Serial quality of life assessment around screening for familial intracranial aneurysms: a prospective cohort study.

INTRODUCTION: Screening for intracranial aneurysms (IAs) is cost-effective in first-degree relatives of aneurysmal subarachnoid haemorrhage (aSAH) patients, but its psychosocial impact is largely unknown. PATIENTS AND METHODS: A consecutive series of persons aged 20-70 years visiting the University Medical Centre Utrecht for first screening for familial IA was approached between 2017-2020. E-questionnaires were administered at six time points, consisting of the EQ-5D for health-related quality of life (QoL), HADS for emotional functioning and USER-P for social participation. QoL outcomes were compared with the general population, and between participants with a positive and negative screening for IA. Predictors of QoL outcomes were assessed with linear mixed effects models. RESULTS: 105 participants from 75 families were included; in 10 (10%) an IA was found. During the first year after screening we found no negative effect on QoL, except for a temporary decrease in QoL six months after screening in participants with a positive screen (EQ-5D -11.3 [95%CI:-21.7 to -0.8]). Factors associated with worse QoL were psychiatric disease (EQ-5D -10.3 [95%CI:-15.1 to -5.6]), physical complaints affecting mood (EQ-5D -8.1 [95%CI:-11.7 to -4.4]), and a passive coping style (EQ-5D decrease per point increase on the Utrecht Coping List -1.1 [95%CI:-1.5 to -0.6]). DISCUSSION AND CONCLUSION: We did not find a lasting negative effect on QoL during the first year after screening for familial IA. Predictors for a worse QoL were psychiatric disease, physical complaints affecting mood, and a passive coping style. This information can be used in counselling about familial IA screening.
