|Official Title:||Effectiveness of a Programme of Exercise on Physical Function in Survivors of Critical Illness Following Discharge From the Intensive Care Unit (ICU): a Randomised Controlled Trial|
- Physical Functioning subscale of the SF-36 [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]The primary outcome measure will be physical function as measured by the physical functioning (PF) subscale of the SF-36v2 following the exercise programme. This is an important outcome that is meaningful to patients. This has been shown to be an acceptable, reliable and valid tool following critical illness.
- Physical Functioning Subscale of the SF-36 [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Rivermead Mobility Index [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Physical Function will also be measured using the Rivermead Mobility Index.
- Hand Dynamometry [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Patients have indicated to us that hand function is particularly slow to return after critical illness and that this is important to them. Strength and dexterity will specifically be measured by dynamometry and the Nine Hole Peg Test.
- The Nine Hole Peg Test [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Patients have indicated to us that hand function is particularly slow to return after critical illness and that this is important to them. Strength and dexterity will specifically be measured by dynamometry and the Nine Hole Peg Test.
- Incremental Shuttle Walk Test [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Exercise capacity will be measured with the Incremental Shuttle Walk Test (ISWT). This is a valid and standardised test of exercise capacity which is responsive to exercise based interventions in other populations. Furthermore the ISWT was used in our pilot study and demonstrated the feasibility and responsiveness of this measure.
- Functional Limitations Profile [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Health related quality of life (HRQoL) will also be measured using Functional Limitations Profile (FLP) questionnaire. The FLP questionnaire is a well validated and widely used generic instrument to measure health status in a variety of conditions including critical illness. It provides an estimate of sickness related dysfunction and has both physical and psychosocial dimensions. It was used in our pilot study.
- other subscales of the SF-36 [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Health Related Quality of Life (HRQoL) is also assessed using other subscales of the SF-36v2, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. Scores are provided for each of these health domains, and two summary measures of physical and mental health: the Physical Component Summary (PCS) and Mental Component Summary (MCS).
- Hospital Anxiety and Depression Scale [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Anxiety and depression function will be measured using the Hospital Anxiety and Depression Scale (HADS). The HADS contains 14 statements and scores from 0-21. Scores of 8-10 indicate the possibility of anxiety or depression, and 11 and above indicate that these are likely to be present. It has been validated in the critical care population.
- 'Readiness to change' questionnaire [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Patient's readiness to exercise and self efficacy to exercise are important aspects of feasibility when commencing an exercise programme. Readiness to commence exercise following critical illness will be obtained by assessing components relating to the transtheoretical model (stages, processes, decisional balance, self-efficacy). There is evidence of reliability and validity of the questionnaires designed to measure these constructs.
- Chronic Disease Self Efficacy Scale (Exercise component) [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]The exercise component of the Chronic Disease Self Efficacy Scale will be used to measure self efficacy relating to exercise.
- The EuroQol-5D [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]The EuroQol-5D is a useful measure of health related quality of life in a mixed critical care population.
- Medical Research Council Dyspnoea Scale [ Time Frame: 6 weeks, 6 months ] [ Designated as safety issue: No ]Breathlessness will be measured by the Medical Research Council dyspnoea scale. Breathlessness is a common problem encountered by these patients and an important patient focused outcome.
- 'Healthcare Utilisation' Questionnaire [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Semi-structured Interview [ Time Frame: 6 months ] [ Designated as safety issue: No ]Patient's perceptions of the exercise programme will be explored.

|Experimental: Exercise programme||
Other: Exercise Programme
Patients will complete three exercise sessions per week (2 supervised and 1 unsupervised) for 6 weeks. They will receive a written exercise manual which facilitates completion of their exercise programme. The exercise programme will consist of a warm-up, an exercise circuit, a period of aerobic exercise, and a cool down. The programme will be tailored to each patient's ability and needs.
At the end of the 6 weeks patients will receive a short consultation to set goals relating to continuing exercise at home.
Other: Standard Care
Following ICU admission patients are discharged to hospital wards to the care of a consultant, and the patients are no longer under the care of the ICU team. They are provided with appropriate medical and nursing care, and with referral to other disciplines as necessary. One mobile and able to return home to a carer or another facility they are discharged from hospital. There is usually no support to address potential problems specific to critical illness for patients after ICU discharge.
Most critically ill adult patients require ventilatory support during their intensive care unit stay. Following discharge home patients often still suffer from reduced physical function, exercise capacity, health related quality of life and social functioning for at least 2 years. There is usually no support to address these longer term problems specific to critical illness for patients after hospital discharge. Little research has been carried out into interventions which could improve physical function and quality of life, or enhance speed of recovery in these patients. While there is evidence to support the rehabilitation of critically ill patients within intensive care units, there is a paucity of literature to support rehabilitation following discharge from intensive care and hospital. Therefore, there is a clear and urgent need to investigate interventions which could improve the recovery of patients discharged home after intensive care. This is emerging as a prominent therapeutic objective for the future for this population.
This study will investigate whether a programme of exercise following discharge from hospital will improve outcome in patients following critical illness compared to standard care.
