Bottom Line

This paper from the Fraunhofer Institute for Cognitive Systems presents a methodologically structured approach to safety design for clinician-AI interaction in computer-aided diagnosis, using System-Theoretic Process Analysis (STPA) to identify hazards and derive actionable design guidelines. The work addresses a genuine and underserved problem: the inadequacy of current regulatory frameworks in managing the human-AI interface in clinical diagnostics. The identification of automation bias and misinterpretation of AI explanations as primary hazard categories is clinically credible and consistent with the broader patient safety literature. The proposed explainability consistency metric is conceptually innovative. However, this remains a theoretical framework paper. There is no empirical clinical validation, no patient outcome data, no usability testing with clinicians, and no quantitative precision metrics. The expert derivation process lacks transparency. For Australian clinicians and health technology governance teams, this framework offers a useful conceptual scaffold for structuring AI safety assessments and informing TGA SaMD submissions, but it cannot be adopted as clinical guidance without prospective validation in real-world settings. It is best regarded as a starting point for institutional AI governance work rather than evidence-based clinical practice guidance.

Evidence: Weak

Key Findings

  • P Value: Not reported

  • Effect Size: Not applicable — no empirical effect size reported; this is a framework development study

  • Primary Outcome: Derivation of a set of actionable, STPA-grounded safety design guidelines for clinician-AI interaction in CAD systems, addressing hazards including automation bias and XAI misinterpretation

  • Nnt Or Sensitivity: Not applicable — no diagnostic accuracy, NNT, or hazard ratio data presented. The proposed explainability consistency metric is described as a quantitative indicator but no sensitivity/specificity values for detecting unreliable explanations are reported

  • Confidence Interval: Not reported

Clinical Application

The framework is conceptually implementable but requires substantial institutional resources for operationalisation: dedicated human factors expertise, iterative GUI prototyping, XAI method integration, and ongoing safety monitoring infrastructure. Feasibility in smaller health services or primary care settings is not addressed. The STPA methodology requires specialist training not routinely available in clinical teams. Australia's Therapeutic Goods Administration (TGA) has published guidance on Software as a Medical Device (SaMD) and AI/ML-based medical devices, requiring post-market surveillance and risk management aligned with ISO 14971. The STPA-based framework described in this paper could theoretically complement TGA SaMD regulatory submissions by providing structured hazard documentation. However, the paper does not reference TGA guidance, the Australian Digital Health Agency's AI frameworks, or RACGP digital health standards. Australian health services considering AI-enabled CAD deployment should treat this framework as a supplementary methodological resource requiring local contextualisation, regulatory alignment with TGA requirements, and validation within Australian clinical workflows before adoption. The PBS does not currently fund AI-assisted diagnostic services as a standalone item, and MBS item numbers for AI-augmented diagnostics remain limited and evolving. Clinicians in any specialty using AI-enabled CAD systems for diagnostic decision support, particularly in radiology, pathology, dermatology, and cardiology where CAD tools are most mature. Most immediately relevant to clinical informaticists, health technology assessment teams, and clinical AI governance committees.

Abstract

Ensuring the safety of Artificial Intelligence-enabled Computer-Aided Diagnosis systems is critical because diagnostic errors can have serious consequences for patient care. However, existing regulatory and risk management frameworks often do not sufficiently address the complex socio-technical interactions between clinicians and Artificial Intelligent systems, leaving key human-centered safety challenges underexplored. This paper presents a systematic and human-centered approach to deriving safety design guidelines for clinician-Artificial Intelligence interaction in Computer-Aided Diagnosis systems using System-Theoretic Process Analysis. Through this analysis, we identify critical hazards associated with clinician-Artificial Intelligence collaboration, including automation bias on system recommendations, and misinterpretation of explanations. Based on the identified unsafe control actions, we formulate a set of actionable and traceable safety design guidelines that promote transparency, coherent explanations, and calibrated trust in Artificial Intelligence-assisted decision-making. To bridge safety analysis and system design, the proposed guidelines are operationalized within a Computer-Aided Diagnosis interaction framework. The framework includes a safety-oriented Graphical User Interface that integrates multiple explanation methods and interactive mechanisms to promote clinician engagement. Furthermore, we introduce a safety-oriented evaluation approach that uses consistency across multiple explanation methods as a quantitative indicator of potentially unreliable or ambiguous explanations. By linking System-Theoretic Process Analysis, interaction design, and explainability evaluation, this work provides a unified and reusable framework for improving the safety and reliability of Artificial Intelligence-driven Computer-Aided Diagnosis systems.
