Mapping opportunities for healthcare improvement

IHA’s California Healthcare Cost & Quality Atlas measures healthcare performance across the state. The publicly available tool looks at clinical quality, hospital utilization, and cost of care metrics by geography for 30 million Californians.

The Atlas gives us a snapshot of where healthcare is performing well and where it’s not. And this visibility can lead to improved care and reduced disparities for Californians.
