The National Heart Attack Alert Program: Progress at 5 Years in Educating Providers, Patients, and the Public and Future Directions

Abstract

The National Heart Attack Alert Program (NHAAP) was launched by the National Heart, Lung, and Blood Institute in 1991 with the goal of reducing morbidity and mortality from acute myocardial infarction (AMI) through the rapid identification and treatment of individuals with symptoms and signs of an AMI. To achieve this goal, the NHAAP established objectives for each of three phases of action where treatment delays can occur: in the hospital, the prehospital setting, and the patient/bystander arena. The NHAAP initially directed its educational efforts toward emergency department professionals. Recommendations for reducing delays in emergency department identification of patients presenting with heart attack symptoms were developed by a working group convened in late 1991. These recommendations were published in February 1994 in a peer-reviewed journal reaching more than 17,000 emergency physicians. The NHAAP worked in a partnership with its coordinating committee, representing 40 health professional, voluntary, and government organizations, to extend the reach of the report's recommendations to their members. Strategies for promoting the emergency department recommendations included publication of excerpts in newsletters and journals of the medical, nursing, and prehospital provider organizations represented on the NHAAP Coordinating Committee, and through symposia at annual meetings. Industry assisted with dissemination efforts and with implementing a continuous quality improvement program based on the paper's recommendations. The NHAAP also developed, with the Joint Committee on Accreditation of Health Care Organizations, a time-to-treatment indicator for thrombolytic therapy to be incorporated into their Indicator Measurement System (IMSystem). To track achievement of the objectives related to the Hospital Action Phase, national data sources for emergency department management of patients with AMI were evaluated at the 5-year point of the NHAAP. Data from a national registry showed that the median time from presentation at the emergency department to receiving thrombolytic therapy declined by about one third between 1992 and the last half of 1995. The percentage of all Medicare patients receiving thrombolytic therapy within the recommended 30 minutes after emergency department arrival nearly doubled between 1992 and 1995. Based on these and other results presented at the 5-year juncture of the program, the NHAAP Coordinating Committee assessed progress and identified new areas of focus for the next 5 years. Improvements in emergency departments' ability to identify and treat AMI patients progressed during the first 5 years of the NHAAP, when the program was highlighting this as a priority. This model is continuing to be used to address delays in the Prehospital Action Phase. Further research from a National Heart, Lung, and Blood Institute (NHLBI) community intervention trial will guide the program in its plans for full-scale public education to address the Patient/Bystander Recognition and Action Phase.
