Abstract
Healthcare-associated infection is one of the most common and severe threats to patients' health and remains a significant challenge for healthcare providers. Among healthcare-associated infections, urinary tract infection (UTI) is one of the most common infections. This study aimed to determine the global incidence of UTI among patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline was used to perform this systematic review and meta-analysis. The articles were searched from April 4 to August 5, 2022, from electronic databases (Scopus, PubMed, Web of Science, Google Scholar, DOAJ, and MedNar) using Boolean logic operators, MeSH terms, and keywords. The quality of the study was assessed using the JBI Critical Assessment tool. One thousand nine ninety three articles were retrieved from the electronic databases, of which 38 articles conducted on 981 221 patients were included in the current study. The study found the global pooled incidence of UTI accounted for 1.6%. Based on the subgroup analysis by survey period and WHO region, the highest incidence of UTI was reported in the African Region [3.6%] and among studies conducted between 1996 and 2001 [3.7%]. This study revealed the overall pooled incidence of UTI was 1.6%. The highest incidence of UTI (3.6%) was reported in the African region. This indicates that there is a need to implement safety measures.

Chua WC, Rahman SA, Deris ZZ. Prevalence, Risk Factors and Microbiological Profile of Orthopaedic Surgical Site Infection in North-Eastern Peninsular Malaysia. Malays Orthop J 2022; 16:94-103.

Abstract
Introduction The devastating outcome of orthopaedic surgical site infections (SSI) are largely preventable if its risk factors, causative organisms and antimicrobial susceptibility patterns in the regional area are known. Materials and methods We conducted a retrospective study to address the lack of epidemiological and microbiological data on orthopaedic SSI in Malaysia. All the 80 patients diagnosed and treated for microbiologically proven orthopaedic SSIs in a tertiary hospital in Malaysia from April 2015 to March 2019 were included in a 1:2 case control study. Results The prevalence of SSI in clean and clean-contaminated surgeries was 1.243%, which is consistent with most of the studies worldwide, but is low compared to other studies done in Malaysia. The most common type of orthopaedics SSI were internal fixation infections (46.25%), superficial SSIs (25.2%) and Prosthetic joint infections (18.75%). Obesity and tobacco use were found to be significant risk factors of orthopaedic SSI. The most common perioperative prophylaxis used was IV cefuroxime. Majority of the cases (86.5%) received prolonged prophylactic antibiotics. The most common causative agent was Staphylococcus aureus (31.25%), followed by Pseudomonas aeruginosa (26.25%) and Enterobacter spp (7.5%). Methicillin-resistant Staphylococcus aureus (MRSA) accounted for 20% of the S. aureus infections. Up to 19.4% of the Gram-negative organisms are multidrug resistant. The higher rate of isolation of organisms resistant to the prophylactic antibiotics being used may be related to the prolonged use of prophylactic antibiotics, which exerted selective pressure for the acquisition of resistant organisms. Conclusion Despite its relatively low prevalence in our local institution and worldwide, the prevention of SSI in orthopaedic practice is crucial to avoid morbidity, mortality and high healthcare cost. This may be achieved by control of modifiable risk factors such as obesity and tobacco use, appropriate use of prophylactic antibiotics and implementation of good surgical and infection control practices.

Correlating incidence densities and point-prevalence for the surveillance of catheter-associated urinary tract infections. Am J Infect Control 2020; 48:1393-1395. [PMID: 32057508 DOI: 10.1016/j.ajic.2020.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 01/07/2020] [Accepted: 01/08/2020] [Indexed: 11/23/2022]
Abstract
We aimed to validate the use of point-prevalence to identify catheter-associated urinary tract infections against the gold standard of incidence densities. We did not find a significant association, and hence our findings do not support the common practice of using point-prevalence as a less resource intensive method for catheter-associated urinary tract infections surveillance.

