Sinks have been introduced near patients to improve hand hygiene as part of infection prevention and control measures, say Fucina, et al. (2024), who add that sinks are a known reservoir for Gram-negative bacterial pathogens in particular and their removal to prevent bacterial infections in intensive care patients is currently recommended by several international guidelines.

In this study, healthcare workers in 15 intensive care units (ICUs) in Germany were given the opportunity to complete an anonymous survey on the use of sinks between August 2022 and January 2023. Observations were then made in three participating ICUs to determine the frequency and reason for contact with the sink.

258 questionnaires were returned (nurses 87%). 90% found it useful to very useful to have a sink in the patient room, and 56% reported using it daily for hand hygiene. The researchers observed 33 contacts between nurses and sinks over 17 hours. In 20 out of 33 cases (60%), the sink was used for waste disposal. In 3 out of 33 cases (10%), it was used for handwashing.

Sinks are still used for daily care in intensive care units. Educational interventions in existing buildings to minimize risk through “sink hygiene” (such as separation of sinks for water disposal and uptake) can make an important contribution to infection prevention, the authors say.
