RESTORE-TAVI Pilot
Study Details
Study Description
Brief Summary
This pilot randomised control study will investigate the feasibility and efficacy of a perioperative multi-component frailty intervention in patients with acute decompensated aortic stenosis undergoing urgent transcatheter aortic valve implantation compared to standard care. The intervention will consist of physical rehabilitation, cognitive stimulation/delirium avoidance strategies, nutritional supplementation and anaemia correction (where indicated). The primary outcome is to determine the feasibility and safety of delivering this intervention and to investigate the impact on health-related quality of life. Secondary outcomes include changes in functional status, frailty, readmission rates and mortality.

Outcome Measures
Primary Outcome Measures
- Feasibility: Recruitment rates [12 months]
Average number of patients per month willing to give informed consent and be randomised into a trial of a perioperative frailty intervention
- Feasibility: Acceptability and uptake [Inpatient admission]
Assessed using a patient-reported questionnaire on discharge from tertiary centre
- Feasibility: Attrition rates [90 days]
Proportion of patients who provided outcomes and 30 day and 90 day follow-up
- Feasibility: Safety [Daily (during inpatient admission)]
In-hospital adverse events (e.g. falls, ischaemia, arrhythmia, acute kidney injury), in-hospital mortality
- Health-related quality of life [90 days]
Measured using the self-reported EQ-5D-5L scale at 30 days and 90 days post discharge from tertiary centre
Secondary Outcome Measures
- Functional capacity [90 days]
Measured using the self-reported Older Americans Resources and Services (OARS) scale at 30 days and 90 days post discharge from tertiary centre
- Frailty [90 days]
Measured using the self-reported SARC-F scale at 30 days and 90 days post discharge from tertiary centre
- Postoperative delirium [Daily (during inpatient admission)]
Assessed once daily using the 4AT delirium assessment tool from day after TAVI until discharge from tertiary centre
- Length of stay at tertiary centre [On discharge: e.g. 2-7 days]
measured in days
- Discharge destination [On discharge: e.g. 2-7 days]
- Unplanned readmissions [90 days]
Measured at 30 days and 90 days post discharge from tertiary centre using hospital records and patient telephone-interview
- Mortality [90 days]
Measured at 30 days and 90 days post discharge from tertiary centre using hospital records and NHS Spine database
