In an effort to provide pharmacists and clinicians with a secure way to quickly access an accurate test history for their patients, the company set its sights on creating a convenient web-based portal with the power to integrate automatic data routing to the pharmacists’ individual EMR systems.
But there was a serious issue: creating this powerful solution would require taking advantage of cloud computing — an area in which the medtech company had little experience. To accelerate development and fill in gaps in their technical knowledge, they turned to ICS for assistance.
Tapping extensive cloud expertise, ICS architected an AWS-native portal for routing results from testing instruments to external laboratory information systems (HL7v4/FHIR) leveraging AWS IoT Core, S3, EC2, RDS and Lambdas. Because the solution needed to handle millions of test results, ICS utilized load balancers across multiple regions for low-latency website access.
In addition, the engineering team used Lambda functions for custom LIS integration and AWS RDS to provide a managed database using the MySQL driver, which allows the database to scale with usage. ICS found that using AWS IoT Core as the managed MQTT broker allowed the development team to securely manage the fleet of mobile devices with ease.
To ensure the solution was protected from cyber threats, we integrated our development environment into a secure and scalable production-capable platform that could protect the data in transit and at rest via an encrypted database and SSL certificates.
The system is simple to use. First, patients install an app on their personal Android or iOS device to allow them to take a picture of their test result. A computer vision algorithm then analyzes the cartridge reading to determine whether the patient is positive for a specific virus.
This test information is then securely transferred through a managed MQTT broker built on top of AWS IoT Core technologies. An encrypted, scalable database built with AWS RDS stores the data for later viewing via an intuitive web app or for forwarding to a configured customer LIS or EMR. By accessing the convenient web portal, pharmacists can view the results of an individual patient’s test and accurately fill the relevant prescription.
