Allied World Assurance Company Holdings, AG (NYSE: AWH) today announced that Allied World North America, through a “Best in Class” relationship with Emerge Diagnostics, LLC (Emerge), will make Emerge’s Electrodiagnostic Functional Assessment - Soft Tissue Management (EFA-STM) Program available to Allied World’s Defense Base Act policyholders.

With soft tissue injuries as a leading driver of Defense Base Act claims and costs, Emerge’s EFA-STM Program is a bookend solution that provides employers with a non-discriminatory approach to determine if a work-related injury occurred within the course and scope of employment. After performing a baseline test, Emerge stores the unread data until a work-related injury is reported, in which case a post-incident test will be conducted and compared to the results of the baseline test. This comparison determines the nature, extent and age of the soft tissue injury and whether it relates to the reported incident. This diagnostic tool provides improved claims handling transparency, increased accuracy during diagnosis, enhanced patient care and rehabilitation. The EFA-STM program is portable for use overseas, convenient for medical personnel to administer and complies with Federal mandates.

Karen Marotta, Vice President at Allied World, commented, “We are extremely pleased to work with Emerge to bring our insureds this exciting technology. This will reduce lost productivity due to injuries of soft tissue claims, while improving diagnosis and treatment effectiveness.”

MaryRose Reaston, PhD, chief science officer and founder of Emerge Diagnostics, also commented, “Our EFA-STM program is a powerful tool in easing the strain and cost of soft tissue injury claims and creating better patient care and better outcomes for injured employees. Through this agreement, this unique and enhanced program will enable us to further expand the use of our technology outside of the U.S. and to new sectors of business.”
