Insights
The COSMOS pilot study reveals significant potential for GE HealthCare's Portrait Mobile monitoring solution in post-surgical care. Key findings demonstrate 82% of alarms were clinically meaningful with less than 3 alarms per patient daily - a remarkably low rate compared to hundreds in critical care units.
The solution showed concrete clinical benefits: 60% more oxygen therapy interventions and a 25% reduction in vital sign abnormalities through early detection. This addresses a critical healthcare need, as post-surgical complications contribute significantly to global mortality rates.
For investors, this represents a strong market opportunity in the growing remote patient monitoring space. The positive clinical outcomes, minimal false alarms and ongoing full clinical trial suggest potential for widespread adoption, especially given healthcare staffing shortages and the push for more efficient patient monitoring solutions.

Published in the Journal of Clinical Anesthesia, results from the two-phase, 250 patient pilot study show clinicians found a majority (
82% ) of the alarms from the wireless and wearable Portrait Mobile monitoring solution to be informative or useful to optimize patient care in medical-surgical units.1 - Study findings suggest that continuous monitoring helps provide critical information to clinicians, enabling them to intervene effectively before a patient deteriorates.
- Undetected patient deterioration, particularly post-surgery, can lead to hazardous yet preventable consequences, with 30-day mortality after surgery representing the third leading cause of death globally.2
With published alarm rates from critical care and cardiac telemetry units that number in the hundreds per bed per day, healthcare systems may be concerned with alarm management in lower acuity settings.3,4 The results from this study highlight the potential of the wireless and wearable Portrait Mobile monitoring solution to provide meaningful alarms for clinicians and help encourage clinical intervention while minimizing alarm fatigue.1
The COSMOS (Continuous Ward Monitoring with the GE HealthCare Portrait Mobile Monitoring Solution) pilot study compares continuous monitoring with Portrait Mobile to routine intermittent vital signs assessment only. Key findings include:
- In the Portrait Mobile group, there was an average of less than three alarms per patient per day.
-
Clinicians found a majority (
82% ) of the Portrait Mobile alarms to be informative or useful. -
Portrait Mobile alarms informed clinical decisions, and the most common nursing intervention was the initiation of oxygen therapy or increase in the concentration of oxygen administered to a patient. Clinicians were prompted to supplement oxygen in about
60% more patients assigned to the Portrait Mobile group compared to patients with intermittent monitoring only (49 vs. 33, respectively). -
In the Portrait Mobile group, continuous monitoring and alerts led to clinical interventions that reduced vital sign abnormalities by approximately
25% .
“Vital signs are typically checked every 4-6 hours after surgery. Consequently, there can be a delay between onset of problems and when they are recognized by physicians and nurses,” shares Principal Investigator Daniel I. Sessler, MD, formerly with Cleveland Clinic and now Professor and Vice President for Clinical and Outcomes Research at UTHealth Houston.* “Results of our COSMOS study indicate that continuous vital sign monitoring provides useful information to clinicians without burdening nurses.”
The results from the COSMOS Phase 2 pilot were recently presented during the American Society of Anesthesiologists 2024 Annual Meeting in
Continuous vital sign monitoring can help alert healthcare providers to a patient’s decline as it is happening, enabling timely intervention before a patient deteriorates. A majority of respondents (
“As healthcare systems grapple with workforce shortages and complex patient management, it is essential that providers be supported by technology to work efficiently and effectively. 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,” said John Beard, MD, Chief Medical Officer of Patient Care Solutions, GE HealthCare.
“Continuous physiologic monitoring solutions can meet the challenge to alert care teams for changes in patient status but must be properly configured to optimize 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 that are engineered to adapt to rapidly changing patient needs. GE HealthCare’s technology has been recognized globally for its design, receiving the iF Design Gold Award for Product Design in 2022 for Portrait Mobile and an iF Design Award in 2023 for CARESCAPE Canvas.
