- 1 CDSSs are software-based tools designed to enhance medical decision-making by providing clinicians with relevant knowledge, patient-specific information, and other health-related data, ultimately aiming to support consistent and optimal patient outcomes .
- 2 While post-hoc explanation methods such as feature importance scores and counterfactual examples aim to make model decisions more transparent , these techniques remain grounded in correlations rather than causality and are associated with major shortcomings .
- 3 Methods such as structural causal models and directed acyclic graphs (DAGs) provide frameworks for representing causal assumptions , but establishing a valid causal structure requires substantial domain expertise to specify, evaluate, and refine these models .
- 4 During the SELECT phase, duplicates were removed and a three-step screening (title, abstract, and full-text) was conducted to retain studies at the intersection of decision support, human interaction, causal information methods, and clinical contexts.
Introduction
However, most existing AI-driven CDSSs rely on associative machine learning (ML) models that focus on pattern recognition rather than causal understanding . To address this gap, our study examines how causal ML can be integrated into CDSS and, in consequence, into medical decision-making by concentrating on human-AI collaboration through the user interface.
To address the research question, we used a design science research (DSR) approach , combining theoretical insights from existing literature with practical knowledge from the field.
Finally, we pursued an approach to formulate design principles (DPs) and design features (DFs) grounded in our DRs .
The search was limited to titles, abstracts, and keywords to ensure relevance, except for a full-text search on the AIS eLibrary due to technical constraints.
Methodology
Our analysis revealed three key tensions shaping the integration of causal ML into CDSS: (1) the use-frequency tension, (2) the control-compliance tension, and (3) the generalizationspecificity tension. To capture clinicians’ needs in the relevance cycle, we purposefully sampled physicians developing or testing ML-based CDSS in clinical practice and used snowball sampling after each interview to identify additional relevant participants within their networks .

Results & Findings

Building on these advancements, clinical decision support systems (CDSSs) leverage AI to assist clinicians in making evidence-based decisions by integrating medical knowledge and patient-specific data .

- Building on these advancements, clinical decision support systems (CDSSs) leverage AI to assist clinicians in making evidence-based decisions by integrating medical knowledge and patient-specific data .
- Although associative ML continues to be used and useful in AI-driven CDSS, these models can only identify correlations and cannot determine causality, making them unsuitable for.
- Consequently, to avoid misleading decision support and its explanations, correlation must be disentangled from causation .
- This challenge has motivated recent advances in causal ML, enabling models to reason about cause-effect relationships and quantify treatment effects .
Despite this promise, research on causal ML in CDSSs has primarily focused on model development (e.g., algorithms) for specific use cases with limited attention to how clinicians can effectively interact with such systems in practice .
This limitation is especially critical in clinical settings, where causal understanding is essential , and correlation-based explanations may risk prompting clinicians to misinterpret associations as causal, fostering illusions of causality .

Practical Applications
The emerging concept of causability-the degree to which explanations enable causal understanding for human experts-illustrates this gap: without explicit causal modeling, explanations of associative models may appear plausible yet mislead by implying causation where none has been established . ML-based -3, 4, 8, 9 SR.7.2 Prevents bias and data manipulation that could distort causal reasoning.
Their rigidity also hinders the integration of new scientific insights and expert knowledge, reducing the adaptive potential of causal ML and may even weaken the EU’s position as a hub for innovation, research, and health .
While this supports transfer across settings, it may limit the specificity and immediate applicability of the design guidance for any single application context.

The search was limited to titles, abstracts, and keywords to ensure relevance, except for a full-text search on the AIS eLibrary due to technical constraints. These layers were used to translate DRs into preliminary DPs and candidate DFs for subsequent design cycles.
Our analysis revealed three key tensions shaping the integration of causal ML into CDSS: (1) the use-frequency tension, (2) the control-compliance tension, and (3) the generalizationspecificity tension. For DR1, DR3, and DR8, the artifact should demonstrate acceptable usability (e.g., SUS \u2265 68).
