Ontology and Taxonomy in the Healthcare Industry: Improving Patient Care

As we step into the second decade of the 21st century, it becomes increasingly evident that the healthcare industry has become the frontrunner when it comes to technological advancements - from the development of state-of-the-art medical equipment to cloud computing infrastructure that aids physicians in providing prompt and timely medical attention.

However, with so many advancements, the healthcare industry is still grappling with a significant problem - the proper management of healthcare data. In most cases, healthcare data is burdened by a lack of easy categorization, making it harder to retrieve useful insights. That's where ontology and taxonomy come into the picture.

Ontology and taxonomy have been a significant part of computer science in recent years, aiding researchers in organizing digital information. And now, the healthcare industry has begun to weave these practices into their daily routines with the aim of providing better patient care. In this post, we'll explore the significance of ontology and taxonomy in the healthcare industry and how they are improving patient care.

Overview of Ontology and Taxonomy

To start, let's define ontology and taxonomy. In simple terms, Ontology is the study of how things are categorized and administered, while Taxonomy is the classification of things based on predetermined criteria.

In the context of the healthcare industry, ontology is the practice of defining specific medical concepts and identifying their relationships. Taxonomy, on the other hand, categorizes the medical concepts into various kinds of relationships.

Ontology and taxonomy, when weaved into the healthcare data's fabric, can aid physicians in easily identifying and using data patterns to develop more effective treatment plans. In a nutshell, ontology and taxonomy facilitate healthcare professionals' decision-making process, enabling them to provide better and more targeted patient care.

Current problems in healthcare data management

Before we jump into the significance of ontology and taxonomy in the healthcare industry, it's crucial to first understand the current difficulties the industry faces when it comes to handling healthcare data.

One of the most significant problems in healthcare data management is the sheer amount of unstructured data available. Medical records, lab results, and imaging studies are all stored in different formats, making it almost impossible to collate and standardize.

In addition, there are various industry-specific terminologies and codes that are unique to different healthcare providers, making it difficult to share data among healthcare providers - this is where the need for semantic interoperability comes into play.

Semantic interoperability refers to the ability of disparate systems to meaningfully communicate with each other. It is essential in the healthcare industry as it facilitates the seamless exchange of relevant patient data between healthcare providers, especially in cases where a patient is being treated by different healthcare providers.

Furthermore, physicians need to be able to use the data they have to pinpoint the most effective treatment plan for a patient. However, the current approach to data management in healthcare is hindering this process.

Enter ontology and taxonomy.

Role of Ontology and Taxonomy in Healthcare

Ontology and taxonomy have become integral to the healthcare industry's efforts to improve patient care. Here are some ways they are being used:

Standardization of Medical Terminologies

There are different medical terminologies currently used in the world. This diversity raises the need for standardization, which is where ontology and taxonomy come in. Ontologies are semantic structures that can enable the standardization of medical terms and codes.

When medical terminologies are standardized and incorporated into the ontology of electronic health records (EHR), physicians can easily share data and retrieve relevant information. This can streamline medical procedures and improve patient safety.

Improved Diagnosis and Treatment Planning

In order to develop effective treatment plans, physicians rely on information and data retrieved from different sources. If the data is unstructured or does not relate directly to the patient's symptoms, it becomes difficult to develop an accurate diagnosis and treatment plan.

By using ontology and taxonomy, physicians can use data patterns to derive more insightful diagnoses and create more effective treatment plans. This not only ensures patients receive better care but can also lead to reduced healthcare expenses.

Personalized Medicine

In healthcare, the one-size-fits-all approach does not work. Every patient needs to be treated according to their unique symptoms and medical history. This is where personalized medicine comes in.

Personalized medicine refers to the use of a patient's unique genetic makeup and medical history to tailor treatment plans. By using ontology and taxonomy, physicians can use medical data to understand the patient's genetic variation and tailor treatment plans to their unique biological profile. This results in higher chances of successful treatment, improved clinical outcomes, and enhanced patient satisfaction.

Advanced Research and Development

Ontology and taxonomy can aid the healthcare industry in advanced research and development. By organizing healthcare data into structured and standardized formats, researchers can easily identify trends, draw accurate conclusions, and develop targeted treatments for diseases.

This promotes data-sharing, where the researcher can share data more readily with other researchers and scientists, which can ultimately lead to the discovery of new treatment options and disease-identification tools.


In conclusion, ontology and taxonomy have become significant in the healthcare industry's efforts to improve patient care. The standardization of medical terminology, improved diagnosis and treatment planning, personalized medicine, and advanced research and development are some key areas where ontology and taxonomy have contributed to better healthcare practices.

As the healthcare industry evolves, there will be a greater need to standardize and organize medical data in a more structured, semantic format. With ontology and taxonomy, the industry is better equipped to manage the vast amount of healthcare data available, leading to improved patient care.

The adoption of ontology and taxonomy practices in healthcare data management will prove to be a game-changer for healthcare providers and patients alike. We, as a society, can only look forward to increased efficiency, improved patient safety and higher clinical outcomes in the coming years.
