A pragmatic cluster randomised controlled trial of air filtration to prevent symptomatic winter respiratory infections (including COVID-19) in care homes (AFRI-c) in England: Trial protocol. PLoS One 2024; 19:e0304488. [PMID: 39042618 PMCID: PMC11265654 DOI: 10.1371/journal.pone.0304488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 05/07/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND Respiratory tract infections are readily transmitted in care homes. Airborne transmission of pathogens causing respiratory tract illness is largely unmitigated. Portable high-efficiency-particulate-air (HEPA) filtration units capture microbial particles from the air, but it is unclear whether this is sufficient to reduce infections in care home residents. The Air Filtration to prevent symptomatic winter Respiratory Infections (including COVID-19) in care homes (AFRI-c) randomized controlled trial will determine whether using HEPA filtration units reduces respiratory infection episodes in care home residents. METHODS AFRI-c is a cluster randomized controlled trial that will be delivered in residential care homes for older people in England. Ninety-one care homes will be randomised to take part for one winter period. The intervention care homes will receive HEPA filtration units for use in communal areas and private bedrooms. Normal infection control measures will continue in all care homes. Anonymised daily data on symptoms will be collected for up to 30 residents. Ten to 12 of these residents will be invited to consent to a primary care medical notes review and (in intervention homes) to having an air filter switched on in their private room. The primary outcome will be number of symptomatic winter respiratory infection episodes. Secondary outcomes include specific clinical measures of infection, number of falls / near falls, number of laboratory confirmed infections, hospitalisations, staff sickness and cost-effectiveness. A mixed methods process evaluation will assess intervention acceptability and implementation. DISCUSSION The results of AFRI-c will provide vital information about whether portable HEPA filtration units reduce symptomatic winter respiratory infections in older care home residents. Findings about effectiveness, fidelity, acceptability and cost-effectiveness will support stakeholders to determine the use of HEPA filtration units as part of infection control policies.

Tingström P, Karlsson N, Grodzinsky E, Sund Levander M. The value of fever assessment in addition to the Early Detection Infection Scale (EDIS). A validation study in nursing home residents in Sweden. BMC Geriatr 2023; 23:585. [PMID: 37737163 PMCID: PMC10515033 DOI: 10.1186/s12877-023-04266-6] [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: 10/26/2022] [Accepted: 08/30/2023] [Indexed: 09/23/2023] Open
Abstract
BACKGROUND In order to improve detection of suspected infections in frail elderly there is an urgent need for development of decision support tools, that can be used in the daily work of all healthcare professionals for assessing non-specific and specific changes. The aim was to study non-specific signs and symptoms and fever temperature for early detection of ongoing infection in frail elderly, and how these correlates to provide the instrument, the Early Detection Infection Scale (EDIS), which is used to assess changes in health condition in frail elderly. METHODS This was an explorative, prospective cohort study, including 45 nursing home residents, 76 to 99 years, in Sweden. Nursing assistants measured morning ear body temperature twice a week and used the EDIS to assess individual health condition daily for six months. The outcome comprised events of suspected infection, compiled from nursing and medical patient records. Factor analysis and multivariate logistic regression analysis were performed to analyse data. RESULTS Fifteen residents were diagnosed with at least one infection during the six-month follow-up and 189 observations related to 72 events of suspected infection were recorded. The first factor analysis revealed that the components, change in cognitive and physical function, general signs and symptoms of illness, increased tenderness, change in eye expression and food intake and change in emotions explained 61% of the variance. The second factor analysis, adding temperature assessed as fever to > 1.0 °C from individual normal, resulted in change in physical function and food intake, confusion and signs and symptoms from respiratory and urinary tract, general signs and symptoms of illness and fever and increased tenderness, explaining 59% of the variance. In the first regression analysis, increased tenderness and change in eye expression and food intake, and in the second change in physical function and food intake, general signs and symptoms of illness and fever (> 1.0 °C from individual normal) and increased tenderness were significantly associated with increased risk for ongoing infection. CONCLUSION No items in the EDIS should be removed at present, and assessment of fever as > 1.0 °C from individual normal is a valuable addition. The EDIS has the potential to make it easier for first line caregivers to systematically assess changes in health condition in fragile elderly people and helps observations to be communicated in a standardised way throughout the care process. The EDIS thus contributes to ensuring that the decisions not being taken at the wrong level of care.

Functional Decline in COVID-19 Older Survivors Compared to Other Pneumonia Patients, a Case Control Study. J Nutr Health Aging 2022; 26:896-903. [PMID: 36156682 PMCID: PMC9470507 DOI: 10.1007/s12603-022-1845-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 07/15/2022] [Indexed: 10/27/2022]
Abstract
OBJECTIVES Among patients over 75 years, little is known about functional decline due to COVID-19. The aim of this study was to explore this functional decline, compare to other infectious pneumonia. DESIGN AND SETTING This case-control study included all COVID-19 patients hospitalized from March to December 2020 in Acute Geriatric Ward in Nantes University Hospital matched 1/1 with patients with pneumonia hospitalized in geriatric department between March 2017 and March 2019 (controls) on sex, age. Functional decline was assessed at 3 month follow up as it is routinely done after hospitalization in geriatric ward. We performed multivariable analyses to compare clinical outcomes between patients with COVID-19 vs controls. RESULTS 132 pairs were matched on age (mean: 87 y-o), and sex (61% of women). In multivariable logistic regression analysis, there were no statistical significant association between COVID-19 infection and functional decline (OR=0.89 p=0.72). A statistical significant association was found between functional decline and Charlson comorbidity index (OR=1.17, p=0.039); prior fall (OR=2.08, p=0.012); malnutrition (OR=1.97, p=0.018); length of hospital stay (OR=1.05, p=0.002) and preadmission ADL(OR=1.25, p=0.049). CONCLUSION COVID-19 does not seem to be responsible for a more frequent or severe functional decline than other infectious pneumonia in older and comorbid population after 3 month follow up. In this population, pneumonia is associated with functional decline in almost 1 in 2 cases. The individual preadmission frailty seems to be a more important predictor of functional decline, encouraging multidimensional care management for this population.

