This bill would enact the California Interoperability Enforcement Act to regulate electronic health record vendors operating in California. The bill would require the office to review federal law and policy for opportunities to regulate electronic health record vendors and to establish an interoperability enforcement structure. The Legislature finds and declares the following: Although technology to enable interoperability exists, vendors still view the adoption of open interfaces as detrimental to their competitive advantage, and vendors sell bundled solutions or a system of devices with closed, proprietary interfaces. EHR vendors charge costs above and beyond the initial expense of implementing EHR systems and participate in information blocking and opportunistic pricing, taking advantage of the high cost of switching technologies, the lack of clarity on necessary future upgrades, and the costs to maintain the systems.
