Two Reasons Following IFUs is a Necessity

Reusable medical devices can present a host of opportunities for hospital acquired infections (HAIs) or surgical site infections (SSIs). One critical area in which the risk for HAIs and SSIs must be reduced involves following manufacturers’ instructions for use (IFU) during the decontamination and sterilization processes.

 

The complexity of instruments that central sterile processing departments are charged with cleaning, is changing and evolving. From laparoscopic instruments with small hinges and lumens to rigid and flexible scopes with delicate channels, these instruments require specific steps to ensure that they are properly cleaned and sterilized. Without doing so, the risk to patient and staff safety increases exponentially.

 

IFUs are “written recommendations provided by the manufacturer that provide instructions for operation and safe and effective use of its device. …The device manufacturer is responsible for ensuring that the device can be effectively cleaned and sterilized with the means and methods available in health care facilities. Sterilization validation of a device requires microbiological, engineering, toxicological, and sometimes clinical evaluations of the device, which are beyond the abilities of most health care facilities. To ensure patient safety, a reusable device needs to be capable of being thoroughly cleaned and sterilized. The device labeling describes specific methods of cleaning and sterilization that have been validated by the manufacturer.”[1]

 

Throughout the decontamination and sterilization process, ANSI/AAMI ST79: 2017 Comprehensive guide to steam sterilization and sterility assurance in health care facilities, requires that departments ensure effective decontamination and sterilization by following the device manufacturer’s written IFU.  To do so, IFUs should be easily accessible, reviewable, and followed. If no IFU exists for a device, instrument, equipment, or solution, the manufacturer should be contacted and a documented method of cleaning should be provided.

 

IFUs address several areas of concern. Many instruments or devices have numerous parts that must be disassembled for proper reprocessing. Understanding how those intricate parts work, the design elements, and possibly overlooked areas for cleaning, are essential to ensuring that a device is sterilized. Cleaning solution IFUs are another area that need to be taken into consideration. Proper dilution, concentration, temperature and contact time are vital for ensuring proper decontamination and sterilization. Additionally, some instruments and devices cannot be treated with specific solutions. Following manufacturers’ IFU will help prevent unnecessary damage the instrument. IFUs for reprocessing equipment are equally important. Without proper knowledge of the tools used to reprocess the instruments, effective reprocessing cannot be achieved.

 

While instrument damage and inventory protection is important, there are only two reasons why manufacturers’ IFU must be made available and followed:

 

  1. Patients: “IFU compliance is a must because we impact patients’ lives when the instruments used are contaminated. Patients come into the surgical suite with a medical problem that can be made better with surgery; the instruments used on that case must be processed following the IFU all in the name of patient safety.”[2]
  2. Staff: Your staff is your most valuable asset. Simply put, without central sterile processing staff, reusable medical devices would not get reprocessed. The risk of injury from equipment and instruments as well as exposure to harmful chemicals can be reduced by following IFUs. Departments cannot afford to lose their most valuable assets to often avoidable injuries.

 

Many tools exist for helping central sterile processing departments to ensure IFUs are followed. From digital databases that can be accessed through a computer at a workstation, to available hard copies of IFUs, departments must make sure IFUs are accessible to all staff. Training and in-servicing help to ensure that IFUs are followed, patient safety is not compromised, and that staff are able to safely perform their tasks.

Accelerate the breakdown of bioburden on surgical instruments and devices with enzymatic products

Improve patient safety, reduce HAIs and enhance effectiveness of cleaning

Central sterile and endoscopy reprocessing tools continue to evolve to help improve patient safety outcomes. However, even with improvements, surgical site infections (SSIs) are the third most reported healthcare acquired infection (HAI) and can threaten a patient’s life, increase hospital stays, and increase healthcare costs.1

 

Removing bioburden from medical devices and instruments is essential to the safety of the next patient who will be exposed to the sterilized instrument. Even though an instrument may be considered clean and sterile, dried on bioburden in instrument lumens and channels are a culprit in causing many SSIs.

 

Bioburden is the term used to describe the whole population of viable microorganisms that inhabit a non-sterile surface or device.2 When utilizing reusable surgical instruments and devices, blood, fats, tissues, and other forms of bioburden, can quickly coagulate on instrument joints, hinges, grooves, lumens and channels. As the coagulated soil dries, it cements itself to microscopic irregularities on the surface of instruments.3 This renders the instrument or device difficult to clean, requiring more time for brushing and scrubbing to achieve cleaning compliance.

 

Preventing the hardening and enhancing the breakdown of bioburden on instruments and devices and can easily be achieved with one simple step: enzymatic products.

 

Enzymatic cleaners are biodegradable, non-toxic cleaning agent used to break down soil on instruments. By applying an enzymatic cleaner on the instrument immediately after use, the cleaner helps keep the instrument moist while also working to loosen soils.

 

According to the Centers for Disease Control, enzymes attack proteins that make up a large portion of common soil. Enzymatic cleaning solutions also can contain lipases (enzymes active on fats), amylases (enzymes active on starches), and proteases (enzymes active of blood, mucous, feces, and albumin). Enzymatic cleaners are not disinfectants, and proteinaceous enzymes can be inactivated by germicides.4

 

Enzymatic cleaners are so effective, they serve as catalysts that can speed up chemical reactions up to 1,000,000 times. Even detergents with the same surfactants and ingredients without enzymes take at least 10 to 15 times more contact time to achieve an acceptable outcome.5

 

A comparison among three different, widely used healthcare brands provides hard evidence of the real effectiveness of these brands. To compare, film strips were bronze-brown before soaking in enzymatic solution. Temperature, water level, timing and detergent dilution rates were all kept constant and according to manufacturer specifications.

