Condition or disease | Intervention/treatment | Phase |
---|---|---|
Sarcopenia | Procedure: Colorectal surgery procedure Procedure: Emergency abdominal surgery Drug: Antibiotics | Not Applicable |
Study Design
Time-limited cohort study involving serial measurements of Bilateral Anterior Thigh Thickness (BATT) using ultrasound, handgrip strength, physical performance, and physical function measured using the Patient Reported Outcome Measures Information System (PROMIS®). We aim to fully characterise changes in these patients, and will perform a comprehensive evaluation of clinical factors including nutrition and physical activity, and measure immune-endocrine markers of inflammation.
Study Participants
Elective colorectal surgery, emergency abdominal surgery, and medical patients aged 70 years and older
Planned Size of recruitment target
56 elective colorectal patients, 56 emergency abdominal surgery patients, and 56 medical patients with acute infections
Follow up duration
3 months
Primary research question
Does acute change in quadriceps muscle thickness, handgrip strength and/or physical performance within one week of hospitalisation predict change in patient reported physical function at three months?
Study Type : | Interventional (Clinical Trial) |

Arm | Intervention/treatment |
---|---|
Experimental: Elective colorectal surgery
Patients who are expected to undergo a major colorectal surgery procedure will be recruited to this study preoperatively and followed-up until three months postoperatively.
|
Procedure: Colorectal surgery procedure
Elective admission for colorectal surgery |
Experimental: Emergency abdominal surgery
Patients who are admitted as an emergency and undergo abdominal surgery will be recruited from general surgery wards either preoperatively or within 48 hours of surgery. They will be followed-up until three month postoperatively.
|
Procedure: Emergency abdominal surgery
Emergency admission necessitating emergency surgery |
Experimental: Medical patients
Patients admitted under general medicine with an infection will be recruited from general medicine wards within 48 hours of admission. They will be followed-up until three month post-admission
|
Drug: Antibiotics
Treatment for infection and reason for admission |
- Physical function [ Time Frame: Three months ]
Change in physical function at three months as measured by the T score derived from the Patient Reported Outcome Measures Information System (PROMIS®) - Item Bank v. 2.0, Physical Function, Short Form 10b.
This is a patient-reported outcome measure of physical function. Raw scores are collected out of a maximum of 50; minimum of 10. These are converted to T scores, which are used for analysis (mean 50, SD 10; range 13.8 - 61.3). Higher scores are representative of better physical function.
