Plain English Summary
Background and study aims
Acute coronary syndrome (ACS) refers to a group of conditions due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. It encompasses a range of sudden heart conditions, including heart attack and unstable angina attack (sudden chest pain). ACS mainly happens due to narrowing of the blood vessels which supply the heart due to a build-up of plaque (a fatty, sticky substance) on the walls of arteries. The GRACE risk score tool is a special tool which can be used by healthcare professionals (such as doctors) to calculate the risks of further heart attack or death after acute coronary syndrome (type of unstable angina attack or heart attack), by looking at medical information that is routinely collected during hospital stays. The aim of this study is to find out whether there is a difference in patient’s health status following an unstable angina attack or a heart attack if treated according to usual care or if treated using the GRACE risk score tool.
Who can participate?
Adults who have been admitted to hospital with a suspected acute coronary syndrome.
What does the study involve?
Participating hospitals are randomly allocated to one of two groups. Hospitals in the first group use the GRACE risk score tool within routine clinical assessment and management procedures. This involves individual participants who agree to take part having their GRACE risk score calculated and used to help decide their treatment. Hosptials in the second group continue to follow their current practice. In both groups, participants complete a general health assessment and a short questionnaire at the start of the study and then again 12 months later to assess their health status. Participants’ long-term progress relating to their heart condition is also assessed by reviewing electronic medical records.
What are the possible benefits and risks of participating?
There are no guaranteed benefits of participating, however the information gained from this study could help improve the treatment of people with ACS in the future. There are no notable risks involved with participating.
Where is the study run from?
Thirteen NHS hospitals in England (UK)
When is the study starting and how long is it expected to run for?

Scientific title
Effectiveness of the GRACE risk score on the management and outcome of patients hospitalised with non-ST elevation acute coronary syndrome
Acronym
UKGRIS
Study hypothesis
Study aim:
The aim of this study is to evaluate the effectiveness of the systematic clinical application of the GRACE risk score.
Hypothesis:
Compared with current standard care, the implementation of the GRACE risk score tool by healthcare professionals for patients hospitalised with NSTEACS increases the use of Class 1 guideline-indicated therapies for the management of NSTEACS and reduces the composite endpoints of cardiovascular death, non-fatal myocardial infarction, new onset heart failure (with admission) and cardiovascular readmission at twelve months.

Intervention
Sites are randomised centrally using minimisation including a random element at the CTRU to either the intervention (use of the GRACE risk score) or to current standard care at their site on a 1:1 basis stratified by hospital ACS Volume and primary PCI capability. Sites are randomised prior to opening to recruitment. Sites are excluded from participating in the study if they currently use the GRACE risk score for guiding treatment in this group of participants. Participants are then registered onto the study following a site opening to recruitment and the participant consenting to take part in the study.
Intervention arm: The trial will aim to embed the GRACE risk score tool within routine clinical assessment and management procedures at each of the hospitals randomised to the intervention. Each consenting participant will have their GRACE risk score and corresponding risk of six month mortality estimated by the appointed local research staff / healthcare professional as soon as possible after admission (ideally within twelve hours). Each participant will be classified as either ‘low’ (score:<109), ‘intermediate’ (score: 109 to 140) or ‘high’ (score: >140) risk estimate of six month mortality and this will be clearly recorded on the Risk Scores CRF with a list of abbreviated guideline recommendations for the management of NSTEACS. The trial will collect recommendations followed and reasons for not following recommendations.
Control arm: Participants will be registered into the study and the site will continue with their current practice. CTRU staff will be in regular contacts with sites during the recruitment phase to ensure sites do not change their practices to incorporate the GRACE risk score in their treatment of this group of participants.
All participants will consent to participate in this study following their admission to hospital. Following consent their baseline information will be collected and, dependent on the arm of the trial, their GRACE risk score will be calculated and their treatment recommendations recorded or normal practice will be followed. The recommended timelines for this happening is within 12 hours of the participant being admitted to hospital. Following on from this, a member of the research team will work through a frailty score with the participant and then the participant will complete a short questionnaire.
On discharge from hospital (or death) further data will be collected as to what treatment and medication the participant received during their admission. 12 months after the patient was registered into the study, the patient will be posted a further short questionnaire to complete and send back to the CTRU. The study team will also be applying for follow up data for the participants via electronic health records.

Primary outcome measures
1. The proportion of care processes (Class 1 guideline-indicated therapies) received across all participants in each hospital as assessed using care processes reported from time of onset of chest pain until discharge from hospital (or death) as recorded on the end of hospital stay CRF.
2. Composite endpoint of cardiovascular death, non-fatal myocardial infarction, new onset heart failure (with hospitalisation) and cardiovascular readmissions at 12 months assessed through electronic health record review at 12 months
Secondary outcome measures
1. Health-related quality of life is measured using the EQ-5D-5L questionnaire at baseline and 12 months
