まとめ
最適化された患者加温パスの実装により、フランネルブランケットの使用量とコストが削減され、低体温症の発生率を増加させることなく、大幅な環境保護と質の高いケアが実現しました。
科学分野:
- 周術期医学;医療における環境持続可能性;手術における質改善
背景:
- 術中低体温症は、臨床的、財務的、および環境的な課題をもたらします。環境的に好ましい加温法には、再利用可能なブランケットや強制空気加温(FAW)ガーメントの最適化された使用が含まれます。最適化された患者加温パス(OPWP)は、環境データとベストプラクティスを統合することによって開発されました。
研究 の 目的:
- 環境への影響を低減し、患者ケアを改善するための最適化された患者加温パス(OPWP)を開発および評価すること。環境データ、ベストプラクティス、および質改善手法を、持続可能な周術期加温戦略に統合すること。OPWPが環境節約、財務コスト、低体温症率、および患者報告のアウトカムに与える影響を評価すること。
主な方法:
- OPWPは、スコーピングレビュー、環境影響評価、および根本原因分析を通じて開発されました。実装には、術前加温の拡大、FAWガーメントの保存、スタッフ教育、および行動戦略を含む、三次ケア病院での9回のPlan-Do-Study-Act(PDSA)サイクルが含まれました。術前および術後の監査により、環境および財務の節約、低体温症の発生率、および患者報告のアウトカムが評価されました。
主要な成果:
- フランネルブランケットの使用は、実装後、患者あたり6枚から3枚に大幅に減少しました(p<0.01)。能動的加温率は、術前(55%から80%、p=0.04)、および術後(0%から55%、p<0.01)で増加しました。年間節約額は940,339 kgのCO2当量および117,978ドルと推定され、低体温症(18%から15%、p=0.77)に有意な変化はなく、患者報告のアウトカムは良好でした。
結論:
- エビデンスに基づいたOPWPは、環境持続可能性と低炭素の患者ケアを達成しました。実装により、質の高い患者ケアを維持しながら、大幅な環境的および財務的利益が実証されました。このパスは、医療現場における持続可能な周術期加温の実践のためのモデルを提供します。

Nursing Process for Patient and Caregiver Teaching II: Planning and Implementation
2.1K
Planning for learning involves the development of a teaching plan. Teaching plans are similar to nursing care plans—both follow the steps of the nursing process. Planning in the teaching process involves setting goals and outcomes. Here, goals identify what a patient needs to achieve to understand a healthcare topic better, whereas the outcomes are the action to be performed by the patient to achieve the goal within a timeframe. For example, if the goal is to educate the patient about...

C4 Pathway and CAM
49.3K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The Carbon Cycle
44.0K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Nursing Implementation
6.2K
Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
