Key result
Baseline 5-meter walk distance and walking distance test were associated with the length of hospital admission in patients undergoing open heart surgery.
Why the study?
It was unclear whether a fixed-duration walking test (6-MWT) or a fixed-distance walking test (5-MWD) predicts duration of hospital admission in patients undergoing open heart surgery.
Do the 5-MWD and 6-MWT predict the length of hospital admission in patients undergoing open heart surgery?
Cohort (n=57)
No
Do the 5-MWD and 6-MWT predict the length of hospital admission in patients undergoing open heart surgery?
The 5-meter walk distance test may serve as a practical alternative to the 6-minute walk test for predicting hospital length of stay in patients undergoing open heart surgery.
Answers are grounded in this paper and cite their sources.
May support preoperative risk stratification in cardiac surgery; leaves open whether walk tests should guide interventions.
Context: The 6-minute walk test (6-MWT) has been commonly used to assess patients after open heart surgery. However, due to some situations, where patients could not perform the test for the duration of 6-minutes, a short walking distance test has been utilized to test the patients (i.e., 5-meter walk distance: 5-MWD). However, little is known whether fixed duration walking test, or fixed-distance walking test, regarding to the prediction of duration of hospital admission. Aims: The aim of the study was to evaluate the 6-MWT and 5-MWD in patients who had undergone open heart surgery, in order to predict hospital admission. Settings and Design: A prospective cohort study was designed at Thammasat University Hospital, Thailand. Methods and Material: Fifty-seven participants, who had open heart surgery were recruited and were asked to perform 6-MWT and 5-MWD pre and post-operative heart operation. Statistical Analysis Used: Regression analysis was used to test the prediction of the length of hospital admission and the walking performance. Results: A regression analyses indicated that after adjustment for age and gender, baseline 5-MWD and 6-MWT were associated with increased the hospital admission (ΔR2 = 0.112 and ΔR2 = 0.068, respectively). Conclusions: The 5-MWD might be an alternative to predict the length of hospital admission in patients who had undergone open heart surgery.

Yuenyongchaiwat et al. (2019) conducted a cohort in open heart surgery (n=57). 5-meter walk distance (5-MWD) and 6-minute walk test (6-MWT) was evaluated on length of hospital admission (ΔR2 = 0.112 for 5-MWD and ΔR2 = 0.068 for 6-MWT). Baseline 5-meter walk distance and walking distance test were associated with the length of hospital admission in patients undergoing open heart surgery.
