Objective
Assess the Five Times Sit-to-Stand Test safety and clinimetric properties in
older patients hospitalized in an intensive care unit.
Methods
Test safety was assessed according to the incidence of adverse events and
through hemodynamic and respiratory data. Additionally, reliability
properties were investigated using the intraclass correlation coefficients,
standard error of measurement, standard error percentage change,
Altman-Bland plot and a survival agreement plot.
Results
The overall suitability of the Five Times Sit-to-Stand Test was found to be
low, with 29.8% meeting the inclusion criteria. Only 44% of the hospitalized
patients who met the inclusion criteria performed the test, with no need for
discontinuation in any patient. Heart rate (79.7 ± 10.2bpm/86.6
± 9.7bpm; p = 0.001) and systolic blood pressure (118 ±
21.4mmHg/129 ± 21.5mmHg; p = 0.031) were the only variables that
presented a significant statistical increase, with no evidence of
exacerbated response to the test. Additionally, no adverse events were
reported from participating and both test-retest and interrater reliability
were high (intraclass correlation coefficient ≥ 0.99).
Conclusion
The Five Times Sit-to-Stand Test was proven to be safe and to have excellent
reliability. Its clinical use, however, may be restricted to
high-functioning older adults in hospital settings.
