GE Healthcare has unveiled a wireless patient monitoring system that enables continuous monitoring during a patient’s hospital stay called Portrait Mobile,3 which helps clinicians detect patient deterioration.
Early detection of patient deterioration may help reduce length of stay and intensive care unit (ICU) admissions and improve patient outcomes.4 Portrait Mobile includes patient-worn wireless sensors which communicate with a mobile monitor.
Globally, an estimated 65% of hospital patients and over 90% of post-acute care patients are monitored manually and not continually.5 Many vital sign changes are missed during spot checks which often occur in four-to-six-hour intervals.6 A U.K. national audit of adult in-hospital cardiac arrests showed that more than half (57%) occurred on the wards and only 5% in the ICU7 where patients are monitored continuously. Most patients who end up in cardiac arrest or critical care, don’t suddenly deteriorate but rather present with earlier vital signs that show abnormal trends.8 Respiratory rate is the highest ranked variable in models predicting clinical deterioration in the hospital.9
With Portrait Mobile, respiration rate, oxygen saturation, and pulse rate for general ward and post-surgery patients can be captured wirelessly, continuously. This innovation allows caregivers to identify changes that may signal that cardiorespiratory complications or infectious disease may be developing. It gives clinicians the opportunity to act early and potentially avert serious adverse events.
“In an evaluation clinical study conducted at a London hospital in the UK, 90% of nurses reported that they feel more reassured about their patient’s condition when continuous monitoring is used versus vital signs spot check measuring,” says Erno Muuranto, Engineering Director at GE Healthcare in Finland. “Portrait Mobile provides reliable measurement technology and meaningful alarms in a mobile setting.”
For patients, Portrait Mobile’s wireless continuous monitoring helps with the ability to move about the hospital, without being restricted to the bedside. This also allows visitors to interact with the patient without technology getting in the way. Patient mobility may help improve patient outcomes and reduce length of stay, which may lower costs and elevate patient satisfaction10.
Portrait Mobile is designed to be as reliable as wired technology. Its routable communications architecture enables hospitals to leverage their existing network infrastructure when deploying the system, reducing installation, and maintenance costs.
Portrait Mobile was developed in Helsinki, GE Healthcare’s global center of excellence for monitoring solutions where engineers have been developing patient monitoring technology for decades. Today, GE monitors are used in hospitals across the world – from Beijing to London, New York, and more.
