Abstract
INTRODUCTION Since 2012, the European Centre for Disease Prevention and Control (ECDC) promotes a point prevalence survey (PPS) of HAIs in European acute care hospitals. Through a retrospective analysis of 2012, 2015 and 2017 PPS of HAIs performed in a tertiary academic hospital in Italy, we developed a model to predict the risk of HAI. METHODS Following ECDC protocol we surveyed 1382 patients across three years. Bivariate logistic regression analyses were conducted to assess the relationship between HAI and several variables. Those statistically significant were included in a stepwise multiple regression model. The goodness of fit of the latter model was assessed with the Hosmer-Lemeshow test, ultimately constructing a probability curve to estimate the risk of developing HAIs. RESULTS Three variables resulted statistically significant in the stepwise logistic regression model: length of stay (OR 1.03; 95% CI: 1.02-1.05), devices breaking the skin (i.e. peripheral or central vascular catheter, OR 4.38; 95% CI: 1.52-12.63), urinary catheter (OR 4.71; 95% CI: 2.78-7.98). CONCLUSION PPSs are a convenient and reliable source of data to develop HAIs prediction models. The differences found between our results and previously published studies suggest the need of developing hospital-specific databases and predictive models for HAIs.

Abstract
Nosocomial infections or healthcare-acquired infections are a common cause of increased morbidity and mortality among hospitalized patients. Cancer patients are at an increased risk for these infections due to their immunosuppressed states. Considering these adverse effects on and the socioeconomic burden, efforts should be made to minimize the transmission of these infections and make the hospitals a safer environment. These infection rates can be significantly reduced by the implementing and improving compliance with the “care bundles.” This chapter will address the common nosocomial infections such as ventilator-associated pneumonia (VAP), catheter-associated urinary tract infections (CAUTI), and surgical site infections (SSI), including preventive strategies and care bundles for the same.

Abstract
Health care-associated infections (HCAIs) are infections that occur while receiving health care, developed in a hospital or other health care facility that first appear 48 hours or more after hospital admission, or within 30 days after having received health care. Multiple studies indicate that the common types of adverse events affecting hospitalized patients are adverse drug events, HCAIs, and surgical complications. The US Center for Disease Control and Prevention identifies that nearly 1.7 million hospitalized patients annually acquire HCAIs while being treated for other health issues and that more than 98,000 patients (one in 17) die due to these. Several studies suggest that simple infection-control procedures such as cleaning hands with an alcohol-based hand rub can help prevent HCAIs and save lives, reduce morbidity, and minimize health care costs. Routine educational interventions for health care professionals can help change their hand-washing practices to prevent the spread of infection. In support of this, the WHO has produced guidelines to promote hand-washing practices among member countries.

Abstract
PURPOSE Trauma-related injuries are the leading cause of death worldwide. Some risk factors make traumatic patients susceptible to infection. Furthermore, some mortality risk factors, including length of hospitalization and increasing age, were detected in non-traumatic infected patients. This study aimed to assess mortality risk factors among nosocomial infected traumatic patients in Rajaee trauma center, Shiraz, Iran. METHODS This prospective cohort study was conducted during a period of 2 years since April 2015 to March 2017 in Rajaee hospital, which is the center of emergency medical services for traumatic injuries in Shiraz, Iran. Centers for Disease Control and Prevention/National Healthcare Safety Network surveillance system criteria were applied to define 5 types of nosocomial infections. The variables analyzed as the risk factors of infection and mortality included sex, age, mechanism of injury, site of injury, injury severity score (ISS), surgical intervention, length of hospitalization, intensive care unit (ICU) admission, and type of pathogen. Then, the incidence of nosocomial infection and also risk factors of mortality in traumatic patients were evaluated. All data analyses were performed using the statistical package for social sciences, version 15 (SPSS Inc., Chicago) and p ≤ 0.05 is considered to be statistically significant. RESULTS The incidence of nosocomial infection was 7.2% (p < 0.001). Pneumonia was the most common type of infection detected in our study. Infection led to a 7.8-fold increase in mortality of the traumatic patients (p < 0.001). Admission in intensive care units and old age were the main risk factors of mortality in infected traumatic patients. Old age, gunshot and motor vehicle accidents, trauma to extremities and abdomen, higher injury severity score, and prolonged hospitalization, made the traumatic patients more susceptible to infection. CONCLUSION The really high incidence of nosocomial infection in traumatic patients in Iran depends on some risk factors that should be considered. Also infection increases the mortality rate in the traumatic patients, which could be reduced by eliminating its risk factors.

Abstract
Background & objectives: Hospital-acquired infections (HAIs) are a major challenge to patient safety and have serious public health implications by changing the quality of life of patients and sometimes causing disability or even death. The true burden of HAI remains unknown, particularly in developing countries. The objective of this study was to estimate point prevalence of HAI and study the associated risk factors in a tertiary care hospital in Pune, India. Methods: A series of four cross-sectional point prevalence surveys were carried out between March and August 2014. Data of each patient admitted were collected using a structured data entry form. Centers for Disease Control and Prevention guidelines were used to identify and diagnose patients with HAI. Results: Overall prevalence of HAI was 3.76 per cent. Surgical Intensive Care Unit (ICU) (25%), medical ICU (20%), burns ward (20%) and paediatric ward (12.17%) were identified to have significant association with HAI. Prolonged hospital stay [odds ratio (OR=2.81), mechanical ventilation (OR=18.57), use of urinary catheter (OR=7.89) and exposure to central air-conditioning (OR=8.59) had higher odds of acquiring HAI (P<0.05). Interpretation & conclusions: HAI prevalence showed a progressive reduction over successive rounds of survey. Conscious effort needs to be taken by all concerned to reduce the duration of hospital stay. Use of medical devices should be minimized and used judiciously. Healthcare infection control should be a priority of every healthcare provider. Such surveys should be done in different healthcare settings to plan a response to reducing HAI.

Abstract
BACKGROUND Healthcare-associated infection (HCAI) represents a major problem for patient safety worldwide. AIM To demonstrate the prevalence, causative agents, and risk factors for HCAI in Chinese hospitals. METHODS A one-day point-prevalence survey was conducted in 52 Chinese hospitals between October 2014 and March 2015. A web-based software system was developed for data entry and management. FINDINGS Among 53,939 patients surveyed, the prevalence of patients with at least one HCAI was 3.7%. Of 2182 HCAI episodes, the most frequently occurring types were lower respiratory tract infections (47.2%), followed by urinary tract infection (12.3%), upper respiratory tract infection (11.0%), and surgical site infection (6.2%). The prevalence of patients with at least one HCAI in critical care units was highest (17.1%). Device-associated infections, including ventilator-associated pneumonia, catheter-associated urinary tract infection, and central catheter-associated bloodstream infection, accounted for only 7.9% of all HCAIs. The most frequently isolated micro-organisms were Pseudomonas aeruginosa [206 infections (9.4%)], Acinetobacter baumannii [172 infections (7.9%)], Klebsiella pneumoniae [160 infections (7.3%)], and Escherichia coli [145 infections (6.6%)]. Of the survey patients (18,206/53,939), 33.8% were receiving at least one antimicrobial agent at the time of the survey. Risk factors for HCAI included older age (≥80 years), male gender, days of hospital admission, admission into a critical care unit, and device utilization. CONCLUSION Our study suggests that the overall prevalence of HCAI in surveyed Chinese hospitals was lower than that reported from most European countries and the USA. More attention should be given to the surveillance and prevention of non-device-associated HCAI in China.

