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...

Causality in Epidemiology

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Models of Health Promotion and Illness Prevention II

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 from...

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Criteria for Causality: Bradford Hill Criteria - II

Criteria for Causality: Bradford Hill Criteria - II

The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

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...

Area of Science:

Medical Informatics
Computational Biology
Epidemiology

Background:

Multimorbidity, the coexistence of multiple diseases in an individual, poses significant challenges in diagnosis, prognosis, and treatment.
Existing definitions of multimorbidity lack formal rigor, hindering the development of advanced clinical decision support systems.
The complex interactions between diseases in multimorbidity require precise modeling for effective patient care.

Purpose of the Study:

To develop a formal framework for rigorously defining and analyzing multimorbidity.
To enable the modeling of various aspects and interactions related to multimorbidity.
To support the creation of personalized electronic clinical guidelines and decision support systems.

Main Methods:

A literature review was conducted to identify existing definitions and concepts of multimorbidity.
Causal Bayesian networks were employed to construct a novel framework for modeling multimorbidity.
The framework was analyzed to assess its capability in representing disease interactions.

Main Results:

The study identified a variety of definitions and concepts surrounding multimorbidity.
A novel framework based on causal Bayesian networks was successfully developed.
The proposed framework demonstrates the ability to model a spectrum of multimorbidity aspects and their interactions.

Conclusions:

The developed causal Bayesian network framework offers a robust foundation for understanding and modeling multimorbidity.
Formalizing multimorbidity aspects is crucial for advancing computerized decision support in healthcare.
This framework can significantly aid in personalizing patient care by accounting for complex disease interactions.
