Troponin testing: an audit in three metropolitan hospitals.

چکیده
OBJECTIVE To audit the appropriateness of use of a troponin I assay in three hospitals. DESIGN Cross-sectional survey of use of a troponin assay. SETTING Three hospitals in Melbourne, Victoria, each with an emergency department and a coronary care unit. PARTICIPANTS Patients for whom a troponin I assay was requested between 1 and 7 May 2002, 27-42 months after introduction of the assay. INTERVENTIONS User-focused dissemination of relevant information, including protocols for use, from opinion leaders when the assay was introduced; continuous reinforcement of information in pathology reports. MAIN OUTCOME MEASURES Adherence to protocol for assay use. RESULTS Troponin assays were requested for 333 patients during 351 symptom episodes. A single assay was used in 194 symptom episodes (55%), and serial assays in 157 (45%); proportions were statistically indistinguishable across all three hospitals (chi(2); P = 0.71). Of the 194 single assays, 13 (7%) diagnosed a myocardial infarction. Serial troponin testing in all three hospitals followed the suggested protocol, with mean time between serial assays being more than 6 hours at all hospitals. CONCLUSIONS Adherence to the protocol for serial troponin assay intervals was adequate, but single troponin assays were used extensively and probably inappropriately.

Troponin: think before you request one
Acute myocardial infarction (ACS) is one of the most common presentations in acute hospital settings. Troponin (cTn) has emerged as one of the most sensitive biochemical markers for the diagnosis of ACS. However, if used inappropriately and in the absence of true clinical context then it can be elevated in a number of non cardiac conditions and lead to false clinical diagnosis, inappropriate wo...
متن کاملTrends in Troponin-Only Testing for AMI in Academic Teaching Hospitals and the Impact of Choosing Wisely®.
BACKGROUND Identifying hospitals that are both early and consistent adopters of high-value care can help shed light on the culture and practices at those institutions that are necessary to promote high-value care nationwide. The use of troponin to diagnose acute myocardial infarction (AMI), and not to test for myoglobin or creatine kinase-MB (CK-MB), is a high-value recommendation of the Choosi...
متن کاملHigh sensitivity Troponin T: an audit of implementation of its protocol in a district general hospital.
BACKGROUND Protocols based on newer high sensitivity Troponin T (hsTropT) assays can rule in a suspected Acute Myocardial Infarction (AMI) as early as 3 hours. We conducted this study to audit adherence to our Trust's newly introduced AMI diagnostic protocol based on paired hsTropT testing at 0 and 3 hours. METHODS We retrospectively reviewed data of all patients who had hsTropT test done bet...

OBJECTIVES To describe trends in the availability of biomarker testing in Chinese hospitals and how practice complies with established standards for the diagnosis of acute myocardial infarction (AMI). BACKGROUND Cardiac biomarker testing is standard in high-income countries, but little is known about the availability and use of cardiac biomarker testing in low- and middle-income countries (LM...
