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.
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.
Study Type
OBSERVATIONAL
Enrollment
161
All participants will undergo a muscle ultrasound on admission and at discharge
Complejo Hospitalario Universitario de Albacete
Albacete, Spain
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
Time frame: 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-).
Time frame: 15 days
Muscle mass (the anterior rectus femoris muscle)
The evolution of muscle mass between admission and discharge will be assessed by ultrasound
Time frame: 15 days
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.
Time frame: 72 hours
Hand grip strength
Using a hand-held dynamometer
Time frame: 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.
Time frame: 15 days

ADL (Activities of Daily Living) questionnaire
the ADL questionnaire will also be performed on admission, at discharge, and at 3 months.
Time frame: 3 months
SPPB score (SHORT PHYSICAL PERFORMANCE BATTERY score)
Short Physical Performance Battery (SPPB): score range 0-12, higher score means a better outcome
Time frame: 15 days
Mortality
Mortality will be measured with vital status at 3 months.
Time frame: 3 months
Length of stay, days

Readmission(s) after index hospitalization, Dichotomous outcome (yes/no)
Time frame: 3 months
Emergency department (ED) visit(s)
ED visit(s) after index hospitalization, Dichotomous outcome (yes/no)
