We applied a retrospective, non-interventional, cohort study design. The electronic medical
record database of the University hospital Heidelberg (ISH-med) was searched for patients
who underwent treatment at the Department of General Psychiatry in Heidelberg between 1st
January 2013 and 31st December 2013. The Department of General Psychiatry has 127 inpatient
beds as well as an outpatient department in a predominantly urban area in Heidelberg
and a fully integrated health service providing treatment for patients with all kinds of mental
disorders. The retrospective data were examined for daily in-patient costs, duration of treatment
and overall residential treatment costs.
