Use of simulation training to teach the ABCDE primary assessment:an observational study in a Dutch University Hospital with a 3-4 months follow-up

Objectives To investigate short-term and long-term effectiveness of simulation training to acquire a structured Airway Breathing Circulation Disability Exposure (ABCDE) approach for medical emergencies; and to examine which skills were learnt and maintained best. Design An observational study with a 3-4 months follow-up. Setting Skills center of the University Medical Center Groningen. Participants Thirty voluntary participants (21 females and 9 males; 27±2.77 years) of a simulation-based course. Intervention A 2-day ABCDE-teaching course for residents and non-residents. The course encompasses 24 simulations in which participants perform primary assessments of acute ill patients. Video recordings were taken of each participant performing a primary assessment, before (T1), directly after (T2) and 3-4 months after the intervention (T3). Main outcome measures Physicians' performance in the ABCDE primary assessment at T1, T2 and T3. Two observers scored the primary assessments, blinded to measurement moment, using an assessment form to evaluate the performance with regard to skills essential for a structured ABCDE approach. The Friedman and Wilcoxon signed-rank test were used to compare physicians' performances on the subsequent measurement moments. Results The mean ranks on the total primary assessment at T1, T2 and T3 were 1.14, 2.62 and 2.24, respectively, and were significantly different, (p<0.001). The mean ranks on the total primary assessment directly after the course (T2 vs T1 p<0.001) and 3-4 months after the course (T3 vs T1 p<0.001) were significantly better than before the course. Certain skills deteriorated during the follow-up. Strikingly, most skills that decrease over time are Crew Resources Management (CRM) skills. Conclusion A course using simulation training is an effective educational tool to teach physicians the ABCDE primary assessment. Certain CRM skills decrease over time, so we recommend organising refresher courses, simulation team training or another kind of simulation training with a focus on CRM skills

Improved detection of delirium, implementation and validation of the CAM-ICU in elderly Emergency Department patients

Objective To evaluate the effect of routine use of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) on the diagnosis rate of delirium in elderly Emergency Department (ED) patients and the validity of the CAM-ICU in the ED setting. Methods This was a prospective observational study in a tertiary care academic ED. We compared the diagnosis rate of delirium before implementation of the CAM-ICU, without routine use of a screening tool, with the diagnosis rate after implementation of the CAM-ICU. All consecutive patients aged 70 years or older were enrolled. The diagnosis rate before implementation was based on chart review and after implementation on a positive CAM-ICU score. In a subsample, the presence of delirium was evaluated independently according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., text revision (DSM-IV-TR) criteria to assess the validity of the CAM-ICU. Results The total study population included 968 patients: 490 before and 478 after implementation of the CAM-ICU. The two groups were not significantly different in patient characteristics. Before implementation of the CAM-ICU, delirium was diagnosed in 14 patients (3%) and after implementation in 48 patients (10%) (P Conclusion The diagnosis rate of delirium after implementation of the CAM-ICU was three-fold higher than before. The CAM-ICU is a reliable screening tool in the ED, with high sensitivity, specificity, and positive and negative predictive value. Copyright (c) 2017 Wolters Kluwer Health, Inc. All rights reserved

Pseudolithiasis after recent use of ceftriaxone:an unexpected diagnosis in a child with abdominal pain

<p>Ceftriaxone is a widely prescribed third-generation broad spectrum cephalosporin, often used for treatment of severe bacterial infections in children. It is known that ceftriaxone can cause sonographic biliary abnormalities in children. However, in only a minority of these cases, it will be accompanied with the clinical relevant symptoms and biochemical abnormalities seen in gallbladder disease. Ceftriaxone-associated cholelithiasis has a highly reversible nature and is thus called pseudolithiasis. Apart from stopping or converting the ceftriaxone treatment, no other therapy is indicated. Awareness of this phenomenon is important in preventing unnecessary treatment.</p>
