|Use of Quidel QuickVue(R) Rapid Flu Test in Nursing Homes Allows for More Rapid Recognition of Outbreaks and Appropriate Therapies|
Outbreak Duration and Incidence Rate Lowered in Study Facilities
SAN DIEGO--(BUSINESS WIRE)--Oct. 8, 2007--Quidel Corporation (NASDAQ:QDEL), a leading provider of rapid point-of-care (POC) diagnostic tests, announced today that a poster presentation at the Infectious Diseases Society of America 45th Annual Meeting (October 5, San Diego) indicated the on-site use of rapid influenza tests allows for the early detection of influenza, more timely treatment of residents (patients), and improved management of respiratory outbreaks in nursing home facilities.
The study, entitled "Active surveillance and Point-of-Care testing (POCT) allows early intervention for influenza outbreaks in nursing homes," was presented by Dr. Dominic Dwyer, MD, FRCPA, of the Centre for Infectious Disease and Microbiology Laboratory Services, ICPMR, Westmead Hospital, Australia. Dr. Dwyer reported on the results from the first two years of an ongoing three-year study. During this period, there were six confirmed influenza outbreaks in the nursing homes. A comparison of outcomes at nursing homes receiving active surveillance with rapid tests and intervention with antivirals versus those with routine self-reporting of outbreaks (with no rapid tests) showed a significant difference in outcome. The attack rate of residents was reduced from 42% to 21%, the time between initial outbreak and intervention with antivirals was reduced by almost 50%, and the duration of the outbreak within the nursing homes was reduced from an average of 22 days to 11.5 days.(1) Dr. Dwyer concluded that "the QuickVue test for influenza performed by nursing home nurses on-site is sensitive and highly specific and allows for rapid recognition of outbreaks and (timely) intervention with antiviral therapy."
"I congratulate Dr. Dwyer on his work with the elderly nursing home population," said Caren Mason, president and CEO of Quidel. "The significant reductions in resident attack rate, and in the duration of the nursing home outbreaks, support the notion that active surveillance with rapid tests coupled with timely intervention with antiviral therapy can have a major impact on health outcomes for these elderly patients. This is particularly important when considering the fact that approximately 90% of the 36,000 persons who die from influenza each year in the United States are among the elderly."(2)
According to the Centers for Disease Control (CDC), influenza is responsible for about 36,000 deaths and more than 200,000 hospitalizations in the U.S. each year. The National Foundation of Infectious Diseases, in a report released in September 2007, indicates that influenza can be especially severe for those with high-risk conditions (e.g., diabetes and heart disease), and recent studies have also found that the illness may trigger up to 92,000 cardiac deaths per year nationwide.(3)