 

Maintaining enzymatic contact time with an instrument surface can be achieved through a variety of options, such as spraying enzymatic foams on instruments at the point-of-use, through liquid or concentration methods by soaking and subsequently, flushing enzymatic solutions through lumens and channels with a flushing system. It is important to note that enzymes work best under certain environmental conditions such as specific temperature ranges, pH levels, and washer settings and in combination with other chemical ingredients.6 IAHCSMM recommends that temperatures should not exceed 140˚F (60˚C), unless otherwise stated by the enzyme manufacturer.

Central sterile processing departments, endoscopy and GI labs, and surgical centers can enhance the effectiveness of cleaning by using enzymatic detergents to reduce manual cleaning times and facilitating the breakdown of different forms of bioburden. Most importantly, utilizing enzymatic products to breakdown and loosen soils on instruments, helps ensure safe outcomes for patients.

 

As always, refer to manufacturer instructions for use (IFU) to ensure that instruments are compatible with enzymatic products.

Integrating ergonomic tools to reduce injury and strain in the packaging and assembly area

Improve productivity, reduce staff injuries, and enhance patient safety with a few simple tools

Medical devices or instruments go through numerous reprocessing steps before they’re deemed sterilized. The packaging and assembly area of the sterile processing department (SPD) is critical in assuring “the sterility of an item” while protecting “the contents until use.” To assure sterility, personnel must follow standards and guidelines to make sure the packaged instrument will not pose risks to patients.

 

The rigorous requirements for preparation for sterilization in ANSI/AAMI ST79:2017 requires that “devices should be cleaned; dried; inspected for cleanliness, flaws, and damage; assembled; and packaged according to the manufacturer’s written IFU.”1  To do so, ANSI/AAMI ST79 states that “there should be sufficient space for clean textile storage (both before and after assembly into packs), an illuminated inspection table, and patching equipment. …the clean work area should include space for magnifying lights; processing tables, which should be made of nonporous materials (e.g., stainless steel), ergonomic, and, preferably, height-adjustable.”

 

The effects of packaging and assembly on the musculoskeletal system

The packaging and assembly process during medical device reprocessing is often very labor-intensive and can lead to musculoskeletal disorders (MSDs). Many times, departments have the best intentions when designing and establishing a packaging and assembly area, only to realize a few more options would have helped improve ergonomics and overall employee satisfaction.

 

Meet ergonomic compliance

ANSI/AAMI ST79 and OSHA ergonomic guidelines2 require height-adjustable workstations. Sterile processing trays are often extremely heavy. Bending and lifting trays onto workstations that are not at comfortable working levels can lead to musculoskeletal disorders. According to OSHA, MSDs “affect the muscles, nerves, blood vessels, ligaments and tendons. Workers in many different industries and occupations can be exposed to risk factors at work, such as lifting heavy items, bending, reaching overhead, pushing and pulling heavy loads, working in awkward body postures and performing the same or similar tasks repetitively. Exposure to these known risk factors for MSDs increases a worker’s risk of injury.”

 

The repetitive motion tasks that are also associated with packaging and assembly can lead to injury and strain. Did you know that ergonomic options go beyond making workstations height-adjustable?

 

Reduce injuries from repetitive tasks

Keeping items easily within reach is key to reducing musculoskeletal disorders from repeated reaching. By employing an integrated pegboard wall, shelving, bins, peel pouch rolls and trays, tape dispensers and more can be designed with the user in mind. Pegboards allow items to be easily moved and adjusted to meet the end users physiological and workflow needs.

 

When it comes to workflow, “providing adequate space for supplies and equipment and designing the layout to facilitate the flow of work through the various steps of preparation contributes to the efficiency and accuracy of the sterile processing staff.”3

 

Meet lighting compliance

In 2013, researchers found that by integrating a few simple ergonomic changes into a department’s design can help improve staff safety. In one department, “a lack of space in the packing area,” led to “…undesirable twists when moving around equipment.”4 By leaving “enough space to establish safe and sound work processes,” the department’s workflow improved.

 

Another area in which prep and pack table design can benefit the end user is integrated lighting. ANSI/AAMI ST79: 2017, 3.3.5.6 states that “adequate lighting of work surfaces should be provided in accordance with the recommendations of the Illuminating Engineering Society of America (IES) for minimum levels of illumination…” The rationale is based on the “importance of speed or accuracy of the work done in the area (the greater the importance of speed or accuracy, the more illuminance needed).”

 

Upon completion of the cleaning process, staff must perform cleaning verification. “Cleaning verification by users should include (a) visual inspection combined with other verification methods that allow the assessment of both external surfaces and the inner housing and channels of medical devices…”

 

Many instruments have very small pieces and tips that look quite similar to the naked eye. It is even more difficult to notice these subtle differences under inadequate lighting. A 2019 study regarding errors in packaging surgical instruments found that “personnel error is the primary reason for packaging errors. Central sterile supply department (CSSD) staff members are not familiar with the clinical utilization of surgical instruments, and therefore it was hard for them to distinguish between instruments with minor differences.”5

 

To avoid errors in packaging surgical instruments, departments can meet compliance with magnifying task lighting. Magnifying task lights improve patient safety by enhancing visual inspection with direct light, as well as allowing technicians to verify cleaning processes and assess any damage to instruments prior to sterilization. Of equal importance, magnification and lighting improve staff safety by reducing eye and neck strain.

