European data, mostly from European Union Member States, consistently show that medical errors and health care related adverse events occur in 8-12% of hospitalization. For example, the United Kingdom Department of health, in its 2000 report "An organisation with a memory", estimated about 850 000 adverse events a year (10% of hospital admissions). Spain (in its 2005 national study of adverse events) and France and Denmark have published incidence studies with similar results.
