The purpose of the study is to investigate whether an extended program (ERAS 3.0) initiated hospital discharge, can improve recovery in elderly, frail patients who have undergone surgery for colon cancer. The study is a randomised controlled trial with two groups: an intervention group receiving the ERAS 3.0 program and a control group recieving standard care. The ERAS 3.0 program includes a comprehensive geriatric health assessment, dietary counseling from a dietitian, and instructions on training and physical activity. These activities will take place in the participant's homes after hospital discharge. Data will be collected at multiple time points: at the hospital, 12 days post-discharge (at the outpatient clinic), and at 1 and 3 months post discharge in the participants' homes.
