The Peterson-KFF Health System Tracker is an online hub monitoring how well the U.S. health system is operating through key quality and cost measures. A partnership of the Peterson Center on Healthcare and KFF, the Tracker documents trends in Health Spending, Quality of Care, Access & Affordability, and Health & Wellbeing through issue briefs and downloadable chart collections. The Tracker also includes the Interactive Health Spending Explorer tool, which helps users analyze more than 50 years of health expenditure data, and a Health System Dashboard, which provides quick and easy access to the latest, most relevant statistics.
