Peer support by health care providers in aftermath of patient safety incidents: a cross-sectional study
Full text linkAIM: To investigate the health care professionals' preferences pertaining to support in the aftermath of patient safety incidents and potential variation thereof depending on the degree of harm. BACKGROUND: Peer support systems are available to support health care professionals in the aftermath of patient safety incidents. It is unclear which type of support is best offered by whom. METHODS: A cross-sectional study in 32 Dutch hospitals. RESULTS: In total, 2,362 nurses and 1,404 doctors indicated they were involved in patient safety incidents at any time during their career (86%). Less than 10% of health care providers had spoken with professional support, and less than 20% admitted a need to do so. They used different support. A higher degree of harm related to higher odds of desiring support. Respondents mainly wanted to understand what happened and how it can be prevented. CONCLUSION: The desired support of health care professionals in the aftermath of patient safety incidents depends on the level of harm. IMPLICATION FOR NURSING MANAGEMENT: Health care professionals seem to mostly rely on persons they are close with, and they mainly desire information related to the aftermath of patient safety incidents. This should be taken into account when support programmes are set up.sponsorship: This study was carried out with an unconditional grant from VvAA (VvAA)status: Published onlin
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Magnetic resonance imaging and cerebrovascular hemodynamics in (pre)-eclampsia
Full text linkHoge bloeddruk tijdens de zwangerschap is gevaarlijk. De mogelijke gevolgen, zoals hersenoedeem, stuipen en hersenbloedingen, eisen jaarlijks wereldwijd 50 tot 65 duizend vrouwenlevens. Ook in Nederland is deze zogeheten 'preëclampsie' de hoofdoorzaak van moedersterfte. Toch grijpen artsen vaak te laat in volgens Gerda Zeeman. Dit omdat er te weinig bekend is in de medische wetenschap over veranderingen in de hersendoorbloeding. Ook leren de handboeken dat vrouwen in principe geheel herstellen. Zeeman bracht als eerste de veranderingen in de hersenen in beeld en constateert onder meer dat er wel degelijk blijvende schade kan zijn.
Hoge bloeddruk komt ongeveer bij vijf tot tien procent van de zwangerschappen voor. Bij een patiënt met preëclampsie (ook wel zwangerschapsvergiftiging of toxicose genoemd) kunnen stuipen ontstaan, soms gevolgd door een hersenbloeding. Dit komt omdat de bloeddruk dan acuut stijgt. Zeeman heeft tijdens haar opleiding veel ervaring opgedaan met de behandeling van deze patiënten: ‘Een stuipende vrouw zorgt voor een angstaanjagend moment voor artsen en verpleegkundigen en het is een drama wanneer je een moeder daarna ziet overlijden.’ Medische handboeken onderwijzen dat een vrouw geheel herstelt na stuipen en dat hersenbloedingen zeldzaam zijn. Daarom wordt er momenteel vaak veel te laat gestart met bloeddrukverlagende medicatie. Maar een groot deel van de vrouwen lijkt jarenlang verschijnselen over te houden aan de stuipen, zoals geheugenverlies en gebrek aan concentratievermogen.
Blijvende schade
Het is bekend dat zwangerschap voor grote veranderingen zorgt in de belasting van hart en bloedvaten, maar de veranderingen in de doorbloeding van de hersenen zijn tot nu toe nagenoeg niet onderzocht. Daarom zijn artsen onzeker welke preventie of behandeling toe te passen. Met moderne MRI-technieken bracht Zeeman in beeld dat bij gezonde zwangere vrouwen de bloeddoorstroming in de hersenen afneemt, terwijl er juist een toename is bij vrouwen met zwangerschapshypertensie. Waarschijnlijk leidt dit mechanisme uiteindelijk tot stuipen. Verder ontdekte de promovendus dat een kwart van de patiënten in meer of mindere mate blijvende hersenschade overhoudt aan stuipen.
Stuipen en hersenbloedingen zijn in veel gevallen te voorkomen door tijdig de bloeddruk te verlagen en magnesiumsulfaat toe te dienen. Dat gebeurt helaas nog veel te weinig in Nederland. Hoe het magnesiumsulfaat werkt is niet bekend. Men denkt dat het samentrekking van de hersenvaten tegengaat, maar Zeeman ontdekte dat het gunstige effect van magnesiumsulfaat daar niet aan toe te schrijven is.
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
