Reduction in hospital time to thrombolytic therapy by audit of policy guidelines

Abstract

Despite the importance of early thrombolysis in the treatment of acute myocardial infarction, unacceptable delays in drug administration still occur in hospital. From March 1989 we decided to monitor our performance, and thereby to reduce avoidable in-hospital delay to a minimum. Potential candidates for thrombolytic therapy were identified by paramedic ambulancemen whenever this was feasible. Rapid check-lists were used for inclusion and exclusion criteria in the Accident and Emergency Department. A target of 15 min was set for time to treatment, and reasons for any gross deviation (greater than 30 min) were explored in each instance. As a result of these strategies, we achieved a median time from admission to initiation of thrombolysis in 50 consecutive patients of 17 min. The 39 patients treated with injections of APSAC as opposed to infusions of streptokinase had a median in-hospital delay to treatment of only 13 min.
