Healthcare-associated infections (HAIs) affect an estimated 1.7 million individuals and result in 99,000 deaths annually in American hospitals. With its role in hand washing accepted as perhaps our most reliable means for reducing HAI risk, hospital tap water has also been recognized as a source of such infections. Peer-reviewed literature has demonstrated that hospital tap water contains microbial pathogens, and that biofilm in water systems resists disinfection and delivers pathogenic organisms to the point of care. At-risk patients are susceptible to infection through direct contact, ingestion, and inhalation of waterborne pathogens. Systemic water treatment technologies reduce levels of recognized waterborne pathogens; however, they cannot eradicate biofilm within healthcare facility plumbing. Existing point-of-use (POU) filtration technologies have been reported to interrupt clinical outbreaks of infection due to recognized waterborne pathogens in the health care environment, and can represent a critical component of a comprehensive infection control strategy, particularly when targeted for patients at high risk.

The Occupational Safety and Health Administration (OSHA) says that more U.S. workers are injured in the healthcare industry than any other. This sector has one of the highest rates of work-related injuries and illnesses, and in 2010, it reported 653,900 injury and illness cases. Also for that year, the latest year for which data are available, OSHA says the incidence rate for work-related nonfatal injuries and illnesses in healthcare was 139.9; by comparison, the incidence rate for nonfatal injury and illnesses in all private industry was 107.7. That's a lot of injuries and illness despite the fact that the General Duty Clause of the legislation that created OSHA requires employers to provide workers with a safe workplace that does not have any known hazards that cause or are likely to cause death or serious injury.

A renewed interest in the healthcare environment and to what degree surface contamination contributes to the spread of infectious pathogens is driving a growing body of research in this area. The following article will take a look at what we know about various aspects of environmental hygiene from the scientific literature.
