IRVINE, Calif.--()--Masimo (NASDAQ: MASI) today announced that University Hospitals (UH) of Cleveland is using Masimo Patient SafetyNet™, a remote monitoring and supplemental alarm system, to combat nurse burnout by improving workflows and reducing workloads. As the COVID-19 pandemic continues to strain healthcare infrastructure around the world, hospitals are dealing with higher than usual rates of nurse turnover. Patient SafetyNet offers a technological approach to supporting nursing workflows, as both UH’s experience and clinical evidence have shown.

During the pandemic, more than 80% of hospitals have reported an increase in nurse turnover.1 In a survey of more than 20,000 nurses conducted in 2020, 18% intended to resign, 50% responded that work was negatively impacting their health, and 47% reported that insufficient staffing contributed to their desire to leave the profession.2 Nurse staffing shortages have been associated with both increased costs and, crucially, decreased patient safety: A survey of 138 facilities covering more than 120,000 nurses found that the average cost of turnover ranged from $37,400 to $58,400 per nurse.3 And an observational, retrospective study of almost 200,000 patients across 43 hospital units found a significant association between increased patient mortality and nurse staffing below target levels.4

In a newly released testimonial, available here, UH – one of the largest health systems in Ohio – shows how their experience with continuous remote monitoring using Patient SafetyNet, is positively impacting their nursing practices and the quality of care nurses are able to provide while improving efficiency and staff satisfaction. Within three weeks of implementing Patient SafetyNet, for example, UH found that the average time between obtaining a patient’s vital signs at the point of care and documenting them in the electronic medical record (EMR) had decreased from more than 60 minutes to less than 5 minutes, resulting in a time savings of one FTE per shift.

UH first implemented Patient SafetyNet in 2016 following an incident in which an unnoticed, rapid deterioration in a patient’s condition resulted in emergency resuscitation and ICU transfer. Jenna Zarack, a nurse at UH’s Geauga Medical Center, said that Patient SafetyNet is “a great way to protect patients; it’s a great way to protect nurses, and for nurses to be able to help their patients in a fast, immediate response, so we don’t get to a code, we don’t get to a rapid response situation.” Sara Knowles, MSN, Clinical Nurse Specialist at UH, added, “The technology allows us to have eyes on our patients 24/7, which has proven especially valuable during our nursing shortage and the global pandemic.”

When asked why UH is now planning to expand use of Patient SafetyNet – which is already in use in 8 med-surg units across 5 UH hospitals – Michelle Hereford, UH’s Chief Nursing Executive, explained, “We’ve found that Patient SafetyNet’s continuous surveillance monitoring and automation capabilities help lower the burden on nurses and support them in providing quality care for every patient and catching potential patient deterioration before it’s too late. Coupled with the improvements we’ve seen in efficiency, staff confidence, and staff satisfaction since installing the system, expanding use of Patient SafetyNet is frankly a no-brainer.”

In addition to the experiences of Patient SafetyNet users like UH, there is significant clinical evidence for the efficiency and workflow benefits the centralized surveillance monitoring system offers, such as:

  • In a recent study published in the Journal of PeriAnesthesia Nursing researchers evaluated the utility and impact of Patient SafetyNet by surveying nurses before and after implementation and found that use of the system decreased the number of physical assessments, resulting in a reduction in nursing workload, and also recommended the use of continuous respiratory rate and oxygen saturation monitoring (which was implemented as part of the system) after general anesthesia, for patients’ safety.5
  • In a study conducted at Dartmouth-Hitchcock Medical Center, researchers investigated the impact of Patient SafetyNet on clinical workflow, and found a significant decrease in the time required to obtain and record vital signs (with mean assessment time dropping from 179 seconds to 129 seconds, saving an average of 3 hours a day in a 36-bed unit). They also found a significantly higher rate of patient data being accurately filled out in electronic medical records (EMRs), and an overall “very high” staff satisfaction rate with the system. The researchers concluded, “The enhanced monitoring system received high staff satisfaction ratings and significantly improved key clinical elements related to early recognition of changes in patient state, including reducing average vital signs data collection time by 28%, increasing patient monitoring time (rate ratio 1.22), and availability and accuracy of patient information.”6

Patient SafetyNet, powered by the Masimo Hospital Automation™ platform, displays real-time information from connected Masimo and third-party devices at central stations and on remote smart devices using Replica™, helping clinicians keep track of up to 200 patients per view station at a time. In addition, the system allows actionable alarms and alerts to be sent directly to clinicians, regardless of their location. Automatic escalation is provided for unattended alarms, helping to facilitate better awareness when patients need assistance. In addition to the workflow and workload reductions it offers, use of Patient SafetyNet for continuous remote supplemental monitoring with Masimo SET® pulse oximetry has been shown to have a significant impact on patient outcomes. For example, in multiple studies conducted over ten years at Dartmouth-Hitchcock, researchers found dramatic reductions in rapid response rescue events, ICU transfers, and zero deaths or preventable brain damage due to opioids in monitored patients.7-9

In addition to its powerful connectivity and automation features, which drive improvements for patients and nurses alike, Patient SafetyNet also offers powerful, integrated data aggregation and reporting software, Iris® Analytics. Designed to transform patient data into actionable information on hospital performance, floor protocol, and individual patient progress, Iris Analytics allows users to analyze past alarm events, notifications, and much more, to gain insight into their institution’s performance—and model improvements to support the reduction of nuisance alarms and thus improve workflows. Based on analysis of even just one to two weeks of past alarm event data, the Limit Analysis Report helps clinicians simulate alarm scenarios using theoretical alarm thresholds and delays, providing key data to help them evaluate and refine their alarm strategies to better meet their needs.

UH Chief Clinical Transformation Officer, Peter Pronovost, MD, commented, “Masimo Patient SafetyNet has been a valuable component in advancing our Zero Harm initiative within the University Hospitals system. It’s allowed us to increase the efficiency of our caregivers, reduce clinical errors, and help us focus on the timely delivery of compassionate care to our patients. It has also been a critical monitoring partner during the pandemic, when the condition of our COVID patients can dramatically change.”

Joe Kiani, Founder and CEO of Masimo, said, “As the pandemic continues, hospitals and other healthcare facilities are coming up against resource limitations across the board – from equipment, supplies, and beds to doctors and administrative staff – but the shortage of qualified nurses, due to burnout, may be the most significant challenge of all. Masimo has spent more than 25 years improving monitoring and automation technologies designed not only to improve patient outcomes and reduce the cost of care, but to make it easier for nurses to do their jobs effectively and efficiently. We hope that more and more institutions, like University Hospitals, will have the opportunity to experience the benefits that Patient SafetyNet can provide for patients and staff alike.”
