## Summary

A study by Qilu Hospital of Shandong University found that DeepSeek’s reasoning-enhanced model, paired with a retrieval-augmented guideline knowledge base, outperformed simpler versions in preoperative assessments for hip and knee replacements. The research, published in *Arthroplasty*, tested four model configurations against 292 anonymized patient records, focusing on elderly patients with chronic conditions like diabetes and cardiovascular disease. The best-performing setup—DeepSeek-R1 plus the knowledge base—boosted junior physicians’ accuracy in surgical tolerance judgments from 76% to 88% and improved overall assessment odds by 58%, according to the study led by Haibo Wu and Qunshan Lu. However, the authors warned that models remain imperfect tools and must be used under senior physician oversight to avoid over-reliance on automated outputs. The knowledge base, built from 21 perioperative guidelines, improved risk prediction accuracy to 87.2% for the R1 model, though all configurations struggled with rare complications like poor wound healing.

## Key points

- DeepSeek-R1 with a guideline knowledge base improved junior doctors’ surgical tolerance accuracy from 76% to 88% in a study of 292 patient records
- Researchers paired the model with a retrieval-augmented knowledge base of 21 perioperative guidelines to enhance clinical decision-making
- Authors caution that models should only assist, not replace, senior physician judgment in high-stakes preoperative assessments

## Why it matters

This study demonstrates how RAG-enhanced AI models can assist junior clinicians in complex, high-stakes medical decisions, potentially reducing errors in preoperative assessments for joint replacements. The findings could accelerate adoption of AI decision-support tools in orthopedics, though human oversight remains critical.
