Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Twice daily, progressive mobilisation of up to 30 minutes each day, performed one on one with a physiotherpist until discharge from hospital, unless contraindicated. All participants (including the intervention and control groups) will receive standard care.

Initial assessment comprises a timed 10m walk test, and the Human actvity Profile questionnaire.
Intervention code [1] 257706 0
Rehabilitation
Comparator / control treatment
Standard care comprises individual education about physical activity for heart failure, with in-hospital and home exercise. All patients will receive standard care.
Control group
Active

Outcomes
Primary outcome [1] 259774 0
Safety and feasibility: measured by the number of adverse events recorded (episodes of haemodynamic instability), the number of times the participant did not meet the safety criteria so intervention could not be performed; and the number of heart failure patients included in the study compared to the number admitted, time taken and compliance of physio to perform the intervention
Timepoint [1] 259774 0
Daily during the intervention
Primary outcome [2] 259775 0
Walking capacity measured by the best distance covered in two six minute walk tests conducted consecutively with 15 minutes rest
Timepoint [2] 259775 0
Day of discharge
Primary outcome [3] 259776 0
Return to activities of daily living measured by the 'Human Activity Profile' questionnaire
Timepoint [3] 259776 0
At initial assesment, day of discharge and within 2-4 weeks of discharge
Secondary outcome [1] 268547 0
Activity levels both immediately prior to and following discharge from hospital using sensewear armbands and Duke Activity Status Index (DASI) questionnaire
Timepoint [1] 268547 0
The week prior to and the week following discharge from hospital

The DASI will be measured at initial assesment, on the day of discharge and at 2-4 weeks following discharge from hospital
Secondary outcome [2] 268548 0
Walking speed measured by the 10m walk test
Timepoint [2] 268548 0
At initial assessment and discharge
Secondary outcome [3] 268549 0
Quality of life measured by the Minnesota Living with Heart Failure questionnaire
Timepoint [3] 268549 0
Day of discharge and within 2-4 weeks of discharge
Secondary outcome [4] 268550 0
Hospital length of stay measured by the number of days spent in hospital from admission to discharge taken from medical records.
Timepoint [4] 268550 0
Measured from admission to discharge from hospital
Secondary outcome [5] 268551 0
Readmission to hospital measured over a 12 month period following the intervention as taken from medical records
Timepoint [5] 268551 0
Monitored over a 12 month period

Eligibility
Key inclusion criteria
Patients admitted to hospital with
1. A primary diagnosis of ‘acute heart failure’, ‘heart failure’ or ‘exacerbation of heart failure’ or 'congestive cardiac failure' as diagnosed and documented by their treating physician.
2. Have been started on medical therapy for heart failure
3. Satisfy safety criteria (detailed below)
4. Provide signed written informed consent
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria:
New York Heart Association Classification: IV (shortness of breath at rest)
Terminally ill
Poor cognition or reduced ability for self care as deemed by treating medical team
Orthopaedic or other limitations that prevent mobility
Awaiting therapeutic cardiovascular procedure or hospitalisation for surgery
Presence of heart failure secondary to significant uncorrected primary valvular disease (except for mitral regurgitation secondary to LV dysfunction), new onset atrial fibrillation, anaemia
Obstructive and restrictive cardiomyopathies (diastolic heart failure)
Pacemakers which do not permit adequate heart rate response to exercise
Inability or refusal to sign informed consent

Safety criteria
Participants will not undergo mobilisation if they:
Are haemodynamically unstable
Show signs of recent heart attack including such as new/recurrent chest pain in the past 8 hours, rising troponin levels
Show new signs of uncompensated heart failure (such as dyspnoea at rest)
Show signs of heart electrical conduction problems (e.g. 3rd-degree AV block)
Have uncontrolled irregular heart rhythms (e.g. recurrent ventricular tachycardia or ventricular fibrillation, fast heart rate >110 beats per minute)
Have a resting systolic blood pressure >200mmHg or resting diastolic blood pressure of >110mmHg
Have a resting systolic blood pressure of <90mmHg patient will be reviewed by the medical team prior to mobilisation
Have poorly controlled symptomatic postural or low blood pressure (drop of >20mmHg with symptoms)
Resting oxygen saturation: <92%
Clinical judgement by the exercise specialist that patient clinical presentation is such that it would preclude safe mobility

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Initial contact will be made with potential participants on the ward. Participants will be screened against the inclusion and exclusion criteria. All participants will have medical clearance to be involved in this study. An information sheet will be provided to participants, and an opportunity to have all their questions answered by a member of the investigative team. Informed consent will be signed. Following the initial blinded assessment, patient allocation to the intervention and usual care groups will be undertaken via randomisation using a computer generated program by a person not involved in the recruitment and assessment of the participants. Participant allocation will be concealed using closed envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Following the initial blinded assessment, patient allocation to the intervention and usual care groups will be undertaken via randomisation using a computer generated program by a person not involved in the recruitment and assessment of the participants. To ensure approximate equal numbers in each group, a permuted block randomisation will be used.
Masking / blinding
