Masimo Corporation (MASI) Release: New Clinical Study Finds Pronto® Has Similar Accuracy to Commonly Used Point-of-Care Invasive Hemoglobin Analyzer


10/25/2012 1:56:13 PM

IRVINE, Calif., Oct. 24, 2012 /PRNewswire/ -- Masimo (NASDAQ: MASI) announced today that a new study published in Postgraduate Medicine demonstrates noninvasive total hemoglobin (SpHb®) measurements from the Pronto have an accuracy similar to those of the most commonly used invasive point-of-care (POC) hematology analyzer (HemoCue® 201+, Quest Diagnostics) in outpatient settings.1

Total hemoglobin (Hb) is one of the most frequently ordered laboratory tests in hospitals, urgent care centers, physician offices, and public health clinics.2 Anemia, defined as low hemoglobin concentration, is among the most common blood disorders in the United States, afflicting an estimated 3.4 million Americans, according to the National Center for Health Statistics. Many people are at risk for anemia because of poor diet, intestinal disorders, chronic diseases, infections, and other conditions. The signs and symptoms of anemia can be easily overlooked, and many people do not realize they have anemia until it is identified by a blood test.

Yet conventional invasive POC testing is time-consuming and exposes the patient and clinician to potential contamination and exposure to blood-borne pathogens. Errors occurring during the pre-analytical phase from the time the test is ordered by the physician until the sample is ready for analysis can account for up to 93% of the errors currently encountered during the total diagnostic process.3 A review of multiple studies in 2002 showed similarly high levels of errors.

The study that appears in Postgraduate Medicine, by Marina Raikhel, M.D., of the Torrance Clinical Research Institute in Lomita, Calif., measured hemoglobin of 152 subjects (69% women) presenting at an outpatient research clinic with common conditions such as diabetes, asthma, high cholesterol and high blood pressure.

Compared to laboratory analysis of blood, the bias ± standard deviation were 0.5 ± 1.0 g/dL for SpHb and 0.3 ± 1.0 g/dL for HemoCue 201+. Noninvasive SpHb testing had bias and standard deviation similar to those of HemoCue 201+, according to the study.

"Because SpHb mea­surement is noninvasive, it has the potential to confer the additional benefits of patient comfort, decreased complexity, and increased safety for health care providers who are not exposed to risks of needle-stick injury and blood-spill contaminations," the study concluded.

"As this study shows, the accuracy of the Pronto provides clinicians a powerful, yet painless, tool to test total hemoglobin without many of the risks associated with conventional, invasive testing," said Dr. Michael O'Reilly, Chief Medical Officer at Masimo. "The simplicity, safety and accuracy of the Pronto can help hospitals, clinics and physician offices improve processes and patient outcomes."

About Masimo
Masimo (NASDAQ: MASI) is the global leader in innovative noninvasive monitoring technologies that significantly improve patient carehelping solve "unsolvable" problems. In 1995, the company debuted Measure-Through Motion and Low Perfusion pulse oximetry, known as Masimo SET®, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced rainbow® SET Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb®), oxygen content (SpOC), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI). In 2008, Masimo introduced Patient SafetyNet, a remote monitoring and wireless clinician notification system designed to help hospitals avoid preventable deaths and injuries associated with failure to rescue events. In 2009, Masimo introduced rainbow Acoustic Monitoring, the first-ever noninvasive and continuous monitoring of acoustic respiration rate (RRa). Masimo's rainbow SET technology platform offers a breakthrough in patient safety by helping clinicians detect life-threatening conditions and helping guide treatment options. In 2010, Masimo acquired SEDLine®, a pioneer in the development of innovative brain function monitoring technology and devices. Masimo SET and Masimo rainbow SET technologies can be also found in over 100 multiparameter patient monitors from over 50 medical device manufacturers around the world. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care... by Taking Noninvasive Monitoring to New Sites and Applications®."