Vitamin C in the Presence of Sub-Inhibitory Concentration of Aminoglycosides and Fluoroquinolones Alters Proteus mirabilis Biofilm Inhibitory Rate. Antibiotics (Basel) 2019; 8:antibiotics8030116. [PMID: 31405233 PMCID: PMC6783857 DOI: 10.3390/antibiotics8030116] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 08/06/2019] [Accepted: 08/08/2019] [Indexed: 11/29/2022] Open
Abstract
Vitamin C has antimicrobial activity and is often used as an oral supplement accompanying antibiotic treatment in urinary tract infections (UTI). Proteus mirabilis is the third common species responsible for UTIs that are mostly treated with fluoroquinolones or aminoglycosides. Treatment of the UTI caused by P. mirabilis is problematic due to the ability to form biofilm on the urinary catheters. The aim of the study was to evaluate the influence of ascorbic acid in combination with antibiotics on P. mirabilis abilities to form biofilm. The susceptibility of P. mirabilis reference strain ATCC® 29906™ and four clinical strains isolated from the urine samples of patients with urinary catheter were evaluated according to EUCAST recommendations. The influence of ascorbic acid (0.4 mg × mL−1) in combination with antibiotics on biofilm formation was evaluated spectrophotometrically. Aminoglycosides at sub-inhibitory concentrations more successfully limited biofilm formation by P. mirabilis strains without ascorbic acid addition. Inhibition rate differences at the lowest concentrations of gentamicin and amikacin were statistically significant (p ≤ 0.05). Ascorbic acid addition to the culture medium limited the inhibitory effect of fluoroquinolones, facilitating biofilm formation by P. mirabilis strains. The addition of ascorbic acid during aminoglycosides therapy may disturb treatment of urinary tract infections related to the presence of P. mirabilis biofilm.

Abstract
Health-care-associated infections (HAIs) are considered a serious public health issues that contribute substantially to the global burden of mortality and morbidity with respect to infectious diseases. The aim is to assess the burden of health-care-associated infections by collation of available data from published point prevalence surveys (PPS) on HAIs to give future guidance. Study protocol and methodology were designed according to preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Published research papers that conducted a point prevalence survey of HAIs in hospital settings by following the structured survey methodology employed by European Centre of Disease Prevention and Control (ECDC) were included. Of 1212 articles, 67 studies were included in the final analysis conducted across different countries. Overall, 35 studies were conducted in Europe, 21 in Asia, 9 in America, and 2 in Africa. The highest prevalence of HAIs was recorded in a study conducted in adult ICU settings of 75 regions of Europe (51.3%). The majority of the studies included HAI data on urinary tract infections, respiratory tract infections, and bloodstream infections. Klebsiella pneumonia, Pseudomonas aeruginosa and E. coli were the most frequent pathogens responsible for HAIs. PPS is an useful tool to quantify HAIs and provides a robust baseline data for policymakers. However, a standardize surveillance method is required. In order to minimize the burden of HAIs, infection prevention and control programs and antibiotic stewardship may be effective strategies to minimize the risk of HAIs.

Abstract
BACKGROUND Surgical site infection (SSI) is both the most frequently studied healthcare-associated infection and the most common healthcare-associated infection in the developing world. A systematic review and meta-analysis was conducted to evaluate the relative size of this burden and to estimate the prevalence of SSI in clean and clean-contaminated surgeries in a large sample of countries in the developing world. METHODS A systematic search of the MEDLINE/PubMed, Scopus, and LILACS databases was conducted to identify studies providing the prevalence of SSI in elective clean and clean-contaminated surgeries in 39 countries or regions around the world. Data of interest were limited to publications from January 2000 to December 2017. Studies with information on the number of cases of SSI and number of total elective clean and clean-contaminated surgeries during the same period were included in this evaluation. Studies lacking clear definition of the total number of exposed patients were excluded. RESULTS Based on the combined data from the 99 articles evaluated in this analysis, the overall prevalence of SSI in elective clean and clean-contaminated surgeries was estimated to be 6% (95% confidence interval (CI) 5-7%). This increased to 15% (95% CI 6-27%) when considering only those reports with post-discharge surveillance data. The overall prevalence of SSI in Africa/Middle East, Latin America, Asia, and China was 10% (95% CI 6-15%), 7% (95% CI 5-10%), 4% (95% CI 4-5%), and 4% (95% CI 2-6%), respectively. Significant variability in the data was confirmed by both the funnel plot and the Egger test (p=0.008). CONCLUSIONS Although the data are variable, it is clear that the incidence of SSI in the developing world is higher than that in the developed world.

