Detaljert beskrivelse
Rationale: Despite numerous studies supporting adverse outcomes associated with low physical activity (PA), there is insufficient insight in the amount of PA of acutely hospitalized Dutch elderly ≥ 70 years. PA can be objectively measured by accelerometers, but it is time consuming and expensive to provide every patient with an accelerometer. We need to be able to predict which elderly patients are likely to spend low amounts of physical activity during hospitalization. Because of the association between PA and functional decline it is expected that functional assessment tests like the Short Physical Performance Battery (SPPB) or Activity Measure for Post-Acute Care (AM-PAC) could be used as a screening tool to determine which patients will be at risk of low amounts of PA.
Objective: The primary objectives of this study are: 1) To assess the amount of PA of acutely hospitalized elderly ≥70 years during hospitalization and to create reference values regarding the amount of time patients are standing and walking per day and the number of breaks in sedentary time (BST) per day. 2) To be able to predict the probability of low amounts of physical activity during hospitalization for acutely hospitalized elderly ≥70 years.
Study design: This is a single center, observational, prospective cohort study.
Study population: 165 patients aged ≥70 years that are acutely hospitalized at the department of internal and geriatric medicine in the Maastricht University Medical Center (MUMC+).
Method: PA will be monitored with an accelerometer from inclusion (t0) until the day of intended discharge (t1). A functional assessment (SPPB and AM-PAC) will be performed at t0. Medical and demographic data will be obtained from the medical record and by patient report.
Main study parameters/endpoints: Mean number of minutes spent physically active (standing and walking) per day, dichotomized into a low and high amount of time spent physically active per day during hospitalization for the prediction model. Mean number of BST per day, dichotomized into a low and high number of BST per day during hospitalization for the prediction model.

Tidsramme |
|---|---|---|
|
Mean number of minutes spent physically active (standing and walking) per day
Tidsramme: Measured continuously from the day of inclusion (Day 0) until the day the subject is medically ready to be discharged from the hospital.
|
Defined as the total number of minutes standing and walking divided by the total number of valid measurement days in the period between inclusion and (intended) discharge.
In order to create a prediction model, this will be dichotomized into a low and high amount of time spent physically active per day during hospitalization.
As the estimated event rate of a high amount of time spent physically active per day during hospitalization is 50%, the cut-off value between a low and high amount of time spent physically active will be defined by dividing the cohort at the median.
|
Measured continuously from the day of inclusion (Day 0) until the day the subject is medically ready to be discharged from the hospital.
|
|
Mean number of breaks in sedentary time (BST) per day
Tidsramme: Measured continuously from the day of inclusion (Day 0) until the day the subject is medically ready to be discharged from the hospital.
|
Defined as the total number of BST divided by the total number of valid measurement days in the period between inclusion and (intended) discharge. A BST is defined as any transition from being sedentary (lying or sitting) to being physically active (standing or walking). In order to create a prediction model, this will be dichotomized into a low and high number of breaks in sedentary time per day during hospitalization. As the estimated event rate of a high number of breaks in sedentary time per day during hospitalization is 50%, the cut-off value between a low and high number of breaks in sedentary time will be defined by dividing the cohort at the median. |

Short Physical Performance Battery scores (summary and component scores)
Tidsramme: Measured on the day of inclusion (Day 0)
|
Summary score on the scale: 0-12 points.
Higher scores indicates better functioning.
SPPB evaluates balance, gait, strength and endurance by examining an individual's ability to stand with feet together in side-by-side, semi-tandem and tandem positions, time to walk 4 meter and time to rise from a chair and return to the seated position five times.
Component scores (0-4) for the three categories are measured as well.

Activity Measure for Post-Acute Care (AM-PAC) Inpatient Basic Mobility short form score
Tidsramme: Measured on the day of inclusion (Day 0)
|
The AM-PAC and provides a transparent measure of patients' capabilities in functional mobility during hospitalization.
It measures the following daily activities: turning in bed, sitting down and standing up, moving from lying to sitting position, moving from a bed to a chair, walking and climbing stairs (6-24 points).