Abstract
Introduction The second Slovenian national healthcare-associated infections (HAIs) prevalence survey (SNHPS) was conducted in acute-care hospitals in 2011. The objective was to assess the sensitivity and specificity of the method used for the ascertainment of six types of HAIs (bloodstream infections, catheter-associated infections, lower respiratory tract infections, pneumoniae, surgical site infections, and urinary tract infections) in the University Medical Centre Ljubljana (UMCL). Methods A cross-sectional study was conducted in patients surveyed in the SNHPS in the UMCL using a retrospective medical chart review (RMCR) and European HAIs surveillance definitions. Sensitivity and specificity of the method used in the SNHPS using RMCR as a reference was computed for ascertainment of patients with any of the six selected types of HAIs and for individual types of HAIs. Agreement between the SNHPS and RMCR results was analyzed using Cohen’s kappa coefficient. Results 1474 of 1742 (84.6%) patients surveyed in the SNHPS were included in RMCR. The sensitivity of the SNHPS method for detecting any of six HAIs was 90% (95% confidence interval (CI): 81%-95%) and specificity 99% (95% CI: 98%-99%). The sensitivity by type of HAI ranged from 63% (lower respiratory tract infections) to 92% (bloodstream infections). Specificity was at least 99% for all types of HAIs. Agreement between the two data collection approaches for HAIs overall was very good (κ=0.83). Conclusions The overall sensitivity of SNHPS collection method for ascertaining HAIs overall was high and the specificity was very high. This suggests that the estimated prevalence of HAIs in the SNHPS was credible.

Abstract
Introduction In the second Slovenian national healthcare-associated infections (HAIs) prevalence survey, conducted within the European point prevalence survey of HAIs and antimicrobial use in acute-care hospitals, we estimated the prevalence of all types of HAIs and identified risk factors. Methods Patients from acute-care hospitals were enrolled into a one-day cross-sectional study in October 2011. Descriptive analyses were performed to describe the characteristics of patients, their exposure to invasive procedures and the prevalence of different types of HAIs. Univariate and multivariate analyses of association of having at least one HAI with possible risk factors were performed to identify risk factors. Results Among 5628 patients, 3.8% had at least one HAI and additional 2.6% were still being treated for HAIs on the day of the survey; the prevalence of HAIs was 6.4%. The prevalence of urinary tract infections was the highest (1.4%), followed by pneumoniae (1.3%) and surgical site infections (1.2%). In intensive care units (ICUs), the prevalence of patients with at least one HAI was 35.7%. Risk factors for HAIs included central vascular catheter (adjusted odds ratio (aOR) 4.0; 95% confidence intervals (CI): 2.9-5.7), peripheral vascular catheter (aOR 2.0; 95% CI: 1.5-2.6), intubation (aOR 2.3; 95% CI: 1.4-3.5) and rapidly fatal underlying condition (aOR 2.1; 95% CI: 1.4-3.3). Conclusions The prevalence of HAIs in Slovenian acute-care hospitals in 2011 was substantial, especially in ICUs. HAIs prevention and control is an important public health priority. National surveillance of HAIs in ICUs should be developed to support evidence-based prevention and control.

Abstract
Objective.To explore differences in the prevalence of healthcare-associated infections (HAIs) according to survey methodology.Design.Repeated point and period prevalence survey strategies.Setting.University-affiliated primary and tertiary care center.Methods.Analysis of data collected from 2006 to 2012 from annual HAI prevalence surveys using definitions proposed by the US Centers for Disease Control and Prevention. The study design allowed the analysis of the same data in the format of a point or a period prevalence survey.Results.Pooled point and period HAI prevalence was 7.46% and 9.84% (+32%), respectively. This additional 32% was mainly attributable to infections of the lower respiratory tract (2.42% vs 3.20% [+32%]) and the urinary tract (1.76% vs 2.62% [+49%]). Differences in surgical site infections (1.02% vs 1.20% [+19%]) and bloodstream infections (0.76% vs 0.86% [+13%]) were smaller. HAI prevalence for the point and period methodology in acute and long-term care were 7.47% versus 9.38 (+26%) and 8.37% versus 11.89% (+42%), respectively. Differences were stable over time. Focusing on the 4 major HAIs (respiratory tract, urinary tract, surgical site, and bloodstream infections) misses one-quarter of all HAIs.Conclusions.More HAIs are identified by the period prevalence method, especially those of shorter duration (lower respiratory and urinary tract), which would make this method more suitable to be used in long-term care. Results of the 2 study methods cannot be benchmarked against each other.Infect Control Hosp Epidemiol2014;35(6):674–684

Abstract
Background This study aimed to investigate the prevalence of healthcare-associated infection (HAI) in the China-Japan Friendship Hospital, a tertiary level hospital in Beijing, China. Methods We defined HAI using the criteria established by the Ministry of Health of the People’s Republic of China. Three cross-sectional surveys were conducted from 2012 to 2014. Inpatients who had been hospitalized for at least 48 h were surveyed. Information on HAI prevalence, isolated pathogens and use of antibiotics were collected. Logistic regression models were used to assess the associations between HAI and potential risk factors. Results During three cross-sectional surveys, a total number of 4,029 patients were included (1,233 patients in 2012, 1,220 patients in 2013 and 1,576 patients in 2014). The overall prevalence of patients with HAI was 3.6 % (95 % confidence interval (CI) 3.1 %–4.2 %). Respiratory tract infections were the most common type (64.7 %) of HAIs, followed by urinary tract infections (12.6 %) and bloodstream infections (5.4 %). HAI occurrences were significantly associated with male sex (odds ratio (OR) = 2.25, 95 % CI 1.53-3.32), age over 85 years (OR = 4.74, 95 % CI 2.54–8.83), hospitalization in the intensive care units (ICUs) (OR = 2.42, 95 % CI 1.31–4.49), indwelling urinary catheter (OR = 4.21, 95 % CI 2.46–7.20) and mechanical ventilation (OR = 2.31, 95 % CI 1.30–4.09). Gram-negative bacteria were found to be the most isolated pathogens (67.1 %), with gram-positive bacteria and fungi accounted for 20.3 % and 10.5 %, respectively. Antibiotics were administered to 34.3 % of the included patients over the study period. Conclusions The overall HAI prevalence in our hospital is similar to previous studies that were conducted in other areas of China, and the respiratory tract infection should be the priority in HAI reduction control within China. We should focus HAI reduction efforts on patients with advanced age, hospitalization in the ICU and indwelling devices.

