New research suggests medical instrument processing personnel may be exposed to tissue, blood, and patient fluids

Dec. 2, 2021

New data suggest that personnel who process reusable medical instruments and equipment may be frequently exposed to tissue, blood, and patient fluids even when wearing recommended personal protective equipment (PPE). The findings, which appear in the American Journal of Infection Control (AJIC), the Journal of the Association for Professionals in Infection Control and Epidemiology (APIC), detail the results of a pilot project evaluating splash generation during processing activities in equipment decontamination areas.

The first real-world evaluation of PPE effectiveness for sterile processing personnel, the project found that PPE, even when properly donned and doffed, does not provide adequate protection from routine sterile processing activities. The authors highlight the need for more research to support evidence-based guidelines and instructions for safe processing.

To conduct their research, Ofstead and colleagues affixed moisture-detection paper to environmental surfaces and PPE in the sterile processing department (SPD) of a large, urban hospital. Highly trained, processing personnel then simulated performance of routine reprocessing tasks, including filling a sink, brushing a ureteroscope, and using a power sprayer when rinsing the sink basin. Following completion of the tasks, researchers detected splashes and droplet dispersal of at least three, and in some instances up to five, feet from the sink. This dispersal was associated with all but one of the simulated sterile processing activities. Additionally, currently recommended PPE did not adequately protect SPD personnel from exposure to water and cleaning solutions.

The findings have implications for thousands of SPD personnel at hospitals, clinics, and ambulatory surgery centers, including the nearly 40,000 members of the International Association of Healthcare Central Service Materiel Management (IAHCSMM)—the professional association for certified sterile processing professionals.
