NCT00794001

Brief Summary

Part I (Pilot Phase): The purpose of this study is to examine if formalized data assessment and systematic feedback improves treatment times (i.e. contact-to-balloon time and door-to-balloon time) in patients with myocardial infarction with ST-segment elevation (STEMI). Part II (Implementation Phase): The Purpose is to prospectively investigate if survival can be improved by stringent use of this concept of formalized data analysis and systematic feedback of procedural and clinical data to all participating physicians and other members of the STEMI patients treating personnel. Part III (Advance Phase): The purpose is to develop, introduce and evaluate prospectively an automated, highly standardized feedback tool informing participating centers on key performance characteristics (procedural and clinical outcomes).

Study Arms (1)

Data Feedback

EXPERIMENTAL

The intervention is systematic feedback on performance (using predefined quality indicators) to cardiology, ED, and EMS-stakeholders and staff.

Behavioral: Data analysis and Feedback

Interventions

Data analysis feedback: quarterly meetings with all stakeholders to present data and discuss potential areas of improvement.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • all patients who received a diagnosis of STEMI\* and were transported to the cardiac catheterization laboratory of the primary PCI center with the intention to perform primary PCI.
  • STEMI definition:
  • elevation of the ST-segments of greater than or equal to 0.1 mV in at least two contiguous limb- or precordial leads
  • new or presumable new left bundle branch block in the presence of typical symptoms

You may not qualify if:

  • STEMI-patients with duration of infarct-related symptoms longer than 24 hours are excluded
