Fair Isaac Corporation (NYSE:FIC) and IDX Systems Corporation(Nasdaq:IDXC) today announced that Parkview Health is using anintegrated solution that combines Fair Isaac Blaze Advisor rulesmanagement technology with IDX(R) Carecast(TM) enterprise clinicalsystem to deliver sophisticated decision management support forhealthcare providers across the organization.

The combined solution has enabled Parkview, a not-for-profit,community-owned network of eight northeastern Indiana hospitals, todevelop a series of expert business rules that improve the efficiencyand safety of medication ordering and administration. Parkview hasimproved medication turnaround time by an average of 43 minutes and isproviding its clinicians with valuable tools that support patientsafety and help prevent adverse drug events.

"At Parkview Health, we are focused on how we use healthcaredecision making to deliver trusted care and improve health in thecommunity," said Jerry Mourey, vice president of information systemsat Parkview Health. "Blaze Advisor and Carecast have proven to bevaluable technologies for the implementation of new decisionmanagement initiatives."

Carecast creates a comprehensive lifetime patient record byautomating the workflow of users and supporting clinical, financialand administrative processes. As the embedded rules managementcomponent of Carecast, Blaze Advisor provides a rules building enginethat enables healthcare organizations to develop tailored decisionsupport functionality that addresses the requirements of specialtyareas and patient safety initiatives. The use of expert rules allowsdoctors to make more informed decisions regarding care, to adopt bestpractices and to better understand the cause and impact of theirdecisions. Healthcare business managers gain the ability to controlrules and business policies, and to set actionable limits that areflagged when reached.

"IDX's adoption of Blaze Advisor provides Carecast customers withan extremely robust decision engine and rules management solution,"said Dr. Robert Abarbanel, senior director of product strategy forCarecast. "Working in conjunction with the entire Carecast clinicalsystem, Blaze Advisor rules management provides unmatched efficienciesin workflow, decision making and business processes."

Using Blaze Advisor, Parkview has implemented an expert rule thatflags pediatric patients and requires verification of medicationdosages based on the patient's weight. If the weight is not listed ordoes not correspond to the dose ordered, the system alerts thepharmacist to contact the patient's clinician to confirm the necessaryinformation. Rules are also used to calculate estimated creatinineclearance when ordering certain antibiotics or other drugs than canaffect kidney function; require potassium level verification forpatients receiving Digoxin or potassium supplements; and require INRverification for patients receiving warfarin.

"Blaze Advisor is increasingly being embedded as the decisionmanagement component within other enterprise software applications,such as IDX Carecast," said Carole-Ann Matignon, vice president ofproduct management for Enterprise Decision Management Technologies atFair Isaac. "The integration of Blaze Advisor within other softwaresolutions provides compelling value to businesses looking to combinetheir existing technology with the industry's most powerful rulesengine.