Diagnosis, Treatment, and Prevention of Urinary Tract Infections in Post-Acute and Long-Term Care Settings: A Consensus Statement From AMDA's Infection Advisory Subcommittee. J Am Med Dir Assoc 2021; 21:12-24.e2. [PMID: 31888862 DOI: 10.1016/j.jamda.2019.11.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 11/06/2019] [Accepted: 11/10/2019] [Indexed: 02/04/2023]
Abstract
The diagnosis and management of urinary tract infections (UTIs) among residents of post-acute and long-term care (PALTC) settings remains challenging. Nonspecific symptoms, complex medical conditions, insufficient awareness of diagnostic criteria, and unnecessary urine studies all contribute to the inappropriate diagnosis and treatment of UTIs in PALTC residents. In 2017, the Infection Advisory Subcommittee at AMDA-The Society for Post-Acute and Long-Term Care Medicine convened a workgroup comprised of experts in geriatrics and infectious diseases to review recent literature regarding UTIs in the PALTC population. The workgroup used evidence as well as their collective clinical expertise to develop this consensus statement with the goal of providing comprehensive guidance on the diagnosis, treatment, and prevention of UTIs in PALTC residents. The recommendations acknowledge limitations inherent to providing medical care for frail older adults, practicing within a resource limited setting, and prevention strategies tailored to PALTC populations. In addition, the consensus statement encourages integrating antibiotic stewardship principles into the policies and procedures used by PALTC nursing staff and by prescribing clinicians as they care for residents with a suspected UTI.

Risk adjustment for benchmarking nursing home infection surveillance data: A narrative review. Am J Infect Control 2021; 49:366-374.

Abstract
Until recently, there was no national surveillance system for monitoring infection occurrence in long-term care facilities (LTCF) in the United States. As a result, there are no national benchmarks for LTCF infection rates that can be utilized for quality improvement at the facility level. One of the major challenges in the reporting of health care-related infection data is accounting for nonmodifiable facility and patient characteristics that influence benchmarks for infection. The objectives of this paper are to review: (a) published infection rates in LTCF in the United States to assess the level of variability; (b) studies describing facility- and resident-level risk factors for infection that can be used in risk adjustment models; (c) published attempts to risk-adjust LTCF infection rates; and (d) efforts to develop models specifically for risk adjustment of infection rates in LTCF for benchmarking. It is anticipated that this review will stimulate further study of methods to risk-adjust LTCF infection rates for benchmarking that will facilitate research and public reporting.

Abstract
The incidence of infections increases with age and results in a higher risk of morbidity and mortality. This rise is not mainly related to chronological age per se but has been linked mostly to individual factors such as immunosenescence; the presence of comorbidities; the occurrence of geriatric syndromes such as poor nutrition, polypharmacy, and cognitive disorders; and the presence of functional impairment concomitant with environmental, healthcare-related and microbiological factors such as the increasing risk of multidrug-resistant microorganisms. The geriatric concept of frailty introduces a new approach for considering the risk of infection; this concept highlights the importance of functional status and is a more comprehensive and multicomponent approach that may help to reverse the vulnerability to stress. The aim of this article is to provide some typical hallmarks of infections among older adults in comparison to younger individuals. The main differences among the older population that are presented are an increased prevalence of infections and potential risk factors, a higher risk of carrying multidrug-resistant microorganisms, an increase in barriers to a prompt diagnosis related to atypical presentations and challenges with diagnostic tools, a higher risk of under- and over-diagnosis, a worse prognosis with a higher risk of acute and chronic complications and a particular need for better communication among all healthcare sectors as they are closely linked together.

Abstract
Antibiotics are among the most common medications prescribed in nursing homes. The annual prevalence of antibiotic use in residents of nursing homes ranges from 47% to 79%, and more than half of antibiotic courses initiated in nursing-home settings are unnecessary or prescribed inappropriately (wrong drug, dose, or duration). Inappropriate antibiotic use is associated with a variety of negative consequences including Clostridioides difficile infection (CDI), adverse drug effects, drug-drug interactions, and antimicrobial resistance. In response to this problem, public health authorities have called for efforts to improve the quality of antibiotic prescribing in nursing homes.

A global agenda for older adult immunization in the COVID-19 era: A roadmap for action. Vaccine 2020; 39:5240-5250.

Abstract
Given our global interconnectedness, the COVID-19 pandemic highlights the urgency of building a global system that can support both routine and pandemic/epidemic adult immunization. As such, a framework to recommend vaccines and build robust platforms to deliver them to protect the rapidly expanding demographic of older adults is needed. Adult immunization as a strategy has the broad potential to preserve and improve medical, social, and economic outcomes, including maintaining functional ability that benefits older adults, their families, communities, and countries. While we will soon have multiple vaccines against COVID-19, we must recognize that we already have a variety of vaccines against other pathogens that can keep adults healthier. They can prevent simultaneous co-infection with COVID-19, and may favorably impact- the outcome of a COVID-19 illness. Further, administering a vaccine against COVID-19 requires planning now to determine delivery strategies impacting how older adults will be immunized in a timely manner. A group of international experts with various backgrounds from health and aging disciplines met to discuss the evidence case for adult immunization and crucial knowledge gaps that must be filled in order to implement effective policies and programs for older adult immunization. This group, coming together as the International Council on Adult Immunization (ICAI), outlined a high-level roadmap to catalyze action, provide policy guidance, and envision a global adult immunization platform that can be adapted by countries to fit their local contexts. Further meetings centered around the value of adult immunization, particularly in the context of COVID-19. There was agreement that programs to deliver existing influenza, pneumococcal, herpes zoster vaccines, and future COVID-19 vaccines to over a billion older adults who are at substantially higher risk of death and disability due to vaccine-preventable diseases are more urgent than ever before. Here we present a proposed framework for delivering routine and pandemic vaccines. We call upon the global community and governments to prioritize action for integrating robust adult immunization programs into the public health agenda.

