The movement to create guidelines for management of medical maladies has been gaining strength for quality, academic, financial and political purposes over the past two decades. This applies to neurological diseases, too. Evidence-based guidelines created in a multidisciplinary fashion using predetermined criteria for grading scientific data and translating this to similarly ranked recommendations is a valuable approach to meeting this goal. The following is a summary of the methods used for, and the results of, an evidence-based guideline for the management of newly diagnosed glioblastoma. In addition to outlining recommendations by discipline, it also addresses how concerns and conflicts were addressed in their development and provides comment on future directions in management of this situation that may improve outcome. It is important that clinicians directly experienced in patient management take the lead in creation of guidelines related to the diseases they deal with, as these clinicians are clearly the most suited to being able to arrive at a meaningful and useful product.
