Overview

Supports device activity for frailty screening in CIED patients; leaves open prospective validation before clinical adoption.

Study Design

Type

Observational (n=219)

Structured PICO

Does device-detected physical activity correlate with frailty and mobility in outpatients with cardiac implantable electrical devices?

P
Population
219 outpatients with cardiac implantable electrical devices compatible with physical activity analysis with at least 7 days of data
I
Intervention
Device-detected physical activity measurement
O
Outcome
Association between device-detected physical activity and frailty (Study of Osteoporotic Fractures instrument) and mobility (gait speed, Timed Up and Go test)surrogate

Main Result

Effect estimate: OR 0.71 (95% CI 0.51-0.99)

Device-detected physical activity from cardiac implantable electrical devices correlates significantly with clinical frailty and mobility limitations, offering a potential automated tool for frailty assessment.

Cite This Study

Kramer et al. (2017) conducted an observational in Cardiac implantable electrical devices (n=219). Device-detected physical activity was evaluated on Frailty phenotype (OR 0.71, 95% CI 0.51-0.99). Each 1-hour increase in device-detected daily physical activity was associated with a reduced adjusted odds of frailty (OR 0.71; 95% CI 0.51-0.99) in patients with cardiac implantable devices.
