Cost comparison of four venous catheters: Short peripheral catheter, Long peripheral line, Midline, and PICC for peripheral infusion.

INTRODUCTION: The use of midline catheters for patients requiring a peripheral IV infusion is sometimes limited by their cost. Although decision trees allow them to be positioned in relation to short peripheral cannulas (SPC), Midlines, and PICCs, their economic impact has not yet been evaluated. A study was conducted to estimate and compare the actual costs of using the three types of catheters for durations of 7, 14, and 21 days. METHODS: A budget impact analysis compared midlines or mini-midlines/long peripheral cannulas (LPCs) with SPCs and PICCs for typical medical indications excluding indications requiring central line (infusion of irritant or vesicant drugs): treatment of peritonitis over 7 days, cystic fibrosis infection over 14 days, and meningitis over 21 days. A micro-costing study identified resources used during catheter care procedures (consumables, medical/nursing care, examinations, mechanical complications). The cost of remote systemic complications was estimated from the French national cost study. Literature review compared data based on published complication frequencies. RESULTS: Midline is more economic than the SPC (saving of 39€ over 7 days and 174€ over 14 days), and than the PICC (saving of 102€ over 14 days and 95€ over 21 days). DISCUSSION: Despite a much higher acquisition cost of the Midline than a SPC, the cost of using a Midline is lower. Although this approach cannot be the only argument for choosing a medical device, it can contribute to it in a tense economic context. The micro-costing has been performed in a center placing PICCline using fluoroscopy for catheter tip positioning. The implantation of a PICC with ECG technique does not require an interventional radiology facility and involves significantly lower logistical and personnel costs. This factor is a limitation in this study. However, even with the use of EGC, the cost difference is in favor of Midline.

Identifying individual and organizational predictors of accidental exposure to blood (AEB) among hospital healthcare workers: A longitudinal study.

BACKGROUND: Accidental exposure to blood (AEB) poses a risk of bloodborne infections for healthcare workers (HCWs) during hospital activities. In this study, we identified individual behavioral and organizational predictors of AEB among HCWs. METHODS: The study was a prospective, 1-year follow-up cohort study conducted in university hospitals in Paris, France. Data were collected from the Stress at Work and Infectious Risk in Patients and Caregivers (STRIPPS) study. Eligible participants included nurses, nursing assistants, midwives, and physicians from 32 randomly selected wards in 4 hospitals. AEB occurrences were reported at baseline, 4 months, 8 months, and 12 months, and descriptive statistical and multilevel risk-factor analyses were performed. RESULTS: The study included 730 HCWs from 32 wards, predominantly nurses (52.6%), nursing assistants (41.1%), physicians (4.8%), and midwives (1.5%). The incidence rate of AEB remained stable across the 4 visits. The multilevel longitudinal analysis identified several significant predictors of AEB occurrence. Individual-level predictors included younger age, occupation as nurses or midwives, irregular work schedule, rotating shifts, and lack of support from supervisors. The use of external nurses was the most significant ward-level predictor associated with AEB occurrence. CONCLUSIONS: AEBs among HCWs are strongly associated with organizational predictors, highlighting the importance of complementing infection control policies with improved staff management and targeted training. This approach can help reduce AEB occurrences and enhance workplace safety for HCWs.

Multilevel approach to individual and organisational predictors of stress and fatigue among healthcare workers of a university hospital: a longitudinal study.

OBJECTIVE: Healthcare workers (HCWs) are at high risk of experiencing stress and fatigue due to the demands of their work within hospitals. Improving their physical and mental health and, in turn, the quality and safety of care requires considering factors at both individual and organisational/ward levels. Using a multicentre prospective cohort, this study aims to identify the individual and organisational predictors of stress and fatigue of HCWs in several wards from university hospitals. METHODS: Our cohort consists of 695 HCWs from 32 hospital wards drawn at random within four volunteer hospital centres in Paris-area. Three-level longitudinal analyses, accounting for repeated measures (level 1) across participants (level 2) nested within wards (level 3) and adjusted for relevant fixed and time-varying confounders, were performed. RESULTS: At baseline, the sample was composed by 384 registered nurses, 300 auxiliary nurses and 11 midwives. According to the three-level longitudinal models, some predictors were found in common for both stress and fatigue (low social support from supervisors, work overcommitment, sickness presenteeism and number of beds per ward). However, specific predictors for high level of stress (negative life events, low social support from colleagues and breaks frequently cancelled due to work overload) and fatigue (longer commuting duration, frequent use of interim staff in the ward) were also found. CONCLUSION: Our results may help identify at-risk HCWs and wards, where interventions to reduce stress and fatigue should be focused. These interventions could include manager training to favour better staff support and overall safety culture of HCWs.

