自然言語処理と深層学習を用いた自家乳房再建における患者の感情分析
Aesthetic surgery journal. Open forum
|December 26, 2025
まとめ
患者レビューによると、乳房再建において、横行腹直筋皮弁(TRAM)および広背筋皮弁(LD)と比較して、深部下腹部穿通枝皮弁(DIEP)は、より肯定的な感情と喜びが示された。この分析は、現実の患者経験に関する洞察を提供する。
科学分野:
- 形成外科
- 自然言語処理
- 患者報告アウトカム
背景:
- 自家皮弁は、乳房切除後の再建にますます使用されています。
- 公開フォーラムは、自然言語処理(NLP)分析に適した患者の物語を豊富に提供します。
- RoBERTaモデルは、患者生成テキストデータを分析できます。
研究 の 目的:
- 自家皮弁(深部下腹部穿通枝皮弁(DIEP)、横行腹直筋皮弁(TRAM)、広背筋皮弁(LD))に関する患者の感情と情緒を評価する。
- 異なる皮弁タイプ間での患者報告による経験を比較する。
主な方法:
- DIEP、TRAM、またはLD皮弁を参照するRealSelfからの患者レビューを収集しました。
- 2つのNLPモデル(陽性/陰性の二項感情分類器と、恐怖、悲しみ、怒り、嫌悪、中立、驚き、喜びの感情分類器)を適用しました。
- 各レビューに最もスコアの高い感情をラベル付けしました。
主要な成果:
- 分析対象は212件の投稿(DIEP 153件、TRAM 20件、LD 39件)。DIEP皮弁は最も高い平均陽性感情(0.627)を示したのに対し、TRAM皮弁は最も低い(0.517)でした。喜びは、DIEP(68/153)およびTRAM(7/20)再建で最も頻繁に見られた感情でした。LD皮弁のレビューは「中立」が最も多かった(9/39)。
結論:
- 患者レビューのNLP分析によると、DIEP皮弁が最も多く議論されており、TRAMまたはLDよりも肯定的な感情が大きいことが示唆されています。
- 感情プロファイルは、DIEPでは主に喜びに満ちた物語、LDでは中立、TRAMではそれほど肯定的でない感情を示しています。
- このNLPアプローチは、従来の転帰研究を補完する、大規模な現実世界の患者経験を捉えています。

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.

Nursing Diagnosis

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.

Formulating and Validating Nursing Diagnosis I

A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

Formulating and Validating Nursing Diagnosis II

Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.

Nursing Evaluation
4.1K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.
