As time goes on, the shortage of physicians is increasing. Demand is exceeding supply due to an aging population as well as the long training times involved in getting new medical students their degrees. The raw capacity of medical schools is also limited.
Because of this, the medical industry has had to adapt. Procedures that were once done by doctors are being performed by Advanced Practice Providers (APP) like nurse practitioners, physician assistants, and certified nurse registered anesthetists. Currently, there are about 234,000 advanced practice registered nurses in the United States, and the number is expected to grow.
