ICU Survivor clinical trials

Effect of Sit-to-Stand Intervention in the Intensive Care Unit Survivors

"Sit-to-stand" is key to independent living. For intensive care unit (ICU) survivors, failure to perform sit-to-stand results in bed-bound status, unable participating in important activities of daily living (ADLs) or instrumental ADLs. Recent studies indicated that 31% of ICU survivors remained bed-bound and unable to "sit-to-stand" after returning home. Our preliminary findings further indicated that 70% of ICU survivors who had the ICU-acquired weakness (ICU-AW) were unable to "sit-to-stand" one-month after ICU discharge. The aim of this 3-year research project was to develop a feasible and effective "sit-to-stand" care (STS Care). A randomized controlled trial (RCT) design is proposed to examine effects of the STS Care in improving ICU patients' "sit-to-stand" ability, physical function, and rates of bed-bound and mortality one year following ICU discharge. The trial was approved by the Human Research Ethics Committee at the study site before enrollment. Adult ICU patients (≥ 20 years) admitted consecutively to six medical ICUs of a university affiliated medical center was eligible for the study if they were unable to "sit-to-stand" independently at ICU discharge. Upon signing informed consent, participants will be first stratified by "able to remain sitting upright without falling" or "unable to remain sitting upright" and then randomized separately into the intervention or usual care groups, according to computer-generated randomization tables. Participants in the intervention group received both usual care and the STS Care. The hospital-based (up to 14 days) STS Care, which was provided daily by the same trained nurse, consisted of nurse-supervised anti-gravity and resistant exercise (intensity based on patients' tolerance), repetitive sit-to-stand practice, and advice on sit-to-stand strategies. A comprehensive functional evaluation (success rate of sit to stand, scores of FSS-ICU, scores of MRC muscle scale, muscle strength at knee extensors, scores of the barthel index for activities of daily living (ADL), scores of instrumental activities of daily living scale (IADL), the walking distance by the 6-minute walk test, numbers of sit-to-stand repetitions in 30 seconds, rate of bed-bound status, rate of mortality) was assessed by blinded research nurses after ICU discharge at 5 time points:48hours, 14 day, 1, 3, and 12 months.
