Explainable AI & Quantified Uncertainty in Clinical Decision Support
How The Evidence Company goes beyond the black box - delivering traceable, trustworthy AI that clinicians can rely on.
The Problem
Why Standard AI Falls Short in Clinical Settings
Some artificial intelligence (AI) approaches, such as the large language models (LLMs) that power the now widely popular chatbots, are so complex that we are not able to determine how the AI produces its output. That means you can ask it a question and even though it may be able to answer it, no one can tell exactly why it produced the answer it did.
Standard chatbots may make mistakes, providing answers that are incorrect and not grounded in real-world data. This opaqueness means that with other solutions we cannot easily guarantee correctness, trace model behaviour, audit the models and make corrections where necessary.
At The Evidence Company, we believe that to truly trust these models with medical data, we need to use explainable AI (XAI). XAI focuses on providing understandable reasons for why a system arrived at a particular decision or output.
The Core Gaps in Standard Clinical AI
- No traceable reasoning or source attribution
- Confidence scores that are uncalibrated or absent
- Hallucinated outputs presented with false certainty
- Black-box decisions with no audit trail
- No workflow integration for clinician review

What Is Explainable AI?
Explainable AI (XAI) focuses on providing understandable reasons for why a system arrived at a particular decision or output. Let's see how this works for you:
You're in the Driver's Seat
Configurable agents allow you to define the behaviour of the conversation with your patients. You define the topics of the conversation, what questions to ask and what information the AI needs to be aware of. This empowers you to set out the conversation criteria and understand how the agents will behave.
Transparent Behaviour
Our AI combines your structured guidance with conversational flexibility. It dynamically adapts to user responses, follows conditional workflows when needed and allows patients to ask questions, all while staying focused on the core objectives you outline.
Increased Confidence
With this level of configuration, the AI's behaviour becomes transparent and our extensive testing increases confidence that the agent adheres to your requirements.
Goal-Oriented Agents
You can build a goal-oriented agent that collects the exact required information from the patient — like medications, allergies, or past procedures — and specify a checklist of concerns to be raised as a matter of urgency.
Foundation
Evidence at the Heart of What We Do
Every decision made, every question asked and every response given can be traced to a source. This means that as conversations progress, you can trace exactly what patients said that lead to each line of discussion, every piece of medical history taken and any concerns raised. The AI's behaviour and the reports provided back to clinicians is grounded in everything that patients say, all of which we make available to you.
When patients ask questions, answers are either drawn from verifiable sources that you can provide or it is made explicit when we are unable to provide for the answer. With our upcoming clinician chat functionality, clinicians can ask questions to gain even deeper insights into patient conversations, providing insights from extensive knowledge bases grounded in the medical literature.
You can ground the AI agent in your own knowledge bases. For example, you can provide pre- or post-procedure guidance that our AI agent will refer to throughout the conversation.
Grounded Knowledge in Practice
Patient-Grounded Responses
Every piece of medical history taken and any concerns raised are traceable to what patients said - all made available to you.
Verifiable Sources
Answers are drawn from verifiable sources you provide, or it is made explicit when we are unable to provide for the answer.
Your Own Knowledge Bases
Provide pre- or post-procedure guidance that our AI agent will refer to throughout the conversation, ensuring patients always have the right information.
The Hallucination Problem
Handling Uncertainty
We know that medical data is inherently complex, with patient answers that are incomplete or conflicting and general guidelines that are not always clear on how to apply to specific scenarios. We do not shy away from this but instead embrace it.
Conflict-Tolerant XAI
Our use of conflict-tolerant XAI approaches allows us to argue with conflicting pieces of evidence to highlight contradictions and resolve them where we can.
Full Context for Better Decisions
Where patients and clinicians need answers, we believe providing full context of the problem and where disagreements may arise allows for more informed decisions to be made. We put the power back in your hands.
Balanced, Evidence-Based Responses
For example, if a patient asks whether a colonoscopy or stool test is best for them, our system provides a balanced response that surfaces multiple evidence-based perspectives - explaining the clinical reasoning behind each option.
Raising Concerns with Clinicians
We will raise any patient concerns about their procedure with their clinician. By providing full context, we allow patients and clinicians to make more informed decisions together.
Our Platform
A Different Architecture for Clinical AI
Our platform is purpose-built to address the fundamental limitations of standard LLMs in healthcare. Rather than relying on generative models alone, we combine structured clinical knowledge, retrieval-grounded reasoning, and conflict-tolerant XAI - producing outputs that clinicians can interrogate, verify, and trust.
Every output generated by our platform is anchored to a verified source, grounded in everything that patients say, and presented with full reasoning transparency. This is not a feature add-on - it is the architectural foundation of how our system works.
Platform Differentiators
How Our Platform Stands Apart
Traceable Source Attribution
Every decision made, every question asked and every response given can be traced to a source. Clinicians can trace exactly what patients said that led to each line of discussion, every piece of medical history taken and any concerns raised — supporting informed decision-making and governance compliance.
Configurable Agent Behaviour
You define the topics of the conversation, what questions to ask and what information the AI needs to be aware of. You can design how the patient's information is reported back to you, so that the most important information is surfaced as quickly as possible.
Conflict-Tolerant Uncertainty Handling
Our use of conflict-tolerant XAI approaches allows us to argue with conflicting pieces of evidence to highlight contradictions and resolve them where we can - preventing fabrication of clinical information even in ambiguous scenarios.
Step-by-Step Reasoning Transparency
Clinicians can inspect the reasoning chain behind any recommendation — seeing exactly which evidence was retrieved, how it was weighted, and what logic pathway led to the output. Full auditability at every step.
Healthcare Use Cases
Explainable AI in Action: Clinical Applications
Our platform's explainability and conflict-tolerant uncertainty handling translate into tangible clinical value across a range of high-stakes healthcare scenarios.
Pre-Procedure History Collection
Build a goal-oriented agent that collects the exact required information from the patient — what medications they're on, what allergies they have, what past procedures they have had - surfacing the most important information to clinicians as quickly as possible.
Patient Question Answering
Answers are drawn from verifiable sources you provide, or it is made explicit when we are unable to provide for the answer. Patients always have the information they need available to them at all times.
Clinician Chat & Deep Insights
With our upcoming clinician chat functionality, clinicians can ask questions to gain even deeper insights into patient conversations, providing insights from extensive knowledge bases grounded in the medical literature.
Urgency Flagging & Risk Escalation
Specify a checklist of concerns that need to be raised - for example if the patient does not tolerate sedation well - and we will highlight these to you as a matter of urgency.
