Helping Improve Safety and Clinical Efficiencies on the General Ward
The general ward is challenged by low nurse-to-patient ratios, increasing case complexity and variability. Clinicians have long understood the value of monitoring in helping to alleviate these burdens, but previous solutions for this environment have been intermittent, delayed and/or limited in their effectiveness. Masimo has developed integrated monitoring technologies providing noninvasive and continuous measurements that automate and streamline the flow of patient data to improve clinical efficiency.
The ability to continuously monitor active patients in the general ward reliably – and to save clinicians’ time by documenting important physiological measurements in electronic medical records – allows clinicians to spend more time caring for patients.
Masimo offers an integrated portfolio of solutions designed to help clinicians focus on patients and improve workflows, including industry-leading SET® pulse oximetry, advanced measurement capabilities, vital signs monitors, portable monitoring devices, and a robust remote monitoring and clinician notification system.
Clinicians rely on patient monitors to alert them to adverse changes in a patient’s condition. Alarm fatigue – the sensory overload of an excessive number of alarms – can, however, result in desensitisation to alarms and missed alarms, as well as patient discomfort.
Masimo’s breakthrough Signal Extraction Technology® (SET®) overcomes the limitations of conventional pulse oximetry with the ability to measure through motion and low perfusion.
Two separate studies found that Masimo SET® pulse oximeters detected approximately 10 times more true events than other "Next Generation" pulse oximeters studied.1,2
Masimo SET® had 3% missed true alarms and 5% false alarms versus 43% and 28%, respectively, using competitor technology.3
Results shown are calculated by combining sensitivity and specificity outcomes of machine-generated and volunteer-generated motion.
In another study which compared the ability of three pulse oximetry technologies to detect hypoxic events, Masimo SET® pulse oximetry demonstrated the highest sensitivity and specificity during induced conditions of motion and low perfusion.3
In an 11-month study conducted at Dartmouth-Hitchcock Medical Center, Dr. Andreas Taenzer and colleagues found that using Masimo Patient SafetyNet and Masimo SET® pulse oximetry as part of a comprehensive alarm management strategy reduced rescue events by 65% and intensive care unit transfers by 48%, and as a result, reduced costs by $1,480,000.4,5 In a subsequent article, they announced that after five years, Dartmouth-Hitchcock had had zero preventable deaths or instances of brain damage due to opioids since the installation of Patient SafetyNet.5 In 2016, after ten years, they reported achieving a 50% reduction in unplanned ICU transfers and a 60% reduction in rescue events, despite increases in patient acuity and occupancy.6
Researchers found improved outcomes following installation of continuous post operative monitoring.4-6
Masimo technology includes a host of noninvasive measurements offered through many patient monitoring solutions, enabling care areas such as General Ward, which cater to a variety of patient cases and populations, to customize the type and degree of monitoring needed.
The Anaesthesia Patient Safety Foundation (APSF)9 and The Joint Commission recommend continuous oxygenation and/or ventilation monitoring for patients receiving opioid-based pain medications.10 However, current methods of respiration rate monitoring may be limited by shortcomings related to accuracy and patient tolerance.11,12 rainbow Acoustic Monitoring provides a noninvasive, continuous, easy-to-use, and reliable monitoring solution that has the benefit of higher patient tolerance.13,14
Masimo offers a portfolio of expandable and configurable patient monitoring solutions designed to adapt to changing patient needs.
Root with noninvasive blood pressure and temperature and Root with NomoLine capnography. The flexibility and expandability of the Root platform make it an ideal bedside solution, tailorable for both high- and low-acuity settings.
Root® is a powerful, expandable patient monitoring and connectivity hub that integrates an array of technologies to provide multimodal monitoring and connectivity solutions – in a single, clinician-centric platform that allows clinicians to tailor monitoring solutions for high- and low-acuity settings. Root’s plug-and-play expansion capabilities, as well as its availability in a configuration with integrated noninvasive blood pressure and temperature, allow clinicians to centralize patient monitoring by bringing together advanced rainbow SET™ Pulse CO-Oximetry, vital signs measurements, brain function monitoring, regional oximetry, and capnography measurements on an easy-to-interpret, customisable display, empowering clinicians with more information. Further, Root serves as a central connectivity hub, with automated electronic charting of Masimo and third-party device data and alarms to electronic medical record (EMR) systems, which may improve clinician workflows through the reduction of manual data documentation.
Root has the unique ability to bring together data and alarms from multiple third-party monitors — such as IV pumps, ventilators, and other multi-parameter monitors — automating the flow of patient data to the EMR, which may help streamline workflows, improve productivity, and reduce the likelihood of transcription errors.15
Used in conjunction with Patient SafetyNet or Iris Gateway™, Clinicians receive ADT information directly on Root, facilitating positive patient identification. Clinicians simply select a patient from a drop-down list or scan the patient’s wristband using an optional barcode scanner, attached to Root, to associate the patient, device, and clinician at the bedside.
The Radius-7® Pulse CO-Oximeter® is a Bluetooth®-enabled wearable monitor used in conjunction with the Root patient monitoring and connectivity platform. Radius-7 provides continuous tetherless monitoring so that patients can ambulate throughout the hospital and have freedom of movement while being continuously monitored. Two "hot-swappable," rechargeable modules with up to 12-hour battery life minimise monitoring interruption and require just one module exchange per shift. The use of single-patient-use armbands minimises the risk of patient cross contamination.
Masimo offers a variety of spot-check and vital signs measurement solutions, allowing facilities to select the best options for their patient needs and workflows.
Root and Root with noninvasive blood pressure and temperature can be mounted on a mobile roll stand, simplifying workflows by facilitating quick vital signs spot-checking and automatically documenting measurements in electronic medical records during rounds.15 Noninvasive blood pressure technology provides three oscillometric blood pressure measurement modes: spot-check, automatic interval, and stat interval. Accessories include both disposable and reusable cuffs for adult, paediatric, and neonatal patients.
Root also includes a number of additional features, such as the ability to connect to and serve as a hub for third-party devices and the ability to calculate an Early Warning Score (EWS) on demand, allowing clinicians to tailor monitoring to best suit a variety of clinical needs.
Masimo Patient SafetyNet optimises patient safety and clinician workflows through centralised, supplemental remote monitoring and automated charting. Near real-time information from any connected Masimo device, as well as supported third-party devices such as ventilators, is displayed at a central view station, allowing clinicians to quickly assess the status of up to 200 patients, review trend data, and investigate alarms.
When changes occur in measured values, which may indicate deterioration in a patient's condition, Patient SafetyNet automatically sends wireless alerts directly to clinicians, wherever they may be. In addition, Patient SafetyNet can automate the transfer of patient data, vital signs, early warning scores (EWS), and other physiological parameters directly to hospital electronic medical record (EMR) systems, helping to improve clinician workflows and reduce the possibility of transcription errors.15
Escalation Management — Actionable patient alarm notifications are sent to designated clinicians, with automatic escalation, facilitating immediate patient intervention.
Configure alarm thresholds and delays by patient population to manage alarms
Clinician is notified remotely of alarm at the bedside
If primary clinican does not respond, the alert is escalated to additional clinicans
Masimo’s unique approach to device connectivity leverages existing hardware and infrastructure to reduce the cost of connectivity. Iris Gateway and Patient SafetyNet connect Masimo and third-party medical devices’ data and alarms to provide streamlined and cost-effective meaningful use of EMR systems.
