Quest Diagnostics Incorporated , the nation's leading provider of diagnostic testing, information and services, announced today that its MedPlus healthcare information technology subsidiary has been recognized as the number one Document Management and Imaging (DMI) vendor in the 2006 "Top 20: KLAS Mid-Year Report Card." (©2006 KLAS Enterprises, LLC. All rights reserved.) This top ranking position marks the fourth time the company's ChartMaxx® product, an enterprise-wide electronic health record solution, has placed first in the KLAS mid-year report.

KLAS rankings are based on interviews with healthcare executives, professionals and clinicians at more than 4,500 hospitals and 2,500 clinics nationwide. The ratings are based on feedback received from current customers. ChartMaxx was ranked the tenth best solution out of 96 products for its ability to provide an immediate operational impact to hospitals. Additionally, 100 percent of MedPlus customer respondents indicated they would buy ChartMaxx again.

KLAS defines DMI products as those that provide the core capabilities of Scanning, Creating, Archiving, Workflow and validation of Electronically Stored Documents and Images (not clinical images).

"We're delighted our ChartMaxx solution achieved first place again in the KLAS report," said Richard Mahoney, Vice President, Healthcare Information Solutions at Quest Diagnostics and President of MedPlus. "The results demonstrate our commitment to listening to our customers and delivering a valuable solution that helps them improve patient care and maximize business performance."

Commentaries from healthcare executives collected by KLAS and viewable through KLAS Online or Platinum KLAS highlight ChartMaxx's value. "We have saved four times what we have invested to use the ChartMaxx system," said a KLAS survey respondent. Another survey respondent said, "The MedPlus support is superior. Whenever we call them we get an answer right away. That is wonderful from a vendor." Finally, another survey respondent said, "MedPlus is a very good company with which to do business. They listen to their end- users and try to provide the enhancements we request in a timely manner. They also do a good job of providing fair prices and reasonable charges for add-on modules and interfaces. The MedPlus executives are also accessible and responsive."

Today, MedPlus has more than 120 ChartMaxx systems installed in hospitals and clinics with 125,000 clinical and administrative users managing more than 400 million clinical and administrative documents for 15 million patients.
