Impact of implementation of evidence-based strategies to reduce door-to-balloon time in patients presenting with STEMI: continuous data analysis and feedback using a statistical process control plot.

Abstract

Strategies to reduce DTB (door-to-balloon) time have been previously described. However, there is no well-established data-monitoring system that can be used for prompt feedback. The aims of this study were to use statistical process control (SPC) methodology to measure current processes, to provide real-time feedback on the impact of a change in service delivery and to identify individual outliers for specific investigation.
