Powering a Chronic Care Management Solution with Seamless EHR, IoMT, and Lab Integrations

-
Partner
A U.S.-based company in the chronic care space offers a SaaS platform backed by clinical validation. It connects patients with medical teams and enables coordination with care providers. The system is built for providing regular treatment of complex diseases such as heart failure and diabetes. It can adapt to a patient's changing needs throughout their life.
Given that it is a healthcare company working under tight regulations, they wanted to guarantee that information is sent securely and quickly to others. Its platform remains reliable even when deployed in environments that differ significantly in infrastructure or clinical workflow.

Business Challenge
The partner struggled with deep interoperability issues that disrupted care coordination. Data remained scattered between EHR platforms and external diagnostic systems, making it difficult for care teams to access timely insights. The engineering team was buried with constant integration requests, offering few opportunities to work on the core product.
New customer onboarding involved manual configuration and interface customisation, which caused delays and technical debt to accumulate. The increasing overhead of keeping these custom connections was a strain on the team. Rebuilding the platform from the ground up was out of the question, so an API-first approach was embraced: one that enabled modernization without jeopardizing the stability users relied on.

Solution
Jelvix joined the client as the long-term integration partner to build a scalable, API-first integration architecture. This model abstracted the data from disparate EHRs, labs, and IoMT devices into a standard format and normalized content, facilitating consistent data exchange with the CCM platform. Adapters that can be reused and real-time ingestion pipelines ensured smooth communication without interfering with backend processes. The modular system also facilitated rapid onboarding of new clients and systems, keeping the focus on product innovation.

Product Overview
Client’s goals
The client aimed to eliminate data silos that disrupted care workflows and made it difficult to deliver timely insights. They wanted to streamline the process of onboarding new healthcare providers, improve customer satisfaction, and ensure compliance with regulations across several countries. One key priority: allowing the in-house team to get back to patient-facing product features by taking integration maintenance off their plate.

Implementation
The engagement kickstarted with a discovery phase where we centred our analysis around the prevailing integration landscape. Jelvix team members collaborated with client engineers and stakeholders to audit the current data sources, pinpoint the bottlenecks, and document compliance demands HL7, FHIR, and HIPAA. The team spoke to stakeholders and observed data flow in real life to determine where integration delays were bottlenecking clinic operations and product scale.
It resulted in work on a modular, API-first architecture with support for structured and semi-structured inputs, which included adaptive adapters, protocol transformers that could be reused, etc. The platform was built to onboard new sources of data without needing to re-architect or take the platform offline.
During product development, Jelvix ensured backward compatibility and simplified future expansion by isolating responsibilities through clean API boundaries.
The integration layer was tested with several clinics prior to widespread release, including high-volume providers. These pilots provided the team with the opportunity to iterate on data mapping logic and to verify transformation pipelines. Now stabilized, the solution launched incrementally with a targeted onboarding, comprehensive documentation, and ongoing support. New endpoints were added through templated workflows as the client’s partner network grew, reducing overhead and ensuring consistency.
Value Delivered
The delivered architecture resolved core pain points without rewriting the legacy platform. Unified data ingestion improved accuracy and visibility across the care team network. By making integration independent of backend logic, the client now has an adaptable, future-ready interface layer capable of growing with advancing clinical and regulatory requirements.
Integration times were halved, allowing quicker go-lives and increasing the client’s reach in the market. Resources were moved from engineering to driving strategic product development. It also decreased the friction associated with onboarding and working across different systems for care teams. Clean, standards-based pipes now enable consistent performance and protocol adherence across the entire chronic care ecosystem.

Project Results
User feedback collected after implementation indicated a 35% gain in satisfaction for care teams related to data continuity. Integration cycles shrunk to less than half the original, with much quicker clinic or provider group onboarding. The cost of internal engineering hours of support and maintenance decreased 42%, freeing up the product team to work on innovation.
The platform currently offers full interoperability with 7 EHRs, 4 lab providers, and more than a dozen types of IoMT devices. It was able to grow into three new geographical markets in a highly effective manner and localized user interface variations in the process. The modular integration layer enables future growth of the company and provides the possibility to release features iteratively, without disrupting the core systems.
