Abstract
Fever can be due to infectious or noninfectious causes and results from the body's natural response to exogenous or endogenous pyrogens. Laboratory tests including complete blood count, differential blood count, C‑reactive protein, erythrocyte sedimentation rate and procalcitonin do not have sufficient sensitivity and specificity to definitively detect or rule out an infectious (bacterial, viral, parasitic) cause of fever. Blood cultures should be carried out when bacteremic or septic illnesses are suspected. Fever is not always present in infections and can be absent, especially in older and immunocompromised patients. If fever is suspected, core temperatures should be taken, e.g., rectally, orally or invasively. Depending on the clinical situation, infectious causes must be excluded as the most likely cause of an acutely occurring fever. The investigation of long-standing fever (fever of unknown origin, FUO) can be complex and some infectious diseases should first be ruled out, whereby a syndromic classification often helps to clarify the cause of the fever.

Abstract
Background Nursing care residents have high hospitalization rates. To address this, we established a unique virtual geriatric unit that has developed a program aimed at providing support to nursing homes. Aims We aimed to evaluate effectiveness of in-house intravenous antibiotic treatment in nursing hospitals after the implementation of the specially designed training program. Methods A cohort study of nursing home residents to evaluate a training program for providers, designed to increase awareness and give practical tools for in-house treatment of acute infections. Data obtained included types of infections, antibiotics used, hospital transfer, and length of treatment. Primary outcomes were in-house recovery, hospitalization and mortality. Univariate analysis and multivariable logistic regression analysis to assess association between different factors and recovery. Results A total of 890 cases of acute infections were treated with intravenous antibiotics across 10 nursing homes over a total of 4,436 days. Of these cases, 34.8% were aged 90 years or older. Acute pneumonia was the most prevalent infection accounted for 354 cases (40.6%), followed by urinary tract infections (35.7%), and fever of presumed bacterial infection (17.1%). The mean duration of intravenous antibiotic treatment was 5.09 ± 3.86 days. Of the total cases, 800 (91.8%) recovered, 62 (7.1%) required hospitalization and nine (1.0%) resulted in mortality. There was no significant difference observed in recovery rates across different types of infections. Discussion Appling a simple yet unique intervention program has led to more "in-house" residents receiving treatment, with positive clinical results. Conclusion Treating in-house nursing home residents with acute infections resulted in high recovery rates. Special education programs and collaboration between healthcare organizations can improve treatment outcomes and decrease the burden on the healthcare system.

Which Nursing Home Residents With Pneumonia Are Managed On-Site and Which Are Hospitalized? Results from 2 Years' Surveillance in 14 US Homes. J Am Med Dir Assoc 2020; 21:1862-1868.e3. [PMID: 32873473 DOI: 10.1016/j.jamda.2020.07.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 07/14/2020] [Accepted: 07/19/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVES Pneumonia is a frequent cause of hospitalization among nursing home (NH) residents, but little information is available as to how clinical presentation and other characteristics relate to hospitalization, and the differential use of antimicrobials based on hospitalization status. This study examined how hospitalized and nonhospitalized NH residents with pneumonia differ. DESIGN Data from a 2-year prospective study of residents who participated in a randomized controlled trial. SETTING AND PARTICIPANTS All residents from 14 NHs in North Carolina followed for pneumonia over a 2-year period. METHODS Clinical features, antimicrobial treatment, hospitalization, and demographic data on residents with a pneumonia diagnosis were abstracted from charts; NH information was obtained from NH administrators. RESULTS A total of 509 pneumonia episodes were reported for 395 unique residents; the incidence was not higher in the winter months, and 28% were hospitalized. The likelihood of hospitalization did not differ by clinical characteristics except that residents with a respiratory rate >25 breaths per minute were more likely to be hospitalized. Being on hospice [odds ratio (OR) 3.3, 95% confidence interval (CI) 1.5-7.4] and not having dementia (OR 1.9, 95% CI 1.1-3.2) also related to increased likelihood of hospitalization. Fluoroquinolone (usually levofloxacin) monotherapy was the most common treatment (54%) in both settings, and ceftriaxone monotherapy varied by hospitalization status (7% of hospitalized vs 16% treated on-site). Approximately 36% of nonhospitalized residents received antimicrobials for more than 7 days. CONCLUSIONS/IMPLICATIONS Respiratory rate is associated with hospitalization but was not documented for more than a quarter of residents, suggesting the clinical benefit of more consistently conducting this assessment. Differential hospitalization rates for persons with dementia and on hospice suggest that care is being tailored to individuals' wishes, but this assumption merits study, as does use of fluoroquinolones (due to side effects) and treatment duration (due to potential contribution to antibiotic resistance).

