[PMID: 37421830 DOI: 10.1016/j.ijnurstu.2023.104555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 05/10/2023] [Accepted: 06/09/2023] [Indexed: 07/10/2023]
Abstract
BACKGROUND This systematic review examines the prevalence of indwelling urinary catheters in nursing home residents. METHODS MEDLINE via PubMed, CINAHL, and EMBASE were searched from inception to 9 August 2022. Cross-sectional studies and longitudinal studies with cross-sectional analyses reporting catheter prevalence in nursing home residents were identified and summarized descriptively. Study quality was assessed using the Joanna Briggs Institute's tool. RESULTS Sixty-seven studies (92.5 % cross-sectional) were included. The reported number of included residents ranged from 73 to 110,656. The median catheter prevalence was 7.3 % (interquartile range 4.3-10.1 %; n = 65 studies). It was higher in Germany (10.2 % [9.7-12.8 %]; n = 15) than in the United States of America (9.3 % [6.3-11.9 %]; n = 9), United Kingdom (6.9 % [4.8-8.5 %]; n = 7), and Sweden (7.3 % [6.4-7.9 %]; n = 6). Furthermore, it was higher among men (17.0 % [16.0-26.0 %]) than among women (5.3 % [4.0-9.5 %]) (n = 9). Only one study investigated differences by age. The prevalence was higher for transurethral (5.7 % [5.6-7.2 %]; n = 12) than for suprapubic (1.2 % [0.6-2.5 %]; n = 13) catheters. Most catheterized residents were long-term catheterized (n = 6) and had their catheter changed within 3 months (n = 2). Symptomatic urinary tract infections were more common among catheterized than among non-catheterized residents (n = 4). DISCUSSION Catheter prevalence in nursing home residents varies between studies and countries. Prevalence differences by sex, age, and catheter type as well as duration of catheterization, catheter change intervals, and catheter-associated urinary tract infections are rarely reported because most studies do not primarily focus on catheters. Future studies should focus on the circumstances of urinary catheter use and care in nursing home residents. REGISTRATION AND FUNDING PROSPERO (29 August 2022; CRD42022354358); no funding.

[PMID: 38813006 PMCID: PMC10763801 DOI: 10.55730/1300-0144.5706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 10/26/2023] [Accepted: 05/09/2023] [Indexed: 05/31/2024] Open
Abstract
Background/aim Older adults tend to have more urinary tract infections (UTIs). The frequency of recurrent lower urinary tract infections (rLUTIs) increases with age. rLUTIs are associated with long-term chronic effects on geriatric syndromes in older adults. We aimed to investigate possible risk factors that influence rLUTIs in older adults based on comprehensive geriatric assessment (CGA). Materials and methods This cross-sectional study included 235 older adults admitted to Gaziantep University's Geriatric Outpatient Clinic between June 1 and November 30, 2022. All patients underwent CGA. The Geriatric Depression Scale (GDS), the European Quality of Life-Five Dimension (EQ-5D) questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Katz Index of Activities of Daily Living (ADL), the Lawton and Brody Index of Instrumental Activities of Daily Living (IADL), and the Mini Nutritional Assessment (MNA) tool were,administered. Handgrip strength (HGS) and gait speed were also measured, and the number of falls in the last year was recorded. Results The mean age of the participants was 72.8 ± 6.8 years and 61.3% were female. Sixty-four patients had rLUTIs. The rLUTI group had higher frequencies of sarcopenia, hypertension, and diabetes; higher numbers of comorbidities and medications; higher GDS and PSQI scores; and more reported falls. They had lower ADL, MNA, EQ-5D, and gait speed scores. HGS was found to be lower in women with rLUTIs. Higher numbers of comorbidities and GDS scores and lower HGS were independent predictors of rLUTIs in women (p = 0.011, OR: 1.75; p = 0.018, OR: 1.14; and p = 0.042, OR: 0.91, respectively). Conclusion We revealed that decreased HGS, higher GDS, and the number of comorbidities in older women were independent risk factors for rLUTIs. Our findings offer a new perspective on the importance of CGA in diagnosing and preventing rLUTIs.

Abstract
With the increase in the aging population, age-related conditions such as dementia and Alzheimer's disease will become ever more prevalent in society. As there is no cure for dementia and extremely limited therapeutic options, researchers are examining the mechanisms that contribute to the progression of cognitive decline in hopes of developing better therapies and even an effective, long-lasting treatment for this devastating condition. This review will provide an updated perspective on the role of immunity in triggering the changes that lead to the development of dementia. It will detail the latest findings on Aβ- and tau-induced microglial activation, including the role of the inflammasome. The contribution of the adaptive immune system, specifically T cells, will be discussed. Finally, whether the innate and adaptive immune system can be modulated to protect against dementia will be examined, along with an assessment of the prospective candidates for these that are currently in clinical trials.

