An unwanted visitor. Aggressive infection control strategies are needed to shorten the hospital visit of the easily spread norovirus.
Norovirus is the name for a group of Norwalk-like viruses that cause acute gastroenteritis of rapid onset. A recent outbreak at a tertiary care facility in Alberta provided an opportunityfor staff and management to review their outbreak protocol and improve their infection prevention and control procedures. The outbreak caused illness in 32 of 73 exposed patients as well as 42 staff members. None of the infected patients or staff developed complications. The source of norovirus contamination was probably associated with a symptomatic food services staff member serving food cafeteria style in a satellite patient dining room. Food service procedures and serving techniques were reviewed; although no breaks in technique were identified, correct food handling procedures were reviewed with staff. Subsequent patient and staff cases were probably related to the cross contamination of environmental surfaces and patient care equipment. The director of nursing and the infection control practitioner led the investigation and management of the outbreak. An Outbreak Management Committee was also formed to reinforce routine infection prevention practices and implement infection control strategies. Communication strategies for staff, patients and visitors were quickly devised and implemented. Gaps in the outbreak protocol were identified and resolved promptly Four permanent changes were made: the use of alcohol hand rinse in designated locations; the development of a comprehensive e-mail to facilitate site-wide communication; the development of teamwork checklists and accountabilities; and the establishment of criteria for use in outbreak situations to proactively determine essential and non-essential therapies and treatments.
