Medx Diagnostic Reasoning
We support clinical thinking for faster, safer diagnosis and better health outcomes.

Our Approach

Medx is a visual reasoning platform for physicians that offers diagnosis decision support at the point of care.

It combines a broad medical knowledge base, a fast, patient-adaptive reasoning algorithm and an award-winning, patent-pending user interface.

Fast responsive data entry enables rapid documentation of relevant information.


Visual reasoning interface activates and supports clinical thinking and decision-making.


Important diagnoses to consider are highlighted, along with appropriate next steps.

It's streets ahead of anything else that's out there. It's almost too good.

This is ‘next generation’ decision support, much more closely mirroring the way clinicians tackle diagnostic problems.

One patient had a previous diagnosis of chronic diverticulitis so everyone focused on that. Medx suggested a kidney stone, which turned out to be correct. That was really impressive.

How we work

Unlike in traditional AI (artificial intelligence), the emphasis of our work is not on replacing human thinking, but on supporting the clinician’s innate cognitive skills with the goal of both ensuring and fostering cognitive excellence. We call this Cognostics.

We use insights from the cognitive sciences

Our approach is informed by the latest insights from the cognitive sciences and we benefit from a close collaboration with the Parmenides Foundation in Munich, incorporating aspects of their theories of Constellatory Logic into what we do.

We support clinical reasoning with visual tools

Our award-winning, patent-pending, visual tools support the clinical reasoning process at each step, using great design to enable powerful improvements in thinking and decision-making.

We combine expert knowledge with real world data

Our content is based on best available medical evidence and expert insight. We then combine this knowledge base with validated, real-world data, to continuously refine our reasoning support and provide users with data-driven insights.

We focus on improving health outcomes

Each aspect of the medx platform has been built with one ultimate goal in mind - improving patient health outcomes. We aim to achieve this by enabling earlier diagnosis, accurate patient stratification, outcomes measurement, benchmarking and improvement.
