Admission type (1): urgent surgery vs elective surgery = reference.

Admission type (2): medical vs elective surgery = reference.

APACHE = acute physiology and chronic health evaluation score; CI = confidence interval; GH = Gelre Hospital, one of the participating hospitals; OLVG = Onze Lieve Vrouwe Gasthuis, one of the participating hospitals; OR = odds ratio; RDGG = Reinier de Graaf Groep, one of the participating hospitals.
