Healthcare Lab Results Processing Automation

A regional healthcare facility processes hundreds of lab results daily from an external laboratory partner. With blood draws, urinalysis, and other tests conducted for 400-700 patients each day, the facility faced a critical bottleneck: lab results arrived via fax and required manual transcription into their electronic health record system. Lab results processing automation became essential when this manual process created dangerous delays in patient care, introduced transcription errors, and made compliance auditing nearly impossible.

The facility’s external lab partner processed blood, urine, and stool samples and returned results via fax – a standard practice in healthcare but one that created massive inefficiency downstream.

Daily volumes told the story of the scale:

• 300-525 blood test results per day
• 85-190 urinalysis results per day
• 6-20 stool test results per day
• Total: 400-700+ lab results requiring manual processing daily

The manual workflow was unsustainable:

• Staff retrieved printed faxes from the fax machine throughout the day
• Each result required manual review of the faxed document
• Staff transcribed every data point from the fax into the electronic system
• Multiple staff members handled the same documents, creating coordination challenges
• No automated verification of transcription accuracy
• No systematic tracking of which results had been processed

The pain points were affecting patient care:

• Hours or even days of delay between receiving results and entering them into the system
• Critical lab values sometimes overlooked in the pile of faxes
• Transcription errors introduced human factor risk into sensitive medical data
• No audit trail showing when results were received, reviewed, or entered
• Staff spent hours each day on repetitive data entry instead of patient care
• HIPAA compliance concerns with paper documents sitting in fax trays
• Impossibility of tracking processing status across hundreds of daily results

Without lab results processing automation, the facility needed a solution that could handle high-volume lab result processing while maintaining data accuracy, ensuring HIPAA compliance, and providing complete audit trails – all while keeping a human review step for the sensitive nature of medical data. Healthcare facilities nationwide face similar challenges with HIPAA compliance in faxed medical document processing.

Midnight Flow designed and implemented an end-to-end lab results processing system that eliminates manual transcription while maintaining the critical human oversight required for medical data.

The Challenge for Healthcare Automation: Lab results involve sensitive patient information where accuracy is paramount and HIPAA compliance is mandatory. The facility needed a solution that could handle 400-700 daily lab results at scale while ensuring medical staff could review and approve every result before it entered their EHR system.

Our Approach: We architected a workflow where AI handles the repetitive work – document retrieval, OCR extraction, data formatting – while intelligent logic pauses processing at the critical human decision point. When data has been extracted from a faxed lab result, the system generates a custom approval interface showing the extracted data alongside the original document. Designated medical staff receive email notifications, review for accuracy, approve or reject, and the workflow automatically continues based on their decision. This design – AI for efficiency, humans for judgment – is what healthcare automation requires. We implemented the solution on FlowRunner, a healthcare-focused platform with HIPAA-compliant infrastructure and built-in audit trails, ensuring the facility met all regulatory requirements while achieving the operational efficiency they needed

Automated Lab Results Processing Workflow:

1. Receive Fax: The system automatically retrieves incoming faxes in digital format from the fax service, eliminating the need for staff to monitor physical fax machines
2. OCR Extract: Advanced optical character recognition technology extracts lab result data from the faxed documents, including patient identifiers, test types, values, and reference ranges
3. Format Data: Extracted data is automatically formatted and structured according to the facility’s data standards, preparing it for system integration
4. Review UI: The formatted data is presented in a custom-built approval interface that displays lab results clearly and intuitively
5. Human Review: Designated approvers receive email notifications with secure links to the approval interface, where they can review lab results alongside the original faxed document
6. Approve: The approver reviews the extracted data for accuracy, can make any necessary corrections, and either approves or rejects the submission. This critical human review step ensures data quality for sensitive medical information
7. Finalize: Once approved, the data is automatically finalized in the Backendless database, ready for integration with the facility’s electronic health record system
8. Audit Log: Every step – receipt, extraction, review, approval/rejection, and any modifications – is logged with timestamps and user information for compliance purposes

Key components:

• Automated digital fax retrieval and monitoring
• OCR technology for data extraction from varied document formats
• Custom-designed approval interface for medical staff review
• Intelligent workflow logic for pause-review-continue orchestration
• Email notification system with secure approval links
• HIPAA-compliant infrastructure and data handling
• Complete audit trail logging (timestamps, user actions, data modifications)
• Integration with the facility’s EHR system for final data submission

The core design challenge was determining where to place the human review step. Too early, and you’re just digitizing a manual process. Too late, and inaccurate data could enter the system. Our solution: Place the human checkpoint immediately after data extraction but before system entry. This ensures:

1. AI handles all the tedious work: document retrieval, OCR processing, data formatting, and validation logic
2. Humans review only when data is ready: Medical staff see clean, formatted data alongside the source document—not raw faxes requiring transcription.
3. The approval interface is contextual: We designed the review UI to display patient identifiers, test types, values, and reference ranges intuitively. Staff can make corrections if OCR misreads something, then approve or reject with a single click.
4. Workflow continuity is automatic: Upon approval, the data flows immediately into the facility’s system with complete audit logging. No manual steps remain.
5. Compliance is built in: Every extraction, review, approval, and modification is logged with timestamps and user identity.

This architecture achieves what the facility required: AI efficiency at scale (400-700 daily results) with mandatory human validation, all while maintaining HIPAA compliance and operational speed. The workflow runs on infrastructure that supports the intelligent pause-and-resume logic required for healthcare operations – enabling medical staff to maintain oversight without becoming a bottleneck.”

The solution was built entirely on the FlowRunner and Backendless platforms, ensuring HIPAA compliance while providing the flexibility to customize the workflow to the facility’s specific requirements and regulatory needs.

The lab results processing automation transformed a manual, error-prone process handling hundreds of daily lab results into a streamlined, accurate system that processes results in minutes while maintaining the critical human oversight required for medical data. Staff who once spent hours transcribing fax documents now focus on patient care, while the facility gains the audit trail and compliance capabilities essential for modern healthcare operations.

Workflow Efficiency:

• Medical staff review time: 30-60 seconds per result (vs 5-10 minutes for manual transcription)
• Human oversight is maintained on 100% of lab results before system entry
• Zero data enters the EHR without explicit human approval
• Staff report higher confidence in data accuracy due to the side-by-side comparison interface
• Flexible approval routing enables the designation of different reviewers based on test type or urgency

Processing Speed:

• Before: Hours to days from fax receipt to system entry
• After: Minutes from fax receipt to approved data in the system
• Improvement: Processing time reduced by 95%+

Clinical Impact:

• Critical lab values are identified and entered faster, improving patient care response times
• Reduction in result processing delays that previously impacted treatment decisions
• Consistent, reliable processing regardless of daily volume fluctuations
• Real-time visibility into processing status for all pending results

“We wouldn’t have been comfortable with fully automated processing of lab results—medical data is too sensitive. Midnight Flow understood that and designed a solution that gives us the best of both worlds: automation handles the tedious extraction and formatting work, but our medical staff maintains oversight and approves every result before it enters the system. The approval interface they built makes reviews faster and more accurate than our old manual process. This is exactly what healthcare automation should be.”

The facility is now exploring how similar intelligent automation with human oversight can be applied to other healthcare workflows – including radiology report processing, specialist consultation intake, and prior authorization workflows.
