FDA announces program to facilitate development of external defibrillators to treat abnormal heart rhythms

The U.S. Food and Drug Administration today announced a program aimed at facilitating the development of safer, more effective external defibrillators used to treat abnormal heart rhythms through improved design and manufacturing practices. External defibrillators are medical devices designed to diagnose life-threatening abnormal heart rhythms and treat them by delivering electrical energy to the heart to restore its normal rhythm. When used in the first few minutes following a cardiac arrest, they can save lives.

 External defibrillators are used successfully thousands of times each year to treat sudden cardiac arrest. Automated external defibrillators (AEDs) are found in public settings and increasingly in homes, airports and office buildings. More complex external defibrillators are used in hospitals by trained health care professionals. Nearly 300,000 Americans collapse each year when the heart stops pumping blood to the body (sudden cardiac arrest). Those who experience the condition may die if normal rhythms are not restored quickly. Survival depends on a rapid sequence of rescue events that can include the successful delivery of a high-energy shock from an external defibrillator.

 During the past five years, the FDA's Center for Devices and Radiological Health (CDRH) has received more than 28,000 medical device reports associated with the failures of external defibrillators and manufacturers conducteddozens of recalls involving hundreds of thousands of the devices. Many of the types of problems that CDRH has identified are preventable, correctable, and can impact patient safety. These problems include engineering design and manufacturing practices related to the adequate control of components bought from other suppliers.  

"These devices play an important role in health care," said CDRH Director Jeffrey Shuren, M.D. "The purpose of our initiative is to improve these technologies so we can save more lives." As a part of a broad initiative, CDRH is taking steps to work with manufacturers, users and experts in the field to improve the engineering design and manufacturing practices of these devices, and facilitate the development of their next generation.CDRH intends to release a white paper that describes the actions the Center is taking to improve the safety external defibrillators used today and to foster the development of safer, more effective technologies in the near future as part of its External Defibrillator Improvement Initiative. 

Goals of the initiative include: ·        

• Promoting the  innovation of next-generation external defibrillators to improve safety and effectiveness 
• Enhancing the ability of industry and the FDA to identify and resolve problems with devices currently on the market to address safety risks more quickly and effectively
 
• Designating an appropriate premarket regulatory pathway for AEDs that promotes best practices for design and testing.

 The initiative kicks off with a public meeting on Dec. 15-16, 2010, at the FDA headquarters in Silver Spring, Maryland where industry and other external stakeholder will discuss ways to improve these devices. The FDA is also collaborating with the University of Colorado's Department of Emergency Medicine to define the enhancements that will improve ease of use and outcomes, such as conducting a multi-city pilot of connecting AEDs with local emergency medical services so that when an AED is used an emergency rescue team is rapidly dispatched. For more information:
