まとめ
年間外傷件数(ATV)ではなく、処置件数(PV)の方が外傷センターにおける患者の予後をより良く予測する。PVが高いほど、死亡率と合併症率が低いことと関連しており、外傷ケアの地域化を改善するためにPVを統合することが示唆される。
科学分野:
- 外傷外科; ヘルスケアの質改善; 外科的予後研究
背景:
- 米国外科学会(ACS)は現在、年間外傷件数(ATV)のみを使用して外傷センター(TC)を検証している。本研究では、PVがTCのパフォーマンスと患者の予後を評価するためのより優れた指標を提供するかどうかを調査する。
研究 の 目的:
- 年間外傷件数(ATV)または処置件数(PV)で層別化されたACSレベルI外傷センターにおける患者の予後を比較すること。PVがATVよりも院内死亡率および主要合併症のより良い予測因子であるかどうかを判断すること。
主な方法:
- ACS-TQIPデータベースを使用して、2017年から2021年までの182のACSレベルI TCの2,218,425人の患者を対象とした後向き分析。センターは、ATVとPVの両方に基づいて、低、中、高の3分の1に分類された。PVには、緊急開腹術、開胸術、頭蓋切開術/開頭術、血管塞栓術、血管修復が含まれた。多変量回帰分析を使用して、交絡因子を調整した後、ボリューム指標と予後の間の独立した関連を評価した。
主要な成果:
- 高処置件数(PV)のTCは、低および中PV TCと比較して、死亡率(3.7%)および主要合併症率(3.1%)が有意に低かった。逆に、高年間外傷件数(ATV)のTCは死亡率(4.5%)が高く、中ATV TCは主要合併症率(5.3%)が最も高かった。高PVは、交絡因子を調整した後、死亡率および主要合併症のオッズ減少と独立して関連していた。
結論:
- 処置件数(PV)は、年間外傷件数(ATV)と比較して、外傷センターにおける患者の予後改善のより優れた予測因子である。PVを外傷センターの検証基準に統合することで、外傷ケアの地域化を強化し、リソースを傷害特異的な患者のニーズに合わせることができる。

Catalytically Perfect Enzymes
4.9K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

Predicting Reaction Outcomes
10.3K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Impact of Groups on Groups

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Impact

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
