No single virus has the health impact of influenza. Influenza has remained epidemiologically important because it escapes host immune pressure through antigenic variation, is highly contagious, and can cause pneumonia and death in the most susceptible hosts. Viral transmission is most efficient where contact between susceptible hosts is greatest. For humans, this includes institutional settings such as daycare centers, schools, hospitals, and long-term care facilities.Of the three types of influenza, influenza C is relatively nonvirulent. Influenza B is most virulent in children; its antigenic stability presumably allows the adult population to benefit from acquired immunity. Influenza A is virulent in people of all ages, especially in those at the extremes of age or with immunocompromising disease; the attack rate in persons over 70 years of age is four times that of adults under 40 years of age. A major factor accounting for recurrent influenza A epidemics is change in the virus (antigenic drift and shift) that renders the vaccine less efficacious. Influenza epidemics cost billions of dollars and result in thousands of deaths annually. This discussion will focus on the prevention and treatment of influenza A in the long-term care facility.

Influenza Outbreaks

Influenza is a major cause of illness and death in residents of long term care facilities for the elderly, in part because residents' age and underlying illness increase the risk of serious complications, and in part because institutional living increases the risk of influenza outbreaks. The administration of antiviral medications active against influenza to persons exposed to influenza has been shown to protect them effectively from illness, and mass antiviral prophylaxis of residents is an effective means of terminating influenza A outbreaks in long term care facilities. The only antiviral currently licensed in Canada for influenza prophylaxis is amantadine, a medication active against influenza A but not influenza B. The National Advisory Committee on Immunization recommends that amantadine prophylaxis be offered to residents when influenza A outbreaks occur in long term care facilities. However, there remain a number of unanswered questions about how best to use amantadine for controlling influenza A outbreaks in long term care facilities. In addition, two members of a new class of antivirals called neuraminidase inhibitors have recently been licensed in Canada for the treatment of influenza, and are effective in prophylaxis. Issues in the use of amantadine in the control of outbreaks of influenza A in long term care facilities for the elderly are reviewed, and the potential uses of neuraminidase inhibitors in this setting are discussed.

ObjectiveTo assess the feasibility of conducting respiratory virus surveillance for residents of long term care facilities (LTCF) using simple nasal swab specimens and to describe the virology of acute respiratory infections (ARI) in LCTFs.IntroductionAlthough residents of LTCFs have high morbidity and mortality associated with ARIs, there is very limited information on the virology of ARI in LTCFs.[1,2] Moreover, most virological testing of LCTF residents is reactive and is triggered by a resident meeting selected surveillance criteria. We report on incidental findings from a prospective trial of introducing rapid influenza diagnostic testing (RIDT) in ten Wisconsin LTCFs over a two-year period with an approach of testing any resident with ARI.MethodsAny resident with new onset of respiratory symptoms consistent with ARI had a nasal swab specimen collected for RIDT by nursing staff. Following processing for RIDT (Quidel Sofia Influenza A+B FIA), the residual swab was placed into viral transport medium and forwarded to the Wisconsin State Laboratory of Hygiene and tested for influenza using RT-PCR (IVD CDC Human Influenza Virus Real-Time RT-PCR Diagnostic Panel), and for 17 viruses (Luminex NxTAG Respiratory Pathogen Panel [RPP]). The numbers of viruses in each of 7 categories [influenza A (FluA ), influenza B (FluB), coronaviruses (COR), human metapneumovirus (hMPV), parainfluenza (PARA), respiratory syncytial virus (RSV) and rhinovirus/enterovirus (R/E)], across the two years were compared using chi-square.ResultsTotals of 164 and 190 specimens were submitted during 2016-2017 and 2017-2018, respectively. RPP identified viruses in 56.2% of specimens, with no difference in capture rate between years (55.5% vs. 56.8%). Influenza A (21.5%), influenza B (16.5%), RSV (19.0%) and hMPV (16.5%) accounted for 73.5% of all detections, while coronaviruses (15.5%), rhino/enteroviruses (8.5%) and parainfluenza (2.5%) were less common. Specific distribution of viruses varied significantly across the two years (Table: X2=48.1, df=6; p<0.001).ConclusionsSurveillance in LTCFs using nasal swabs collected for RIDT is highly feasible and yields virus identification rates similar to those obtained in clinical surveillance of ARI with collection of nasopharyngeal specimens by clinicians and those obtained in a school-based surveillance project of ARI with collection of combined nasal and oropharyngeal specimens collected by trained research assistants. Significant differences in virus composition occurred across the two study years. RSV varied little between years while hMPV demonstrated wide variation. Simple approaches to surveillance may provide a more comprehensive assessment of respiratory viruses in LTCF settings.References(1) Uršič T, Gorišek Miksić N, Lusa L, Strle F, Petrovec M.

