study of adi cardiopulmonary management (cpm) system

Conditions: Heart Failure

Summary: this study is meant primarily collect cardiopulmonary management (cpm) data from daily usage and compare it to the clinical course of a patient. for this study, the only aspect of the cpm solution that will be used will be the device itself and the mobile application to assign devices to patients. the patients will be assigned a device at visit one and take the device home. they will use the device once daily (when they first wake up) for 6 months. the patient will come in for visit 2 to return the device.

patients that participate in this study will be using a wearable device for 6 months. at their initial visit (visit 1), patients will undergo a brief physical exam, have their medical history and medications recorded, and be fit to a device. with their clinical (or clinician delegate), the patient will have their baseline reading with the device. the patient will then be taught how to use the device at home and go through 2 practice patient-initiated measurements. the patient will also complete two surveys as a part of visit 1. these surveys can be done at the visit or at home within 7 days of the visit. details of all available history of chronic heart failure (chf) disease including surgical interventions related to chf, chf risk factors, or chf comorbidities will be recorded (via a chart pull after the visit). the number of previous chf-related hospitalizations, the patient's latest chf diagnosis classification, and date of last hospitalization (number of days since) will be specifically noted. this includes notes about the current condition of the patient and their congestion and fluid status. current new york heart association (nyha) classification will be pulled as well (or assigned during the physical exam portion). recent bnp (brain natriuretic peptide), creatinine, left ventricular ejection fraction (lvef), chest xray and other relevant labs will also be pulled from the chart and with vaccination status and dates for the following vaccines: covid 19, flu and pneumonia. this is the first chart review (of two) that is required for the study). after visit 1, the patient will use the device once daily for 6 months. after 6 months, the patient will return for visit 2. at visit two, the patient will have a brief physical exam and return the device. the patient will complete the same two surveys and an additional survey about their perception of the device. 30 days after visit 2 a second, targeted chart review will occur. details of the patient's clinical course while they were using the device and for an additional 30 days after will be recorded. while the chart review will be targeted to the chf clinical course (such as emergency room visits, hospitalizations, skilled nursing facility visits, outpatient checkups and other chf related notes), other relevant information will be collected as well. the most recent nyha classification will be pulled (or assigned at visit 2). the most recent bnp, creatinine, lvef, chest xray and other relevant labs will be pulled.
