Measures of User experience in a Streptococcal pharyngitis and Pneumonia Clinical Decision Support Tools

Objective: To understand clinician adoption of CDS tools as this may provide important insights for the implementation and dissemination of future CDS tools. Materials and Methods: Clinicians (n=168) at a large academic center were randomized into intervention and control arms to assess the impact of strep and pneumonia CDS tools. Intervention arm data were analyzed to examine provider adoption and clinical workflow. Electronic health record data were collected on trigger location, the use of each component and whether an antibiotic, other medication or test was ordered. Frequencies were tabulated and regression analyses were used to determine the association of tool component use and physician orders. Results: The CDS tool was triggered 586 times over the study period. Diagnosis was the most frequent workflow trigger of the CDS tool (57%) as compared to chief complaint (30%) and diagnosis/antibiotic combinations (13%). Conversely, chief complaint was associated with the highest rate (83%) of triggers leading to an initiation of the CDS tool (opening the risk prediction calculator). Similar patterns were noted for initiation of the CDS bundled ordered set and completion of the entire CDS tool pathway. Completion of risk prediction and bundled order set components were associated with lower rates of antibiotic prescribing (OR 0.5; CI 0.2-1.2 and OR 0.5; CI 0.3-0.9, respectively). Discussion: Different CDS trigger points in the clinician user workflow lead to substantial variation in downstream use of the CDS tool components. These variations were important as they were associated with significant differences in antibiotic ordering. Conclusions: These results highlight the importance of workflow integration and flexibility for CDS success

Microbiological and molecular characteristics of carbapenemase-producing klebsiella pneumoniae endemic in a tertiary Greek hospital during 2004-2010

We report 570 carbapenemase-producing Klebsiella pneumoniae (CPKP) clinical isolates in a 1,040-bed Greek tertiary hospital during 2004 to 2010. The first CPKP (VIM-producing) was isolated in September 2004. Despite initial containment, VIM producers have become endemic since 2006. KPC-producing K. pneumoniae was first isolated in August 2007 from a patient who came from Israel, spread rapidly, and outcompeted VIM. Overall, 267 (47%) VIM-producing and 301 (53%) KPC-producing strains were isolated, including 141 (24.7%) from patients with bacteraemia. Two isolates carrying both VIM and KPC were isolated in two consecutive months in 2009, but not since. The prevalence of CPKP increased from 0% in 2003 to 38.3% in 2010 (

Nutrient intake during pregnancy and adherence to dietary recommendations: The mediterranean phime cohort

Few studies provide a detailed description of dietary habits during pregnancy, despite the central role of nutrition for the health of the mother and offspring. This paper describes the dietary habits, energy and nutrient intake in pregnant women from four countries belonging to the Mediterranean PHIME cohort (Croatia, Greece, Italy and Slovenia) and evaluates their adherence to the European Food Safety Authority (EFSA) recommendations. A total of 1436 women were included in the present analysis. Maternal diet was assessed using a food frequency questionnaire (FFQ). The mean macro and micronutrient intakes were estimated and compared with the dietary reference values (DRVs). The percentage distribution of the 16 food groups in the total intake of each macronutrient was estimated. All women shared a similar diet during pregnancy; almost all the women in the four countries exceeded the DRV for sugars, and the total fat intake was above the DRV in most women in all the countries, as was the contribution of saturated fatty acids (SFAs) to the total energy intake. In all four countries, we observed an increased risk of micronutrient deficiency for iron, folate and vitamin D. Shared guidelines, implemented at both the national and European level, are essential to improve the maternal nutritional status during pregnancy

Substantially increased faecal carriage of vancomycin-resistant enterococci in a tertiary Greek hospital after a 4 year time interval

Objectives: In a tertiary Greek hospital with no documented vancomycin-resistant enterococci (VRE) infections, a cross-sectional study was conducted in order to determine the degree of VRE faecal carriage among adult patients hospitalized in high-risk units. Methods: Specimens for the surveillance were collected from separate patients in two periods (January-May 1999 and January-May 2003); 258 specimens were submitted during the first period and 149 during the second period. Results: Three patients (1.2%) were colonized with VRE during the first period, whereas 52 (34.9%) were colonized during the second period. Two VRE isolates of the first period were Enterococcus faecalis and one Enterococcus faecium, whereas those of the second period were E. faecium except for three E. faecalis and two Enterococcus gallinarum. All VRE isolates apart from the two E. gallinarum isolates were positive for the vanA gene. The 48 vancomycin-resistant E. faecium were classified into eight clonal types, one of those predominating with 29 isolates; the remaining included one to nine isolates. The five vancomycin-resistant E. faecalis formed four distinct clonal types. Conclusions: The study reports a substantially higher prevalence of VRE carriage when the surveillance was repeated after a 4 year time interval. Urgent infection control measures are needed to prevent emergence of VRE outbreaks in our hospital setting. © The British Society for Antimicrobial Chemotherapy 2004; all rights reserved

CTX-M-1 extended-spectrum β-lactamase-producing Proteus mirabilis in Greece

To examine the dissemination of CTX-M-type extended-spectrum β-lactamases (ESBLs) in clinical isolates of Proteus mirabilis, 91 nonrepetitive ESBL-producing P. mirabilis were collected from infected patients in a tertiary Greek hospital during September, 2001, to May, 2004. A bla CTX-M gene was amplified in one isolate (strain A328), but bla CTX-M was not detected in any of the remaining ESBL producers. Sequencing results showed that P. mirabilis A328 produced a CTX-M-1 enzyme while PCR mapping of the genetic element carrying blaCTX-M-1 revealed that the gene was located downstream of an ISEcp1B element. The cefotaxime resistance determinant was easily transferable and carried on a 70-kb plasmid. The emergence of CTX-M-1-producing P. mirabilis indicates the need for early recognition of such strains to be able to control their spread in our hospital and community environment. © Mary Ann Liebert, Inc

A fatal case of Ludwig's angina and mediastinitis caused by an unusual microorganism, Gemella morbillorum

We present a case of Ludwig's angina in a 48-y-old immunocompetent male caused by an unusual pathogen, Gemella morbillorum. The infection was complicated with mediastinitis and despite aggressive management of the disease the patient died after 12 d of hospitalization. This is the first reported case of Ludwig's angina caused by G. morbillorum and emphasizes that the disease remains a potentially lethal infection. © 2005 Taylor & Francis
