Performance of surgical site infection risk prediction models in colorectal surgery: external validity assessment from three European national surveillance networks.

Objective: To assess the validity of multivariable models for predicting risk of surgical site infection (SSI) after colorectal surgery based on routinely collected data in national surveillance networks.

Design: Retrospective analysis performed on 3 validation cohorts.

Patients: Colorectal surgery patients in Switzerland, France, and England, 2007-2017.

Influence of bacterial resistance on mortality in intensive care units: a registry study from 2000 to 2013 (IICU Study).

Background: Bacterial resistance to antibiotics is a daily concern in intensive care units. However, few data are available concerning the clinical consequences of in-vitro-defined resistance.

Aim: To compare the mortality of patients with nosocomial infections according to bacterial resistance profiles.

Impact of participation in a surgical site infection surveillance network: results from a large international cohort study.

Background: Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale.

Aim: To determine the time-trend of SSI rates in surveillance networks.

Methods: SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure.

Surgical site infection after trans urethral resection of the prostate (TURP): 2008-2013 French national SSI surveillance ISO-RAISIN.

Objective: To describe surgical site infection (SSI) after transurethral resection of prostate (TURP) from the French national database.

Methods: A national SSI surveillance system was implemented in 1999. Each year, the network included urology departments that included at least two months plus one month follow-up, or at least 100 consecutive targeted surgical procedures.

ICU-acquired candidaemia in France: Epidemiology and temporal trends, 2004-2013 - A study from the REA-RAISIN network.

Objective: Candidaemia is a life-threatening infectious disease, associated with septic shock, multiple organ failure, and a high mortality rate. In France, reported data on the incidence of ICU-acquired candidaemia and the causative Candida species are scarce. The objective of this study was to determine temporal trends in epidemiology and risk factors of intensive care unit-acquired candidaemia (ICU-Cand) and ICU mortality among a very large population of ICU patients.

Hand rub dose needed for a single disinfection varies according to product: a bias in benchmarking using indirect hand hygiene indicator.

Background: The 3ml volume currently used as the hand hygiene (HH) measure has been explored as the pertinent dose for an indirect indicator of HH compliance. A multicenter study was conducted in order to ascertain the required dose using different products.

Method: The average contact duration before drying was measured and compared with references.

Bacterial and fungal counts in hospital air: comparative yields for 4 sieve impactor air samplers with 2 culture media.

We compared the yields of 4 recently developed sieve impactor air samplers that meet international standard ISO 14698-1, using 2 growth media (tryptic soy agar and malt extract agar) in real conditions of use. Several hospital sites expected to have different densities of airborne microflora were selected in 2 hospitals. The Samplair MK2, Air Ideal, and Mas-100 samplers yielded higher bacterial counts than did the SAS Super-100 device (P<.

Comparison of epidemiological, clinical, and biological features of invasive aspergillosis in neutropenic and nonneutropenic patients: a 6-year survey.

Background: Invasive aspergillosis is an opportunistic infection that occurs mainly among patients with prolonged neutropenia. Few data are available on invasive aspergillosis in nonneutropenic patients.

Methods: The aim of this survey was to compare neutropenic and nonneutropenic patients who had received a diagnosis of invasive aspergillosis at our institution during a 6-year period.

[Bacteriological control of food for immunocompromised host].

This study concerning bacteriological controls of food for immuno-suppressive patients have shown that food sterilized in sterilizer or with pressure-cooker contains sporulated bacteria after treatment. Unit packaging or freeze-drying commercial foods offer no bacteriological quality guarantees. Clinicians have to define acceptable contamination rate according to their patients' condition.
