BigDataScalability.com – At glance, the term “big data” might sound like a buzzword that is often thrown around. The truth is, that isn’t true today. If anything, big data is very likely to be a part of our future. We can see the trend as more and more organizations across various sectors use big data, including the healthcare sector.

Big data has a long history. Back then, the term refers to a big amount of data. Today, it is much more than that. In this post, we explain what big data is, big data in healthcare, its characteristics, why it is important, why use it, its applications in the healthcare sector, and its benefits.

What Is Big Data?


Before we delve further, let’s get to know what big data is. In general, big data is defined as a large set of complex data, whether structured, semi-structured, or unstructured, that can be used to gain deep insights as well as solve problems that couldn’t be solved using traditional software or analytics.

Usually, data scientists utilize artificial intelligence (AI) -powered analytics to evaluate big data to discover trends and patterns that can provide meaningful insights.

Big data is projected to penetrate deeper and faster into the healthcare sector than in financial services, manufacturing, and media. This is hardly surprising. The healthcare sector is the top private employer in the US. Moreover, the sector’s spending accounts for a fifth of the nation’s GDP.

Globally, the market of healthcare big data is expected to experience an impressive compound annual growth rate of 36% through 2025.

Moreover, due to the rise of investments in electronic health record systems, practice management solutions, and workforce management tools, the global healthcare big data analytics sector is expected to be worth no less than $68 billion by 2024.

What Is Big Data in Healthcare?


The term big data in healthcare can be defined as the use of analytics services, whether prescriptive, predictive, or descriptive, to gain deep insights from healthcare data.

Some others define big data as the vast amount of data that is too large and/or complex for conventional technology to make sense of. The vast amount of data is created by the widespread adoption of the internet and digitization of information, which includes health records.

Previously, the problem has been figuring out how to collect all that data and analyze it to gain actionable insights.

As big data technologies emerge, healthcare organizations are now able to not just consolidate but also analyze such a vast amount of data in order to find trends, better treat patients, as well as make more accurate predictions.

There are three main goals of big data in healthcare:

  • To improve clinical outcomes
  • To boost workforce productivity
  • To improve the healthcare organization’s revenue stream

These goals are achieved by using patient data, leveraging operational data, and using healthcare financial data, respectively.

The “V”s of Big Data in Healthcare Sector


Initially, big data is associated with three key qualities. These key qualities are volume, variety, and velocity. However, it continues to grow and change. As a result, industry experts add another two “V”s, which are value and veracity, to describe its characteristics.

Below we explain each “V” of big data in healthcare.

1. Volume

Volume is the quantity or amount of data. The advance in technology has made it possible for such a remarkable volume of data to flow to and from websites, applications, portals, as well as EHRs.

2. Variety

There is also variety, which encompasses different forms or types of data that we can generate, gather, and analyze.

Structured, semi-structured, or unstructured data can include everything from facts, numbers, and statistics to text, photos, as well as videos.

3. Velocity

The next “V” is velocity, which is the measure of how fast information or data is flowing. It refers to how fast datasets are being generated and processed. The velocity of data affects healthcare organizations and their ability to make accurate and timely decisions.

Thanks to the Internet of Things, cloud computing, and machine learning, data flows in real-time. As a result, data can be available in an instant.

4. Value

Value is the latest “V”s, along with veracity. This term refers to the usefulness of the data and what’s done with said data to make it worth something. It demonstrates the return on investment of the data being generated, collected, or analyzed.

5. Veracity

Lastly, veracity. Veracity is the quality, integrity, or trustworthiness of data that is generated, collected, and analyzed by healthcare organizations.

Note that data is coming in different types from different sources. If we want to draw reliable conclusions from it, we need to make sure of its quality, integrity, and trustworthiness.

Why Is It Important?


There are many reasons why big data is important in healthcare. For example,

Patient care is becoming increasingly complex. Without proper analytics, providing safe and quality patient care is difficult.

Operational inefficiencies, such as records duplication, financial benchmarking difficulties, and missing entitled reimbursements, are caused by inadequate data governance. This is a problem that big data can fix.

Discrepancies between clinical and accounting departments. Unfortunately, this is a common problem for many healthcare organizations. The root causes of these problems are data mismatches and inaccuracies. Again, big data can fix this.

Why Use Big Data?


1. Tracks and prevents care

In the US, the annual cost of delivering healthcare has reached over $3 trillion. This is where big data in healthcare can help. Combined with other health technologies, big data can help healthcare providers track and identify diseases long before they happen. Thus, boosting preventive care.

2. Reduces costs for healthcare providers

The US healthcare costs account for approx. 16.7% of the nation’s GDP. Although the number is hardly surprising, the costs for healthcare providers can be reduced by utilizing big data.

The vast amount of data puts healthcare providers and executives in a better position to make better operational and financial decisions and, at the same time, provide quality and enriched patient care.

For example, using big data, healthcare providers can predict patient booking and minimize financial waste, thereby optimizing staff allocation and thus, reducing costs.

3. Prevents human errors

Human errors are common in healthcare services. It is estimated that human error accounts for approx. 6% of a healthcare provider’s expenses. There are also human errors in prescription dosage, which put a patient’s health and overall well-being at risk. Using big data, these human errors can be prevented.

Big Data Applications in Healthcare


Big data has various applications in any business environment. In healthcare, the applications of big data include

1. Mitigate hospitalization risks

Healthcare organizations can use big data in healthcare to mitigate hospitalization risks. Using big data and healthcare analytics, healthcare organizations are better equipped to track hospitalization risks for patients with chronic diseases.

By analyzing criteria such as the frequency of doctor visits, medication intake, and symptom security, clinics can provide patients with targeted preventive care to reduce hospital admissions.

Using big data, hospitals can predict who might be admitted. This allows hospitals to be prepared well in advance as they can allocate space and necessary resources to prospective patients. 

For example, during the COVID-19 pandemic, doctors are utilizing big data in healthcare to collect data from every part of the nation to pinpoint vulnerable spots that are at the greatest risk.

2. Improve patient outcomes

Another application of big data in healthcare is to improve patient outcomes. Combined with analytic services, big data makes it easy for researchers and clinical practitioners alike to better diagnose and treat diseases.