 

Find sterile wrap perforations without eye strain

Additionally, when wrapping trays with woven and nonwoven sterile wraps, ANSI/AAMI ST79:2017, 9.5 states that departments must “inspect the wrap to ensure that it is free of defects that could have an adverse effect on the performance of the material.”

 

The International Association of Healthcare Central Service Materiel Management (IAHCSMM) recommends that visual “inspection is performed using a light table that has a light source built into the tabletop to help spot small holes and punctures. As the wrap is passed over the lighted table top, light shines through the small holes and punctures making them easier to identify.”6 By doing so, imperfections and perforations in sterile wrap materials can easily be identified and staff do not have to strain to find small holes.

 

Reduce medical costs while increasing productivity and patient and staff safety

In 2008, researchers sought to connect the costs of injuries and strains on a sterile processing department and in turn, design an intervention to alleviate the number of injuries and straining. The study found that in this particular department, “between 2001 and mid-year 2005, employees in the sterile processing center (SPC) experienced 32 injuries, costing $187,266.00 in direct medical costs (i.e., loss expenses), with strain injuries accounting for 94% of the total expenses and 50% of the total injuries.”7 Many departments are already backlogged with cases and need capacity boosting solutions. Adding injuries and strain to staff only creates further backlogs. By integrating ergonomic solutions in the packaging and assembly area, costs are reduced and throughput is increased. Not to mention, staff productivity and employee satisfaction are boosted as well.

5 ways healthcare reprocessing sinks improve workflow and productivity

How healthcare reprocessing sinks are a better option than commercial stainless steel sinks

In central sterile processing departments, the decontamination area’s reprocessing sinks represent the most critical area in ensuring that instruments are being properly cleaned. While commercial stainless steel sinks are commonly used for reprocessing medical instruments, not all sinks are created equally.

Manual cleaning and disinfection of instruments requires that sinks have either two- or three-basin sections1 to soak, rinse and provide a final rinse with critical water. The American National Standards Institute (ANSI) and Association for the Advancement of Medical Instrument (AAMI) standard ST79:2017 also recommends that sinks have “attached solid counters or adjacent work surfaces on which to place soiled and clean items separately.”

To make the most of the space available in the limited confines of the decontamination area, sinks need to also serve as a workstation. Unlike commercial stainless steel sinks, healthcare reprocessing sinks are designed with the decontamination tasks and users in mind. As such, ergonomics and workflow standards and recommendations are met.

 

5 ways healthcare reprocessing sinks improve productivity and quality

  1. Ergonomics
    Height-adjustable healthcare reprocessing sinks meet Occupational Safety and Health Act (OSHA)2 compliance and reduce musculoskeletal disorders. Central sterile processing personnel heights and physical capabilities vary, making height adjustability a necessity to perform duties optimally. Height-adjustability also comes in varying options. While the overall sink can be height-adjustable, having an attached pegboard or shelf under the sink that moves with the sink, also helps alleviate staff pain from bending and reaching by keeping tools within easy reach.
  2. Protection from aerosolization
    While personal protective equipment (PPE) is a necessity, sinks can also provide another way to ensure the reduction of aerosolization. Aerosols can make contact with personnel from any direction and can transfer microorganisms to personnel. The incorporation of a sink basin splash guard allows for personnel to be able to manually clean instruments without being exposed to dangerous organisms.
  3. Workflow
    Incorporating tools that ensure proper workflow allows healthcare reprocessing sinks to become a training tool. Workflow plates that indicate whether a particular basin is to be used for soaking, rinsing, or a final critical water rinse can be used as a training tool to educate new hires. It also serves as a reminder to veteran personnel when redundant, repetitive tasks can lead to overlook protocols. Workflow plates are also removable for easy cleaning.
  4. Lighting
    ANSI/AAMIST:79 requires adequate lighting of work surfaces.” Ancillary lighting should be considered for areas where instruments are manually cleaned and inspected.” Task lights with magnifying lenses allow personnel to be able to visually verify the cleaning process. Magnifying task lights can be installed on a pegboard with an adjustable arm that meets the ergonomic needs of each staff member for less eye strain and greater inspection capabilities.
  5. Instrument protection
    Tools such as staging panels and sink liners protect the tips of delicate, expensive instruments when more space is needed. By adding a staging panel to an existing sink basin, the sink’s built in counter space is expanded to help stage instruments prior to sterilization. Sink liners in basins and on sink countertops provide a soft-landing area to prevent damage to instruments while they are staged.

3 areas to improve during the manual cleaning phase of medical device reprocessing

3 areas to improve during the manual cleaning phase of medical device reprocessing

How sterile processing and endoscopy/GI departments can improve flushing, inspection/cleaning verification and soaking practices

Flushing, visual inspection/cleaning verification, and soaking are three of the most vital processes in medical device reprocessing in reducing healthcare acquired infections (HAIs) and ensuring patient safety. When these processes are not performed against standards and guidelines, bioburden can easily be left on an instrument for the next patient.

