity to discuss how real-time location systems (RTLS) can reduce the risk of healthcare-associated infections (HAIs).
HAIs are a major, yet often preventable, concern for our nation’s healthcare system. Due to factors such as insufficient application of hygienic practices and hospital protocols, they are among the leading causes of patient disability and mortality as well as financial loss for healthcare institutions.1 Despite efforts to eliminate this problem, approximately 99,000 deaths in the U.S. still occur annually.2
In an attempt to eliminate HAIs, numerous organizations and institutions have published guidelines for improving reporting, research, staff education, accountability and surveillance systems, as well as other solutions.1 For example, the World Health Organization (WHO) developed a framework that helps healthcare workers identify moments when hand hygiene is required to prevent the transmission of pathogens during patient care.3 While educational programs have been shown to improve practices among healthcare workers, other behavior-modifying strategies, such as audits and feedback, must be implemented to affect change.1
Improving Hand Hygiene
As technology advances and process improvements are made, facilities are implementing new ways to gain greater visibility into their healthcare systems. Innovative, automatic, and cost-effective solutions like real-time location systems (RTLS) can be a valuable tool in further decreasing the burden of HAIs and the spread of other infections. By badging healthcare workers, patients, visitors, and equipment, the activity of a single hospital room can be tracked. For example, an RTLS would be able to demonstrate (1) whether or not a healthcare worker washed their hands upon entering a room, (2) the time at which they interacted with a patient or equipment and (3) if they washed their hands after the interaction before moving to the next patient room. True compliance rates are calculated by not only reporting on the number of interactions (the numerator) but also the total number of opportunities for which hand washing should have been completed (the denominator). By using this data, hospitals can audit hand hygiene processes, reduce the spread of unnecessary infections, improve patient outcomes, and lower costs.
Hospitals have begun to implement RTLS and are reporting improvements in hand hygiene compliance and the rate of HAIs. For example, RTLS technology was installed in St. Joseph Mercy Oakland, a 443-bed comprehensive community teaching hospital. The hospital reported that the system resulted in a 300 percent improvement in hand-hygiene compliance, and the HAI rate fell to zero in the pilot’s first quarter, cementing nurse buy-in to the project.4
While this use case for RTLS attempts to solve one very important aspect of disease transmission in healthcare facilities (patient-provider transmission), decreasing incidents of HAIs is a multi-component effort as infections can also spread by patient-equipment contact and even via patient-visitor contact. Tracking and managing surgical trays and medical scopes, ensuring proper air differentiation, monitoring patient interactions, and accurately distinguishing between clean and soiled equipment are all critical aspects of preventing the spread of infection in a healthcare environment.
RTLS Technology for Enhanced Infection Control
RTLS improves efficiency because of the data it can generate. Unless you have an army of people with clipboards looking at things 24 hours a day, RTLS is the only thing that can provide real-time visibility and that’s a fundamental component to getting HAI numbers down. By monitoring data and tracking patients, staff and medical equipment, facilities can identify who or what might have come in contact with an infected patient, giving them better tools to manage infection control and prevent serious outbreaks of communicable diseases. Both hospital leaders and the general public can have peace of mind knowing that immediate action can be taken to keep the public safe.
Clinical-Grade RTLS technology provides the required precision and rapid update speeds that are able to achieve room, bed, bay, and even shelf-level tracking.5 It is also resistant to the line-of-sight constraints that have plagued legacy technologies and has the added benefit of being fully waterproofed – an increasingly important requirement for asset and patient tracking deployments where infection control is a concern.
For example, with the potential for wide-spread disease and the risk of infection from surgical trays, utensils and medical scopes, it’s crucial for healthcare facilities to have the ability to track the storage, usage and cleaning lifecycles of these devices. Research has shown that the rate of HAIs after GI endoscopy is approximately 1 out of 1.8 million procedures.6 To avoid unwanted bacteria growth from organic matter or bioburden left on the device, one of the most important steps healthcare facilities must take is the reprocessing and storage of medical scopes when they aren’t in use. Accurate decontamination is a multi-step process that involves cleaning, high-level disinfection, rinsing, and drying. If one step of this process fails, there is increased risk of infection transmission from one patient to another. William Maisel, deputy director at the FDA’s Center for Devices and Radiological Health, explains, “To this day, by far the most common reason duodenscopes are not properly reprocessed, if and when they remain contaminated, is because of user error.” He also notes that meticulous adherence to existing cleaning guidelines can minimize infection risks.7
Medical Scope Lifecycle Management
Scopes must enter the initial stage of the reprocessing cycle (rinse and manual brush) within 1 hour of use. If reprocessing does not occur promptly, foreign matter has a chance to set and harden, thus increasing the chances of not being properly removed during cleaning. Utilizing active RTLS, alerts can be provided to SPW/Scope Reprocessing staff immediately after a scope is used and placed into a soiled area so that reprocessing can quickly commence – ensuring proper disinfection. A customizable second alert can be generated if the scope remains in the dirty area for more than a predefined number of minutes (as set per the facility’s protocol). Additionally, even if a scope has been reprocessed and hasn’t been used, it can only be stored for 3-12 days before needing to be reprocessed again. RTLS can help to ensure scopes approaching the 3-12 day storage limit are used vs “expire.” Automatically identifying which devices should be prioritized maximizes clinical workflow and reduces unnecessary and destructive reprocessing. When used in conjunction with RTLS technology, asset tags that are capable of withstanding high-pressure washing and harsh disinfection chemicals enable healthcare facilities to easily and safely monitor their mobile medical devices.
Overall, Clinical-Grade RTLS has been shown to provide medical centers with the ability to mitigate the spread of HAIs and other infections – saving lives, decreasing overall cost, and increasing reimbursements.
