RESUMO
OBJECTIVES: Script concordance tests (SCTs) can be used to assess clinical reasoning, especially in situations of uncertainty, by comparing the responses of examinees with those of emergency physicians. The examinee's answers are scored based on the level of agreement with responses provided by a panel of experts. Emergency physicians are frequently uncertain in the interpretation of ECGs. Thus, the aim of this study was to validate an SCT combined with an ECG. METHODS: An SCT-ECG was developed. The test was administered to medical students, residents and emergency physicians. Scoring was based on data from a panel of 12 emergency physicians. The statistical analyses assessed the internal reliability of the SCT (Cronbach's α) and its ability to discriminate between the different groups (ANOVA followed by Tukey's post hoc test). RESULTS: The SCT-ECG was administered to 21 medical students, 19 residents and 12 emergency physicians. The internal reliability was satisfactory (Cronbach's α=0.80). Statistically significant differences were found between the groups (F(0.271)=21.07; p<0.0001). Moreover, significant differences (post hoc test) were detected between students and residents (p<0.001), students and experts (p<0.001), and residents and experts (p=0.017). CONCLUSIONS: This SCT-ECG is a valid tool to assess clinical reasoning in a context of uncertainty due to its high internal reliability and its ability to discriminate between different levels of expertise.

The COVID-19 pandemic led to sustained surveillance efforts, which made unprecedented volumes and types of data available. In Belgium, these data were used to conduct a targeted and regular assessment of the epidemiological situation. In addition, management tools were developed, incorporating key indicators and thresholds, to define risk levels and offer guidance to policy makers. Categorizing risk into various levels provided a stable framework to monitor the COVID-19 epidemiological situation and allowed for clear communication to authorities. Although translating risk levels into specific public health measures has remained challenging, this experience was foundational for future evaluation of the situation for respiratory infections in general, which, in Belgium, is now based on a management tool combining different data sources.

Coronavirus Disease 2019 (COVID-19) vaccination has resulted in excellent protection against fatal disease, including in older adults. However, risk factors for post-vaccination fatal COVID-19 are largely unknown. We comprehensively studied three large nursing home outbreaks (20-35% fatal cases among residents) by combining severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) aerosol monitoring, whole-genome phylogenetic analysis and immunovirological profiling of nasal mucosa by digital nCounter transcriptomics. Phylogenetic investigations indicated that each outbreak stemmed from a single introduction event, although with different variants (Delta, Gamma and Mu). SARS-CoV-2 was detected in aerosol samples up to 52 d after the initial infection. Combining demographic, immune and viral parameters, the best predictive models for mortality comprised IFNB1 or age, viral ORF7a and ACE2 receptor transcripts. Comparison with published pre-vaccine fatal COVID-19 transcriptomic and genomic signatures uncovered a unique IRF3 low/IRF7 high immune signature in post-vaccine fatal COVID-19 outbreaks. A multi-layered strategy, including environmental sampling, immunomonitoring and early antiviral therapy, should be considered to prevent post-vaccination COVID-19 mortality in nursing homes.

OBJECTIVES: The aim of this study was to establish whether price list information could reduce laboratory and radiological examination costs in emergency departments (EDs). MATERIALS AND METHODS: A prospective survey of adult (>16 years old) admissions was conducted at the ED of a university hospital in Belgium. Nine resident emergency physicians were followed for a span of 6 months, which was divided into 2-month periods: control (October and November 2011), intervention (December 2011 to January 2012), and washout (February and March 2012). Laboratory and radiological costs for each of the daily admissions were calculated during the respective periods and compared. RESULTS: A total of 3758 patients were registered: 1093 in period 1 (control), 1329 in period 2 (intervention), and 1336 in period 3 (washout). We observed significant reductions in examination costs: 10.73% (P=0.015) for laboratory and 33.66% (P<0.001) for radiological costs in period 2 versus period 1; 5.02% (P=0.014) for laboratory and 40.00% (P<0.001) for radiological costs in period 3 versus period 1. In addition, we found that laboratory examination costs increased slightly between periods 2 and 3 (+6.4%), whereas costs related to radiologic examinations continued to decrease (-10.16%); however, these differences were not statistically significant. CONCLUSION: We conclude that the distribution of price lists at EDs promotes cost awareness, which can result in significant decreases in examination costs.

OBJECTIVES: To develop and assess the reliability of a script concordance test (SCT) to evaluate pharmacy students' clinical reasoning when facing basic emergency situations. DESIGN: A first aid course was designed that consisted of 8 weekly instructional sessions (4 on internal medicine, including life threatening situations; 2 on pediatrics; and 2 on trauma) in which the instructor presented case studies in a small-group format. In the first and final sessions of the course, a practice SCT was administered to familiarize students with the test format. ASSESSMENT: A 66-question SCT examination was administered to the 68 third-year pharmacy students enrolled in the first aid course. The students' mean score was 68.5% ± 9.8% and panel members' mean score was 86.5% ± 4.2%. Twenty students were selected randomly to complete a course survey and 85% indicated they were satisfied with using the SCT. CONCLUSIONS: A first aid SCT was found to be both a practical and reliable testing instrument for assessing the clinical reasoning of pharmacy students in basic emergency situations.

Cough is a frequent reason for ED consultation. When one considers the epidemiological data, whooping cough must be considered in the differential of subacute cough. Clinical symptomatology is slightly different in the adult and unvaccinated child. An infection by Bordetella pertussis should be suspected when the history shows a persistent cough for more than 1 week in conjunction with other clinical elements. Several methods are available to establish a diagnosis: culture, PCR and bacterial serology. An early diagnosis will allow effective treatment, limit the transmission to unvaccinated infants, reduce complications and prevent extensive and expensive check-ups for chronic cough.
