RESUMO
To provide a safe environment, behavioral health settings must adhere to "ligature-resistant" protocols for patients at risk of harm to themselves or others. However, certain bathroom ligature-resistant fixtures alter environmental controls, such as sinks and showerheads, and increase the risk of water-borne pathogens due to low water output settings, highlighting the importance of an interdisciplinary water management program. We describe how ligature-resistant water fixtures may have been associated with a possible case of hospital-associated Legionellosis.

Hospitals caring for patients with high-consequence pathogens may need to safely manage large volumes of category A waste. Using biological indicators to assess for successful sterilization, autoclave cycle parameters that would inactivate 4 categories of waste were identified and validated utilizing a STERIS Amsco 630LS Steam Sterilizer.

OBJECTIVE: To determine if the high-level personal protective equipment used in the treatment of high-consequence infectious diseases is effective at stopping the spread of pathogens to healthcare personnel (HCP) while doffing. BACKGROUND: Personal protective equipment (PPE) is fundamental to the safety of HCPs. HCPs treating patients with high-consequence infectious diseases use several layers of PPE, forming complex protective ensembles. With high-containment PPE, step-by-step procedures are often used for donning and doffing to minimize contamination risk to the HCP, but these procedures are rarely empirically validated and instead rely on following infection prevention best practices. METHODS: A doffing protocol video for a high-containment PPE ensemble was evaluated to determine potential contamination pathways. These potential pathways were tested using fluorescence and genetically marked bacteriophages. RESULTS: The experiments revealed existing protocols permit contamination pathways allowing for transmission of bacteriophages to HCPs. Updates to the doffing protocols were generated based on the discovered contamination pathways. This updated doffing protocol eliminated the movement of viable bacteriophages from the outside of the PPE to the skin of the HCP. CONCLUSIONS: Our results illustrate the need for quantitative, scientific investigations of infection prevention practices, such as doffing PPE.
