Plain English Summary
Background and study aims
The NHS Health Check programme has been set up to help prevent heart disease, stroke, diabetes, kidney disease and some types of dementia in the general population. Everyone aged 40 to 74 and not either already diagnosed with one of these conditions, or have certain risk factors, will be sent an invite once every 5 years to attend an appointment to check on their risk of developing these diseases. They will be then given support or advice on how to manage or reduce such risks. The programme is a policy priority for the Department of Health, NHS England, Public Health England and local authorities in their efforts to tackle premature death and promote healthy lifestyles. However, the number of people who join the programme are significantly lower than desired, at around 50 per cent. Local authority commissioners of the NHS Health Check currently use a range of different letters and marketing to encourage those eligible to attend. However, there has not to date been any robust research into what type of letters or marketing strategies will are most likely to lead to an increase in the number of people taking part in the programme. There is compelling evidence in the field of behavioural science to suggest that a low cost intervention within the content of the invitation letter or a reminder text message may be effective at changing peoples behaviour. The aim of this study is to determine what type of patient invitation letter would be most likely to successfully encourage people to enrol on the NHS Health Check programme. The results will be used to help promote the uptake of Health Checks.
Who can participate?
People eligible for an NHS Health Check in the Borough of Northamptonshire during the duration of the study
What does the study involve?
This study tests whether a number of small, low-cost changes to the invitation process for Health Checks can increase uptake. Patients are randomly allocated to receive the usual letter of invitation (control), a new, shorter, action focused letter containing some questions and answers relating to the Health Check (intervention 1), or a shorter letter with a reference to the cost of the Health Check appointment (intervention 2).
What are the possible benefits and risks of participating?
There are no risks to participants. The standard NHS leaflet explaining the risks of attending a Health Check, or not, is including in both the control and intervention letters.
Where is the study run from?
GP surgeries in Northamptonshire (UK)
When is the study starting and how long is it expected to run for?

3. A shorter letter with a reference to the cost of the Health Check appointment