[PMID: 26277574 DOI: 10.1016/j.ajic.2015.07.006] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2015] [Revised: 06/27/2015] [Accepted: 07/02/2015] [Indexed: 01/24/2023]
Abstract
BACKGROUND Health care-acquired infections (HAIs) constitute an increasing threat for patients worldwide. Potential contributors of HAIs include environmental surfaces in health care settings, where ultraviolet-C radiation (UV-C) is commonly used for disinfection. This UV-C intervention-based pilot study was conducted in a hospital setting to identify any change in the incidence of HAIs before and after UV-C intervention, and to determine the effectiveness of UV-C in reducing pathogens. METHODS In a hospital in Culver City, CA, during 2012-2013, bactericidal doses of UV-C radiation (254 nm) were delivered through a UV-C-based mobile environmental decontamination unit. The UV-C dosing technology and expertise of the specifically trained personnel were provided together as a dedicated service model by a contracted company. The incidence of HAIs before and after the intervention period were determined and compared. RESULTS The dedicated service model dramatically reduced HAIs (incidence difference, 1.3/1000 patient-days, a 34.2% reduction). Reductions in the total number and incidence proportions (28.8%) of HAIs were observed after increasing and maintaining the coverage of UV-C treatments. CONCLUSION The dedicated service model was found to be effective in decreasing the incidence of HAIs, which could reduce disease morbidity and mortality in hospitalized patients. This model provides a continuously monitored and frequently UV-C-treated patient environment. This approach to UV-C disinfection was associated with a decreased incidence of HAIs.

Abstract
INTRODUCTION Our study was conducted, in university hospital center (UHC) Farhat Hached of Sousse (city in Tunisian center-east), within healthcare-associated infections (HAI) epidemiological surveillance (ES) program, based, among others, on HAI regular prevalence surveys. Our objectives are to resituate HAI prevalence rate and to identify their risk factors (RF) in order to adjust, in our hospital, prevention programs. METHODS It is a transversal descriptive study, including all patients who had been hospitalized for at least 48 hours, measuring prevalence of HAI a "given day", with only one passage by service. Risk factors were determined using Epiinfo 6.0, by uni-varied analysis, then, logistic regression stepwise descending for the variables whose p. RESULTS The study focused on 312 patients. Infected patients prevalence was 12.5% and that of HAI was 14.5%. Infections on peripheral venous catheter (PVC) dominated (42.2%) among all HAI identified. HAI significant RF were neutropenia (p < 10(-4)) for intrinsic factors, and PVC for extrinsic factors (p = 0,003). CONCLUSION Predominance of infections on PVC should be subject of specific prevention actions, including retro-information strategy, prospective ES, professional practices evaluation and finally training and increasing awareness of health personnel with hygiene measures. Finally, development of a patient safety culture with personnel ensures best adherence to hygiene measures and HAI prevention.

Abstract
Objective.To monitor hospital-wide trends in the prevalence of hospital-acquired infections (HAIs) in order to identify areas where the risk of infection is increasing.Methods.Successive surveillance surveys were conducted twice yearly, from November 2001 until May 2004, to determine the prevalence of HAIs at 2 Dutch hospitals, using Centers for Disease Control and Prevention criteria.Results.In all, 340 HAIs were observed in 295 (11.1%) of 2,661 patients surveyed. The overall prevalence per survey varied from 10.2% to 15.6%, with no significant differences between successive surveys. In the surgical department, the prevalence of HAIs increased from 10.8 cases per 100 surgeries in November 2001 to 20.4 cases per 100 surgeries in May 2002. Further analysis revealed a high prevalence of surgical site infection among patients who had an orthopedic procedure performed. In the neurology-neurosurgery department, the prevalence increased from 13.0 cases per 100 patients in May 2002 to 26.6 cases per 100 patients in May 2003 and involved several types of infection. Further analysis retrieved exceptionally high incidences of infections associated with cerebrospinal fluid drainage. Specific infection control interventions were developed and implemented in both departments. The total cost of the surveys was estimated to be €9,100 per year.Conclusion.Successive performance of surveillance surveys is a simple and cheap method to monitor the prevalence of infection throughout the hospital and appeared instrumental in identifying 2 departments with increased infection rates.

Abstract
Objective.To examine the effect of heterogeneous case mix for a benchmarking analysis and interhospital comparison of the prevalence rates of nosocomial infection.Design.Cross-sectional survey.Setting.Eleven hospitals located in Cyprus and in the region of Crete in Greece.Methods.The survey included all inpatients in the medical, surgical, pediatric, and gynecology-obstetrics wards, as well as those in intensive care units. Centers for Disease Control and Prevention criteria were used to define nosocomial infection. The information collected for all patients included demographic characteristics, primary admission diagnosis, Karnofsky functional status index, Charlson comorbidity index, McCabe- Jackson severity of illness classification, use of antibiotics, and prior exposures to medical and surgical risk factors. Outcome data were also recorded for all patients. Case mix-adjusted rates were calculated by using a multivariate logistic regression model for nosocomial infection risk and an indirect standardization method.Results.The overall prevalence rate of nosocomial infection was 7.0% (95% confidence interval, 5.9%–8.3%) among 1,832 screened patients. Significant variation in nosocomial infection rates was observed across hospitals (range, 2.2%–9.6%). Logistic regression analysis indicated that the mean predicted risk of nosocomial infection across hospitals ranged from 3.7% to 10.3%, suggesting considerable variation in patient risk. Case mix-adjusted rates ranged from 2.6% to 12.4%, and the relative ranking of hospitals was affected by case-mix adjustment in 8 cases (72.8%). Nosocomial infection was significantly and independently associated with mortality (adjusted odds ratio, 3.6 [95% confidence interval, 2.1–6.1]).Conclusion.The first attempt to rank the risk of nosocomial infection in these regions demonstrated the importance of accounting for heterogeneous case mix before attempting interhospital comparisons.

