Key Takeaways: Revised Guideline for Hand Hygiene


Revised Guideline for Hand Hygiene 

New Recommendations:

Actions should be taken to prevent waterborne pathogen dispersion during use of hand hygiene and surgical scrub sinks.  

Dispersal of water and potential waterborne pathogens may be minimized by:

  • Installing sinks with basins deep enough to minimize splashing
  • Minimizing surface area in contact with water
  • Providing adequate space between sinks and patients, sterile items, and medication preparation
  • Installing splash guards where appropriate
  • Locating faucets so that they do not discharge directly above the drain
  • Adjusting water pressure to reduce forceful discharge into the sink at maximum flow
  • Implementing routine cleaning of sinks and surrounding areas.


Sinks, faucets, and drains are common sources of Pseudomonas aeruginosa and other gram-negative bacteria. Forming or utilizing an existing water management team to develop a plan for reducing bacterial contamination of sinks, faucets, and drains is key to preventing pathogen transmission.
