Datasets describing the introduction of the high-sensitive troponin in the emergency department.

Chest pain is a common clinical condition in the emergency department. A high sensitive (hs) troponin test assay may help to identify patients with acute coronary syndrome earlier compared to conventional tests but also entails the risk of a high proportion of positive test results in patients without cardiac disease. We assessed the impact of the introduction of the hs-troponin test in clinical practice in an emergency department. We compared December 1, 2009 until November 30, 2010 (standard test period) to December 1, 2010 - the date of the introduction of the hs-troponin assay - until December 31, 2011 (hs troponin test period) of patients presenting with chest pain to one of the ten largest hospitals in Switzerland. We identified electronic health records using the following ICD-10 codes: R06.4 (hyperventilation), R07.1 (chest pain when breathing), R07.2 (precordial pain), R07.3 (other chest pain), and R07.4 (chest pain not specified), I20 (angina pectoris), I21 (acute MI), I22 (recurrent MI), I23 (complications after acute MI), and I24 (other acute ischemic heart disease). Included were all medical records of adult patients (≥18 years) presenting to the ED with chest pain and with ≥1 troponin test. Excluded were records without troponin test, pregnancy, trauma patients/life-threatening conditions, malignant disease, current fracture, renal replacement therapy/severe kidney failure (creatinine clearance <30ml/min/1.73m
