Business Context
Artificial intelligence and machine learning tools applied to clinical decision support, including risk prediction models and diagnostic assistance tools, can achieve strong predictive performance, sometimes exceeding traditional rule-based clinical decision tools, by learning complex patterns from large datasets. However, the most predictively powerful models are often the least explainable, offering a risk score or recommendation without a clear, clinically interpretable rationale, and clinicians, appropriately cautious about acting on a recommendation they cannot understand or verify, often show reduced trust in and adoption of high-performing but poorly explainable tools, limiting their real-world clinical impact regardless of their technical accuracy.
Healthcare TRIZ Resolution
Rather than choosing uniformly between maximally performant but opaque models and less performant but fully interpretable models, the resolution pairs high-performance predictive models with a dedicated explanation layer, using established interpretability techniques to surface the specific clinical factors most influential in a given prediction alongside the prediction itself, presented to clinicians in familiar clinical language rather than raw model output, allowing clinicians to evaluate the plausibility of the underlying reasoning even when the full model architecture remains complex.
Applicable TRIZ Principles
Principle 24 – Intermediary Introduce a dedicated explanation layer as an intermediary between the underlying model and the clinician, translating model output into clinically interpretable reasoning.
Principle 40 – Composite Materials Combine a high-performance predictive model with an interpretability layer rather than sacrificing performance for a simpler but less accurate model.
Principle 25 – Self-Service Allow clinicians to independently evaluate the plausibility of presented reasoning rather than requiring them to trust the model output on faith.
Expected Outcome
Preserved model predictive performance
Increased clinician trust and adoption
Better clinical verification of recommendations
Reduced automation bias risk
Decision Indicators
Early indicators that this contradiction is limiting organizational performance include:
Low clinician adoption or override rates for AI-driven clinical decision support tools despite strong measured predictive performance
No interpretability or explanation layer accompanying model-generated predictions or recommendations
Clinicians reporting they do not understand or trust the reasoning behind AI-generated recommendations
Model outputs presented as raw scores or classifications without translation into clinically familiar language
No structured process allowing clinicians to flag and review cases where model reasoning appears clinically implausible
Monitoring these indicators helps clinical informatics leadership identify whether explainability gaps, rather than model accuracy itself, are limiting the real-world clinical value of decision support tools.
