PTH-32 development of a novel electronic referral grading & triage system
No full textIntroduction: prior to Covid-19, demand for secondary care appointments continued to rise year on year suggesting unsustainable future post-pandemic demand. Now is thus the right time to invest in triage and clinical pathway innovation.Methods: anew fully-integrated digital triage system was built at our institution allowing for document upload and electronic triage. Data pertaining to referral time, triage decision, outpatient appointments and direct-to-test was extracted from the backend to plot empirical cumulative distribution functions, interquartile ranges and allow statistical comparison using the Kruskal-Wallis’ test.Results: we analysed the first 704 luminal Gastroenterology referrals through the new triage system with the following sub-specialty classifications: Iron deficiency anaemia (IDA) – 200, Upper gastrointestinal symptoms (UGI) – 152, Inflammatory bowel disease (IBD) – 116, Irritable bowel syndrome (IBS/Functional) – 95, Lower gastrointestinal symptoms/change in bowel habit alone (LGI/CIBH) – 59, Coeliac – 27, Surgical – 25, Complex Functional – 12, Intestinal failure (IF/Nutrition) – 12, Hepatology – 4. 664 (95%) of referrals were accepted with 179 (27%) being sent direct to test. Of these only 42 (23.5%) had a subsequent clinic appointment booked, vs 436 (90%) for those not going direct to test. In addition, sending patients direct to test increased the proportion of subsequent routine clinic appointments from 55% to 70%. Median timelag from referral to grading was four days with grading taking a single day and appointments occurring 17 days later on average. Direct-to-test was most common amongst patients in the UGI (52.6%) and IBD (50%) sub-cohorts. This was significantly different vs other groups at the (p<0.05) level. [PTH-32 Figure 1 Subspecialty Referrals vs Direct-To-Test Numbers not included].Conclusions: using a system as described here substantially improves data capture and efficiency. Direct to test reduces both need for clinic appointments and the urgency of subsequent appointments. IBD and UGI are the subspecialties most likely to benefit from direct to test approaches. IDA could be another suitable specialty and the plan is to address this in the future
PTH-36 identification & service evaluation of a primary sclerosing cholangitis cohort using natural language processing
No full textIntroduction: primary sclerosing cholangitis (PSC) is a rare and difficult to treat condition. PSC is strongly associated with malignancy, therefore screening and surveillance are paramount. PSC however does not have a unique UK ICD-10 diagnostic code, hence reliable patient cohort identification and thorough service evaluation is challenging. We used natural language processing (NLP) to identify the PSC patient cohort at University Hospital Southampton (UHS) and audited associated outcomes against recently updated British Society of Gastroenterology (BSG) management guidelines.Method: records of all patients with PSC at our institution between 2008-2020 were identified using our NLP methodology. We used fuzzy matching to analyse clinical records, and tokenized and lemmatized key paragraphs to identify key diagnostic patterns and exclude diagnostically uncertain or exclusive sentences. Anonymised discharge summaries, clinic letters, radiology reports, endoscopy records and histology were extracted and digitally trawled to identify the cohort characteristics.Results: we identified 125 patients with PSC followed-up at UHS. 39.2% (49) of these patients were missed in a parallel criterion-based review of case notes.We calculated an age-standardised point prevalence of 12.52 cases per 100,000 patients, 124% higher than typically cited UK figures. Service evaluation revealed high rates of clinic follow-up however lower than recommended rates of screening with colonoscopy and imaging (see Table 1). Introduction of a combined PSC/IBD clinic as a targeted service delivery intervention is addressing this shortfall with significant impact after 1 year. [PTH-36 Table 1 not included].Conclusions: PSC cohorts are difficult to identify due to a lack of a UK clinical code. An NLP based methodology proved highly effective at identifying all cases within our institution, with a 64.5% increase compared to conventional methods. This allowed rapid patient cohort identification and conversion of unstructured data to clinically useful structured data and could be reproduced at other institutions and for other diseases
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
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
