RESUMEN
A survey was undertaken to evaluate the level of computerization in intensive care units (ICUs) within a French network dedicated to the surveillance of healthcare-associated infections, antimicrobial use (AMU) and antimicrobial resistance (AMR) in ICUs (REA-REZO). Ninety-eight ICUs responded, and patient records were computerized in 57%, antimicrobial prescriptions were computerized in 59% and AMR epidemiology was computerized in 72%. AMU and AMR feedback was provided to the ICU itself for 77% and 65% of ICUs, respectively, and feedback was provided to the national surveillance for 79% and 65% of ICUs, respectively. This study suggests that the level of computerization in ICUs requires further improvement.

PURPOSE: To decrease intensive care unit (ICU)-acquired catheter-related infections (CRI), it is essential that healthcare workers receive training and that quality improvement programmes are in place. The aim of our study was to evaluate risk factors for catheter colonisation and infection, focussing specifically on local care bundles. METHODS: Data were collected prospectively in 51 ICUs [7,188 patients, 8,626 central venous catheters (CVCs)] during two 6-month periods in 2007 and 2008, using a standardized questionnaire on catheter insertion, care and removal. Colonisation and CRI incidence were 6.1 and 2.2/1,000 CVC-days, respectively. A hierarchical mixed logistic model was used to identify risk factors for CRI and colonisation. RESULTS: Written CVC protocols were available in 46 (90 %) ICUs and were strictly followed in 38 ICUs. Factors significantly associated with CRI fell into three overall categories: (1) patient-related factors-immunosuppression [odds ratio (OR) 1.42, p = 0.02], medical diagnosis at admission (OR 1.64, p = 0.03) and trauma patient (OR 2.54, p < 0.001); (2) catheter-related factors-catheter rank (OR 1.7, p < 0.0001, non-subclavian catheter (OR 2.1, p < 0.001) and longer time with the catheter (p < 10(-4)); (3) centre-related factors-quantitative tip culture method (OR 2.55, p = 0.005) and alcohol-based povidone-iodine [OR 0.68, 95 % confidence interval (CI) 0.49-0.96] or alcohol-based chlorhexidine preparations (OR 0.69, 95 % CI 0.34-1.39) as compared to an aqueous povidone-iodine preparation (p < 0.001). CONCLUSIONS: We identified several risk factors for CRI that are amenable to improvement (preference for the subclavian route and use of an antiseptic solution containing alcohol). However, several patient-related factors were also found, and the use of quantitative catheter culture methods increased culture sensitivity, thereby increasing the CRI rate. Case-mix issues and the culture method should be taken into account when assessing the risk of CRI across centres.

Individual and ward risk factors for P. aeruginosa-induced urinary tract infection in the case of nosocomial urinary tract infection in the intensive care unit were determined with hierarchical (multilevel) logistic regression. The 2004-2006 prospective French national intensive care unit nosocomial infection surveillance dataset was used and 3252 patients with urinary tract infection were included; 16% were infected by P. aeruginosa. Individual risk factors were male sex, duration of stay, antibiotics at admission and transfer from another intensive care unit. Ward risk factors were patient turnover and incidence of P. aeruginosa-infected patients.

Pseudomonas aeruginosa is an important pathogen of complicated pneumonia in intensive care units (ICUs). Our objective was to determine 'patient' and 'ward' risk factors for P. aeruginosa pneumonia among patients with nosocomial pneumonia in ICU. Data from the 2004-2006 prospective French national nosocomial infection surveillance in ICUs (REA-RAISIN) were used, including patients admitted for >48 h in ICU and who developed nosocomial pneumonia. Only first pneumonia was considered and categorised as either P. aeruginosa pneumonia or other micro-organism pneumonia. Multilevel logistic regression model (patient as first level and ward as second) with P. aeruginosa pneumonia as binary outcome was performed. Of 3,837 included patients from 201 different wards, 25% had P. aeruginosa pneumonia. P. aeruginosa was significantly more frequent in late onset pneumonia. Higher probability of P. aeruginosa pneumonia was associated with higher age and length of mechanical ventilation, antibiotics at admission, transfer from a medical unit or ICU, and admission in a ward with higher incidence of patients with P. aeruginosa infections. Lower probability of P. aeruginosa was associated with traumatism and admission in a ward with high patient turnover. Our analyses identified a patient's profile and some ward elements that could make suspect P. aeruginosa in case of nosocomial pneumonia.

