Abstract
Nursing homes (NH) residents with COVID-19 can either be tested because of presence of core symptoms (S-based) or because of transmission prevention (TP-based). The investigated study sample included all NH residents who underwent SARS-CoV-2 RT-PCR testing between March 16, 2020 and May 31, 2020 (n = 380). Clinical symptoms, temperature, and oxygen saturation were extracted from medical records, 7 days before to 14 days after testing. COVID-19 was confirmed in 81 (21%) residents; 36 (44%) S-based and 45 (56%) TP-based: 45. Cycle threshold (CT) values did not differ between the groups. In the 7 days prior to the test falling (32%), somnolence (25%) and fatigue (21%) occurred in both groups. Two days before the test, we observed a stronger decrease in oxygen saturation and an increase in temperature for the S-based group compared to the T-based group that remained up to 10 days after testing. Residents within the S-based group were 2.5 times more likely to increased mortality within 30 days than residents in the TP-based group (HR, 2.56; 95% 1.3–5.2). Although, 73% of the T-based group did eventually develop core symptoms. Thus, attention to falling and daily measures of temperature and oxygen saturation can contribute to earlier detection.

Abstract
Sepsis is a form of life-threatening organ dysfunction caused by dysregulated host responses to an infection that can be partly attributed to immune dysfunction. Although sepsis affects patients of all ages, elderly individuals display increased susceptibility and mortality. This is partly due to immunosenescence, a decline in normal immune system function associated with physiological aging that affects almost all cell types in the innate and adaptive immune systems. In elderly patients with sepsis, these alterations in immune cells such as endothelial cells, neutrophils, monocytes, macrophages, natural killer cells, dendritic cells, T lymphocytes, and B lymphocytes, are largely responsible for their poor prognosis and increased mortality. Here, we review recent studies investigating the events affecting both innate and adaptive immune cells in elderly mice and patients with sepsis, including alterations in their number, phenotype, and function, to shed light on possible new therapeutic strategies.

Abstract
BACKGROUND AND AIMS To examine antimicrobial resistance of commonly isolated pathogens in elderly hospitalized patients. METHODS Data regarding all clinically significant isolates from blood and urine cultures of patients admitted to a multilevel geriatric hospital during March 2015 to April 2016 were collected. Antimicrobial susceptibility testing was performed according to Clinical and Laboratory Standard Institute guidelines. RESULTS Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae were the most common isolates, with proportions of extended spectrum beta-lactamase positivity of 60, 40, and 61% respectively. Adjusted logistic regression models indicated that resistance of Escherichia coli to ceftriaxone [odds ratio (OR) 2.8, 95% confidence interval (CI) 1.5-5.1], ceftazidime (OR 2.8, 95% CI 1.5-5.1), ciprofloxacin (OR 2.2, 95% CI 1.2-4.0), amoxicillin/clavulanic acid (OR 2.3, 95% CI 1.2-4.3), and trimethoprim/sulfamethoxazole (OR 2.4, 95% CI 1.4-4.3) was significantly higher in skilled nursing wards than in acute geriatric wards. Resistance of Proteus mirabilis to ceftriaxone (OR 3.1, 95% CI 1.5-6.4) and Klebsiella pneumoniae to ciprofloxacin (OR 3.2, 95% CI 1.3-7.9) was significantly higher in skilled nursing wards than in acute wards. CONCLUSIONS AND DISCUSSION Antimicrobial resistance was found to be high in a multilevel geriatric hospital, especially in skilled nursing wards. These findings call for rethinking of the empirical antimicrobial therapy and of the efforts for prevention of nosocomial infection.

