Purpose: Peripheral artery disease (PAD), continues to be underdiagnosed and thereby untreated early in its progression, leading to unnecessary healthcare costs, and more crucially, unnecessary amputations. The early identification of this chronic condition enables patients to have access to a wider range of lower-cost and lower-risk therapies that can improve patient outcomes and save lives. The most traditional point-of-care testing requires the administration of a 15 to 30-minute test, specialized testing equipment, and time in already stretched clinical workflows. The purpose of this investigation was to analyze the efficiency of a new tool titled PADnet Xpress (Biomedix, Saint Paul, Minnesota) in diagnosing PAD.
Material and Methods: Sixty-one MIMIT Health patients with typical and atypical PAD symptoms were screened for PAD using PADnet Xpress to examine the efficacy of this tool. Fifty-five were Caucasian, 3 were Asian, and 3 were Latino. Forty-four of those tested were female, 17 male, and the median age of residents tested was 82.
PADnet Xpress supports bilateral, non-invasive physiologic studies by assessing the posterior tibial and anterior tibial/dorsalis pedis arterial distributions using volume plethysmography. The results are captured in tracings documenting the morphology of the recorded waveforms which indicate whether PAD is present.
Results: While only 5 of the 61 participants had a previous PAD diagnosis in their chart, 47 were identified as having PAD as a result of this initiative, or 77%. Of the abnormal studies, 81% had mild disease, 15% had moderate disease, and 4% had severe PAD. Of the 56 patients without a previous PAD diagnosis in their chart, 77% had an abnormal PAD test.
Conclusions: This investigation showcased the efficacy of using PADnet Xpress as a diagnostic tool for identifying PAD within non-symptomatic patients. Its low-cost, time-saving approach to diagnosing PAD has the potential to be adopted in primary care practices within regular check-ups. This innovative approach enables community-based collaborative care to optimize patient outcomes.
