On January 12 - 14, Peter Kreiner and John Eadie traveled to Sacramento, CA, at the request of the CA PDMP Administrator, Mike Small, to meet with Mike and PDMP staff, researchers from UC Davis, and representatives of the CA Department of Public Health and the CA Healthcare Foundation (CHCF), to discuss and plan for CHCF's production of opioid heat maps" for public consumption. Our role was to discuss our use of CURES (PDMP) data to produce measures for these maps. In subsequent email exchanges, we considered the utility of a number of PBSS measures for these maps.
