BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacterales (ESBLPE) and carbapenemase-producing Enterobacterales (CPE) cause serious infections. Their presence in urine may lead to environmental contamination potentially responsible for cross-transmission. AIM: To evaluate the level of spraying and contamination after emptying urine in the toilet and rinsing in the sink, a common practice in the healthcare setting. METHODS: For each test, the procedure was similar: seat raised, emptying urinal bottle into the toilet at the height of the bowl, rinsing in the sink and flushing. To study splash-drops, water and fluorescein were mixed in the urinal bottle. In each area, the splash-drops frequency and level were assessed with UV. To study contamination, three ESBLPE and one CPE were diluted in saline, 106/mL. Contamination was assessed by sampling before, immediately after and 3 h after the test. The swabs were cultured and the colonies counted and identified. FINDINGS: The areas at the highest risk of spraying were the toilet bowl contour (N = 36/36), the underside of the toilet seat (N = 34) and the inside of the sink (N = 34). Except for gloves (N = 14), there was low clothing contamination. The most frequently contaminated areas were inside the sink (40/48), where the highest levels of contamination were found (14/48). CONCLUSION: Emptying the urinal bottles in the toilet followed by sink rinsing is associated with a significant risk of projection and contamination, depending on the area (highest risk at the sink), but the bacteria did not survive beyond 3 h. This practice, which carries a risk of cross-transmission, should be reviewed.

BACKGROUND: Colonization pressure is a risk factor for intensive care unit (ICU)-acquired multi-drug-resistant organisms (MDROs). AIM: To measure the long-term respective impact of colonization pressure on ICU-acquired extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-PE) and meticillin-resistant Staphylococcus aureus (MRSA). METHODS: All patients admitted to two ICUs (medical and surgical) between January 1997 and December 2015 were included in this retrospective observational study. Rectal and nasal surveillance cultures were obtained at admission and weekly thereafter. Contact precautions were applied for colonized or infected patients. Colonization pressure was defined as the ratio of the number of MDRO-positive patient-days (PDs) of each MDRO to the total number of PDs. Single-level negative binomial regression models were used to evaluate the incidence of weekly MDRO acquisition. FINDINGS: Among the 23,423 patients included, 2327 (10.0%) and 1422 (6.1%) were colonized with ESBL-PE and MRSA, respectively, including 660 (2.8%) and 351 (1.5%) acquisitions. ESBL-PE acquisition increased from 0.51/1000 patient-exposed days (PEDs) in 1997 to 6.06/1000 PEDs in 2015 (P<0.001). In contrast, MRSA acquisition decreased steadily from 3.75 to 0.08/1000 PEDs (P<0.001). Controlling for period-level covariates, colonization pressure in the previous week was associated with MDRO acquisition for ESBL-PE (P<0.001 and P=0.04 for medical and surgical ICU, respectively), but not for MRSA (P=0.34 and P=0.37 for medical and surgical ICU, respectively). The increase in colonization pressure was significant above 100/1000 PDs for ESBL-PE. CONCLUSION: Colonization pressure contributed to the increasing incidence of ESBL-PE but not MRSA. This study suggests that preventive control measures should be customized to MDROs.

Tuberculosis is a human disease caused by Mycobacteriumtuberculosis, and transmitted by airborne pathway. Documented cases of tuberculosis infection in healthcare workers have been reported in both developed and developing countries. Early recognition of potentially infectious cases, immediate implementation of airborne precautions and prompt medical treatment of cases, are required to lower the risk of disease transmission. Molecular biology techniques allow earlier diagnosis. In the event of non-compliance with airborne precautions, the investigation will further have to establish exhaustive lists of potentially exposed healthcare workers and patients, looking for cases of latent tuberculosis infections whose treatment should help avoid active tuberculosis disease.

OBJECTIVES: To conduct an audit of vaccination practices against pertussis in maternity wards to assess immunization practices targeting women, knowledge and awareness among health professionals and their involvement in the vaccination process, and to estimate their vaccine coverage. MATERIALS AND METHODS: 2017 cross-sectional descriptive survey using a data collection sheet of immunization practices targeting women and an anonymous questionnaire for health professionals whose vaccine coverage had been documented by the occupational health service. RESULTS: Five public maternity wards participated: one had a vaccination policy for women; 426 of 822 health professionals completed the questionnaire, 76% (from 50% of all residents to 83% of nurses) declared their vaccination status as up to date. Staff files in occupational health services showed that 69% of 822 health professionals received at least one vaccine booster during adulthood (57% less than 10 years before the survey); documented vaccination coverage rates ranged from 75% for residents to 91% for senior physicians. Occupational physicians and family physicians respectively performed 41% and 34% of vaccinations. While knowledge regarding vaccines was good, only 47% of health professionals declared prescribing them and 18% declared administering the anti-pertussis vaccine "often" or "very often". CONCLUSIONS: Updated data is needed to confirm the reported increase as participating centers are not representative of all birth centers. The active role of health professionals in vaccination-based pertussis prevention needs to be reinforced.

