چکیده

OBJECTIVE/HYPOTHESIS Simulation models can help develop procedural skills outside the clinical setting while also providing a means for evaluation of trainees. Objective Structured Assessment of Technical Skills (OSATS) have been developed for several procedures. The purpose of this study was to demonstrate the construct validity of an OSATS for microvascular anastomosis performed on a simulation model using chicken thigh vessels. STUDY DESIGN Validation study. METHODS An expert panel constructed a task-specific checklist for an OSATS for microvascular anastomosis. Twenty surgical staff and trainees performed a microvascular anastomosis of a chicken ischiatic artery. Training level and microsurgical experience were assessed by questionnaire. The performances were recorded and scored by two experts using the task-specific and global scales of the OSATS. RESULTS Analysis of variance revealed a significant effect of training and microvascular experience for both the task-specific score and global rating scale score (P < .005). Interrater reliability was 0.7. Experience level demonstrated a logarithmic relationship with task time. CONCLUSIONS The microvascular OSATS applied to the chicken thigh simulator model differentiated between levels of microvascular experience. It demonstrated construct validity and reliability for the assessment of procedural competence using a cost-effective and easily accessible model.

Background: Various prediction models have been developed aiming to estimate risk-adjusted mortality, morbidity and length of intensive care unit stay following cardiac surgeries. The European system for cardiac operative risk evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death. The objective of this study was to evaluate the perf...

The Effects of Continuous Cognitive Task on Postural Control of People with Anterior Cruciate Ligament Reconstruction Using Balance Error Scoring System

Objective: People with Anterior Cruciate Ligament (ACL) reconstruction need to have almost automatic postural control to focus on their athletic skills. Continuous cognitive task is a method for removing attention from postural control. The effects of continuous cognitive task on postural control of people with ACL reconstruction has been assessed by laboratory tools; however, its effect using ...

Automatic Generation of a Multi Agent System for Crisis Management by a Model Driven Approach

Considering the increasing occurrences of unexpected events and the need for pre-crisis planning in order to reduce risks and losses, modeling instant response environments is needed more than ever. Modeling may lead to more careful planning for crisis-response operations, such as team formation, task assignment, and doing the task by teams. A common challenge in this way is that the model shou...

Groundwater recharge simulation using a coupled saturated-unsaturated flow model

Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...
