Usability Study of the ECIC Learning System
The aim of the ECIC project is the dissemination of participative methods of organizational development originating from Scandinavian countries to other European countries. To support this process we developed a hypertextual learning system. Because of the heterogeneous target group and the illstructured domains of ECIC detailed usability testing is necessary. First tentative results indicate t...
متن کاملPostoperative evaluation of changes in extracranial-intracranial bypass graft using superficial temporal artery duplex ultrasonography.
BACKGROUND AND PURPOSE Extracranial-intracranial (ECIC) bypass grafts have been assessed postoperatively by various neuroradiologic techniques. The aim of this prospective study was to evaluate postoperative changes in ECIC bypass graft by using superficial temporal artery duplex ultrasonography (STDU). Furthermore, this study assessed the ability of STDU to predict cerebrovascular reserve capa...
متن کاملProposing a validated clinical app predicting hospitalization cost for extracranial-intracranial bypass surgery
OBJECT United States healthcare reforms are focused on curtailing rising expenditures. In neurosurgical domain, limited or no data exists identifying potential modifiable targets associated with high-hospitalization cost for cerebrovascular procedures such as extracranial-intracranial (ECIC) bypass. Our study objective was to develop a predictive model of initial cost for patients undergoing by...
متن کاملQuantitative measurement of cerebrovascular reactivity by blood oxygen level-dependent MR imaging in patients with intracranial stenosis: preoperative cerebrovascular reactivity predicts the effect of extracranial-intracranial bypass surgery.
BACKGROUND AND PURPOSE CVR is a measure of cerebral hemodynamic impairment. A recently validated technique quantifies CVR by using a precise CO(2) vasodilatory stimulus and BOLD MR imaging. Our aim was to determine whether preoperative CO(2) BOLD CVR predicts the hemodynamic effect of ECIC bypass surgery in patients with intracranial steno-occlusive disease. MATERIALS AND METHODS Twenty-five ...
متن کاملThe extracranial/intracranial bypass study.
PHYSICIANS IN their eagerness to help patients often become enthusiastic or supportive of a particular therapy based on their own limited experience or on the anecdotal experiences of others before there is clear evidence that a particular treatment is useful or effective. Many treatments are proposed and carried out often at great expense and sometimes with considerable risk long before there ...