Abstract
BACKGROUND Currently, no single U.S. surveillance system can provide estimates of the burden of all types of health care-associated infections across acute care patient populations. We conducted a prevalence survey in 10 geographically diverse states to determine the prevalence of health care-associated infections in acute care hospitals and generate updated estimates of the national burden of such infections. METHODS We defined health care-associated infections with the use of National Healthcare Safety Network criteria. One-day surveys of randomly selected inpatients were performed in participating hospitals. Hospital personnel collected demographic and limited clinical data. Trained data collectors reviewed medical records retrospectively to identify health care-associated infections active at the time of the survey. Survey data and 2010 Nationwide Inpatient Sample data, stratified according to patient age and length of hospital stay, were used to estimate the total numbers of health care-associated infections and of inpatients with such infections in U.S. acute care hospitals in 2011. RESULTS Surveys were conducted in 183 hospitals. Of 11,282 patients, 452 had 1 or more health care-associated infections (4.0%; 95% confidence interval, 3.7 to 4.4). Of 504 such infections, the most common types were pneumonia (21.8%), surgical-site infections (21.8%), and gastrointestinal infections (17.1%). Clostridium difficile was the most commonly reported pathogen (causing 12.1% of health care-associated infections). Device-associated infections (i.e., central-catheter-associated bloodstream infection, catheter-associated urinary tract infection, and ventilator-associated pneumonia), which have traditionally been the focus of programs to prevent health care-associated infections, accounted for 25.6% of such infections. We estimated that there were 648,000 patients with 721,800 health care-associated infections in U.S. acute care hospitals in 2011. CONCLUSIONS Results of this multistate prevalence survey of health care-associated infections indicate that public health surveillance and prevention activities should continue to address C. difficile infections. As device- and procedure-associated infections decrease, consideration should be given to expanding surveillance and prevention activities to include other health care-associated infections.

Abstract
BACKGROUND Nosocomial infections (NI) increase morbidity and mortality. Studies of their prevalence in single institutions can reveal trends over time and help to identify risk factors. METHODS In March and April 2010, data were prospectively recorded from all inpatients at the Hannover Medical School (Germany) except those treated in the pediatric, psychosomatic, and psychiatric services. The data were acquired systematically by chart review and by interviews with the medical staff. Infections were classified according to the definitions of the Centers for Disease Control and Prevention (CDC). Information was obtained on underlying diseases, invasive procedures, the use of antibiotics, devices (the application of specific medical techniques such as drainage, vascular catheters, etc.), and detected pathogens. RESULTS Of the 1047 patients studied, 117 (11.2%) had a total of 124 nosocomial infections, while 112 (10.7%) had 122 community-acquired infections. The most common NI were surgical site infections (29%), infections of the gastrointestinal tract (26%) and respiratory tract (19%), urinary tract infections (16%), and primary sepsis (4%). The most common pathogens were Escherichia coli, coagulase-negative staphylococci, Candida spp., Enterococcus spp., and Pseudomonas aeruginosa. Multivariable regression analysis revealed the following independent risk factors for NI: antibiotic treatment in the last 6 months (odds ratio [OR] = 2.9), underlying gastrointestinal diseases (OR = 2.3), surgery in the last 12 months (OR = 1.8), and more than two underlying diseases (OR = 1.7). Each additional device that was used gave rise to an OR of 1.4. Further risk factors included age, length of current or previous hospital stay, trauma, stay on an intensive care unit, and artificial ventilation. CONCLUSION In this prevalence study, NI were a common complication. Surgical site infections were the single most common type of NI because of the large number of patients that underwent surgical procedures in our institution. More investigation will be needed to assess the benefit of prevalence studies for optimizing appropriate, effective preventive measures.

Abstract
Background Exposure to urinary catheters is considered the most important risk factor for healthcare-associated urinary tract infection (UTI) and is associated with significant morbidity and substantial extra-costs. In this study, we assessed the impact of urinary catheterisation (UC) on symptomatic healthcare-associated UTI among hospitalized patients. Methods A nationwide period prevalence survey of healthcare-associated infections was conducted during 1 May to 30 June 2004 in 49 Swiss hospitals and included 8169 adult patients (4313 female; 52.8%) hospitalised in medical, surgical, intermediate, and intensive care wards. Additional data were collected on exposure to UC to investigate factors associated with UTI among hospitalised adult patients exposed and non-exposed to UC. Results 1917 (23.5%) patients were exposed to UC within the week prior to survey day; 126 (126/8169; 1.5%) developed UTI. Exposure to UC preceded UTI only in 73 cases (58%). By multivariate logistic regression analysis, UTI was independently associated with exposure to UC (odds ratio [OR], 3.9 [95% CI, 2.6-5.9]), female gender (OR, 2.1 [95% CI, 1.4-3.1]), an American Society of Anesthesiologists’ score > 2 points (OR, 3.2 [95% CI, 1.1-9.4], and prolonged hospital stay >20 days (OR, 1.9 [95% CI, 1.4-3.2]. Further analysis showed that the only significant factor for UTI with exposure to UC use was prolonged hospital stay >40 days (OR, 2.9 [95% CI, 1.3-6.1], while female gender only showed a tendency (OR, 1.6 [95% CI, 1.0-2.7]. In the absence of exposure to UC, the only significant risk factor for UTI was female gender (OR, 3.3 [95% CI, 1.7-6.5]). Conclusions Exposure to UC was the most important risk factor for symptomatic healthcare-associated UTI, but only concerned about half of all patients with UTI. Further investigation is warranted to improve overall infection control strategies for UTI.

Abstract
In developing countries, few data are available on healthcare-associated infections. In Burkina Faso, there has been a failure to take into account risk management and patient safety in the quality assurance program. The main objective of our study was to carry out an assessment of healthcare-associated infection in a first level hospital. We conducted a cross-sectional study in June 2011 in the care units of Ziniaré District Hospital (Ziniaré, Burkina Faso). The hospital has been divided in three components: i) hospital population (care providers, in-patients and patients' guardians); ii) healthcare and services organization; iii) hospital environment. We included: care providers of the clinical services, hospital in-patients and patients' guardians, hospitalization infrastructure and nursing units, and all the documents relating to standards and protocols. Data collection has been done by direct observation, interviews and biological samples taken at different settings. In hospital population, care providers and patients' guardians represented a high source of infection: adherence to hygiene practice on the part of care providers was low (12/19), and no patients' guardian experienced good conditions of staying in the hospital. In healthcare and services organization, healthcare waste management represented a high-risk source of infection. In hospital environment, hygiene level of the infrastructure in the hospital rooms was low (6.67%). Prevalence of isolated bacteria was 71.8%. Urinary-tract catheters infections were the most significant in our sample, followed by surgical-site infections. In total, 56.26% (9/19) of germs were -Lactamase producers (ESBL). They were represented by Escherichia coli and Klebsiella pneumoniae. Our analysis identified clearly healthcare-associated infection as a problem in Ziniaré district hospital. Hence, a national program of quality assurance in the hospitals should now integrate the risk infectious management of healthcare-associated infections.

