Infection control in hospitals is a big job. Every health care administrator, physician, department head, and director of materials management is concerned about improving procedures and equipment to combat hospital-acquired infectious diseases. Adherence to proper hand washing technique reduces nosocomial infections, and recent studies have shown that there are methods to improve staff compliance with hand hygiene.
Isolation procedures are another concern, both in architectural design and staff procedures. Surface disinfection can be a big factor in reducing infection in hospitals, especially in intensive care units and isolation wards. Not only do shoddy practices or unclean surfaces cause infections for patients and the general public, but hospital workers themselves are at high risk for infectious diseases. Newer products such as hygienic wall coverings and antimicrobial light sources can reduce surface-based pathogens in hospital environments. As science advances, the industry responds by producing new safety-enhancing products for medical facilities large and small.
