ObjectiveWe investigated the association between the publication of the Consolidated Standards of Reporting Trials extension for abstracts (CONSORT-EA) and other variables of interest on the quality of reporting of abstracts of randomised controlled trials (RCTs) published in emergency medicine (EM) journals.MethodsWe performed a survey of the literature, comparing the quality of reporting before (2005–2007) with after (2014–2015) the publication of the dedicated CONSORT-EA in 2008. The quality of reporting was measured as the sum of items of the CONSORT-EA checklist reported in each abstract, ranging from 0 to 15. The main explanatory variable was the period of publication: pre-CONSORT-EA versus post-CONSORT-EA public. Other explanatory variables were journal’s endorsement of the CONSORT statement, number of centres participating in the study, study’s sample size, type of intervention, significance of results, source of funding and study setting. We analysed the data using generalised estimation equations, performing a univariate and a multivariable analysis.ResultsWe retrieved 844 articles, and randomly selected 60 per period for review, after stratifying for journal. The mean (SD) number of items reported was 6.4 (1.9) in the period before and 6.9 (1.8) in the period after the publication of the CONSORT-EA, with an adjusted mean difference (aMD) of 0.47 (95% CI −0.13 to 1.06). Abstracts of trials of pharmacological interventions had a significantly larger mean number of reported items than those of trials of non-pharmacological interventions (aMD 1.59; 95% CI 0.94 to 2.24).ConclusionsThe quality of reporting in abstracts of RCTs published in EM journals is low and was not significantly impacted by the publication of a dedicated CONSORT-EA.
The Padua prediction score (PPS) has been suggested as the best available model for the assessment of the risk of venous thromboembolism (VTE) in hospitalized medical patients. The impact of its use in clinical practice has never been prospectively evaluated. According to a quasi-randomized study design, consecutive patients admitted to Internal Medicine Section 1 were allocated to a PPS-based decisional strategy suggesting thromboprophylaxis in patients with PPS score ≥4, and those admitted to Section 2 to a clinical judgment-based strategy. Study patients underwent complete compression ultrasonography of the lower limbs at discharge. The primary outcome was symptomatic or asymptomatic VTE during hospital stay. Secondary outcomes were VTE excluding isolated distal deep vein thrombosis, bleedings, and appropriate thromboprophylaxis. 628 patients were included in the analysis, 235 in the PPS group, and 393 in the clinical judgment group. The two groups differed for length of hospital stay, prevalence of recent trauma or surgery, and stroke. Compared with control, the PPS group had a significantly lower incidence of VTE (8.5 vs. 15.5 %, OR 0.51, 95 % CI 0.30-0.86), also after adjusting for thromboprophylaxis use and patient PPS-risk category (OR 0.54, 95 % CI 0.31-0.94). In conclusion, the use of PPS was associated with a higher rate of appropriate thromboprophylaxis prescription; no significant differences were found in the other secondary outcomes. The use of PPS for the assessment of risk for VTE is associated with a reduced incidence of VTE compared with the clinical judgment. These result needs to be confirmed in future studies.
ObjectiveWe aimed at identifying baseline predictive factors for emergency department (ED) readmission, with hospitalisation/death, in patients with COVID-19 previously discharged from the ED. We also developed a disease progression velocity index.Design and settingRetrospective cohort study of prospectively collected data. The charts of consecutive patients with COVID-19 discharged from the Reggio Emilia (Italy) ED (2 March 2 to 31 March 2020) were retrospectively examined. Clinical, laboratory and CT findings at first ED admission were tested as predictive factors using multivariable logistic models. We divided CT extension by days from symptom onset to build a synthetic velocity index.Participants450 patients discharged from the ED with diagnosis of COVID-19.Main outcome measureED readmission within 14 days, followed by hospitalisation/death.ResultsOf the discharged patients, 84 (18.7%) were readmitted to the ED, 61 (13.6%) were hospitalised and 10 (2.2%) died. Age (OR=1.05; 95% CI 1.03 to 1.08), Charlson Comorbidity Index 3 versus 0 (OR=11.61; 95% CI 1.76 to 76.58), days from symptom onset (OR for 1-day increase=0.81; 95% CI 0.73 to 0.90) and CT extension (OR for 1% increase=1.03; 95% CI 1.01 to 1.06) were associated in a multivariable model for readmission with hospitalisation/death. A 2-day lag velocity index was a strong predictor (OR for unit increase=1.21, 95% CI 1.08 to 1.36); the model including this index resulted in less information loss.ConclusionsA velocity index combining CT extension and days from symptom onset predicts disease progression in patients with COVID-19. For example, a 20% CT extension 3 days after symptom onset has the same risk as does 50% after 10 days.
Background
COVID-19 prognostic factors include age, sex, comorbidities, laboratory and imaging findings, and time from symptom onset to seeking care.
Purpose
The study aim was to evaluate indices combining disease severity measures and time from disease onset to predict mortality of COVID-19 patients admitted to the emergency department (ED).
Materials and methods
All consecutive COVID-19 patients who underwent both computed tomography (CT) and chest X-ray (CXR) at ED presentation between 27/02/2020 and 13/03/2020 were included. CT visual score of disease extension and CXR Radiographic Assessment of Lung Edema (RALE) score were collected. The CT- and CXR-based scores, C-reactive protein (CRP), and oxygen saturation levels (sO2) were separately combined with time from symptom onset to ED presentation to obtain severity/time indices. Multivariable regression age- and sex-adjusted models without and with severity/time indices were compared. For CXR-RALE, the models were tested in a validation cohort.
Results
Of the 308 included patients, 55 (17.9%) died. In multivariable logistic age- and sex-adjusted models for death at 30 days, severity/time indices showed good discrimination ability, higher for imaging than for laboratory measures (AUCCT = 0.92, AUCCXR = 0.90, AUCCRP = 0.88, AUCsO2 = 0.88). AUCCXR was lower in the validation cohort (0.79). The models including severity/time indices performed slightly better than models including measures of disease severity not combined with time and those including the Charlson Comorbidity Index, except for CRP-based models.
Conclusion
Time from symptom onset to ED admission is a strong prognostic factor and provides added value to the interpretation of imaging and laboratory findings at ED presentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
