Ohio’s overdose death rates are among the highest in the country, with 4,854 overdose deaths in 2017, a rate of 44.1 per 100,000 people. The Ohio Department of Health (ODH) worked in the eight Ohio EMS Regional Physicians Advisory Board (RPAB) regions to increase use of ODMAP in those areas. In addition, ODH supported API connections and coordinated an effort to identify and facilitate best practices in higher-burden areas. ODH worked with key partners in behavioral health, public health, law enforcement, and EMS to create strategic plans that use ODMAP to provide key geographic data.