Abstract
OBJECTIVES The aim of this research was to determine the prevalence of urinary tract infections (UTIs) in 2 aged care homes (ACHs) and examine the extent to which presumed UTIs met the 2012 McGeer infection surveillance definitions. DESIGN Retrospective observational study. SETTING Two ACHs: a 30-bed facility and a 100-bed facility PARTICIPANTS: Residents of the 2 ACHs diagnosed with UTI. METHODS A retrospective review was conducted of UTIs clinically diagnosed at the 2 facilities over a 16-month period, utilizing surveillance and microbiologic data, resident progress notes, and medication charts. This data was reviewed to determine how many diagnosed UTIs met the revised McGeer definitions. RESULTS Overall, 119 UTIs were diagnosed in 57 residents over 16 months. Only 7 of the diagnosed UTIs met the McGeer definitions. Forty-seven did not meet the clinical evidence, 17 did not meet the microbiologic evidence, and 48 did not meet either surveillance criteria. CONCLUSIONS This study demonstrated the disparity between the clinical diagnosis of UTI and the surveillance definitions for UTI, and highlights the limitations of the McGeer definitions in those with cognitive or communication deficits. There is an urgent need for antimicrobial stewardship programs and education in the ACH setting.

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
OBJECTIVE Diagnosing stroke-associated pneumonia (SAP) is challenging and may result in inappropriate antibiotic use or confound research outcomes. This study evaluates the diagnostic accuracy of algorithm-defined versus physician-diagnosed SAP in 1088 patients who had dysphagic acute stroke from 37 UK stroke units between 21 April 2008 and 17 May 2014. METHODS SAP in the first 14 days was diagnosed by a criteria-based algorithm applied to blinded patient data and independently by treating physicians. Patients in whom diagnoses differed were reassigned following blinded adjudication of individual patient records. The sensitivity, specificity, positive predictive value (PPV) and diagnostic OR of algorithmic and physician diagnosis of SAP were assessed using adjudicated SAP as the reference standard. Agreement was assessed using the κ statistic. RESULTS Physicians diagnosed SAP in 176/1088 (16%) and the algorithm in 123/1088 (11.3%) patients. Diagnosis agreed in 885/1088 (81.3%) patients (κ 0.22 (95% CI 0.14 to 0.29)). On a blinded review, 129/1088 (11.8%) patients were adjudicated as patients with SAP. The algorithm and the physicians had high specificity (97% (95% CI 96% to 98%) and 90% (95% CI 88% to 92%), respectively) but only moderate sensitivity (72% (95% CI 64% to 80%) and 65% (95% CI 56% to 73%), respectively) in diagnosing SAP. The algorithm showed better PPV (76% (95% CI 67% to 83%) vs 48% (95% CI 40% to 55%)), diagnostic OR (80 (95% CI 42 to 136) vs 18 (95% CI 12 to 27)) and agreement (κ 0.70 (95% CI 0.63 to 0.78) vs 0.48 (95% CI 0.41 to 0.54)) than physician diagnosis with adjudicated SAP. CONCLUSIONS Algorithm-based approaches can standardise SAP diagnosis for clinical practice and research. TRIAL REGISTRATION NUMBER ISRCTN37118456; Post-results.

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
Assessment of body temperature is important for decisions in nursing care, medical diagnosis, treatment and the need of laboratory tests. The definition of normal body temperature as 37°C was established in the middle of the 19th century. Since then the technical design and the accuracy of thermometers has been much improved. Knowledge of physical influence on the individual body temperature, such as thermoregulation and hormones, are still not taken into consideration in body temperature assessment. It is time for a change; the unadjusted mode should be used, without adjusting to another site and the same site of measurement should be used as far as possible. Peripheral sites, such as the axillary and the forehead site, are not recommended as an assessment of core body temperature in adults. Frail elderly individuals might have a low normal body temperature and therefore be at risk of being assessed as non-febrile. As the ear site is close to the hypothalamus and quickly responds to changes in the set point temperature, it is a preferable and recommendable site for measurement of body temperature.

