Key result
Implementation of a 4-strategy quality improvement protocol significantly reduced median door-to-balloon time for STEMI patients from 125 minutes to 86 minutes (P<0.0001).

Do systems-based quality improvement strategies reduce door-to-balloon time in STEMI patients?
Absolute Event Rate: 86% vs 125%
p-value: p=<0.0001
Implementing targeted systems-based quality improvement strategies significantly reduced median door-to-balloon times for STEMI patients, achieving the guideline-recommended target of <90 minutes.
Parikh et al. (2009) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=243). 4-strategy quality improvement protocol vs. Previous STEMI protocol was evaluated on Median door-to-balloon time (DBT) (p=<0.0001). Implementation of a 4-strategy quality improvement protocol significantly reduced median door-to-balloon time for STEMI patients from 125 minutes to 86 minutes (P<0.0001).
