概括
移植计划 (TxPs) 有时会绕过死者捐赠脏的高级候选人,这种做法被称为"列表潜水". 虽然这减少了一些接受者的等待时间,但它并没有改善整体存活率,并且延长了其他人的等待时间.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 移植手术 移植手术
- 医疗保健服务研究 医疗服务研究
背景情况:
- 器官采购组织 (OPOs) 和移植计划 (TxPs) 在美国管理已故捐赠者的脏分配.
- 国家规则优先考虑候选人,授予更高级别的个人优先拒绝的权利.
- 有时,TxP会移植排名较低的候选人,称为"列表潜水",这种做法对结果的影响未得到充分研究.
研究的目的:
- 调查"列表潜水",特别是"目标安置" (TPs) 对移植后接受者和移植物存活的影响.
- 分析是否使用决策之前或同时与多个高优先级候选人下降改善结果.
- 在评估TP的影响时考虑治疗内源性.
主要方法:
- 对已故捐赠脏使用决策的档案数据的分析.
- 使用基于时间的标准识别"目标安置" (TPs),表示TxP临床判断.
- 在比较结果时,统计方法可以考虑治疗内源性.
主要成果:
- 有针对性的安置 (TPs) 显著减少了接收者的等待时间 (2.20与2.64年相比,p<0.01).
- 对于排名更高,跳过的候选人来说,TP延长了等待时间 (1.64对1.37年,p<0.01).
- 尽管等待时间缩短了,TPs并没有显著改善总接收者或移植的存活率.
结论:
- 有针对性的安置可以缩短部分移植患者的等待时间,但不能提高整体存活率.
- 这种做法延长了被跳过的候选人的等待时间,但没有改善他们的长期生存前景.
- 可能需要进一步的研究来了解TxP临床判断对脏分配的全部含义.

Kidney Structure
75.3K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.

Survival Curves
719
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.

Survival Tree
432
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

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...

Decision Making: P-value Method
7.0K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
