In recent years, the utilization of big data to visualize the real-world status of medical care has received greater attention. Since 2011, the authors have studied a nationwide cohort study named the J-ASPECT Study based on the Japanese Diagnosis Procedure Combination(DPC) and claim database. Here we first describe the overall profile of the joint project conducted by this study group and the Japan Neurosurgical Society as the special project of the 34th Annual Meeting of the Japanese Congress of Neurological Surgeons. Briefly, we built a large scale database of the patients who were admitted for the treatment of neurosurgical diseases, and other cerebrovascular disorders from hospitalization until discharge. Next, we focused on the current status of surgical and endovascular management for patients with subarachnoid hemorrhage, unruptured aneurysms, and carotid stenosis treated during the period of April 2012 to March 2013 in the hospitals participating in this study.