Non-tuberculous mycobacteria (NTM) infections usually occur in immunocompromised patients but also in immunocompetent patients following invasive procedures, especially for esthetic purposes. Since 2001, 20 episodes (57 cases) of NTM infections, seven of which (43 cases) were related to esthetic care, have been reported to the regional infection control coordinating centers (RICCC), the local health authorities (LHA), and the national institute for public health surveillance. Four notifications (40 cases) were related to non-surgical procedures performed by general practitioners in private settings: mesotherapy, carboxytherapy, and sclerosis of microvaricosities. The three other notifications (three cases) concerned surgical procedures-lifting and mammary prosthesis. Practice evaluations performed by the RICCC and LHA for five notifications showed deficiency of standard hygiene precautions and tap water misuse for injection equipment cleaning, or skin disinfection. Microbiological investigations (national reference center for mycobacteria) demonstrated the similarity of patient and environmental strains: in one episode (16 cases after mesotherapy), M. chelonae isolated from tap water was similar to those isolated from 11 cases. Healthcare-associated NTM infections are rare but have a potentially severe outcome. These cases stress the need of healthcare-associated infection notifications in outpatient settings.

OBJECTIVES: To describe the demographic characteristics, incidence of extra-abdominal hospital-acquired infections and outcome of patients admitted to intensive care unit (ICU) with severe acute pancreatitis. STUDY DESIGN: A retrospective, observational multiple center (65 centers) analysis of prospectively acquired data. PATIENTS AND METHODS: During 2 years, all consecutive admitted patients to ICU for severe acute pancreatitis in the centers participating in the nosocomial infections surveillance network CClin Sud-Est were included. Patients whose ICU stay was less than 48 hours were not included. Demographic characteristics, extra-abdominal hospital-acquired infections and clinical course were described. RESULTS: During the study period, 510 patients were included which represented 2 % of patients with a length of stay longer than 48 hours in the 65 participating ICUs. The global attack rate of extra-abdominal hospital-acquired infections (pneumonia, bacteremia, urinary tract or central venous catheter infection) was 23 % in overall patients and it was 33 % in the 294 mechanically ventilated patients. ICU mortality was 20 % in overall patients and it was 34 % in mechanically ventilated patients. CONCLUSION: Severe acute pancreatitis represents 2 % of ICU stay longer than 48 hours. Its clinical course is frequently complicated by hospital-acquired infections and is associated with an high ICU mortality rate. This epidemiological observational study may be used for calculating sample size for future multicenter interventional therapeutic studies.

BACKGROUND: The prevalence of hospital-acquired Methicillin-resistant Staphylococcus aureus (MRSA) infections shows a huge variety across Europe. Some countries reported a reduction in MRSA frequency, while in others countries increasing MRSA rates have been observed. To reduce the spread of MRSA in the healthcare setting, a sufficient MRSA management is essential. In order to reflect the MRSA management across Europe, MRSA prevention policies were surveyed in ten countries. MATERIALS AND METHODS: The survey was performed by questionnaires in European intensive care units (ICUs) and surgical departments (SDs) in 2004. Questionnaires asked for availability of bedside alcohol hand-disinfection, isolation precautions, decolonization and screening methods. The study was embedded in the Hospital in Europe Link for Infection Control through Surveillance (HELICS) Project, a European collaboration of national surveillance networks. HELICS was initiated in order to harmonize the national surveillance activities in the individual countries. Therefore, HELICS participants developed surveillance modules for nosocomial infections in ICUs and for surgical site infections (SSI). The coordination of this surveillance has now been transferred to the European Centre for Disease Prevention and Control (ECDC). RESULTS: A total of 526 ICUs and 223 SDs from ten countries sent data on organisational characteristics and policies, demonstrating wide variations in care. Substantial variation existed in availability of bedside alcohol hand-disinfection, which was much higher in participating ICUs rather than in SDs (86 vs. 59%). Surveillance cultures of contact patients were obtained in approximately three-fourths of all SDs (72%) and ICUs (75%). Countries with decreasing MRSA proportions showed especially strict implementation of various prevention measures. CONCLUSION: The data obtained regarding MRSA prevention measures should stimulate infection control professionals to pursue further initiatives. Particularly, the vigorous MRSA management in countries with decreasing MRSA proportions should encourage hospitals to implement preventive measures in order to reduce the spread of MRSA.