Abstract
AIM To explore early nonspecific signs and symptoms of infection in elderly institutionalized individuals as described by nursing assistants. BACKGROUND Nonspecific signs and symptoms and lack of specific ones are common in connection with infection in institutionalized elderly persons and contribute to a delayed diagnosis and treatment. In clinical care, the nurse makes notes on the individual status of the patient on a daily basis and decides whether to contact the physician or not. However, in Sweden nursing assistants provide most of the daily care and therefore have many opportunities to observe subtle changes that may be early signs of infection. METHOD Data were collected in 2006 from focus interviews with 21 female nursing assistants. The interviews were verbatim transcripted and analysed with qualitative content analysis for manifest content with no preconceived categories. FINDINGS Nursing assistants' descriptions of nonspecific signs and symptoms of infection comprised two exclusive categories. Is not as usual described general signs and symptoms of discomfort related to possible infection, such as discomfort, unrestrained behaviour, aggressiveness, restlessness, confusion, tiredness and feebleness, and decreased eating. Seems to be ill was more distinctly related to signs and symptoms of established infection in general terms of fever and pain or more specifically related to pneumonia, urinary tract infection, skin infection, cold and eye infection. CONCLUSION Nursing assistants have a keen observational ability to detect early signs that might help to confirm suspected infections in elderly nursing home residents early on. Whether or not the cited categories are actual early signs and symptoms of infectious disease needs to be further investigated.

Abstract
The rate of healthcare-associated infections can be regarded as an important outcome parameter of the hygienic quality of care in nursing homes. Our study aimed to evaluate the applicability of repeated prevalence investigations as a tool for surveillance of healthcare-associated infections in nursing homes. From December 2006 to September 2007 a total of five prevalence investigations were conducted in four nursing homes each (n=2,369 residents). Initially, defined structural and procedural parameters of the hygienic quality of the four nursing homes were evaluated based on a detailed inspection and a checklist including 40 parameters. The results showed a uniformly high level of the hygienic quality with only minor variation (mean 84%, range 75%-93% of parameters fulfilled). In total, the prevalence of healthcare-associated infections was 6.8%, with a marked increase with higher categories of dependency (3.5%, 4.0%, 8.5%, and 12.3%, respectively, in the categories 0, I, II, and III of the German grading of skilled nursing care). Respiratory tract (4.1%), skin/soft tissue (1.5%), and urinary tract infections were the most prevalent healthcare-associated infections. Respiratory tract infections showed a marked seasonal pattern. During the second prevalence investigation (February 2007), an outbreak of upper respiratory tract infections occurred in one of the nursing homes (attack rate, 17%). The crude prevalence rates showed considerable differences between the four nursing homes; however, after adjusting for the different categories of dependency, the standardized infection rates (SIR) were largely comparable (excluding the outbreak). After inclusion of the outbreak, the SIR of the specific nursing home was significantly higher compared to all other nursing homes. In conclusion, our study shows that repeated prevalence investigations can be an easy to use tool for surveillance of healthcare-associated infections as a surrogate parameter of the hygienic quality in nursing homes. This implies a knowledge of the seasonality of specific infections and a risk adjustment according to the categories of dependency. The primary intention of surveillance should be the identification of hygienic problems. However, the resources should preferentially be focused on hygienic structures and processes.

