NCT03421873

Brief Summary

Chest pain is a common presenting complaint at the Emergency Department (ED). Many of these patients undergo lengthy assessments in the ED or are admitted which contributes to ED and hospital crowding as well as a substantial health care burden. The now commonly used high-sensitivity cardiac troponin assays enable faster rule-out of acute myocardial infarction (AMI). The European Society of Cardiology (ESC) recommend the use of a 0h/1h high-sensitivity cardiac troponin T (hs-cTnT) protocol, but all studies so far have been observational. The safety and effectiveness of the protocol when implemented in routine care is thus unknown. The aim of this study is to determine the safety and effectiveness of the ESC 0h/1h hs-cTnT protocol, supplemented with clinical assessment and ECG, when implemented in routine care.

Outcome Measures

Primary Outcomes (2)

  • AMI and all-cause death

    Comparison of the rate of AMI and all-cause death within 30 days from ED presentation in patients discharged from the ED during the intervention period versus the control period (safety)

    30 days from ED presentation

  • ED length of stay

    Comparison of ED length of stay in patients discharged from the ED during the intervention period versus the control period (effectiveness)

    Through discharge from the ED, on average 5 hours after ED presentation

Secondary Outcomes (8)

  • Proportion of ED patients discharged

    Through discharge from the ED, on average 5 hours after ED presentation

  • Proportion of patients fulfilling 0h/1h hs-cTnT criteria who have undergone objective testing

    30 days from ED presentation

  • Non-ACS coronary care unit admissions

    Throughout index hospital visit, on average 2 days after ED presentation

  • Inappropriate coronary angiographies

    Throughout index hospital visit, on average 2 days after ED presentation

  • Total hospital length of stay

    Through discharge from the index hospital visit, on average 2 days after ED presentation

  • +3 more secondary outcomes

Study Arms (2)

Intervention (Implementation) group

Chest pain patients enrolled during a 10 month period after a change in routine care, i.e. the implementation of a 0h/1h hs-cTnT protocol

Other: 0h/1h hs-cTnT protocol

Control group

Chest pain patients managed at the 3 intervention EDs during the corresponding 10 months of the previous year (intervention hospitals acting as their own controls) as well as chest pain patients managed during the corresponding before-and-after period at EDs not implementing the protocol (concurrent controls).

Interventions

Implementation of a 0h/1h hs-cTnT protocol in routine care