Surgical-site infections (SSIs) are a key target for nosocomial infection control programmes. We evaluated the impact of an eight-year national SSI surveillance system named ISO-RAISIN (infection du site opératoire - Réseau Alerte Investigation Surveillance des Infections). Consecutive patients undergoing surgery were enrolled during a three-month period each year and surveyed for 30 days following surgery. A standardised form was completed for each patient including SSI diagnosis according to standard criteria, and several risk factors such as wound class, American Society of Anesthesiologists (ASA) score, operation duration, elective/emergency surgery, and type of surgery. From 1999 to 2006, 14,845 SSIs were identified in 964,128 patients (overall crude incidence: 1.54%) operated on in 838 participating hospitals. The crude overall SSI incidence decreased from 2.04% to 1.26% (P<0.001; relative reduction: -38%) and the National Nosocomial Infections Surveillance system (NNIS)-0 adjusted SSI incidence from 1.10% to 0.74% (P<0.001; relative reduction: -33%). The most significant SSI incidence reduction was observed for hernia repair and caesarean section, and to a lesser extent, cholecystectomy, hip prosthesis arthroplasty, and mastectomy. Active surveillance striving for a benchmark throughout a network is an effective strategy to reduce SSI incidence.

This study was performed to evaluate associations between organisational characteristics, routine practices and the incidence densities of central venous catheter-associated bloodstream infections (CVC-BSI rates) in European intensive care units (ICUs) as part of the HELICS project (Hospitals in Europe Link for Infection Control through Surveillance). Questionnaires were sent to ICUs participating in the national nosocomial infection surveillance networks in 2004. The national networks were asked for the CVC-BSI rates of the ICUs participating for the time period 2003--2004. Univariate and multivariate risk factor analyses were performed to identify which practices had the greatest impact on CVC-BSI rates. A total of 526 ICUs from 10 countries sent data on organisational characteristics and practices, demonstrating wide variation in care. CVC-BSI rates were also provided for 288 ICUs from five countries. This made it possible to include 1383444 patient days, 969897 CVC days and 1935 CVC-BSI cases in the analysis. Adjusted logistic regression analysis showed that the categorical variables of country [odds ratio (OR) varying per country from OR: 2.3; 95% confidence interval (CI): 0.5-10.2; to OR: 12.8; 95% CI: 4.4-37.5; in reference to the country with the lowest CVC-BSI rates] and type of hospital 'university' (OR: 2.08; 95% CI: 1.02-4.25) were independent risk factors for high CVC-BSI rates. Substantial variation existed in CVC-BSI prevention activities, surveillance methods and estimated CVC-BSI rates among the European countries. Differences in cultural, social and legal perspectives as well as differences between healthcare systems are crucial in explaining these differences.

The aim of this study was to estimate temporal trends in the incidence of surgical site infection (SSI) using a large SSI surveillance network in southeast France from 1995 to 2003. Data were analysed from 187 surgical wards that had participated in the network for at least two years. The change in SSI rate over time was modelled using a hierarchical logistic regression model with patients clustered within surgical wards. Of the 200 207 patients selected, 3786 (1.9%) had an SSI. The nine-year trend in SSI rate estimated by an odds ratio of 0.95 (95% confidence interval 0.93-0.97) was interpreted as a 5% decrease in SSI rate per year. This decrease was constant over the study period and was observed for almost all of the different types of surgical operations (orthopaedic, gastrointestinal, urology, etc). Overall SSI rates were reduced by 45% over a period of nine years. This trend was maintained even when taking into account the heterogeneity of the surgical wards and the diversity of patient demographics over time. From this, the 5% decrease per year can be reasonably interpreted as a result of preventive measures taken by surgical wards to reduce SSIs.

