Sarcopenia Measured by Ultrasound in Hospitalized Older Adults

Study Overview
=================
Brief Summary
-----------------
Observational prospective study in older adults admitted to an Acute Geriatric Unit, in which sarcopenia will be evaluated by ultrasound in the anterior rectus femoris muscle.

Detailed Description
-----------------
The main objective of the study is to estimate, by means of portable ultrasound, parameters of muscle quantity and quality (anterior rectus femoris muscle area, width and echostructure ) in older adults hospitalized in Acute Geriatric Units for medical reasons.

Official Title

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Prevalence of sarcopenia on admission | Prevalence of sarcopenia on admission. A prevalent case of sarcopenia will be considered if a patient fulfills the EWGSOP2 at admission | 72 hours | 
| Incidence of sarcopenia between admission and discharge | An incident case of sarcopenia will be considered if a patient not fulfilling EWGSOP2 diagnostic criteria on admission, will meet diagnostic criteria at discharge of sarcopenia at discharge (diagnosis will be considered as a dichotomous variable -yes/no-). | 15 days | 
| Muscle mass (the anterior rectus femoris muscle) | The evolution of muscle mass between admission and discharge will be assessed by ultrasound | 15 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Minimal nutritional assessment (MNA-SF) score | The mini-nutritional assessment - short form is a simple, non - invasive and validated scale for the detection of malnutrition in older adults. It takes into account the patient's loss of appetite, weight loss, motor skills, recent health status, neuropsychological disorders. The maximum score of the MNA-SF is 14: Greater than or equal to 11: normal nutritional status. Between 8 and 11: risk of malnutrition. Less than 8: malnutrition. | 72 hours | 
| Hand grip strength | Using a hand-held dynamometer | 15 days | 
| 4-meter walking speed test | The evolution of the value of the 4-meter walking speed test between admission and discharge will be assessed. | 15 days | 
| ADL (Activities of Daily Living) questionnaire | the ADL questionnaire will also be performed on admission, at discharge, and at 3 months. | 3 months | 
| SPPB score (SHORT PHYSICAL PERFORMANCE BATTERY score) | Short Physical Performance Battery (SPPB): score range 0-12, higher score means a better outcome | 15 days | 
| Mortality | Mortality will be measured with vital status at 3 months. | 3 months | 
| Length of stay, days | Day of admission to day of discharge | 15 days | 
| Readmission(s) after index hospitalization | Readmission(s) after index hospitalization, Dichotomous outcome (yes/no) | 3 months | 
| Emergency department (ED) visit(s) | ED visit(s) after index hospitalization, Dichotomous outcome (yes/no) | 3 months |