Abstract
The thermoregulatory functions may vary with age. Thermosensitivity is active in neonates and children; both heat production and heat loss effector mechanisms are functional but easily exhaustable. Proportional and lasting defense against thermal challenges is difficult, and both hypothermia and hyperthermia may easily develop. Febrile or hypothermic responses to infections or endotoxin can also develop, together with confusion. In small children febrile convulsions may be dangerous. In old age the resting body temperature may be lower than in young adults. Further, thermosensitivity decreases, the thresholds for activating skin vasomotor and evaporative responses or metabolism are shifted, and responses to thermal challenges are delayed or insufficient: both hypothermia and hyperthermia may develop easily. Infection-induced fevers are often limited or absent, or replaced by hypothermia. Various types of brain damage may induce special forms of hypothermia, hyperthermia, or severe fever. Impaired mental state often accompanies hypothermia and hyperthermia, and may occasionally be a dominant feature of infection (instead of the most commonly observed fever). Aging brings about a turning point in women's life: the menopause. The well-known influence of regular hormonal cycles on the thermoregulation of a woman of fertile age gives way to menopausal hot flushes caused by estrogen withdrawal. Not all details of this thermoregulatory anomaly are fully understood yet.

Abstract
AIM Febrile residents in long-term care facilities (LTCF) might be inadequately evaluated by caregivers. The present study aimed to examine the factors associated with inadequacy of initial fever evaluations by caregivers at night in LTCF. METHODS We carried out a cross-sectional study among a convenience sample of caregivers employed at 11 LTCF in Japan using a vignette-based questionnaire. The respondents were randomly assigned to one of two scenarios describing a mild or severe febrile episode in an LTCF resident at night. The respondents' thinking patterns were classified based on influential factors in their fever evaluation. Associations between adequacy of evaluation and respondents' characteristics were evaluated using generalized linear mixed models. RESULTS A total of 34% of fever evaluations among caregivers were considered to be inadequate regarding the necessity for examination by a physician, due in most cases to underestimating the severity of the fever. Respondents' thinking patterns in fever evaluation were significantly associated with the adequacy of the evaluation. Caregivers who placed particular importance on the preferences of residents and families versus other factors including the resident's febrile condition, were more likely to make an inadequate evaluation than those who did not. CONCLUSIONS Our findings here suggest that eagerness to comply with residents' preference in fever evaluation could prompt caregivers not to call for an appropriate diagnostic procedure.

Abstract
Healthcare-associated infections not only affect patients in acute care hospitals but also patients in need of long-term care. As the elderly are generally most affected, the demographic change in Germany faces a range of increasing challenges in the field of infection control. The ageing process itself is accompanied by several physiological and pathological changes which may result in an increase in the risk of infectious diseases. Elderly living in long-term care facilities (LTCFs) may in addition be exposed to further risks due to their everyday life in a community, nursing care and the, to some extent, inappropriate use of antibiotics. Bacteria that have become resistant to commonly used antimicrobial agents are meanwhile prevalent in nursing homes. Caregivers often feel left alone when facing the task of achieving a balance between the need for a comfortable familiar environment and the application of infection control measures according to a resolute prevention strategy. This review aims to give an overview about the characteristics of infections among the elderly, especially with respect to long-term care.

Abstract
Hospital admissions from nursing homes have not previously been investigated in Norway. During 12 months all hospital admissions (acute and elective) from 32 nursing homes in Bergen were recorded via the Norwegian ambulance register. The principal diagnosis made during the stay, length of stay, and the ward were sourced from the hospital's data register and data were merged. Altogether 1,311 hospital admissions were recorded during the 12 months. Admissions from nursing homes made up 6.1% of the total number of admissions to medical wards, while for surgical wards they made up 3.8%. Infections, fractures, cardiovascular and gastri-related diagnoses represented the most frequent admission diagnoses. Infections accounted for 25.0% of admissions, including 51.0% pneumonias. Of all the admissions, fractures were the cause in 10.2%. Of all fractures, hip fractures represented 71.7. The admission rate increased as the proportion of short-term beds increased, and at nursing homes with short-term beds, admissions increased with increasing physician coverage. Potential reductions in hospitalizations for infections from nursing homes may play a role to reduce pressure on medical departments as may fracture prevention. Solely increasing physician coverage in nursing homes will probably not reduce the number of hospitalizations.

