Meeting National Service Framework goals for patients presenting with acute myocardial infarction
Insights
This study shows that emergency departments can meet thrombolysis targets for acute myocardial infarction (heart attack) patients. However, improving call-to-door times is crucial for achieving faster overall treatment.
Area of Science:
- Cardiology
- Emergency Medicine
- Healthcare Quality Improvement
Background:
- The National Service Framework for coronary heart disease set standards for acute myocardial infarction (AMI) management in March 2000.
- This study assesses an inner-city teaching hospital's emergency department (ED) thrombolysis performance against these standards.
Purpose of the Study:
- To evaluate the effectiveness of an ED's thrombolysis protocol for AMI patients.
- To assess adherence to National Service Framework standards for AMI treatment.
Main Methods:
- Prospective data collection via a clinical pathway for all patients receiving thrombolysis in the ED (February 2000 - January 2001).
- Monthly multidisciplinary audit meetings and regular feedback to nursing and medical staff.
- Comparison of door-to-needle times between ED teams and duty physicians.
Main Results:
- 127 patients received thrombolysis; 92 (72%) were immediately eligible.
- 77% of eligible patients achieved door-to-needle times under 30 minutes; 38% under 20 minutes.
- ED teams achieved door-to-needle times under 30 minutes in 84% of cases, compared to 53% for duty physicians. Call-to-door times averaged under 30 minutes for 20% of patients.
Conclusions:
- The 2002 thrombolysis target set by the National Service Framework is achievable.
- The 2003 target remains ambitious, with call-to-door times significantly impacting overall call-to-needle times.
- ED teams demonstrated greater efficiency in thrombolysis administration compared to duty physicians.
Background:
The National Service Framework for coronary heart disease established clear standards for the management of patients with acute myocardial infarction in March 2000. This study evaluates an emergency department's thrombolysis performance in light of these standards.
Setting:
Inner city teaching hospital emergency department.
Methods:
The data were prospectively collected using a formal clinical pathway for all patients receiving thrombolysis in the emergency department between February 2000 and January 2001. Cases were reviewed at monthly multidisciplinary audit meetings. Regular feedback complemented routine teaching for both nursing and medical staff.
Results:
127 patients were thrombolysed, of whom 92 (72%) were immediately eligible. Some 77% of these had a door to needle time of less than 30 minutes and 38% less than 20 minutes. Twenty per cent of patients had a call to door time of less than 30 minutes. Some 84% of patients managed by the emergency department team had a door to needle time of less than 30 minutes compared with 53% of those patients seen by duty physicians.
Conclusions:
The thrombolysis target set by the National Service Framework for April 2002 is achievable. The target set for April 2003 remains an ambitious goal. Overall call to needle times are undermined by call to door times. Emergency department teams may be more efficient than duty physicians in processing patients needing thrombolysis.
