まとめ
医者は陰道出産か帝王切開のどちらかを選択する際に,決定のショートカット,またはヒューリスティックを使用することができます. この研究では 患者さんの以前の合併症が 医者に不適切な影響を及ぼすことが分かりました
科学分野:
- 産婦人科
- 医療 に 関する 意思決定
- 医療サービス研究
背景:
- 産出に関する臨床的決定は リスクが高いもので しばしば プレッシャーや不確実性のもとに行われます
- 意思決定理論は,このような環境でユーリスティクス (簡略化されたルール) を採用することを示唆しています.
研究 の 目的:
- 医師の出産方法の決定 (陰道 vs 帝王切開) が特定のヒューリスティックによって影響されているかどうかを調査する.
- 以前の患者のアウトカムが,その後の出産方法の選択に影響するかどうかを判断する.
主な方法:
- 8万6千人の出産の 電子医療記録の分析
- 患者の以前の合併症と,その後の出産方法の選択との関係を統計的に調べる.
主要な成果:
- 医師は,従来の患者が合併症を患った場合,その後の患者に投与方法を変更する傾向がありました.
- このモードスイッチングは,現在の患者の特定の医学的な指示に関係なく起こりました.
- このヒューリスティックは 患者にとって 最適でない健康的な結果をもたらすという証拠があります
結論:
- 医師は,患者の最近の病歴に影響を受け,出産モードの意思決定にヒューリスティックを使用することができます.
- この意思決定パターンは,不適切な配達方式の選択につながり,患者の健康に悪影響を及ぼします.
- 高圧の臨床環境でヒューリスティックバイアスを緩和するには,さらなる研究が必要です.

Heuristics
174
Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

The Availability Heuristic
6.6K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Reason and Intuition
7.1K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Documentation of Nursing Diagnosis
1.4K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
