Health reform refers to changes made to improve the healthcare system, aiming to enhance access, quality, and affordability of medical services. These reforms can involve new laws, policies, or programs designed to address issues like rising costs, inadequate coverage, and disparities in health outcomes among different populations. One notable example of health reform in the United States is the Affordable Care Act, which was enacted in 2010. This legislation aimed to expand health insurance coverage, protect patients with pre-existing conditions, and promote preventive care, ultimately striving to create a more equitable healthcare system for all citizens.
