Objective: To validate a simple risk score to predict bacteremia (MPB5-Toledo) in patients seen in the emergency departments (ED) due to infections.

Methods: Prospective and multicenter observational cohort study of the blood cultures (BC) ordered in 74 Spanish ED for adults (aged 18 or older) seen from October 1, 2019, to February 29, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC).

The aim was to develop a predictive model of infection by multidrug-resistant microorganisms (MDRO). A national, retrospective cohort study was carried out including all patients attended for an infectious disease in 54 Spanish Emergency Departments (ED), in whom a microbiological isolation was available from a culture obtained during their attention in the ED. A MDRO infection prediction model was created in a derivation cohort using backward logistic regression.

Objectives: To build a model to predict 30-day mortality and compare it to prediction based on the Mortality in Emergency Department Sepsis (MEDS) score in patients aged 75 years or older treated for infection and systemic inflammatory response syndrome (SIRS) in the emergency department.

Material And Methods: Prospective analysis of a convenience cohort of patients aged 75 years or older treated for infection and SIRS in 13 Spanish emergency departments in 2013. We recorded demographic variables; comorbidity; risk factors for poor outcome; functional dependence at baseline; site of infection; and hemodynamic, clinical and laboratory findings on start of care.

Objectives: To develop the INFURG-SEMES scale (based on the emergency infections study of the Spanish Society of Emergency Medicine) using clinical and laboratory data to diagnose acute appendicitis (AA) in patients aged 2 to 20 years who were evaluated in hospital emergency departments and to compare its diagnostic yield to that of the Alvarado score.

Material And Methods: Prospective observational cohort study enrolling consecutive patients between the ages of 2 and 20 years who came to 4 hospital emergency departments with abdominal pain suggestive of AA and of less than 72 hours' duration. We collected demographic, clinical, analytic (white blood cell count, differential counts, and C-reactive protein [CRP] levels), and radiographic data (ultrasound and/or computed tomography scans).

Objective: To describe the clinical characteristics and outcomes of elderly patients (≥ 75 years) with suspected infection attending the emergency department (ED) and to compare patients admitted to a short-stay unit (SSU) with those admitted to a conventional hospital unit (CHU).

Material And Methods: Prospective cohort study including, using opportunity sampling, patients ≥75 years treated for infection in the ED of 3 Spanish university hospitals (2013). Demographic variables, comorbidity, baseline performance status, presence of sepsis, infection type, destination on discharge, and mortality at 30 days were collected.

Objective: Evaluate the diagnostic accuracy of the APPY1 Test alone and in combination with the Alvarado score (AS) to rule out acute appendicitis (AA) in patients presenting to EDs with abdominal pain suspicious for AA.

Methodology: Observational study in a prospective consecutive cohort including all patients from 2 to 20 years with abdominal pain suggestive of AA in four EDs. The APPY1 Test was performed and AS was calculated to determine risk stratification for each patient.

Objective: To determine the clinical profile and the initial management of elderly patients with acute infections attending Spanish Emergency Departments (EDs), and to analyse whether there are any differences compared to younger adults.

Material And Methods: A descriptive, cross-sectional, multicentre study using the data recorded in the INFURG-SEMES register. It included a total of 79,654 of 15 years or over treated for an acute infection in 49 Spanish EDs between 10 October 2010 and 20 September 2011.

Objectives: To analyse factors associated with short-term mortality in elderly patients seen in emergency departments (ED) for an episode of infectious disease.

Materials And Methods: A prospective, observational, multicentre, analytical study was carried out on patients aged 75years and older who were treated in the ED of one of the eight participating hospitals. An assessment was made of 26 independent variables that could influence mortality at 30days.

Objective: To determine the validity of the classic sepsis criteria or systemic inflammatory response syndrome (heart rate, respiratory rate, temperature, and leukocyte count) and the modified sepsis criteria (systemic inflammatory response syndrome criteria plus glycemia and altered mental status), and the validity of each of these variables individually to predict 30-day mortality, as well as develop a predictive model of 30-day mortality in elderly patients attended for infection in emergency departments (ED).

Methods: A prospective cohort study including patients at least 75 years old attended in three Spanish university ED for infection during 2013 was carried out. Demographic variables and data on comorbidities, functional status, hemodynamic sepsis diagnosis variables, site of infection, and 30-day mortality were collected.

Objectives: To compare the efficiency of short-stay units (SSUs) managed by different departments within hospitals.

Material And Methods: Cross-sectional study in 40 hospitals with SSUs. From June 1 to December 31, 2012,we gathered data on clinical caseloads and management.

Microscopic pulmonary tumour embolism is a rare cause of pulmonary hypertension. In most of the reported cases, symptoms develop over several days or weeks in patients previously diagnosed with malignant diseases. In our case, a 41-year-old man with an unremarkable medical history presented with respiratory failure that led to death less than 48 h from the onset of symptoms.
