This is a plain English summary of an original research article
Annual health checks for people with intellectual disabilities in England, introduced in 2009, reduced emergency admissions for potentially preventable conditions, such as constipation or choking on food, by about a quarter. However they have not reduced overall emergency or elective admissions to hospital. The benefits were clearer for people with more severe and complex health needs.
An increasing proportion of the UK’s 1.5 million people with an intellectual disability live in the community, which makes the role of their GP important to their overall health. People with an intellectual disability often have associated health issues, such as heart problems and epilepsy. They are more likely to die earlier than the general population. The finding from this study should be seen in the context of increasing emergency admission rates for most conditions recently.
Annual health checks, introduced with extra funding as an enhanced service, are intended to improve the health of people with intellectual disabilities by identifying and treating health problems earlier, and improve links with GP practice staff. Uptake has been low with only half of eligible adults receiving health checks by 2012.
The encouraging preliminary findings should stimulate further research on the cost-effectiveness of health checks. Looking for the reasons why some practices achieved high uptake and low admission rates might also help decisions makers assess how widely these checks should be encouraged for this underserved population group.
Why was this study needed?
Around 1.5 million people in the UK have an intellectual disability. The extent to which someone’s ability to function is affected by their intellectual disability varies, with some people able to live very independently whilst others require more support.
A recent NIHR-funded article found that people with intellectual disabilities in England are more likely to die young than people in the general population, and that more than a third of early deaths were potentially amendable to health care interventions. The NHS in England introduced annual health checks for people aged 14 and over with intellectual disabilities in 2009.
This NIHR funded study set out to investigate whether annual health checks had any impact on the number of hospital admissions for people with intellectual disabilities.
What did this study do?
This study analysed hospital admissions for people with an intellectual disability from across English GP practices. Emergency admissions, preventable emergency admissions and elective admissions were all looked at separately. Practices with high and low uptakes of health checks were compared. Practices that had seen 50% or more of their patients with intellectual disability were classified as having a high-uptake of health checks (126 practices) while those seeing less than 25% were classified as non-participating (95 practices). Also, the number of hospital admissions for individuals who had received a health check were compared to matched individuals admitted to hospital who had not received a health check.
This was not a trial, and practices were not randomised or matched. It took the opportunity presented by the introduction of the programme to observe and compare practices with low uptake with those who had higher uptake. It also looked at the reasons for admission for people with intellectual disability who had had health checks compared to those who had not. One limitation of the approach is that practices with a high-uptake had, on average, more adults with intellectual disability in their practice, and may therefore also be more likely to provide improved care for people with intellectual disability, possibly exaggerating any positive outcome.
What did it find?
- There was no significant difference in overall emergency admissions amongst people with intellectual disabilities in GP practices with high-uptake compared to non-participating practices (incident rate ratio [IRR] 0.97, 95% confidence interval [CI] 0.78 to 1.19).
- Emergency admissions for conditions requiring hospitalisation – such as constipation or inhalation of food – that are potentially preventable through better clinical management were lower in high-uptake practices compared to non-participating practices (IRR 0.74, 95% CI 0.58 to 0.95). These conditions are called “ambulatory care sensitive conditions”.
- There was no difference in emergency admissions between people with intellectual disabilities who had or had not received a health check (IRR 0.96, 95% CI 0.87 to 1.07). There was also no difference in elective admissions.
- There was a reduction in preventable (i.e. ambulatory care sensitive conditions) emergency admissions amongst people who received a health check compared to people who had not received a health check (IRR 0.82, 95% CI 0.69 to 0.99).
What does current guidance say on this issue?
NHS England introduced annual health checks for people with intellectual disabilities in 2009 as a Directed Enhanced Service in primary care. Health checks for people with intellectual disabilities are designed to improve their health by identifying and treating medical conditions early. This includes screening for health issues that are more common in people with intellectual disabilities and health promotion (such as healthy eating).
The Royal College of General Practitioners has produced guidelines for GPs carrying out health checks. It recommends that all health checks include an assessment of feeding, bowel and bladder function; assessment of behavioural disturbance and assessment of vision and hearing. There are also some syndrome-specific checks that GPs carry out for people with specific intellectual disabilities that are associated with physical health problems, such as Down’s syndrome.
What are the implications?
Although health checks did not affect overall hospital admissions, they did reduce emergency admissions for conditions that may be prevented through improved clinical management. Their impact was also greater for people with more severe and complex needs.
Increasing numbers of people with intellectual disabilities live in the community, rather than medical residential facilities, and therefore GPs are important in ensuring their health needs are met. Currently under 60% of GP practices offer annual health checks to people with intellectual disabilities. While these findings are encouraging, the observational nature of the study means that it is hard to split apart the effect of the health check from other factors.
