(De)constructing 'basic' benefits: citizens define the limits of coverage.

Many initiatives for covering the uninsured call for "basic" health care coverage, yet few define that term. The Just Coverage project used a computer-based simulation exercise to learn how nearly 800 community members in northern California identified the inclusions and exclusions that would constitute basic coverage. Working with a limited budget, participants distinguished essential from nonessential health care needs, resisted high patient cost sharing, and tolerated tight restrictions on provider choice. They also supported practice guidelines and standards of effectiveness, and they excluded high-cost, low-value interventions. These results reinforce the importance of community input to policymakers.
