Understanding Acute Sarcopenia

Not Applicable
Conditions
Sarcopenia
Interventions
Procedure: Colorectal surgery procedure
Procedure: Emergency abdominal surgery
Drug: Antibiotics
Registration Number
NCT03858192
Lead Sponsor
University of Birmingham
Brief Summary

This study aims to characterise acute changes in muscle mass, strength, physical performance in hospitalised older adults. We will assess the impact of these changes upon physical function at three month follow-up, and assess for the impact of clinical and immune-endocrine factors upon these changes.

Detailed Description

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?

GroupInterventionDescription
Elective colorectal surgeryColorectal surgery procedurePatients who are expected to undergo a major colorectal surgery procedure will be recruited to this study preoperatively and followed-up until three months postoperatively.
Emergency abdominal surgeryEmergency abdominal surgeryPatients 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.
Medical patientsAntibioticsPatients 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
Primary Outcome Measures
NameTimeMethod
Physical functionThree 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.
