Implementation Strategy

Phase 1: Assessment & Planning (Weeks 1-2)

Workflow Mapping:

Critical Questions:

1. What clinical workflows need EHR integration?
2. What data elements are required for each workflow?
3. What are the performance requirements (latency, volume)?
4. Are there custom EHR fields or workflows?
5. What’s the anticipated message volume (current & 2 years)?

Workflow Categorization:

Standard Workflows (Redox candidates):

• Patient registration and demographics
• Appointment scheduling
• Lab result notifications
• Clinical document retrieval
• Basic medication lists

Critical Workflows (Direct API candidates):

• Real-time medication reconciliation
• OR scheduling and preference cards
• Provider schedule management
• High-frequency monitoring data
• Custom clinical workflows

Volume Analysis:

Calculate Daily Message Volumes:

ADT events: [number] × 3 messages each = [total]
Lab orders: [number] × 2 messages = [total]
Appointments: [number] × 2 messages = [total]
Results: [number] × 1 message = [total]

Total daily messages: [sum]
Peak hourly: [total] ÷ 10 (assume 10-hour day)
Peak per second: [hourly] ÷ 3600

Example (500-bed hospital):

• ADT: 500 daily × 3 = 1,500 messages
• Labs: 1,000 daily × 2 = 2,000 messages
• Appointments: 2,000 daily × 2 = 4,000 messages
• Results: 1,500 daily × 1 = 1,500 messages
• Total: 9,000 messages/day
• Peak hourly: 900 messages
• Peak per second: 0.25 messages
• Verdict: Well within Redox limits (20/second)

Phase 2: Architecture Design (Weeks 2-3)

Integration Pattern Selection:

Decision Framework:

For Each Workflow:

1. Message volume: <1,000/day → Redox | >10,000/day → Consider direct

Common Pitfalls & Solutions

Pitfall 1: Treating Redox as Complete Solution

Problem: Organizations implement Redox and assume all integration needs are solved, then hit performance or functionality walls when scaling.

Solution:

• Plan hybrid architecture from day one
• Identify critical workflows requiring direct integration
• Budget for both Redox and direct approaches
• Design abstraction layer supporting multiple integration types

Pitfall 2: Insufficient Error Handling

Problem: Simple error handling that doesn’t account for healthcare integration complexity leads to lost messages and data inconsistencies.

Solution:

• Implement comprehensive retry logic
• Build dead letter queue for failed messages
• Create alerting for error thresholds
• Develop reconciliation processes
• Regular error pattern analysis

Pitfall 3: Poor Resource Tracking

Problem: Not maintaining proper patient identifier mapping across systems causes duplicate records and data quality issues.

Solution:

• Build Master Patient Index (MPI)
• Implement fuzzy matching algorithms
• Regular duplicate detection
• Manual review workflow for uncertain matches
• Audit and correction processes

Pitfall 4: Inadequate Performance Planning

Problem: Not anticipating future message volumes leads to performance bottlenecks when scaling.

Solution:

• Calculate 2-year volume projections
• Load test at 10x expected volume
• Plan for peak periods (Monday mornings, flu season)
• Implement caching strategies
• Monitor performance metrics continuously

Pitfall 5: Over-Engineering

Problem: Building overly complex hybrid architecture when Redox alone would suffice, wasting time and resources.

Solution:

• Start with Redox for standard workflows
• Add direct integration only when needed
• Measure actual performance before optimizing
• Use simplest solution that meets requirements
• Iterate based on real usage data
