The goal of any Environmental Services Department within a healthcare facility should be to prevent the spread of infectious agents among patients and healthcare workers by meticulous cleaning and appropriate disinfection of environmental surfaces. To reach this goal, the EVS department will need to have a comprehensive training program, the objective of which should be to provide department staff with the information they need to accomplish their jobs safely. The training program should be a part of the big picture of “How to Protect Yourself.” At a minimum the training program should include the following:

1. Identification of occupational risks and hazards associated with handling infectious waste.
2. Sharps safety.
3. Blood borne pathogens.
4. Infection control training – (a) Microbiology and (b) Transmission.
5. Hand hygiene.
6. Personal Protective Equipment (PPE) including donning and doffing.
7. MSDS and hazards associated with using chemicals (cleaning agents, disinfectants, etc.)
8. Product usage training including proper cleaning and disinfection techniques.

The benefit behind breaking the training into sections is two-fold. First, it allows the person responsible for training to involve other departments such as Infection Control or Occupational Health & Safety where specific knowledge and expertise can be called upon. Second, by segmenting the areas into shorter pieces the trainee is not overwhelmed. The individual sections also allow for developing unique methods of delivery. Education should be tailored to the size, topic and needs of the group. Not all programs must be instructor-led in classroom setting. They can also consist of CD programs and/or video-based programs or a series of self-study modules. For example, the product usage training may be better suited to a traditional classroom setting where employees can observe someone performing the task while other sections such as Blood Borne Pathogens can use video-based training. Switching up the method of delivery helps keep the trainee engaged.

A basic understanding of these eight topics doesn’t require a stethoscope or coke-bottle glasses, or even the ability to squint. It takes knowledge, imagination and responsibility. Knowledge… to know basic microbiology, where pathogenic microbes are found, and how they cause disease; to know how cleaning and disinfectant products should be used; to know how to be protected from exposure to blood borne pathogens and sharps injuries; about the proper use of PPE. Imagination… to be able to actually picture the microbes all around us. Responsibility… to take reasonable action to prevent disease.

One person dies every six minutes from hospital-acquired infection. It’s tragic that this is allowed to continue and that an Environmental Services department can be allowed to operate without ongoing, targeted and evolving education.

Time spent properly training staff is an investment that pays dividends for a long time. Training should be a constant process, not just something you do for new employees or to meet the annual requirement. Whenever new products, equipment or procedures are introduced into your department, all staff should be trained on their safe and proper use. Research has shown that adults learn differently than children do, they generally learn more and retain more if they are involved in the training process. Adults learn best by doing, not by listening to lectures or by viewing videos. Lectures and videos have a place in the training process, but trainee involvement needs to be included.

Feel free to share your thoughts and comments.

The process of physical cleaning of environmental surfaces using detergent (soap), water, and friction is the critical step required prior to surface disinfection. The combination of the cleaning and disinfection processes is designed to remove and kill vegetative microorganisms on surfaces. Disinfection will not be effective in the presence of dirt, blood, or other bio burden. The  goal of the cleaning step is to remove bio burden and with it, the majority of pathogens. Disinfection is designed to be a synergistic and somewhat redundant step to ensure comprehensive removal/kill of pathogens on surfaces.

The CDC’s Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008, states that, “noncritical surfaces (e.g., dialysis bed or chair, countertops, external surfaces of dialysis machines) should be disinfected with an EPA-registered disinfectant unless the item is visibly contaminated with blood. In that case, an EPA registered tuberculocidal agent with specific label claims for HBV and HIV should be used.”1 the commonly used disinfectant for blood contaminated environmental surfaces is a 1:100 dilution of bleach (500–600 parts per million [ppm] free chlorine).

The environmental surfaces in HD settings at highest risk of transmitting germs are described using different terms. From the perspective of the patient, the term “patient zone” is used to refer to the surfaces which the patient can touch, or can touch the patient, including the chair, armrests, bedside table top/counter, and drawer/cupboard handles. From the HCW or dialysis staff perspective, the term “high touch surfaces” is used to describe surfaces which are frequently touched by HCWs. These include the same surfaces in the patient zone in addition to others such as the exterior surfaces of the HD machine, computer screens, and keyboards. Cleaning and disinfection of these surfaces (patient zone/high touch surfaces) should be performed between all patient treatments, no matter what the patient diagnosis is, in order to prevent spread of environmentally transmitted pathogens including MDROs (e.g., MRSA, VRE, C. difficile) and bloodborne pathogens (e.g., HBV, HCV). Of note, microorganisms can live for varying periods of time in the environment. MRSA has been documented as viable at 38 weeks on external sterile packaging and VRE at 6 months on a wheelchair. HBV can survive for 7 days in dried blood.

