Diagnostic 5

#1

Comment évaluer la virulence d'un pathogène ?

La virulence peut être évaluée par des tests de culture, des modèles animaux et des analyses génétiques.
Virulence Pathogénie

Quels tests sont utilisés pour diagnostiquer une infection virulente ?

Des cultures microbiologiques, des tests PCR et des sérologies sont couramment utilisés.
Infections Tests de diagnostic
#3

La virulence peut-elle être mesurée quantitativement ?

Oui, des indices comme le LD50 (dose létale) permettent de quantifier la virulence.
Virulence Dose létale
#4

Quels signes cliniques indiquent une virulence élevée ?

Une virulence élevée se manifeste par des symptômes graves, une progression rapide de la maladie.

#5

Comment les tests génétiques aident-ils au diagnostic ?

Les tests génétiques identifient des gènes de virulence spécifiques, facilitant le diagnostic.

#4

Les complications varient-elles selon le pathogène ?

Oui, chaque pathogène peut entraîner des complications spécifiques en fonction de sa virulence.
Pathogénie Complications
#5

Quels facteurs aggravent les complications virulentes ?

L'âge, les comorbidités et l'immunodépression peuvent aggraver les complications virulentes.
Facteurs de risque Immunodépression

Facteurs de risque 5

#1

Quels sont les principaux facteurs de risque de virulence ?

Les facteurs incluent l'âge, l'état immunitaire, les maladies chroniques et l'exposition environnementale.

#2

L'immunodépression augmente-t-elle la virulence ?

Oui, les personnes immunodéprimées sont plus susceptibles de développer des infections virulentes.
Immunodépression Virulence
#3

Comment l'environnement influence-t-il la virulence ?

Des conditions environnementales comme l'hygiène et la densité de population affectent la virulence.
Environnement Transmission
#4

Les habitudes de vie peuvent-elles affecter la virulence ?

Oui, des habitudes comme le tabagisme et l'alcoolisme peuvent augmenter le risque d'infections virulentes.
Habitudes de vie Facteurs de risque
#5

Les voyages augmentent-ils le risque de virulence ?

Oui, les voyages peuvent exposer à des agents pathogènes virulents non présents localement.

Direct transportation to a thrombectomy-capable intervention center is beneficial for patients with ischemic stroke due to large vessel occlusion (LVO), but can delay intravenous thrombolytics (IVT). ... We used data from two prospective cohort studies in the Netherlands: the Leiden Prehospital Stroke Study and the PRESTO study. We included stroke code patients within 6 h from symptom onset. We modele... We included 1798 stroke code patients from four ambulance regions. Per region, overtriage ranged from 1-13% (RACE triage) and 3-15% (personalized tool). Reduction of delay to EVT varied by region betw... In this modeling study, we showed that prehospital triage reduced time to EVT without disproportionate IVT delay, compared to a drip-and-ship strategy. The effect of triage strategies and the associat...

Triage performance of PAX1

In this study, we aimed to validate the performance of the PAX1 and JAM3 methylation (PAX1... The triage performance of liquid-based cytology (LBC) and the PAX1... In total, 1851 participants had cervical histological outcomes and were included in the analysis. The sensitivity/specificity of the LBC test results with atypical squamous cells of undetermined signi... In non-16/18 hrHPV(+) women, PAX1...

Triaging and referring in adjacent general and emergency departments (the TRIAGE-trial): A process evaluation of medical staff experiences in a nurse-led triage system.

This process evaluation aims at identifying the facilitators and inhibitors that influenced the successful uptake of a nurse-led triage system streaming low-risk patients from an emergency department ... Semi-structured interviews with ED nurses (n = 12), ED doctors (n = 6) from the ED of a Belgian general hospital and GPs (n = 5) affiliated with the adjacent GP cooperative (GPC). The process evaluati... Through a deductive framework, facilitators and inhibitors could be identified on three levels: the organisational, group and individual level. Main inhibitors are the degree of risk aversion of indiv... Based on the process evaluation we can conclude that a consensus exists among stakeholders that the ED Nurses are considered ideally positioned to perform the triage of walk-in patients, although a ce...

Effect of triage training on nurses' practice and triage outcomes of patients with acute coronary syndrome.

Accurate assessment and prompt management of patients with acute coronary syndrome (ACS) is a complex process for emergency department (ED) nurses and has variable clinical outcomes. The aim of the pr... In this quasi-experimental study, a pretest-posttest group of 24 nurses were included by convenience sampling method and 960 patients with ACS were selected by sequential sampling during the pre-inter... The overall mean score of the triage nurses' practice and its subscales, including Primary monitoring and assessment, cardiovascular risk factors assessment, evaluation of coronary heart disease (CHD)... The development of a cardiac triage-specific educational program could improve the performance of nurses in the evaluation and management of patients with ACS, but had no effect on the triage outcomes...

Daily triage audit can improve nurses' triage stratification: A pre-post study.

The objective was to evaluate whether the error rate in the application of the triage system decreased after the introduction of daily auditing, and it was also evaluated if the agreement rate between... A quasi-experimental study was performed with a pre-post design, between June 2019 and June 2021 in one emergency department.... The accuracy and error rate of triage in the pre- and post-intervention period were compared. Univariate and multivariate logistic regression analyses were performed to explore the relationships betwe... Nine hundred four patients were enrolled in the pre-intervention period and 869 in the post-intervention period. The error rate in the pre-intervention period was 23.3% and in the post-intervention pe... Daily auditing is a clinical procedure that improves the nurse's application of the triage system. Daily auditing has reduced errors by the nurse, improving performance and concordance with the physic... Triage systems are a key point for the stratification of the priority level of patients and it is therefore evident that they maintain high-quality standards. Through the practice of daily auditing, n... The study did not involve any patients during its conduction....

Pediatric emergency triage systems.

The aim of this study was to perform a narrative review of the leading pediatric triage systems in emergency departments (EDs).... Articles published between 1999 and 2019 were identified by searching the MEDLINE, EMBASE, and PubMed databases using the keywords "pediatric triage", "pediatric assessment tools", and "emergency depa... A total of 105 articles on pediatric emergency triage systems in 12 countries were evaluated. Triage systems were divided into two groups: color-stratified triage systems and alert systems. The color-... These are fundamental tools for risk classification of patients seeking treatment in EDs. Not all triage systems have been assessed for validity and reliability; nor are they well suited for all regio...
