Design: Prospective, population based cohort study. Setting: Primary and secondary care throughout Scotland. Participants: 187 adults (aged ≥16 years) resident in Scotland at the time of their first diagnosis of a brain arteriovenous malformation in 19992002. Intervention: Postal consent form sent via participantsgeneral practitioner. Main outcome measures: Differences between consenters and nonconsenters in demographic and clinical features at first presentation, and outcome during followup. Results: 111 adults (59%) consented to participate in the study. These consenters were not significantly different from nonconsenters in age, sex, or socioeconomic status at first presentation. However, consenters were significantly more likely than nonconsenters to present alive and independent, and with a seizure. During followup, consenters were significantly more likely to receive interventional treatment. Although consenterssurvival was significantly better, they were more likely to have a seizure during followup. Presentation with intracranial haemorrhage conferred a higher risk of subsequent haemorrhage when the whole cohort was analysed, but not when it was restricted to consenters. Conclusions: We have found differences between adults who consent to participate in observational recordsbased research and those who do not, or cannot, consent Blanket requirements for explicit consent for the use of individualsidentifiable data can bias disease registers, epidemiological studies, and health services research.展开更多
