About Us

transforming healthcare with evidence

Our mission is to improve the quality and value of healthcare through the use of evidence.

Hayes, Inc. is driven by a deep passion to improve the health – and therefore lives – of those we touch through the clients we serve. The realization that the well-being of countless people may depend on our efforts spurs each employee to deliver extraordinarily thorough, scrupulously researched reports and support.

Our clients, who include hospitals, healthcare systems, government agencies, health plans and employers, know they can count on us to be fiercely unbiased when analyzing the efficacy and value of medical technology and practices. It is at the core of our corporate DNA.

Founded in 1989 by Winifred S. Hayes, our proprietary Hayes Rating has become the industry’s benchmark. At Hayes, we have repeatedly seen proof that evidence-based, clinically sound processes improve both the quality and the cost-effectiveness of healthcare delivery while stimulating performance improvement.

Hayes’ focus on evidence-based assessments of health technologies underlies all aspects of our research and consulting activities. We evaluate a wide range of medical technologies and clinical programs to determine their impact on patient safety, health outcomes, resource utilization and return on investment. We also help our clients integrate evidence into their processes and decisions.