INTRODUCTION: Sternal wound infection (SWI) after cardiac surgery is a severe complication. Among preventive measures, pre-operative decolonization of nasal carriage of Staphylococcus aureus has recently been shown to be beneficial. This quasi-experimental study assessed the effect of decolonization on the incidence of S. aureus-associated SWI based on 19 years of prospective surveillance. METHODS: Segmented negative binomial regression was used to analyse the change over time in the incidence of S. aureus mediastinitis requiring re-operation after cardiac surgery in a French university hospital between 1996 and 2014. Universal nasal decolonization with mupirocin was introduced in December 2001. The association between pre-operative nasal carriage and SWI due to S. aureus was analysed between 2006 and 2012. RESULTS: Among 17,261 patients who underwent a cardiac surgical procedure, 565 developed SWI (3.3%), which was caused by S. aureus in 181 cases (1%). The incidence of mediastinitis caused by S. aureus decreased significantly over the study period (1.43% in 1996-2001 vs 0.61% and 0.64% in 2002-2005 and 2006-2014, respectively; P<0.001). In segmented analysis, there was a significant break in 2002, corresponding to the introduction of decolonization. Despite this intervention, pre-operative nasal carriage remained a significant risk factor for S. aureus mediastinitis (adjusted odds ratio 2.2; 95% confidence interval 1.2-4.2), as were obesity, critical pre-operative status, coronary artery bypass grafting (CABG), and combined surgery with valve replacement and CABG. CONCLUSION: Universal nasal decolonization before cardiac surgery was effective in decreasing the incidence of mediastinitis caused by S. aureus. Nasal carriage of S. aureus remained a risk factor for S. aureus-associated SWI.

OBJECTIVES: Our aim was to evaluate the prevalence and associated factors for carriage of extended-spectrum ß-lactamase-producing enterobacteria (ESBL-PE) in a healthcare facility. METHODS: In 2016 a serial cross-sectional survey of ESBL-PE carriage in a French university hospital was conducted. All patients present on the day of the survey were screened for ESBL-PE carriage. Demographic characteristics and risk factors for ESBL-PE carriage were collected. RESULTS: In all, 146/844 patients (17%) were digestive carriers of ESBL-PE; of these, 96 (66%) had not previously been identified. Among patients carrying ESBL-PE, Escherichia coli (62%) and CTX-M type (94%) predominated. Greater age, recent travel abroad, receipt of antibiotic, and prolonged hospitalization were associated with ESBL-PE carriage. CONCLUSION: Given the high prevalence of ESBL-PE and the high proportion of unknown carriers, our results strongly suggest reinforcing standard precautions rather than contact precautions for controlling the spread of ESBL-PE.

The incidence of surgical site infection (SSI) after cardiac surgery depends on the definition used. A distinction is generally made between mediastinitis, as defined by the US Centers for Disease Control and Prevention (CDC), and superficial SSI. Our objective was to decipher these entities in terms of presentation and risk factors. We performed a 7-year single centre analysis of prospective surveillance of patients with cardiac surgery via median sternotomy. SSI was defined as the need for reoperation due to infection. Among 7170 patients, 292 (4.1%) developed SSI, including 145 CDC-defined mediastinitis (CDC-positive SSI, 2.0%) and 147 superficial SSI without associated bloodstream infection (CDC-negative SSI, 2.1%). Median time to reoperation for CDC-negative SSI was 18 days (interquartile range, 14-26) and 16 (interquartile range, 11-24) for CDC-positive SSI (p 0.02). Microorganisms associated with CDC-negative SSI were mainly skin commensals (62/147, 41%) or originated in the digestive tract (62/147, 42%); only six were due to Staphylococcus aureus (4%), while CDC-positive SSI were mostly due to S. aureus (52/145, 36%) and germs from the digestive tract (52/145, 36%). Risk factors for SSI were older age, obesity, chronic obstructive bronchopneumonia, diabetes mellitus, critical preoperative state, postoperative vasopressive support, transfusion or prolonged ventilation and coronary artery bypass grafting, especially if using both internal thoracic arteries in female patients. The number of internal thoracic arteries used and factors affecting wound healing were primarily associated with CDC-negative SSI, whereas comorbidities and perioperative complications were mainly associated with CDC-positive SSI. These 2 entities differed in time to revision surgery, bacteriology and risk factors, suggesting a differing pathophysiology.

