- The electroencephalography (EEG) signal has a high complexity, and the process of extracting clinically relevant features is achieved by visual analysis of the recordings. The interobserver agreement in EEG interpretation is only moderate. This is partly due to the method of reporting the findings in free-text format. The purpose of our endeavor was to create a computer-based system for EEG assessment and reporting, where the physicians would construct the reports by choosing from predefined elements for each relevant EEG feature, as well as the clinical phenomena (for video-EEG recordings). A working group of EEG experts took part in consensus workshops in Dianalund, Denmark, in 2010 and 2011. The faculty was approved by the Commission on European Affairs of the International League Against Epilepsy (ILAE). The working group produced a consensus proposal that went through a pan-European review process, organized by the European Chapter of the International Federation of Clinical Neurophysiology. The Standardised Computer-based Organised Reporting of EEG (SCORE) software was constructed based on the terms and features of the consensus statement and it was tested in the clinical practice. The main elements of SCORE are the following: personal data of the patient, referral data, recording conditions, modulators, background activity, drowsiness and sleep, interictal findings, episodes (clinical or subclinical events), physiologic patterns, patterns of uncertain significance, artifacts, polygraphic channels, and diagnostic significance. The following specific aspects of the neonatal EEGs are scored: alertness, temporal organization, and spatial organization. For each EEG finding, relevant features are scored using predefined terms. Definitions are provided for all EEG terms and features. SCORE can potentially improve the quality of EEG assessment and reporting; it will help incorporate the results of computer-assisted analysis into the report, it will make possible the build-up of a multinational database, and it will help in training young neurophysiologists.

- Purpose: Status epilepticus (SE) has attracted renewed interest lately, and efforts are made to optimize every treatment stage. For refractory SE, optimal supporting care involves mechanical ventilation and intensive care unit (ICU) admission. Infections often complicate SE and recently a single-centre observational study demonstrated an association between infections and poor short-term outcome of SE in a cohort of severely ill patients. We have here attempted to replicate those findings in a different cohort. Method: We performed a retrospective observational study and included all patients with a diagnosis of SE during 2008-2012 at a Swedish tertiary referral centre. Results: The cohort consisted of 103 patients (53% female, 47% male, median age 62 years, range 19-87 years). In house mortality was less than 2 and 70% of the patients' were discharged home. The most common aetiologies of SE were uncontrolled epilepsy (37%) and brain tumours (16%). A total of 39 patients suffered infections during their stay. Presence of infection was associated with mechanical ventilation (OR 3.344, 95% Cl 1.44-7.79) as well as not being discharged home (OR2.705, 95% Cl 1.14-6.44), and duration of SE was significantly longer in patients with infection (median 1 day vs. 2.5 days, p < 0.001). Conclusion: We conclude that the previously described association between infections, a longer SE duration, and an unfavourable outcome of SE seems valid also in SE of less severe aetiology.
