    Newsom Score for Non-traumatic Chest Pain

    Rules out need for chest x-ray in chest pain patients (non-traumatic).

    INSTRUCTIONS

    Use in patients presenting to the emergency department for non-traumatic chest pain.

    When to Use
    Pearls/Pitfalls
    Why Use

    Patients presenting to the emergency department for non-traumatic chest pain.

    • Application of this decision tool would have missed five clinically relevant diagnoses in the study population: three pneumonias and two pleural effusions.

    • The prevalence of clinically relevant ED findings on chest x-ray in the study population was 6.4%. In populations where prevalence is higher, negative predictive value (98.4% in the study) would decrease (Newsom 2018).
    • Can potentially safely eliminate unnecessary x-ray in patients presenting to EDs with non-traumatic chest pain (92.9% sensitive, NPV 98.4% for clinically relevant ED findings on chest x-ray).
    • In the validation study, application of the score would have decreased chest x-ray usage by 28.9%.
    • The study authors estimate a potential decrease of $58 million per year in healthcare costs as a result of the potential decrease number of chest x-rays performed with application of the clinical decision tool.
