Our study will include patients presenting in the clinic with a diagnosis of cerebral aneurysm. Patients for whom surgical intervention is deemed necessary will be approached for participation in the study. After signing informed consent, they will be randomized to receive a document that will serve as a decision aid (option grid). If they are randomized as controls they will receive a standard information booklet. Patients will be given a few minutes to read through the option grid choices, and will have the chance to ask questions about the two possible treatments (cerebral aneurysm clipping, cerebral aneurysm coiling). The remainder of the interaction between patient and provider will not be affected in any other way. The physician is free to make any recommendations based on their best judgment, and the patient is free to choose based on their preferences. The visit with the patient will be voice recorded and (immediately after the completion of the encounter) will be scored based on the OPTION score, which assesses patient participation in the shared decision making process.
