GE HealthCare released new data from a pilot study with the Cleveland Clinic evaluating the Portrait Mobile wireless and wearable monitoring solution, showing that continuous patient monitoring using it resulted in alarm data suitable for optimization of ward default values and further refinement on an individual basis seems likely to improve usability.
The COSMOS (Continuous Ward Monitoring with the GE HealthCare Portrait Mobile Monitoring Solution) Phase 1 study enrolled 100 post-surgical patients who had respiratory rate, oxygen saturation, and pulse rate monitored continuously with Portrait Mobile. The results show continuous monitoring of these vital signs with Portrait Mobile produces data to drive alarm threshold configuration in the ward, optimize actionable alarms, minimize non-actionable alarms, and minimize alarm fatigue.
“Most patients recovering from surgery have vital signs evaluated every 4-6 hours. We know that intermittent monitoring misses many vital sign abnormalities,” principal investigator Daniel Sessler, MD, Michael Cudahy Professor and Chair of Outcomes Research at Cleveland Clinic, told the press. “Our analysis identified alert thresholds that identify potentially serious abnormalities without generating undue burden for nurses.”
The COSMOS study used alarm burden analytic software to evaluate the interaction of physiologic data, duration of alarm delays and alarm thresholds to determine the potential number of alarms on Portrait Mobile per patient per day at various configurations. The initial average of alarms per patient per day was seven, but after adjusting thresholds for those patients with >24 alarms per day, the average dropped to three per day, or roughly one alarm every eight hours, per patient.
“In an era where clinician workforce shortages are causing burnout, we are focused on easing the way for care teams to deliver more confident patient care,” said John Beard, MD, chief medical officer of Patient Care Solutions, GE HealthCare. “To reduce preventable patient harm from delayed recognition of clinical deterioration, and help alleviate alarm burden on care teams, continuous monitoring requires a technically robust system and properly configured physiologic thresholds to develop caregiver trust and support timely intervention. The COSMOS Phase 1 data presented at ASA represents an essential step in Portrait Mobile system configuration to meet the potential of continuous physiologic monitoring in the ward environment.”