Abstract
Background: In patients with Alzheimer’s disease (AD), bacterial infections are often associated with a cognitive decline. Animal models of genuine acute infections with viable bacteria which induce deterioration of neurodegenerative diseases are missing. Objective: We assessed the effect of an intracerebral infection with E. coli in a mouse model of AD. Methods: 13-month-old Tg2576 +/- mice and transgene negative littermates (Tg2576 -/-) received an intracerebral injection with E. coli K1 or saline followed by treatment with ceftriaxone starting 41 h post infection (p.i.) for 5 days. For 4 weeks, mice were monitored for clinical status, weight, motor functions, and neuropsychological status using the Morris water maze. ELISAs, stainings, and immunohistochemistry in brains were performed at the end of the experiment. Results: Mortality of the infection was approximately 20%. After 4 weeks, spatial learning of infected Tg2576 +/- mice was compromised compared to non-infected Tg2576 +/- mice (p < 0.05). E. coli infection did not influence spatial learning in Tg2576 -/- mice, or spatial memory in both Tg2576 +/- and -/- mice within 4 weeks p.i.. Necrosis of hippocampal neurons was induced in infected compared to non-infected Tg2576 +/- mice 4 weeks p.i., whereas brain concentrations of Aβ1–40, Aβ1–42, and phosphoTau as well as axonal damage and microglia density were not altered. Conclusion: Here, we proved in principle that a genuine acute bacterial infection can worsen cognitive functions of AD mice. Mouse models of subacute systemic infections are needed to develop new strategies for the treatment of bacterial infections in patients with AD in order to minimize their cognitive decline.

Antibiotics (Basel) 2022; 11:antibiotics11020140. [PMID: 35203742 PMCID: PMC8868192 DOI: 10.3390/antibiotics11020140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 01/15/2022] [Accepted: 01/18/2022] [Indexed: 02/04/2023] Open
Abstract
The aim of this cohort study was to identify resident-related factors that influence antibiotic treatment decisions for urinary tract infections (UTIs) in nursing home residents and to provide an overview of the appropriateness of antibiotic treatment decisions according to the updated Dutch guideline for UTIs in frail older adults. The PROGRESS study dataset, consisting of 298 suspected UTI episodes in Dutch nursing home residents, was used. The presence of dysuria was associated with the highest frequency of antibiotic prescription (87.8%). Positive leukocyte esterase dipstick results showed the greatest increase in the risk of antibiotic prescription (RR 2.1, 95% CI 1.44 to 3.06). Treatment decisions were considered adequate in 64.1% of the suspected UTI episodes. Overtreatment occurred more often than undertreatment. Of the inadequate treatment decisions, 29.3% was due to treatment of UTI episodes in which solely non-specific symptoms were present. A high proportion of nitrofurantoin prescriptions were incorrect in UTIs with signs of tissue invasion (54.8%), indwelling catheter-associated UTIs (37.5%), and UTIs in men (29.2%). Although this is considered inadequate, non-specific symptoms were associated with antibiotic prescription for suspected UTIs in Dutch nursing home residents and nitrofurantoin was inadequately prescribed in particular groups, such as men.

Abstract
BACKGROUND The burden of healthcare-associated infections (HAIs) and antimicrobial use in Swiss long-term care facilities (LTCFs) is currently unknown. This study assessed the prevalence of HAIs and antibiotic use among LTCF residents in Switzerland. METHODS A point-prevalence study was undertaken in LTCFs in eastern and western Switzerland from August to October 2019 according to the 'Healthcare-associated infections in long-term care facilities' (HALT) protocol. Characteristics of residents (age, sex, wounds, dementia, indwelling catheters) and institutions (specific factors, geographic region) were assessed. LTCF residents were screened for HAIs and current antibiotic treatment. Personal and institutional factors associated with HAIs were assessed. RESULTS In total, 1185 residents from 16 LTCFs (eight per geographic region) were screened for HAIs and antibiotic treatment. Median age was 87 years (interquartile range 79-91) and 71% were female. The prevalence of HAIs was 4.2% (west 4.3% vs east 4.2%; P=0.93), with mucocutaneous skin infections (36%) and respiratory tract infections (30%) being the most common. Independent risk factors for the presence of HAIs were presence of a chronic wound [odds ratio (OR) 2.4, 95% confidence interval (CI) 1.1-5.0; P=0.02] and being immobile (OR 1.8, 95% CI 1.0-3.3; P=0.04). Antibiotics were given to 2.9% of residents (west 3.9% vs east 1.8%; P=0.05) on the day of the survey. The most commonly prescribed antibiotics were amoxicillin-clavulanic acid and quinolones. CONCLUSIONS The prevalence of HAIs in Swiss LTCFs is similar to that in other European countries, whereas antibiotic consumption is lower. Further point-prevalence surveys on a broader scale are recommended to improve understanding of the burden of HAIs and antibiotic consumption in this setting.

Prospective Surveillance of Healthcare-Associated Infections in Residents in Four Long-Term Care Facilities in Graz, Austria. Antibiotics (Basel) 2021; 10:antibiotics10050544. [PMID: 34067175 PMCID: PMC8151996 DOI: 10.3390/antibiotics10050544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 05/04/2021] [Accepted: 05/04/2021] [Indexed: 12/05/2022] Open
Abstract
Healthcare-associated infections (HCAI) are a common cause for residents’ mortality and morbidity associated with a significant socio-economic burden. Data on HCAIs in Austrian long-term care facilities are scare. Therefore, we evaluated the incidence rate of HCAIs per 1000 resident days in four LTC facilities in Graz, Austria, characterized the spectrum of HCAIs and the use of antimicrobial substances. We conducted a prospective surveillance study from 1 January to 31 December 2018 in four LTCFs of the Geriatric Health Centre of the City of Graz (total of 388 beds). Nursing staff collected data on HCAIs once a week using an electronic reporting system. During the 12-month surveillance period, 252 infections of 165 residents were recorded. The overall incidence rate of HCAIs was 2.1 per 1000 resident days. Urinary tract infections were the most commonly recorded HCAIs (49%, 124/252, 1.03 per 1000 resident days), followed by skin and soft tissue infections and respiratory tract infections. Beta-lactams (ATC class J01C) were prescribed most frequently (63/212), followed by fluoroquinolones (J01M; 54/212). In conclusion, the overall incidence rate for HCAIs was relatively low at 2.1 per 1000 resident days. Our real-life data can serve as a basis for future antimicrobial stewardship and infection prevention interventions.

