World-class medical inference engine
At Infermedica, we aim to connect people with the medical services they need. This is possible thanks to our AI‑powered inference engine that precisely analyzes patients' symptoms.
HOW IT WORKS
AI-led medical interview
Infermedica’s technology draws conclusions from patient data to construct dynamic medical interviews on the fly. Our AI asks the right questions to gather supplementary health information, better understand patients' state of health, and give appropriate recommendations. The process consists primarily of the following:
-
The 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
-
The inference engine uses initial evidence to construct a dynamic 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 of differential diagnosis that physicians use to interview the patient
- The engine verifies various conditions at once and is more effective than a fixed rule-based system
-
Infermedica’s AI knows exactly when to stop asking questions. The inference 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
-
Finally, the inference engine presents the most probable causes of the symptoms, which are paired with the suggested level of care. Combined with the answers of the intelligent interview, recommendations are individual to each situation.
- Our triage recommendations are based on a 5-level scale (self-care, consultation, consultation 24h, emergency, ambulance)
- We provide recommendations for the level of care, type of medical specialist, communication channels, and more
Our engine’s abilities
Complexity
The inference engine is able to analyze numerous symptoms, conditions, risk factors, and demographics at once.
Adaptability
Small bits of evidence can make a big difference. Our engine adapts as it learns about patients’ complaints.
Instant results
Our engine can investigate multiple conditions in real time and provide recommendations in a matter of minutes.
Dynamic logic
Our AI asks fully dynamic questions—there is no fixed logic or prescribed path.
Blazing speed
It accelerates to reach high performance with an unmatched query response time of ~0.1 s!
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 reach better intelligent outcomes.
- 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.
