GE HealthCare has announced the publication of two-phase pilot study data regarding the use of its Portrait Mobile monitoring solution in post-surgical wards environment.
The COSMOS study, conducted in partnership with Cleveland Clinic, highlighted the effectiveness of this wireless, wearable monitoring solution in encouraging clinical intervention while reducing alarm fatigue.
The Phase 2 pilot study enrolled 150 post-surgical patients, who were randomised into two groups. One group received routine vital signs assessments, and the other underwent continuous monitoring of respiratory rate, oxygen saturation, and pulse rate with Portrait Mobile.
Key findings from the study include patients in the Portrait Mobile group who had an average of less than three alarms per day. Clinicians found 82% of the Portrait Mobile alarms to be informative or useful.
GE HealthCare said these alarms played a key role in clinical decision-making, with the most common nursing intervention being the initiation or adjustment of oxygen therapy administered to a patient.
Precisely, clinicians administered oxygen to 60% more patients in the Portrait Mobile group compared to those with intermittent monitoring.
Overall, continuous monitoring and alerts with Portrait Mobile led to around 25% reduction in vital sign abnormalities.
Following the completion of the COSMOS pilot, a full clinical trial is now underway.
GE HealthCare patient care solutions chief medical officer John Beard said: “In the ward environment where bedside clinicians are responsible for multiple patients simultaneously, care should be focused on the patients who need it most, and this requires ongoing surveillance and communication.
“Continuous physiologic monitoring solutions can meet the challenge to alert care teams for changes in patient status but must be properly configured to optimise actionable alarms and clinical value.
“These research findings demonstrate that Portrait Mobile can meet the needs of patients and clinicians and provide critical information to support clinical decision making without causing undue burden.”
Portrait Mobile is part of GE HealthCare’s FlexAcuity monitoring solutions, designed to adapt quickly to changing patient needs.
The monitoring solution secured the US Food and Drug Administration (FDA) clearance in August 2023.
GE HealthCare also has Portrait VSM vital signs monitor in its portfolio, which was cleared by the FDA in April this year.