Surveillance of infections in long-term care facilities (LTCFs): The impact of participation during multiple years on health care-associated infection incidence. Epidemiol Infect 2019; 147:e266.

Abstract
We studied trends in the incidence of health care-associated infections (HAIs) in LTCFs between 2009 and 2015 and determined the effect of participation in our network. Elder-care physicians reported weekly the number of cases of influenza-like illness, gastroenteritis, (probable) pneumonia, urinary tract infections (UTIs) and all-cause mortality. Trends in the incidence of infection and mortality in relation to LTCF characteristics were calculated using multilevel univariate and multivariate logistic regression. Thirty LTCF participated for 3 years or more, 16 for 2 years and the remaining 12 LTCF for 1 year. During the study period, the median number of beds decreased from 158 to 139, whereas the percentage of residents with private bedrooms increased from 14% to 87%. UTIs were the most frequently reported infections, followed by (probable) pneumonia and gastroenteritis. Adjusted for calendar year and season, we observed a statistically significant decrease in the incidence of influenza-like illness (odds ratio (OR) = 0.8, P < 0.01) and (probable) pneumonia (OR = 0.8, P < 0.01) for each extra year an LTCF participated. Although there are other likely contributors, such as more private rooms and enhanced infection control measures, the decreasing trend of HAI in LTCFs participating in surveillance implies that surveillance is a valuable addition to current strategies to optimise infection control.

BMC Geriatr 2019; 19:210. [PMID: 31382895 PMCID: PMC6683564 DOI: 10.1186/s12877-019-1236-6] [Citation(s) in RCA: 50] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Accepted: 07/30/2019] [Indexed: 11/22/2022] Open
Abstract
Background Respiratory infections among older adults in long-term care facilities (LTCFs) are a major global concern, yet a rigorous systematic synthesis of the literature on the burden of respiratory infections in the LTCF setting is lacking. To address the critical need for evidence regarding the global burden of respiratory infections in LTCFs, we assessed the burden of respiratory infections in LTCFs through a systematic review of the published literature. Methods We identified articles published between April 1964 and March 2019 through searches of PubMed (MEDLINE), EMBASE, and the Cochrane Library. Experimental and observational studies published in English that included adults aged ≥60 residing in LTCFs who were unvaccinated (to identify the natural infection burden), and that reported measures of occurrence for influenza, respiratory syncytial virus (RSV), or pneumonia were included. Disagreements about article inclusion were discussed and articles were included based on consensus. Data on study design, population, and findings were extracted from each article. Findings were synthesized qualitatively. Results A total of 1451 articles were screened for eligibility, 345 were selected for full-text review, and 26 were included. Study population mean ages ranged from 70.8 to 90.1 years. Three (12%) studies reported influenza estimates, 7 (27%) RSV, and 16 (62%) pneumonia. Eighteen (69%) studies reported incidence estimates, 7 (27%) prevalence estimates, and 1 (4%) both. Seven (27%) studies reported outbreaks. Respiratory infection incidence estimates ranged from 1.1 to 85.2% and prevalence estimates ranging from 1.4 to 55.8%. Influenza incidences ranged from 5.9 to 85.2%. RSV incidence proportions ranged from 1.1 to 13.5%. Pneumonia prevalence proportions ranged from 1.4 to 55.8% while incidence proportions ranged from 4.8 to 41.2%. Conclusions The reported incidence and prevalence estimates of respiratory infections among older LTCF residents varied widely between published studies. The wide range of estimates offers little useful guidance for decision-making to decrease respiratory infection burden. Large, well-designed epidemiologic studies are therefore still necessary to credibly quantify the burden of respiratory infections among older adults in LTCFs, which will ultimately help inform future surveillance and intervention efforts.

Abstract
BACKGROUND Nursing home residents and older hospitalized patients have a significantly higher risk to suffer from nosocomial infections (NI). It is still an unanswered question whether patients suffering from NI are at greater risk for deterioration of activities of daily living. MATERIAL AND METHODS In a retrospective observational study, we evaluated the prevalence of NI during hospitalization of acute geriatric inpatients of the geriatric department at Jena University Hospital by patient records. The study included data from 555 patients, hospitalized from 1 August 2011 to 31 August 2012. We included patients without acute complications and those who developed NI after the second day of hospitalization. RESULTS Every third patient developed a NI during the observation period. Consequently, the incidence of NI was approximately 18 patients with NI per 1000 days of hospitalization. This rate was considerably higher than the national average. The most frequent NIs were urinary tract infection, gastroenteritis and infections of the lower respiratory tract. A low value of Barthel index at admission, high multimorbidity index and transurethral indwelling catheters promoted the development of NI. An improvement in activities of daily living, assessed by mean values of the difference in the Barthel index, was significantly lower in patients who developed NI (mean value14.5 ± 16.3) than in patients who did not (mean value 18.1 ± 14.8). CONCLUSION Nosocomial infections were a relevant factor for deterioration of the Barthel Index, at least temporarily and NIs, in particular the combination of several NIs, jeopardized an improvement in the activities of daily living. This was particularly true for infections of the lower respiratory tract and gastroenteritis.