PURPOSE: Surveillance of preventable healthcare associated infections and feedback of the results to clinicians is central in the efforts to improve performance. We assessed Staphylococcus aureus healthcare associated bloodstream infection (HA-BSI) as an indicator of healthcare quality. PATIENTS AND METHOD: Between 2002 and 2012, we carried out a ten-year prospective bedside surveillance of S. aureus healthcare associated bacteraemia in a 940-bed university hospital using standard definitions. RESULTS: Overall, 2784 HA-BSI were identified during the study period, among which 573 (18%) were due to S. aureus. Among these 573 S. aureus bacteraemias, 189 originated from intravascular catheters (32.8%) of which 84% (158/189) in patients outside intensive care units. The proportion of catheter related HA-BSI due to S. aureus was 56% (61/109) in PVC-related HA-BSI and 34% (103/301) in CVC-related HA-BSI. A sharp decrease of PVC-related HA-BSI from 20 to 7 per year was obtained during the same period. CONCLUSION: In our experience, S. aureus HA-BSI is a simple and useful indicator of catheter associated infections, and therefore of healthcare quality, especially in units not covered by other type of surveillance.

We describe the prevalence of carriage and variables associated with introduction of highly drug-resistant microorganisms (HDRMO) into a French hospital via patients repatriated or recently hospitalized in a foreign country. The prevalence of HDRMO was 11% (15/132), with nine carbapenamase-producing Enterobacteriaceae, nine carbapenem-resistant Acinetobacter baumannii and six glycopeptide-resistant enterococci. Half of the admitted patients (63/132, 48%) were colonized with extended spectrum beta-lactamase-producing Enterobacteriaceae (ESBLPE). Among the four episodes with secondary cases, three involved A. baumannii.

OBJECTIVES: The increasing prevalence of extended spectrum beta-lactamase producing enterobacteriaceae (ESBLPE) requires defining the use of carbapenems in first intention. We analyzed the associations between enterobacteriaceae bacteremia (EbBact) and ESBLPE carriage during 10 years in a 950-bed teaching hospital. METHODS: We analyzed a 10-year (July 2001 to June 2011) prospective collection of bacteremia cases including 2 databases: (1) EbBact and (2) a computerized database of patients carrying EBLSE. Only one episode of EbBact was analyzed per patient and hospital stay. Factors associated with ESBLPE bacteremia were assessed by univariate and multivariate logistic regression analysis. RESULTS: Overall, 2355 cases of EbBact were identified, among which 135 (5.7%) were ESBLPE (2001-05: 1.4%, 2006-09: 7.6%, 2010-11: 14.2%). ESBLPE bacteremia was observed in 52 of the 88 (59%) patients carrying ESBLPE and in 83/2267 (3.7%) patients not known to be colonized with ESBLPE. Factors associated with ESBLPE bacteremia in patients not known to be colonized were: female gender (ORa=0.56, CI95% [0.34-0.91]), hospitalization in the ICU (ORa=2.51 [1.27-5.05]) or medical/surgical wards (ORa=1.83 [1.04-3.38]), the period (2006-09, ORa=4.08 [2.21-8.16]; 2010-11, ORa=8.17 [4.14-17.06] compared to 2001-05), and history of EbBact (ORa=2.29 [0.97-4.79]). CONCLUSION: In case of EbBact, patients known to be colonized with ESBLPE present with ESBLPE bacteremia in more than half of the cases, requiring carbapenems as empirical antibiotic treatment. The global prevalence of ESBLPE among patients presenting with EbBact not known to be colonized with ESBLPE was 3.7%.

