The client is a US hospital seeking to improve treatment outcomes and identify potential health deterioration in patients with congenital heart disease.

The hospital envisioned an accessible remote monitoring solution that would collect vital signs using built-in smartphone sensors and securely exchange patient data with its EHR and EMR systems.

Business Challenge

  • The application needed to meet relevant medical data security requirements, including the HIPAA Rule.

  • Its machine learning component had to analyze patient data consistently enough to support clinicians’ assessments.

  • The solution required secure data exchange between the remote care application and hospital EHR and EMR systems.

  • The client wanted a simple experience delivered through an affordable, widely available device rather than specialized medical equipment.

Our Solution

Approach

It was crucial to replace medical devices like oximeters and sphygmomanometers with more widely used appliances. Our team has created a solution prototype – an app that runs on mobile phones. The measurement is based on the concept of Photoplethysmography (PPG) which uses the smartphone camera and optionally a LED flash in order to analyze the vital signs. Thus, a patient can measure heart rate, saturation rate, respiratory rate, and blood pressure using a mobile phone.

Implementation

Binariks tech team has landed on the idea of applying the ML CHF Processing. This technology allows us to predict the CHF status and communicate it with the hospital EMR system.

The prototype we’ve created can be used by hospitals through its own Authentication Policy (SMART on FHIR) that communicates with federal authentication. This part of the solution ensures that the app follows the HIPAA Rule and best practices of health data interoperability.

We have divided the solution into the app vendor side and the hospital side. This helped the client manage access to health data and, hence, secure it. In effect, each type of user so doctors and patients have easy access to the data they need.

Technologies used

  • Java
  • React
  • KeyCloak
  • AidBox
  • ML.NET

Value Delivered

Binariks delivered a prototype that made remote monitoring accessible through a smartphone while establishing secure interoperability between the patient-facing application and hospital systems.

  • 4 vital signs: The prototype enables smartphone-based measurement of heart rate, oxygen saturation, respiratory rate, and blood pressure.
  • HIPAA-compliant interoperability: The architecture supports secure data exchange between the remote monitoring application and hospital EHR and EMR systems.
  • Smartphone-based access: Patients with limited access to medical services can monitor their condition without relying exclusively on specialized devices or in-person visits.

Additional outcomes:

  • Simplified long-term monitoring for patients with chronic conditions
  • Separated hospital-side and vendor-side access to health data
  • Provided doctors and patients with role-appropriate access
  • Reduced the need for direct contact between patients and medical staff during epidemics
