Health care reform refers to changes made to improve the health care system, aiming to increase access, reduce costs, and enhance the quality of care. These reforms can involve new laws, policies, or programs that address issues like insurance coverage, patient rights, and the efficiency of health services. In many countries, health care reform seeks to ensure that all individuals have access to necessary medical services without facing financial hardship. Examples of reform efforts include expanding Medicaid, implementing Affordable Care Act provisions, and promoting preventive care to improve overall public health outcomes.