We performed an 11-year retrospective analysis of consecutive nonduplicate methicillin-resistant Staphylococcus aureus (MRSA) clinical isolates in two neighbouring hospitals in the Paris area. MRSA isolates were classified according to resistance (R) to fluoroquinolones (Fq), kanamycin (K), tobramycin (T) and gentamicin (G). The yearly number of MRSA isolates (3446 in total) decreased, from approximately 350 in 19972002 to 212 in 2007. Four patterns (P) were found: P1 (KTGFq R, n = 776), P2 [KTFq R; G susceptible (S), n = 1630], P3 (Fq R; KTG S, n = 397) and P4 (Fq S; any KTG susceptibility, n = 201). P1 predominated in 1997 (183 isolates) then dropped sharply (nine in 2007); P2 and P4 remained stable over time; and P3 increased from 13 isolates in 1997 to 72 in 2007. Patterns were significantly and positively associated with several variables, independently of the year of collection: P1, age < 80 years, male gender, intensive care unit stay, and hospital onset; P3, age > 80 years and stay in intermediate or long-term care wards; and P4, age < 40 years, stay in an obstetric ward, and imported cases. Molecular typing of 79 isolates in 2005 and 2007 using multilocus sequence typing, spa type, and SCCmec showed that P1, P2 and P3 isolates were mainly clonal, whereas P4 isolates were more diverse. P1 comprised mainly ST247-I isolates, P2 mainly ST8-IVc, and P3 mainly ST8-IVc and ST5-VI. In conclusion, the epidemiology of MRSA in Paris is changing rapidly at the local level, with phenotypically defined clones being substituted by others, with associations existing between changes in specific patient populations or circumstances.

Vancomycin-resistant enterococci (VRE) are emerging in French hospitals. A VRE outbreak occurred in our hospital, prompting efforts to eradicate the organism. The following interventions were implemented simultaneously to control the outbreak: (1) creation of a VRE control committee; (2) cohorting of VRE carriers in a dedicated ward; (3) extensive screening of contact patients; (4) use of a sensitive technique for detecting VRE in rectal samples; (5) intervention of a dedicated team to reduce consumption of selected antibiotics; (6) information for, and education of, all hospital staff; and (7) electronic tracking of in-hospital transfer and readmission of VRE carriers and contact patients. Over a four-week period following admission of the index case, 37 carriers of a single strain of vanA vancomycin-resistant Enterococcus faecium were identified across seven units. A single additional readmitted contact patient was identified later. Of the 39 VRE-positive patients, two had urinary tract infections and 37 were colonised. Of the 32 patients with known VRE stool concentrations, 23 had low and nine high concentrations. One low-concentration patient precipitated transmission in another unit. This aggressive, co-ordinated, multifaceted strategy was successful in halting a widespread VRE outbreak in our hospital.

OBJECTIVES: To evaluate safety-engineered devices (SEDs) with respect to their effectiveness in preventing needlestick injuries (NSIs) in healthcare settings and their importance among other preventive measures. DESIGN: Multicenter prospective survey with a 1-year follow-up period during which all incident NSIs and their circumstances were reported. Data were prospectively collected during a 12-month period from April 1999 through March 2000. The procedures for which the risk of NSI was high were also reported 1 week per quarter to estimate procedure-specific NSI rates. Device types were documented. Because SEDs were not in use when a similar survey was conducted in 1990, their impact was also evaluated by comparing findings from the recent and previous surveys. SETTING: A total of 102 medical units from 32 hospitals in France. PARTICIPANTS: A total of 1,506 nurses in medical or intensive care units. RESULTS: A total of 110 NSIs occurring during at-risk procedures performed by nurses were documented. According to data from the 2000 survey, use of SEDs during phlebotomy procedures was associated with a 74% lower risk (P<.01). The mean NSI rate for all relevant nursing procedures was estimated to be 4.72 cases per 100,000 procedures, for a 75% decrease since 1990 (P<.01); however, the decrease in NSI rates varied considerably according to procedure type. Between 1990 and 2000, decreases in the NSI rates for each procedure were strongly correlated with increases in the frequency of SED use (r=0.88; P<.02). CONCLUSION: In this French hospital network, the use of SEDs was associated with a significantly lower NSI rate and was probably the most important preventive factor.

Injection pens are used by patients when auto-administering medication (insulin, interferon, apokinon etc.) by the subcutaneous route. The objective of this study was to evaluate the rate of injection pen use by healthcare workers (HCWs) and the associated risk of needlestick injuries to document and compare injury rates between injection pens and subcutaneous syringes. A one-year retrospective study was conducted in 24 sentinel French public hospitals. All needlestick injuries linked to subcutaneous injection procedures, which were voluntarily reported to occupational medicine departments by HCWs between October 1999 and September 2000, were documented using a standardized questionnaire. Additional data (total number of needlestick injuries reported, number of subcutaneous injection devices purchased) were collected over the same period. A total of 144 needlestick injuries associated with subcutaneous injection were reported. The needlestick injury rate for injection pens was six times the rate for disposable syringes. Needlestick injuries with injection pens accounted for 39% of needlestick injuries linked with subcutaneous injection. In all, 60% of needlestick injuries with injection pens were related to disassembly. Injection pens are associated with needlestick injuries six times more often than syringes. Nevertheless, injection pens have been shown to improve the quality of treatment for patients and may improve treatment observance. This study points to the need for safety-engineered injection pens.
