University College, London4,309,481 enrolled

Overview

The trajectory of dementia patients within the national health system and their recent temporal trends remains to be fully elucidated. To study the dementia incidence, mortality and case-fatality, we implemented a longitudinal cohort study with the linked electronic health records of 5.6 million population in the UK from 1998 to 2016 (CALIBER). A matched case-control study design was used to investigate the causes of hospitalization and death comparing individuals with and without incident dementia.
