The American College of Physicians (ACP) has long advocated for universal access to high-quality health care in the United States. Yet, it is essential that the U.S. health system goes beyond ensuring coverage, efficient delivery systems, and affordability. Reductions in nonfinancial barriers to care and improvements in social determinants of health are also necessary. This ACP position paper calls for ending discrimination based on personal characteristics; correcting workforce shortages, including the undersupply of primary care physicians; and understanding and ameliorating social determinants of health. The ACP calls for increased efforts to address urgent public health threats, including injuries and deaths from firearms; environmental hazards; climate change; maternal mortality; substance use disorders; and the health risks associated with nicotine, tobacco use, and electronic nicotine delivery systems in order to achieve ACP's vision for a better U.S. health care system.
