Conclusions
Based on this study, we believe that routine coagulation testing in adults presenting to hospital with chest pain is unnecessary. This practice should be replaced by a coagulation testing policy based on an increased risk of coagulopathy. This risk could be assessed rapidly, based on a history of anticoagulant use, or known or suspected liver disease. Our findings are only applicable to adult patients presenting to the ED with chest pain. Further investigation is necessary to determine if protocolised coagulation screening is generalisable to other patient populations.
