Aim
To decrease the door to balloon time for patients with ST segment elevation myocardial infarction (STEMI)who come through the Emergency Department (ED), to meet the standard of less than 90 minutes.
Measures
-
Door to initial ECG – (Goal: 5 minutes)
-
Door to Cath team notified – (Goal: 15 minutes)
-
Door to Departed to Cath Lab – (Goal: 45 minutes)
-
Door to Percutaneous Intervention (PCI) – (Goal: 90 minutes)
Changes
In an effort to decrease the time to less than 90 minutes, a multidisciplinary team was formed. Changes in flow of care, communications, cardiac catheterization team activation and data collection were made. Changes in practice implemented at Mayo Clinic Rochester (MCR) were based on prior published suggestions on how to decrease door to needle time in the era of thrombolysis. Other changes were made based on the PDSA cycle performed through this project.
The most significant changes associated with decreased door to balloon time were:
- Emergency physician activation of cardiac catheterization team by a group page activation
- Predetermined time based goals for each step of the patient care process, i.e. door to ECD of less than 5 minutes, door to team activation of less than 15 minutes, door to ED departure of less than 45 minutes, and finally door to balloon time of less than 90 minutes
- Stong inter-departmental communication between Cardiology, Emergency Medicine, Communications, Quality and Nursing; and 4) Prompt feedback of time based results to staff involved in the care of the STEMI patients

Summary of Results / Lessons Learned / Next Steps
On May 17, 2004 the practice changes were implemented. Data was collected at the bedside in a web based format, created strictly for this population. It was then evaluated by the multidisciplinary team leadership on a bi-weekly basis for accuracy and quality control. Physician support has been instrumental in making these changes happen. Improvement processes and results have been readily shared with the team involved with the STEMI patients.
Our results showed a dramatic decrease in door to balloon time. We had a total of 32 consecutive patients for the timeframe of May 17, 2004 to August 31, 2004. The mean door to balloon time was 70 minutes. Important concepts that assisted in this success were:
-
Get the right people involved. A multidisciplinary team assists in identifying problems/issues, and helps to make changes easier.
-
Communication to all areas of this project is a necessity.
-
Use of the PDSA cycle assisted us in getting rapid changes completed.
-
Make the process as simple as possible.
-
Sharing the data at real time, via graphs, charts, etc, assists others to see the progress and also areas for improvement.
-
Support and commitment from senior leadership is also a big benefit to the success of this project.