Abstract
In Germany, surveillance of nosocomial infections is obligatory by law in hospitals, but not in long-term care facilities. In long-term care facilities, neither X-ray nor laboratory facilities are available; therefore, special criteria for infection surveillance in these facilities were developed by Mc Geer et al. (1991), based only on observations of the medical staff and foregoing laboratory methods. The practicability of these criteria was assessed in a long-term care facility with an electronic medical documentation system. In a retirement home in Frankfurt/Main, Germany, the residents' symptoms according to McGeer et al. were recorded from January, 1 to June 31, 2006. The study included 278 residents, 45,710 resident days, including 4413 "urinary catheter days" und 6009 "gastric tube days". Based on the symptoms documented in the electronic medical documentation system, the respective diagnoses were obtained. Data on gastrointestinal, bronchial, urinary, and eye infections are reported here, including number of cases as well as incidences per 1000 resident days. The overall incidence rate was 5.07/1000 resident days, including 1.9 gastrointestinal infections, 0.95 bronchitis/pneumonia, and 0.44 urinary infections. Incidence of urinary infections in residents with an indwelling urinary catheter was 2.26/1000 catheter days compared to 0.242/1000 days for those without a catheter. Urinary catheter, however, was not only a risk factor for urinary infections (OR 9.4, 95CI 3.4-25.8) but also for bronchial infections (OR 3.0, 95CI 1.3-6.8), and eye infections (OR 1.6, 95CI 0.4-5.8). Gastric tubes were associated with bronchial infections (OR 3.7; CI 1.7-7.9), eye infections (OR 5.4, CI 1.9-15.2), and urinary infections (OR 2.7, 95CI 0.9-8.2). Urinary or fecal incontinence were not associated with any infections, and age (>80 years) was negatively associated with urinary infections (OR 0.35, significant) and bronchial infections (OR 0.51, significant). Compared with published studies, the incidence rates were comparable. The practicability of the criteria of McGeer et al. could be confirmed - with only slight modification - in a long-term care facility with electronic medical documentation.

Abstract
Approximately 70% of health care associated pathogens are resistant to one or more antibiotics. Experts maintain that most antimicrobial-resistant pathogens develop from antibiotic overuse and inappropriate antibiotic selection or treatment duration. Up to 70% of long-term care residents receive at least one course of an antimicrobial agent during a one-year period. Four types of infections occur most often among long-term care residents: urinary tract, respiratory tract, skin and soft tissue, and gastrointestinal tract, and outbreaks are common. Diagnostic uncertainty, failure to recognize fever's clinical manifestation in the elderly, treatment of asymptomatic bacteriuria, and bacterial colonization contribute to antibiotic overuse. Recent infection control guidelines recommend more targeted antibiotic utilization review. Recommendations are presented for implementing antibiotic utilization programs. Hand washing and other measures, such as droplet precautions, are discussed. Economic disincentives surrounding antimicrobial research are highlighted.

Abstract
Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) are a growing concern in long-term care facilities (LTCF). Epidemiologic studies performed in our area have shown high rates of MRSA colonization in elderly residents, and very high rates in some centres. However, the clinical impact of nasal MRSA colonization is often slight. Prevention of MRSA transmission in LTCF includes the application of simple preventive measures with proven effectiveness, such as hand washing, adequately covering of infected wounds, and proper use of antibiotics, without limiting the activities of colonized residents or carrying out active surveillance.

Abstract
Instituições de longa permanência para idosos interagem periodicamente com hospitais gerais para internações de casos agudos ou dos que necessitam de métodos diagnósticos complexos e da atenção de várias especialidades simultaneamente. A decisão de indicar hospitalização é multifatorial, sendo influenciada por circunstâncias como a gravidade do quadro clínico e a infra-estrutura das instituições de longa permanência para idosos. Internações hospitalares apresentam benefícios e riscos, como o desenvolvimento de iatrogenias, delirium e declínios funcionais, podendo resultar em piora do estado geral e da qualidade de vida do idoso asilado durante e/ou após a hospitalização. O objetivo do estudo foi abordar aspectos peculiares na avaliação, tratamento e manejo de idosos asilados em internações hospitalares, particularmente quanto a cuidados que os auxiliem efetivamente nessas circunstâncias. Discutiram-se situações freqüentes como delirium, iatrogenias, desnutrição, declínio funcional e cuidados paliativos e características próprias de residentes em instituições para idosos durante internações em hospitais gerais.

