Ep3-Who Knew? What Health Departments Do
A health department in Kentucky pays half your rent. Another in Oregon runs the county jail's medical system. A third in Iowa partners with businesses to raise wages for childcare workers.
How did we end up with a public health system where one department operates comprehensive medical clinics while another struggles to conduct timely septic inspections?
Let’s investigate the 4 categories of work that state and local health departments choose from when planning their activities: foundational services (disease response and restaurant inspections), clinical care for low-income residents, social determinants of health (housing and nutrition), and health strategy (coordinating all the pieces of a community's health infrastructure).
Most local public health departments don't do all four. Some can barely manage one. The variation is staggering.
Regardless, all public health agencies are better off when they find community-based partners to collaborate with and engage regularly with their residents… Even better when they can prove their efficacy, quantify the return on investment, and explain why they take actions that might well be unpopular.
