A random sample of patients presenting to this hospital in 1996 and 2000 with chest pain was assessed retrospectively with respect to patient bed stay and associated costs. The laboratory testing protocol had been changed from traditional cardiac markers AST, CK and CKMB, to troponin I, in the intervening period. The average bed stay for patients with chest pain of non-AMI origin was reduced by 2 days, as a result of the change in testing protocol. As ward costs contribute 49% of total cost of treatment, this resulted in decreased cost per patient, and more efficient use of hospital beds.
