Hospital Asset Tracking solution: enabling hospital's to track and monitor critical ventilator assets remotely.

Hospital Asset Tracking solution to deliver real-time ventilator monitoring.

The solution.

We designed our Hospital Asset Tracking solution, built on our world-leading Rayven Platform to help our client obtain real-time visibility of ventilator location and utilisation.

Defining what data to collect is critical.
We began by identifying the data needed to deliver the necessary the goals. For this, it would include:

1. Ventilators’ status and location
2. Bed locations and status
3. Schedule information

Initial goals of the solution.
The first step was to connect the ventilators, collect data in a consistent and reliable manner, and then ensure the data’s ongoing quality and integrity. This would enable us to to provide the following features in our Hospital Asset solution:

1. Monitoring of critical operational data received from the equipment via a web-based system
2. Device management monitoring
3. The ability to define the logic for the application in order to meet the desired objectives
4. Provide alarm and alert notifications via email or SMS messages
5. Start collecting historical data to enable utilisation forecasting
6. Provide the right dashboards to the right users with the right insights
7. The ability to properly test the application, making sure all of the above goals are met, based on the below solution architecture.

Before go-live, we tested four critical aspects of the Hospital Asset Tracking solution:

Security.
The Rayven Platform is built with security as a top priority and our proprietary security architecture ensures that data is secure at all points of the environment.

The solution includes data encryption in transit from device-to-cloud, as well as device authentication; security (Bearer) tokens; SSL, AES and RSA encryption; as well as additional device security checks done via automated polling.

Connectivity.
Once securely connected, the ventilators send their usage data via a 4G gateway to the Rayven Platform. With bed and ventilator location data, this is collected through Bluetooth beacons, which then forward that data onto the 4G gateway and into the system.

Data integrity.
It is critical to ensure that the data collected is reliable. Initially the beds and ventilators were moved around the hospital to confirm that their location and telemetry was the same as that presented on the Hospital Asset Tracking solution dashboard. Once this was tested and confirmed, we started working on building the business logic.

Industrial data science.
The objective of the exploratory data analysis was to identify trends in the data, which included:

1. Usage patterns compared with forecast usage
2. Maintenance and failure alerts

What’s next?

We are gathering data that will help us to improve usage forecasting and predictive maintenances schedules for the ventilators, which will provide insights into how their performance can be optimised and asset uptime increased.
