Accountable Care Organizations (ACOs) are groups of healthcare providers, such as doctors and hospitals, that come together to deliver coordinated care to patients. The goal of ACOs is to improve patient outcomes while reducing healthcare costs. By working collaboratively, these organizations aim to ensure that patients receive the right care at the right time, minimizing unnecessary tests and procedures. ACOs are often part of government programs like Medicare, which incentivize them to focus on quality rather than quantity of care. When ACOs successfully manage patient care and reduce costs, they can share in the savings generated, promoting a more efficient healthcare system.