Abstract
UNLABELLED BACKGROUND The aims of this study were to determine the hospital-acquired infections (HAI) prevalence in all institutions of Rabat University Medical Center, to ascertain risk factors, to describe the pathogens associated with HAI and their susceptibility profile to antibiotics. MATERIALS AND METHODS Point-prevalence survey in January 2010 concerning all patients who had been in the hospital for at least 48 hours. At bedside, 27 investigators filled a standardized questionnaire from medical records, temperature charts, radiographs, laboratory reports and by consultation with the ward's collaborating health professionals. Risk factors were determined using logistic regression. RESULTS 1195 patients involved, occupancy rate was 51%. The prevalence of HAI was 10.3%. Intensive care units were the most affected wards (34.5%). Urinary tract infection was the most common infected site (35%). Microbiological documentation was available in 61% of HAI. Staphylococcus was the organism most commonly isolated (18.7%) and was methicillin-resistant in 50% of cases. In multivariate analysis, risk factors associated with HAI were advanced age, longer length of hospital stay, presence of comorbidity, invasive devices and use of antibiotic use. CONCLUSION HAI prevalence was high in this study. Future prevention program should focus on patients with longer length of stay, invasive devices, and overprescribing antibiotics.

Abstract
The first objective of the Catalonian Nosocomial Infection Surveillance Program (VINCat) is to monitor the prevalence (%) of patients with nosocomial infections (NI), patients undergoing urinary catheterization with closed circuit drainage (%) and patients undergoing antibiotic treatment (%). We present the results for the period 2008-2010. Comprehensive and point annual prevalence surveys were conducted that included conventionally hospitalized patients in acute care hospitals belonging to the VINCat Program. The number of participating hospitals was 46 (2008), 48 (2009) and 61 (2010), most belonging to the Network of Public Use Hospitals of Servei Català de la Salut. The results are presented globally and by hospital size (<200 beds, 200-500 beds, >500 beds). The prevalence of patients with active NI acquired during the current or the previous hospitalization (global NI/P%) was 7.6 (2008), 6.2 (2009) and 6.3 (2010). The prevalence of patients with active NI acquired during the current (actual NI/P%) was 6.2 (2008), 4.7 (2009) and 4.6 (2010).The results by hospital size shows that the variation occurred mainly in <200 beds hospitals. The proportion of closed circuit urinary catheterization use was 90.2%. The use of antibiotics varied between 34.6% and 37.6%, with no differences due to hospital size. The global prevalence of NI provides information on the burden of NI at the institutional and regional level. Between 17.3% and 26.9% of patients with NI at the time of the study had acquired it in a previous hospitalization at the same institution.

BACKGROUND Many strategies have been designed and evaluated to address the problem of low hand hygiene (HH) compliance. Which of these strategies are most effective and how they work is still unclear. Here we describe frequently used improvement strategies and related determinants of behaviour change that prompt good HH behaviour to provide a better overview of the choice and content of such strategies. METHODS Systematic searches of experimental and quasi-experimental research on HH improvement strategies were conducted in Medline, Embase, CINAHL, and Cochrane databases from January 2000 to November 2009. First, we extracted the study characteristics using the EPOC Data Collection Checklist, including study objectives, setting, study design, target population, outcome measures, description of the intervention, analysis, and results. Second, we used the Taxonomy of Behavioural Change Techniques to identify targeted determinants. RESULTS We reviewed 41 studies. The most frequently addressed determinants were knowledge, awareness, action control, and facilitation of behaviour. Fewer studies addressed social influence, attitude, self-efficacy, and intention. Thirteen studies used a controlled design to measure the effects of HH improvement strategies on HH behaviour. The effectiveness of the strategies varied substantially, but most controlled studies showed positive results. The median effect size of these strategies increased from 17.6 (relative difference) addressing one determinant to 49.5 for the studies that addressed five determinants. CONCLUSIONS By focussing on determinants of behaviour change, we found hidden and valuable components in HH improvement strategies. Addressing only determinants such as knowledge, awareness, action control, and facilitation is not enough to change HH behaviour. Addressing combinations of different determinants showed better results. This indicates that we should be more creative in the application of alternative improvement activities addressing determinants such as social influence, attitude, self-efficacy, or intention.

Abstract
Background: Hitherto efforts to implement data driven prevention guidelines for hospital-acquired infections (HAI) in Nigeria have been limited by the inadequate knowledge of the risks of these infections. This study evaluated the occurrence of HAI in a foremost tertiary health facility over a 5-year period for the purpose of reinforcing control efforts. Materials and Methods: A retrospective survey of records from the infection control unit of the University College Hospital, Ibadan, Nigeria, was done for the years 2005-09. For the 5 years studied 22,941 in-patients were reviewed and the data of those who developed infections during admission were retrieved and analyzed. The prevalence, types, and causative organisms of HAI were determined. The chi-square test was used to evaluate associations. Results: The prevalence of HAI over the 5-year period was 2.6% (95% CI: 2.4–2.8). Surgical and medical wards had the most infections (48.3%) and (20.5%) respectively. Urinary tract infection (UTI) and surgical site infection (30.7%) were the most prevalent (43.9%) HAI. UTIs were significantly higher in surgical and medical wards, surgical site infections in obstetrics and gynecology wards, and soft tissue infections and bacteremia in pediatric wards (P<0.05). Gram-negative infections occurred about four times as often as gram-positive infections with Klebsiella sp. and staphylococcus aureus being the predominant isolates (34.3%) and (20.1%) respectively. Conclusion: Efforts to limit HAI should be guided by local surveillance data if progress is to be made in improving the quality of patient care in Nigeria.

Abstract
OBJECTIVE To determine healthcare-associated infection (HAI) prevalence in 9 hospitals in Jacksonville, Florida; to evaluate the performance of proxy indicators for HAIs; and to refine methodology in preparation for a multistate survey. DESIGN Point prevalence survey. PATIENTS Acute care inpatients of any age. METHODS HAIs were defined using National Healthcare Safety Network criteria. In each facility a trained primary team (PT) of infection prevention (IP) staff performed the survey on 1 day, reviewing records and collecting data on a random sample of inpatients. PTs assessed patients with one or more proxy indicators (abnormal white blood cell count, abnormal temperature, or antimicrobial therapy) for the presence of HAIs. An external IP expert team collected data from a subset of patient records reviewed by PTs to assess proxy indicator performance and PT data collection. RESULTS Of 851 patients surveyed by PTs, 51 had one or more HAIs (6.0%; 95% confidence interval, 4.5%-7.7%). Surgical site infections ([Formula: see text]), urinary tract infections ([Formula: see text]), pneumonia ([Formula: see text]), and bloodstream infections ([Formula: see text]) accounted for 75.8% of 58 HAIs detected by PTs. Staphylococcus aureus was the most common pathogen, causing 9 HAIs (15.5%). Antimicrobial therapy was the most sensitive proxy indicator, identifying 95.5% of patients with HAIs. CONCLUSIONS HAI prevalence in this pilot was similar to that reported in the 1970s by the Centers for Disease Control and Prevention's Study on the Efficacy of Nosocomial Infection Control. Antimicrobial therapy was a sensitive screening variable with which to identify those patients at higher risk for infection and reduce data collection burden. Additional work is needed on validation and feasibility to extend this methodology to a national scale.

