Healthcare-associated infections (HAIs), generally defined as bacterial, viral, or fungal infections contracted by patients while receiving medical treatment, are a potentially major hazard for residents of nursing homes and other long-term care facilities (LTCFs). As many as 2.8 million LTCF patients may contract HAIs, some of them fatal, every year. A group of epidemiologists recently revised the definitions used in the surveillance of HAIs, providing new tools to document and track infections. The Centers for Disease Control and Prevention (CDC) has also issued new guidelines to help LTCF’s monitor HAIs. These new tools will hopefully help reduce the development and spread of infections among nursing home residents.
HAI Surveillance Definitions
In the October 2012 issue of the Society for Healthcare Epidemiology of America’s (SHEA) journal, Infection Control and Hospital Epidemiology, a panel of experts present a new set of definitions for use in monitoring LTCF infections. The existing set of definitions, known as the McGeer criteria, date back to 1991.
A group of experts led by Allison McGeer published a set of definitions in the February 1991 issue of the American Journal of Infection Control. The purpose of the McGeer criteria was to establish a uniform set of guidelines to monitor infections in nursing homes, such as standards for identifying newly-contracted or worsened acute infections that require monitoring.
According to the paper containing the revised definitions, the McGeer criteria work well in nursing homes providing non-acute care to older residents, but they do not necessarily address concerns faced in LCTFs providing acute care and care to younger patients. New types of nonhospital treatment facilities have appeared since 1991, so newer criteria for identifying and tracking HAIs is necessary.
