We aimed to study ED overcrowding across European centres.Methods Questionnaires on structure and process of care, including crowding, were distributed to 68 centres participating in a large European study on traumatic brain injury (Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury).Results Of the 65 centres included in the analysis, 32 (49%) indicated that overcrowding was a frequent problem and 28 (43%) reported that patients were placed in hallways ‘multiple times a day’; 27 (41%) stated that multiple times a day, there was no bed available when a patient needed to be admitted. Ambulance diversion rarely occurred in the participating centres.Conclusion Similar to reports from other parts of the world, ED crowding appears to be a considerable problem in Europe. More research is needed to determine effective ways to reduce overcrowding.