Abstract
Globally, pneumonia is considered to be the biggest killer of infants and young children (aged <5 years) outside the neonatal period, with the greatest disease burden in low- and middle-income countries. Optimal management of childhood pneumonia is challenging in settings where clinicians have limited information regarding the local pathogen and drug resistance profiles. This frequently results in unnecessary and poorly targeted antibiotic use. Restricting antibiotic use is a global priority, particularly in Asia and the Western Pacific Region where excessive use is driving high rates of antimicrobial resistance. The authors conducted a comprehensive literature review to explore the antibiotic resistance profile of bacteria associated with pneumonia in the Western Pacific Region, with a focus on Vietnam. Current management practices were also considered, along with the diagnostic dilemmas faced by doctors and other factors that increase unnecessary antibiotic use. This review offers some suggestions on how these issues may be addressed.

Abstract
BACKGROUND Point-prevalence studies can identify priorities for infection control. AIM In May 2014, the Beijing Nosocomial Infection Control and Quality Improvement Centre organized a point-prevalence survey in 124 acute care hospitals in Beijing province. By analysing the survey results and factors affecting the point prevalence of healthcare-associated infections (HCAIs) in secondary and tertiary acute care hospitals in a certain area of China, this study provides evidence and reference to monitor HCAIs in a wide variety of hospitals. METHODS An epidemiological cross-sectional survey conducted by infection control practitioners was used to assess the point-prevalence rate of HCAIs by reviewing cases and performing bedside surveys. FINDINGS In total, 124 hospitals and 61,990 patients were surveyed, and 1389 (2.2%) HCAIs were diagnosed in 1294 (2.1%) patients. Respiratory tract infections were the most common HCAIs (54.4%, 51.7-56.9%), followed by urinary tract infections (15.0%, 13.2-16.9%), gastrointestinal tract infections (7.7%, 6.3-9.1%), surgical site infections (6.3%, 5.1-7.6%) and bloodstream infections (5.5%, 4.3-6.8%). In this survey, the top three pathogens were Pseudomonas aeruginosa, Acinetobacter baumannii and Escherichia coli. Rates of central vein catheter insertion, urethral catheterization and mechanical ventilation were 9.9%, 12.4% and 3.8%, respectively. Overall, 23.7% of the patients underwent surgery on or before the date of the survey. HCAIs were present in 14.5% of intensive care unit patients, 2.3% of medical patients and 2% of surgical patients. Diarrhoea was found in 0.8% of the assessed cases; however, tests for Clostridium difficile are not routinely available in China. CONCLUSION In areas with limited personnel and resources, regular investigation of the point prevalence of HCAIs can be performed in lieu of comprehensive monitoring to elucidate risk factors and disease burdens of HCAIs.

Abstract
The objective of this study was to determine the rate, independent risk factors, and outcomes of healthcare-associated infections in pediatric patients. This study was performed between 2011 and 2014 in pediatric clinic and intensive care unit. 86 patients and 86 control subjects were included in the study. Of 86 patients with nosocomial infections (NIs), there were 100 NIs episodes and 90 culture growths. The median age was 32.0 months. The median duration of hospital stay of the patients was 30.0 days. The most frequent pathogens were Coagulase-negative Staphylococcus, Acinetobacter spp., Klebsiella spp., and Candida spp. Unconsciousness, prolonged hospitalization, transfusion, mechanical ventilation, use of central venous catheter, enteral feeding via a nasogastric tube, urinary catheter, and receiving carbapenems and glycopeptides were found to be significantly higher in NIs patients. Multivariate logistic regression analysis showed prolonged hospitalization, neutropenia, and use of central venous catheter and carbapenems as the independent risk factors for NIs. In the univariate analysis, unconsciousness, mechanical ventilation, enteral feeding, use of enteral feeding via a nasogastric tube, H2 receptor blockers, and port and urinary catheter were significantly associated with mortality. In the multiple logistic regression analysis, only mechanical ventilation was found as an independent predictor of mortality in patients with NIs.