Abstract
Previously, the contribution of peripheral infection to cognitive decline was largely overlooked however, the past 15 years have established a key role for infectious pathogens in the progression of age-related neurodegeneration. It is now accepted that the immune privilege of the brain is not absolute, and that cells of the central nervous system are sensitive to both the inflammatory events occurring in the periphery and to the infiltration of peripheral immune cells. This is particularly relevant for the progression of Alzheimer’s disease, in which it has been demonstrated that patients are more vulnerable to infection-related cognitive changes. This can occur from typical infectious challenges such as respiratory tract infections, although a number of specific viral, bacterial, and fungal pathogens have also been associated with the development of the disease. To date, it is not clear whether these microorganisms are directly related to Alzheimer’s disease progression or if they are opportune pathogens that easily colonize those with dementia and exacerbate the ongoing inflammation observed in these individuals. This review will discuss the impact of each of these challenges, and examine the changes known to occur with age in the peripheral immune system, which may contribute to the age-related vulnerability to infection-induced cognitive decline.

Abstract
BACKGROUND The knowledge on viral respiratory infections in nursing home (NH) residents and their caregivers is limited. The purpose of the present study was to assess and compare the incidence of acute respiratory infections (ARI) in nursing home (NH) residents and staff, to identify viruses involved in ARI and to correlate viral etiology with clinical manifestations of ARI. METHODS The prospective surveillance study was accomplished in a medium-sized NH in Slovenia (central Europe). Ninety NH residents and 42 NH staff were included. Nasopharyngeal swabs were collected from all participants at enrollment (December 5th, 2011) and at the end of the study (May 31st, 2012), and from each participant that developed ARI within this timeframe. Molecular detection of 15 respiratory viruses in nasopharyngeal swab samples was performed. RESULTS The weekly incidence rate of ARI in NH residents and NH staff correlated; however, it was higher in staff members than in residents (5.9 versus 3.8/1,000 person-days, P = 0.03), and was 2.5 (95 % CI: 1.36-4.72) times greater in residents without dementia than in residents with dementia. Staff members typically presented with upper respiratory tract involvement, whereas in residents lower respiratory tract infections predominated. Respiratory viruses were detected in 55/100 ARI episodes. In residents, influenza A virus, respiratory syncytial virus, and human metapneumovirus were detected most commonly, whereas in NH staff rhinovirus and influenza A virus prevailed. 38/100 ARI episodes (30/56 in residents, 8/44 in staff) belonged to one of three outbreaks (caused by human metapneumovirus, influenza A virus and respiratory syncytial virus, respectively). NH residents had higher chances for virus positivity within outbreak than HN staff (OR = 7.4, 95 % CI: 1.73-31.48, P < 0.01). CONCLUSIONS ARI are common among NH residents and staff, and viruses were detected in a majority of the episodes of ARI. Many ARI episodes among NH residents were outbreak cases and could be considered preventable. TRIAL REGISTRATION The study was registered on the 1th of December 2011 at ClinicalTrials ( NCT01486160 ).

Abstract
OBJECTIVES Infections and colonisations with multidrug-resistant organisms (MDROs) increasingly affect different types of healthcare facilities worldwide. So far, little is known about additional costs attributable to MDROs outside hospitals. The aim of this study was to analysis the economic burden of multidrug-resistant bacteria in nursing homes in Germany. SETTING The cost analysis is performed from a microeconomic perspective of the healthcare facilities. Study took place in six long-term care facilities in north-eastern Germany. PARTICIPANTS Data of 71 residents with a positive MDRO status were included. PRIMARY AND SECONDARY OUTCOME MEASURES The study analysed MDRO surveillance data from 2011 to 2013. It was supplemented by an empirical analysis to determine the burden on staff capacity and materials consumption. RESULTS 11,793 days with a positive multidrug-resistant pathogen diagnosis could be included in the analysis. On average, 11.8 (SD ± 6.3) MDRO cases occurred per nursing home. Mean duration per case was 163.3 days (SD ± 97.1). The annual MDRO-related costs varied in nursing homes between €2449.72 and €153,263.74 on an average €12,682.23 per case. Main cost drivers were staff capacity (€43.95 per day and €7177.04 per case) and isolation materials (€24.70 per day and €4033.51 per case). CONCLUSIONS The importance of MDROs in nursing homes could be confirmed. MDRO-related cost data in this specific healthcare sector were collected for the first time. Knowledge about the burden of MDROs will enable to assess the efficiency of hygiene intervention measures in nursing homes in the future.

Abstract
Because of the lack of structural and human resources for implementing more effective and safe preventive procedures, antimicrobial prophylaxis is often used to prevent infections in nursing homes. However, if data on the efficacy of antibiotic prophylaxis in nursing homes are null, there is a plenty of evidence that the inappropriate use of antimicrobials in this setting is associated with a high rate of colonization and infection with multi-drug-resistant organisms (MDROs), and of Clostridium difficile infection (CDI). Here, we have reviewed the infection epidemiology, the burden of MDROs and CDI, the antibiotic use and some potential infection preventive measures in nursing homes, pointing up the peculiarities of this setting and the absolute need of a more prudential use of antimicrobials.