Abstract
Koorts wordt bij niet-immuungecompromitteerde volwassenen in de eerste lijn zonder recent verblijf in het buitenland meestal veroorzaakt door een luchtweginfectie. Bij ouderen vormen urineweginfecties een relatief frequente oorzaak van koorts. Bij ontbreken van richtinggevende voorgeschiedenis, klachten of verschijnselen volstaat men in eerste instantie met lichamelijk onderzoek van KNO-gebied en longen. Bij negatieve bevindingen volgt urineonderzoek. Wanneer geen afwijkingen gevonden worden, gaat men uit van een onschuldige virale oorzaak. Bij een ernstig zieke indruk of verminderd bewustzijn is het lichamelijk onderzoek allereerst gericht op eventuele stoornissen in de vitale functies, omdat deze onmiddellijke therapeutische implicaties hebben. Als de koorts een week aanhoudt of eerder bij verandering van het beeld, dient een uitgebreide anamnese en algemeen lichamelijk onderzoek plaats te vinden om diagnostische aanknopingspunten op te sporen. Ook kan de arts dan aanvullend onderzoek laten verrichten: in eerste instantie bloed-, urine- en fecesonderzoek en een X-thorax, eventueel gevolgd door X-sinussen en een mantouxreactie. Medicatie wordt zoveel mogelijk gestaakt om een allergie aan te tonen of uit te sluiten. Na enkele dagen herhaalt men anamnese en lichamelijk onderzoek. Twee weken onbegrepen koorts is reden voor verdere (poli)klinische evaluatie. Concrete aanwijzingen op grond van steeds herhaalde anamnese en lichamelijk onderzoek zijn richtinggevend voor de inzet van complex aanvullend onderzoek. Dit bestaat onder meer uit bloedkweken, uitgebreider bloedonderzoek, leverbiopsie, beenmergpunctie en CT-scan buik en thorax. Bij patiënten ouder dan 55 jaar met koorts en een verhoogde bezinking is een biopsie van de arteria temporalis zinvol.

Abstract
Introduction. Infectious diseases may present with atypical presentations in the geriatric patients. While fever is an important finding of infections, it may also be a sign of noninfectious etiology. Methods. Geriatric patients who were hospitalized for acute fever in our infectious diseases unit were included. Acute fever was defined as presentation within the first week of fever above 37.3°C. Results. 185 patients were included (82 males and 103 females). Mean age was 69.7 ± 7.5 years. The cause of fever was an infectious disease in 135 and noninfectious disease in 32 and unknown in 18 of the patients. The most common infectious etiologies were respiratory tract infections (n = 46), urinary tract infections (n = 26), and skin and soft tissue infections (n = 23). Noninfectious causes of fever were rheumatic diseases (n = 8), solid tumors (n = 7), hematological diseases (n = 10), and vasculitis (n = 7). A noninfectious cause of fever was present in one patient with no underlying diseases and in 31 of 130 patients with underlying diseases. Conclusion. Geriatric patients with no underlying diseases generally had infectious causes of fever while noninfectious causes were responsible from fever in an important proportion of patients with underlying diseases.

Abstract
Residents of long‐term care facilities (LTCFs) are at great risk for infection. Most residents are older and have multiple comorbidities that complicate recognition of infection; for example, typically defined fever is absent in more than one‐half of LTCF residents with serious infection. Furthermore, LTCFs often do not have the on‐site equipment or personnel to evaluate suspected infection in the fashion typically performed in acute care hospitals. In recognition of the differences between LTCFs and hospitals with regard to hosts and resources present, the Infectious Diseases Society of America first provided guidelines for evaluation of fever and infection in LTCF residents in 2000. The guideline presented here represents the second edition, updated by data generated over the intervening 8 years. It focuses on the typical elderly person institutionalized with multiple chronic comorbidities and functional disabilities (e.g., a nursing home resident). Specific topic reviews and recommendations are provided with regard to what resources are typically available to evaluate suspected infection, what symptoms and signs suggest infection in a resident of an LTCF, who should initially evaluate the resident with suspected infection, what clinical evaluation should be performed, how LTCF staff can effectively communicate about possible infection with clinicians, and what laboratory tests should be ordered. Finally, a general outline of how a suspected outbreak of a specific infectious disease should be investigated in an LTCF is provided.

