Popis: Long-term care facilities (LTCFs) may be defined as institutions that provide health care to people who are unable to manage independently in the community.1 This care may be chronic care management or short-term rehabilitative services. The term nursing home is defined as a facility licensed with an organized professional staff and inpatient beds that provides continuous nursing and other services to patients who are not in the acute phase of an illness. There is considerable overlap between the 2 terms. More than 1.5 million residents reside in United States (US) nursing homes. In recent years, the acuity of illness of nursing home residents has increased. LTCF residents have a risk of developing health care-associated infection (HAI) that approaches that seen in acute care hospital patients. A great deal of information has been published concerning infections in the LTCF, and infection control programs are nearly universal in that setting. This position paper reviews the literature on infections and infection control programs in the LTCF. Recommendations are developed for long-term care (LTC) infection control programs based on interpretation of currently available evidence. The recommendations cover the structure and function of the infection control program, including surveillance, isolation precautions, outbreak control, resident care, and employee health. Infection control resources are also presented. Hospital infection control programs are well established in the US. Virtually every hospital has an infection control professional (ICP), and many larger hospitals have a consulting hospital epidemiologist. The Study on the Efficacy of Nosocomial Infection Control (SENIC) documented the effectiveness of a hospital infection control program that applies standard surveillance and control measures.2 The major elements leading to a HAI are the infectious agent, a susceptible host, and a means of transmission. These elements are present in LTCFs as well as in hospitals. It is not surprising, therefore, that almost as many HAIs occur annually in LTCFs as in hospitals in the US.3 The last 2 decades have seen increased recognition of the problem of infections in LTCFs, with subsequent widespread development of LTCF infection control programs and definition of the role of the ICP in LTCFs. An increasingly robust literature is devoted to LTC infection control issues such as the descriptive epidemiology of LTCF infections, the microbiology of LTCF infections, outbreaks, control measures, and isolation. Nevertheless, there is as yet no SENIC-equivalent study documenting the efficacy of infection control in LTCFs, and few controlled studies have analyzed the efficacy or cost-effectiveness of the specific control measures in that setting. Although hospitals and LTCFs both have closed populations of patients requiring nursing care, they are quite different. They differ with regard to payment systems, patient acuity, availability of laboratory and x-ray, and nurse-to-patient ratios. More fundamentally, the focus is different. The acute care facility focus is on providing intensive care to a patient who is generally expected to recover or improve, and high technology is integral to the process. In LTCFs, the patient population may be very heterogeneous. Most LTCFs carry out plans of care that have already been established in acute care or evaluate chronic conditions. The LTCF is functionally the home for the resident, who is usually elderly and in declining health and will often stay for years, hence comfort, dignity, and rights are paramount. It is a low-technology setting. Residents are often transferred between the acute care and the LTC setting, adding an additional dynamic to transmission and acquisition of HAIs. Application of hospital infection control guidelines to the LTCF is often unrealistic in view of the differences noted above and the different infection control resources. Standards and guidelines specific to the LTCF setting are now commonly found. The problem of developing guidelines applicable to all LTCFs is compounded by the varying levels of nursing intensity (eg, skilled nursing facility vs assisted living), LTCF size, and access to physician input and diagnostic testing. This position paper provides basic infection control recommendations that could be widely applied to LTCFs with the expectation of minimizing HAIs in LTC. The efficacy of these measures in the LTCF, in most cases, is not proven by prospective controlled studies but is based on infection control logic, adaptation of hospital experience, LTCF surveys, Centers for Disease Control and Prevention (CDC) and other guidelines containing specific recommendations for LTCFs, and field experience. Every effort will be made to address the unique concerns of LTCFs. Because facilities differ, the infection risk factors specific to the resident population, the nature of the facility, and the resources available should dictate the scope and focus of the infection control program. In a number of instances, specific hospital-oriented guidelines have been published and are referenced (eg, guidelines for prevention of intravascular (IV) device-associated infection). These guidelines are relevant, at least in part, to the LTC setting but may be adapted depending on facility size, resources, resident acuity, local regulations, local infection control issues, etc. Reworking those sources to a form applicable to all LTCFs is beyond the scope of this guideline. Any discussion of infection control issues must be made in the context of the LTCF as a community. The LTCF is a home for residents, a home in which they usually reside for months or years; comfort and infection control principles must both be addressed.
