Improving the Referral of Patients With Chest Pain — Urgent  

Myocardial Infarction Clinical Trial

Official title: A Prospective Cohort Study to Improve the Accuracy of Referrals of Patients With Chest Pain to the Emergency Department: to Decrease the Delay in Acute Coronary Syndrome Patients and Rule Out Non-cardiac Chest Pain Patients (URGENT)

Status Terminated

Clinical Trial Summary

Rationale: This study aims to aid the general practitioner (GP) in the diagnostic dilemma of chest pain patients. Patients with acute coronary syndrome (ACS) should be referred to the hospital promptly, though referring all patients with chest pain is not feasible, as up to 80% of the patients with chest pain in the primary care do not have ACS.

Objective: The primary objective is to refer patients who contact the out-of-hours GP cooperation (GPC) with suspicion of ACS more accurately with a hypothesized reduction of 10% in unnecessary referrals.

Study design: This study is a prospective, observational, prevalence-based cohort study within the standard care of ACS patients.

Study population: All patients with chest pain, or other complaints suspect of ACS, will be included in which the GP at the GPC is in need of further diagnostics to come to a decision of referral. The follow-up will be a registry of all patients with suspected ACS referred to the emergency department (ED). Patients with typical complaints of ACS, and thus a high suspicion, will be excluded and referred promptly.

Intervention: Triage nurses working at the GPC will receive specific ACS training. Patients who arrive at the GPC with non-typical chest pain, will be screened for enrolment within the study. The GP evaluates patients using the Heart score, this includes electrocardiogram recording and point of care (POC) troponin testing. With the Heart score the GP can make an informed decision to refer the patient to the ED.

To evaluate the intervention a registry of all patients referred to the ED with suspected ACS will be compared to a baseline registry performed from the 1st of September 2015 until the 1st of March 2016. Patients not referred to the ED, will have a (standard) high-sensitivity troponin and a POC troponin as follow-up at least four hours (up to 24 hours) after first measurement.

The burden and risks associated with participation, benefit and group relatedness: Patients enrolled within this study will receive a finger stick blood test and electrocardiogram recording at the GPC and a finger stick blood test and a venous blood test at least four hours after first troponin measurement. We may follow-up by telephone if we can not obtain the required information from medical records. We expect no adverse events and there are no expected risks associated with this protocol. We expect patients with ACS to be referred more accurately and more promptly to the ED and thus lowering risks.