Abstract
AIMS To assess associations of comorbidity patterns observed in people living with HIV (PLWH) with risk factors and health outcomes. METHODS Common patters of comorbidities in PLWH participating in the Pharmacokinetic and Clinical Observations in People Over Fifty study were determined using principal component analysis and a severity score for each pattern was derived. Associations between each pattern's severity score and risk factors were assessed using median regression. The independent associations of patterns' severity scores with self-reported physical and mental health (SF-36 summary scores) were assessed using linear regression, with functional impairment (Lawton IADL < 8) and hospitalization in last year using logistic regression and with number of general practitioner visits using Poisson regression. RESULTS A total of 1073 PLWH were analysed: 85.2% male, median (interquartile range) age 52 (47-59) years, 98% on therapy. Duration of HIV was associated with higher severity in 4/6 of patterns: cardiovascular diseases, mental health problems, metabolic disorders and chest/other infections (all P ≤ 0.001). Prior AIDS was associated with higher severity scores for the same patterns and for the pattern of cancers (P < 0.001). The pattern of cardiovascular diseases was associated with poorer physical health (P = 0.02), higher risk of functional impairment (P = 0.02) and hospitalization (P < 0.001) and with higher number of general practitioner visits (P < 0.001). Severity of mental health (all P < 0.001) and of chest/other infections patterns negatively affected all the five health outcomes. CONCLUSION Common patterns of comorbidities seen in PLWH appear to have different risk factors and to differently affect health outcomes. These findings may assist the development of targeted intervention to prevent, treat and manage the increasingly prevalent multimorbidity in PLWH.

Abstract
OBJECTIVES The objective of this study is to describe antibacterial use in long-term care facilities and to investigate the determinants of use. DESIGN This study is a quality improvement study conducted from January 2011 to December 2016. SETTING Long-term care facilities in the canton of Vaud, Western Switzerland, were investigated. PARTICIPANTS Twenty-three long-term care facilities were included in this study. INTERVENTION The intervention included the publication of local guidelines on empirical antibacterial therapy and the implementation of physician-pharmacist-nurse quality circles. MEASURES The main outcome was antibacterial use, expressed as defined daily doses (DDD) per 1000 beds per day. Statistical analyses were performed through a 1-level mixed model for repeated measurements. RESULTS Antibacterial use decreased from 45.6 to 35.5 DDD per 1000 beds per day (-22%, P < .01) over the 6-year study period, which was mostly explained by reduced fluoroquinolone use (-59%, P < .001). A decrease in range of use among LTCFs was observed during the study period, and 27% of antibacterial use was related to the WATCH group (antibiotics with higher toxicity concerns and/or resistance potential) according to the AWaRe categorization of the WHO, decreasing from 17.3 DDD per 1000 beds per day to 9.5 (-45%) over the study period. The use of antibacterials from the RESERVE group ("last-resort" treatment options) was very low. CONCLUSION AND IMPLICATIONS A reduction in facility-level antibacterial use and in variability across LTCFs was observed over the study period. The dissemination of empirical antibacterial prescription guidelines and the implementation of physician-pharmacist-nurse quality circles in all LTCFs of the canton of Vaud likely contributed to this reduction. Antibacterials from the WATCH group still represented 27% of the total use, providing targets for future antibiotic stewardship activities.

Influenza Other Respir Viruses 2019; 13:391-397. [PMID: 30848082 PMCID: PMC6586187 DOI: 10.1111/irv.12638] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 01/30/2019] [Accepted: 02/02/2019] [Indexed: 12/19/2022] Open
Abstract
Background Frailty is associated with increased risk of mortality and decline in functional status among older adults. Older adults are at increased risk of severe disease from acute respiratory illness (ARIs), but ARI effects on frailty status among older adults are not well understood. We evaluated how ARIs affect short‐term frailty status among community‐dwelling adults aged ≥65 years in Nakhon Phanom, Thailand. Methods During May 2015 to May 2017, older adults were contacted weekly to identify ARIs as part of a community‐based longitudinal cohort study. Each participant's frailty status was assessed at baseline and every 6 months using the Vulnerable Elders Survey‐13 (VES‐13). We selected cohort participants with an ARI and compared them with a sample of participants without an ARI matched on age, sex, influenza vaccination status, and most recent VES‐13 score. For these matched cohort members, an additional VES‐13 was recorded at 3‐4 weeks after the ARI episode date. Results Of 3220 cohort study participants, 114 participants with an ARI and 111 comparison participants without an ARI were selected for the matched cohort; three comparison participants were matched to two ARI cases. We found no statistically significant difference between ARI and non‐ARI participants in modified VES‐13 score 3‐4 weeks post‐episode (cases = 0.90, controls = 0.63, P = 0.07). Only two ARI episodes required hospitalization. Conclusions Primarily mild ARIs did not affect short‐term frailty status among community‐dwelling older adults in Thailand. As few cases of severe ARI were detected, the contribution of severe ARI to changes in frailty requires further investigation.

Abstract
OBJECTIVES Populations are aging worldwide. This paper summarizes some of the challenges and opportunities due to the increasing burden of infectious diseases in an aging population. RESULTS Older adults typically suffer elevated morbidity from infectious disease, leading to increased demand for healthcare resources and higher healthcare costs. Preventive medicine, including vaccination can potentially play a major role in preserving the health and independence of older adults. However, this potential of widespread vaccination is rarely realized. Here, we give a brief overview of the problem, discuss concrete obstacles and the potential for expanded vaccination programs to promote healthy aging. CONCLUSION The increasing healthcare burden of infectious diseases expected in aging populations could, to a large extent, be reduced by achieving higher vaccination coverage among older adults. Vaccination can thus contribute to healthy aging, alongside healthy diet and physical exercise. The available evidence indicates that dedicated programs can achieve substantial improvements in vaccination coverage among older adults, but more research is required to assess the generalizability of the results achieved by specific interventions (see Additional file 1).

Abstract
OBJECTIVE Immune challenges result in sickness responses such as decreased activity, fever, and spatial learning deficits. While these responses occur simultaneously, they are not usually evaluated concurrently or for an extended time. The purpose of this study was to examine how an immune challenge affected activity and temperature responses in animals tested concurrently in the Morris water maze (MWM) over 5 days and how aging interacts with such responses. METHOD An accepted model of aging, adult ( n = 10; 5-6 months) and aged ( n = 7; 22 months) male Brown-Norway rats were implanted with a telemetry device (Mini Mitter, Oakmont, PA) to continuously monitor temperature and activity following an immune challenge. These animals were injected with either 250 μg/kg lipopolysaccharide (LPS) or 0.9% sodium chloride and then assessed in the MWM for 5 days. RESULTS Temperature responses varied by age. Initial temperatures decreased in both experimental groups followed by an increase (fever) in the adult group, while the temperatures of the aged animals remained decreased. Although both age groups were sedentary at baseline, activity decreased after LPS only in the adult group. CONCLUSION An LPS immune challenge resulted in age-dependent temperature and activity changes. There was an absence of fever and no effect on activity in aged LPS-treated animals. These results may suggest the need to assess a broader spectrum of sickness responses when monitoring elderly individuals for infection and not rely on the presence of fever. Activity may not be a sensitive indicator of sickness in some aging models.

