aIncident delirium, (re-)admittance to hospital and admittance to institution were analyzed using logistic, LoS using Poisson and change in EQ-5D using linear regression multilevel models. All GLM analyses were adjusted for age, sex and baseline Activities of Daily Living (ADL) and for clustering and time effect
