| The effect of exercise on patient fitness and quality of life after intensive care admission |
| ISRCTN | ISRCTN65176374 |
| ClinicalTrials.gov identifier | |
| Public title | The effect of exercise on patient fitness and quality of life after intensive care admission |
| Scientific title | The impact of an aerobic exercise rehabilitation programme on fitness and quality of life in intensive care unit survivors: an exploratory trial |
| Acronym | N/A |
| Serial number at source | 2008010 |
| Study hypothesis | To evaluate the effect of an 8-week supervised exercise programme on patient fitness (as judged by AT [anaerobic threshold] measurement) and quality of life (as judged by 36-item short form health survey [SF-36] and Euroqol EQ-5D), following critical illness and discharge from intensive care unit (ICU). |
| Lay summary | |
| Ethics approval | Ethics approval received from the Newcastle and North Tyneside 1 Research Ethics Committee on the 16th January 2008 (ref: 07/H0906/137) |
| Study design | Multi-centre, parallel group randomised controlled trial |
| Countries of recruitment | United Kingdom |
| Disease/condition/study domain | Quality of life after ICU admission |

| Interventions |
Eligible patients will be asked to attend for a baseline AT measurement and QoL questionnaires 8 - 16 weeks post-discharge from hospital. Patients will be then be randomised into intervention or control groups. The 'usual care' group will be the control.
We have elected to adapt the process of simple random allocation of subjects to groups by using a minimisation method. Minimisation will be performed using Minim software. Initially, a permuted block design (1:1 ratio) will be employed with block sizes of 2, 4, and 6 selected at random. Thereafter, minimisation will be incorporated to ensure a good balance between trial arms. We intend to minimise on three factors; age (18 - 39 years versus 40 - 65 years), sex (male versus female), and diagnosis on entry to ICU (sepsis versus trauma). The allocation sequence will be generated and held by a statistician who is not involved in enrolment or assessment of outcomes, and will be concealed from the investigators until baseline AT has been measured and baseline questionnaires completed. The patients in the intervention group will be required to perform a 40 minute exercise session, twice a week for 8 weeks under supervision by trained staff with resuscitation equipment available. and one unsupervised session per week (brisk 40 minute walk). All exercise sessions will be of appropriate intensity and duration to provide a sufficient exercise challenge to test our hypothesis. All patients will be asked to return at week 9 to retest their AT measurement as well as complete the four questionnaires. This will also be repeated at week 26 of the study for both arms. Patients allocated to the control groups will be seen at weeks 0, 9 and 26 for AT measurement and completion of questionnaires. |
| Primary outcome measure(s) |
Changes in AT and quality of life (QoL). QoL will be measured using the SF-36 (Version 2) and EQ-5D questionnaires.
The primary outcome will be assessed in intervention and control groups at baseline, week 9 (post 8-week intervention period), and at 26 weeks. The primary comparison is the change in AT and QoL scores from baseline to week 9 (post 8 week exercise program). |
| Secondary outcome measure(s) |
Secondary outcome analysis will include:
1. Time of return to work 2. Assessment of mental health (Hospital Anxiety and Depression Scale [HADS] questionnaire) 3. Habitual physical activity outside of (and following) the intervention period. Habitual physical activity will be monitored using a validated self-report instrument. This will be completed after enrolment at baseline, week 9, and at 26 weeks, providing exploratory data for the association between the exercise training and physical activity levels. Other data collection: In addition to the outcome measures above the following data will be collected: 4. Demographic data - age, sex, reason for ICU admission 5. Duration of ICU and hospital stay 6. Medication 7. Time of study enrolment 8. Premorbid quality of life analysis - we accept that this element may be subject to patient recall bias with subjects forgetting their "true" premorbid QoL. Accurate recall may be affected by the ICU experience leading to "over-estimation" of premorbid QoL. |
