Standardized computer-based organized reporting of EEG: SCORE – Second version

Abstract

Standardized terminology for computer-based assessment and reporting of EEG has been previously developed in Europe. The International Federation of Clinical Neurophysiology established a taskforce in 2013 to develop this further, and to reach international consensus. This work resulted in the second, revised version of SCORE (Standardized Computer-based Organized Reporting of EEG), which is presented in this paper. The revised terminology was implemented in a software package (SCORE EEG), which was tested in clinical practice on 12,160 EEG recordings. Standardized terms implemented in SCORE are used to report the features of clinical relevance, extracted while assessing the EEGs. Selection of the terms is context sensitive: initial choices determine the subsequently presented sets of additional choices. This process automatically generates a report and feeds these features into a database. In the end, the diagnostic significance is scored, using a standardized list of terms. SCORE has specific modules for scoring seizures (including seizure semiology and ictal EEG patterns), neonatal recordings (including features specific for this age group), and for Critical Care EEG Terminology. SCORE is a useful clinical tool, with potential impact on clinical care, quality assurance, data-sharing, research and education.

Ictal and interictal electric source imaging in pre‐surgical evaluation: a prospective study

“…For localizing irritative zone and seizure onset zone (SOZ), the reference standard was the intracranial recording (ICR) using stereo-EEG. This was compared with the results of ESI (ECD and of DSM maxima) at sublobar level, as described elsewhere [21]. Full match at sublobar level was considered concordant and everything else was considered discordant.…”

“…Reporting of the frequency of epileptiform discharges may vary depending on the animal model used and the study protocol. We provide an option to record the frequency either as events per unit time (numerical value) or as a categorical grouping similar to what was proposed in the Standardized Computer‐based Organized Reporting (SCORE) system used for human EEG, that is, once (once); uncommon (<1/5 min); occasional (1/5–1/min); frequent (1/min–1/10 s); abundant (>1/10 s) . We acknowledge that the grouping of the frequencies of a discharge may differ across animal studies, since there are no uniform agreements on this issue for preclinical studies.…”

We therefore suggest that this categorization is optional and, when done, the investigators are prompted to define their specific grouping parameters in the methods (i.e., methods of an article, or upload in the scoring methods file in module 4).…”

“…[15,18]. Она включена в стандартную электронную систему формирования заключения ЭЭГ SCORE и переведена на русский язык [19]. Для создания баз данных, особенно при проведении кооперативных исследований, необходимо уточнение всех потенциально возможных параметров, однако в клинической практике следует указывать лишь оба основных термина, а их модификаторы использовать, исходя из принципа разумной достаточности.…”
