Empowering Modernization of Healthcare Applications for a Leading Global Healthcare Technology Solutions Provider in the US

The inflection pointChallenge

Our Customer is a global leader in health information technology, dedicated to advancing healthcare delivery and improving the health of communities worldwide. The organization serves over 27,000 facilities globally, including more than 2,650 hospitals, 3,750 physician practices, 40 employer sites, and 1,600 retail pharmacies. By delivering integrated clinical and financial platforms, Cerner empowers healthcare providers to streamline operations and manage revenue cycles efficiently through innovative technology. As a massive global entity, Cerner faced the complex task of evolving its legacy systems to meet modern healthcare standards.

  • Legacy systems transformation: A large portfolio of legacy Visual Basic applications required migration to a more scalable, efficient, and future-ready platform.
  • Interoperability challenges: There were significant gaps in seamless data exchange across clinical, financial, and enterprise systems, necessitating the adoption of advanced integration capabilities.
  • Application modernization needs: Critical applications, including inpatient pharmacy and registration modules within the Customer’s Millennium Suite, required a structured modernization approach to enhance functionality and performance.
  • Reliability and performance assurance: Mission-critical production applications needed strengthened operational oversight to ensure high availability, stability, and optimal performance.

Good to knowFrequently asked questions

What is healthcare application modernization?
Healthcare application modernization is the process of upgrading legacy clinical and administrative software — re-platforming, re-architecting or rebuilding it — to improve scalability, security, interoperability and maintainability while preserving critical functionality and data.
What are HL7 and FHIR, and why do they matter?
HL7 and FHIR are healthcare data-exchange standards. HL7 defines messaging for clinical and administrative data; FHIR is a modern, API-friendly standard using RESTful web services. Together they let different health systems share patient data securely and consistently.
Why migrate legacy Visual Basic applications to .NET?
Migrating from legacy Visual Basic to .NET improves performance, security and maintainability, unlocks modern frameworks and cloud services, and reduces the risk and cost of running unsupported technology while preserving critical business logic.
What is SMART on FHIR?
SMART on FHIR is an open standard that lets third-party applications securely plug into electronic health record systems using FHIR APIs and OAuth 2.0 authorization, enabling interoperable, app-based clinical tools that run across different EHR platforms.
How is interoperability achieved between clinical systems?
Interoperability relies on shared standards (HL7, FHIR, DICOM, X12), integration engines such as Mirth, Rhapsody or Cloverleaf, and secure APIs. These translate and route data between labs, pharmacy, radiology and enterprise systems so information flows consistently.