Abstract
BACKGROUND Just two decades ago, 30 of today's countries in Europe and Asia had socialist governments under Soviet dominance or direct administration. Intensive health system reforms have altered infection control in many of these countries. However, much of the literature from these countries is difficult to access by international scientists. AIM To summarize existing infection control policies and practices in post-Soviet Bloc countries. METHODS In addition to PubMed and Google search engines, we explored local websites and grey literature. In total, 192 references published in several languages were reviewed. FINDINGS Infection control in these countries is in the midst of transition. Three groups of countries were identified. First, Eastern European and Baltic countries building surveillance systems for specific pathogens and antibiotic use; second, European post-Soviet Bloc countries focusing on the harmonization of recently established infection control infrastructure with European surveillance programmes; third, countries such as those formerly in the Union of Soviet Socialist Republics, Mongolia and post-conflict Eastern European countries that are in the first stages of reform. Poor commitment, resource scarcity and shortages of expertise were identified. Underreporting of official infection control statistics is widespread. CONCLUSIONS Guidance from international organizations has been crucial in initiating and developing contemporary infection control programmes. More support from the international community will be needed for the third group of countries, where infection control has remained a neglected issue.

Abstract
AIM To compare point prevalence surveys of healthcare-associated infections (HCAI) performed in 2003, 2005 and 2007 in half of the acute care hospitals in Lithuania. FINDINGS The prevalence of HCAI decreased slightly from 2003 to 2007 (from 4.3% to 3.4%). The rate decreased for each surveyed year in intensive care, surgical and paediatric units, and increased in rehabilitation-nursing units. The proportion of lower respiratory tract infections increased (from 26.3% to 32.3%), while the proportion of urinary tract infections and bloodstream infections decreased (from 11.6% to 6.7% and from 8.9% to 2.3%, respectively). The proportion of microbiologically investigated HCAI cases decreased from 2003 to 2007 (from 56.0% to 41.0%, P<0.02). Gram-positive organisms accounted for most cases of HCAI. Approximately one-third of patients were on antimicrobial therapy (31.1%, 29.3% and 32.1% in 2003, 2005 and 2007, respectively), including penicillins, broad-spectrum penicillins, first-/second-generation cephalosporins and aminoglycosides. CONCLUSION Repeated surveys allowed determination of trends in HCAI prevalence, risk factors and antibiotic usage. The surveys established infection control priorities in Lithuania, and resulted in changes to the national HCAI surveillance system.

Abstract
Background Nosocomial infections are one of the most serious complications in intensive care unit patients because they lead to high morbidity, mortality, length of stay and cost. The aim of this study was to determine the nosocomial infections, risk factors, pathogens and the antimicrobial susceptibilities of them in intensive care unit of a university hospital. Material/Methods The patients were observed prospectively by the unit-directed active surveillance method based on patient and the laboratory. Results 20.1% of the patients developed a total of 40 intensive care unit-acquired infections for a total of 988 patient-days. The infection sites were the lower respiratory tract, urinary tract, bloodstream, wound, and the central nervous system. The respiratory deficiency, diabetes mellitus, usage of steroid and antibiotics were found as the risk factors. The most common pathogens were Enterobacteriaceae, Staphylococcus aureus, Candida species. No vancomycin resistance was determined in Gram positive bacteria. Imipenem and meropenem were found to be the most effective antibiotics to Enterobacteriaceae. Conclusions Hospital infection rate in intensive care unit is not very high. The diabetes mellitus, length of stay, usage of steroids, urinary catheter and central venous catheter were determined as the risk factors by the final logistic regression analysis. These data, which were collected from a newly established intensive care unit of a university hospital, are important in order to predict the infections and the antimicrobial resistance profile that will develop in the future.

Abstract
OBJECTIVE To assess the overall burden of healthcare-associated infections (HAIs) in patients exposed and nonexposed to surgery. BACKGROUND Targeted HAI surveillance is common in healthcare institutions, but may underestimate the overall burden of disease. METHODS Prevalence study among patients hospitalized in 50 acute care hospitals participating in the Swiss Nosocomial Infection Prevalence surveillance program. RESULTS Of 8273 patients, 3377 (40.8%) had recent surgery. Overall, HAI was present in 358 (10.6%) patients exposed to surgery, but only in 206 (4.2%) of 4896 nonexposed (P < 0.001). Prevalence of surgical site infection (SSI) was 5.4%. Healthcare-associated infections prevalence excluding SSI was 6.5% in patients with surgery and 4.7% in those without (P < 0.0001). Patients exposed to surgery carried less intrinsic risk factors for infection (age >60 years, 55.6% vs 63.0%; American Society of Anesthesiologists score >3,5.9% vs 9.3%; McCabe for rapidly fatal disease, 3.9% vs 6.6%; Charlson comorbidity index >2, 12.3% vs 20.9%, respectively; all P < 0.001) than those nonexposed, but more extrinsic risk factors (urinary catheters, 39.6%vs 14.1%; central venous catheters, 17.8% vs 7.1%; mechanical ventilation, 4.7% vs 1.3%; intensive care stay, 18.3% vs 8.8%, respectively; all P<0.001). Exposure to surgery independently predicted an increased risk of HAI (odds ratio 2.43; 95% CI 2.0–3.0). CONCLUSIONS Despite a lower intrinsic risk, patients exposed to surgery carried more than twice the overall HAI burden than those nonexposed; almost half was accountable to SSI. Extending infection control efforts beyond SSI prevention in these patients might be rewarding, especially because of the extrinsic nature of risk factors.

Abstract
The risk of surgical site infection (SSI) is approximately 1-3% for elective clean surgery. Apart from patient endogenous factors, the role of external risk factors in the pathogenesis of SSI is well recognized. However, among the many measures to prevent SSI, only some are based on strong evidence, for example, adequate perioperative administration of prophylactic antibiotics, and there is insufficient evidence to show whether one method is superior to any other. This highlights the need for a multimodal approach involving active post-discharge surveillance, as well as measures at every step of the care process, ranging from the operating theater to postoperative care. Multicenter or supranational intervention programs based on evidence-based guidelines, 'bundles' or safety checklists are likely to be beneficial on a global scale. Although theoretically reducible to zero, the maximal realistic extent by which SSI can be decreased remains unknown.