Abstract
Acute infection of the urinary tract is one of the most commonly encountered bacterial infections in the frail elderly population and is responsible for substantial morbidity and recurrent infections with antibiotic resistance. Although generally considered to be self-limiting without treatment or easily treated with a short antibiotic regime, urinary tract infections (UTIs) often have a dramatic history, associated with incomplete resolution and frequent recurrence. The biological complexity of the infections combined with a dramatic rise in antibiotic-resistant pathogens highlight the need for an anticipating strategy for therapy necessary for a rapid recovery. The first crucial step is the classification in asymptomatic bacteriuria or complicated pyelonephritis, on which the decision for the intensity of treatment and diagnostic effort is based. For the selection of empiric antibiotic therapy, knowledge about the predominant uropathogens as well as local resistance patterns is important. In this manner, most urinary tract infections in the elderly can be treated without greater expense.

Abstract
Background: The increase of multidrug-resistant organisms (MDROs) causes problems in geriatric nursing homes. Older people are at increased a growing risk of infection due to multimorbidity and frequent stays in hospital. A high proportion of the elderly require residential care in geriatric nursing facilities, where hygiene requirements in nursing homes are similar to those in hospitals. For this reason we examined how well nursing homes are prepared for MDROs and how effectively protect their infection control residents and staff. Methods: A cross-sectional study was performed on infection control in residential geriatric nursing facilities in Germany 2012. The questionnaire recorded important parameters of hygiene, resident and staff protection and actions in case of existing MDROs. Results: The response was 54% in Hamburg and 27% in the rest of Germany. Nursing homes were generally well equipped for dealing with infection control: There were standards for MDROs and regular hygiene training for staff. The facilities provided adequate protective clothing, affected residents are usually isolated and hygienic laundry processing conducted. There are deficits in the communication of information on infected residents with hospitals and general practitioners. 54% of nursing homes performed risk assessments for staff infection precaution. Conclusion: There is a growing interest in MDROs and infection control will be a challenge in for residential geriatric nursing facilities in the future. This issue has also drawn increasing attention. Improvements could be achieved by improving communication between different participants in the health service, together with specific measures for staff protection at work.

Abstract
The demographics of the healthcare population are changing, with an ever-greater proportion of people being treated outside the traditional hospital setting through community healthcare. This shift in the way that healthcare is delivered raises new concerns over community healthcare-associated infections (HCAIs). A literature search between 2000 and December 2013 was conducted in databases including PubMed, SciVerse ScienceDirect and Google Scholar. National and international guideline and policy documents were searched using Google. Many terms were used in the literature searches, including ‘nosocomial’, ‘healthcare infection’, ‘community’ and ‘nursing home’. The rates of HCAI in community healthcare are similar to the rates found in the acute hospital setting, but the types of infection differ, with a greater focus on urinary tract infections (UTIs) in the community and ventilator-associated pneumonias in the hospital setting. Patients who acquire a community HCAI are more likely to exhibit reduced physical condition, have increased levels of morbidity and have higher mortality rates than individuals without infection. Infection control programmes have been developed worldwide to reduce the rates of hospital HCAIs. Such interventions are equally as valid in the community, but how best to implement them and their subsequent impact are much less well understood. The future is clear: HCAIs in the community are going to become an ever-increasing burden and it is critical that our approach to these infections is brought quickly in line with present hospital sector standards.

Abstract
Residential aged care facilities are increasingly identified as having a high burden of infection, resulting in subsequent antibiotic use, compounded by the complexity of patient demographics and medical care. Of particular concern is the recent emergence of multidrug-resistant organisms among this vulnerable population. Accordingly, antimicrobial stewardship (AMS) programs have started to be introduced into the residential aged care facilities setting to promote judicious antimicrobial use. However, to successfully implement AMS programs, there are unique challenges pertaining to this resource-limited setting that need to be addressed. In this review, we summarize the epidemiology of infections in this population and review studies that explore antibiotic use and prescribing patterns. Specific attention is paid to issues relating to inappropriate or suboptimal antibiotic prescribing to guide future AMS interventions.

Abstract
OBJECTIVES To determine whether cranberry capsules prevent urinary tract infection (UTI) in long-term care facility (LTCF) residents. DESIGN Double-blind randomized placebo-controlled multicenter trial. SETTING Long-term care facilities (LTCFs). PARTICIPANTS LTCF residents (N = 928; 703 women, median age 84). MEASUREMENTS Cranberry and placebo capsules were taken twice daily for 12 months. Participants were stratified according to UTI risk (risk factors included long-term catheterization, diabetes mellitus, ≥ 1 UTI in preceding year). Main outcomes were incidence of UTI according to a clinical definition and a strict definition. RESULTS In participants with high UTI risk at baseline (n = 516), the incidence of clinically defined UTI was lower with cranberry capsules than with placebo (62.8 vs 84.8 per 100 person-years at risk, P = .04); the treatment effect was 0.74 (95% confidence interval (CI) = 0.57-0.97). For the strict definition, the treatment effect was 1.02 (95% CI = 0.68-1.55). No difference in UTI incidence between cranberry and placebo was found in participants with low UTI risk (n = 412). CONCLUSION In LTCF residents with high UTI risk at baseline, taking cranberry capsules twice daily reduces the incidence of clinically defined UTI, although it does not reduce the incidence of strictly defined UTI. No difference in incidence of UTI was found in residents with low UTI risk.