Abstract
AIM The goal of this study was to determine whether the factors associated with delirium varied according to the severity of the delirium experienced by the older patients. BACKGROUND Delirium among older patients is prevalent and leads to numerous detrimental effects. The negative consequences of delirium are worse among older adults with severe delirium compared with patients with mild delirium. There has been no study identifying those factors associated with delirium severity among long-term care older patients newly admitted to an acute care hospital. DESIGN This is a descriptive study. METHODS This is a secondary analysis study of institutionalized older patients newly admitted to an acute care hospital (n = 104). Upon admission, patients were screened for delirium with the Confusion Assessment Method and severity of delirium symptoms were determined by using the Delirium Index. RESULTS Of the 71 delirious older patients, 32 (45.1%) had moderate-severe delirium while 39 (54.9%) presented mild delirium. In univariate analyses, a significant positive relationship was observed between the level of prior cognitive impairment and the severity of delirium (p = 0.0058). Low mini-mental state examination (MMSE) scores (p < 0.0001), the presence of severe illness at the time of hospitalization (p = 0.0016) and low functional autonomy (BI: p = 0.0017; instrumental activities of daily living: p = 0.0003) were significantly associated with moderate-severe delirium. Older patients suffering from mild delirium used significantly more drugs (p = 0.0056), notably narcotics (p = 0.0017), than those with moderate-severe delirium. Results from the stepwise regression indicated that MMSE score at admission and narcotic medication use are the factors most strongly associated with the severity of delirium symptoms. CONCLUSIONS This present study indicates that factors associated with moderate-severe delirium are different from those associated with mild delirium. Given the result concerning the role of narcotics, future studies should evaluate the role of pain management in the context of delirium severity. RELEVANCE TO CLINICAL PRACTICE As moderate-severe delirium is associated with poorer outcomes than is mild delirium, early risk factor identification for moderate-severe delirium by nurses may prove to be of value in preventing further deterioration of those older patients afflicted with delirium.

Abstract
OBJECTIVES To evaluate the effect of vitamin and mineral supplementation on infections in an elderly institutionalized population. DESIGN Eighteen-month, randomized, placebo-controlled trial. SETTING Twenty-one long-term care facilities. PARTICIPANTS Seven hundred sixty-three subjects from 21 long-term care facilities. INTERVENTION Participants were randomized to receive one multivitamin and mineral supplementation daily or placebo. MEASUREMENTS The primary outcome was number of infections per subject. Secondary outcomes were antibiotic use and hospitalization rates. Infection control surveillance was conducted over 18 months using standardized criteria. RESULTS Outcome data from 748 subjects, mean age 85, were included in the intention-to-treat analysis. Using univariate analyses, there was no difference in infectious episodes between the supplemented and placebo groups (3.5 infections per 1,000 resident-days vs 3.8 infections per 1,000 resident-days, odds ratio (OR)=0.92, 95% confidence interval (CI)=0.82-1.03, P=.12). There was a reduction in antibiotic usage in the supplementation group, but this was not significant in the multivariate model. There was no difference in the number of hospital visits. In the multivariate analysis, the effect of multivitamin use on total number of infections was not significant (OR=0.77, 95% CI=0.54-1.1). Subjects without dementia had a greater rate of infections than those with dementia (OR=1.44, 95% CI=1.19-1.76). In post hoc subgroup analysis, subjects without dementia who received supplementation had a significantly lower rate of infections than those who received placebo (relative risk=0.81, 95% CI=0.66-0.99). CONCLUSION Overall, multivitamin and mineral supplementation does not have a significant effect on the incidence of infections in institutionalized seniors, although the subgroup of residents in long-term care without dementia may benefit from supplementation. Further research is needed to determine its effect in high-risk subgroups within the nursing home population.