 

3 areas that need improvement

Soaking

Items should be pretreated with an initial cold water rinse with running tap water or an initial soak in cool water and/or a clinical-soil-dissolving pretreatment product (e.g., an enzymatic cleaner or pH neutral detergent). –ANSI/AAMI ST79:2017, 7.6.1

It is well known that the speed in which processes are performed and completed, impact the patient care environment. When robotic instruments and scopes require long soaking times per manufacturer’s instructions for use (IFU) or from delayed reprocessing, maintaining surgical schedules can become jeopardized.

As a result, larger instruments such as robotic devices or flexible scopes, that have IFU soaking requirements, utilize lots of basin space, reducing the amount of space sterile processing departments have to perform other, necessary pre-cleaning functions. The ability for technicians to multitask while instruments are soaking becomes impossible when basin space is not available. And ultimately, without proper soaking, gross soils are not properly broken down, making it difficult to remove bioburden during the cleaning process.

 

Flushing

Thoroughly flushing lumens helps ensure complete surface contact with the solution. If a brush is too large, it will not fit into the lumen; if it is too small, it will not have complete contact with the lumen walls and, consequently, will not clean them thoroughly. –ANSI/AAMI ST79:2017, 7.6.2

While syringes provide a simple, as well as disposable option when flushing, they aren’t entirely effective at removing bioburden. Using a syringe to pull liquid and plunge it into instruments multiple times is not productive. Furthermore, no two techs flush exactly the same way with syringes or spray guns, leading to inconsistent flushing practices.  As a result, “copious flushing” is variable.

Flushing instruments with spray guns is another inefficient cleaning method. Technicians are not able to clean more than one instrument channel at a time, which affects a central sterile processing department’s throughput. Compromised productivity isn’t the only disadvantage when it comes to flushing with spray guns. Spray guns create aerosols, making contaminated liquids even more dangerous when they are converted to vapors, coating staff members in fluids and hard-to-reach areas, putting staff and patients at risk.

 

Visual inspection/cleaning verification

Instruments should be carefully inspected for flaws, damage, debris, detergent residue, and completeness… –ANSI/AAMI ST79:2017, 7.4.1

Endoscope interior

The importance of visual inspection cannot be overstated. The naked eye is unable to detect microscopic bioburden, minute cracks or damage in instruments, even lint inside of lumened channels. If bioburden is left in the channel, the chance of the next patient developing a HAI increases. In 2015, 687,000 patients developed HAIs in the U.S. Of that number, 72,000 of those patients died.1

Visual inspection can be a costly investment. The alternative leaves sterile processing and endoscopy departments to visually inspection instruments and scopes with the naked eye and/or magnification lenses. Unfortunately, eyes and magnification lenses can only visualize easy-to-reach areas in channels. In those hard-to-reach areas of channels, a lot of patient safety risks lurk.

 

3 Ways to Improve Pre-Cleaning Processes

1. Create dedicated soaking spaces

Renovating a decontamination area is costly and not always necessary. Soaking robotic arms, scopes and other larger instruments that demand precious sink basin space also hamper efficiency and the bottom line. Utilizing tools such as smaller mobile sinks, and soaking containers, departments can improve turnover times while meeting compliance.

For example, smaller mobile options, such as the PureSteel Mobile Soaking Station, feature a soaking basin that is wide enough to accommodate soaking requirements for robotics and larger instruments. Its easy-to-drain options also do not require plumbing and can be outfitted with numerous accessories.

Mobile carts that feature vertical storage for multiple soaking containers are built specifically with soaking in mind. By utilizing vertical soaking space, numerous devices can be soaked in containers that are designed to fit the device, as well as easily transport and drain the containers in the smallest overall footprint available.

2. Automate flushing

By utilizing an automated flushing pump, precleaning compliance is achieved through friction, fluidics and contact time with detergents. Automated flushing systems such as the FlexiPump Independent Flushing System, achieve these three objectives through pressurized, copious flushing for specified periods of time. The adaptability of automated flushing systems to connect to virtually any lumened device, allows for a tight connection and a complete flush each time.

Automated flushing also streamlines processes by allowing technicians to multitask. Automated flushing systems can connect and flush multiple devices or ports at once, freeing up technicians to brush complex pieces on devices, clean the surrounding work areas, or start prepping the next tray for reprocessing.

3. Implement visual inspection technology

The best visual inspection intentions are not going to ensure 100% verification of cleaning practices without the flexibility that inspection borescopes offer. Visual inspection borescopes come in many different lengths and diameters that can provide visualization in areas that are hard-to-reach. Inspection scopes are available in fiber-optic and digital models for various resolution needs.to inspect channels, connection ports, distal tips and spaces behind elevator channels. Inspection borescopes can be easily manipulated to identify debris, bio-burden, damage and irregularities that the naked eye and magnification lighting cannot achieve.

To aid technicians in visual inspection, borescopes can also be attached to a monitor so that the borescopes camera can be displayed in larger resolutions to get an even more detailed analysis of cleaning verification, exceeding visual inspection compliance.

 

By implementing these processes, departments can improve compliance, reduce the risk of HAIs, and become more efficient. Analysis of current departmental practices, manufacturer IFUs, and standards and guidelines, can help create a best practices protocol improve staff and patient safety.

