AI总结:

针对术前患者咨询受限问题,提出安全本地优先的LENOHA系统,用高精度分类器路由临床查询并返回经审核的FAQ逐字答案,在两领域评估中准确率达0.983,能耗远低于本地小模型,兼顾隐私、可持续性与公平部署。

摘要:

等待侵入性操作的患者常有未得到解答的术前问题,但时间紧张的工作流程和隐私限制制约了个性化咨询。我们提出LENOHA(低能耗、无幻觉、不让任何人掉队架构),这是一个安全优先、本地优先的系统,通过高精度sentence-transformer分类器路由输入,并针对临床查询返回临床医生策划的FAQ中的逐字答案,在临床路径中消除了自由文本生成。我们使用专家评审的验证集(每个领域n=400)进行阈值确定,并使用独立测试集(每个领域n=200),在两个领域(拔牙和胃镜检查)开展评估。在四个编码器中,E5-large-instruct(560M)实现了0.983的总体准确率(95%置信区间0.964-0.991)、AUC为0.996,总共有7个错误,在该任务上与GPT-4o的表现无统计学差异;Gemini在该测试集上没有错误。能耗记录显示,非生成式临床路径每次输入消耗约1.0毫瓦时,而本地8B SLM的闲聊回复每次消耗约168毫瓦时,差异约为170倍,同时在单台本地GPU上保持约0.10秒的延迟。这些结果表明,通过逐字返回经过审核的FAQ答案,临床路径从结构上避免了接近前沿的判别错误和生成诱导错误,支持在带宽有限的环境中实现隐私保护、可持续性和公平部署。

英文摘要:

Patients awaiting invasive procedures often have unanswered pre-procedural questions; however, time-pressured workflows and privacy constraints limit personalized counseling. We present LENOHA (Low Energy, No Hallucination, Leave No One Behind Architecture), a safety-first, local-first system that routes inputs with a high-precision sentence-transformer classifier and returns verbatim answers from a clinician-curated FAQ for clinical queries, eliminating free-text generation in the clinical path. We evaluated two domains (tooth extraction and gastroscopy) using expert-reviewed validation sets (n=400/domain) for thresholding and independent test sets (n=200/domain). Among the four encoders, E5-large-instruct (560M) achieved an overall accuracy of 0.983 (95% CI 0.964-0.991), AUC 0.996, and seven total errors, which were statistically indistinguishable from GPT-4o on this task; Gemini made no errors on this test set. Energy logging shows that the non-generative clinical path consumes ~1.0 mWh per input versus ~168 mWh per small-talk reply from a local 8B SLM, a ~170x difference, while maintaining ~0.10 s latency on a single on-prem GPU. These results indicate that near-frontier discrimination and generation-induced errors are structurally avoided in the clinical path by returning vetted FAQ answers verbatim, supporting privacy, sustainability, and equitable deployment in bandwidth-limited environments.
