摘要

Health care cost is the central measure to gauge the impact of UnitedHealth Group's (UHG's) provider rating tool. To investigate the impact of provider ratings on cost, we completed a claims-based analysis using data from UHG. The unit of analysis was continuously enrolled health plan participants over two years. Individuals were chosen based upon the deployment of the provider rating tool within a specific UHG geographic market. Currently, UHG has full claims data available for over forty million subscribers in markets that span the United States. In most markets, UHG has approximately 20% (on average) of the eligible enrollees. To answer research questions the authors used a quasi-experimental design where they tracked the health care cost and utilization of a specific subscriber and dependents over a two-year period from 2005 to 2006. The tool was not available to consumers in 2005, so this serves as the pre-tool base year. However, UHG collected information that enabled us to create provider rankings for 2005 and thus to calculate a difference score described below. In 2006 the tool was introduced in selected markets, and it was introduced in more markets in 2007. Data for the study came from two large employers with over 8,000 covered lives where all of the insurance contracts are managed by UHG. The authors had access to medical and pharmacy claims and enrollment data for two years: pre- and post-exposure to the provider ranking system.
