The Impact of a Customized Price Transparency Tool on Consumer Behavior
We estimate the impact of tool availability on individuals’ provider choice, selected utilization outcomes, and costs using an instrumental variables approach. We distinguish across different “clinical patient cohorts” which we hypothesize to have differential gains from the price transparency tool. Our cohorts include pregnancy, back pain, knee pain, coronary artery disease, hernia, and individuals who seek annual preventive services. Although these conditions are not exhaustive they represent clinical conditions with important utilization and cost implications. They include services where utilization rates are highly variable across physicians and potentially over-utilized, since additional treatment is often not associated with improvement in clinical outcomes. Consequently, our study sheds light on the tool’s impact with respect to changes in provider choice, changes in potentially over- or underutilized services, and potential reductions in health expenditures. Payers are advancing greater price transparency as a vehicle for reducing health care expenditures. Our results inform for which patients this is most likely to be the case.
