Masimo reports positive data from SafetyNet study in Covid-19 patients

SafetyNet includes spot-checking and continuous measurements, remote patient surveillance, and digital care pathways.

Masimo has reported positive data from a two-part retrospective study of its remote patient management and telehealth solution, SafetyNet.

Masimo SafetyNet is a scalable, secure, Cloud-based patient management platform that has been designed to help healthcare providers remotely manage patient care.

It includes clinical-grade spot-checking and continuous measurements, remote patient surveillance, and digital care pathways.

Using the company’s tetherless Masimo Radius PPG SET pulse oximetry and a smartphone application, the system continuously sends home-based patient monitoring data to clinicians.

The study was designed to assess the impact of remote patient monitoring (RPM) using SafetyNet on hospital length of stay (LOS) in Covid-19 patients.

It was conducted by Dr Hemali Patel and colleagues at the University of Colorado in collaboration with UC Health (UCH), based in Aurora, Colorado, US.

Published in Telemedicine and e-Health, the findings showed that RPM using Masimo SafetyNet reduced hospital LOS for Covid-19 patients.

The study also demonstrated a significant association between briefer hospitalisation and patients discharged with the new RPM device and without home oxygen.

The researchers concluded that home telemonitoring of Covid-19 patients after discharge may be a safe tool to help reduce the mean duration of hospitalisation and create more capacity for beds at hospitals.

They implemented an RPM feasibility programme with SafetyNet (Phase I) at UCH during the first Covid-19 surge, from March to June 2020.

During the second surge (Phase II), from October 2020 to February last year, they redeployed the device.

The researchers remotely monitored pulse rate, plethysmographic respiration rate (Masimo RRp) and oxygen saturation (SpO₂) using Masimo SafetyNet with Radius PPG.

The data was transmitted through the company’s HIPAA-compliant secure Cloud service.

In total, 923 patients were enrolled in Phase I, with 78 discharged with SafetyNet and 845 without.

Phase II enrolled 1,056 patients. 125 were discharged with SafetyNet and 931 without.

In the study, the discharged patients with and without SafetyNet were compared using a two-to-one-matched case-control design.

The patients were matched in each phase depending on age, sex, Charlson comorbidity index and limited English proficiency.
