Bridging the Gap: Human Factors Drive AI Impact in Surgery
This article highlights two contrasting studies on AI-assisted surgical video analysis, revealing that AI's impact hinges not just on accuracy, but critically on human-computer interaction (HCI) factors like trust, explainability, and user expertise. While AI boosted accuracy in both, expert adoption varied significantly based on whether AI offered transparent explanations. The commentary underscores the need for structured evaluation frameworks like IDEAL and DECIDE-AI to integrate human factors systematically into surgical AI design and deployment.

Accuracy increase for novices with unexplained AI assistance (Khan et al.)
The Khan et al. study on pituitary surgery found that novices benefited most from AI assistance, improving accuracy from 66% to 79%. Experts, however, saw more modest gains (73% to 75%). This disparity arose because the AI provided only a silent, unexplained recommendation, which novices, with less baseline knowledge, tended to trust more readily, aligning their decisions to the algorithm. This highlights how an absence of explanation can lead to uncritical trust from less experienced users.

Accuracy increase for experts with explained AI assistance (Williams et al.)
Conversely, the Williams et al. aneurysm study showed expert neurosurgeons experiencing a marked improvement in accuracy (77% to 92%), outpacing novices (75% to 86%). Here, participants received accuracy metrics and heatmaps showing where the AI focused, offering a 'glimpse into the black box.' For experts, this additional context helped validate their instincts or nudge them towards trust in tougher scenarios. This demonstrates that explainable AI significantly enhances expert adoption and performance.

Post-market Surveillance & Outcome Measurement
The contrasting outcomes underscore a crucial point: AI in the operating room is a complex intervention. Simply deploying an accurate algorithm is insufficient if core human-computer interaction (HCI) factors are not addressed. Trust, explainability, usability, and perceived workload critically shape how humans perceive, trust, and ultimately utilize AI effectively and safely. Frameworks like IDEAL and DECIDE-AI offer a roadmap for systematically integrating HCI factors throughout the AI lifecycle.
Why Explainable AI Matters in Radiology
Similar to surgery, radiology benefits significantly from explainable AI. Interfaces that expose model rationale (e.g., heatmaps) have been shown to increase clinicians' agreement with AI and shape trust. This echoes the findings in the surgical studies, emphasizing that transparency is key to effective human-AI collaboration across medical specialties, especially when clinicians need to validate their own expertise against AI recommendations. This avoids over-reliance and improves diagnostic confidence.
However, over-reliance remains a concern. Studies in ophthalmology and breast cancer diagnosis have shown that high confidence in AI systems, even with explainable features, can lead to reduced performance if clinicians over-rely on incorrect AI outputs. This highlights the need for careful calibration of human-AI alignment and continuous real-world outcome assessment.
