Abstract
To investigate the impact of a six-week supervised exercise programme on cardiopulmonary fitness, balance, muscle strength and anxiety and depression in patients who have been discharged home from hospital following an intensive care unit length of stay of greater than 48 h. To investigate patients' perceptions of a six-week supervised exercise programme delivered at three months post hospital discharge. A single centre parallel, randomised controlled trial. Outpatient department of a university teaching hospital in the UK. Sixty adult survivors of critical illness, at three months post-hospital discharge. A six-week individually prescribed and supervised exercise program, with associated advice to home exercise modification. Twice weekly exercise sessions were individualised to participant's functional status and included cardiopulmonary, balance and strengthening exercises. Follow up at seven weeks, six months and 12 months. Six-Minute Walk Test, BERG balance test, grip strength and Hospital Anxiety and Depression Scale. A pre-designed survey was used to explore patient perceptions of the programme. Sixty participants (n = 30 received allocated programme in both control and treatment groups) were randomised. Loss to follow up resulted in n = 34 participants for intention to treat analysis at 12 months follow up (leaving n = 19 in control group, n = 15 in treatment group). Median participant age at enrolment was 62 years (interquartile range: 49-72), with a median intensive care unit length of stay of nine days (interquartile range: 4-17). No significant differences were found for the Six-Minute Walk Test at any time point (p > 0.05). Anxiety levels and balance were significantly improved in the treatment group at 12 months (p = 0.006 and p = 0.040, respectively). Further research is needed into appropriate interventions and outcome measures, target patient populations and timing of such intervention post-hospital discharge.
