Vivio^® supports population-level risk stratification in two ways. First, for patients with risk factors, Vivio diagnoses elevated filling pressures or heart failure before symptoms escalate and land the patient in the ER/in-patient setting. Second, Vivio combines the results of its test with the Kansas City Cardiomyopathy Questionnaire (KCCQ-12), which allows physicians to triage patients with heart failure from lower risk/lower symptomatology to high risk/high symptomatology. This triaging workflow ensures patients who need more advanced speciality care receive a timely referral before experiencing an acute utilization.
