Thrombolytic therapy in Missouri hospital emergency departments: compliance with the National Heart Attack Alert
Insights
Missouri emergency departments generally follow National Heart Attack Alert Program guidelines for acute myocardial infarction (AMI) treatment. However, significant delays in thrombolytic administration persist, primarily due to decision-making processes.
Area of Science:
- Cardiology
- Emergency Medicine
- Healthcare Administration
Background:
- Thrombolytic therapy is crucial for acute myocardial infarction (AMI) treatment.
- National Heart Attack Alert Program (NHAAP) guidelines aim to expedite AMI care.
- Understanding current practices in emergency departments (EDs) is essential for improving treatment times.
Purpose of the Study:
- To assess the current practices of thrombolytic administration in Missouri acute care emergency departments.
- To evaluate the adherence to NHAAP guidelines for AMI treatment.
- To identify barriers to timely thrombolytic therapy in the ED setting.
Main Methods:
- A self-administered questionnaire was sent to medical directors of Missouri acute care EDs.
- Survey response rate was 75%.
- Data collected included electrocardiogram protocols, thrombolytic stocking and administration practices, physician decision-making authority, and quality improvement programs.
Main Results:
- 92% of EDs had standing orders for electrocardiograms; 80% stocked thrombolytics.
- 98% administered thrombolytics in the ED.
- Despite 87% of EPs being authorized for decisions, 24% required consultation, and less than half achieved door-to-drug times under 30 minutes. Decision-making was the primary delay.
Conclusions:
- Missouri EDs largely follow NHAAP guidelines for AMI identification and treatment.
- Significant delays in thrombolytic administration persist, mainly due to physician decision-making bottlenecks.
- Further process improvements are needed to reduce door-to-drug times for AMI patients.
Abstract:
A self-administered questionnaire concerning the current practice of thrombolytic administration, and the use of National Heart Attack Alert Program (NHAAP) guidelines was mailed to the medical directors of Missouri acute care emergency departments (EDs). Responses from 75% of the EDs surveyed were received. There were standing orders to perform an electrocardiogram at 92% of the EDs surveyed. Thrombolytics were stocked in 80% of EDs and thrombolytics were administered in the ED rather than the ICU or CCU at 98%. The emergency physician (EP) was authorized to make thrombolytic treatment decisions at 87% of the institutions; however, in 24% of the hospitals EPs were required to contact another physician prior to giving thrombolytics. An Acute Myocardial Infarction (AMI) Continuous Quality Improvement (CQI) program was in place at 67%, and 44% of the institutions had an interdepartmental AMI protocol. Less than half of the EDs reported a door-to-drug time of less than 30 minutes. The primary delay in starting thrombolytic therapy was identified as decision-making on the part of the emergency physician and/or consultants. Missouri EDs report that they generally follow the NHAAP guidelines for rapid identification and treatment of AMI, but, there were still significant delays reported in the administration of thrombolytics.
