TETERBORO, N.J., Feb. 6 /PRNewswire-FirstCall/ -- Quest Diagnostics Incorporated , the nation's leading provider of diagnostic testing, information and services, announced today that its MedPlus subsidiary was recognized for the second consecutive year as the number one document management and imaging (DMI) vendor for its ChartMaxx(R) enterprise-wide electronic patient record (EPR) solution in a study released by KLAS Enterprises. MedPlus develops state-of-the-art connectivity solutions, which provide physician and hospital customers with access to essential healthcare information at the critical point of decision making.

KLAS defines DMI vendors as those whose products offer the ability to "generate electronic forms, handle COLD (computer output to laser disk) feeds, store and retrieve data in its structured or unstructured form, provide simultaneous access to multiple users, integrate with actionable processes, monitor status tracking and/or workflow engines" and act as an "integral tool for retrieving data from disparate systems." MedPlus originally received the top ranking in February 2002, and has maintained its first place position since that time.

"The prestigious KLAS ranking demonstrates what MedPlus customers have known all along -- that ChartMaxx lets hospital administrators and admitting physicians effortlessly access and act on critical healthcare information to improve patient care and enhance efficiency," said Surya N. Mohapatra, Ph.D., President and Chief Operating Officer of Quest Diagnostics, the parent company of MedPlus. "We are committed to the continued success of MedPlus and ChartMaxx in the healthcare market."

MedPlus received higher scores than other suppliers including McKesson, Eclipsys, Siemens, LanVision, AMS and QuadraMed, based on responses and feedback received from current MedPlus customers. Among the 18 categories identified in the study, MedPlus placed first in 17 categories including "money's worth," "lived up to expectations," "commitment to technology," "product worked as promoted," "implementation on time" and "within budget."

Norm Swaton, Regional Director at KLAS Enterprises, said, "MedPlus continued to demonstrate high client satisfaction throughout 2002 as reported by consistently high marks provided by its customers. The top ratings of MedPlus and confidential interviews conducted by KLAS for all vendors show that ChartMaxx customers are genuinely pleased with many aspects of MedPlus' performance compared to competitors' products."

MedPlus has continued to add to the user and document count included in ChartMaxx and has realized dramatic increases since December 2001. The number of clinical users has more than doubled to 25,000 and the number of overall users, including administrative and clinical users, has nearly doubled to more than 50,000.

ChartMaxx has more than 178 million clinical and administrative documents stored in the system for 8.3 million patients.

MedPlus will provide demonstrations of the ChartMaxx product, the eMaxx(R) physician portal solution, and the OptiMaxx(R) document management system at HIMSS in booth number 5025 during established business hours at the San Diego Convention Center, Monday, February 10 through Thursday, February 13.
