Overview

Visensia, developed by OBS Medical, is an advanced physiological monitoring software that leverages artificial intelligence to analyze continuous or episodic vital sign data. It fuses up to five vital signs—heart rate, respiration rate, temperature, oxygen saturation, and blood pressure—into a single, intuitive metric called the Visensia Safety Index (VSI). This index provides healthcare professionals with an early warning of patient deterioration, often hours before traditional methods, thereby enhancing patient safety and enabling timely clinical intervention. Designed as an accessory to standard multi-parameter patient monitors or clinical information systems, Visensia integrates seamlessly with existing hospital infrastructure via a standard Health Level 7 (HL7) interface. The system offers various display options, including a ‘Bingo Board’ for an overview of multiple patients and a ‘Drill Down’ for detailed patient information, along with automated audible and visual alerts when the VSI exceeds defined thresholds. Visensia is utilized across various care settings, including hospitals (general wards, critical care), emergency medical services (EMS), and remote patient monitoring in community and home environments.

What Physicians Need to Know

Evidence Base

Visensia's core functionality is based on comparing a patient's vital signs against a model of normality derived from a population of high-risk patients. This model was developed from 3,500 hours of continuous vital sign monitoring data collected at the John Radcliffe Hospital (Oxford, UK) from 2004 to 2006. The system uses a non-linear combination of up to five vital signs: heart rate, respiratory rate, temperature, blood pressure, and arterial oxygen saturation. The Visensia Safety Index (VSI) is an artificial intelligence (AI)-based Early Warning Score System (EWSS).

Clinical Validation Studies

Visensia has undergone clinical validation studies in both the UK and the USA. Proof-of-concept work at the John Radcliffe Hospital found that in 168 monitored patients, 95% of severe physiological abnormalities identified by the system were deemed valid alerts by senior clinicians. A 3-phase study at the University of Pittsburgh Medical Centre (UPMC) involving 630 patients demonstrated that Visensia could accurately predict patient deterioration and Medical Emergency Team (MET) events, with a mean advanced detection time of 6.33 hours. In Phase 3 of the UPMC study, the use of the Visensia index to alert nursing staff led to a 58% reduction in critical instability events. Data from St. Joseph Mercy (Oakland, US) over four years showed a 37.5% decline in code-blue responses, a 34.5% reduction in mortality rates, and nearly a half-day reduction in patient length of stay, despite a 22% increase in patient illness severity. One study found that patients monitored with Visensia had a statistically significantly shorter average duration of cardio-respiratory instability and fewer episodes of serious and persistent instability.

Alert Fatigue Management

Visensia aims to address alarm fatigue by providing a single, unambiguous call to action. The system's alerts are designed to be validated and appropriate, especially when compared to single-channel alarms, contributing to high sensitivity and specificity. The Visensia Safety Index (VSI) fuses multiple vital sign data into one numerical index, reducing the number of individual alarms. The VSI provides a graduated score based on patient datasets, rather than arbitrary alarm cutoff levels, which can help in reducing irrelevant alerts. The alert threshold for the VSI is clinically validated and cannot be changed by users, which helps maintain the relevance of alerts.

Override Rate Data

While general clinical decision support systems can have high alert override rates (ranging from 46.2% to 96.2%), with varying appropriateness depending on the alert type, Visensia's design focuses on providing a highly reliable and validated alert to minimize inappropriate overrides. The system's alerts are intended to be a clear call to action, which can help in reducing the tendency to override.

Guideline Update Frequency

Visensia's model of normality for vital signs is derived from a database of high-risk patient groups. The system calculates the Visensia Index whenever new data is received, ensuring real-time analysis. While the core model is established, the system continuously processes and updates the patient's VSI based on incoming physiological data. The VSI is recalculated and the alert status updates every time new vital sign data is received.

Clinical Workflow Integration

Visensia is designed as an accessory to standard patient monitors or medical information systems. It uses a standard Health Level 7 (HL7) interface for communicating with other data acquisition systems, such as bedside monitors, central stations, telemetry kits, and electronic patient records (EMR), allowing healthcare organizations to use existing monitoring infrastructure. The Visensia Index has been integrated into clinical workflows through partnerships, such as with Excel Medical's clinical decision support platform. The system aims to prioritize clinical workflow and resource utilization. Visensia Mobile extends the benefits to rapid response and critical care outreach teams who are not always in a specific unit.

Decision Audit Trail

The Visensia system displays a history of the patient's VSI and the values for each vital sign, along with the time they were last recorded, in graph form. This trending data provides a record of the patient's condition over time. The system also indicates when a Visensia alert has activated, highlighting the patient's condition for an appropriate response.

Physician Tip

Visensia provides an early warning of patient deterioration by fusing five vital signs into a single index, the Visensia Safety Index (VSI). This can help identify at-risk patients hours before traditional methods. The VSI can be used to objectively assess whether a patient is stabilizing or improving, aiding in step-down decisions or preventing unplanned readmissions. The system is an adjunct to, not a replacement for, vital sign monitoring and primary alerting systems. It helps prioritize nursing staff to the most acute patients and improves communication among care teams by providing a single, reliable data point for a patient's condition.

Visensia integrates with existing multi-parameter patient monitors, medical information systems, and Electronic Medical Records (EMR) or Clinical Information Systems (CIS) via a standard Health Level 7 (HL7) interface. It is compatible with various programming environments including .NET Framework, .NET (Core), Java, and Python, through its Software Development Kit (SDK). This allows for integration into existing medical devices or middleware software. Visensia has also been integrated with platforms like Excel Medical's clinical decision support platform and can utilize middleware such as Cerner's iBus.
