In order to estimate the financial burden of ADEs in Germany, Stark et al (2011) based the cost study on a model originating from the American healthcare system. Their estimations quantified health care costs related to ADEs emerging from ambulator)’ care settings to a total of €816 million, or 0.22% of German health expenditure in 2011. Almost 60% was due to hospitalisations, 11% to emergency department visits and the remaining 21% from expenditures made in long-term care. However, these costs are only approximations.
