News Release Details

PLANO, Texas and BURLINGTON, N.C., Jul 21, 2003 /PRNewswire-FirstCall via COMTEX/ -- The Patient Safety Institute (PSI) a leader in patient information, safety and healthcare connectivity, and Laboratory Corporation of America(R) Holdings (NYSE: LH) (LabCorp(R)), a pioneer in commercializing new diagnostic technologies, announced today an agreement to work together to provide clinical laboratory results to physicians via PSI's secure, patient-centered, point-of-care information system (PSI System). Initially, the alliance will focus on providing this capability to physicians in Delaware as part of the first statewide clinical information sharing utility, which was announced on July 8th. PSI's Supporting Partner, Medicity Inc, will play a key role in providing technology to the partnership and in facilitating the Delaware initiative.

The goal of this alliance is to ensure that all physicians who participate in the PSI System, beginning with the Delaware network, have access to updated laboratory results for patients who grant permission for sharing of their data.

LabCorp maintains a nationwide network of state-of-the-art medical testing laboratories and offers more than 4,000 clinical tests. Laboratory test results, like those provided by LabCorp, influence thousands of critically important decisions made by patients, doctors and other health care professionals each day. By virtue of its broad range of capabilities, LabCorp goes well beyond the traditional role of a clinical lab, and acts as an active partner in enabling medical professionals to leverage the latest diagnostic technology to help preserve patient health and improve quality of life.

"LabCorp shares PSI's vision for improving the quality of clinical care, reducing cost and enhancing customer service for all participants in today's health delivery system," said LabCorp Executive Vice President for Sales and Marketing, Stevan R. Stark. "By remaining committed to embracing new technologies that improve clinical information access, LabCorp seeks to provide the highest quality test ordering and results reporting solutions possible for doctors who need the information in real time. This exciting new partnership with Patient Safety Institute allows LabCorp to increase physician access to critical information at the point of care."

PSI is dedicated to improving healthcare quality and reducing healthcare costs by providing, upon consent of the patient, real-time access to clinical information for patients, hospitals and physicians at the point of care. Under a national collaborative governance model, patient, physician and hospital leaders have come together to create a trusted third party that can harness the power of emerging technology and apply it to the sharing of clinical information.

"The ability to incorporate test results from LabCorp into the PSI Network is crucial to physicians who rely on this information for making patient care decisions," said Johnny Walker, CEO of PSI. "Working with our partner, Medicity Inc, we are able to quickly incorporate this functionality for the Delaware statewide network."

"The alliance between LabCorp and PSI brings an important capability to the Delaware statewide PSI network," said Kipp Lassetter, MD, CEO of Medicity Inc. "As the physician portal partner for the Medical Society of Delaware, Medicity is pleased to be able to help facilitate this important relationship."

"The partnership of PSI and LabCorp advances the Medical Society of Delaware's goal of improving patient care through real-time statewide clinical information sharing," added Mark Meister, Executive Director of the Medical Society of Delaware. "Improved access to critical information at the point of care is an important part of Delaware physicians continuing desire and quest to provide higher quality medical care in the most efficient manner."
