STUDY DESIGN Retrospective Case Series. OBJECTIVE To determine if extradural, intradural extramedullary, and intramedullary spinal neoplasms can be safely resected through a minimally invasive corridor. SUMMARY OF BACKGROUND DATA The use of minimally invasive approaches for resection of spinal neoplasms has been described for intradural schwannomas and(More)
INTRODUCTION Surgical activity is probably the most important component of surgical training. During the first year of surgical residency, there is an early opportunity for the development of surgical skills, before disparities between the skill sets of residents increase in future years. It is likely that surgical skill is related to operative volumes.(More)
OBJECTIVE The aim of this study was to assess the feasibility of incorporating the Delphi process within the simplifying conditions method (SCM) described in elaboration theory (ET) to identify conditions impacting the complexity of procedural skills for novice learners. METHODS We generated an initial list of conditions impacting the complexity of lumbar(More)
BACKGROUND Postgraduate neurosurgical education is undergoing significant reform, including transition to a competency-based training model. To support these efforts, the purpose of this study was to determine neurosurgical graduates' and program directors' (PDs) opinions about graduates' level of competence in reference to the 2010 Royal College Objectives(More)
OBJECT In recent years, dramatic changes in surgical education have increased interest in simulation-based training for complex surgical skills. This is particularly true for endoscopic third ventriculostomy (ETV), given the potential for serious intraoperative errors arising from surgical inexperience. However, prior to simulator development, a thorough(More)
CONTEXT For nearly 40 years, outcome-based models have dominated programme evaluation in health professions education. However, there is increasing recognition that these models cannot address the complexities of the health professions context and studies employing alternative evaluation approaches that are appearing in the literature. A similar paradigm(More)
CONTEXT Interest in applying cognitive load theory in health care simulation is growing. This line of inquiry requires measures that are sensitive to changes in cognitive load arising from different instructional designs. Recently, mental effort ratings and secondary task performance have shown promise as measures of cognitive load in health care(More)
Rapid technological advances and concern for patient safety have increased the focus on simulation as a pedagogical tool for educating health care providers. To date, simulation research scholarship has focused on two areas; evaluating instructional designs of simulation programs, and the integration of simulation into a broader educational context.(More)
As interest in applying cognitive load theory (CLT) to the study and design of pedagogic and technological approaches in healthcare simulation grows, suitable measures of cognitive load (CL) are needed. Here, we report a two-phased study investigating the sensitivity of subjective ratings of mental effort (SRME) and secondary-task performance (signal(More)
