Kempenhaeghe is an expertise centre for epileptology, sleep medicine, and neurocognition. Doctors gather information about epilepsy patients in order to respond with adequate surgery and/or medication. Per patient, all data on symptoms, treatments, events and notes are stored in an information system in the form of a record that is known as an Electronic Health Record (EHR). These records ease the monitoring of theprogress of the patient over time. Since the records are stored textually, however, both the effectiveness and efficiency of the process of gathering deep(er) insight leave much room for improvement. This holds for a doctor working with the EHR of a patient and also for a clinical researcher studying the EHR data of cohorts of patients.

For Kempenhaeghe we propose a modernized version of their Electronic Health Records system that harnesses the power of interactive visualization to improve the clinical interaction. On the clinical side, it offers a flexible method for specifying a cohort of patients that can also be explored using interactive visual techniques, aiding the researchers at Kempenhaeghe with their studies. Finally, a bridge is proposed and partly implemented between these two modes of operandi of the system, to the benefit of both.