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
Sickness behaviors, adaptive responses to infections, include lethargy, depression, reduced eating and grooming, and concentration problems resulting from interactions between the immune and neuroendocrine systems. Detecting these responses is especially critical in the elderly, as the infections that cause them can lead to cognitive impairment. While deficits in spatial learning, a hippocampal-dependent form of learning, are part of the sickness response, directional heading errors (DHEs; an indicator of spatial-learning deficits) and their time trajectories need further examination. Therefore, we simultaneously investigated the time trajectory of age-dependent sickness responses and spatial learning over 5 days in adult (5-6 months) and aged (22 months) male Brown-Norway rats injected with 250 μg/kg lipopolysaccharide (LPS; experimental group) or 0.9% sodium chloride (control group). LPS administration resulted in pronounced, age-dependent weight loss and decreased food intake that persisted in the aged group. Animals were tested for 5 days (trial) in the Morris water maze. After 7 days of rest, animals were retested for 2 days (retention). Adult and aged LPS-treated animals displayed greater differences in mean DHE than the control groups, indicating that they exhibited more DHE over the trial days. Experimental groups did not show consistent DHE improvement until Day 4 (adult) or 5 (aged). LPS had no effect on probe or retention trials. We conclude that LPS activation of the immune system results in a selective, age-dependent impairment in spatial learning, decreased food intake, and weight loss. All of these results are prolonged in aged animals.

Abstract
OBJECTIVES This study investigated the prevalence of multidrug-resistant organisms (MDROs) in the residents and environments of long-term care facilities (LTCFs) in Taiwan. METHODS We prospectively investigated the distribution of MDROs in residents of six LTCFs and their environments from January 2015 to December 2015 (intervention period). Active surveillance of colonization of MDROs was performed by culturing rectal and nasal swab samples every 3 months for the residents: 63, 79, and 73 in the first, second, and third surveillance investigations, respectively. If MDROs, including methicillin-resistant Staphylococcus aureus, carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Pseudomonas aeruginosa, and MDR Acinetobacter baumannii were identified, then swab specimens from environmental sources were also collected and cultured. During the study period, several infection control measures were also implemented. RESULTS The overall infection density decreased significantly from 2.69 per 1000 patient-days in the preintervention (January 2014 to December 2014) to 2.39 per 1000 patient-days during the intervention period (p < 0.001). A total of 154 samples from residents and environmental sources were positive for MDROs. Methicillin-resistant S. aureus (n = 83, 53.9%) was the predominant organism, followed by carbapenem-resistant Enterobacteriaceae (n = 35, 22.7%), MDR A. baumannii (n = 30, 19.5%), and carbapenem-resistant P. aeruginosa (n = 6, 3.9%). The rates of detection of MDROs were 27.9% (60/215) in nasal swabs, 15.8% (34/215) in rectal swabs, and 11.1% (60/542) in the environmental sources. CONCLUSIONS The distribution and persistence of MDROs varied among the different LTCFs and time periods.

Abstract
An antimicrobial stewardship program (ASP) has been recommended for long-term care facilities because of the increasing problem of antibiotic resistance in this setting to improve prescribing and decrease adverse events. Recommendations have been made for the components of such a program, but there is little evidence to support any specific methodology at the present time. The recommendations make minimal reference to metrics, an essential component of any ASP, to monitor the results of interventions. This article focuses on the role of antibiotic use metrics as part of an ASP for long-term care. Studies specifically focused on development of antibiotic use metrics for long-term care are reviewed. It is stressed that these metrics should be considered as an integral part of an ASP in long-term care. In order to develop benchmarks for antibiotic use for long-term care, there must be appropriate risk adjustment for interfacility comparisons and quality improvement. Studies that have focused on resident functional status as a risk factor for infection and antibiotic use are reviewed. Recommendations for the potentially most useful and feasible metrics for long-term care are provided along with recommendations for future research.

Abstract
Herpes zoster is a frequent painful infectious disease whose incidence and severity increase with age. In older people, there is a strong bidirectional link between herpes zoster and functional decline, which refers to a decrement in ability to perform activities of daily living due to ageing and disabilities. However, the exact nature of such link remains poorly established. Based on the opinion from a multidisciplinary group of experts, we here propose a new model to account for the interplay between infection, somatic/psychiatric comorbidity, coping skills, polypharmacy, and age, which may account for the functional decline related to herpes zoster in older patients. This model integrates the risk of decompensation of underlying disease; the risk of pain becoming chronic (e.g. postherpetic neuralgia); the risk of herpes zoster non-pain complications; the detrimental impact of herpes zoster on quality of life, functioning, and mood; the therapeutic difficulties due to multimorbidity, polypharmacy, and ageing; and the role of stressful life events in the infection itself and comorbid depression. This model underlines the importance of early treatment, strengthening coping, and vaccine prevention.

Abstract
Vaccine biomarkers are critical to many aspects of vaccine development and licensure, including bridging findings in pre-clinical studies to clinical studies, predicting potential adverse events, and predicting vaccine efficacy. Despite advances in our understanding of various biological pathways, and advances in systems analyses of the immune response, there remains much to learn about qualitative and quantitative aspects of the human host response to vaccination. To stimulate discussion and identify opportunities for collaborative ways to advance the field of vaccine biomarkers, A Next Generation Vaccine Biomarker workshop was held in Ottawa. The two day workshop, sponsored by the National Research Council Canada, Canadian Institutes of Health Research, Public Health Agency of Canada, Pfizer, and Medicago, brought together stakeholders from Canadian and international industry, government and academia. The workshop was grouped in themes, covering vaccine biomarker challenges in the pre-clinical and clinical spaces, veterinary vaccines, regulatory challenges, and development of biomarkers for adjuvants and cancer vaccines. The use of case studies allowed participants to identify the needs and gaps requiring innovation. The workshop concluded with a discussion on opportunities for vaccine biomarker discovery, the Canadian context, and approaches for moving forward. This article provides a synopsis of these discussions and identifies steps forward for advancing vaccine biomarker research in Canada.

