Abstract

Objectives Recent guidance recommended use of high-sensitivity troponin for rapid rule out of myocardial infarction (MI) in the English health service. We aimed to determine the extent of implementation of this guidance across English hospitals.

Methods This study conducted a cross-sectional questionnaire survey of 131 English acute hospitals with over 10 000 admissions per year.

Results We received 125/131 responses (95%), with 110/125 (88%) reporting use of a high-sensitivity troponin assay and responses showing progressive implementation over the last 10 years. High-sensitivity troponin was reported to be used for rapid rule out of MI in 92/110 Trusts (84%). Review of guidelines received from 95/110 Trusts identified that 71/95 (75%) provided guidance for rapid MI rule out with high-sensitivity troponin: 57 recommended testing at 0 and 3 hours, 4 recommended testing at 0 and 2 hours, and 9 recommended testing at 0 and 1 hour, and timing was unclear at one Trust.

Conclusions English acute hospital Trusts report widespread implementation of high-sensitivity troponin for rapid rule out of MI, with most recommending testing at 0 and 3 hours.