Abstract
BACKGROUND Acinetobacter baumannii strains co-producing carbapenemase and 16S rRNA methylase are highly resistant to carbapenems and aminoglycosides. METHODS Ninety-three isolates of multidrug-resistant A. baumannii were obtained from an intensive care unit in a hospital in Vietnam. Antimicrobial susceptibility tests and whole genome sequencing were performed. Multilocus sequence typing and the presence of drug resistant genes were determined and a maximum-likelihood phylogenetic tree was constructed by SNP alignment of whole genome sequencing data. RESULTS The majority of isolates belonged to clonal complex 2 (ST2, ST570 and ST571), and carried carbapenemase encoding genes bla OXA-23 and bla OXA-66. Two isolates encoded carbapenemase genes bla NDM-1 and bla OXA-58 and the 16S rRNA methylase encoding gene armA and did not belong to clonal complex 2 (ST16). CONCLUSION A. baumannii isolates producing 16S rRNA methylase ArmA and belonging to clonal complex 2 are widespread, and isolates co-producing NDM-1 and ArmA are emerging, in medical settings in Vietnam.

Abstract
A systematic infection control program is found to be an important tool to reduce hospital-associated infections (HAIs) and surveillance of infection is a significant part of it. The aim of this paper was to present the result from 17 years continuous prevalence studies after implementation of a systematic infection control program, to examine trends of hospital-associated infections and to study possible risk factors for different sites of infection. Data from 61399 in-patients at Haukeland University Hospital, Norway, from 1994 to 2010 was included in the study. Overall prevalence of HAIs was 7.6%. There was a reduction in HAIs from 8.3% in 1994 to 7.1% in 2010 (relative decrease 14.4%), mostly attributable to a significant reduction in the prevalence of urinary tract infections (UTI). For surgical site infections (SSI) we found a borderline significant increase (p=0.05). Male gender (except for UTI), urinary tract catheter and surgical operation were all strong predictors for HAIs. Higher age was a risk factor for all infection types, except for BSI. In conclusion, repeated prevalence surveys demonstrated a significant reduction in HAIs but no decrease in hospital-associated BSI, LRTI and SSI. There was, however, a rapid decline of UTI and other less severe HAIs.

Abstract
OBJECTIVE To study the pathogen distribution, antimicrobial susceptibility and risk factors of postoperative nosocomial infections among children with congenital heart disease. METHODS Three hundreds children with congenital heart disease admitted to our hospital to receive surgeries from February 2010 to February 2013 were selected. RESULTS A total of 120 children were tested as positive by sputum culture, with the infection rate of 40.0%. The top five most common pathogenic microorganisms included Staphylococcus epidermidis, Staphylococcus aureus, Enterococcus, Pseudomonas aeruginosa, and Candida albicans. S. epidermidis, S. aureus and Enterococcus were highly resistant to penicillin, azithromycin and erythromycin, moderately susceptible to levofloxacin and cefazolin, and completely susceptible to vancomycin. Multivariate Logistic regression analysis showed that hospitalization stay length, combined use of antibiotics, systemic use of hormones, mechanical ventilation and catheter indwelling were the independent risk factors of postoperative nosocomial infections (P<0.05). CONCLUSION Nosocomial infection, which was the most frequent postoperative complication of pediatric congenital heart disease, was predominantly induced by Gram-positive bacteria that were highly susceptible to cephalosporins and vancomycin. Particular attention should be paid to decrease relevant risk factors to improve the prognosis.

