Abstract:

Mary Elizabeth’s Hospital, a new hospital for children, adolescents, and expecting families, will open at Rigshospitalet in 2027. This thesis considers practical and methodological challenges in determining the causal effect of this new hospital using data from the nationwide Danish registers. The situation before the opening is studied in a descriptive overview of pediatric contacts at the Danish tertiary hospitals during 2000-2018, and by developing statistical methods for fair hospital comparisons using recurrent event outcomes (such as repeated outpatient visits). The thesis also estimates the effect of the first Danish children’s hospital, the Hans Christian Andersen Children’s Hospital at Odense University Hospital, on hospital-level activity outcomes using synthetic control methods and on patient-level health outcomes using three different approaches.