Influenza Outbreaks

AbstractInfluenza is a frequent cause of epidemic and endemic respiratory illness in long-term-care facilities (LTCFs), resulting in considerable morbidity and mortality. Detection of influenza outbreaks in this setting can be difficult, because the clinical presentation in older adults is atypical and other pathogens also cause influenza-like illness (ILI) during the influenza season. Use of the standard case definition for influenza has not been effective in detecting episodes in residents of LTCFs. Alternative case-definitions that reflect the atypical presentation of influenza in this population have been recommended but not validated. The use of rapid tests for the detection of influenza in conjunction with more sensitive case definitions of ILI may lead to the earlier detection of influenza outbreaks in LTCFs, earlier initiation of infection control measures, and reduction in transmission.The definition of outbreak, eg, the number of episodes of ILI or episodes of confirmed influenza A that would result in the initiation of antiviral chemoprophylaxis, remains controversial in this setting. The use of newer antivirals could limit the side effects seen in older adults in LTCFs. However, annual vaccination of residents and staff remains the most effective way to prevent the introduction of influenza A or influenza B into LTCFs. In addition, vaccination of LTCF residents reduces rates of illness and pneumonia due to influenza, as well as cardiopulmonary exacerbation, hospitalization, and death.

Abstract A consequence of the strict visitor restrictions implemented by many Long-term Care Facilities (LTCFs), during the COVID-19 pandemic, was the exacerbation of loneliness and social isolation felt by older adult residents. While there had been a shift by some persons to utilize digital solutions to mitigate the effects of the imposed social isolation, many facilities did not have sufficient information regarding available solutions to implement institutional strategies to support social connectedness through digital solutions. To support our partners in evidence-based policy-making we conducted a scoping review to identify existing virtual technology solutions, apps, and platforms feasible to promote social connectedness among persons residing in a long-term care facility context during times of lockdown such as experienced during the COVID-19 pandemic. Initial identification of relevant literature involved a combination of keywords and subject headings searches within 5 databases (PubMed, CINAHL EBSCO, PsychINFO EBSCO, Embase OVIDSP, and Web of Science ISI). DistillerSR was used to screen, chart and summarize the data. There is growth in the availability of technologies focused on promoting health and well-being in later life for persons in long-term care facilities however a gap remains in widespread uptake. We will describe the breadth of technologies identified in this review and discuss how they vary in utility in smaller scale facilities common in rural areas. Of the technologies that can be used to mitigate the impacts of social isolation felt by long-term care residents, many “solutions” depend on stable highspeed internet, which remains a challenge in rural and northern areas.

Abstract Older adults from racial and ethnic minority groups face health inequities in long-term care facilities such as nursing homes and assisted living facilities just as they do in the United States as a whole. In spite of federal policy to support minority health and ensure the well-being of long-term care facility residents, disparities persist in residents’ quality of care and quality of life. This poster presents current federal policy in the United States to reduce racial and ethnic health disparities and to support long-term care facility residents’ health and well-being. It includes legislation enacted by the Patient Protection and Affordable Care Act of 2010 (ACA), regulations of the U.S. Department of Health and Human Services (DHHS) for health care facilities receiving Medicare or Medicare funds, and policies of the Long-term Care Ombudsman Program. Recommendations to address threats to or gaps in these policies include monitoring congressional efforts to revise portions of the ACA, revising DHHS requirements for long-term care facilities staff training and oversight, and amending requirements for the Long-term Care Ombudsman Program to mandate collection, analysis, and reporting of resident complaint data by race and ethnicity.

BACKGROUND: Pneumonia is a common reason for hospital admission, and the cost of treatment is primarily determined by length of stay (LOS).OBJECTIVES: To explore the changes to and determinants of hospital LOS for patients admitted for the treatment of community-acquired pneumonia over a decade of acute hospital downsizing.METHODS: Data were extracted from the database of Vancouver General Hospital, Vancouver, British Columbia, on patients admitted with community-acquired pneumonia (International Classification of Diseases, Ninth Revision, Clinical Modification codes 481.xx, 482.xx, 483.xx, 485.xx and 486.xx) from January 1, 1991 to March 31, 2001. The effects of sociodemographic factors, the specialty of the admitting physician (family practice versus specialist), admission from and/or discharge to a long-term care facility (nursing home) and year of admission, adjusted for comorbidity, illness severity measures and other potential confounders were examined. Longitudinal changes in these factors over the 10-year period were also investigated.RESULTS: The study population (n=2495) had a median age of 73 years, 53% were male and the median LOS was six days. Adjusted LOS was longer for women (10% increase, 95% CI 3 to 16), increasing age group (7% increase, 95% CI 4 to 10), admission under a family physician versus specialist (42% increase, 95% CI 32 to 52) and admission from home with subsequent discharge to a long-term care facility (75% increase, 95% CI 47 to 108). Adjusted hospital LOS decreased by an estimated 2% (95% CI 1 to 3) per annum. The mean age at admission and the proportion admitted from long-term care facilities both increased significantly over the decade (P<0.05).CONCLUSIONS: Results suggest that the management of hospitalized patients with pneumonia changed substantially between 1991 and 2001. The interface of long-term care facilities with acute care would be an important future area to explore potential efficiencies in caring for patients with pneumonia.

Long term care (LTC) facilities, also called nursing homes, are often ripe for conflicts which cause stress for residents, their families and staff. This article presents the results of a survey showing how nursing facility administrators in Harris County, Texas, managed conflict within their facilities and how a more positive approach was consistently reflected in how their facilities were rated in US government quality consumer ratings. The concept at the centre of this study, SOS-Semantics of Self in Conflict™, recognises that the degradation of standards due to conflict is not just an event in a nursing care facility. It is a process that is heavily influenced, and in some cases exacerbated, by the way in which facility administrators react to conflict. These reactions have important broader implications for the facility’s best practice retrospectively.
