SMLR - Major Clinical Study Using Semler's QuantaFlo® for Medicare Advantage Beneficiaries Demonstrates that National In-Home Screening for Peripheral Artery Disease (PAD) is Feasible

PR Newswire

SANTA CLARA, Calif. , Dec. 14, 2022 /PRNewswire/ -- Semler Scientific, Inc. (Nasdaq: SMLR), a company that provides technology solutions to improve the clinical effectiveness and efficiency of healthcare providers, today announced that a study was published in the peer-reviewed AJPM Focus with data collected using the company's QuantaFlo® PAD test under real-world conditions, illustrating the benefits of PAD in-home screening. AJPM Focus is the official open access journal jointly launched this year by both The American College of Preventive Medicine and the Association for Prevention Teaching and Research. The article, titled " Peripheral Artery Disease Screening in the Community and 1-Year Mortality, Cardiovascular Events, and Adverse Limb Events ," ¹ may be accessed through this link: https://www.sciencedirect.com/science/article/pii/S2773065422000141#sec0015.

The study analyzed screening tests using QuantaFlo® for Medicare Advantage beneficiaries aged ?65 years participating in the Optum HouseCalls program in the U.S. between April 1, 2017 and February 1, 2019 . Of the 192,500 patients tested in their homes, 27.7% had a positive result for PAD. One-year all-cause mortality, 1- and 2-year major adverse cardiovascular events (MACE), and major adverse limb events (MALE) in the PAD positive patients were all significantly increased versus those patients who screened negative for PAD (p <.001). Moreover, the severity of the test results was associated with worse outcomes.

This study provides evidence for the feasibility of a nationwide PAD-screening program with QuantaFlo® for individuals aged 65 years and older to assess previously undetected PAD burden, which can enable further stratification of all-cause mortality, MACE, and MALE risk. The authors stated, "Detecting previously undiagnosed peripheral artery disease is a way to risk stratify a population that would benefit from further cardiovascular risk management."

"We believe this study supports the use of QuantaFlo® for PAD by customers who conduct in-home testing, which may drive further adoption by existing and new customers," said Doug Murphy-Chutorian , M.D., chief executive officer of Semler Scientific. "Still to come is the publication of a separate study of QuantaFlo® used to aid in the diagnosis of another cardiovascular condition besides PAD. This manuscript is currently in final review by the publisher."