Abstract
Hypoglycemia is common in elderly community dwelling patients and may accompany episodes of acute infection. We analyzed the interrelations of clinical variables with infection-related hypoglycemia (IRH) and its outcome in institutionalized demented elderly patients, with and without diabetes mellitus (DM). This is a retrospective cohort study involving residents of a large long term-care facility. We measured demographic, clinical, functional, nutritional and cognitive data as well as blood counts and chemistry analysis. We identified 65 elderly patients with IRH and compared data of 33 diabetic patients with 32 nondiabetic patients. Mean age of patients was 77.7 years and mean Mini-Mental score of 1.8. Diabetic patients were younger, more cognitively impaired, had a lower functional score (nonsignificant differences), but presented with more comorbidities, compared with nondiabetics (p=0.004). Mean blood glucose levels in diabetics and nondiabetics were 53.2 and 54.3 mg/dl, respectively. Only 22% of the patients showed clinical signs indicating hypoglycemia. Multivariate analysis showed that, in groups, comorbidity and functional status, creatinine, albumin, C-reactive protein (CRP) and total cholesterol were all associated with IRH. During a 6 months period, 58% (38/65) of the patients died, out of whom 47% (18/38) died within one month following the documentation of IRH. There were no statistically significant differences in short and late mortality rates between patients with and without DM. we conclude that asymptomatic IRH in institutionalized demented elderly is frequently associated with common respiratory and urinary infections, in both diabetic and nondiabetic patients. IRH seems to indicate a poor general health status rather than being the cause of death. Blood glucose needs to be screened in this population during common infections, also in nondiabetics, to identify patients at high risk.

Abstract
As life expectancy continues to rise, the number of geriatric patients will increase and the percentages of geriatric patients seen in the emergency department will reflect those numbers. Emergency physicians are responsible for making immediate diagnoses and initiating expeditious treatment. Infectious diseases in the elderly are more prevalent, challenging to diagnose, and are associated with greater morbidity and mortality than with the younger patient population.

Abstract
Elderly patients are at increased risk for developing infections and fever. We aimed to investigate the incidence, causes and outcome of hypernatemia and hyponatremia among elderly long-term care patients with febrile illness. This is a prospective study conducted in a 110 beds, nursing department for dependent elderly in geriatric long-term care facility during 20 months period. Changes in plasma sodium concentrations were found in 48% (132/270) of the febrile illness: during the acute illness in 38% (102/270) of the events and during the follow-up period after acute febrile event, in 30% (59/198) of the events. Upper respiratory tract, bronchial, lung, and urinary tract infections were the most common causes for the fever. Hypernatremia was more prevalent on acute febrile illness (63%). Hyponatremia was more common before the febrile illness (10%) and during the follow-up period (69%). The most common causes of hypernatremia were inadequate hydration or correction (57%) and continuous diuretic treatment (38%). The most common causes of hyponatremia were: Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) (38%), incorrect hydration (19%), and continuous diuretic treatment (30%). During the study, 60% (28/47) of the patients died, and hypernatremia was detected in 82% (20/28). Disturbances in sodium concentrations were predictors of bad outcomes, related to the underlying diseases burden, and were not related to the magnitude of the changes in plasma sodium, time of its development, advanced age, gender and coexisting changes in plasma potassium level.

Abstract
BACKGROUND AND AIMS The nature of adverse clinical events (ACE) during duty hours (16:00-08:00 and holidays), as well as the way they are addressed by duty physicians (DP) in a nursing home (NH) are the subject of this study. METHODS Data, including medical details concerning ACEs and the resultant referrals to hospital, were collected prospectively during 183 consecutive days in a 90-bed NH. RESULTS Ninety-six residents experienced 370 ACEs, representing an average of one for every 44.5 patient days. The highest rate of events was during evening hours (18:00-21:00). The most prevalent ACE was fever (32%). Most cases (53%) were treated by the DPs on site. No intervention was needed in 19% of cases, whereas 28% of ACEs (104 cases) were referred to the Emergency Room (ER) of a general hospital. Sixty-six percent of these were actually admitted. The rate of ER referral of residents was one for every 158 patient days. About 40% of the referred patients had been discharged from hospital the previous week. High fever was the commonest cause for referral: 47%. During the working hours of the study period, the rate of referral by the staff physician was only 1 for every 915 patient days. Only 17% of these had high fever. CONCLUSIONS Evening rounds by staff physicians, strengthening of working relations with hospital physicians, as well as fostering intravenous treatment in NHs, are suggested as means for reducing hospital transfers. A standardized method for the reporting of ACEs and referrals to hospitals should be adopted in order to facilitate comparisons between NHs and to evaluate its use as a quality indicator.