Abstract
BACKGROUND Staphylococcus aureus is frequently isolated from urine samples obtained from long-term care patients. The significance of staphylococcal bacteriuria is uncertain. We hypothesized that S. aureus is a urinary pathogen and that colonized urine could be a source of future staphylococcal infection. METHODS We performed a cohort study of 102 patients at a long-term care Veterans Affairs facility for whom S. aureus had been isolated from clinical urine culture. Patients were observed via urine and nasal cultures that were performed every 2 months. We determined the occurrence of (1) symptomatic urinary tract infection concurrent with isolation of S. aureus (by predetermined criteria), (2) staphylococcal bacteremia concomitant with isolation of S. aureus from urine, and (3) subsequent episodes of staphylococcal infection. RESULTS Of 102 patients, 82% had undergone recent urinary catheterization. Thirty-three percent of patients had symptomatic urinary tract infection at the time of initial isolation of S. aureus, and 13% were bacteremic. Eight-six percent of the initial urine isolates were methicillin-resistant S. aureus. Seventy-one patients had follow-up culture data; 58% of cultures were positive for S. aureus at > or =2 months (median duration of staphylococcal bacteriuria, 4.3 months). Sixteen patients had subsequent staphylococcal infections, occurring up to 12 months after initial isolation of S. aureus; 8 late-onset infections were bacteremic. In 5 of 8 patients, the late blood isolate was found to have matched the initial urine isolate by pulsed-field gel electrophoresis typing. CONCLUSIONS S. aureus is a cause of urinary tract infection among patients with urinary tract catheterization. The majority of isolates are methicillin-resistant S. aureus. S. aureus bacteriuria can lead to subsequent invasive infection. The efficacy of antistaphylococcal therapy in preventing late-onset staphylococcal infection in patients with persistent staphylococcal bacteriuria should be tested in controlled trials.

Abstract
The purpose of this study was to identify, in the presence of significant bacteriuria, the symptoms that determine and conditions that affect whether a physician will begin antibiotic treatment in the elderly; 2 physician groups were studied: geriatric physicians and family practice/internal medicine physicians. We also sought to compare these results to symptoms and conditions that determine nurses' decisions to begin assessment for urinary tract infections (UTIs) in this population. We also sought to determine the importance these 3 groups placed of monitoring asymptomatic bacteriuria for specific elderly patient populations. Quantitative questionnaires were sent to a convenience sample of 1900 physicians and nurses. Sixty-eight of the 300 geriatric physicians (23%), 113 of the 1000 family practice or internal medicine physicians (11%), and 192 of the 600 nurses (32%) returned surveys. Results showed differences between physician groups and nurses concerning whether cloudy and malodorous urine were symptoms of a UTI. This survey also found that physicians consider patient conditions to a greater extent than nurses do in their decisions regarding UTIs. Geriatric physicians appear to be less likely to monitor asymptomatic bacteriuria in any elderly patient population. Finally, we found that with regard to monitoring asymptomatic bacteriuria, both physician groups and the nurse group gave the greatest support for monitoring among elderly who have difficulty presenting symptoms of a UTI.

Abstract
Asymptomatic bacteriuria is considered a transient and benign condition in the geriatric population. Before a diagnosis of a urinary tract infection (UTI) can be made, symptoms and significant bacteriuria must be present. One of these symptoms is malodorous urine. Other symptoms of a UTI, typical in the younger population, have been found to be absent or misleading in the older adult population. Though early detection of UTIs improves outcomes, unnecessary laboratory tests are costly and time-consuming, and may encourage inappropriate antibiotic therapy. The purpose of this study was to determine if urine odor is an accurate predictor of a UTI in the older adult incontinent nursing home population. Ninety-seven recently wet incontinence pads of residents in six Midwestern nursing homes were evaluated for odor within 1 hour of voiding. These results were compared to microscopy and culture results of clean-catch urine samples from these individuals. Defining a UTI as either bacteriuria or bacteriuria and pyuria, using urine odor to identify a UTI resulted in error in one third of cases. Results of this study indicate smell of urine in incontinence pads may be an absent or misleading symptom for UTIs in elderly nursing home residents.

