By delivering integrated clinical and financial platforms, Cerner empowers healthcare providers streamline operations and manage revenue cycles efficiently through innovative technology. Customer Challenges As a massive global entity, Cerner faced the complex task of evolving its legacy systems to meet modern healthcare standards. Key challenges included: 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. Solution Delivered by Adroitent Adroitent played a pivotal role in the architecture, design, and integration of core solutions within the Cerner ecosystem. Key contributions included: Design, and development: Led architecture, design, development, quality certification, integration, and support for multiple core solutions within the Customer’s Healthcare ecosystem. Modernization approach: Defined target architectures for mission-critical uplift programs and successfully migrated legacy Visual Basic applications to the .NET platform that improved the scalability, performance, and maintainability. Teams also played a key role in defining the target architecture for multiple mission-critical uplift programs such as Inpatient Pharmacy and Registration from their Healthcare Millennium Suite. Interoperability & API development: Designed and implemented healthcare integrations using HL7 and FHIR standards. This included building FHIR-based RESTful APIs to support both modern and legacy hybrid integration scenarios. Quality engineering: Developed custom quality certification and testing tools to strengthen automated quality control. Ensured system stabilization by conducting rigorous performance and memory testing and resolved root-cause issues through crash analysis to ensure system stability. Crash analysis and performance tuning: Stabilized mission-critical applications through in-depth crash analysis, performance tuning, and root-cause resolution to ensure production reliability. Agile methodology: Adopted Agile practices, delivering features through structured sprint cycles to ensure timely implementation, continuous feedback, and iterative improvement. Adroitent maintained a long-standing, high-capacity partnership with the customer to ensure the continued stability and seamless operation of their mission-critical systems. Duration of involvement: 10+ Years Team size: 45+ specialized professionals Methodology: Agile Tools & Technology Leveraged Adroitent leveraged a comprehensive suite of healthcare and enterprise technologies to deliver the engagement effectively. Standards: Secure network protocols, HL7/DICOM standards, FHIR R4, CDA, and X12 (EDI) Frameworks: SMART on FHIR, .NET Platform. Middleware/Engines: Open Engine, Mirth, Rhapsody, and Cloverleaf. Security: OAuth 2.0, TLS/SSL, and Token-based exchange. Business Outcomes Enhanced scalability: Successful migration to .NET improved the performance and maintainability of the customer’s critical healthcare applications. Seamless interoperability: Enabled unified data flow across labs, radiology, pharmacy, and external devices via standardized FHIR and HL7 interfaces. Improved quality & reliability: Automated quality control and root-cause resolution led to stabilized production environments for mission-critical apps. Clinician-centric results: Modernized UIs (PowerChart) and streamlined clinical workflows allowed physicians to focus on patient care rather than the underlying technology.