Abstract
INTRODUCTION This study investigated the effects of recurrent urinary tract infections (rUTI) and the impact of prophylaxis on rUTI and patients' quality of life (QoL). METHODS Altogether, 575 patients affected by rUTI were included in a 6-month observational study. QoL was assessed using the Hospital Anxiety and Depression (HAD) and the Leicester scales. Statistical analyses were performed using SAS® Version 8.2 software (SAS Institute Inc., Cary, NC, USA). The significance level was set at 5%. Spearman correlation was used to assess the degree of correlation between infectious episodes and HAD and Leicester scores. For each parameter, the comparison between Day 0 and Day 180 was performed using Wilcoxon signed-rank test for quantitative data. RESULTS In total, 61.9% of patients suffering from rUTI exhibited some degree of depression at baseline (Day 0). Alternative oral non-antimicrobial prophylactic treatment for rUTI [Escherichia coli lyophilized bacterial lysate (OM-89)] was administered to 94.4% of patients (1 capsule a day for 90 days), followed by a 3-month treatment-free period. At the end of the study (Day 180), the mean number of UTI decreased by 59.3% (P ≤ 0.0001), the total HAD score decreased by 32.1% (P ≤ 0.0001), and the mean Leicester score decreased by 44.0% (P ≤ 0.0001) from baseline. There was a correlation trend between the reduction in the numbers of UTI at the end of the study compared to the 6 months prior to study entry and the reduction in the anxiety, depression, total HAD scores, activity, feeling, and total Leicester scores registered from Day 0 to Day 180, suggesting a lessening of emotional problems, and social and functional handicaps with decreasing UTI incidence. CONCLUSIONS This study showed that rUTI had a negative impact on patients' QoL and that effective alternative prophylaxis significantly improved their QoL.

Abstract
Pneumonia is one of the main causes of morbidity and mortality in the elderly. The elderly population has exponentially increased in the last decades and the current epidemiological trends indicate that it is expected to further increase. Therefore, recognizing the special needs of older people is of paramount importance. In this review we address the main differences between elderly and adult patients with pneumonia. We focus on several aspects, including the atypical clinical presentation of pneumonia in the elderly, the methods to assess severity of illness, the appropriate setting of care, and the management of comorbidities. We also discuss how to approach the common complications of severe pneumonia, including acute respiratory failure and severe sepsis. Moreover, we debate whether or not elderly patients are at higher risk of infection due to multi-drug resistant pathogens and which risk factors should be considered when choosing the antibiotic therapy. We highlight the differences in the definition of clinical stability and treatment failure between adults and elderly patients. Finally, we review the main outcomes, preventive and supportive measures to be considered in elderly patients with pneumonia.

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
OBJECTIVES A national survey was conducted to determine the prevalence and risk factors of methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum β-lactamases-producing Enterobacteriaceae (ESBLE) and vancomycin-resistant enterococci (VRE) among nursing home residents in Belgium. METHODS A random stratified, national prevalence survey was conducted in nursing home residents who were screened for carriage of ESBLE, MRSA and VRE by multisite enriched culture. Characteristics of nursing homes and residents were collected by a questionnaire survey and were analysed by multilevel logistic regression analysis. RESULTS Of 2791 screened residents in 60 participating nursing home, the weighted prevalence of ESBLE and MRSA carriage were 6.2% (range: 0 to 20%) and 12.2% (range: 0 to 36%), respectively. No cases of VRE were found. No relationship was found between ESBLE and MRSA prevalence rates within nursing homes and the rate of co-colonization was very low (0.8%). Geographical variations in prevalence of MRSA and ESBLE and in distribution of ESBL types in nursing home residents paralleled that of acute hospitals. Risk factors of ESBLE carriage included previously known ESBLE carriage, male gender, a low level of mobility and previous antibiotic exposure. Risk factors for MRSA colonization were: previously known MRSA carriage, skin lesions, a low functional status and antacid use. CONCLUSIONS A low prevalence of ESBLE carriage was found in nursing home residents in Belgium. The prevalence of MRSA carriage decreased substantially in comparison to a similar survey conducted in 2005. A low functional status appeared as a common factor for ESBLE and MRSA carriage. Previous exposure to antibiotics was a strong predictor of ESBLE colonization while increased clustering of MRSA carriage suggested the importance of cross-transmission within nursing homes for this organism. These results emphasize the need for global coordination of the surveillance of MDRO within and between nursing homes and hospitals.

Videcnik Zorman J, Lusa L, Strle F, Maraspin V. Bacterial infection in elderly nursing home and community-based patients: a prospective cohort study. Infection 2013; 41:909-16.

Abstract
PURPOSE The aim of the study was to assess differences between elderly nursing home (NH) residents and elderly patients living in the community admitted to hospital for bacterial infection. METHODS We conducted a prospective cohort study with manual data collection. Patients aged 65 years and older from NHs and from the community admitted to hospital for bacterial infection were included in the study. Patient characteristics, site of infection, microorganism profile, and final outcome were assessed and compared between these two subgroups of patients. RESULTS Two hundred and sixty-two patients were from NHs and 707 were from the community. Patients from NHs were older, had more underlying chronic illnesses, and more often showed characteristics indicating advanced debility. In both groups, the most common site of infection was the respiratory tract. In comparison to the community group, patients from NHs had a higher fatality rate (23.3 vs. 10.9%) and more often experienced functional decline at discharge (27.5 vs. 16.8%). After adjustment for age, sex, presence of comorbidity, and debility, NH residence remained associated with increased in-hospital mortality but not with functional decline. CONCLUSIONS Elderly patients from NHs admitted to hospital for bacterial infection are older and more debilitated than their counterparts from the community. Microorganisms found in the NH residents are somewhat different from those in the community dwellers. The community dwellers had a better survival rate than those admitted from the NHs after adjusting for age, sex, presence of any comorbidity, and debility.