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
Background: ageing is frequently accompanied by a higher incidence of infections and an increase in disability in activities of daily living (ADL). Objective: this study examines whether clinical infections [urinary tract infections (UTI) and lower respiratory tract infections (LRTI)] predict an increase in ADL disability, stratified for the presence of ADL disability at baseline (age 86 years). Design: the Leiden 85-plus Study. A population-based prospective follow-up study. Setting: general population. Participants: a total of 154 men and 319 women aged 86 years. Methods: information on clinical infections was obtained from the medical records. ADL disability was determined at baseline and annually thereafter during 4 years of follow-up, using the 9 ADL items of the Groningen Activity Restriction Scale. Results: in 86-year-old participants with ADL disability, there were no differences in ADL increase between participants with and without an infection (−0.32 points extra per year; P = 0.230). However, participants without ADL disability at age 86 years (n = 194; 41%) had an accelerated increase in ADL disability of 1.07 point extra per year (P < 0.001). For UTIs, this was 1.25 points per year (P < 0.001) and for LRTIs 0.70 points per year (P = 0.041). In this group, an infection between age 85 and 86 years was associated with a higher risk to develop ADL disability from age 86 onwards [HR: 1.63 (95% CI: 1.04–2.55)]. Conclusions: among the oldest-old in the general population, clinically diagnosed infections are predictive for the development of ADL disability in persons without ADL disability. No such association was found for persons with ADL disability.

Abstract
BACKGROUND The aim of this study was to assess the prevalence of multidrug-resistant Escherichia coli and extended-spectrum â-lactamases (ESBL) pathogens isolated from asymptomatic bacteriuria and urinary tract infections (UTIs), and the relationship between the phylogeny, antimicrobial resistance, and virulence among isolates in residents of 3 long-term care facilities (LTCF) in Krakow, Poland. MATERIAL AND METHODS This was point prevalence study and prospective infection control in a group of 217 people. Urine samples were examined with standard microbiological methods and screened for the presence of blaCTX-M, blaSHV, and blaTEM. E. coli isolates were screened for 6 common virulence factors (VFs) and classified according to the rapid phylogenetic grouping technique. RESULTS Among all the strains tested, 14 isolates (13.9%) expressed ESBL activity. A significant proportion of isolates were resistant to ciprofloxacin (32.7%, n=33). Resistance to trimethoprim/sulfamethoxazole was identified among 45 isolates (44.5%). Independent risk factors for the presence of an ESBL-producing strain were: UTI, urinary and/or fecal incontinence, bedridden, and low values of the Barthel and Katz Indexes. Gene sequencing identified 8 blaCTX-M-15, 1 blaCTX-M-3, 9 blaTEM-1, and 1 blaSHV-12. Among E. coli, no relationship between number of VF genes and phylogeny was found. The most prevalent virulence factor was fimH (82.1%). CONCLUSIONS The findings of this study emphasize the need for further research on the epidemiology of multi-drug resistant organisms (MDRO) and ESBL in LTCF, including transmission patterns, rates of infection, and factors associated with infections. It may be necessary to extend the requirements and precautions to MDRO and ESBL-producers.

Abstract
BACKGROUND The purpose of this study is to determine whether elderly subjects with severe brain atrophy, which is associated with neurodegeneration and difficulty swallowing (dysphagia), are more susceptible to lower respiratory tract infections (LRTI), including pneumonia. METHODS The severity of brain atrophy was assessed by computed tomography in 51 nursing home residents aged 60-96 years. The incidence of LRTI, defined by body temperature ≥ 38.0°C, presence of two or more respiratory symptoms, and use of antibiotics, was determined over 4 years. The incidence of LRTI was compared according to the severity and type of brain atrophy. RESULTS The incidence rate ratio of LRTI was significantly higher (odds ratio 4.60, 95% confidence interval 1.18-17.93, fully adjusted P = 0.028) and the time to the first episode of LRTI was significantly shorter (log-rank test, P = 0.019) in subjects with severe brain atrophy in any lobe. Frontal and parietal lobe atrophy was associated with a significantly increased risk of LRTI, while temporal lobe atrophy, ventricular dilatation, and diffuse white matter lesions did not influence the risk of LRTI. CONCLUSION Elderly subjects with severe brain atrophy are more susceptible to LRTI, possibly as a result of neurodegeneration causing dysphagia and silent aspiration. Assessing the severity of brain atrophy might be useful to identify subjects at increased risk of respiratory infections in a prospective manner.

Infection control: point prevalence study versus incidence study in Polish long-term care facilities in 2009-2010 in the Małopolska Region. Infection 2012; 41:1-8.

