Abstract
IIntroduction: Sedentary behavior (SB) and physical activity (PA) are
modifiable independent risk factors for morbidity and mortality. Physical
function in ICU survivors is often poor, yet objective descriptions of SB/PA
patterns and in-hospital tracking over a hospitalisation are lacking.
Objectives: To describe changes in SB/PA over 24-hour periods at awakening(
T1), ICU discharge(T2) and hospital discharge(T3).
Methods: A prospective observational study in a tertiary center of
consecutive adults who required _5 days of mechanical ventilation. Data
collected at T1/T2/T3 included: monitoring of body posture (SB) with the
thigh-worn ActivPAL and PA (intensity) with the wrist-worn GENEActiv.
SB/PA data were reported as time (percent-of-day) spent sitting/lying,
upright, at intensity cut-points, and in PA bouts. Breaks from SB (sit-tostand
transitions) were also reported. Statistical analysis from T1-T3 was
by repeated measures analysis of variance.
Results: 40 participants with mean(SD) age 62(15) years were recruited at
T1. The mean(SD) time spent sitting/lying was 99.6%(0.9%) at T1(n ¼ 40),
99.0%(1.2%) at T2(n ¼ 38) and 96.7%(3.0%) at T3(n ¼ 23) (mean[95% confidence
interval] decrease T1eT3 ¼ -3.0%[-4.6% to -1.4%], p_0.001). Time
spent upright was 0.4%(0.9%) at T1(n ¼ 40), 1.0% (1.2%) at T2(n¼38) and
3.3%(3.0%) at T3(n ¼ 23) (mean[95% CI] increase T1eT3 ¼ 3.0%[1.4% to
4.6%], p_0.001). Time spent at ‘inactive’ intensities (<200g.min) decreased
overall (p _ 0.018), but only over ICU admission (T1-T2) and not on the
wards (T2eT3). Time spent upright in _2 and _5 minute bouts did not
change in ICU (T1-T2), only increasing on theward (T2eT3, p_0.05). Sit-tostand
transitions increased from T1eT3 (mean[95% CI] T1-T3 ¼17.7[10.8 to
27.7], p _ 0.001).
Conclusion(s): ICU survivors’ decreased time spent lying/sitting and
increased time spent upright over admission. PA bouts, SB breaks and PA
intensity data showed how time was spent and when (ICU or ward)
changes occurred that could be used to inform a SB intervention.

Other | The ANZICS/ACCCN Intensive Care Annual Scientific Meeting is regarded as the flagship event for the Society. The ASM is one of the largest Intensive Care Conferences in the Southern Hemisphere, with over 1000 delegates attending each meeting. This year the event returns to Adelaide, South Australia from the 11th – 13th October 2018. The meeting is multidisciplinary and has a robust Scientific Program that is suited to all Critical Care Clinicians. |