There are certain products and principles which are recommended in order to optimize environmental cleaning in healthcare settings, including HD facilities. These include the following tasks which are typically performed by the dialysis nurse or technician.

• Store cleaner/disinfectant separately from skin antiseptics/patient supplies (separate shelves and below patient supplies to avoid potential contamination).

• Perform hand hygiene before and after cleaning the patient station.

• Don gloves when using cleaner/disinfectants.

• Use one set of cleaning cloths or disposable germicidal wipes for each patient station.

• Use microfiber cloths and mops if possible (more effective cleaning products than regular cotton cleaning cloths).

• Clean all frequently touched or “high touch” surfaces in the “patient zone” between patient treatments (chair, armrests, counters, drawer/cupboard handles, exterior surface of the HD machine)—please note that some of these high touch surfaces may be right outside the patient zone (e.g., computer stations), and must also be cleaned between patient treatments.

• Clean the top of an object first and work down to avoid soiling surfaces just cleaned.

• If using cleaning cloths instead of disposable germicidal wipes:

• When using a disinfectant cleaner, wet the surface, use friction to clean, and allow to air dry.

• Fold the cleaning cloth in a series of squares to provide a number of potential cleaning surfaces. A wadded cloth does not clean efficiently.

• Replace cloth as needed. More than one cloth may be required for a patient station.

• Never use the same cleaning cloth for more than one patient unit.

• Never re-dip used cloth into clean disinfectant solution.

Additional cleaning functions, typically performed by housekeeping staff in HD facilities, should include:

• At the end of the day:

• Wet mop the floor

• Clean patient/staff bathrooms and restock paper products/hand hygiene supplies

• Check and refill all hand hygiene product dispensers in nursing stations and at patient stations (soap, paper towels, lotion, alcohol-based hand sanitizer)

• On a routine basis, walls and high dusting should be performed.

Multi Drug Resistant Organisms Cleaning and Disinfection

Many healthcare workers believe the environment of patients with MDROs require special cleaning. Healthcare workers in HD facilities should clean the environment of the MDRO patient as they would for any patient, as many more patients than are known are colonized/infected with an MDRO. Cleaning involves the use of friction on environmental surfaces to physically remove the soil and germs. The wet contact time of the germicide on the surface helps kill or inactivate any remaining microorganisms. The exception is C. difficile, which requires removal by friction and is not inactivated by any surface disinfectant except bleach.

Here is the two step cleaning training video I participated in as a technical consultant. We filmed this video at the new beautiful Mercy Medical Center in Merced California. The purpose of this video is to help Environmental Services staff save lives. We believe it is not enough to simply clean with a disinfectant anymore. Microfiber, two step cleaning, and a move away from “quat” based cleaners is long overdue.

In the great work presented in Options for Evaluating Environmental Cleaning, December 2010 by Alice Guh, MD, MPH and Philip Carling, MD, objective monitoring of environmental surfaces was studied and presented as a necessary component of training. In view of the evidence that transmission of many healthcare acquired pathogens (HAPs) is related to contamination of near-patient surfaces and equipment, all hospitals are encouraged to develop programs to optimize the thoroughness of high touch surface cleaning as part of terminal room cleaning at the time of discharge or transfer of patients. A two level approach to this is presented and quite well discussed.

For now please draw your attention to the 8 locations above. The importance of targeted cleaning to these surfaces must be taught to your staff and reinforced on a regular basis. While many of our staff have an excellent understanding of the basic policies and procedures involved in terminal room cleaning, most will benefit from focused educational interventions related to our evolving understanding of the role of the environment in healthcare-associated pathogen (HAP) transmission. Specific targeted cleaning will not only reduce HAI’s it will greatly increase the awareness level of your staff.

