What do we know about rate-setting?

Area of Science:

• Health economics
• Healthcare policy
• Public health

Background:

• State regulation of hospital revenue is a proposed method for healthcare cost containment.
• Extensive data exist from state-level implementation, but findings are often complex and contested.
• Both proponents and opponents of rate-setting cite evidence to support their claims.

Purpose of the Study:

• To summarize and evaluate the empirical evidence on state-level hospital revenue regulation.
• To assess the effectiveness of mandatory rate-setting in controlling hospital costs.
• To compare the potential of rate-setting versus market-based approaches for cost containment.

Main Methods:

• Systematic review and synthesis of existing evaluative data on state rate-setting programs.
• Analysis of data from the "laboratory of the states" to assess cost containment outcomes.
• Comparative analysis of regulatory approaches versus market competition and selective contracting.

Main Results:

• Mandatory rate-setting has generally demonstrated success in constraining hospital costs in states where it has been implemented.
• The extrapolation of these results to additional states is uncertain.
• The comparative advantage of rate-setting over increased competition and selective contracting for overall healthcare cost containment is unclear.

Conclusions:

• While state rate-setting can constrain hospital costs, its broader applicability and superiority over market-based solutions require further investigation.
• Future policy decisions should consider the mixed evidence and the potential impact of alternative strategies like competition.
• The ambiguity of existing data necessitates careful consideration when evaluating the role of regulation in healthcare cost containment.
