Improving the Accuracy of Referrals of Patients With Chest Pain (URGENT2)

June 9, 2022 updated by: Braim Rahel, VieCuri Medical Centre

A Multicentre Randomized Controlled Trial to Improve the accUracy of Referrals to the emerGency departmEnt of patieNts With chesT Pain by Using the Modified HEART Score in Emergency Medical Transport (URGENT 2.0)

This is a multicenter, prospective, investigator-initiated, randomized controlled trial aiming to reduce the percentage of non-cardiac chest pain (NCCP) patients admitted to the cardiac emergency department (ED) by performing the modified HEART score by emergency medical transport (EMT) personnel.

Study Overview

Detailed Description

Patients with acute coronary syndrome (ACS) should be referred to the hospital promptly. However, referring all patients with chest pain is not feasible, as recent studies showed that up to 80% of the patients with acute chest pain do not have ACS.

Bedside point-of-care (POC) high sensitive troponin testing (in fingerprick blood/capillary blood) and the modified HEART score have become available and might play a substantial role in the triage and diagnosis of chest pain patients in a pre-hospital setting by general practitioners (GPs) and EMT personnel in the future. We hypothesize that patients with chest pain can be referred more accurately by using the modified HEART score.

Exclusion Criteria:

  • Electrocardiographic ST-segment elevation/High suspicion of STE-ACS.
  • Suspicion of an acute non-coronary diagnosis e.g. pulmonary embolism, thoracic aortic dissection or other life-threatening disease.
  • Patients presenting cardiogenic shock, defined as: systolic blood pressure <90mmHg and heart rate >100 and peripheral oxygen saturation <90% (without oxygen administration)
  • Patients presenting with sudden onset heart rhythm disorders and second or third degree atrioventricular block.
  • Patients with confirmed ACS, PCI or CABG <30 days prior to inclusion.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention group

Chest pain patients in the intervention group will be assessed by EMT personnel by performing the modified HEART score (including POC high sensitive troponin-I measurement (POC HS cTnI)) and the referral policy depends on the result.

  • In case of a low modified HEART score (modified HEART 0-3) patients will not be referred to the cardiac ED.
  • Patients with a modified HEART score >3 are directly referred to the cardiac ED after evaluation. These patients will receive standard care.

The modified HEART score was developed in 2007 and has been validated to stratify the risk of short-term adverse cardiac events in patients with chest pain at the ED. Negative predictive value (NPV) of the modified HEART score for ACS as well as positive predictive value (PPV) for major adverse cardiac events (MACE) within 6 weeks after presentation is high.

The modified HEART score is an acronym for history, ECG, age, risk factors and troponin at arrival.The components can be rated 0,1 or 2 points each and result in a total score between 0 and 10.

Active Comparator: Control group
Chest pain patients in the control group will receive standard triage and standard care according to the local (EMT) protocol.
Standard care and triage of chest pain patients according to the local (EMT)protocol.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The incidence of non-cardiac chest pain (NCCP) patients admitted at the cardiac ED (percentage, %)
Time Frame: 30 days
Evaluation of the percentage of NCCP patients admitted to the cardiac ED by performing the modified HEART score in comparison to our control group (regular triage and care). We aim to detect a reduction of minimal 10% in unnecessarily referred chest pain patients (NCCP patients) but expect an even higher percentage. A lower percentage of NCCP patients indicates improval of the triage of chest pain patients.
30 days
The incidence of MACE (percentage, %)
Time Frame: 30 days, 6 months and 1 year

The mortality and major adverse cardiovascular events (MACE) i.e. acute myocardial infarction, non-elective percutaneous coronary intervention, coronary artery bypass grafting or all cause death within 30 days, 6 months and 1 year after initial presentation in the intervention group versus control group.

We aim that the proportion of MACE in the intervention group (modified HEART score) is non-inferior to the control group (regular care and triage). Preliminary results of the second phase of FAMOUS Triage trial showed 15.7% (13.1-18.6) MACE rate.We used the expected incidence of 15.7% as the point estimate (meaning no difference between control and intervention). A higher MACE rate (%) in the intervention group suggests a worst outcome.

  2. Male versus female patients
  3. Patients referred by GP versus patient referred by triage nurse at GP cooperatives (GPC) versus self referrals.

Time Frame: 30 days, 6 months and 1 year

Prespecified subgroup analyses of primary outcomes will be performed for:

Cost-effectiveness analysis
Time Frame: 30 days, 6 months and 1 year
This economic evaluation investigates the health care costs of full implementation of a prehospital rule- out strategy with the modified HEART score (intervention group) compared with regular care and standard transfer to the hospital to rule out ACS (control group). Health-care costs will be prospectively recorded at baseline and at 30 days follow-up, 6 months and 1 year. This includes health care costs due to readmission, diagnostic testing, revascularization etc. The cost of hospital treatment is determined by the Dutch Diagnose Behandel Combinatie (DBC) hospital reimbursement system and the DBC information system, similar to the international diagnosis related group system.
30 days, 6 months and 1 year
Assessment of the diagnostic value of the modified HEART score.
Time Frame: 30 days, 6 months and 1 year
Positive Predictive Value (PPV), sensitivity, specificity and Negative Predictive Value (NPV) of the modified HEART score for ACS will be calculated.
30 days, 6 months and 1 year
Overview of the actual diagnosis of patients with a low modified HEART score (0-3).
Time Frame: 30 days
To evaluate the percentage of patients in this specific group with ACS versus no-ACS.
