4 Data collection from ACC & EMS Development of a central database Comparison of EMS to hospital patient records Data validation/integrity checks Decision Support (data analysis) of STEMI outcomes UT Health - Role

5 This is the inaugural report of the Dallas County STEMI system of care Use caution when interpreting these figures since they are strictly baseline for everybody involved! Data are for Oct to Dec Data collected from EMS agencies and hospitals (through ACC Action Registry GWTG) 5 Dallas Hospital Market

6 Overview to Methodology Our primary focus is on collecting and analyzing both pre-hospital (EMS) and hospital data for STEMI/NSTEMI in Dallas County To capture SOAR, we prefer to have complete records from time of 911 dispatch to hospital discharge We need to match EMS Hospital data, preferably using PCR or Incident # – For this quarter, we had to use DOB and incident date/hospital arrival date since Aux3 field was not widely populated 6

7 Overall Data Quality - Reminders 7 This project requires good data entry from both EMS & hospitals! We cannot identify if 10-key entry errors exist Lots of “null values”; for instance, several patients had PCI=yes, but were missing device times or dates EMS: arrival times at facility missing in many cases 24 hour time clock (e.g., 6 pm = 18:00)

8 Reporting Agencies Summary 8 OrganizationsReceivedMissing 14 hospitalsXX Carrollton, Cedar Hill, Coppell, Dallas Fire, Desoto, Duncanville, Farmers Branch, Garland, Grand Prairie, Highland Park, Irving, Lancaster, Mesquite, Richardson, Rowlett, Sachse, Seagoville, Sunnyvale, and University Park XX Wilmer, Hutchins, Glenn Heights, CareFlite –Balch Springs, Addison XX

9 Comment on EMS Data 9 Overall, we were not able to provide meaningful data analyses on most of the EMS data for Q4 due to Missing data Data quality, Issues in EMS reporting Data timing and integrity issues We expect to have this resolved for Q1 2011

10 Patient Population Q

11 Q Patient Volumes admissions in the NCDR/ACC registry 594 unique patients 15 participating hospitals (we’ve received data for 14 this quarter) 203 STEMIs noted (34% of all registry cases) 129 STEMI, PCI, non-transfer cases in total 123 Primary PCI form the population for all D2B and other timing outcomes

12 Patient Breakdown for Outcome Calculations 12 Total Cases 603 STEMI Noted 203 NSTEMI 400 To Cath. Lab 167 (82% of STEMI) No PCI 36

24 STEMI Outcomes 24 The shortest D2B time was 23 Minutes Average length of stay for all STEMI (non-transfer, primary PCI) patients was 3.6 days We had 9 deaths in the STEMI population (4.4%)