Eliminate the Negative Decontamination Stigma

Learn to Love the Decontamination Area of Your Sterile Processing Department

When it comes to medical device reprocessing, the most critical tasks happen in the decontamination area of sterile processing departments. Proper pre-cleaning is the foundational step to patient care. So why do negative stigmas surrounding the decontamination area of sterile processing departments continue to be an issue?

3 Issues that Cause Poor Stigma Regarding Decontamination

  1. Space and equipment issues
    Sterile processing departments are not always outfitted with the right equipment or infrastructure needed to perform the responsibilities that have been assigned. Sterile processing departments may need a three-bay sink and will often have two bays in which to work. As a result, the responsibility falls to the technician to make the equipment achieve both compliance and performance. In departments where space is limited, this becomes a bigger challenge. Poor equipment and departmental limitations can immediately cause the decontamination area to become a place of frustration.
  2. Pain and discomfort
    The decontamination area is a dangerous place to work. Ergonomic hazards to technicians are ripe with injuries from sharps and the body becomes physically tasked when repeatedly lifting trays and bending over sink basins cleaning instruments. Additionally, the decontamination area is hot and sweaty. Add the layers of personal protective equipment (PPE) equipment required to work in the decontamination area and it becomes even more hot and sweaty. Over time, the conditions can put a physical strain on technicians and put them at risk for injury. As a result, it becomes hard to enjoy working in an area that causes pain and discomfort.
  3. Utilizing decontamination as a punishment
    Scheduling can become a major root of poor stigmas in the decontamination area. Managers tend to continue to schedule the same people to work in the decontamination area. Consequently, the long shifts are staffed by the same technicians. Departments that implement frequent rotations of personnel may see improvements in negative attitudes. Additionally, due to the negative perception of working in decontamination, managers will also threaten to punish employees by sending them to work in decontamination. When technicians are overworked and underappreciated in the decontamination area, employee dissatisfaction becomes an issue.

Removing the negative stigma surrounding working in the decontamination area

Removing the stigmas surrounding working in the decontamination area begin with the central sterile processing department leadership. Technicians need to understand and believe that there is no task that is too small when it comes to performing the important work in decontamination. Every channel, every instrument set, every tip is a valuable tool in delivering safe patient outcomes. Technicians, managers, and supervisors are the gatekeepers of patient and staff safety and are responsible for ensuring that each item that comes through the sterile processing department is clean. Remember, every member of the team is vitally important in this process.

Recognizing the demanding work that staff perform in the decontamination area is another step toward eliminating the negative stigmas. When technicians take time and perform their duties meticulously and end their shift with all case carts completed, managers and supervisors should recognize those achievements. Sterile processing professionals can never hear “thank you,” or “good job,” enough.

Sterile processing departments should not underestimate that the element of fear could also be the result of negative perceptions when it comes to working decontamination. If you have never worked in sterile processing, and a technician’s first introduction to the sterile processing department begins in decontamination, the area can seem intimidating. Manufacturer instructions for use (IFU) are quite rigorous with no wiggle room for mistakes. For example, technicians must follow the IFU or suffer the risk to patient and staff safety. Decontamination is a dangerous environment, and proper training for technicians to feel comfortable working in decontamination necessary for successful patient outcomes.

3 tools to help shift negative sterile processing department decontamination perceptions to generate positive results

  1. Identify sterile processing vendors that are actively involved in producing tools for the decontamination space.
    Vendors may provide equipment for decontamination, but if they are not actively engaged in improving that space, they cannot be a long-term partner for addressing the issues you find in decontamination.If departments do not have enough funds allocated in the budget for new sinks, consider sink inserts, which can raise the working level and make your deep sink basins much more manageable. Departments can also consider ergonomic improvements such as anti-fatigue mats. These small tweaks make a difference for the working conditions in decontamination and lead to better staff engagement and satisfaction.
  2. Mobilize and empower sterile processing teams by sharing the responsibility of auditing and improving the decontamination department processes.
    Personnel can help guide departments to implement the best, long-term fixes for their department. By seeking staff input, department leaders can create a collaborative environment in which to celebrate working in decontamination. Department leaders who consistently communicate and educate regarding the importance of decontamination, immediately create a more welcoming atmosphere. Education is a critical pillar to building a solid decontamination area. Sterile processing departments can experience great benefits from partnering with local IAHCSMM chapters and exchanging ideas and information. When departments sponsor decontamination-related education, it sends a signal that the decontamination area is important.
  3. Find a decontam champion!
    In sterile processing departments where negative resentments around decontamination persist, your champion, when mobilized, will help others learn to love decontamination. Involving the decontamination champion can help departments when evaluating new product improvements. Decontam champions can also create great partnerships with educators when performing decontamination in-service training. If staff see decontamination as a dead-end, it will begin to affect the entire team. However, if departments can provide routes to improve staff mentalities with a champion program, sterile processing department leadership demonstrates that personnel talents, knowledge, skills, and abilities are recognized. A champion can be a powerful thing.

Stigmas surrounding the decontamination area can always end with sterile processing leadership personnel. If you love decontamination, then your team will learn to love it as well. You can never overcommunicate the significance that decontamination holds in the sterile processing department.

Solutions for easily boosting capacity in backlogged sterile processing departments

It is a scene that is all too familiar in sterile processing departments: case carts pilling up in decontamination, while scheduled surgeries are delayed or postponed due to backlogs in reprocessing. Those backlogs are often created by bottlenecks that can easily be adjusted or eliminated with a few uncomplicated solutions.

