Crossflo Systems Acquires Iameter Healthcare Quality Assessment Platform.

--- Expands Healthcare Product Offerings ---

SAN DIEGO -- Crossflo Systems, Inc., a Patriot Scientific company (OTCBB:PTSC), announced today that it has acquired the assets of Verras Medical, Inc. (dba Iameter) and the Iameter portfolio of data analysis software and programs. The assets will be utilized to expand the current healthcare data sharing and analysis capabilities of the company.

"This addition to our healthcare practice gives us a compelling solution to the recent federally mandated requirements to identify and optimize the quality of healthcare delivery," said Renney Senn, Crossflo's president. "Added to our data-sharing capability with CDX, we can provide capabilities that address multiple needs of the healthcare community, from both private hospitals and public agency perspectives. To capitalize on this rapidly growing opportunity we will be dedicating an increased portion of our sales resources to those opportunities."

Iameter provides a healthcare software program for hospitals and physician groups to assess the quality of care delivery against state and federal healthcare standards to help them realize quality improvements and reduced costs. Using a software tool called "Sherlock," Iameter effectively analyzes multiple levels of data for all inpatient diagnoses and procedures as well as outpatient surgery and delivers its conclusions in easily interpreted graphical output. Iameter staff then train designated hospital personnel to investigate the sources of clinical variations and potential inefficiencies using this data-mining tool.

Recently The Centers for Medicare & Medicaid Services (CMS) announced that for the first time the evidenced quality of care delivery will begin impacting the amounts healthcare providers are reimbursed for services provided to Medicare patients. "American healthcare will be transformed from a price-based to a value-based healthcare delivery system when purchasers and patients have access to reliable health information and can knowledgeably select and reward providers who demonstrate superior medical and service performance," predicted William Mohlenbrock, M.D., Iameter's former chairman and chief executive officer.

Dr. Mohlenbrock is a nationally recognized expert on measuring and improving medical quality and cost efficiencies. In 1983, he co-founded Iameter and developed the Acuity Index Method, a Severity Risk-Adjustment Tool used in assessing inpatient data as the basis for physician-directed, clinical quality improvements. He was also a co-founder of Crossflo to address the growing movement to share medical data as well as solve law enforcement and public safety and security data sharing challenges. Dr. Mohlenbrock remains a subject matter expert for Crossflo in the growing healthcare data sharing field.
