Connectivity

Safe, Secure and Ready to Deploy

The Patient Status Engine is the only wireless patient monitoring system that includes the wireless connections as part of the regulated CE-marked and FDA-cleared end-to-end platform. 

By including the wireless connections (Bluetooth, Wi-Fi and cellular 3G/4G) as part of the overall system design, the PSE achieves unprecedented reliability in terms of eliminating data loss and ensuring data security, integrity and provenance. The PSE utilises system design principles and multi-layer redundancy to mitigate wireless connectivity failures due to interference or drop out. The PSE optimises data integrity over data immediacy, fitting the intended use as a patient surveillance and early warning system, that can predict and foresee adverse events before they occur. In this way the PSE promotes new pro-active care paradigms, rather than older reactive practices.

The Patient Gateway

The Patient Gateway is the data entry and local display point in the Patient Status Engine where patients, users and devices are validated and connected to the network, early warning thresholds are set and automatically generated real-time patient charts are displayed.

The Patient Gateway comprises an Android tablet running Isansys applications (certified as part of the overall PSE regulatory approvals) that receives the incoming data via doubly encrypted Bluetooth from the wearable sensors on the patient. It locally processes the incoming sensor data and displays the patient’s health status in real-time in an easy to read format. The Gateway is also connected via secure WiFi (or 3G/4G) to the Lifeguard Server, to which it transmits both raw and processed data. Clinicians and nurses can act on the local information displayed on the Gateway, even in the event of Wi-Fi or cellular network interruption. No data is released from the Gateway until it is received and fully acknowledged by the Lifeguard Server.

Lifeguard Server

The Lifeguard Server is the back-end IT system that combines several functions to provide a scalable, secure and robust end-to-end patient data capture and analysis platform. It features an open API to provide straightforward connectivity via HL7 / FIHR plug-ins with electronic medical records and other hospital information systems.

Its main functions are:
(a) aggregating the patient data from multiple Patient Gateways in a hospital or community setting, and presenting all the data on the open API 
(b) providing network control functionality to ensure accurate timing and stability in all the wireless sensors and Gateways operating in the system
(c) providing dashboards, electronic patient charts and user interfaces via a secure web-services portal

 

The Central Monitoring Unit (CMU)

The CMU serves as a live control centre, where staff can remotely monitor patients 24/7, with real-time patient data and early warning indicators presented on computer screens. Monitoring staff can then make calls to alert ward staff when patients are becoming unstable or need attention.

The CMU may be centralised with all the patient data being aggregated in one place, or localised with the monitoring stations being located at the nursing station in each ward or section of the hospital. In addition, to enhance the care and safety of all their patients, clinicians and nurses may also access their patient’s health status on authorised mobile devices.

Integration

The Patient Status Engine has been designed for straightforward integration withother IT platforms. The open API and HL7 / FIHR plug-ins ensure technical interoperability with exisiting and future EMR and clinical HIS systems. 

The systems design methodology and on-going input from clinical teams, particularly nurses, in the development of the PSE ensure straightforward integration into existing nurse workflows. The configurable platform design means that the PSE can be evolved to integrate with future work flows and new patient care pathways. 

Depending on local IT and data governance procedures and requirements, the Lifeguard Server can be installed as a virtual machine in the healthcare providers own IT infrastructure, or it can run in a secure cloud. In either case, integration with other IT systems is straightforward.

Networks

The Patient Status Engine is a complete end-to-end, all wireless multiple vital sign system that integrates Bluetooth, Wi-Fi and cellular 3G / 4G networks within the platform itself. 

By including the wireless connections as part of the overall system design, and within the scope of the regulatory certification and clearances (Class IIa CE-marked and Class II 510(k) cleared medical device) the PSE achieves unprecedented reliability in terms of eliminating data loss and ensuring data security, integrity and provenance.
