APPY1 Test is a potentially useful diagnostic tool to rule out AA in this population, with clinical utility primarily in those patients classified as having low clinical risk of appendicitis according to the AS.

Objective. Main objective was whether the combination of C-Reactive Protein (CRP) and Alvarado Score (AS) increase the diagnosis accuracy of AS among 2-to-20-year-old patients with suspected acute appendicitis presenting to Emergency Departments. Materials and methods. This is a secondary analysis of prospective cohort study consecutively including all patients from 2 to 20 years of age attended for suspected acute appendicitis in 4 Spanish Emergency Departments during 6-month period. We collected demographic, clinical, analytic and radiographic, and surgical data. AS categories were retrospectively calculated as low (0-4 points), intermediate (5-6 points) or high (7-10 points). The cut-off levels were >0.5 mg/dl for CRP. The outcome was diagnosis of acute appendicitis within 14 days of the index visit. Results. A total of 331 patients with suspected of acute appendicitis (mean age 11.8 (SD 3.8) years; 52.9% males) were recruited. According to AS, 108 (32.6%) were at low risk, 76 at (23.0%) intermediate risk and 147 (44.4%) at high risk of acute appendicitis. One hundred and sixteen (35.0%) cases had confirmed histopathological diagnosis of acute appendicitis. The AUCs of ROC were 0.76 (0.70-0.81) for AS and 0.79 (95% CI 0.75-0.84) for CRP-AS being the difference statistically significant (p=0.003). The CRP for diagnosis acute appendicitis in low risk AS group had negative predictive value of 95.8% (95%CI 87.3-98.9) and likelihood ratio negative of 0.4 (95%CI 0.2-1.0). Conclusions. CRP-AS has shown to increase the diagnostic accuracy of AS for acute appendicitis. This approach may be useful to rule out the diagnosis of acute appendicitis in paediatric patients attended for abdominal pain suggestive of acute appendicitis.

RESUMENEl manejo adecuado de los pacientes en los servicios de urgencias y emergencias puede llegar a ser lo suficientemente complejo como para requerir una sóli-da formación que debiera estar sustentada en una especialidad médica, como ocurre en la mayoría de países de nuestro entorno.En la actualidad, en España no existe una formación reglada y homogénea en medicina de urgencias y emergencias (MUE) ni durante el período de formación de pregrado (en forma de asignatura obligatoria de forma universal en las facultades de medicina) ni durante el período de posgrado (en forma de especialidad médica). En este sentido, actualmente se está pendiente de la aprobación definitiva de esta especialidad en MUE en el marco de una reforma del programa de residencia que evolucionará hacia un programa formativo troncal de especialidades. A la espera de ello, la realidad es que en España los profesionales que desarrollan su labor en este ámbito asistencial poseen una formación heterogénea. Fruto de todo este vacío y de las necesidades formativas de estos profesionales, se ha desarrollado con los años un amplio abanico de propuestas formativas específicas para optimizar las habilidades y destrezas de los profesionales que prestan la primera asistencia urgente a los pacientes. Una nueva generación de cursos se ha puesto en marcha utilizando las nuevas metodologías didácticas de formación, en las que se incorporan herramientas didácticas de e-learning y simulación robótica.Palabras clave.

ABSTRACTThe appropriate care of patients in emergency services can reach a level of complexity as to make a sound training necessary, which should be based on a medical speciality, as happens in the majority of the countries in our context.In Spain at present there is no regulated and homogeneous training in urgency and emergency medicine (UEM), either during the period of undergraduate training (in the form of a universally compulsory subject in the faculties of medicine) or during the postgraduate period (in the form of a medical speciality). In this respect, the definitive approval of the speciality in UEM is currently pending within the framework of a reform of the residence program that will evolve towards a core training program of specialities. Until thus occurs, the reality in Spain is that professionals who work in this care setting possess a heterogeneous training. As a result of this vacuum and the training needs of these professionals, a wide range of specific training proposals has been developed over the years in order to optimise the skills and abilities of the professionals who provide initial emergency care to the patient.A new generation of courses has been set underway using the new didactic methodologies of training, into which didactic tools of e-learning and robotic simulation have been incorporated.
