Health Professional Shortage Areas (HPSAs) are regions identified by the U.S. government where there is a lack of healthcare providers. These areas may have insufficient numbers of primary care physicians, dentists, or mental health professionals, making it difficult for residents to access necessary medical services. HPSAs can be designated based on geographic location, population groups, or specific facilities. The designation of HPSAs helps direct resources and funding to improve healthcare access. Programs like the National Health Service Corps aim to recruit and place healthcare professionals in these underserved areas, ensuring that communities receive the care they need to maintain their health and well-being.
