Polaris Core MedicationRequest Profile

Overview

The Polaris Core MedicationRequest profile represents prescriptions and medication orders within primary care EMR systems. This profile captures comprehensive prescription details including medication, dosage, route, frequency, and dispensing instructions across the Polaris ecosystem.

Key Features

• Contained Medication Resources: Uses contained Medication resources for comprehensive medication representation
• Structured Strength Modeling: Medication strength properly modeled in Medication.ingredient.strength
• Flexible Dosage Instructions: Supports both free-text sig and structured dosing
• Route Flexibility: Standard terminology with fallback to source EMR codes
• Dispense Management: Includes quantity, refills, and pharmacy instructions
• Prescriber Tracking: Links to practitioner who authored the prescription

Medication Representation Approach

Contained Medication Requirement

Polaris requires all medications to be represented as contained Medication resources. This approach provides:

1. Comprehensive Medication Details: The contained Medication resource captures all medication details including name, form, strength, and ingredients in a structured way.

2. FHIR Best Practices: Using contained resources follows FHIR best practices for prescription-specific medication details that don't exist independently.

3. Strength Modeling: Medication strength is properly modeled using the Medication.ingredient.strength element with numerator and denominator quantities.

Current Approach

The profile requires:

• medicationReference: Must reference a contained Medication resource
• Contained Medication: Must include a Medication resource in the contained array with appropriate details
• Structured Strength: Strength information captured in Medication.ingredient.strength

Prescription Components

Essential elements include:

• Medication Details: Drug name via CodeableConcept, strength via extension
• Sig Instructions: Complete dosage instructions as free text (required)
• Timing: Structured frequency and duration when available
• Route: How medication should be administered
• Quantity: Amount to dispense and number of refills

Clinical Workflow Support

The profile supports various prescription scenarios:

• New prescriptions from encounters
• Refill authorizations
• Medication changes and discontinuations
• Prescription renewals
• Standing orders and protocols

Status Management

Tracks prescription lifecycle:

• Active: Current prescriptions being filled
• Completed: Fully dispensed prescriptions
• Stopped: Discontinued medications
• On-hold: Temporarily suspended prescriptions
• Cancelled: Prescriptions that should not be filled

Future Considerations

Potential enhancements being evaluated:

• Substitution permissions and requirements
• Prior authorization tracking
• Indication for use documentation
• Complex dosing schedules and tapers
• Medication therapy management notes

• Key Elements Table
• Differential Table
• Snapshot Table
• Statistics/References
• All