Abstract
OBJECTIVE The objective of this study was to evaluate the epidemiology of infection in Polish long-term care facilities (LTCFs) and to analyse the capabilities and legitimacy of implementing continuous targeted surveillance. METHODS The study investigated the relationship between the presence of infection and health status, tested using a point prevalence study (PPS) and incidence study. A 1-day PPS was carried out in October 2009, with prospective continuous surveillance between December 2009 and November 2010. Infections were defined according to McGeer's criteria. RESULTS The surveillance encompassed 193 people. The prevalence was 14.0 % in residential homes (RHs) and 18.7 % in the nursing home (NH). Various types of infections (in the PPS) were observed significantly more frequently in patients with asthma, wounds, atherosclerosis of lower extremities, tracheotomy tubes and conditions in patients hospitalised in intensive care units (ICUs) up to 1 year before the PPS day. The incidence rate was 2.7/1,000 patient days (pds). CONCLUSIONS The factors determined to be important for the risk of infection (in the continuous study) include the general status of patients, expressed using Barthel, abbreviated mental and Katz scales, as well as limited physical activity, stool incontinence and urinary catheterisation. In the PPS study, only a slight relationship was shown between the general status of residents and the risk of infection. None of the general status scales used clinically were shown to be helpful in estimating that risk, similarly to the five-point physical activity scale. Prospective continuous surveillance shows a possibility of limiting the range of infection control in the LTCFs within targeted surveillance in a population of patients that requires intensive nursing procedures. As a marker, one could point to the low score in the Barthel or Katz scales or low physical activity/bedridden persons.

Abstract
DESIGN We conducted a retrospective cohort study to examine the role played by length of hospital stay in the risk of healthcare-associated bloodstream infection (BSI), independent of demographic and clinical risk factors for BSI. PATIENTS We employed data from 113,893 admissions from inpatients discharged between 2006 and 2008. SETTING Large tertiary healthcare center in New York City. METHODS We estimated the crude and adjusted hazard of BSI by conducting logistic regression using a person-day data structure. The covariates included in the fully adjusted model included age, sex, Charlson score of comorbidity, renal failure, and malignancy as static variables and central venous catheterization, mechanical ventilation, and intensive care unit stay as time-varying variables. RESULTS In the crude model, we observed a nonlinear increasing hazard of BSI with increasing hospital stay. This trend was reduced to a constant hazard when fully adjusted for demographic and clinical risk factors for BSI. CONCLUSION The association between longer length of hospital stay and increased risk of infection can largely be explained by the increased duration of stay among those who have underlying morbidity and require invasive procedures. We should take caution in attributing the association between length of stay and BSI to a direct negative impact of the healthcare environment.

Abstract
BACKGROUND Urinary tract infections (UTI) are common among the oldest old and may lead to a few days of illness, delirium or even to death. We studied the incidence and predictive factors of UTI among the oldest old in the general population. METHODS The Leiden 85-plus Study is a population-based prospective follow-up study of 86-year-old subjects in Leiden, The Netherlands. Information on the diagnosis of UTI was obtained annually during four years of follow-up from the medical records and interviews of treating physicians. A total of 157 men and 322 women aged 86 years participated in the study. Possible predictive factors were collected at baseline, including history of UTI between the age of 85 and 86 years, aspects of functioning (cognitive impairment (Mini-Mental State Examination (MMSE) < 19), presence of depressive symptoms (Geriatric Depression Scale (GDS) > 4), disability in activities of daily living (ADL)), and co-morbidities. RESULTS The incidence of UTI from age 86 through 90 years was 11.2 (95% confidence interval (CI) 9.4, 13.1) per 100 person-years at risk. Multivariate analysis showed that history of UTI between the age of 85 and 86 years (hazard ratio (HR) 3.4 (95% CI 2.4, 5.0)), impaired cognitive function (HR 1.9 (95% CI 1.3, 2.9)), disability in daily living (HR 1.7 (95% CI 1.1, 2.5)) and urine incontinence (HR 1.5 (95% CI 1.0, 2.1)) were independent predictors of an increased incidence of UTI from age 86 onwards. CONCLUSIONS Within the oldest old, a history of UTI between the age of 85 and 86 years, cognitive impairment, ADL disability and urine incontinence are independent predictors of developing UTI. These predictive factors could be used to target preventive measures to the oldest old at high risk of UTI.

Abstract
INTRODUCTION Infection processes in gerontology centres (GC) are one of the main causes of mortality and aggravation of concomitant chronic diseases. An epidemiological surveillance system was set up to find out their magnitude and distribution. MATERIAL AND METHODS A prevalence study was conducted during the years 2006-2009 in 4 GCs of the Matia Foundation. Prevalence was measured by making an annual cut-off, recording: infection type, demographic data, risk factors and antibiotic use. The incidence was measured for two years in one GC as a pilot centre, recording: infection type and antibiotic use. RESULTS The prevalence in the GCs varied between 4.8% and 6.44%. The infection incidence density in the pilot study was between 3.45-5.77 infections per 1,000 resident days. The most common infection location and in this order were, respiratory, urinary and cutaneous. The incidence of respiratory infection is more statistically significant in the presence of dysphagia, malnutrition and COPD. However, no significant relationship was seen in the incidence of urinary infection with the different risk factors analysed. CONCLUSIONS The frequency and repercussions of nosocomial infections in GCs demonstrate the need for intervention plans and the development of adequate prevention measures.

