Decision Making: P-value Method01:09

Decision Making: P-value Method

5.2K
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...

Randomized Experiments

6.6K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Decision Making: Traditional Method

3.9K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Clinical Trials: Overview01:11

Clinical Trials: Overview

2.5K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Clinical Trials

6.6K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

SBAR II: Application of SBAR

4.2K
SBAR is an effective communication tool used by healthcare professionals to communicate patient information accurately. SBAR stands for Situation, Background, Assessment, and Recommendation. For a better understanding, an example is given below.
SBAR Report from a Nurse to a Health Care Provider
S: "Hello, Dr. Smith. This is Jane, RN, from the Med Surg unit. I am calling to tell you about Ms. White in Room 210, who is experiencing increased pain and redness at her incision site. Her recent...

科学领域:

  • 医学伦理 医学伦理
  • 以患者为中心的护理
  • 临床决策 - 临床决策

背景情况:

  • 共享决策对患者代码状态偏好的影响尚不清楚.
  • 现有的护理模式可能无法充分支持患者对复苏的知情选择.
  • 评估新的方法对于加强终身护理讨论至关重要.

研究的目的:

  • 为了比较一个共享的决策方法与通常的护理患者代码状态讨论.
  • 评估共享决策对患者做不复苏 (DNR) 偏好的影响.
  • 评估对决策质量的影响,特别是决策不确定性.

主要方法:

  • 一个实用的集群随机对照试验,涉及206名住院人员和2663名医疗患者,遍及瑞士6家教学医院.
  • 干预组接受了培训,检查清单和决策辅助,以便共享决策;对照组接受了通常的照顾.
  • 主要终点:患者选择DNR状态. 二级终点:通过决策冲突量表来确定决策不确定性.

主要成果:

  • 分享决策组的患者更有可能选择DNR状态 (50.0%对37.2%;调整后的RR,1.37).
  • 干预组报告的决策不确定性显著降低 (决策冲突量表上14.4比21.8分).
  • 该方法在统计学上显著地影响了代码状态偏好和决策质量.

结论:

  • 共享决策,包括讨论预期结果,显著影响医疗患者的代码状态偏好.
  • 这种方法导致人们更倾向于做不复苏的状态,并与减少决策不确定性有关.
  • 这些发现支持将结构化共享决策纳入终身护理计划.
