Examination of the effectiveness of DVD decision support tools for patients with unruptured cerebral aneurysms.
Preventative treatments for unruptured cerebral aneurysms include craniotomy, endovascular treatment, and follow up. Since there is no agreement as to the best procedure, it is important to provide adequate information so that the patient and physician can share in the decision-making process. A multi-media DVD was created to inform patients of the facts. This study examined how effectively this DVD changes patients' recognition including knowledge of unruptured cerebral aneurysms. Forty-seven patients with unruptured cerebral aneurysms who sought neurosurgery consultation between December 2005 and February 2006 completed a questionnaire before and after watching the DVD, as well as at 3 months follow up. Before watching the DVD, the average knowledge score was 8.72 out of 15 total points. The average score increased to 12.4 after watching the DVD (p < 0.001). At 3 months follow up, the average score was 10.34, which was still higher than before watching the DVD (p < 0.01). Participants' knowledge about treatment methods also increased after watching the DVD (p < 0.001). Compared to 63.2% who were satisfied with their treatment decision before watching the DVD, 69.6% were satisfied with their decision after watching the DVD. All participants responded that the use of multi-media images was helpful in better understanding treatment options and in making informed decisions. The DVD was favorably accepted as a decision support tool by patients with unruptured cerebral aneurysm and effectively increased patients' knowledge.