Abstract
OBJECTIVE To assess the role of functional status as a risk factor for nosocomial infections in the elderly. DESIGN Prospective study. SETTING Acute care for elders units of university hospital of Grenoble. PARTICIPANT All patients over 75 years old consecutively hospitalized between January and April 2007. MEASUREMENT The main judgement criteria was the rate of nosocomial infection during the hospital stay, defined according to the French technical comity against nosocomial infections. Other data included functional status at baseline and admission (Katz' ADL), usual risk factors for nosocomial infections, demographic and geriatric assessment data. RESULTS The study included 223 patients. The mean age was 86.7±6.5 years. A nosocomial infection was diagnosed for 17.0% of the patients. In univariate analysis, the number of medicines, pressure sore, pneumonia diagnosis, illness severity, indwelling bladder catheter, IADL at baseline, and all disability parameters (ADL at baseline, ADL at admission, recent functional decline) were significantly associated with nosocomial infection (p<0.05). In multivariate analysis considering functional status at admission, indwelling bladder catheter (OR=4.43), severe disability at admission (OR=4.42) and illness severity (OR=2.68) were independently associated with nosocomial infection (p<0.05). In a second analysis considering functional status at baseline, only disability at baseline was independently associated with the onset of a nosocomial infection (OR=2.21). CONCLUSION Our results suggest a significant impact of functional impairment on the incidence of nosocomial infections in hospitalized elderly population. Disability is a higher risk factor for nosocomial infections than the usual and well-known other parameters. Larger prospective studies are needed to examine the power of this relationship.

Abstract
Background We assessed the association between activities of daily living (ADL) and mortality among nursing home residents in Japan. Methods This 1-year prospective cohort study investigated 8902 elderly adults in 140 nursing homes. Baseline measurements included age, sex, height, weight, body mass index (BMI), ADL, and dementia level. ADL levels were obtained by caregivers, using the Barthel Index (BI), after which total BI scores were calculated (higher scores indicate less dependence). Information on dates of discharge and mortality was also obtained to calculate person-years. The Cox proportional hazards model was used to estimate hazard ratios (HRs). Results Mean age was 84.3 years, and mean total BI score was 38.5. The HRs of mortality adjusted for sex, age, BMI, and type of nursing home were 7.6 (95% CI: 3.3–17.8) for those with a BI score of 0 (totally dependent), 3.9 (1.7–9.0) for those with a score of 1 to 10, 3.5 (1.4–8.7) for those with a score of 11 to 40, 2.7 (1.4–5.1) for those with a score of 41 to 70, and 1.3 (0.7–2.4) for those with a score of 71 to 99 (P for trend <0.001), as compared with those with a score of 100. Multivariate analysis revealed that BI, sex, age, and BMI were significantly associated with mortality rate. Conclusions There was a clear inverse association between ADL level and mortality. In conjunction with other risk factors, ADL level might effectively predict short-term mortality in institutionalized elderly adults.

Abstract
OBJECTIVES To examine the relationship between influenza and activity of daily living (ADL) decline and other clinical indicators in nursing home (NH) residents. DESIGN Retrospective NH-aggregated longitudinal study. SETTING Two thousand three hundred fifty-one NHs in 122 U.S. cities from 1999 to 2005. PARTICIPANTS Long-stay (>90 days) NH residents. MEASUREMENTS Quarterly city-level influenza mortality and state-level influenza severity. Quarterly incidence of Minimum Data Set-derived ADL decline (≥ 4 points), weight loss, new or worsening pressure ulcers (PUs), and infections. Outcome variables chosen as clinical controls were antipsychotic use, restraint use, and persistent pain. RESULTS City-level influenza mortality and state-level influenza severity were associated with higher rates of large (≥ 4 points) ADL decline (mortality β = 0.20, P < .001; severity β = 0.18, P < .001), weight loss (β = 0.19, P < .001; β = 0.24, P < .001), worsening PUs (β = 0.04, P = .08; β = 0.12, P < .001), and infections (β = 0.41, P < .001; β = 0.47, P < .001) but not with restraint use, antipsychotic use, or persistent pain. NH influenza vaccination rates were weakly associated with the outcomes (e.g., β = -0.009, P = .03 for ADL decline, β = 0.008, P = .07 for infections). Compared with the summer quarter of lowest influenza activity, the results for the other quarters translate to an additional 12,284 NH residents experiencing large ADL decline annually, 15,168 experiencing significant weight loss, 6,284 new or worsening PUs, and 29,753 experiencing infections due to influenza. CONCLUSION The results suggest a substantial and potentially costly effect of influenza on NH residents. The effect of influenza vaccination on preventing further ADL decline and other clinical outcomes in NH residents should be studied further.

A short-term, multicomponent infection control program in nursing homes: a cluster randomized controlled trial. J Am Med Dir Assoc 2012; 13:569.e9-17.

Abstract
OBJECTIVES To assess the impact of a hygiene-encouragement program on reducing infection rates (primary end point) by 5%. DESIGN A cluster randomized study was carried out over a 5-month period. SETTINGS AND PARTICIPANTS Fifty nursing homes (NHs) with 4345 beds in France were randomly assigned by stratified-block randomization to either a multicomponent intervention (25 NHs) or an assessment only (25 NHs). INTERVENTION The multicomponent intervention was targeted to caregivers and consisted of implementing a bundle of infection prevention consensual measures. Interactive educational meetings using a slideshow were organized at the intervention NHs. The NHs were also provided with color posters emphasizing hand hygiene and a kit that included hygienic products such as alcoholic-based hand sanitizers. Knowledge surveys were performed periodically and served as reminders. MEASUREMENTS The primary end point was the total infection rate (urinary, respiratory, and gastrointestinal infections) in those infection cases classified either as definite or probable. Analyses corresponded to the underlying design and were performed according to the intention-to-treat principle. This study was registered (#NCT01069497). RESULTS Forty-seven NHs (4515 residents) were included and followed. The incidence rate of the first episode of infection was 2.11 per 1000 resident-days in the interventional group and 2.15 per 1000 resident-days in the control group; however, the difference between the groups did not reach statistical significance in either the unadjusted (Hazard Ratio [HR] = 1.00 [95% confidence interval (CI) 0.89-1.13]; P = .93]) or the adjusted (HR = 0.99 [95% CI 0.87-1.12]; P = .86]) analysis. CONCLUSION Disentangling the impact of this type of intervention involving behavioral change in routine practice in caregivers from the prevailing environmental and contextual determinants is often complicated and confusing to interpret the results.