 

Sterile processing backlog area 1: Soaking

The most common sterile processing bottlenecks occur during the soaking and precleaning processes.

Soaking and precleaning is critical for patient safety. ANSI/AAMI ST79: 2017, 7.5.1 states “presoaking instruments moistens and loosens the soil, thus making the cleaning step more effective and efficient.”1 Additionally, device instructions for use (IFU), such as robotics, can require soak times of up to 30 minutes. Flexible and rigid scopes can be even more demanding when delayed reprocessing occurs, requiring a minimum of one hour of soaking, and up to ten hours for some gastrointestinal scopes.²

Many reprocessing departments do not have enough sink basins to dedicate tor instruments with extended soak times. Additionally, many sink basins are not wide enough to accommodate soaking larger instruments or trays, leading to more reprocessing delays.

Robotic instruments and scopes are inherently difficult to clean. Properly soaking the instrument loosens and removes gross bioburden to make the cleaning and rinsing process more effective. If proper protocols are not followed during the precleaning process, that can add additional delays to an already bottlenecked process. So how do departments prioritize basin space and while meeting standards and guidelines?

Options to accommodate medical device soaking requirements

Mobile carts are a quick fix for departments that do not have extra space or resources for a renovation. Departments can create a dedicated soaking space during peak processing times by incorporating a sink insert into a mobile cart or integrating a mobile sink basin. Sink inserts and mobile carts are available in a variety of sizes to accommodate robotics, rigid and flexible scopes, as well as separate areas for ocular instrument reprocessing.

Mobile carts are available in multi-tier options so that departments can soak multiple sets of instruments at once within a small footprint. The mobility of the carts also makes it easy to store the cart and sink inserts when not in use or utilize it for vertical storage options as a place to store soaking containers when not in use.

 

Sterile processing backlog area 2: Flushing

Properly flushing instruments during the precleaning process can create backlogs when volume of lumened instruments and processes for flushing are considered.

Lumens must be flushed with highly efficient practices, so time-saving measures can be difficult to implement without the expense of quality. Contact, friction, and fluidics are necessary to properly remove bioburden from lumened instruments and scopes.

  • Specific contact times are required by detergent IFUs to effectively dissolve and loosen bioburden deposits such as blood, fat, and tissue
  • Friction, by brushing or flushing, facilitates the separation of bioburden from its points of attachment on internal device surfaces
  • Often, brushing or flushing alone does not remove hard, stuck-on bioburden. By integrating fluidics, or a high volume of fluid under pressure, those volumes ensure that detergents and residues are completely flushed from interior channels and lumens

Traditional tools to flush lumened devices such as syringes and spray guns may be a simple, cost-effective option. However, cost-effectiveness should be balanced with efficiency and effectiveness.

Syringes may be a simple, traditional solution. But pulling liquid and plunging it into each instrument for a specified number of times is a time-consuming process. And no two technicians’ flush instruments in the same way, every time. That can lead to practice discrepancies from shift to shift.

Similar to syringes, spray guns cannot clean more than one channel at a time, and require technicians to use both hands, which decreases the ability for technicians to multi-task.

Alternatives to flushing with syringes and spray guns

Automated flushing systems effectively address the issue of throughput by enabling simultaneous flushing for multiple channeled items or ports with much less connection or disconnection time. One automated system can allow technicians to flush up to 5 items at a time. Output can be doubled or even tripled multiple systems are installed at sinks.

By automating the flushing process, departments can also ensure that devices are consistently flushing at the proper volumes per instrument IFU and ANSI/AAMI ST79:2017 flushing and rinsing standards. Automated systems provide options for flushing for specific amounts of time at specific volumes so that contact time IFUs are met. Additionally, treated and untreated water and cleaning solutions can be integrated into the system to aid in loosening bioburden and assuring pre-cleaning protocols are met.

Automated systems are adaptable to a wide variety of instruments:

  • Orthopedic
  • Endoscopic
  • Robotic
  • Ocular
  • Laparoscopic devices
  • Suction tips
  • And more

These flushing systems ensure automated, consistent flushing for your full channeled instrument inventory.

 

Reducing reprocessing bottlenecks NOW

When departments are already challenged with time constraints, fast, affordable solutions are the easiest way to increase capacity. Large-scale renovations are not always necessary. Instead, simple tools such as mobile carts, sink inserts, and automated flushing systems can be easily installed and implemented to alleviate backlogs and reduce processing times. More care can be taken to deliver safer outcomes for staff, instruments, and patients when departments do not feel rushed to provide case carts quickly.

3 Ways Height Adjustable Sinks and Tables Improve Sterile Processing Workflow

According to the Occupational Safety and Health Administration (OSHA), “Ergonomics is the practice of designing equipment and work tasks to conform to the capability of the worker.” The ultimate purpose of this practice is to prevent injuries to staff while they are performing their tasks.

Preventable injuries create a host of negative consequences to workers and their employers, including:

  • Pain and an inability to perform tasks
  • Healthcare and worker’s compensation costs
  • Temporary staffing costs
  • Possible turnover and retraining costs
  • Lost productivity and morale
  • Lost revenue

OSHA’s Occupational Safety and Health Act of 1970 mandates that employers provide workplaces that are “free from recognized hazards that are causing or are likely to cause death or serious physical harm” to employees.

