Importance and Presence of High-Quality Evidence for Clinical Decisions in Neurosurgery: International Survey of Neurosurgeons.

Background: The publication rate of neurosurgical guidelines has increased tremendously over the past decade; however, only a small proportion of clinical decisions appear to be based on high-quality evidence.

Objective: The aim was to evaluate the evidence available within neurosurgery and its value within clinical practice according to neurosurgeons.

Methods: A Web-based survey was sent to 2552 neurosurgeons, who were members of the European Association of Neurosurgical Societies.
