Plain English Summary

Background and study aims
Hospital at home is a service that is provided in some parts of the U.K, but we do not know how this service compares to being admitted to hospital. The aim of this study is to find out if providing healthcare in hospital at home (sometimes called healthcare in the home), instead of
hospital, helps older people to recover from a deterioration in their health. We also aim to find out how much this type of healthcare costs, compared to hospital care, and how people experience healthcare in the home and in hospital.

Who can participate?
Older people who experienced a change in their health, and for whom healthcare in hospital was considered, were invited to participate in this research from nine locations across the UK

What does the study involve?
We collected data on various aspects of their health that included possible confusion, ability to move around and look after themselves and where they were living at six and twelve months after the study had started. We also collected data on resources used, so we could calculate the cost of this type of healthcare.

What are the possible benefits and risks of participating?

Where is the study run from?
Nuffield Department of Population Health, University of Oxford (UK)

When is the study starting and how long is it expected to run for?
November 2014 to January 2020 (updated 10/07/2020, previously: July 2019)

Who is funding the study?

Study information

Scientific title

A multi-centre randomised controlled trial to compare the effectiveness of admission avoidance hospital at home with comprehensive geriatric assessment vs. inpatient comprehensive geriatric assessment on the number of frail older people living at home’


RCT of Comprehensive Geriatric Assessment in a HAH setting v 1.0

Study hypothesis

The aim of this study is to test the cost-effectiveness of admission avoidance HaH with CGA compared with hospital admission with CGA and investigate the generalizability and cost-effectiveness of CGA in settings where health and social care provision vary.

Topic: Primary Care, Ageing; Subtopic: Other Primary Care, Ageing, Ageing; Disease: All Ageing


CGA in hospital at home: Admission avoidance HaH with CGA is a specialist led service providing assessment and a tailored management plan, multidisciplinary management and coordinated care in the patient’s own home. If this service was not available then the patient would be admitted to an acute ward. Usual care will be hospital-based inpatient CGA. CGA is specialist led co-ordinated care involving simultaneous multi-level assessment by a multidisciplinary team to ensure that problems are identified, quantified and mana; Follow Up Length: 12 month(s); Study Entry : Single Randomisation only

Participant inclusion criteria

Older patients with frailty who are aged >65 years and who have been referred to the admission avoidance HaH service with CGA and who would otherwise require admission to hospital for an acute medical event. This will include patients presenting with delirium, functional decline, dependence, falls, immobility or a background of dementia presenting with physical disease

Participant exclusion criteria

1. Patient with acute coronary syndrome
2. Patients needing acute surgical assessment
3. Patients presenting with a suspected stroke
4. Patients who are receiving end of life care as part of a palliative care pathway
5. Patients who refuse the HaH service
6. Patients considered by the clinical staff to be too high risk for home based care, for example those who are physiologically unstable, who are at risk to themselves or if the carer reports HaH care would not be acceptable (in keeping with existing clinical practices for HaH)
7. The presence of a carer will not be a requirement for enrolment and will depend on the individual circumstances of the patient; this will be at the discretion of the clinician responsible for the patient (as is current clinical practice in each centre)
