Platform
Pharos is a Clinical Intelligence platform that grows with you
Health systems spend tens of millions of dollars and thousands of clinical hours extracting complex data from charts today. Pharos automates that work with clinical-grade accuracy at AI scale. One implementation supports clinical reasoning use-cases across your system.
Architecture
The Pharos Engine is the foundation of our products: integrating complex data sources, reasoning over clinical definitions, and answering with full interpretability.
Read
Pharos handles clinical documentation in any form, from any source system. Pull in external Oncology system data alongside scanned, handwritten notes and reason across the whole patient journey.
Interpret
Pharos follows detailed abstraction instructions to the letter, with verifiable reasoning, context and source evidence. Hallucination guardrails mean data you can trust from internal analysis to critical reporting.
Answer
All abstracted outputs are paired with detailed natural-language reasoning and source evidence, linked back to the chart, allowing lightening-fast human review for high-consequence use-cases.
Responsible AI
Designed for the most complex data extraction tasks where accuracy is critical
Clinical-grade accuracy, independently validated
In an independent study with the College of American Pathologists, Pharos hired an outside firm to abstract thousands of real-world patient records on challenging quality measures, achieving 95.7% accuracy – statistically indistinguishable from experienced human abstractors.
Fully explainable outputs
See the full decision path to every answer: the clinical logic applied, the evidence used, the alternatives considered and rejected, and any conflicts found in the chart. Low-confidence outputs are clearly surfaced for manual review.
Cutting-edge neurosymbolic AI
Hallucination risk is highest when AI is asked broad, open-ended questions. Pharos breaks each clinical question into atomic decisions, then walks through the abstraction logic step by step. This neurosymbolic approach keeps the AI's job narrow and every output grounded in chart evidence.
Built for clinical nuance
Real medical records are messy. Notes are copied
forward, clinicians disagree, and evidence is spread across encounters and specialties. Pharos accounts for timing, source hierarchy, and clinical significance, with the depth you'd expect from an experienced abstractor.
Clinical experts review outputs against real-world records, helping refine edge cases and improve how the system handles complex documentation over time.
