World-class medical diagnostic engine

At Infermedica, we aim to connect people with the medical services they need. This is possible thanks to our AI‑powered diagnostic engine that precisely analyzes patients' health.

HOW IT WORKS

AI-led medical interview

Infermedica’s technology draws conclusions from patient data to construct personalized medical interviews on the fly. Our AI asks the right questions to gather supplementary health information, better understand patients' health, and give appropriate recommendations. The process consists primarily of the following:

  1. The personalized patient interview starts with gathering initial symptoms, risk factors, and demographic data. Additional input regarding the symptoms' occurrence or severity makes the engine even more precise.

    • The engine is backed with a comprehensive library of thousands of medical conditions
    • It covers multiple medical specialties, including pediatrics
  2. The diagnostic engine uses initial evidence to construct a personalized medical interview based on probabilistic models and reasoning techniques. It was developed by our data scientists, who collaborated closely with medical experts.

    • Algorithms follow the rules physicians use to generate a differential diagnosis
    • The engine verifies various conditions at once and is more effective than a fixed rule-based system
  3. Infermedica’s AI knows exactly when to stop asking questions. The diagnostic engine observes correlations between patients’ symptoms and hundreds of diseases. With every answer from the user, it becomes more confident about the most probable conditions.

    • It’s one of the shortest pre-interviews on the market
    • Questions are generated dynamically during the interview
  4. Finally, the diagnostic engine presents the most probable causes of the symptoms, which are paired with the suggested level of care. All recommendations are adjusted to the individual patient’s case.

    • Our triage recommendations are based on a 5-level scale (self-care, consultation, consultation 24h, emergency, ambulance)
    • We provide guidance for level of care, recommended medical specialist, communication channels, and more

Foundations of AI

Continuous improvement

Machine learning

Based on the observation of a powerful database, model data (Supervised ML), and feedback loop, the system identifies patterns, statistical facts, and learns to make better decisions and conclusions.

  • Evidence-based literature
  • Feedback loops with clients
  • Large anonymized data sets

Probabilistic modeling

Scientists, engineers, and doctors have contributed to our algorithms and probabilistic models. These parts of our engine are based on modified Bayesian networks and machine learning methods.
