Wasco County Administrative Officer Tyler Stone and volunteer consultant Kathy Schwartz gave County Commissioners their plan for evaluating the North Central Public Health District.  Stone says the plan involves doing cost-benefit analysis of services, determining if the programs being offered are the correct ones in a changing health care world, and addressing the actual governance of the district.  That analysis is expected to take about six months.  District Director Teri Thalofer said evaluating return on investment in public health is difficult because that return doesn’t necessarily come back to local government and or public health but to society itself.  County Commission Chair Scott Hege says that needs to be considered, but he added the increasing costs of public health need to be looked at.  Schwartz, who as director of the Wasco County Health Department was part of the initial discussions for formation of the district that also includes Sherman and Gilliam counties, said she hoped a revised intergovernmental agreement for the district could be developed by November.  County Commissioners had voted to leave the district late last year, but rescinded that decision amid legal questions.
