SANTA CLARA, Calif., March 1, 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 a study was published on-line as a pre-proof in the peer-reviewed Journal of Vascular Surgery with data collected using QuantaFlo® under real-world conditions.

The article, "The Nevada Peripheral Artery Disease Screening Effort in a Medicare Advantage Population and Subsequent Mortality and Major Adverse Cardiovascular Event Riskⁱ," may be accessed through this link: https://doi.org/10.1016/j.jvs.2022.01.134.

The study analyzed screening tests using QuantaFlo® for undetected and asymptomatic peripheral arterial disease (PAD) in a Medicare Advantage population with three-year follow up. In this study, 13,971 patients were tested and 31.6% had a positive result for PAD. The large metropolitan area was characterized by concentrations of atherosclerotic risk factors along with a more vulnerable socio-economic risk profile. The risk associated with detecting PAD was substantial with a 60-70% increased risk of all-cause mortality or morbidity at one year and a 40-50% increased risk of all-cause mortality or morbidity at three years. The association of risk at three years was not modified following multivariable adjustment (p <.001).

The study's take home message: "A positive screening result of previously undetected lower extremity PAD was independently associated with short-term and long-term increased risks for mortality and major adverse cardiovascular events (MACE) in individuals aged 65 years and older living in a large, metropolitan area."

The authors stated that these findings in a Medicare Advantage population prospectively screened for previously undetected PAD, a positive PAD screen was significantly associated with subsequent excess mortality and MACE risk, underscoring the potential for PAD risk management at the population level.

"We believe this study supports the use of QuantaFlo® and the benefits that early screening for PAD brings patients and the health providers that care for them," said Doug Murphy-Chutorian, M.D., chief executive officer of Semler Scientific. "The study may drive further adoption of QuantaFlo® by existing and new customers."