Non-Legionella pneumophila serogroup 1 pneumonia: Diagnosis of a nosocomial legionellosis with the Biofire Pneumonia plus panel.

We report a nosocomial case of Legionella pneumophila pneumonia caused by a serogroup 10 strain diagnosed with the Biofire® Pneumonia plus panel. Molecular investigations of the environment of the patient allowed us to identify the source of contamination.

Two per cent alcoholic chlorhexidine versus alcoholic five per cent povidone-iodine for the prevention of perineural catheter colonisation: The CHLOVEPI randomised, controlled trial.

BACKGROUND: Multimodal analgesia, including a regional technique using perineural catheters (PNCs), is recommended for the treatment of moderate-to-severe acute postoperative pain. Perineural catheters are at risk of bacterial colonisation. In this study, we compared the cutaneous antiseptic efficacy of 2% alcoholic chlorhexidine and povidone-iodine-alcohol for preventing the bacterial colonisation of PNCs in orthopaedic surgery. METHODS: We performed a randomised, controlled trial, comparing two cutaneous antisepsis strategies, one based on 2% alcoholic chlorhexidine and the other on povidone-iodine-5% alcohol, for placed PNCs before orthopaedic surgery. The primary endpoint was the incidence of catheter bacterial colonisation (threshold > 1000 colony-forming units/ml). The secondary endpoints were the incidence of catheter-related infections and the adverse effects of the antiseptic solutions. RESULTS: From November 2016 to May 2018, we included 113 patients in this study. The use of alcoholic chlorhexidine was associated with a lower incidence of catheter colonisation (15.5% (n = 9) versus 32.7% (n = 18); OR: 0.28 [0.09-0.77], p = 0.01). No catheter-related infections or adverse effects of antiseptic solutions were observed in either group. The risk factors associated with colonisation were a duration of catheter use ≥ 3 days (p = 0.04) and obesity (p = 0.005). The most frequently identified bacterium was Staphylococcus epidermidis. CONCLUSION: Skin disinfection with 2% alcoholic chlorhexidine decreases bacterial colonisation rates for placed perineural catheters.

[Relevance of a catheter team for short stays with elderly people]. / Pertinence d'une équipe cathéters en court séjour auprès des personnes âgées.

Elderly patients hospitalized in acute care service very often have a weakened venous tissue which, in the case of medium-term intravenous treatment, leads to multiple painful punctures. In order to alleviate this major inconvenience, within the framework of a cooperation protocol, a catheter team was trained in the ultrasound-guided insertion of the appropriate catheter for the management of geriatric patients.

Germs of thrones - spontaneous decolonization of Carbapenem-Resistant Enterobacteriaceae (CRE) and Vancomycin-Resistant Enterococci (VRE) in Western Europe: is this myth or reality?

Background: In France, Carbapenem-Resistant Enterobacteriaceae (CRE) and Vancomycin-Resistant Enterococci (VRE) are considered as Extensively Drug-Resistant (XDR) bacteria. Their management requires reinforcement of hospital's hygiene policies, and currently there is few consistent data concerning the spontaneous decolonization in XDR colonized patients. Our aim is to study the natural history of decolonization of XDR carriers over time in a hospital setting in a low prevalence country. Material and methods: Retrospective multicenter study over 2 years (2015-2016) in 2 different tertiary care hospital sites and units having an agreement for permanent cohorting of such XDR carriers. We gathered the type of microorganisms, risk factors for colonization and rectal swabs from patient's follow-up. We also evaluated patient care considering isolation precautions. Results: We included 125 patients, aged 63+/-19y, including 72.8% of CRE (n = 91), 24.8% of VRE (n = 31) and 2.4% (n = 3) co-colonized with CRE and VRE. CRE were mainly E. coli (n = 54), K. pneumoniae (n = 51) and E. cloacae (n = 6). Mechanisms of resistance were mainly OXA-48 (n = 69), NDM-1 (n = 11), OXA-232 (n = 8) and KPC (n = 3).Prior antibiotic therapy was reported in 38.4% (n = 48) of cases. Conversely, 17.6% (n = 22) received antibiotics during follow-up.Spontaneous decolonization occurred within the first 30 days in 16.4% (n = 19/116) of cases and up to 48.2% after day-90 with a median follow-up of 96 days (0-974).We estimated that XDR carriage was associated with a larger care burden in 13.6% (n = 17) of cases, especially due to a prolongation of hospitalization of 32.5 days (15-300). Conclusions: Our study shows that spontaneous decolonization is increasing over time (up to 48.2%). We can regret that only few patients underwent screening after 1 year, emphasizing the need for more monitoring and prospective studies.

Epidemiology of extended-spectrum beta-lactamase-producing Enterobacteriaceae in an intensive care unit with no single rooms.

