[Registries of in-hospital cardiac arrest are a challenge in daily clinical practice].

In-hospital cardiac arrest carries a poor prognosis. Registries of in-hospital cardiac arrest provide the opportunity to improve quality of care and conduct research of disease mechanisms and treatment. This paper describes the preliminary experience with systematic registration of in-hospital cardiac arrest at Aarhus University Hospital, Denmark. Data from 102 patients are presented and practical aspects and challenges of establishing a registry and implementing the collection of data in daily clinical practice are discussed.
