Our analytical tool measures low-value care and pinpoints sources of wasteful spending.

An estimated 30 percent of US health spending is wasted, much of it on low-value services. And while the problems of low-value care are widely recognized, clinicians, administrators, and policymakers across the country still find it difficult to measure the extent of waste in the system or identify the most significant opportunities to reduce low-value services. PROMETHEUS Value addresses this need.

Our Approach

PROMETHEUS Value measures the total burden of low-value care in a population and helps users pinpoint sources of inefficiency. The tool encompasses multiple domains of health care inefficiency and waste, including: 1) overused services; 2) the use of high-priced professional and facility services when a lower-priced identical service or better alternative is available; 3) services used to treat potentially avoidable complications; and 4) the absence of high-value care.


Health plans, employers, Medicaid programs, and health systems can use PROMETHEUS Value to measure the total burden of waste in their systems and track trends over time; drill down within specific domains of low-value care to identify the services that contribute the most to the total burden; and tailor policy solutions that effectively eliminate the primary drivers of low-value care and inefficiencies in a specific population.
