    Objective: To evaluate whether public reporting of performance data was associated with a change over time in quality indicators for acute myocardial infarction (AMI) in Italian hospitals. Design: Pre-post evaluation of AMI indicators in the Lazio region, before and after disclosure of the Regional Outcome Evaluation Program, and a comparative evaluation versus other Italian regions not participating in the program. Setting/data sources: Nationwide Hospital Information System and vital status records. Participants: 24 800 patients treated for AMI in Lazio and 39 350 in the other regions. Intervention: Public reporting of the Regional Outcome Evaluation Program in the Lazio region. Main Outcome Measure: Risk-adjusted indicators for AMI. Results: The proportion of ST-segment elevation myocardial infarction (STEMI) patients treated with percutaneous coronary interventions (PCI) within 48 h in Lazio changed from 31.3 to 48.7%, before and after public reporting, respectively (relative increase 56%; P < 0.001). In the other regions, the proportion increased from 51.5 to 58.4% (relative increase 13%; P < 0.001). Overall 30-day mortality and 30-day mortality for patients treated with PCI did not improve during the study period. The 30-day mortality for STEMI patients not treated with PCI in Lazio was significantly higher in 2009 (29.0%) versus 2006/07 (24.0%) (P =.002). Conclusions: Public reporting may have contributed to increasing the proportion of STEMI patients treated with timely PCI. The mortality outcomes should be interpreted with caution. Changes in AMI diagnostic and coding systems should also be considered. Risk-adjusted quality indicators represent a fundamental instrument for monitoring and potentially enhancing quality of care. © The Author 2014.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Variations on the Author

    “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

    We 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

    Characteristics and effectiveness of smoking cessation programs in Italy. Results of a multicentric longitudinal study

    AIM: to describe the characteristics and effectiveness of various smoking cessation programs offered by Italian treatment services operating within the National Health Service. DESIGN: prospective longitudinal multicentre study involving 41 smoking cessation services in 16 Italian regions. Study population: the study population includes patients entering smoking cessation programs between April 2003 and June 2004. The "study population" includes 1226 patients (54.2% males and 45.4% females), mean age 47 years. Patients have a middle/high level of education and a long history of smoking; most are highly dependent on nicotine and report previous attempts to quit smoking. METHODS: treatment effectiveness in smoking cessation is assessed six months after entering treatment service. Logistic Regression Model was used to determine the predictors of successfiul cessation, independent of treatment typology. The predictors were included as confounding variables in the logistic regression model that was used to evaluate the effectiveness of treatments. Besides the effect of treatment completion on smoking cessation was estimated. RESULTS: predictors of successful smoking cessation are: being male, presence of a partner, strong motivation to quit, previous attempts to give up smoking, mild nicotine dependence, and not suffering from mood disturbances. All treatments are effective in helping people to stop smoking: cessation rate ranges between 25.00% for patients receiving a single session of motivational counselling and 65.3% for those receiving nicotine replacement therapy combined to group therapy. Compared to a single session of motivational counseling, nicotine replacement therapy combined to group therapy is the most effective therapeutic program (OR 5.4; 95%CI 12.5-12.0). Treatment completion is a strong determinant ofsuccess (OR 4.8; 95%CI 3.5-6.4). CONCLUSION: enrolling people in any type of therapeutic program, in particular nicotine replacement therapy combined with group therapy increases the probability of successfully quitting smoking; moreover, patients that begin a smoking cessation program should be encouraged to complete the therap

    Dispelling the Myths Behind First-author Citation Counts

    We 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 text
    We 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
