Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Inductive Reasoning

Inductive Reasoning

Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. It is uncertain and operates in degrees to which the conclusions are credible. As such, inductive arguments can be weak or strong, rather than valid or invalid, and conclusions can be used to formulate testable, falsifiable hypotheses.
Inductive reasoning is common in descriptive science. A life scientist makes observations and records them. This data can be qualitative or...

Reasoning

Reasoning

Reasoning is the action of thinking about something in a logical, sensible way. It is integral to problem-solving, decision-making, and critical thinking. Reasoning can be inductive or deductive. Reasoning involves transforming information into conclusions, which is essential for problem-solving, decision-making, and critical thinking.
Inductive reasoning involves deriving generalizations from specific observations. This type of reasoning helps form beliefs about the world. For example,...

Deductive Reasoning

Deductive Reasoning

Deductive reasoning, or deduction, is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning, which means that it uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid.
For example, a researcher can deduce specific predictions...

Area of Science:

Bioinformatics
Computational Biology
Ontology Engineering

Background:

Biomedical ontologies are crucial for data annotation and integration.
Insufficient formalization of relations limits automated reasoning in many ontologies.
This hinders large-scale data integration and knowledge discovery.

Purpose of the Study:

To enhance automated reasoning over biomedical ontologies.
To improve data integration and knowledge discovery using formal knowledge representations.
To identify and resolve contradictions within biomedical ontologies.

Main Methods:

Aligning terms in biomedical ontologies with foundational classes in a top-level ontology.
Formalizing composite relations as class expressions for improved semantics.
Semi-automated repair of identified contradictions.

Main Results:

Identified several thousand contradictory class definitions in biomedical ontologies.
Demonstrated expressive queries over interoperable ontologies.
Developed a method to improve automated reasoning capabilities.

Conclusions:

The developed method significantly enhances automated reasoning over biomedical ontologies.
This work provides a cornerstone for robust data integration and knowledge discovery.
The approach facilitates more reliable inference from formal knowledge representations.
