Between March and June 2016, six California hospitals in the East Bay region (across from San Francisco) launched a data sharing initiative and coordination platform that provides emergency department physicians real-time notifications and shared plans of care for consumers who frequently visit emergency departments. The notice also provides health information, including behavioral health information. The initiative involves four hospitals run by Sutter Health and two public hospitals in the Alameda Health System. The goal is to reduce duplicate tests and procedures for people with chronic conditions related to homelessness, drug abuse or psychiatric issues, and link the frequent users . . .
