Resource Profile: Polaris Observation Profile Core

Official URL: https://fhir.apps.health/StructureDefinition/polaris-core-observation Version: 1.10.0
Draft as of 2026-05-26 Computable Name: PolarisCoreObservation

Polaris profile for the Observation resource, based on CA-Core. Represents measurements, tests, and simple assertions originating from source EMRs for aggregation.

Polaris Core Observation Profile

Overview

The Polaris Core Observation profile represents measurements, findings, and clinical results within primary care EMR systems. This profile supports a wide range of observations including vital signs, laboratory results, clinical assessments, and survey responses across the Polaris ecosystem.

Key Features

  • Flexible Value Types: Supports numeric, coded, text, boolean, and complex result types
  • LOINC Integration: Preferred coding system with fallback to source EMR codes
  • Component Support: Handles multi-part observations like blood pressure
  • Reference Ranges: Includes normal ranges for result interpretation
  • Status Tracking: Distinguishes preliminary, final, and corrected results

Clinical Categories

Common observation types include:

  • Vital Signs: Blood pressure, temperature, pulse, respirations, oxygen saturation
  • Laboratory: Chemistry panels, hematology, microbiology results
  • Imaging: Radiology and imaging findings
  • Survey: Patient questionnaires and assessments
  • Exam: Physical examination findings
  • Social History: Smoking status, exercise, substance use

Result Interpretation

The profile supports:

  • Categorical interpretations (high, low, normal, critical)
  • Reference ranges with age and gender specificity
  • Abnormal flags and clinical alerts
  • Trending and historical comparisons

Future Considerations

Potential enhancements being evaluated:

  • Method and device capture for quality metrics
  • Specimen details for laboratory observations
  • Performer qualifications and certifications
  • Delta checking and panic value alerts
  • Observation grouping and panels