Abstract
In this study we assessed the incidence and types of healthcare-associated infection (HCAI) in a nursing home resident population. The influences of home size, resident category, gender and age were also examined. Fifteen homes were recruited and infection rates recorded from 1 October 2006 to 2 December 2006. A rate of 6.04 infections/1000 bed days was recorded for the complete study. Infection rates for the four main categories of infection (number of infections/ 1000 bed days) were respiratory (2.52), urinary (1.87), skin and soft tissue (1.57) and gastrointestinal (0.41). Infection rates for small, medium and large homes were 4.64 (range 1.95—6.51), 5.9 (range 0.49—10.76) and 7.79 (range 5.79—9.39), respectively; however, statistical significance was not achieved ( p = 0.335). Results indicate that respiratory infection rates are higher in larger homes (4.08) than in small (1.88) or medium size homes (2.22). Urinary infection rates were similar in small (1.89), medium (1.88) and large (1.82) homes and skin and soft tissue infections were lower in small homes (0.87) but similar in medium (1.69) and large (1.90) homes. We found a statistically significant relationship between the type of infection acquired and both resident category ( p = 0.017) and gender ( p = 0.005); the relationship between type of infection and age did not reach statistical significance ( p = 0.346).

Abstract
SummaryThis review provides an update on current evidence surrounding epidemiology, treatment and prevention of lower respiratory tract infection, with special reference to pneumonia and influenza, in care home residents. The care home sector is growing and provides a unique ecological niche for infections, housing frail older people with multiple co-morbidities and frequent contact with healthcare services. There are therefore considerations in the epidemiology and management of these conditions that are specific to care homes. Opportunities for prevention, in the form of vaccination strategies and improving oral hygiene, may reduce the burden of these diseases in the future. Work is needed to research these infections specifically in the care home setting, and this article highlights current gaps in our knowledge.

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
The study assessed the impact on nursing home (NH) resident infection rates of providing staff with a personal alcohol-based hand product (ABHP) with and without training on its use. Fifteen North Wales NHs were recruited and randomly allocated into one of three groups. All monitored infection rates throughout the study period of 18 weeks (Phase I [weeks 1—9], Phase II [weeks 11—19]). NHs used liquid soap and water for hand washing throughout the study. Groups B and C introduced interventions during week ten: Group B were provided with personal ABHPs without training on use; Group C personal ABHPs with standard training from the sponsoring hand hygiene company. Infection rates between groups and pre- and post-intervention were compared. Infection rates (per 1,000 bed days) for Phase I vs. Phase II of the study were: Group A: 6.99 vs. 7.16; Group B: 6.08 vs. 3.46; and Group C: 5.04 vs. 6.78 respectively. Change in infection rates in Groups B and C pre- and post-intervention did not reach statistical significance, p = 0.097 and p = 0.072 respectively. Comparison of rates in non-intervention Group A with the intervention groups indicated a significantly lower rate after the intervention in Group B ( p = 0.035) but not Group C ( p = 0.765). Findings are limited due to sample size; introduction of personal ABHPs with training did not reduce infection rates. This conflicts with other studies examining education and improvement of hand hygiene compliance. However, infection rates fell in NHs not receiving training, possibly mediated through a sense of `ownership' of the intervention.

Abstract
The aim of this study was to identify the consequences of healthcare-associated infections in Norwegian nursing homes, to include debilitation, hospital transfer and mortality. We followed the residents of six nursing homes in two major cities in Norway during the period October 2004 to March 2005. For each resident with infection we randomly selected two controls among residents who did not have an infection. Cases and the controls were followed for 30 days as a cohort in order to measure the incidence of complications and risk ratio (RR) in the two groups. The incidence of infection was 5.2 per 1000 resident-days. After 30 days follow-up 10.9% of residents who had acquired infection demonstrated a reduction in overall physical condition compared with 4.8% in the unexposed group (RR: 2.3). Altogether 13.0% of residents with infections were admitted to hospital compared with 1.4% in the unexposed group (RR 9.2), and 16.1% residents with infections died in the nursing home during follow-up compared with 2.4% in the unexposed group (RR: 6.6). Residents with lower respiratory tract infections demonstrated higher morbidity and mortality. In conclusion, healthcare-associated infections cause severe consequences for people living in nursing homes, including debilitation, hospital admission and death.

Abstract
Within the last two decades risks posed by infectious diseases outside of hospitals and nursing homes had no high significance in the public perception. The home environment is regarded as a save shelter from infectious risks. In the mean time there have been dramatic socio-demographic, health policy and technological changes which have increased infectious risks outside medical facilities. In Germany up to 1.4 million people with multiple morbidities are nursed at home. Technological changes with the aim to protect the environment, like reduction of water temperature and water volumes in washing processes has lowered the efficacy to control pathogens. Thus it is time to revise the process of risk assessment in which not only aspects of environmental protection but also those of health protection must be taken into account. The article gives an overview of new risks and epidemiological changes and discusses the necessity of a new risk assessment and risk management approach which hopefully will lead to a changing paradigm.

Abstract
The S3 guidelines for diagnosis and therapy use German epidemiological data to set the standards for a risk and degree of severity based treatment of community acquired pneumonia (CAP). Over the last few years, a change in pathogen epidemiology has been recognized with the significance of staphylococci and enterobacteria increasing. CAP is becoming increasingly a disease of the elderly, for whom a more broadly effective initial therapy appears to be needed. Resistant pathogens play an important role in the course of the disease. For patients with a low risk of mortality, a reduction in the length of therapy seems possible. On the other hand, the early identification of critically ill patients who require treatment with high dose, broad spectrum antibiotics is necessary. Antibiotic associated diarrhoea, caused by Clostridium difficile, is a significant complication in antibiotic therapy. With the introduction of vaccination against Streptococcus pneumoniae for children, a change in the course of the illness and an improvement in the resistance situation has been achieved. An update of the S3 guidelines is intended for 2008 in order to integrate new knowledge into the recommendations.
