Remote Patient Monitoring Solution

Bottlenecks in Data Stream

With an increasing number of clinics and patients onboarded, Alertive's system was strained by large amounts of critical vital measurements it had to store and process. They faced challenges in:

• Handling different methods of data input from LTE-supported devices, BLE-connected mobile apps, and entries by healthcare staff from their purpose built EMR.

• Analytics and data representation in an easily digestible form for the care team leveraging reduced clicks for faster and more accurate care of patients.

Inconsistent Note-Taking

Another significant concern was the scaling of clinical documentation between the clinical care team and patients, exacerbated by:

• Multiple versions of templates lead to inconsistent notes.

• Tedious and error-prone manual copy-pasting tasks.

• Unstructured and noisy output that made it difficult to find important information.

Data Stream Solutions

• Deployed DynamoDB to store vital readings.

• Employed AWS services like SNS and SQS for asynchronous operations.

• Calculations and analytics were pre-calculated and stored in RDS, making it easily accessible for the care team through the dashboard.

Note-Taking Solutions

The Note Wizard feature was developed to:

• Minimize free-text input and automate boilerplate text.

• Streamline the note-creation process to enhance completeness and accuracy.

• Serve multiple purposes like aiding clinicians, ensuring compliance, and tracking patient history.

Code Optimization

To deal with the performance challenges, a comprehensive code optimization effort was undertaken to revamp the Patient Profile page. This included rectifying React rendering issues and enhancing state management using Redux Toolkit.

Robust Backend Architecture

Leveraging a micro-services approach built on AWS, the architecture was designed to accommodate both asynchronous and synchronous operations efficiently. This robust foundation made use of AWS services like DynamoDB, RDS, SNS, and SQS and facilitated:

• Real-time data processing and analytics.

• Scalable and reliable inter-service communication using RPC mechanisms.

Note Wizard

To solve the note-taking challenges, the “Note Wizard” was introduced, a multi-step form aimed at:

• Standardizing note templates.

• Reducing errors and improving consistency.

• Serving as a guide and training aide for the care team.

Mobile App Support

Complementary iOS and Android apps were developed for patients, offering an integrated experience across devices.