Abstract
Health statistics of Mongolia indicate that hospital-acquired infections (HAIs) occur in 0.01-0.05% of all hospital admissions. This is considerably lower than internationally reported rates. A one-day survey was conducted in two tertiary hospitals of Ulaanbaatar in September 2008 to estimate HAI prevalence, associated risk factors and patterns of antibiotic usage. Among 933 patients surveyed, 50 (5.4%) were diagnosed with HAI. Prevalence of surgical site infection was 1.1% (3.9% among surgical patients), bloodstream infection 0.3%, respiratory tract infection 1.3%, urinary tract infection 1.3%, and other HAI 1.4%. Microbiological investigations were only documented for 18.9% of all patients. A total of 558 patients (59.8%) were taking 902 courses of antibiotics; 92.1% of patients were prescribed antibiotics without a sensitivity test. Multiple logistic regression analysis revealed that HAI was significantly associated with the admission source, the hospital, length of hospital stay, surgical and other invasive procedures, urinary catheters and other indwelling devices. The study results were comparable with reports from some other developing countries and confirm that official statistics underestimate the true frequency of HAI in Mongolia.

Abstract
AbstractThe aim of this study was to determine the types nosocomial infections (NIs) and the risk factors for NIs in the central intensive care unit (ICU) of Trakya University Hospital. The patients admitted to the ICU were observed prospectively by the unit-directed active surveillance method based on patient and the laboratory over a 9-month-period. The samples of urine, blood, sputum or tracheal aspirate were taken from the patients on the first and the third days of their hospitalization in ICU; the patients were cultured routinely. Other samples were taken and cultured if there was suspicion of an infection. Infections were considered as ICU-associated if they developed after 48 hours of hospitalization in the unit and 5 days after discharge from the unit if the patients had been sent to a different ward in the hospital. The rate of NIs in 135 patients assigned was found to be 68%. The most common infection sites were lower respiratory tract, urinary tract, bloodstream, catheter site and surgical wound. Hospitalization in ICU for more than 6 days and colonization was found to be the main risk factor for NIs. Prolonged mechanical ventilation and tracheostomy, as well as frequently changed nasogastric catheterization, were found to be risk factors for lower respiratory tract infections. For bloodstream infections, both prolonged insertion of and frequent change of arterial catheters, and for urinary tract infections, female gender, period and repeating of urinary catheterization were risk factors. A high prevalence rate of nosocomial infections was found in this study. Invasive device use and duration of use continue to greatly influence the development of nosocomial infection in ICU. Important factors to prevent nosocomial infections are to avoid long hospitalization and unnecessary device application. Control and prevention strategies based on continuing education of healthcare workers will decrease the nosocomial infections in the intensive care unit.

Abstract
Escherichia coli is the most common cause of urinary tract infection. Elevated blood and urine interleukin-6 (IL-6) levels have been shown in inflammatory urinary tract diseases. The role of IL-6 in mediating the urodynamic dysfunction in response to E. coli-induced urinary tract infection has not yet been fully elucidated. In this study, we investigated the role of IL-6 in the nitric oxide (NO)-triggered alteration of contractile responses in the urinary bladder under an E. coli-induced inflammatory condition. The electrical field stimulation (EFS)-evoked contractions of the isolated detrusor strips, and immunoblotting for detecting protein expression in the bladders was measured short term (1 h) or long term (6 or 24 h) after intraperitoneal injection of E. coli endotoxin (lipopolysaccharide [LPS]) or intravesical instillation of human pyelonephritogenic E. coli-J96 (O4:K6) strain or LPS into mice. IL-6 and NO productions were increased in the urinary bladders of mice 1 to 24 h after LPS or E. coli-J96 treatment. Inducible NO synthase (iNOS) expression and protein kinase C (PKC) activation and EFS-evoked detrusor contractions were increased in the bladders at 6 h after LPS or E. coli-J96 treatment, which could be reversed by anti-IL-6 antibody and iNOS inhibitor aminoguanidine. At 1 h after LPS administration, bladder NO generation, endothelial NOS expression, and EFS-evoked detrusor contractions were effectively increased, whereas anti-IL-6 antibody could not reverse these LPS-induced responses. These results indicate that IL-6 may play an important role in the iNOS/NO-triggered PKC-activated contractile response in urinary bladder during E. coli or LPS-induced inflammation.

Abstract
The objectives of the first national prevalence survey on healthcare-associated infections (HAIs) in Finland were to assess the extent of HAI, distribution of HAI types, causative organisms, prevalence of predisposing factors and use of antimicrobial agents. The voluntary survey was performed during February-March 2005 in 30 hospitals, including tertiary and secondary care hospitals and 10 (25%) other acute care hospitals in the country. The overall prevalence of HAI was 8.5% (703/8234). Surgical site infection was the most common HAI (29%), followed by urinary tract infection (19%) and primary bloodstream infection or clinical sepsis (17%). HAI prevalence was higher in males, among intensive care and surgical patients, and increased with age and severity of underlying illness. The most common causative organisms, identified in 56% (398/703) of patients with HAIs, were Escherichia coli (13%), Staphylococcus aureus (10%) and Enterococcus faecalis (9%). HAIs caused by multi-resistant microbes were rare (N = 6). A total of 122 patients were treated in contact isolation due to the carriage of multi-resistant microbes. At the time of the survey, 19% of patients had a urinary catheter, 6% central venous line and 1% were ventilated. Antimicrobial treatment was given to 39% of patients. These results can be used for prioritising infection control measures and planning more detailed incidence surveillance of HAI. The survey was a useful tool to increase the awareness of HAI in participating hospitals and to train infection control staff in diagnosing HAIs.

Abstract
Healthcare-associated infection is a major safety issue affecting the quality of care of hundreds of millions of patients every year in both developed and developing countries. To meet the goal of ensuring patient safety across healthcare settings around the globe, the World Health Organization launched the World Alliance for Patient Safety in October 2004. Healthcare-associated infections were identified as a fundamental work priority and selected as the topic of the First Global Patient Safety Challenge launched by the Alliance. Under the banner "Clean Care is Safer Care", the Challenge aims at implementing several actions to reduce healthcare-associated infections worldwide, regardless of the level of development of healthcare systems and the availability of resources. Implementation strategies include the integration of multiple interventions in the areas of blood safety, injection safety, clinical procedure safety, and water, sanitation and waste management, with the promotion of hand hygiene in healthcare as the cornerstone. Several initiatives have been undertaken to raise global awareness and to obtain country commitment to support action on this issue. The new Guidelines on Hand Hygiene in Health Care, including the most consistent scientific evidence available, have been issued in an advanced draft form. An implementation strategy is proposed therein to provide solutions to overcome obstacles to improvement in compliance with hand hygiene practices, together with a range of practical tools for use in healthcare settings. The latter are currently undergoing testing in several pilot sites to evaluate feasibility, acceptability and sustainability.

