by Importance of Cleaning Medical Devices
Cleaning medical devices properly is one of the most important aspects of infection prevention and patient safety in any healthcare facility. When medical equipment and instruments are not cleaned correctly, it can allow harmful bacteria and other microbes to survive and potentially spread between patients. This poses serious risks such as surgical site infections, hospital-acquired infections, and even sepsis – which can lead to increased treatment costs, extended hospital stays, and in worst cases, patient deaths. Cleaning medical devices according to established protocols and guidelines is the most basic and effective way to reduce healthcare-associated infections.
Cleaning Protocols and Standards
All healthcare facilities must develop detailed, step-by-step cleaning protocols specific to each type of medical device used in patient care areas. These cleaning procedures should be based on national standards and regulatory guidelines such as those from organizations like the Centers for Disease Control and Prevention (CDC), Occupational Safety and Health Administration (OSHA), and Association for the Advancement of Medical Device Cleaning Instrumentation (AAMI). Protocols should specify the proper cleaning agents, equipment, protective gear, and disinfectants required, as well as precise instructions for each cleaning step. Regular audits help ensure staff strictly follow the established protocols every time. Unannounced evaluations of cleaning practices are also important to maintain compliance.
Training and Competency Assessment
It is critical that all staff involved in cleaning and disinfecting medical devices receive thorough initial and ongoing training on the approved cleaning protocols. They must demonstrate competency in following each step properly before being allowed to perform Medical Device Cleaning independently. Competency assessments should occur at least annually and anytime protocols are updated. Refresher training is also necessary if audits reveal any lapses in compliance. Designated staff should be fully trained and competent to audit others as well. Ensuring cleaning staff are well-educated and their skills are constantly evaluated helps optimize cleaning quality and reduces procedural errors.
Pre-Cleaning at Point of Use
The first and most important step of any medical device cleaning process begins at the point of use – immediately after removal from a patient. Known as pre-cleaning, this involves wiping away any visible contamination like blood or bodily fluids from the item before it dries. Leaving residues to dry makes them much harder to remove in the final cleaning stage. Pre-cleaning should take place in the patient treatment area using appropriate disinfectant wipes or spray solutions. Once wiped down, items can be temporarily stored in a covered container for transport to the central processing area for thorough cleaning and disinfection. Point-of-use pre-cleaning saves time and effort later in the process.
Proper Cleaning Methods and Tools
The specific tools, equipment, and chemicals used for medical device cleaning should effectively remove all proteinaceous material, contaminants, and microorganisms. Manual cleaning typically utilizes washers, brushes, and ultrasonic cleaners along with enzymes, detergents, and disinfectants. Automated washer-disinfectors provide highly effective cleaning through precise temperature, water pressure, concentration of cleaning chemicals, and mechanical action. Whichever method is used, it must be validated to show consistent and reliable removal of all soil and microbes, especially those posing the greatest infection risks like C. difficile spores. Proper rinsing is also crucial to avoid residue problems. Proven cleaning tools and chemistries backed by validation studies optimize disinfection outcomes.
Quality Control Measures
Ensuring consistent quality in medical device cleaning requires a robust quality control plan including verification, monitoring, corrective action, record-keeping, and ongoing process improvement strategies. Key quality checks involve using biological indicators (BIs), chemical indicators, and adenosine triphosphate (ATP) testing to confirm cleaning efficacy. BIs containing bacterial spores assess whether the cleaning process achieves sterility. Chemical indicators detect parameters like temperature and concentration. ATP testing quantifies residual organic matter to verify cleaning effectiveness. Outcome measures like infection rates further validate quality over time. Prompt response is needed if any audits, inspections or tests signal issues. Continuous quality improvement keeps standards high. An effective quality system promotes patient safety and regulatory compliance.
Consistent, compliant cleaning is indispensable for preventing harmful infections associated with medical equipment and surgical procedures. By establishing evidence-based protocols, providing robust staff training programs, instituting pre-cleaning steps at the point of use, using recommended cleaning methods and tools, and implementing a comprehensive quality assurance system, healthcare facilities can maximize the disinfection of reusable medical devices. This improves patient outcomes and reduces costs from healthcare-associated infections. A diligent, high-quality approach to medical cleaning sets the stage for improved safety, outcomes and value across the entire care continuum