As part of the proposed changes to healthcare, reimbursement for hospital care and post-acute care will be bundled; patient readmission’s will be at a lower rate in some cases; hospital reimbursement and performance will be directly linked; and physician self-referral will be more closely regulated. Out of those four important items, environmental services has a direct impact on two—readmission rates and performance-based reimbursements. A sufficiently staffed environmental services department plays a major role in minimizing patient readmission’s. The proliferation of microorganisms affecting our communities and the patient population demands a properly cleaned and disinfected care environment. It is my belief that investing in the environmental services department and assuring proper funding, staffing, training, and consistent cleaning procedures and protocols will have a positive impact on lowering the infection rates, lowering the rate of “never” events like patient falls and improving patient satisfaction rates. Each of these examples provides a direct link between our departments and performance-based reimbursements.

So what does this all mean to the environmental services department? This is an opportunity to position the department as the front-line quality assurance and infection control team able to facilitate cost containment for the health care facility and ensure a proper setting for care delivery throughout the continuum of care. Speak up and make sure your senior leaders know the value you and the departmental staff bring to the health care facility. Make the business case for what you do and the big-picture impact on finances, patient readmission and performance-based reimbursement.

What is Clostridium difficile?

Clostridium difficile is a spore-forming, gram-positive anaerobic bacillus that produces two exotoxins: toxin A and toxin B. It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.

Clostridium difficile is a bacterium that may develop due to the prolonged use of antibiotics during healthcare treatment. Clostridium difficile infections cause diarrhea and more serious intestinal conditions such as colitis. The CDC provides guidelines and tools to the healthcare community to help end clostridium difficile infections and resources to help the public understand these infections and take measures to safeguard their own health when possible.

C. difficile is an anaerobic, gram-positive bacterium. Normally fastidious in its vegetative state, it is capable of sporulating when environmental conditions no longer support its continued growth. The capacity to form spores enables the organism to persist in the environment (e.g., in soil and on dry surfaces) for extended periods of time. Environmental contamination by this microorganism is well known, especially in places where fecal contamination may occur. The environment (especially housekeeping surfaces) rarely serves as a direct source of infection for patients. However, direct exposure to contaminated patient-care items (e.g., rectal thermometers) and high-touch surfaces in patients’ bathrooms (e.g., light switches) have been implicated as sources of infection.

How is Clostridium difficile transmitted?

Clostridium difficile is shed in feces. Any surface, device, or material (e.g., commodes, bathing tubs, and electronic rectal thermometers) that becomes contaminated with feces may serve as a reservoir for the Clostridium difficile spores. Clostridium difficile spores are transferred to patients mainly via the hands of healthcare personnel who have touched a contaminated surface or item.

Transfer of the pathogen to the patient via the hands of health-care workers is thought to be the most likely mechanism of exposure. Standard isolation techniques intended to minimize enteric contamination of patients, health-care–workers’ hands, patient-care items, and environmental surfaces have been published. Hand washing remains the most effective means of reducing hand contamination. Proper use of gloves is an ancillary measure that helps to further minimize transfer of these pathogens from one surface to another.

What can I use to clean and disinfect surfaces and devices to help control Clostridium difficile?

Surfaces should be kept clean, and body substance spills should be managed promptly as outlined in CDC’s "Guidelines for Environmental Infection Control in Health-Care Facilities." [PDF 1.4 MB] Routine cleaning should be performed prior to disinfection. EPA-registered disinfectants with a sporicidal claim have been used with success for environmental surface disinfection in those patient-care areas where surveillance and epidemiology indicate ongoing transmission of Clostridium difficile. It is important to distinguish the need for a disinfectant with a sporicidal claim. Currently only specific bleach containing products have this registration. Bleach harms surfaces and is hazardous to the user. Normally, HAI’s can often be controlled with good cleaning practices and a non bleach disinfectant.

The recommended approach to environmental infection control with respect to C. difficile is meticulous cleaning followed by disinfection using hypochlorite-based germicides as appropriate. I recommend using microfiber towels and an accelerated hydrogen peroxide based disinfectant. There are now a few products with a C.difficile claim. One I have tried is Dispatch wipes. I found the odor to be acceptable for most of my staff but the film left after using is a significant and required a second cleaning to remove it for an acceptable appearance.

