What is Extended Use?
Extended use refers to the practice of wearing the same personal protective equipment (PPE), such as masks or gowns, for multiple patient encounters without removing it between patients. This approach is often employed during pandemics or outbreaks when supplies are limited. The goal is to conserve resources while still maintaining an acceptable level of
infection control.
What is Limited Reuse?
Limited reuse involves safely removing and storing PPE for later use. This practice is implemented when supplies are critically low. It requires adherence to protocols to prevent contamination and maintain the integrity of the PPE. Items like N95 respirators are common candidates for limited reuse, provided they retain their
filtration efficiency and fit.
Why Are These Practices Important?
During infectious disease outbreaks, such as the
COVID-19 pandemic, healthcare systems can become overwhelmed, leading to shortages of critical PPE. Extended use and limited reuse strategies can help mitigate these shortages by maximizing the availability of resources. These practices ensure that healthcare workers remain protected while caring for patients.
What Are the Risks of Extended Use and Limited Reuse?
While these practices help conserve resources, they also come with risks. Extended use can lead to discomfort and reduced effectiveness of PPE due to moisture buildup or structural degradation. Limited reuse requires strict protocols to avoid
cross-contamination and ensure the PPE maintains its protective qualities. Failure to adhere to these protocols can increase the risk of
healthcare-associated infections.
How to Implement Extended Use Safely?
To safely implement extended use protocols, healthcare facilities should establish clear guidelines. This includes training staff on the correct donning and doffing procedures, recognizing the signs of PPE failure, and understanding when it is safe to continue using the same equipment for multiple encounters. Regular monitoring and feedback are essential to ensure compliance and safety. What Are the Guidelines for Limited Reuse?
Guidelines for limited reuse involve clear protocols for the safe storage and handling of PPE. Respirators, for example, should be stored in a clean, breathable container between uses. Facilities must determine the maximum number of reuses based on the type of PPE and the specific conditions of use. Both the
CDC and the
WHO provide recommendations to help guide these practices.
What Innovations Support Extended Use and Limited Reuse?
Technological advancements and innovative practices are crucial for improving the safety and efficacy of extended use and limited reuse. For instance, decontamination technologies using ultraviolet light or hydrogen peroxide vapor can allow for the safe reuse of certain PPE. These innovations help extend the life of critical protective equipment without compromising safety. Conclusion
Extended use and limited reuse are vital strategies during infectious disease outbreaks, helping to conserve essential resources while protecting healthcare workers. Although these practices carry inherent risks, adherence to strict protocols and leveraging technological innovations can mitigate these issues. Understanding and implementing these strategies is crucial for effective
pandemic response and maintaining the resilience of healthcare systems.
