Description of intervention(s) / exposure
This will be an observational study of older patients undergoing elective colorectal surgery.
Patients will be recruited at least two weeks and not more than six months prior to surgery.
Markers of frailty will be assessed preoperatively using three different measures.
1. An edmonton frailty scale score (EFS) will be recorded two weeks prior to scheduled surgery
2. Activity levels (using a step counter) will be measured for 10- 14 days prior to scheduled surgery.
3. A blood test assessing mitochondrial function which has been associated with ageing will be performed at two weeks prior to scheduled surgery.

Other than the assessment of these frailty markers, patients will undergo routine perioperative care.

Post operatively, patients will be followed for 100 days and observed for a number of outcomes (specified further in section 4)

EFS will be repeated on day 30 postoperatively
Mitochondrial function blood test will be repeated on day 2 and day 30 postoperatively
Activity levels will be measured from day 2 postoperatively for 14 - 28 days

Post operative complications.
- a standardised proforma has been designed for the study that includes surgical and medical complications. This data will be gathered prospectively during the inpatient postoperative stay combined with a review of medical records at 30 and 100 days.
Examples of complications on proforma include
SURGICAL COMPLICATIONS (graded clavien dindo I-V)
surgical site infection
anastomotic leak
return to theatre
CVS (arrest, MI, DVT/PE, arrhythmia requiring intervention)
Respiratory (pneumonia)
Neurological (CVA, acute delirium)
Renal (AKI, UTI, failed TOV)

Brief summary
Older patients who undergo surgery are more likely to have complications and prolonged recovery after their operation. One of the things which can predict recovery after surgery in older patients in frailty. Frailty results from age-related changes and affects people’s ability to tolerate medical treatments, including operations.
This is an observational study which will be looking at older people who are having colorectal surgery. We will measure the frailty of the participants using a frailty assessment tool. We will also measure their daily activity levels with a watch that counts steps, and the function of their mitochondria, which is the part of the cell that produces energy.
We will follow these people after their operation to see how well they recover. We aim to investigate the relationship between frailty, activity levels and the function of the mitochondria, and see if these things are associated with how well patients recover following an operation.
