Enhancing Authenticity in Simulation Using Appropriate Techniques of Moulage

Workshop Overview The use of special effects (moulage) is a way to augment the authenticity of a scenario in simulation. This workshop will introduce different techniques of moulage (oil based cream colors, watercolors, transfer tattoos and 3D Prosthetics). The participants will have the opportunity to explore these techniques by applying various moulages. They will compare the techniques and discuss their advantages and disadvantages. Moreover, strategies for standardization and quality assurance will be discussed. Workshop Rationale Moulage supports the sensory perception in an scenario (1). It can provide evaluation clues (2) and help learners (and SPs) to engage in the simulation. However, it is of crucial importance that the simulated physical pathologies are represented accurate and reliable. Accuracy is achieved by using the appropriate technique, which requires knowledge and practice . With information about different moulage techniques, we hope to increases the knowledge of moulage during the workshop. By applying moulages in various techniques we will practice together. As standardization is critical for simulation scenarios in assessment (3, 4) strategies for standardization of moulage will be introduced and discussed. Workshop Objectives During the workshop participants will: - gain knowledge about different techniques of moulages - practice moulages in various techniques - discuss the advantages and disadvantages of moulage techniques - describe strategies for standardization and quality assurance of moulage Planned Format 5 min Introduction 15 min Overview – Background & Theory (presentation) 15 min Application of moulage for ankle sprain in 4 different techniques (oil based cream color, water color, temporary tatoo, 3D prosthetic) in small groups 5 min Comparing the results by interactive viewing of prepared moulages 15 min Application of moulages for burn in different techniques in small groups 5 min Comparing results the results by interactive viewing of prepared moulages 5 min Sharing experiences with different techniques in small groups 20 min Discussion of the techniques including standardization and quality assurance strategies (plenary discussion) 5 min Summary / Take home points

Antifactor Xa Activity for the Management of Anticoagulation during Cardiac Surgery

Background In patients with autoimmune diseases associated with antiphospholipid antibodies, precise management of anticoagulation during extracorporeal circulation (ECC) is complicated. It was the aim of the present study to determine whether antifactor Xa (aXa) activity is useful in guiding heparin therapy during ECC. Methods In 15 patients undergoing cardiac surgery, anticoagulation with unfractionated heparin (UFH) and its reversal with protamine were guided using activated clotting time (ACT) (>400 second during ECC; ≤100 second for UFH reversal). For each ACT, the corresponding aXa activity levels were measured. Results A total of 144 blood samples were obtained. ACT and aXa activity were significantly correlated (r = 0.771, p< 0.0001, Spearman rank-order correlation). Using receiver operating characteristic curve (ROC) analyses, the cutoffvalues for aXa activity were 1.14 IU/mL (area under the ROC curve [AUC]: 0.89; inaccuracy rate: 9.4%) to predict ACT > 400 seconds and 0.55 IU/mL (AUC: 0.85; inaccuracy rate: 13.3%) for ACT ≤ 100 seconds. Conclusion AXa activity is strongly correlated with ACT, and therefore may be feasible for managing anticoagulation with UFH during ECC.

Dysphagia in Acute Stroke: Incidence, Burden and Impact on Clinical Outcome.

BACKGROUND Reported frequency of post-stroke dysphagia in the literature is highly variable. In view of progress in stroke management, we aimed to assess the current burden of dysphagia in acute ischemic stroke. METHODS We studied 570 consecutive patients treated in a tertiary stroke center. Dysphagia was evaluated by using the Gugging Swallowing Screen (GUSS). We investigated the relationship of dysphagia with pneumonia, length of hospital stay and discharge destination and compared rates of favourable clinical outcome and mortality at 3 months between dysphagic patients and those without dysphagia. RESULTS Dysphagia was diagnosed in 118 of 570 (20.7%) patients and persisted in 60 (50.9%) at hospital discharge. Thirty-six (30.5%) patients needed nasogastric tube because of severe dysphagia. Stroke severity rather than infarct location was associated with dysphagia. Dysphagic patients suffered more frequently from pneumonia (23.1% vs. 1.1%, p<0.001), stayed longer at monitored stroke unit beds (4.4±2.8 vs. 2.7±2.4 days; p<0.001) and were less often discharged to home (19.5% vs. 63.7%, p = 0.001) as compared to those without dysphagia. At 3 months, dysphagic patients less often had a favourable outcome (35.7% vs. 69.7%; p<0.001), less often lived at home (38.8% vs. 76.5%; p<0.001), and more often had died (13.6% vs. 1.6%; p<0.001). Multivariate analyses identified dysphagia to be an independent predictor of discharge destination and institutionalization at 3 months, while severe dysphagia requiring tube placement was strongly associated with mortality. CONCLUSION Dysphagia still affects a substantial portion of stroke patients and may have a large impact on clinical outcome, mortality and institutionalization.

Sural nerve conduction studies using ultrasound-guided needle positioning: Influence of age and recording location.

INTRODUCTION The aim of this study was to compare orthodromic sural nerve conduction study (NCS) results using ultrasound-guided needle positioning (USNP) to surface electrode recordings. METHODS 51 healthy subjects aged 24 - 80 years, divided into 5 age groups, were examined. Electrical stimuli were applied behind the lateral malleolus. Sensory nerve action potentials (SNAPs) were recorded 8 and 15 cm proximally with surface and needle electrodes. RESULTS Mean SNAP amplitudes in µV (surface/needle electrodes) averaged 12.7 (SD 7.6)/40.6 (SD 20.8), P<0.001, for subjects aged 20-29 years, and 5.0 (SD 2.4)/19.8 (SD 9.8), P<0.01, for subjects aged > 60 years. SNAP amplitudes were smaller at the proximal recording location. DISCUSSION NCS using USNP yield higher amplitude responses than surface electrodes in all age groups at all recording sites. SNAP amplitudes are smaller at proximal recording locations due to sural nerve branching. This article is protected by copyright. All rights reserved.

Improving the Assessment of Communication Skills at the Swiss Federal Licensing Exam: Results of a Student's Needs Assessment

Introduction With a three year project the assessment of communication skills within the Swiss Federal Licensing Examinations (FLE) shall be improved. As a first step a needs assessment among communication experts and medical students of the Swiss Medical Faculties will be performed. In this presentation the results of the students’ needs assessment will be presented. Methods A bilingual student’s online questionnaire will be developed by an expert panel taking relevant literature, the Swiss Catalogue of Learning Objectives and other consensus statements for communication (e.g., the European and Basler consensus statements) into account. With a think aloud study response process validity evidence will be sought. The questionnaire will focus on the following topics related to communication skills: (1) What has been taught?, (2) What has been assessed in the faculty exams?, (3) What has been assessed in the FLE?, (4) What should have been assessed in the FLE and how should the assessment be improved? Results Results of the students’ needs assessment will be available by the end of 2015 and be presented. Conclusions/ Take-home message We hope for valuable input for improving the assessment of communications skills within the FLE also from the students’ side. Results of the needs assessment from the students and experts will be combined and taken as input for an international expert symposium on how to improve the communication skills assessment within the FLE.