Abstract
BACKGROUND Infection control and hospital-acquired infection (HAI) prevalence reports from developing countries are often not well established because of the lack of staff and resources. The aim of this study was to estimate the prevalence of HAI in a Moroccan hospital as well as to identify its predisposing factors. METHODS A one-day prevalence survey was conducted in April 2005 at Ibn Sina University Hospital which included all inpatients who had been in the hospital for at least 48 hours. RESULTS Among 658 patients surveyed, the prevalence of HAI was 17.8%. The prevalence was higher in intensive care units (50%). The most frequently infected sites were urinary tract (35%) and surgical wounds (32.5%). Microbiological documentation was available in only 31.6% of HAIs. The most frequently isolated organisms were Staphylococcus aureus (30%) and Proteus mirabilis (25%). Results of multiple logistic regression analysis indicated that HAI is linked to the surgical category, a hospital stay of more than 10 days, and the use of intravascular and urinary devices. CONCLUSIONS The prevalence of HAI is high at our center. This survey provided the principal information for future surveillance and prevention programs in Morocco.

Abstract
Hospital-acquired pneumonia (HAP) is the most common healthcare-acquired infection contributing to death. Effective management requires accurate diagnosis, administration of a suitable antibiotic regimen early in infection and implementation of prevention strategies. In recent years, there has been a rapid increase in the number of country-specific HAP guidelines in Europe, which vary in their formulation, coverage of different disease aspects and overall recommendations. Development of comprehensive pan-European HAP guidelines would rationalize the conflicting proposals, provide a useful resource and limit guideline proliferation. However, careful consideration needs to be given to the principles of guideline development to ensure that the output is rigorous, broadly applicable and facilitates update as new data becomes available. The use of an evidence-based approach to HAP guideline development is optimal, but is compromised by limitations in the supporting data. The implementation of a formalized evidence grading system is key to introducing consistency into the guideline development process. Pan-European guidelines should provide recommendations on core aspects of HAP common to all treatment settings and locations, and reflect the differing perspectives of the countries involved. Given the different antibiotic susceptibility profiles across Europe, such guidelines should provide general treatment recommendations suitable for local adaptation. The development of such guidelines represents an ideal time to identify priorities for European research, by addressing controversies and identifying previously unconsidered aspects of HAP. Establishing a pan-European consensus on core processes of care should be viewed as an impetus for change to improve clinical practices and should include a suitable implementation strategy.

Abstract
A point-prevalence survey of five European university hospitals was performed to benchmark antimicrobial drug use in order to identify potential problem areas in prescribing practice and to aid in establishing appropriate and attainable goals. All inpatients at the university hospitals of Rijeka (Croatia), Tartu (Estonia), Riga (Latvia), Vilnius (Lithuania) and Karolinska-Huddinge (Sweden) were surveyed for antimicrobial drug use during a single day. The frequency of antimicrobial drug use was 24% in Rijeka, 30% in Tartu, 26% in Riga, 14% in Vilnius and 32% in Huddinge. Surgical patients were treated with antimicrobial agents more often than medical patients in Riga (53% vs. 31%), Tartu (39% vs. 26%) and Vilnius (54% vs. 25%). Two-thirds of patients in Rijeka, Tartu, Riga and Vilnius, and fewer than half of the patients in Huddinge, received antimicrobial agents intravenously. Broad-spectrum antimicrobial agents were used most commonly in Rijeka. The prevalence of nosocomial infections treated with antibiotics was 9% at Huddinge, and 3-5% at the other centres. Benchmarking antimicrobial drug use at five university hospitals identified differences and problem areas. The high rates of intravenous administration, poor compliance with guidelines, and prolonged surgical prophylaxis were general problems that deserved specific attention at all centres. A change in prescription practices may reduce unnecessary drug use and decrease antimicrobial resistance.

Abstract
OBJECTIVE The purpose of this study was to provide a national estimate of the number of healthcare-associated infections (HAI) and deaths in United States hospitals. METHODS No single source of nationally representative data on HAIs is currently available. The authors used a multi-step approach and three data sources. The main source of data was the National Nosocomial Infections Surveillance (NNIS) system, data from 1990-2002, conducted by the Centers for Disease Control and Prevention. Data from the National Hospital Discharge Survey (for 2002) and the American Hospital Association Survey (for 2000) were used to supplement NNIS data. The percentage of patients with an HAI whose death was determined to be caused or associated with the HAI from NNIS data was used to estimate the number of deaths. RESULTS In 2002, the estimated number of HAIs in U.S. hospitals, adjusted to include federal facilities, was approximately 1.7 million: 33,269 HAIs among newborns in high-risk nurseries, 19,059 among newborns in well-baby nurseries, 417,946 among adults and children in ICUs, and 1,266,851 among adults and children outside of ICUs. The estimated deaths associated with HAIs in U.S. hospitals were 98,987: of these, 35,967 were for pneumonia, 30,665 for bloodstream infections, 13,088 for urinary tract infections, 8,205 for surgical site infections, and 11,062 for infections of other sites. CONCLUSION HAIs in hospitals are a significant cause of morbidity and mortality in the United States. The method described for estimating the number of HAIs makes the best use of existing data at the national level.

Abstract
Protein-energy malnutrition and nosocomial infection (NI) are frequent in elderly patients, and a causal link between the two has often been suggested. The aim of the present study was to identify the nutritional parameters predictive of NI in elderly patients. We assessed on admission 101 patients (sixty-six women, thirty-five men, aged over 65 years) admitted to an acute care of the elderly department. Sarcopenia was detected by dual-energy X-ray absorptiometry, with appendicular skeletal muscle mass expressed with respect to body area. Weight, BMI, albuminaemia, serum transthyretin and C-reactive protein values were also determined on admission, and known risk factors, such as functional dependence and invasive biomedical material, were also evaluated. After up to 3 weeks of hospitalisation, patients were classified according to whether they had developed an NI. After 3 weeks of hospitalisation, we found that twenty-nine patients had suffered an NI, occurring after a mean of 16.1 d. Patients who were sarcopenic on admission had a significantly higher risk of contracting an NI (relative risk 2.1, 95 % CI 1.1, 3.8). None of the other morphometric or biological parameters differed significantly between the two groups of patients on admission. Patients who experienced an NI were also more likely, on admission, to have a medical device (P=0.02 to P=0.001 depending on the device), to have swallowing problems (P=0.002) or to have restricted autonomy (P<0.01). Sarcopenia on admission to an acute care of the elderly unit, as measured by X-ray absorptiometry, was therefore associated with a doubled risk of NI during the first 3 weeks of hospitalisation.