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
Antibiotic use is the driving force for increasing antibiotic resistance. A large proportion of antibiotics in hospitals are used inadequately. The objective of this study was to evaluate antibiotic use at the Hospital for Infectious Diseases through point-prevalence surveys conducted in 2006, 2008, and 2009. Point prevalence surveys were part of the European Surveillance on Antimicrobial Consumption (ESAC) Hospital Care Subproject and patients' data were collected following ESAC protocol. Additionally, the adequacy of antimicrobial therapy and administration of the first line antibiotic according to the local guidelines were assessed by an infectious disease doctor and a clinical microbiologist. In the study period among the 599 patients admitted to hospital, 352 (58·8%) received antibiotics. Out of 448 antimicrobial treatments, 313 (69·9%) were administered parenterally and 135 (30·1%) orally. Altogether in years 2006, 2008, and 2009 the most commonly prescribed antibiotics were ceftriaxone (19·9%), co-amoxiclav (15·4%), ciprofloxacin (12·3%), narrow spectrum penicillins (6·5%), and penicillinase resistant penicillins (5·6%). Most (82·6%) of the treated infections were community acquired infections. The predominating diagnoses were urinary tract infections and infections with no primary site defined, followed by skin, soft tissue and bone and joint infections. The overall adequacy of antimicrobial therapy was 82% and the first line antibiotic according to the local guidelines was administered with high frequency for central nervous system and cardiovascular infections (100%), and low for ear, nose, and throat infections, urinary tract infections, lower respiratory tract and bone and joint infections (23·0%, 51·6%, 52·5%, 65·0%, respectively) which indicates a significant overuse of antibiotics for diagnoses listed. The results of an individual point prevalence survey provided reliable and representative data for the hospital. Point-prevalence surveys proved to be a valuable method for detecting targets for antibiotic prescribing improvement and they clearly showed that our local hospital guidelines offered too many choices of antibiotic treatment for each clinical indication and needed revision.

Abstract
Background 16S rRNA methylase-producing Gram-negative bacteria are highly resistant to all clinically important aminoglycosides. We analyzed clinical strains of 16S rRNA methylase-producing Acinetobactor baumannii and Pseudomonas aeruginosa obtained from clinical isolates in medical settings in Vietnam. Methods From 2008 to 2011, 101 clinical strains of A. baumannii and 15 of P. aeruginosa were isolated from patients in intensive care units (ICUs) in two medical settings in Vietnam. Antimicrobial susceptibilities were determined using the microdilution method and epidemiological analysis was performed by pulsed-field gel electrophoresis and MLST. Genes encoding the 16S rRNA methylases, OXAs and CTX-Ms were analyzed by PCR and sequence analysis. Results 16S rRNA methylase-producing Gram-negative pathogens were detected in two hospitals in Vietnam. Of the 101 clinical isolates of A. baumannii and the 15 of P. aeruginosa isolated from two ICUs in these hospitals, 72 (71.3%) were highly resistant to amikacin, arbekacin and gentamicin, with MICs greater than 1,024 mg/L. The 16S rRNA methylases ArmA and RmtB were produced by 61 and 9 isolates of A. baumannii, respectively, and RmtB was produced by 2 isolates of P. aeruginosa. Moreover, 52 of the A. baumannii isolates producing 16S rRNA methylases harbored both blaOXA-23-like and blaOXA-51-like genes. Most A. baumannii isolates producing 16S rRNA methylase obtained in hospital A in Hanoi were ST91 and ST231, whereas most from hospital B in Ho Chi Minh City were ST136, ST195, and ST254. The two P. aeruginosa isolates harboring rmtB showed different patterns on PFGE, one each corresponding to ST217 and ST313. Conclusions Gram-negative bacteria producing the 16S rRNA methylases ArmA and RmtB are emerging in medical settings in Vietnam. A. baumannii isolates in northern and southern regions of Vietnam may be of different lineages.

