Assessing Frailty and Its Impacts on Patients Facing Major GI Surgery

"All participants will be asked to complete baseline assessments and a blood test.~30 participants out of the 100 will be selected to wear a digital motion device before their surgery for seven days. (15 participants will be non-frail and 15 patients will be frail).~Where possible, all baseline assessments will be scheduled to coincide with a routine clinic/hospital visit. The first assessment will complete functional, frailty, nutritional, and quality of life questionnaires. A blood test will be taken for baseline tests and metabolomic assessment. Participants who opt into having a digital motion device will also be shown how to use the device and will wear this for seven days. Written instructions to fit the device will also be given."
