Abstract:

In this paper we investigate the relationship between the DRG system for hospital reimbursement and investment in technologies. We use a simple economic model where the reimbursement policy for treatments whose provision requires a sunk investment cost has an impact on both the decision whether to adopt the technology and many patient to treat with it. The optimal pricing policy involves a two-part tariff: a price equal to the marginal cost of the patient whose benefit of treatment equals the cost of provision, and a separate payment for the partial reimbursement of capital costs. Departures from this scheme, which are frequent in DRG tariff systems designed around the world, lead to a trade-off between the objective of making effective technologies available to patients and the need to ensure appropriateness in use.