Abstract
PURPOSE Chronic inflammatory processes contribute to the pathogenesis of many age-related diseases. In search of anti-inflammatory foods, we have systematically screened a variety of common dietary plants and mushrooms for their anti-inflammatory activity. METHODS A selection of 115 samples was prepared by a generic food-compatible processing method involving heating. These products were tested for their anti-inflammatory activity in murine N11 microglia and RAW 264.7 macrophages, using nitric oxide (NO) and tumour necrosis factor-α (TNF-α) as pro-inflammatory readouts. RESULTS Ten food samples including lime zest, English breakfast tea, honey-brown mushroom, button mushroom, oyster mushroom, cinnamon and cloves inhibited NO production in N11 microglia, with IC50 values below 0.5 mg/ml. The most active samples were onion, oregano and red sweet potato, exhibiting IC50 values below 0.1 mg/ml. When these ten food preparations were retested in RAW 264.7 macrophages, they all inhibited NO production similar to the results obtained in N11 microglia. In addition, English breakfast tea leaves, oyster mushroom, onion, cinnamon and button mushroom preparations suppressed TNF-α production, exhibiting IC50 values below 0.5 mg/ml in RAW 264.7 macrophages. CONCLUSION In summary, anti-inflammatory activity in these food samples survived 'cooking'. Provided that individual bioavailability allows active compounds to reach therapeutic levels in target tissues, these foods may be useful in limiting inflammation in a variety of age-related inflammatory diseases. Furthermore, these foods could be a source for the discovery of novel anti-inflammatory drugs.

Abstract
UNLABELLED Development of antibiotic resistance in Intensive Care Units (ICUs) is a worldwide problem. The purpose of this study was to evaluate the effect of an antibiotic stewardship program (ASP) by carbapenems restriction on gram-negative antimicrobial resistance in ICU. The study was designed in a 21 bedded general ICU of a teaching hospital with two wings (one and two) in Tehran, Iran. Carbapenem prescription in ICU1 was restricted to only the culture proven multi-drug-resistant bacteria with the absence of sensitivity to other antimicrobial agents. Carbapenem had to be prescribed by a trained ICU physician with close consultation with infectious disease specialist and the clinical pharmacist posted in ICU. Post-prescription reviews and de-escalations were carried out by the same team on regular basis. Restriction policy was commenced in January 2011 in ICU1. All documented infections and resistance patterns of isolated pathogens were recorded in both ICUs during two periods of 6 months before and 9 months after restriction policy implementation. During this study bacterial growth was detected in 51.5% of 1601 samples. Carbapenem administration was decreased from 6.86 to 2.75 DDD/100 patients day (60% decreases) pre-restriction and post-restriction respectively. Significant increase in sensitivity of pseudomonas to imipenem was observed in ICU1 comparing with pre-restriction period six months post restriction (p = 0.000). Sensitivity of Klebsiella and Acinetobacter to imipenem did not change significantly during the study period. CONCLUSION Our study demonstrated that restriction of carbapenems can increase sensitivity of P. aeroginosa to imipenem.

Abstract
BACKGROUND Inappropriate antibiotic prescribing appears to be common worldwide and is contributing to the selection of resistant organisms. This study examined the prevalence of antibiotic prescription and the appropriateness of indications for these prescriptions in 36 representative general hospitals across Vietnam. METHODS A point-prevalence study was performed between February and December 2008. All inpatients on the day of the survey were included in the analysis. Standard published guidelines were used to evaluate the appropriateness of indications for antibiotic prescription. RESULTS On the day of the study, 5,104 of 7,571 patients (67.4%) were receiving antibiotic therapy. The antibiotic prescription rate was highest in surgery wards (93.2%) and lowest in medical wards (48.2%). Of the 5,104 patients receiving antibiotics, the most commonly prescribed agents were cephalosporins (70.2%), penicillins (21.6%), and aminoglycosides (18.9%). Approximately one-third of the patients (1,573 of 5,104) had an inappropriate indication for prescription. Risk factors independently associated with inappropriate indication for antibiotic prescription were seen in hospitals at the national level, obstetrics and gynecology departments, and surgical wards. CONCLUSIONS Our data indicate a high rate of antibiotic use in Vietnamese hospitals, and also a high prevalence of inappropriate indications for antibiotic prescriptions. These findings suggest important areas for intervention and implementation of antibiotic stewardship policies in Vietnamese hospitals.

