医疗保健服务研究医疗服务研究
生物统计学生物统计学
卫生经济学卫生经济学

背景情况:

人们对医疗保健提供者数量与护理质量之间的关系非常感兴趣.
现有的研究往往缺乏统一的统计框架,并采用低于最佳的建模技术.
了解体积与结果的关联对于改善医疗保健和患者安全至关重要.

研究的目的:

提出一个灵活的,添加混合模型来分析医疗保健中的体积-结果关联.
开发一个统计框架,考虑患者的特征和提供者特定的影响.
为了能够直接比较体积效应和体积独立的提供者效应,以了解护理质量的变化.

主要方法:

采用了层次增剂混合模型,将提供者体积视为连续,平稳的函数.
纳入患者特异性风险因素,以适应不同的病例组合.
采用随机拦截来进行供应商级集群,以估计平滑的体积效应和体积独立的供应商效应.
使用因果定向环形图 (DAG) 来解释体积-结果效应的因果条件.

主要成果:

拟议的模型成功地提取了平滑的体积效应和体积独立的提供者效应.
该框架允许直接比较这两种效应的幅度,提供对护理质量变化的洞察力.
估计数量的信心集是通过联合估计提供的.

Models of Health Promotion and Illness Prevention I

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Methods of Documentation VI: Case Management Model

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Guidelines for Writing Outcome

Guidelines for Writing Outcome

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...

Concepts of Health and Illness

Concepts of Health and Illness

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...
