Nationally, a minority of STEMI patients from referral centers obtain 1st D2B in <2 h and even fewer in <90 min.
Included were transfer STEMI patients from 9 network hospitals treated in 2007 compared with 2008 to 2011 after installing the following initiatives: 1) established hospital referral system; 2) goal-oriented performance protocols; 3) expedited transport by ground or air; 4) first hospital activation of the PCI hospital catheterization laboratory; and 5) outreach coordinator and patient-level web-based feedback to the referring hospital.
A total of 101 STEMI patients transported in 2007 were compared with 442 STEMI patients transferred after starting these initiatives for STEMI from 2008 to 2011, with the median door-in to door-out time decreased from 44 to 35 min (p < 0.0001), the median 1st D2B decreasing from 109.5 to 88.0聽min (p < 0.0001), and the percentage under 90 min increased from 22.8% to 55.9% (p < 0.0001). Overall, throughout the study period (2007 to 2011), the transport times remained consistent (median 36.5 vs. 36.0 min, p聽= 0.98), whereas the PCI hospital D2B decreased from 20.0 to 16.0 min (p聽<聽0.0001). Length of stay and in-hospital mortality remained low at 3.0 days and under 4%, respectively.
A system-wide network program can achieve sustained (over 4 years) 1st D2B times of <90 min.
