ECRI Institute and Annals of Long-Term Care: Clinical Care and Aging (ALTC) have joined in collaboration to bring ALTC readers periodic articles on topics in risk management, quality assurance and performance improvement (QAPI), and safety for persons served throughout the aging services continuum. ECRI Institute is an independent nonprofit that researches the best approaches to improving health care.
Long-term care (LTC) facilities pose unique infection control risks to residents, as these facilities are comprised of shared living spaces, circulated air, high-touch surfaces, and equipment (eg, physical and occupational therapy equipment), and residents generally socialize freely with one another. They may have direct or indirect contact with visitors and staff as well. Residents may introduce infections into the facility when they are transferred from other care settings or home.1 Infections that commonly occur in LTC facilities2 can be found at Box 1.
Infections in LTC residents are associated with morbidity and mortality, hospital admissions and emergency department visits, antimicrobial use, and related costs. A 2000 review estimated that 25% to 50% of hospital admissions of LTC residents—or about 153,000 to 306,000 US hospital admissions annually—are due to infection. It also found that in LTC rates of death associated with infection range from 0.04 to 0.71 per 1000 resident-days. Thus, the researchers projected, 21,880 to 388,370 resident deaths associated with infection occur each year, with pneumonia being the leading cause of death.3 Figure 1 provides a visual representation of the incidence of common endemic infections per 1000 resident-days. However, as one expert notes, it is not always clear whether death is attributable to the infection or to underlying chronic disease.4
Despite the susceptibility of LTC residents to infection and the relatively high frequency of infections in these settings, improvements in infection prevention and control can make a difference.
Antimicrobial Use and Antibiotic Resistance
Multidrug-resistant organisms (MDROs) are a pressing concern in LTC. An estimated 12.7 antibiotic-resistant infections per 1000 long-term skilled nursing facility residents occur annually.5 Inappropriate antimicrobial use not only promotes the emergence of MDROs, it also raises the risk of Clostridium difficile infection, medication side effects, and adverse drug reactions.
In April 2014, the World Health Organization issued a report that found that in many parts of the world, drug resistance has reached “alarming” levels and that a “major gap in knowledge” exists regarding the current threat level of antibiotic resistance in common bacteria. The report stated that, “A post-antibiotic era—in which common infections and minor injuries can kill—far from being an apocalyptic fantasy, is instead a very real possibility for the 21st century.”6 The following year, the White House announced a 5-year plan to combat antibiotic resistance. Developed in response to an executive order, National Action Plan for Combating Antibiotic-Resistant Bacteria lists strengthening antibiotic stewardship programs in inpatient, outpatient, and LTC settings as a sub-objective.7
Indeed, studies show there is a need for improvement in antimicrobial use in LTC. In a literature review, the percentage of antibiotic orders in LTC facilities that were deemed appropriate ranged from only 49% to 62%.8 Another study found that even in residents with advanced dementia, most of whom had comfort as the primary goal of care, clinical criteria for antimicrobial initiation were present for only 44% of infections treated with antimicrobials. In addition, 48% of residents who were not colonized with an MDRO at baseline became colonized with an MDRO within a year.9
Coordination with other health care organizations is important when trying to optimize infection prevention strategies. The Centers for Disease Control and Prevention has called on health care organizations to work more closely together to stop the spread of antibiotic-resistant organisms. A 2015 report from the agency concluded that coordinated approaches to halt the spread of resistant organisms—for example, by implementing systems to alert receiving facilities when enhanced infection control is needed for transferred patients who are colonized or infected with resistant organisms—would have more impact than only programs based in individual facilities. Such approaches could avert an estimated 619,000 antibiotic-resistant, healthcare-associated infections over 5 years, the agency estimates.10 Box 2 provides recommended actions facilities can take to prevent infections.
Despite facilities’ best efforts at prevention, infectious disease outbreaks will still occur due to the nature of LTC settings, as mentioned previously. Outbreaks are common in LTC, but, according to the Infectious Diseases Society of America, routine review of surveillance data can help organizations promptly recognize potential outbreaks. After an outbreak has already occurred, research suggests that facilities take the initial steps provided in Box 3 to confirm and plan a response to an outbreak in their settings.11 According to an email from Christopher J Crnich, MD, MS, (April 20, 2012), the organization may also consider training frontline staff to institute isolation precautions based on observed signs and symptoms, if indicated, until a diagnosis is established.
In addition, the Society for Healthcare Epidemiologists of America/Association for Professionals in Infection Control and Epidemiology guideline “Infection Prevention and Control in the Long-Term Care Facility” recommends delineating authority for intervening during an outbreak. It suggests establishing a protocol for response that addresses authority for tasks such as relocating residents, restricting residents to their rooms, restricting visitors, obtaining cultures, instituting isolation, and administering treatment or prophylaxis. It also recommends obtaining consent for diagnostic and therapeutic outbreak measures on resident admission.2 Organizations should also address infection prevention and control in their emergency plans.
