Evaluating the Impact of Value-Based Purchasing: A Guide for Purchaser

A Guide for Purchasers

As purchasers of much of the health care in the United States, employers could be a powerful force in closing the gap between the quality of care that we have and the quality of care we should have. Many employers are developing strategies aimed at improving the quality and value of the health care they purchase. However, we have little evidence on the impact of such efforts.

Employers and coalitions need tools to help them track and assess the impact of their efforts in "real time." That way, they can determine quickly what works best and how to fine-tune their strategies.

This guide was developed to be an evaluation tool for purchasers, particularly employers, in assessing their value-based purchasing activities. It was developed for a meeting sponsored by the Agency for Healthcare Research and Quality (AHRQ), "Understanding How Employers Can Be Catalysts for Quality: Insights for a Research Agenda," held April 4, 2001.
