LMS Shoulder Screen Licensed by TriState Medical Insurance Company

Montreal, Quebec, September 11th, 2006 – LMS Medical Systems (AMEX:LMZ; TSX:LMZ), a healthcare technology company and developer of the CALMTM clinical information system and risk management software tools for obstetrics announced today that within the framework of its obstetrical risk reduction strategy, Tristate Medical Insurance Company, RRG (TriMed) has licensed CALM Shoulder ScreenTM for use by OB providers.

Shoulder Screen, a web based proprietary risk management tool, assists clinicians to determine if their patients are at risk for Shoulder Dystocia prior to the onset of labor. The CALM Shoulder Screen was developed specifically to identify the highest risk cases associated with permanent injury.

TriMed has recognized that obstetrics represents a high potential for risk within its underwriting base and shoulder dystocia itself is one of the top causes of medical and legal risk within the specialty. This prompted TriMed to launch a shoulder dystocia risk management initiative for insured physicians that includes CALM Shoulder Screen. “We have licensed CALM Shoulder Screen directly for some of our Ob/Gyn insured physicians to help manage this problem” said William Michael McCullough, MD, FACOG, TriMed Board of Directors member and Managing Partner of one of the selected Ob/Gyn practices to implement this unique program. “We believe that a standardized approach to risk assessment will contribute to higher quality care.”

Shoulder Dystocia occurs when the baby’s shoulder gets stuck behind the mother’s pubic bone during delivery. Generally viewed in the medical community as unpredictable and unpreventable, Shoulder Dystocia is one of the most feared conditions that can occur during labor and delivery. Potential injuries include brachial plexus impairment, brain damage and sometimes death, with associated medical malpractice payouts ranging from $500,000 to $2M.

“In the economics of shoulder dystocia, physicians and physician insurers are among the stakeholders with the greatest exposure” said Diane Côté, CEO of LMS. “We are pleased that TriMed recognizes the opportunity to increase patient safety through the implementation of LMS’ risk reduction strategy.”