Abstract
Pneumonia is a major medical problem in the very old. The increased frequency and severity of pneumonia in the elderly is largely explained by the ageing of organ systems (in particular the respiratory tract, immune system, and digestive tract) and the presence of comorbidities due to age-associated diseases. The most striking characteristic of pneumonia in the very old is its clinical presentation: falls and confusion are frequently encountered, while classic symptoms of pneumonia are often absent. Community-acquired pneumonia (CAP) and nursing-home acquired pneumonia (NHAP) have to be distinguished. Although there are no fundamental differences in pathophysiology and microbiology of the two entities, NHAP tends to be much more severe, because milder cases are not referred to the hospital, and residents of nursing homes often suffer from dementia, multiple comorbidities, and decreased functional status. The immune response decays with age, yet pneumococcal and influenza vaccines have their place for the prevention of pneumonia in the very old. Pneumonia in older individuals without terminal disease has to be distinguished from end-of-life pneumonia. In the latter setting, the attributable mortality of pneumonia is low and antibiotics have little effect on life expectancy and should be used only if they provide the best means to alleviate suffering. In this review, we focus on recent publications relative to CAP and NHAP in the very old, and discuss predisposing factors, microorganisms, diagnostic procedures, specific aspects of treatment, prevention, and ethical issues concerning end-of-life pneumonia.

Abstract
Delirium has been recognized for the last 3 millennia and is the most common complication found in hospitalized patients aged 65 and older in the United States. However, critical basic science and clinical research did not progress until the DSM III criteria clearly defined delirium 20 years ago. The term delirium then replaced many nonspecific entities, such as acute confusion state, acute brain syndrome, metabolic encephalopathy, and toxic psychosis. This review discusses the epidemiology, risk factors, interventions, causes, management, and outcomes of delirium. The pathophysiology of delirium has the potential to radically alter our management of delirium and is a controversial area of research.

Abstract
Throughout the history of mankind, infectious diseases have remained a major cause of death and disability. Although industrialized nations, such as the United States, have experienced significant reductions in infection-related mortality and morbidity since the beginning of the "antibiotic era," death and complications from infectious diseases remain a serious problem for older persons. Pneumonia is the major infection-related cause of death in older persons, and urinary tract infection is the most common bacterial infection seen in geriatric patients. Other serious and common infections in older people include intra-abdominal sepsis, bacterial meningitis, infective endocarditis, infected pressure ulcers, septic arthritis, tuberculosis, and herpes zoster. As a consequence, frequent prescribing of antibiotics for older patients is common practice. The large volume of antibiotics prescribed has contributed to the emergence of highly resistant pathogens among geriatric patients, including methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, vancomycin-resistant enterococci, and multiple-drug-resistant gram-negative bacilli. Unless preventive strategies coupled with newer drug development are established soon, eventually clinicians will be encountering infections caused by highly resistant pathogens for which no effective antibiotics will be available. Clinicians could then be experiencing the same frustrations of not being able to treat infections effectively as were seen in the "pre-antibiotic era."

