On March 27-28, 2018, Dr. Noam Arzt, President of HLN, participated by invitation in the Stewards of Change National Interoperability Collaborative Symposium on Advancing Information Sharing in California and Beyond on behalf of the Healthcare Information and Management Systems Society (HIMSS). In attendance was a small, but diverse set of stakeholders across the health, human services, education, and criminal justice with an interest in improving data interoperability between systems with these diverse domains, with a special emphasis on efforts in California. Sponsored by the National Interoperability Collaborative (NIC) this symposium represents a continuing expansion of the Stewards of Change focus from human services into the health domain. This expanded conversation will allow public health to participate more fully as the shift to our collective concern about wellness requires a more holistic view of people, their requirements, and their circumstances. We look forward to continuing engagement with this community and an opportunity to bring what we have learned in public health about interoperability into this new forum.
