perspectives By Matthew Hardwick, PhD Education and Training of Frontline Infection Preventionists O ne of the most fundamental operations in any medical facility is cleaning. However, cleaning hospitals has followed the same basic principles as cleaning hotel rooms — clean visible soil. While there are cleaning protocols in place at nearly all medical facilities, the predominant feature of these protocols is routine cleaning with a focus on visible soil. It should surprise no one that pathogens do not always reside in visible soil. Indeed, many of the fluids and semi-solids that transmit pathogens are not readily visible to the naked eye (think sputum or fingerprint oils). Nevertheless, many cleaning protocols do not take invisible soil into account during both routine and specialized cleaning protocols. Everyone in healthcare is responsible for this lack of awareness. While environmental services (EVS) personnel, nurses and technicians are primarily responsible for keeping medical facilities and equipment clean, they are only as good as they are trained to be. From the CDC to AHE to APIC, all agree that EVS personnel require extensive training to play their pivotal role in keeping healthcare environments free of pathogens. Indeed, each has dedicated significant resources to developing training programs for EVS workers. AHE has a suite of training pro- grams aimed at frontline EVS workers, ranging from surgical suite cleaning to EVS management and leadership. Through funding from the CDC, APIC has developed training modules that run the gamut of cleaning from the basic principles, per- sonal protective equipment, chemical safety, and techniques for cleaning and disinfection. In addition to these resources, vendors have developed their own extensive training for EVS workers. Such training is perhaps more individualized and often encompasses multiple days for training sessions and accompanied by annual refreshers for each worker. Key tools require training: • Fluorescent markers – This tool was developed in order to provide “before” and “after” feedback for EVS workers. In short, an invisible fluorescent gel is applied to pre-deter- mined surfaces prior to EVS cleaning. Following cleaning, a manager uses a black light to determine if the gel has been removed from all the spots. In this way, the manager can determine adherence to cleaning protocols. It should be noted, however, that this method does not determine the efficacy of removing pathogens from environment. • Adenosine triphosphate (ATP) swabs – One way to determine if a surface is free of pathogens is to detect organic ATP (derived from biological organisms like bacte- ria, fungi and human cells) left on surfaces. ATP detection is performed only following cleaning, reducing the time needed for monitoring. In theory, this method will not only determine an EVS workers adherence to established cleaning protocols, it will also evaluate the protocol for pathogen 8 removal. There is one big problem with this method, however. First, we do not know the half-life of biologically derived ATP, meaning that cells maybe dead (killed by auxiliary techniques such as UV and vapor) and still leave active ATP behind. In our laboratory, we have detected ATP signals in the absence of viable bacterial loads, more than 48 hours after exposure to UV light. The development of fluorescent marker and ATP swab methodologies are a boon to the education and monitoring of EVS workers. However, given the limitations of both the current cleaning methodologies and these monitoring devices, we still have a long way to go before we have adequate tools to empower EVS workers. While EVS personnel receive considerable training, nurses and technicians may only receive cursory training, if any at all, on how to clean medical equipment and how to use disinfectants. APIC’s training does include sections for healthcare professionals including a section on “roles and responsibilities” geared toward who cleans what in health- care environments. Despite APIC’s efforts, there is clearly a gap in training for nurses and technicians. This education and training gap is critical, since these individuals are largely responsible for cleaning critical patient-care equipment such as blood pressure monitors and dialysis machines. Without understanding which disinfectant to use and the appropriate dwell times, as well as how to use wipers in order to reduce cross-contamination, we cannot begin to hope that healthcare surfaces will be cleaned properly. In last month’s Healthcare Hygiene magazine, Linda Ly- bert and Caroline Etland described a comprehensive literature review commissioned by the Healthcare Surfaces Institute. As a part of this review, studies on current healthcare training and education were examined. Despite the availability of numerous training programs and studies to show that only 48 percent of healthcare surfaces are cleaned appropriately, no research studies were found to determine if these programs are effective. Rather, only a handful of research studies were focused on monitoring cleaning practices. This lack of scientific research into the effectiveness of EVS training is surprising and, frankly, appalling. Given the rapidly evolving world of infection prevention, it is critical that all healthcare professionals – EVS workers, nurses, technicians – receive the education and training they need to fill their roles as frontline infection preventionists.