Abstract
PURPOSE In the geriatric units of the University Hospital of Saint-Etienne, 129 cases of fever (38 degrees C or more) were recorded prospectively during the 1995-1996 winter period in a population of 503 hospitalised patients (25.6%), and were investigated for the detection of a viral aetiology. METHODS In febrile patients, a standard form was used to record clinical and biological parameters, including the results of investigations for respiratory viruses from a nasal swab and dual serum specimens. RESULTS A clinical or radiological respiratory infection was found in 69 cases (53.5% of all cases of fever), including 14 respiratory syncytial virus (RSV) infections. In comparison to nonviral respiratory infections, the RSV infections were characterised by the prevalence of anorexia (57% vs 20%, P < 0.05) and rhinorrhea (64% vs 5%, P < 0.01). No influenza infection was recorded despite the concomitant circulation of influenza virus in the community. A nosocomial outbreak of RSV infection (nine cases, attack rate of 18.7%) was identified in a long-stay care unit. CONCLUSION This study illustrates the high prevalence (10.9%) of RSV infections in elderly patients with fever during this season and the importance of hygienic measures to control the spread of nosocomial outbreaks.

Abstract
The elderly population (i.e., persons aged > or = 65 years) in the United States is rapidly expanding and will nearly double in number over the next 30 years. It is estimated that >40% of persons aged > or = 65 years will require care in a long-term care facility (LTCF), such as a skilled nursing facility (SNF), at some point during their lifetime. For the most part, residents of LTCFs are very old and have age-related immunologic changes, chronic cognitive and/or physical impairments, and diseases that alter host resistance; therefore, they are highly susceptible to infections and their complications. The diagnosis of infections in residents of LTCFs is often difficult because LTCFs differ from acute-care facilities in their goals of care, staffing ratios, types of primary care providers, availability of laboratory tests, and criteria for infections. Consequently, guidelines and standards of practice used for diagnosis of infections in patients in acute-care facilities may not be applicable nor appropriate for residents in LTCFs. Moreover, the clinical manifestations of diseases and infections are often subtle, atypical, or nonexistent in the very old. Fever may be low or absent in LTCF residents with infection. The initial evaluation of an LTCF resident suspected of an infection may not be done by a physician. Although nurses commonly perform initial assessments for infection in residents of LTCFs, further studies are needed to determine the appropriateness and validity of this practice. Provided there are no directives (advance or current by resident or caregiver) limiting diagnostic or therapeutic interventions, all residents of LTCFs with suspected symptomatic infection should have appropriate diagnostic laboratory studies done promptly, and the findings should be discussed with the primary care clinician (see Recommendations). The most common infections among LTCF residents are urinary tract infections, respiratory infections, skin or soft tissue infections, and gastroenteritis. Decisions concerning possible transfer of an LTCF resident to an acute-care facility are best expressed through an advance directive or, when not available, through transfer policies developed by the LTCF. In general, LTCF residents have been transferred to an acute-care facility when any of the following conditions exist: (1) the resident is clinically unstable and the resident or family goals indicate aggressive interventions should be initiated, (2) critical diagnostic tests are not available in the LTCF, (3) necessary therapy or the mode of administration of therapy (frequency or monitoring) are beyond the capacity of the LTCF, (4) comfort measures cannot be assured in the LTCF, and (5) specific infection-control measures are not available in the LTCF.

Abstract
Point prevalence studies of hospital-acquired infections among the elderly in 65-70 long-term care facilities (LTCF) were carried out once a year over a three-year period in Oslo city, Norway. They showed an overall rate of 6.5% of hospital-acquired infections among 13 762 residents. The infection rate was approximately the same as in hospitals and twice as high as among hospitalized long-term psychiatric patients. Residents who had received surgical treatment within the previous three months had a high rate of postoperative infections, especially wound infections (14.8%). During the study period, the LTCFs were found to be understaffed and overcrowded. They had few private rooms, a lack of bathrooms and toilets, no isolation facilities and deficient ventilation systems. The economic consequences of hospital-acquired infections in these LTCFs were extra costs in medical and nursing care and antibacterial treatment of 157 500 Nkr/day (22500 USD). There would be a substantial cost-benefit in effective preventive measures against hospital-acquired infections in long-term care institutions.

