Objective Quantification of In-Hospital Patient Mobilization after Cardiac Surgery Using Accelerometers: Selection, Use, and Analysis
Why the study?
Cardiac surgery patients infrequently mobilize during hospital stays, and exact progress of mobilization activities is not available.
Can accelerometers objectively quantify in-hospital mobilization after cardiac surgery?
Population
29 patients after cardiac surgery
Comparison
Triaxial accelerometer placement on upper arm and upper leg to classify postoperative mobilization activities
Design
Clinical pilot study

Implication
May enable objective tracking of postoperative mobilization; hypothesis-generating for outcome impact in cardiac surgery.
Structured PICO
Can accelerometers objectively quantify in-hospital mobilization after cardiac surgery?
P
Population
29 patients after cardiac surgery (22 men, 7 women)
I
Intervention
Triaxial accelerometer (AX3, Axivity) placed on both the upper arm and upper leg, using an artificial neural network algorithm to classify activities
O
Outcome
Daily amount of each activity performed between 7 a.m. and 11 p.m.surrogate
Triaxial accelerometers can successfully quantify and monitor the daily postoperative mobilization of cardiac surgery patients.
