Door to needle times bulls' eye or just bull? The effect of reducing door to needle times on the appropriate administration of thrombolysis: implications and recommendations.

摘要

The provision of thrombolysis in a timely fashion is the mainstay of treatment for acute myocardial infarction. With the publication of the National Service Framework (NSF) for Coronary Heart Disease increasing efforts have been put into the reduction of the 'pain to needle time'. Of the various parts of the patient journey the time delays in hospital are the easiest to resolve. Published research shows that the time taken for the patient to call for help is intractable at present. Therefore, the obvious target for the reduction in the overall time from pain to treatment is the in hospital portion of the delay (the door to needle time). There are several methods that have been recommended for the reduction of the door to needle time. However, the increasing focus on the door to needle time is leading health care providers away from other issues such as the safety and accuracy of assessment by a non-cardiologist. Furthermore, the standards for audit of the door to needle time have not been set by the NSF and this has led to the presentation of selected data and the avoidance of discussing issues of accuracy and appropriateness.
