Plain English Summary

Background and study aims
Cardiovascular disease (CVD) (heart disease) is the leading cause of death, accounting for 27% of all UK deaths. NHS Health Check is a national CVD risk assessment programme for adults in England aged 40-74 without a chronic disease. Typically, general practice records are used to identify those eligible and invite them for a Health Check, where the practitioner assesses their risk of CVD in the next 10 years. This forms the basis of discussions around how to manage and reduce this risk. Nationally, uptake of Health Checks remains around 50%, as just half of those invited for a Health Check attend. This is way below the 75% needed for the programme to be cost-effective. There is some evidence that how people are invited for a Health Check is a strong predictor of whether or not they will attend (i.e., a predictor of uptake). Telephone invitations seem to increase the likelihood that patients will attend their Health Check. Yet, most general practices use standard letters to invite patients as making calls takes more time and is therefore more expensive. Changes to the standard letter could make it more relevant to patients to increase the likelihood that they will attend. This study aims to design and test a NHS Health Check invitation letter personalised to the patient’s level of CVD risk, and to compare the likelihood of patients attending when invited with the personalised letter compared with the standard letter and telephone invitation.

Who can participate?
Patients aged 40-74 who are eligible for and due to have a NHS Health Check at 10 general practices in North Staffordshire

What does the study involve?
Participants are randomly allocated to be invited to attend a Health Check using one of the three methods: standard letter, telephone call, or personalised letter. Participants are invited up to three times before being classified as a non-responder (or if they responded and declined the invitations). The study explores whether the way in which patients are invited predicts whether or not they attend the Health Check, taking other factors such as age and gender into account.

What are the possible benefits and risks of participating?
Patients may benefit from an increased likelihood of attending the Health Check. The potential risks include patients in the personalised letter group finding the risk-tailored messages distressing or difficult to understand. However, considerable development work and public consultation was undertaken to mitigate this risk.

Cardiovascular disease


The three trial arms are the different methods of invitation to attend a NHS Health Check (with attendance/non-attendance as the outcome):
1. Standard letter (control) - patients receive a letter with the same content (the most recent national letter template), with accompanying Health Check information leaflet.
2. Telephone - patients are invited by telephone, usually by the reception staff (a guide was provided to practices to standardise the type of information relayed to patient.
3. Personalised letter - risk-personalised letter templates developed to include messages appropriate to different levels of CVD risk based on the QRISK 10-year score (templates for 3 risk categories - High ≥20%; Medium 10-19.9%; low <10%).

Random allocation of individual patients within practices was completed within EMIS using bespoke searches: an eligible cohort search was run using the existing search based on the national NHS Health Check criteria; search was run to randomly select 33.3% of the cohort and allocate them to Arm 1; search was run to randomly select 50% of the remaining cohort and allocate them to Arm 2; the remaining 33.3% of the cohort were allocated to Arm 3. For each arm, patients are invited up to three times before being recorded as a non-responder (and non-attender).

Results and Publications

Publication and dissemination plan

The study protocol has not been published, but can be requested from the study team. The main result paper should be submitted by December 2017. The trialists hope to present findings at conferences in 2018 (e.g., Annual NHS Health Check conference in February 2018, if accepted to present).

IPD sharing statement
The datasets generated during and/or analysed during the current study are not expected to be made available because the third party data sharing agreement between Staffordshire University and general practices did not include statements regarding further sharing of data. The data will remain stored at Staffordshire University.