Abstract
INTRODUCTION The common occurrence of infectious diseases in nursing homes and residential care facilities may result in substantial antibiotic use, and consequently antibiotic resistance. Focusing on these settings, this article aims to provide a comprehensive overview of the literature available on antibiotic use, antibiotic resistance, and strategies to reduce antibiotic resistance. METHODS Relevant literature was identified by conducting a systematic search in the MEDLINE and EMBASE databases. Additional articles were identified by reviewing the reference lists of included articles, by searching Google Scholar, and by searching Web sites of relevant organizations. RESULTS A total of 156 articles were included in the review. Antibiotic use in long term care facilities is common; reported annual prevalence rates range from 47% to 79%. Part of the prescribed antibiotics is potentially inappropriate. The occurrence of antibiotic resistance is substantial in the long term care setting. Risk factors for the acquisition of resistant pathogens include prior antibiotic use, the presence of invasive devices, such as urinary catheters and feeding tubes, lower functional status, and a variety of other resident- and facility-related factors. Infection with antibiotic-resistant pathogens is associated with increased morbidity, mortality, and health care costs. Two general strategies to reduce antibiotic resistance in long term care facilities are the implementation of infection control measures and antibiotic stewardship. CONCLUSION The findings of this review call for the conduction of research and the development of policies directed at reducing antibiotic resistance and its subsequent burden for long term care facilities and their residents.

Abstract
The purpose of this study was to determine the impact of identifying and treating infections on functional outcomes and length of stay (LOS). Our retrospective naturalistic study reviewed all new admissions to a tertiary geriatric psychiatry teaching hospital from 2003 to 2007. Over this four-year period, 390 patients were admitted and discharged with 21% (85) of patients identified as having infections on admission. Those with infections were compared to the group without to determine and compare clinical characteristics. Factors included in analysis were: age, gender, diagnoses, medical comorbidity, neuropsychiatric symptoms, functional outcomes, medications and LOS. Both groups were similar in gender, psychiatric diagnoses and severity of dementia. Those requiring antibiotics for treatment of infections on admission, were older (p=0.003), had poorer baseline function (p=0.005) and higher medical comorbidity (p<0.001). At discharge, the group with infections showed greater functional improvement (p<0.001), particularly in mobility (p=0.005) and cognition (p=0.046), and had a shorter LOS (p=0.02). We conclude that a significant number of patients in tertiary geriatric services continue to have infections on admission. Early identification and treatment of infections can result in improved function and decreased LOS.

Abstract
BACKGROUND many elderly suffer from urinary incontinence and use absorbent pads. Pad use per day (PPD) is a frequently used measure of urinary incontinence. Nursing home residents are often dependent on help from nursing staff to change pads. This study was performed in order to determine whether PPD is a reliable method to quantify urinary incontinence in nursing home residents. Furthermore, the association between urinary tract infections (UTIs), PPD and fluid intake was studied. METHODS data were retrieved from a multicentre, prospective surveillance among nursing home residents. Data on the use of absorbent pads, fluid intake and incontinence volumes were collected during 48 h. During a 1-year follow-up period, data on UTIs were collected. RESULTS in this study, 153 residents were included, of whom 118 (77%) used absorbent pads. Residents who used absorbent pads were at increased risk of developing UTIs compared to residents who did not use pads (41 vs 11%; P = 0.001). Daily fluid intake was not associated with UTIs (P = 0.46). The number of pad changes showed no correlation with the risk of developing UTIs (P = 0.62). Patients with a given PPD presented a wide range of incontinence volumes. CONCLUSION the use of absorbent pads is associated with an increased risk of developing UTIs. PPD and daily fluid intake are not correlated with the risk of developing UTIs. PPD is an unreliable measure of urinary incontinence in nursing home residents.

Abstract
The objective was to examine the effect of BMI on the incidence of various infectious diseases in institutionalised, geriatric subjects. In a retrospective cohort study we analysed medical records of 619 patients aged 75 years and older (mean age 87.6 (sd 6.4) years) who were treated in a geriatric hospital in Vienna, Austria. The total incidence rate of infection in this population was 0.80 per person-year. The most frequent infections were urinary tract infections (0.30 per person-year), followed by infections of the lower respiratory tract (0.19 per person-year), diarrhoea (0.12 per person-year) and other infections (0.20 per person-year). Incidence risk ratios were obtained by a multiplicative Poisson regression model. There was a J-shaped curve in the incidence of infections recorded by BMI with a nadir at 27-28 kg/m2. Compared with the reference group with a BMI of 24-27.9 kg/m2, subjects with a lower BMI had a higher incidence rate of infections. The incidence risk ratios, adjusted for sex, age and chronic diseases, were 1.62 (95 % CI 1.21, 2.17) for those with a BMI of < 20 kg/m2 and 1.84 (95 % CI 1.40, 2.42) for those with a BMI of 20-23.9 kg/m2. However, also patients with a BMI of 28 kg/m2 and above had a higher incidence rate of infections, with an incidence risk ratio of 1.54 (95 % CI 1.07, 2.22). These results show that both underweight and obesity are associated with a higher risk of infections in institutionalised geriatric patients.

Abstract
Bacteremia is an increasingly significant health problem among the elderly. Older adults may present with atypical manifestations of bacteremia. In addition, there are age-related differences in etiologic agents and corresponding resistance patterns. Important factors to consider when prescribing antibiotics for older adults with bacteremia include the severity and source of infection, antimicrobial susceptibility of the organism and renal function. The association between increasing age and poor outcomes in patients with bacteremia is well established. Despite the current paucity of data, the understanding of the natural history of bacteremia in the elderly should not be limited to mortality but should also focus on functional status, cognitive function and the eventual need for long-term care. Appropriate management of bacteremia in the elderly requires timely administration of broad-spectrum antibiotics in addition to managing key geriatric issues. Further studies are required to assess the impact of using broader outcomes other than mortality when addressing bacteremia in the elderly.

