The Impact of Regional Block Presence on Large Language Model-Based Postoperative Analgesia Recommendations in Abdominal Surgery: A Comparative Study Using Real-World Patient Data
This study investigates how LLM-based AI systems integrate critical perioperative context, specifically the presence of a regional block, when generating postoperative analgesia recommendations for abdominal surgery patients. Utilizing real-world data, the research compares AI outputs from ChatGPT, Gemini, and Copilot against expert assessments and actual clinical practice, revealing nuanced contextual awareness but limited practical concordance.

Statistical Analysis (Regression & Kappa)
Our methodology involved a prospective, observational, and comparative study design, ensuring real-world patient data informed the AI evaluations. Patients were divided into groups based on the presence or absence of a regional block, and standardized clinical scenarios were presented to three leading LLM-based AI systems. Expert anesthesiologists then independently assessed the AI-generated recommendations for clinical appropriateness and agreement with actual practice.
98% Reduction
in additional regional block recommendation by ChatGPT when a block was already present (aOR 0.02, p < 0.001).
| AI System | Opioid Recommendation Agreement (%) | Multimodal Analgesia Agreement (%) | Regional Block Recommendation Agreement (%) |
|---|---|---|---|
| ChatGPT | 55.7 | 82.1 (Universal recommendation, low specificity) | 85.7 (Strong reduction in re-recommendation when block present) |
| Gemini | 52.9 | 82.1 (Universal recommendation, low specificity) | 83.6 (Complete separation: recommended only without existing block) |
| Copilot | 58.6 | 82.9 (Demonstrated some variability) | 90.0 (Reduced likelihood of re-recommending block when present) |
Key findings indicate that while AI systems show contextual awareness regarding existing regional blocks, this doesn't consistently translate into alignment with real-world practice, particularly for opioid use. Multimodal analgesia was often universally recommended, suggesting limited differentiation by AI.
Contextual Awareness vs. Clinical Concordance
Our study highlights a critical dichotomy: while LLM-based AI systems demonstrate partial contextual awareness of regional anesthesia, this awareness does not consistently translate into high concordance with real-world clinical practice. For instance, Gemini uniquely identified the absence of a regional block as a strong cue to recommend one, showcasing a level of contextual understanding. However, for more nuanced domains like opioid use, AI recommendations often deviated from clinical decisions, reflected in low Cohen's kappa values.
This suggests that current AI models excel at pattern recognition for salient clinical interventions but struggle with the inherent heterogeneity of clinical practice and patient-specific factors in domains requiring subtle judgment. The findings underscore the role of AI as an adjunctive decision support tool, rather than a substitute for expert clinician judgment, emphasizing the need for transparent, context-aware integration guided by human oversight.
The implications for enterprise AI adoption in healthcare are significant. While AI can streamline certain decision-making processes, its deployment requires careful validation against real-world outcomes and a clear understanding of its limitations, especially where patient safety and individualized care are paramount. Continuous human oversight and iterative refinement of AI models will be crucial for successful integration.