 

Sterile processing worker and workflow hazards

OSHA says hospitals are among the most hazardous places to work. During the 12 months of 2014, the Bureau of Labor Statistics recorded 294,000 nonfatal work-related illnesses and injuries in U.S. hospitals.

Ergonomic hazards in sterile processing departments (SPDs) are typically musculoskeletal disorders (MSD) associated with bending, reaching and repetitive motion tasks. Specifically, when working in sinks, technicians must sort, take apart, and manually pre-clean each device or instrument, and then prepare it for disinfection or sterilization processes.

These tasks are performed hundreds of times a week, and have typically been done while standing at static, deep sinks designed for the restaurant industry. Workers spend hours on their feet each day inspecting instruments and trays and wrapping each tray for sterilization. These tasks are often performed at a non-adjustable workstation that is not designed with staff safety in mind.

 

Focus on sterile processing ergonomics

Whether they are performed in the GI department or the sterile processing department, reprocessing tasks are rife with potentially uncomfortable activities. These range from prolonged standing in one place, to awkward postures and repeated extreme bending, or performing repetitive wrist and arm movements that can cause pain and numbness. Some ergonomic solutions were designed to be added to existing department equipment. However, when a department is ready to remodel, or a new facility is being built, an opportunity is created to identify ergonomic hazards and address them more thoroughly through better designed pre-cleaning workflows and permanently installed injury-prevention solutions.

OSHA has provided specific “possible solutions” to help address ergonomic injuries in the SPD (also known as Central Supply). They are intended to be applied to other similar work areas in the hospital. Among other suggestions, they include:

  • Redesign workstations so packaging and equipment can be reached while maintaining elbows close to the body
  • Use height-adjustable work surfaces
  • Minimize prolonged overhead activity (to avoid reaching over shoulder height)

In addition, the American National Standards Institute (ANSI) and the Association for the Advancement of Medical Instrumentation (AAMI) issued a joint document, the ANSI/AAMI ST79: 2017, 3.3.6.1.3,  which offers more detailed recommendations for setting up a decontamination area:  “Ergonomic factors affecting worker safety and comfort should be considered when designing work spaces in the decontamination area, including: a) adjustable counters, sinks, and work surfaces positioned at heights that take into account the average height of the employees and the tasks to be performed at each location.”

The standard also states:

“Designing the area to facilitate efficient work flow and to provide adequate space for necessary equipment can reduce the potential for cross-contamination and enhance efficiency. Considering ergonomic factors during the design phase can help prevent worker injury.”

 

All utility sinks are not healthcare reprocessing sinks!

Every effort should be made to make the sink area station as ergonomic as possible since it is the primary pre-cleaning work site. In the past, healthcare facilities had few options for sinks that could be used to reprocess devices. Their stainless steel sinks, not designed for healthcare functions, were unnecessarily deep. When used for healthcare instrument reprocessing activities, they have been a source of MSD of the hip, back, shoulder, and arm.

 

All prep and pack tables are not equal

Workstations in the assembly area of sterile processing are one of the most critical pieces of equipment required to properly inspect and package instruments prior to sterilization. Workstations without ergonomic considerations are a culprit in back, hip, shoulder, arm, and eye strain.

Incorporating a height-adjustable countertop as well as an attached pegboard allows users to raise or lower the workstation to meet their height while also allowing supplies and tools to be within easy reach. Attached task lights also move with the height-adjustability of the workstation, aiding in reducing eye and neck strain during inspection tasks.

Healthcare manufacturers identified the need to supply more ergonomic equipment and are developing better tools for these critical functions.

 

Workflow is essential to productivity

It is important to understand the flow of tasks and activities, the challenges and bottlenecks, the specific items being processed, and which specific processes are being used. In addition, the workflow requirements of all reprocessing stakeholders must be considered: Technicians, facility management, and the infection control department. Everyone should express their objectives and challenges in order to design the best solution for all. Planning for inventory growth and turnover is also a consideration for this area.

 

Three ways height-adjustable sinks and workstations improve workflow

1.  Height-adjustable sinks and workstation allow for less strain and minimize overhead activity

A height-adjustable sink or workstation allows fully customizable placement of the tools for individual technicians and brings items closer to the user. A height-adjustable pegboard and other movable hanging storage systems bring tools to users’ fingertips. Height adjustment on sinks and workstations enable the optimal ergonomic working height setting and head tilt for virtually any user, to help avoid strain and injury.

2.  Ability to rotate workers through repetitive tasks

The ability to instantly customize the height and reach of a sink or workstation electronically with the push of a button, makes it fast and easy to rotate staff members with different ergonomic needs and capabilities at the sink and workstation.

3.  Reducing the Clutter Factor

There is a strong indirect correlation between clutter and productivity in any workplace. Cluttered workstations add to workers’ time and effort, add to personal stress and morale, and can eventually affect the quality of work. In healthcare reprocessing areas, poor job quality can have a much more serious consequence: It can affect worker and patient health and safety.

Reprocessing areas are typically complex environments, with numerous cleaning tools, instructions, jugs of chemistries, device parts, packaging and assembly supplies in and around the work areas. Clutter and disorganization are very common conditions in these work areas because of the inherent nature of the work. A messy workspace requires more reaching, untangling and other musculoskeletal activity, which adds to the ergonomic stressors already in play. Additionally, heavily cluttered areas also carry the risk of becoming a breeding ground for organisms that can contaminate surfaces, tools and devices.