With the aim of testing the feasibility of a multiresistant bacteria (MRB) surveillance methodology and evaluating the level of antimicrobial resistance and dissemination of resistant pathogens in the Mediterranean area, a pilot study was carried out in nine university hospitals in Algeria, Tunisia and France. The results indicate that third-generation cephalosporin-resistant Enterobacteriaceae comprise the major MRB in Algerian and Tunisian hospitals. In France, the highest incidence rates were found for methicillin-resistant Staphylococcus aureus, while in Tunisian hospitals, imipenem-resistant Acinetobacter baumannii seems to be a particularly prevalent organism. Although the data were not representative of the participating countries as a whole, the results show the importance and ubiquity of the problem in the area and the feasibility of surveillance.

The objectives of this study were to identify the risk factors of nosocomial pulmonary infection (NPI) in intensive care units (ICUs) associated with antimicrobial-resistant bacteria (NPI-ARB) and to compare survival after NPI-ARB with NPI due to antimicrobial-sensitive bacteria (NPI-ASB). We analysed data from a surveillance network monitoring nosocomial infections in 27 mixed ICUs in the south-east of France. NPI surveillance data were recorded for 628 patients with documented NPI. The patients were stratified into 2 groups by type of pneumonia: NPI-ASB (445 patients) vs. NPI-ARB (183 patients). Variables associated with NPI-ARB were identified++ by multivariate logistic regression. Survival was calculated using the Kaplan-Meier method. A medical condition for ICU admission [odds ratio (OR) 1.98, 95% confidence interval (95% CI) 1.35-2.91], transfer from another hospital ward [OR 1.66, 95% CI (1.14-2.42)], a colonized central venous catheter [OR 3.47, 95% CI (1.46-8.21)], a stay of [eight days [OR 1.02, 95% CI (1.01-1. 05)] and mechanical ventilation [OR 2.10, 95% CI (1.31-3.36)] were independent risk factors of NPI-ARB. Median survival was 35 days after NPI-ARB and 32 days after NPI-ASB (P=0.92). Survival after bacterial NPI was not associated with antimicrobial susceptibility.

An analysis of the microbial flora of 10 premature neonates hospitalized in a neonatal intensive care unit (NICU) was made. The babies had received neither antibiotics nor antiseptics and nine out of 10 were born by caesarean section. Samples were collected on the fourth or fifth day of life from 18 skin or mucosal sites. Detailed bacterial counts were obtained by plating out suitable dilutions of the samples on to selective media. Representative samples of each colony type were then subcultured and identified, using standard laboratory methods. Two hundred and fifty-six isolates of staphylococci were obtained and their susceptibility to 23 antibiotics tested. Only 11% of the samples were sterile. Coagulase-negative staphylococci (CNS) were the commonest species isolated and were predominant in every site studied. They were found in 79% of the samples and represented almost 81% of the neonates' flora. Eight species and biotypes of CNS were identified. In decreasing order of frequency, they comprised S. epidermidis (biotypes 1 and 2), S. hominis (biotype 1), S. warneri, S. haemolyticus, S. capitis, S. cohnii and S. hominis (biotype 2). CNS distribution appeared to be highly heterogeneous with no significant specificity of any species for a particular body site. The main quantitative and qualitative variations seemed to relate to the method of delivery, and the intensity and nature of exposure of the neonate to its local environment. A high level of antibiotic resistance was found among the CNS isolates (especially S. epidermidis and S. haemolyticus): penicillin G (96%), oxacillin (31%), erythromycin (52%) and gentamicin (28%). Moreover, multiresistant strains were numerous, supporting the nosocomial origin of CNS.