Abstract
Clinicians involved in caring for institutionalized elderly frequently must treat common infections endemic to the setting. Numerous factors specific to these patients make accurate diagnosis and management more difficult than in healthy ambulatory adults. Three infections are commonly encountered in residents of long-term care facilities: bacterial pneumonia, urinary tract infections, and skin and soft tissue infections. More antimicrobial agents are available now than ever before; therefore, judicious administration of drugs and familiarity with current treatment recommendations are imperative.

Abstract
Nursing Home-Acquired Pneumonia is a significant infection that is often seen in the long-term care setting. It is associated with substantial morbidity, healthcare expenditure, and mortality rates as high as 44%. Uniform diagnosis and therapeutic strategies have not been specifically established for pneumonia in the nursing home setting. This paper will update the long-term care provider with the unique features and challenges of pneumonia in this setting and review the approaches to the diagnosis and treatment of this important illness. The discussion will conclude with details regarding overall prevention of nursing home-acquired pneumonia and the critical role played by the nursing home medical director in this process.

Abstract
OBJECTIVE To describe outbreaks of infection caused by Legionella sainthelensi occurring in older residents of two nursing homes and to determine risk factors for the development of infection. DESIGN Descriptive epidemiology and a case-control study. SETTING Two nursing homes (140 beds and 254 beds in nursing homes A and B, respectively) located in southern Ontario, Canada, experiencing outbreaks of respiratory tract infection in July and August 1994. SUBJECTS Case-residents of the two nursing homes who met clinical and laboratory criteria for Legionella infection. Control-residents were defined as those who were in the homes during the outbreaks and were asymptomatic. MEASUREMENTS Active surveillance was conducted in both nursing homes to identify symptomatic residents. Residents with fever or respiratory tract symptoms had nasopharyngeal swabs taken for viral antigen detection and culture, urine for Legionella antigen detection, and acute and convalescent serology for viruses, Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella. Chest X-rays were performed, and an attempt was made to obtain blood and sputum cultures. Water samples from shower heads, faucets, and air conditioning units were collected for Legionella culture and polymerase chain reaction (PCR) assay. A case-control study was done to assess possible risk factors for legionellosis. RESULTS Twenty-nine cases -- 17 in nursing home A; 12 in nursing home B - were identified. Four (14%) case-residents had documented pneumonia and four case-residents died. Univariate analysis revealed that a history of stroke (odds ratio (OR) 2.3 (95% CI, 1.0-5.3)), eating pureed food (OR 4.6 (95% CI, 1.6-12.7)), and having fluids administered with medication (OR 2.5 (95% CI, 1.0-5.9)) were significant risk factors. Cases were less likely to wear dentures (OR .4 (95% CI, .2-.9)) or to eat solid food (OR .3, (95% CI, .1-.6)). Only eating pureed food remained significant in a multivariable analysis (OR 4.6 (95% CI, 1.6-13.0, P = .01)). CONCLUSION This report describes outbreaks of legionellosis in two nursing homes, representing the first reported outbreaks of infection caused by Legionella sainthelensi. The association with illness of dietary characteristics indicative of swallowing disorders suggests that aspiration was the most likely mode of infection. The diagnosis of legionellosis should be considered during outbreaks of respiratory infection in nursing homes.

Abstract
Increasing numbers of elderly people are being treated in hospitals and are at particular risk of acquiring infections. The incidence, risk factors and types of hospital-acquired infection (HAI) in the elderly are reviewed. Special reference is made to urinary tract infections, respiratory tract infections, gastrointestinal infections including Clostridium difficile, bacteraemia, skin and soft tissue infections and infections with antibiotic-resistant organisms.

Abstract
A randomized, double-blind, placebo-controlled clinical trial was conducted to determine the effects of a low-dose (< 2 times the Recommended Dietary Allowance) micronutrient supplement containing trace minerals (zinc and selenium) and/or vitamins/provitamins (vitamin C, alpha-tocopherol, and beta-carotene) on the incidence of respiratory and urogenital infections in institutionalized elderly. After 2 years, there was a significant decrease in the mean number of infections in elders given trace elements (p < 0.01) but not vitamins.
