Academic Interests

Dr. Ruhnke is interested in the relationship between health system capacity and the value of health care services. High-capacity regions experience greater intensity of utilization without improved outcomes. As physician supply and imaging infrastructure expand dramatically, the value of discretionary services that become common with heightened capacity must be clarified. Dr. Ruhnke’s research is also using novel conjoint analysis methods to understand the mechanisms by which regional capacity impacts physician decisions, and resource utilization, at the provider level.