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
OBJECTIVE The present study investigated regional variations in antibiotic use for the treatment of hospital-acquired infections (HAIs) in France by means of a multilevel analysis, to identify targets for quality improvement. METHODS Data were obtained from the 2001 and 2006 French national point-prevalence surveys of HAIs and antibiotic use. The present study was conducted using data from 393 nonteaching public hospitals. Data included patient characteristics calculated at the hospital level (mean age and proportion of patients with the following: HAI, presence of a vascular catheter, presence of a urinary catheter, surgical procedure, and immunodeficiency) and hospital characteristics (size and presence of an intensive care unit). The regional effect was measured using a random intercept on a regional variable. RESULTS Overall, the prevalence of antibiotic use was 5.35% for both study years. The most commonly used antibiotics for HAIs were fluoroquinolones (2001, 1.33%; 2006, 1.35%) and combinations of penicillins with a β-lactamase inhibitor (2001, 0.92%; 2006, 1.02%). Mapping of antibiotic use showed wide variation between regions. The regional effect explained 3% of antibiotic variation in the unadjusted analysis. In the multivariable analysis, hospital size, high prevalence of patients with immunodeficiency, and infection characteristics explained 45% of the variability in antibiotic use. The regional effect was not retained in the final model. CONCLUSION The pattern of antibiotic use for HAIs differed over time, and regional variations were mostly explained by patient characteristics; there was no regional effect. Models that take data hierarchy into account are essential to better approach antibiotic use and develop relevant strategies for improvement.

Abstract
Catheter-associated urinary tract infection (CAUTI) remains one of the most common types of hospital-acquired infections. Further progress in the prevention of CAUTI requires a better understanding of its pathogenesis. Bacteria may enter the bladder through contamination of the tip during insertion with the flora of the distal urethra or from bacteria ascending the outside or the inside of the catheter. Residual urine in the bladder of catheterised patients increases the risk of bacteriuria. During the process of infection, bacteria need first to adhere to the epithelial cells of the urinary tract and/or the surface of the catheter. They will then develop into biofilms on the catheter surface and are resistant to the immune system and antibiotics. Catheters by themselves may cause immediate physical damage to the bladder epithelium; they may be toxic and also cause inflammation. Bacteria can also damage the epithelium and cause inflammation and the combination of both may be synergistic in producing symptoms in the patient. Most episodes of catheter-associated bacteriuria are asymptomatic but it is not known why some patients are symptomatic and others are not. Further research into the pathogenesis of CAUTI needs to be carried out. A suggestion for the prevention of CAUTI is the use of catheters with an additional eye-hole beneath the balloon to prevent residual urine in the bladder or to remove the tip and balloon altogether, with the additional benefit of having no tip to cause damage or inflammation to the bladder epithelium.

Abstract
BACKGROUND Risk factors for hospital-acquired infection and attributable mortality in surgical and critically ill patients are well-known. We sought to identify factors associated with increased mortality from hospital-acquired infections as compared with community-acquired infections in patients with new-onset fever and a presumed infectious focus (n = 212), in a department of internal medicine. METHODS Demographic, clinical, and laboratory variables were studied for 2 days after inclusion. Septic shock and outcome were monitored for up to 7 and 28 days after inclusion, respectively. RESULTS Of the 212 patients, 54 had hospital-acquired and 158 community-acquired infection, with septic shock rates of 15% and 4% and mortality rates of 24% and 6% (P = .001), respectively. Prior neurologic disease was associated with death. Patients with hospital-acquired infection had more often (intravascular) devices and underwent more often interventions, had a different distribution of infectious foci, and had more often bacteremia. Bacteremia-associated septic shock was associated with nonsurvival in both infection groups. The causative agents were not associated with outcome, and the clinical and laboratory host response associated with nonsurvival generally did not differ among infection groups. CONCLUSION Our data suggest that hospital-acquired infections carry a higher crude mortality rate than community-acquired infection in febrile medical patients, mainly because of more frequent use of devices and hospital interventions and resultant bacteremia and septic shock, rather than by differences in underlying diseases, causative agents, and clinical and laboratory host responses. The observations thus emphasize the continued importance of preventive measures on medical wards of our hospital and can be used for comparison with future studies.
