Washington State Common Measure Set for Health Care Quality and Cost

What is the Common Measure Set?

The Washington State Common Measure Set for Health Care Quality and Cost is a set of measures that enables a common way of tracking important elements of health and health care performance and is intended to inform public and private health care purchasing of health insurance benefits. It helps determine how well the health care system is performing and will enable a shared understanding of areas that should be targeted for improvement. The measures focus on access, prevention, acute care, and chronic care.

Common Measure Set results

Who developed the Common Measure Set?

Based on legislation passed in 2014 (ESHB 2572), a statewide performance measurement committee was appointed by Governor Jay Inslee to oversee creation of the performance measures set. Three technical workgroups, which included representatives from health research, medicine, behavioral health, insurance plans, public health, health care practices, consumer groups, minority populations and the business community, researched and recommended health and health care quality measures for inclusion in the Common Measure Set.

How are the measures collected and reported?

The Washington Health Alliance (Alliance), a private nonprofit organization in the state of Washington dedicated to improving health care transparency, publishes results for the Common Measure Set. The Common Measure Set relies on two categories of data to produce results:

  • The Alliance maintains a robust database that includes health care claims and encounter data and reflects care provided to millions of people in Washington.
  • Results for some measures in the Common Measure Set are provided by partner organizations, including the Washington State Hospital Association, the Washington State Department of Health, the Washington State Department of Social and Health Services, the Washington State Health Care Authority and the National Committee on Quality Assurance.

Improving care, reducing variation

Variation in health care delivery among doctors and hospitals can be an important signal of poor quality. In a highly functioning health care system, everyone would receive a similar high level of evidence-based care for the same condition. However, we know this is not the case in Washington and elsewhere around the country. An important first step in reducing variation is measuring it and sharing results to develop a clear understanding of what needs to improve. The Common Measure Set enables a shared way of tracking health and health care performance. The Common Measure Set sends a clear market signal about expected performance and provides an opportunity for everyone to be measured in the same way across the state.

Why does Washington need its own measure set?

Having broad agreement around a Common Measure Set for Washington helps to focus and align efforts by key stakeholders to address specific opportunity areas in our state. National information provides important guidance and, in fact, the use of nationally agreed upon measures of health care quality is a priority here in Washington. However, it is at the state and community levels where change occurs. We select measures that target and help us address problems here in Washington. 

Future plans for the Common Measure Set

It's expected that the Common Measure Set will evolve over time to address the health and health care priorities of the state.
