Abstract
Background: We explored the feasibility of linking research datasets to electronic health records to identify acute stroke computed tomography (CT) brain features associated with post-stroke dementia.
Methods: We linked data from two existing research datasets of people who had a stroke. These datasets contained expert-coded features from CT brain scans. Participants were followed up by linking to their electronic health records. Survival analyses were performed to identify prognostic factors associated with increased risk of post-stroke dementia.
Results: Twenty-one participants (11%, n = 21/185) were identified as having dementia after stroke (median follow-up: 9 years and 8 months). Presence of cerebral atrophy and moderate-to-severe white matter hyperintensities on acute stroke CT scans were associated with an increased risk of post-stroke dementia.
Conclusion: Linkage to electronic health records is a feasible method for studying dementia outcomes after stroke. This method can be applied to larger stroke populations to explore acute stroke imaging predictors in more detail.
期刊介绍:
The Journal of the Royal College of Physicians of Edinburgh (JRCPE) is the College’s quarterly, peer-reviewed journal, with an international circulation of 8,000. It has three main emphases – clinical medicine, education and medical history. The online JRCPE provides full access to the contents of the print journal and has a number of additional features including advance online publication of recently accepted papers, an online archive, online-only papers, online symposia abstracts, and a series of topic-specific supplements, primarily based on the College’s consensus conferences.
