No full textValidation of home oxygen saturations as a marker of clinical deterioration in patients with suspected COVID-19
No full textBackground The early identification of deterioration in suspected COVID-19 patients managed at home enables a more timely clinical intervention, which is likely to translate into improved outcomes. We undertook an analysis of COVID-19 patients conveyed by ambulance to hospital to investigate how oxygen saturation and measurements of other vital signs correlate to patient outcomes, to ascertain if clinical deterioration can be predicted with simple community physiological monitoring. Methods A retrospective analysis of routinely collected clinical data relating to patients conveyed to hospital by ambulance was undertaken. We used descriptive statistics and predictive analytics to investigate how vital signs, measured at home by ambulance staff from the South Central Ambulance Service, correlate to patient outcomes. Information on patient comorbidities was obtained by linking the recorded vital sign measurements to the patient's electronic health record at the Hampshire Hospitals NHS Foundation Trust. ROC analysis was performed using cross-validation to evaluate, in a retrospective fashion, the efficacy of different variables in predicting patient outcomes. Results We identified 1,080 adults with a COVID-19 diagnosis who were conveyed by ambulance to either Basingstoke & North Hampshire Hospital or the Royal Hampshire County Hospital (Winchester) between March 1st and July 31st and whose diagnosis was clinically confirmed at hospital discharge. Vital signs measured by ambulance staff at first point of contact in the community correlated with patient short-term mortality or ICU admission. Oxygen saturations were the most predictive of mortality or ICU admission (AUROC 0.772 (95 % CI: 0.712-0.833)), followed by the NEWS2 score (AUROC 0.715 (95 % CI: 0.670-0.760), patient age (AUROC 0.690 (95 % CI: 0.642-0.737)), and respiration rate (AUROC 0.662 (95 % CI: 0.599-0.729)). Combining age with the NEWS2 score (AUROC 0.771 (95 % CI: 0.718-0.824)) or the measured oxygen saturation (AUROC 0.820 (95 % CI: 0.785-0.854)) increased the predictive ability but did not reach significance. Conclusions Initial oxygen saturation measurements (on air) for confirmed COVID-19 patients conveyed by ambulance correlated with short-term (30-day) patient mortality or ICU admission, AUROC: 0.772 (95% CI: 0.712-0.833). We found that even small deflections in oxygen saturations of 1-2% below 96% confer an increased mortality risk in those with confirmed COVID at their initial community assessments
Introduction of a section for recording dementia improves data capture on the ambulance electronic patient record: evidence from a regional quality improvement project
No full textBackground: dementia is a common comorbidity in older people who require urgent or emergency ambulance attendance and influences clinical decisions and care pathways. Following an initial audit of dementia data and consultation with staff, a specific section (tab) to record dementia was introduced on an ambulance service electronic patient record (ePR). This includes a dementia diagnosis button and a free text section. We aimed to assess whether and how this improved recording. Aims: to re-audit the proportion of ambulance ePRs where dementia is recorded for patients aged ≥65 years and describe the frequency of recording in patients aged <65; to analyse discrepancies in the place of recording dementia on the ePR by comparing data from the new dementia tab and other sections of the ePR.Results: we included 112,193 ePRs of patients aged ≥65 with ambulance attendance from a 6 month period. The proportion with dementia recorded in patients aged ≥65 was 16.5%, increasing to 19.8% in patients aged ≥75, as compared to 13.5% (≥65) and 16.5% (≥75) in our previous audit. In this audit, of the 16.5% (n=18,515) of records with dementia, 69.9% (n=12,939) used the dementia button and 25.4% (n=4,704) recorded text in the dementia tab. Dementia was recorded in ePR free text fields (but not the dementia tab) in 29.7% of records. Eighteen other free text fields were used in addition to, or instead of, the dementia tab, including the patient’s social history, previous medical history and mental health. Dementia was present on the ePR of 0.4% (n=461) of patients aged <65.Conclusions: an ePR dementia tab enabled ambulance clinicians to standardise the location of recording dementia and may have facilitated increased recording. We would recommend other ambulance Trusts capture this information in a specific section to improve information sharing and inform care planning for this patient group. <br/
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
Improving recording and reporting of dementia and frailty via electronic patient record by ambulance staff in a single service (IDEAS)
No full textBackground: Dementia is common in older adults assessed by ambulance services. However, inconsistent reporting via the patient record may result in this diagnosis being overlooked by healthcare staff further down the care pathway. This can have a deleterious effect on subsequent patient care, increasing morbidity and mortality. We sought to understand how and where ambulance staff would like to record this finding on the electronic patient record (ePR).Methods: We designed and implemented a survey of ambulance staff in a single service to understand how they identify patients with dementia, how they record dementia on the ePR and how the ePR could be improved to better capture dementia. Scoping questions on frailty were included. The survey was tested using cognitive interviewing. Analysis was conducted using descriptive statistics for closed questions and thematic analysis for open questions as appropriate.Results: 131 surveys were completed; 60% of participants were paramedics and 40% were other grades of front line staff. Participants reported consulting electronic/paper sources, and individuals such as carers involved in the patients' care, to establish whether dementia had been diagnosed. Frailty assessments were prompted by social context, reduced mobility, a fall or diagnosis of dementia. Staff reported documenting dementia in 20 different areas on the ePR and 46% of participants stated a preference for a designated area to record the information. However, 15% indicated it was not necessary to record dementia or that no ePR changes were required.Conclusions: We have highlighted the variation in ambulance staff practice in recording of dementia. Alterations to the ePR are required to ensure that dementia is recorded consistently and is easily retrievable. Clearer guidance on when to assess frailty may also enhance information provision to care staff in other sectors, resulting in more appropriate clinical and social care.</p
A clinical audit of the electronic data capture of dementia in ambulance service patient records
No full textBackground: Dementia is a common diagnosis in older people. It is important to identify and record dementia on emergency call-outs, as it impacts on subsequent care decisions. Ambulance services are changing from paper to electronic patient records (EPRs), but there is limited data on how frequently and in which sections of the EPR dementia is being recorded. Aims: To audit the proportion of ambulance EPRs where dementia is recorded for patients aged (i) 65 and above; (ii) 75 and above, and to describe the sections in the EPR in which dementia is recorded, as there is currently no standardised button or field available to be used.Results: A total of 314,786 EPRs were included in the audit, over a one year period. The proportion of attended calls with ‘dementia’ recorded in the EPR in patients 65+ was 13.5%, increasing to 16.5% in patients aged 75+, which is similar to that recorded in previous literature. For patients aged 75+ conveyed to hospital, 15.2% had ‘dementia’ recorded in the EPR, which may indicate under-recording. Recording of dementia between Clinical Commissioning Groups varied between 11.0% and 15.3%. Dementia was recorded in 16 different free-text fields, and 38.4% of records had dementia recorded in more than one field.Conclusion: This audit demonstrates high variability in both the frequency of recording dementia and also the location in the EPR. To ensure consistent recording and ease of retrieval to inform patient care and handover, we propose the EPR should be modified to reflect paramedics’ needs, and those of the healthcare staff who receive and act on the report. Enhanced training for paramedics in the importance and method of recording dementia is required. Future data will enable accurate monitoring of trends in conveyance, and inform justifications for alternative services and novel referral pathways
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
