IMPAC Oncology-Specific EMR is First to Interface With OTN Lynx Mobile(TM)
IMPAC and OTN Alliance Brings New Capability for Easy, Reliable Inventory Management and Reporting

SUNNYVALE, Calif., April 9 /PRNewswire/ -- IMPAC Medical Systems, Inc.
(IMPAC), an Elekta company and the world's leading provider of information
technology (IT) solutions for oncology care, announced today the first ever
live interface between an oncology-specific electronic medical record (EMR)
and OTN's Lynx Mobile(TM) software. IMPAC's oncology-specific EMR offers
patient charting and several advanced practice management capabilities, all
centralized in a single-database.

IMPAC's single-database EMR manages information related to scheduling,
billing, laboratory information systems, clinical charting for assessments,
encounters, chemotherapy regimens, automated drug calculations,
computerized physician order entry, and real-time data visualization to
support the unique oncology workflow. Lynx Mobile, developed by OTN, is an
automated charge capture, inventory management and reporting tool
specifically designed for community-based clinic staff to efficiently
manage inventory of drugs and supplies while improving the management of
clinical practice revenue. The interface of IMPAC's and OTN's powerful
oncology workflow management systems helps clinicians and cancer teams
significantly enhance workflow efficiency and patient experience.

Specifically, Hinsdale Hematology Oncology Associates, Ltd. (HHOA), a
Hinsdale, IL six-physician practice that provides services to 80-100
patients a day, has seen increasing patient loads since installing IMPAC in
2001. HHOA's investment in IMPAC allowed the clinic to transfer paper
charts to IMPAC's single-database EMR. Moving to the EMR enabled HHOA to
increase the speed and accuracy of the patient encounter, and enhance
patient documentation. As a result, HHOA enjoyed improvements in patient
and clinician satisfaction, patient load increases, and an elevated level
of process efficiency that essentially returned the EMR investment within
two years of implementation.

"The IMPAC EMR interfaced to the Lynx Mobile is convenient, easy to
use, and closely matches the workflow in our practice. It allows us to
capture lost charges on the system and gain data and information to help
run our practice," said Michele K. White, practice administrator and
operations manager for HHOA. "We have found that the IMPAC and Lynx Mobile
interface is vastly better than our previous interface. Now that we have
IMPAC's oncology IT solution and OTN's interface in place, patient
information is automatically transferred between IMPAC and Lynx Mobile.
This automatic updating of our IMPAC EMR saves time by eliminating manual
re-entry of patient data and patient charges."

"Our oncology customers are signing up to use Lynx Mobile because of
its ability to help them decrease lost charges and manage inventory in a
way that allows clinics to run as efficiently as possible," said Gena Cook,
vice president of sales and marketing for OTN. "This is a testament to the
technological advance that Lynx Mobile represents and further illustrates
how OTN differentiates itself from other distributors in the marketplace.
We believe Lynx Mobile's intuitive user interface and accessibility
anywhere in the clinic changes the way community-based infusion clinics
manage their patient care and work flow. With Lynx Mobile, practices have
more time to focus on delivering optimal patient care."

"IMPAC is pleased to have the opportunity to continue our work as OTN's
preferred oncology EMR vendor," states Barbara Robbins, Director, IMPAC
Medical Systems, Inc., Medical Oncology Business Unit. "This interface
facilitates the exchange of information between the IMPAC single database
EMR and practice management system to Lynx Mobile, which can further
enhance oncology workflow efficiency and accuracy."

Demonstrations and full details about the IMPAC oncology-specific IT
solution and the interface to the OTN Lynx Mobile will be available at the
AOHA Conference in Austin, TX, Booth # 18, April 15 - 17, 2007.
