GE HealthCare (Nasdaq: GEHC) today announced the publication of data from a two-phase pilot study conducted with Cleveland Clinic in the peer-reviewed Journal of Clinical Anesthesia, highlighting performance of the wireless and wearable Portrait™ Mobile monitoring solution in the post-surgical ward environment.
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.[iii],[iv] 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.[i]
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 Philadelphia. The Phase 2 pilot enrolled 150 post-surgical patients who were randomized to routine vital signs assessment, or continuous monitoring of respiratory rate, oxygen saturation and pulse rate with Portrait Mobile. In the Portrait Mobile group, investigators alerted clinicians when vital sign values exceeded the designated thresholds based on continuous monitoring. In both groups, clinicians maintained routine care of vital signs measurement at 4-hour intervals. The study demonstrated that real-time alerts from Portrait Mobile reduces the duration and severity of vital sign abnormalities. Following the COSMOS pilot completion, a full clinical trial is currently underway (NCT06133140).