 

Improve your sterile processing workflow with the right tools

Before selecting a sink or workstation intended to be used as a medical device reprocessing tool, hospital decision-makers must consider this: Are they using a local fabricator or supplier with general sink design experience, or consulting a healthcare specialty manufacturer with extensive research and observation-based knowledge of the reprocessing function and its related requirements?

OSHA has made it clear that attention to proper ergonomics helps reduce injuries and discomfort that can affect a worker’s ability to function, and that identifying and addressing ergonomic issues should be a mandatory practice for all industries. Providing an ergonomic workplace can also help employers reduce healthcare and other costs related to avoidable injuries, so it is in their best interest to do so.

By installing and using a powered, auto-height adjustable healthcare reprocessing sink or prep and pack workstation, and providing ergonomic storage to organize the immediate workspace, sterile processing management can eliminate unnecessary pain and costs while developing a safe, efficient and highly productive workflow to better support clinical areas of their hospital. These industry-specific tools provide a simple and valuable solution for healthcare providers.

Central sterile processing education and training are key to reducing HAIs

For decades, reusable medical devices have been the culprit of healthcare-associated infections (HAIs).  Each day, approximately 1 in 31 U.S. patients has at least one infection in association with his or her hospital care,1 underscoring the need for improvements in patient care practices in U.S. healthcare facilities.

Sterile processing departments play a crucial role in patient safety outcomes. The risk of infection and death increases dramatically if instruments are not thoroughly cleaned and sterilized. In addition to understanding the patient safety element of sterile processing, technicians are also required to understand every inch of a surgical instrument to thoroughly clean and sterilize the device for use on the next patient.

Properly trained sterile processing technicians are critical

Better patient care begins with properly trained sterile processing technicians. Technicians require the most up-to-date information to properly do their jobs.

As medical procedures evolve, so do technology and instrumentation. Keeping up to date with reusable medical devices advancements requires continuous knowledge. Risks increase without the latest industry standards and manufacturer instructions for use (IFU). The safety risk to staff and patients cannot be understated.

According to the United States Bureau of Labor Statistics, there are 50,550 instrument specialist technicians, with job growth expected to increase 20% by 2022.2 That means there are 50,550 different ways an instrument could be cleaned. Inconsistent cleaning practices can be avoided, and patient outcomes can be improved by providing training and education on best practices, national standards, and manufacturer IFU. These must become a mandatory part of every sterile processing department’s quality protocols.

Consistent sterile processing training improves outcomes

Departmental best practices can be improved by consistently providing training and in-service opportunities to staff. This helps avoid medical device reprocessing issues such as dirty instruments that can lead to HAIs.

Sterile processing products such as sterilizers, automated flushing pumps, inspection technology and more are constantly evolving to improve processes and effectively clean and sterilize instruments. Best practices are followed more consistently, and technicians are more confident in the ability to perform their duties when they are properly trained.

Providing ongoing education and certification opportunities to all staff is another way a department can improve not only patient safety but staff safety as well. Educational offerings come in a variety of options, but we will focus on two of the most common: Continuing Education and Certification.

Sterile processing continuing education

Continuing Education (CE) programs offered by facilities, associations, and vendors provide departments with the opportunity to keep up to date with:

  • The latest industry trends
  • Standards and regulations
  • Recommended practices
  • Manufacturer IFU

Vendors and industry associations are a great resource when it comes to obtaining CE credits. This year has also seen an increase in virtual opportunities to easily receive CEs. Social media platforms like Facebook and LinkedIn have many sterile processing professional groups where CE resources are shared. Vendors and industry associations such as IAHCSMMASTAORNSGNA and others also have resources on their website in which to find CE opportunities.

Sterile processing certification

Professional certification requires technicians and staff to take educational courses and exams to assure they have met competency-based standards to perform their jobs. Certification opportunities abound through IAHCSMMCBSPD, community and junior colleges, and other outlets.

Several states understand the importance of the critical tasks that sterile processing technicians are faced with and now require sterile processing technicians to become certified. To become a sterile processing technician in Connecticut, New Jersey, New York and Tennessee, you must be certified. Certification requires technicians to take courses in order to pass a certification exam.  Certification ensures departments are performing their duties through high standards.

CBSPD offers the following certifications:

  • Certified Sterile Processing and Distribution Technician (CSPDT)
  • Certified Ambulatory Surgery Sterile Processing Technician (CASSPT)
  • Management in Sterile Processing (CSPM)
  • Flexible Endoscope Reprocessors (CFER)
  • Certified Surgical Instrument Specialist (CSIS)

IAHCSMM offers the following certifications:

  • Certified Registered Central Service Technician (CRCST)
  • Certified Instrument Specialist (CIS)
  • Certified Endoscope Reprocessor (CER)
  • Certified Healthcare Leader (CHL)
  • Certified Central Service Vendor Partner (CCSVP)

In addition to enhancing patient and staff safety, sterile processing training, education, and certification opportunities provide an outlet to network with other professionals to learn from each other.

Establish a continuous sterile processing training methodology in your department for future growth and adherence to best practices. Now is the time to support your technicians with additional learning opportunities to strengthen the team and improve patient outcomes. Those are the keys to reducing HAIs!
