Advocacy forms the core of many AHA initiatives, and the organization spreads its advocacy efforts across several fields. It encourages the funding of teaching hospitals, pushing legislators to expand monetary assistance to these essential training grounds for the next generation of medical personnel. It also advocates for the strengthening of Medicare and Medicaid programs, which provide a safety net for those who would otherwise be unable to access the medical care they need. The AHA works to strengthen clinical integration as well, making it easier for physicians and other medical personnel to care for patients across multiple providers and settings. Finally, the AHA encourages improvements in quality of care and overall patient safety, both by giving member organizations the tools they need to succeed and working with lawmakers to provide a favorable environment for patient health.