Abstract
This planning study was designed and conducted in a predominantly rural Canadian province to examine the strengths and learning needs of four categories of nursing staff practising in New Brunswick nursing homes. Participants included directors of care, registered nurses, licensed practical nurses, and resident attendants. The nursing homes ranged in size from 38 to 196 beds and were located throughout the province. In health and planning studies, ethnography conveys a coherent statement of peoples' local knowledge as culture-sharing groups (Muecke, 1994). The study derived information from the Nursing Home Act, reports, the literature, key informants, and direct observations of and interviews with participants. Leadership strengths defined the roles for categories of staff and supported the capacity of each category to identify their learning needs. In conclusion, nurses practising in nursing homes can and must take an active role in decision making for their learning.

Abstract
Prominent among the numerous events that contribute to the enhanced susceptibility of elderly patients to infection is the decline of immune function that accompanies aging. Elderly patients experience a marked decline in cell-mediated immune function and reduced humoral immune function. Age-dependent defects in T and B cell function are readily demonstrable in elderly patients, yet the essential elements of innate immunity are remarkably well preserved. The cytokine and chemokine signaling networks are altered in elderly patients and tends to favor a type 2 cytokine response over type 1 cytokine responses. The induction of proinflammatory cytokines after septic stimuli is not adequately controlled by anti-inflammatory mechanisms in elderly persons. This immune dysregulation is accompanied by a more pronounced procoagulant state in older patients. These molecular events function in concert to render elderly patients at excess risk for mortality from severe sepsis and septic shock.

Abstract
The impact of the combination therapy fludarabine plus cyclophosphamide (FC) in comparison with fludarabine alone regarding the incidence and severity of infections among previously untreated patients with chronic lymphocytic leukaemia (CLL) was evaluated within a multicentre phase III study. A total of 375 patients, up to 65 years old, were randomised between fludarabine or FC for first line therapy. No routine anti-infective prophylaxis was provided. A total of 196 infectious episodes, including 33 severe infections, were documented. In the fludarabine arm, 32.9% of the patients developed an infectious complication compared with 39.9% in the FC arm (P = 0.2). No difference was observed in the rate of severe infections (Common Toxicity Criteria grades III and IV) between both treatment arms. Dose reductions were performed more frequently in FC-treated patients. Granulocyte colony-stimulating factor (G-CSF) was administered due to leucopenia in 5% of all patients. A multivariate regression model identified only elevated thymidine kinase, but not the treatment arm, as a statistically independent risk factor for infections. In summary, FC was not associated with a higher rate of infections compared with fludarabine alone. No routine antibiotic or virostatic prophylaxis, or preemptive treatment with G-CSF, is necessary in first line therapy with fludarabine-based regimens in younger patients with CLL, if adequate dose reduction is performed. The combination therapy FC is not associated with a higher rate of infections compared with fludarabine alone. No routine antibiotic or virostatic prophylaxis as well as preemptive treatment with G-CSF is necessary in first line therapy with fludarabine-based regimen in younger patients with CLL, if adequate dose reductions due to cytopenia or previous infections are performed.

Abstract
BACKGROUND The prevalence of infections caused by extended-spectrum beta -lactamase (ESBL)-producing Enterobacteriaceae is increasing worldwide. The influx of these bacteria into hospitals has major implications for infection-control and empirical treatment strategies. METHODS Isolates from 2 patient cohorts--patients with gram-negative bacteremia within 2 days after admission and patients screened for fecal colonization at admission--were assessed for ESBL production. ESBL phenotype was confirmed according to Clinical and Laboratory Standards Institute guidelines. Predictors of ESBL phenotype were examined by univariate and multivariate analyses. RESULTS Of 80 Enterobacteriaceae isolates from blood samples obtained at admission to the hospital, 13.7% produced ESBL. Thirty-eight patients with ESBL-positive isolates and 72 with ESBL-negative isolates were included in a case-control study. Predictors of ESBL production were male sex and nursing home residence (area under receiver operator characteristic curve, 0.7). Of 241 persons screened at admission, 26 (10.8%) had fecal carriage of ESBL-producing Enterobacteriaceae. Predictors of fecal carriage were poor functional status, antibiotic use, chronic renal insufficiency, liver disease, and use of histamine2 blockers (area under receiver operator characteristic curve, 0.8). Four (15.4%) of the 26 individuals with fecal carriage had subsequent bacteremia with ceftazidime-resistant Enterobacteriaceae, compared with 1 (0.5%) noncarrier (odds ratio, 38.9; P<.001). Of 80 ESBL-producing Enterobacteriaceae isolates obtained at admission, 65 were health care associated, and 15 were community acquired. The 15 community-acquired ESBL-producing Enterobacteriaceae belonged to diverse clones. The most prevalent ESBL gene among these isolates was CTX-M-2 (found in 53.3% of the isolates). CONCLUSIONS We report high rates of bacteremia and colonization with ESBL-producing Enterobacteriaceae at admission to our institution, which may undermine infection-control measures and complicate the selection of empirical treatment.

Abstract
The objective of the article is to explore the impact quality management systems and quality assurance activities in nursing homes have on clinical outcomes. The results are based on a cross-sectional study in 65 Dutch nursing homes. The management of the nursing homes as well as the residents (N = 12,377) participated in the study. Primary survey-data about the implementation of quality management systems and quality assurance activities were collected in 1994/1995 and in 1998, and were combined with information on resident characteristics and the prevalence of undesirable clinical outcomes. The results demonstrate that there are differences between nursing homes in the prevalence of undesirable clinical outcomes. In the nursing homes with the lowest scores, undesirable outcomes occur approximately 10 times less often than in nursing homes with the highest scores. The multi-level analysis has demonstrated that the differences in outcomes are mainly caused by differences between residents and, to some extent, also by differences between nursing homes. Resident characteristics explain 48% of the differences between residents and 72% of the differences between nursing homes. The size of the nursing home, the involvement of a client council and the implementation of a quality management system could explain a small part of the remaining variation in the number of undesirable outcomes. It seems that the implementation of a quality management system and the involvement of a client council had significant influence on the number of undesirable outcomes. Approximately 50% of the undesirable outcomes cannot be explained by the selected resident characteristics, the size of the nursing home and the implementation of quality management systems or quality assurance activities.
