Why the study?

Does physical activity in the first five days after cardiac surgery improve functional capacity and reduce hospital length of stay in adult patients?

Population

83 adult patients undergoing cardiac surgery

Design

Cohort

Follow-up

up to hospital discharge (mean 9 days)

Key result

Higher levels of physiotherapist-supervised physical activity in the first five days after cardiac surgery were significantly correlated with a reduced length of hospital stay (R = -0.70).

Overview

May encourage early supervised activity post-cardiac surgery; hypothesis-generating, requires RCTs before practice change.

Structured PICO

Does physical activity in the first five days after cardiac surgery improve functional capacity and reduce hospital length of stay in adult patients?

P
Population
83 adult patients (mean age 66 years, 30% female) undergoing cardiac surgery via median sternotomy, monitored for physical activity from postoperative day 1 to 5.
E
Exposure
Physiotherapist-supervised and independent physical activity monitored via bi-axial accelerometer and skin sensors from postoperative day 1 to 5 (POD1 to POD5)
O
Outcome
Step count and physical activity intensity (METs)surrogate

Main Result

Effect estimate: R = -0.70

p-value: p=<0.001

Higher levels of physiotherapist-supervised and independent physical activity in the first five days after cardiac surgery correlate with improved functional capacity and shorter hospital stays.

Limitations

  • SenseWear Pro 3 Armband may overestimate energy expenditure for walking activities ≥4 METs
  • Accuracy of step count data in cardiac surgery patients with reduced arm-swing has not been established
  • Treating physiotherapists were not blinded to physical activity data
  • Limited number of female patients precluded sex-specific regression analysis of their independent physical activity levels

Cite This Study

Mungovan et al. (2016) conducted an observational in Cardiac surgery (n=83). Physiotherapist-supervised and independent physical activity was evaluated on Correlation between overall physiotherapist-supervised step counts and length of stay in hospital (R = -0.70, p=<0.001). Higher levels of physiotherapist-supervised physical activity in the first five days after cardiac surgery were significantly correlated with a reduced length of hospital stay (R = -0.70).
