Cardiovascular and Respiratory Assessment Using Biometric Signals in a Non-contact Monitoring Device

An interventional study of CVInsight Monitoring in End-stage Renal Disease, sponsored by London Health Sciences Centre OR Lawson Research Institute of St. Joseph's. Terminated at 1 site in Canada. Per ClinicalTrials.gov, last updated 2021-08-19.

Why this study was terminated
Inability to demonstrate efficacy. The reason for this is that we were unable to get the necessary information from our population of dialysis patient using the mCVI™ non-contact facial tracking cell phone app.

Study summary

Patients on hemodialysis treatment experience increased levels of cardiovascular disease. In this study, investigators will be detecting hemodialysis induced circulatory stress using the CVInsight Patient Monitoring \& Informatics System - InteloMed. This system consists of the CVInsight non-contact device and the CVInsight contact device that measures a patient's response to dialysis by looking at many physiological parameters such as heart rate, heart rate variability, respiratory rate, and how much oxygen the blood is carrying. Investigators would like to validate the mobile CVInsight non-contact device to the currently used standard CVInsight contact device to provide healthcare providers with a better understanding of its role in early detection of cardiovascular stress induced by hemodialysis.

Read the detailed description

This observational validation trial involves patients from the prevalent dialysis population in London, Ontario. Investigators intend to validate the mobile CVInsight non-contact device to the standard contact version of this device for assessing hemodialysis induced circulatory stress. The CVInsight Patient Monitoring \& Informatics System records a patient's pulse waveform to determine a patient's response to dialysis and alerts to several physiologic changes including pulse strength, pulse rate, pulse irregularity, oxygen saturation, and oxygen saturation variability. The CVInsight contact and non-contact devices will be used for two study visits. The first study visit will be on the patient's first dialysis session of the week (after the weekend - 72 hour inter-dialytic period) and the second study visit will be during the patient's second dialysis session of the week (mid week - 48 hour inter-dialytic period). This will allow investigators to see if there is a difference between these two intervals of time. The investigators will also be using other gold standard methods of validating components of this device including myocardial stunning using the GE Healthcare Vivid q cardiovascular ultrasound system. The echocardiographic ultrasound machine and finometer will be used for two study visits to take place during the patients' regularly scheduled dialysis sessions. The first echocardiogram will be done prior to the initiation of dialysis and the second at peak dialysis stress, which is 15 minutes before the end of the hemodialysis treatment. In addition, the finometer will be used continuously throughout hemodialysis.Validating the mobile CVInsight non-contact device to the CVInsight contact device will allow investigators to observe the degree to which these devices are able to detect hemodialysis induced circulatory stress, which will enable the healthcare provider to detect injury early enough to intervene prior to its occurrence. This is important because hemodialysis and the accompanying stress it induces increases mortality significantly in this population of patients.

This study is investigator initiated and the study will continue until the investigators reach our target sample size.

Each patient will have two study visits. Patients on a Monday, Wednesday, and Friday schedule will have study visits on Monday and Wednesday of the same week and patients on a Tuesday, Thursday, and Saturday schedule will have study visits on Tuesday and Thursday of the same week.
