Although the role of continuous EEG (cEEG) in ICU is well established, the variability of access to EEG in ICUs across the world is poorly documented. It is likely that variation in EEG availability between ICUs will contribute to variability in management practices and may impact significantly on the outcome of patients with seizures and acute neurological disturbances. In this study, we surveyed the level of EEG availability in ICUs in different parts of the world to better understand the practical context in which studies of EEG in ICU should be interpreted. A survey was formulated by a clinical neurophysiologist (JMcH), and two intensivists (LMacD and MH). This was distributed to intensivists using a Survey-Monkey link. The sample population was primarily identified by direct personal messaging to Twitter followers of European Society of Paediatric and Neonatal Intensive Care (ESPNIC) and European Society of Intensive Care Medicine (ESICM) who self-identified as ‘Intensivist’, ‘Consultant Intensivist’ and/or ‘ICU consultant’. This was augmented by direct contact with intensivists from European and other centres internationally. The questionnaire quantified access to EEG testing and specialist interpretation and included a site-identifying question to avoid inclusion of duplicate responses. CEEG was defined as recordings of > 3 h. Recordings of than 12 h and overnight recording. Frequency of Need for cEEG in Clinical Practice Intensivists were asked how often cEEG was indicated to answer clinical questions in their unit. There were 58 respondents to this question. Three units (5%) said that