Here I continue to list cleaning standards. We use these as a guide to understanding our responsibilities in general cleaning. This is not meant to be a complete list, rather a broad overview. Enjoy your reading:

I had a request for basic cleaning principles for a doctor’s office. Here is a list for any healthcare facility, and for your home as well.

• Scrubbing is the best way to physically remove dirt, debris and microorganisms.
• Cleaning is required prior to any disinfection process because dirt and debris will decrease the effectiveness of disinfectants.
• Cleaning products should be selected on the basis of their use, efficacy, safety and cost.
• Cleaning should always progress from the least soiled areas to the most soiled areas and from high to low areas, so the the dirtiest areas and debris that falls will be cleaned up last.
• Dry sweeping, mopping and dusting should be avoided to prevent dust and microorganisms from getting into the air and landing on clean surfaces.
• Mixing and dilution instructions must be followed. Too much or too little will reduce the effectiveness of cleaners and disinfectants.
• Cleaning methods and written cleaning schedules (work routines) should be based on the type of surface, amount and type of soil present and the purpose of the area.
• Routine cleaning is necessary to maintain a standard of cleanliness. Work schedules and procedures should be consistent and posted.

There you go, general principles for cleaning hospitals, clinics and other healthcare facilities summarized.

Highlighting common scenarios from hand hygiene and glove use to properly cleaning patient rooms, this video will illustrate the type of precautions that housekeeping staff should take to protect themselves and patients from germs and infections that could make them sick.

I hope there is some relief in the activity at your institution now that we have made it through another heavy viral season. Not that there really is a slow season in health care anymore, just a less busy one. So, welcome to the less busy season, when there is time to think and plan.

Environmental services departments are pivotal in the “flow” process, but it must be balanced with proper infection control practices. The challenge is timely, thorough communication—getting and giving good information.

Let’s imagine the emergency room waiting area is filled to capacity and census is at 99 percent. The health care institution has a patient throughput initiative and, hopefully, all of you have been involved in this initiative.

Here is the scenario:

The emergency room has just informed Patient A that he will be admitted. Bed management then scurries to see where the patient can be placed. For purposes of this scenario, we will assume Patient A is a cardiac patient and will need to be admitted into the cardiac intensive care unit, which is currently full. This means the patient shuffle will now occur.

This pending admittance is happening after 7 p.m., when staffing is at a lower level. The most stable patient, Patient S in the cardiac intensive care unit, will move to the step-down unit. But Patient O, who is currently in the step-down unit, needs to be relocated since there is now no need for monitoring this patient, but he is still not ready for discharge. We will now have to move multiple patients to get emergency room Patient A into a necessary room, but the only data that will be looked at is the time it takes to get Patient A to his room, although this is not the only process that is occurring.

The race is on to get Patient A into an intensive care unit room within a certain time frame. Patient S, who is in an intensive care unit room, has to move to the step-down unit room occupied by Patient C. Patient C is stable enough to move to Patient H’s room, which was discharged earlier in the day during the shift change.

This means either there was a lack of communication or miscommunication both from human beings and/or from the “fail-safe” electronic system to notify the incoming environmental services shift of the discharge. The room now resides in “neitherland”; hopefully, it will be discovered and cleaning completed within the required amount of time of the patient flow initiative. If not, we just encountered our first “dam” in the flow.

The current status for environmental services is one critical patient in the emergency room, two patients needing relocating, four rooms counting the ER exam room needing to be cleaned, with the emergency room waiting area overflowing and the health care institution on the verge of going into divert. Contact time to properly disinfect surfaces is 10 minutes, and two of the three rooms are in the same cleaning zone of one person. Patient C needs to go into Patient H’s room, which is the empty discharge room that is lost in the communication process. Patient A, who will move when Patient O moves, can go into Patient S’s room. What does all this mean for the hospital’s environmental services department?

Well if you played along with my little word game, the answer is “chaos”! Most hospitals spend from November to April in this type of scenario. Though the patient flow initiative may not have been accomplished, patients are treated in a timely, effective and safe manner with positive outcomes.

Now, when things are calmer, evaluate your turnaround times, your communication methods and your systems and start to develop process improvement initiatives. Use this time to document, evaluate your data and present this information to your administrator with improvement suggestions. This will assist you and your staff to develop, acquire or change initiatives that will lessen the burden next viral season.

On the road to excellence!