Abstract
OBJECTIVES To determine the relationship between infections and functional impairment in nursing home residents. DESIGN Prospective cohort study (follow-up period, 6 months). SETTING Thirty-nine nursing homes in western Switzerland. PARTICIPANTS A total of 1,324 residents aged 65 and older (mean age 85.7; 76.6% female) who agreed to participate, or their proxies, by oral informed consent. MEASUREMENTS Functional status measured every 3 months. Two different outcomes were used: (a) functional decline defined as death or decreased function at follow-up and (b) functional status score using a standardized measure. RESULTS At the end of follow-up, mortality was 14.6%, not different for those with and without infection (16.2% vs 13.1%, P=.11). During both 3-month periods, subjects with infection had higher odds of functional decline, even after adjustment for baseline characteristics and occurrence of a new illness (adjusted odds ratio (AOR)=1.6, 95% confidence interval (CI)=1.2-2.2, P=.002, and AOR=1.5, 95% CI=1.1-2.0, P=.008, respectively). The odds of decline increased in a stepwise fashion in patients with zero, one, and two or more infections. The analyses predicting functional status score (restricted to subjects who survived) gave similar results. A survival analysis predicting time to first infection confirmed a stepwise greater likelihood of infection in subjects with moderate and severe impairment at baseline than in subjects with no or mild functional impairment at baseline. CONCLUSION Infections appear to be both a cause and a consequence of functional impairment in nursing home residents. Further studies should be undertaken to investigate whether effective infection control programs can also contribute to preventing functional decline, an important component of these residents' quality of life.

Abstract
The purpose of this research was to clarify the possible changes brought about by the introduction of the long-term care insurance system in terms of number of communication/recording tasks, related nursing services in use, and when and where these tasks were performed. By examining the detailed content of communication/recording tasks, this study also sought to explore the advantages of introducing information technology (IT) systems in nursing service settings. The study was designed before-and-after study in two sessions, February 2000 and August 2000, namely before and after the introduction of Japan's long-term care insurance system. Participants were clients using the institution's in-home nursing services and all staff in a medical institution located in the Mikawa region of Aichi Prefecture, Japan. Following measurements were performed: (1). nursing service in use, (2). type of job, (3). date and time, (4). from whom, (5). to whom, (6). communication tool and (7). content, related to a particular communication. Communication/recording tasks were frequently performed around the starting and closing time of services. Following the adoption of the new system, these tasks tended to occur mostly around the starting time of services. As for the staff, the involvement of the professional carers increased. Regarding content of communication/recording, reports, confirmation and instruction increased. In conclusion, the use of IT driven devices is recommended to streamline the performance of communication/recording tasks as well as to ease the rush of these tasks thereby improving the quality of nursing services.

Abstract
PURPOSE To determine whether unrecognized Clostridium difficile infection is responsible for a substantial proportion of cases of unexplained leukocytosis in a tertiary care hospital setting. METHODS We prospectively identified 60 patients who had unexplained leukocytosis (white blood cell count > or =15,000/mm3). Fecal specimens were tested for C. difficile toxin using an enzyme immunosorbent assay. We compared the clinical features of patients who had positive or negative assay results, as well as of 26 hospitalized control patients who did not have unexplained leukocytosis. RESULTS Thirty-five (58%) of the patients with unexplained leukocytosis had C. difficile toxin in at least one fecal specimen as compared with 3 (12%) of the controls (P <0.001). Symptoms of colitis were often mild or absent at the time the white blood cell count was first elevated or, if present, had not been recognized by the attending physicians. Leukocytosis resolved promptly in most patients who were treated with metronidazole. In the 25 patients (42%) who had a negative test for C. difficile toxin, leukocytosis also tended to resolve during empiric therapy with metronidazole; some of these patients may have had C. difficile infection. CONCLUSION The majority of patients in our hospital who had unexplained leukocytosis had C. difficile infection. Unexplained leukocytosis in hospitalized patients should prompt a search for symptoms and signs consistent with C. difficile infection and a study to detect C. difficile. Empiric therapy with metronidazole may be effective in the appropriate epidemiologic setting.

Abstract
Average life expectancy throughout developed countries has rapidly increased during the latter half of the 20th century and geriatric infectious diseases have become an increasingly important issue. Infections in the elderly are not only more frequent and more severe, but they also have distinct features with respect to clinical presentation, laboratory results, microbial epidemiology, treatment, and infection control. Reasons for increased susceptibility include epidemiological elements, immunosenescence, and malnutrition, as well as a large number of age-associated physiological and anatomical alterations. Moreover, ageing may be the cause of infection but infection can also be the cause of ageing. Mechanisms may include enhanced inflammation, pathogen-dependent tissue destruction, or accelerated cellular ageing through increased turnover. In most instances, treatment of infection leads to a satisfactory outcome in the elderly. However, in palliative care situations and in patients with terminal dementia, the decision whether or not to treat an infectious disease is becoming a difficult ethical issue.
