An NHS England programme to integrate health and social care services slowed the rise in emergency admissions to hospital among care home residents but did not achieve its other aims.
It was hoped that integrating health and social care would ease the growing pressure upon services and reduce the time people spend in hospital. For example, older people who suffer falls could recover at home rather than in hospital, supported by telephone advice, rapid response home visits from health professionals, and other services.
This research is the first evaluation of integrated care models that were piloted across England between 2015 and 2018. Two models focused on the general population; another on care homes.
This evaluation supports the NHS plan to expand integrated care for care home residents. It also cautions that positive outcomes may be slow to appear. There are outstanding questions over the cost-effectiveness of integrated care schemes and how best to structure them.
What’s the issue?
The increasing number of older people with multiple chronic health conditions is placing growing pressure on health and social care. There is widespread consensus that integrating these services will help them deliver the best outcomes for patients. But there is an ongoing debate over which populations and services to target.
This research is the first independent national evaluation of the Vanguard `New Care Models’ programme. This flagship NHS England programme cost about £389 million and covered around 5 million people (around 9% of the population). Fifty local areas across England were selected to be ‘vanguards’ and lead the way in putting five new models of integrated care into practice.
The intention was to reduce hospital use by moving specialist care out of hospitals and into the community or into care homes. The aim was to improve coordination between service providers to make care flexible and responsive to the needs of local populations and care home residents.
Three of the five Vanguard prototypes were evaluated in this research:
- Two schemes moved specialist care for the general population out of hospitals and into the community. They aimed to foster closer collaboration between GPs, hospitals, communities and social care services. These approaches were called Multi-speciality Community Providers (MCPs) and Primary and Acute Care Systems (PACS).
- The other focused on care home residents and aimed to improve the quality and coordination of health, care and rehabilitation services. The Enhanced Care in Care Homes (ECH) model increased the medical support available in care homes and promoted collaboration between the NHS, local authorities, the voluntary sector, carers and relatives.
Researchers obtained monthly counts of emergency admissions and hospital bed-days before and after the Vanguard pilots. They compared outcomes in Vanguard sites with those observed elsewhere.
They found that, with the Vanguard programme:
- over the three-year period, there was a small reduction (of 4.2%) in emergency admissions among care home residents; most of this reduction happened in the third and final year.
- for the population-based sites, a reduction (of 3.1%) in emergency admissions was found only in the third and final year.
- the biggest reductions occurred in adults and older age groups
- there was no significant reduction in bed-days.
Why is this important?
Vanguard’s original aim of immediate improvement may have been unrealistic. Producing marked effects from major reconfigurations of health and social services takes time. Integrated care may not result in large reductions in hospital activity in the short-term.
This evaluation shows that the Vanguard programme did not achieve all its aims. There may be wider, unseen benefits, such as improved patient experience and local relationships . But these outcomes are difficult to quantify and measure over a wide population.
The authors state that the small reduction in emergency admissions was only achieved following extra funding and a dedicated support programme. The evaluation has not assessed the cost-effectiveness of this approach to integrating care.
The 2019 NHS Long Term Plan committed to expanding integrated care models across England. Its initial focus is on policies aimed at care home residents. It will use elements of the Vanguard programme, such as personalised care plans and regular pharmacy input for managing medicines. The current evaluation supports that policy.
Some Vanguard sites reduced the rate of increase in emergency admissions. Others did not. The reasons for that remain unclear and it is not known which integrated care models work best, why they work, and under what circumstances they work. A better understanding of how to integrate health and social care from the perspective of patients and service providers is needed.
This research also highlights that outcomes for integrated care and other initiatives should be assessed over the long-term.