BACKGROUND: The transmission of extended-spectrum beta-lactamase-producing enterobacteriaceae (ESBL) is prevented by additional contact precautions, mainly relying on isolation in a single room and hand hygiene. Contact isolation cannot be achieved in our 12-bed ICU, which has only double rooms. We report the epidemiology of ESBL imported, acquired and transmitted in an ICU with no single rooms. METHODS: We prospectively conducted an observational and non-interventional study in a French 12-bed ICU. Inclusion criteria were patients >18 years of age treated by at least two successive nursing teams. Patient characteristics at admission and clinical data during hospital stay were collected prospectively. ESBL carriage was monitored using rectal swabs collected at admission and once weekly during the ICU stay. Potential cross-transmission was studied (1) by identifying index patients defined as possible ESBL sources for transmission, (2) by classifying each ESBL strain according to the cefotaximase München (CTXM) 1 and 9 groups and (3) by gene sequencing for remaining cases of possible transmission. RESULTS: From June 2014 to April 2015, of 550 patients admitted to the ICU, 470 met the inclusion criteria and 221 had at least two rectal swabs. The rate of ESBL colonization, mainly by Escherichia coli, at admission was 13.2%. The incidence of ESBL acquisition, mainly with E. coli too, was 4.1%. Mortality did not differ between ESBL carriers and non-carriers. In univariate analysis, ESBL acquisition was associated with male gender, SAPS II, SOFA, chronic kidney disease at admission, duration of mechanical ventilation, need for catecholamine and the ICU LOS. In multivariate analysis, SAPS II at admission was the only risk factor for ESBL acquisition. We confirmed cross-transmission, emanating from the same index patient, in two of the nine patients with ESBL acquisition (0.8%, 2/221). No case of cross-transmission in the same double room was observed. DISCUSSION AND CONCLUSION: Prevalence of ESBL colonization in our ICU was 13.2%. Despite the absence single rooms, the incidence of ESBL acquisition was 4.1% and cross-transmission was proven in only two cases, resulting from the same index patient who was not hospitalized in the same double room.

Clinical features of Clostridium difficile-associated diarrhoea due to binary toxin (actin-specific ADP-ribosyltransferase)-producing strains.

Toxins A and B are known to be the primary virulence factors of Clostridium difficile. Other potential virulence factors have been identified such as binary toxin (actin-specific ADP-ribosyltransferase toxin, or CDT). A retrospective case-control study was performed in order to identify clinical features and risk factors of C. difficile-associated diarrhoea due to binary toxin-producing strains. Each case (a patient with diarrhoea due to binary toxin-producing strain) was compared with two controls (patients with diarrhoea due to a C. difficile strain that did not produce binary toxin) matched for ward and date of hospitalization. cdtA and cdtB genes were screened by PCR. Production of CDT was studied by Western blotting using an antiserum against Ia and Ib from the Clostridium perfringens iota toxin, and the activity of the binary toxin was assessed using an ADP-ribosyltransferase assay. Twenty-six cases (14 males and 12 females) were identified in 1999 and 2000. Cases and controls did not differ significantly for sex, age, previous administration of antibiotics or frequency of endoscopic examination. Diarrhoea was community-acquired more often in cases than in controls (65.4 vs 35.7 %, P = 0.017) and more often represented the cause of hospitalization (61.5 vs 26.2 %, P = 0.003). Moreover, diarrhoea in cases was more frequently associated with abdominal pain (63.6 vs 39.4 %, P = 0.07) and with liquid stools (76.9 vs 59.5 %, P = 0.14) than in controls. These results suggest that there could be a correlation between the production of binary toxin and the severity of diarrhoea.

Emergence and spread of three clonally related virulent isolates of CTX-M-15-producing Escherichia coli with variable resistance to aminoglycosides and tetracycline in a French geriatric hospital.

Three types of multidrug-resistant Escherichia coli isolates, called GEN S, GEN R, and AMG S, according to their three different aminoglycoside resistance patterns, were responsible for urinary tract colonization or infection in 87, 12, and 13 new patients, respectively, in a French 650-bed geriatric hospital over a 13-month period. The three E. coli types belonged to the same clone and phylogenetic group (group B2) and had identical transferable plasmid contents (a 120-kb plasmid), beta-lactam and fluoroquinolone resistance genotypes (bla(TEM-1B), bla(CTX-M-15), and double mutations in both the gyrA and the parC genes), and virulence factor genotypes (aer, fyuA, and irp2). They disseminated in the geriatric hospital, where the antibiotics prescribed most often were fluoroquinolones and ceftriaxone, but not in the affiliated acute-care hospital, where isolation precautions were applied to the transferred patients. Thus, E. coli isolates, both CTX-M-type beta-lactamase producers and fluoroquinolone-resistant isolates, might present a new challenge for French health care settings.
