概括
整体模型在分类临床医生-患者情绪方面取得了最高的准确性,超过了深度学习和变压器模型. 这种方法增强了对改善医疗保健的患者医生互动的理解.
科学领域:
- 自然语言处理 (NLP) 是一种自然语言处理.
- 医疗保健中的机器学习
- 计算语言学 计算语言学
背景情况:
- 对临床医生与患者互动的准确情绪分析对于评估医疗保健质量和患者体验至关重要.
- 现有的研究缺乏对这种特定任务的先进机器学习模型的全面基准测试.
- 临床对话中的情感分类存在独特的挑战,原因是语言和上下文的细微差别.
研究的目的:
- 在医生与患者的咨询中,对深度学习,变压器和整体模型进行三类情绪分类 (低/中/高) 的基准测试.
- 解决临床领域内对情绪分析模型标准化评估的差距.
- 确定最有效的模型架构来分析匿名医生与患者对话中的情绪.
主要方法:
- 利用公开可用的3325个匿名医生与患者咨询的数据集.
- 评估的长期短期记忆 (LSTM),双向LSTM (BiLSTM),卷积神经网络 (CNN),CNN-LSTM,以及来自变压器的双向编码器表示 (BERT).
- 还使用分层五倍交叉验证测试了一种整体模型 (对逻辑回归,随机森林和支持矢量分类器进行硬投票).
主要成果:
- 整体模型实现了最高的精度 (75.5% ± 0.5%),超过了包括BERT在内的单个模型 (66.98% ± 0.6%).
- 整体表现出强大的高严重性相互作用检测 (F1得分:90.8%±1.3%),尽管低严重性相互作用的分类仍然具有挑战性.
- 对于低严重度的相互作用,BERT提供了最高的精度 (65.5%±1.0%),整体则改善了回忆 (58.7%±1.0%).
结论:
- 合体学习为临床医生与患者对话中的三类情感分类提供了最强和最平衡的表现.
- 像BERT这样的变压器模型为挑战性较低的案件提供了宝贵的精度,补充了整体方法.
- 可解释性分析提高了透明度,支持了临床应用;未来的工作应该探索多式联络和保护隐私的模型.

Patient-centered Care
2.9K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Techniques of Therapeutic Communication II: Focusing, Paraphrasing, and Summarizing
10.8K
Focusing involves centering a conversation on a message's critical elements or concepts. Focusing is valuable if the talk is vague or patients begin to repeat themselves. Sometimes, when patients are asked about their symptoms, they may go off-topic and try to tell their entire life story. Respectfully, the nurse should bring the conversation back into focus.
This therapeutic technique can also be used when a patient brings up pertinent information during a health-related conversation. The...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Current Trends in Nursing II
3.3K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...
