  1. aDelirium status defined by CAM. CAM was missing in four patients from the orthopedic ward; bpreoperative delirium status unknown in nine patients from the acute geriatric ward and in 23 patients from the orthopedic ward; chighest MDAS in patients with delirium. MDAS was missing in four patients in the acute geriatric ward and in eight patients from the orthopedic ward; dnumber of days from first to last positive CAM; etime from admission to start of anesthesia. Three patients from the orthopedic ward did not undergo surgery; fmissing in two patients from the acute geriatric ward and in 17 patients from the orthopedic ward; gmasured with activPAL™ in 22 patients from the acute geriatric ward and in 24 patients from the orthopedic ward.
