Bi-Directional HL7
Interface Implementation for CareHere LLC (Now Premise Health)
Streamlining Lab Orders and Results Through Seamless HL7 Integration with a Legacy EHR System

Client Overview
Client: CareHere LLC (acquired by Premise Health)
Industry: Employer-sponsored healthcare and wellness
Location: Nashville, Tennessee
Scope: 165+ clinical sites across the U.S.
Solution Overview
ChampSoft designed and implemented a comprehensive, bi-directional HL7 interface leveraging Mirth Connect to automate communication between CareHere’s EHR and two major third-party systems: LabCorp (laboratory provider) and Change Healthcare (formerly Emdeon, used for electronic order entry).
Business Challenge
CareHere, a rapidly growing provider of on-site and near-site health centers, was grappling with a heavily manual and error-prone laboratory order and results process within its proprietary Classic ASP-based Electronic Health Record (EHR) system. The existing infrastructure was not equipped to manage electronic lab interfacing, requiring significant staff intervention and introducing potential for human error, delays, and inefficiencies.
Results & Impact
- Deployment Time: 6 months (delivered under budget)
- Scalability: Successfully rolled out to all 165+ CareHere clinics
- Transaction Volume: System now handles over 4 million HL7 transactions annually
- Operational Efficiency:
- Eliminated manual lab requisition forms
- Streamlined order creation and results ingestion
- Minimized errors and delays in patient care
Key Features & Capabilities
Retrofitting the Legacy System
Modified the legacy EHR database schema and architecture to support structured HL7 data from LabCorp, overcoming compatibility issues.
Advanced Data Matching
Developed a hierarchical algorithm to reconcile mismatches in patient demographics between systems, eliminating the need for manual reconciliation.
Full Automation
Enabled real-time, automated transmission of patient demographic data, provider details, and lab orders to Change Healthcare, and receipt of lab results from LabCorp directly into the EHR.
Error Mitigation
Achieved a post-implementation error rate of less than 1%, a drastic improvement from the previously manual process.
Why It Matters
ChampSoft’s robust solution helped CareHere modernize its lab interfacing process without the need to overhaul its entire EHR system. By bridging the gap between outdated infrastructure and modern interoperability standards, ChampSoft delivered immediate, scalable improvements in patient safety, clinician efficiency, and data accuracy.
