The healthcare industry historically has generated large amounts of data, driven by record keeping, compliance & regulatory requirements, and patient care 1. While most data is stored in hard copy form, the current trend is toward rapid digitization of these large amounts of data. Reports say data from the U.S. healthcare system alone reached, in 2011, 150 exabytes. At this rate of growth, big data for U.S. healthcare will soon reach the zettabyte (1021 gigabytes) scale and, not long after, the yottabyte (1024 gigabytes) 6. Kaiser Permanente, the California-based health network, which has more than 9 million members, is believed to have between 26.5 and 44 petabytes of potentially rich data from EHRs, including images and annotations 6.
Data Privacy and Security
Documented policies, procedures, and clear https://www.mindsetterz.com/why-bajaj-finserv-health-is-best-for-online-doctor-consultation/ guidelines should be developed to manage sensitive patients’ information. Big data analytics is used to provide insights and support for clinical decision-making processes. It is applied to identify and prevent unfair activities within the healthcare system 1, 34. Predictive analytics is used to forecast potential health issues or outcomes based on historical data 3. BDA optimizes query times and ensures accurate emulation of data models to enhance the retrieval of patient information in real-time.

But unlocking its full potential means addressing the underlying infrastructure, integration, and compliance demands with the same level of precision. The datasets supporting the findings of this study are derived from a systematic analysis of 35 peer-reviewed research articles, which were selected through defined inclusion and exclusion criteria. Detailed information about these selected studies has been presented in Table 5 of the manuscript. To search all existing literature published worldwide, a comprehensive search is executed through different steps. The most relevant studies having an alignment with the study’s objectives are selected through rigor methods and eligibility criteria. Different major groups and their sub-groups are developed to show different categories of the datasets extracted through the selected studies in systematic literature reviews 78.
Real World—Big Data Analytics in Healthcare
This structured visual representation clarified the number of records retrieved, screened, excluded, and finally included in the analysis to ensure transparency 75. As already mentioned, in recent years, healthcare management worldwide has been changed from a disease-centered model to a patient-centered model, even in value-based healthcare delivery model 68. In order to meet the requirements of this model and provide effective patient-centered care, it is necessary to manage and analyze healthcare Big Data. Cencora is a pharmaceutical distribution company that develops solutions for both human and animal health. It offers advanced data management solutions like rapid data collection and analysis capabilities to make clinical trials more efficient. The company also aims to improve payer access and practice performance through its data-driven approach.
Data warehousing and cloud storage are heavily used to safely and inexpensively store the expanding volume of electronic patient‐centric data to improve medical outcomes 45. In addition to medical applications, research, instruction, and quality assurance all benefit from having access to stored data. For instance, It is important to capture relevant data from the right sources and using cloud solutions to keep the data safe and secure. Finally, many healthcare organizations have seen discrepancies between clinical and accounting departments due to data mismatches.
- Four interviewees shared that healthcare systems use BD and BDA to respond to regulatory requirements from the federal government, payers, or audit needs, as well as to fulfill executive and business unit requests.
- By analyzing data on supply chain logistics, demand forecasting, and inventory levels, organizations can reduce costs, minimize waste, and ensure the availability of essential medical supplies and equipment.
- IQVIA builds links between analytics, data and technology, so pharmacy leaders can complete faster and more effective clinical research.
- These technologies enhance diagnostic accuracy, automate data interpretation, and support real-time clinical insights.
- It can assist healthcare providers in allocating resources more efficiently and identifying high-risk individuals for targeted interventions.
- Novant Health New Hanover Regional Medical Center, for example, uses a data analytics platform to optimize its blood transfusion processes and evaluate opportunities for improvement and the effectiveness of such interventions.
However, in a short span we have witnessed a spectrum of analytics currently in use that have shown significant https://themors.com/where-europes-startups-are-thriving-in-2025/ impacts on the decision making and performance of healthcare industry. The exponential growth of medical data from various domains has forced computational experts to design innovative strategies to analyze and interpret such enormous amount of data within a given timeframe. The integration of computational systems for signal processing from both research and practicing medical professionals has witnessed growth. Thus, developing a detailed model of a human body by combining physiological data and “-omics” techniques can be the next big target.
Other Big Data in Healthcare Applications
IBM Watson has been used to predict specific types of cancer based on the gene expression profiles obtained from various large data sets providing signs of multiple druggable targets. IBM Watson is also used in drug discovery programs by integrating curated literature and forming network maps to provide a detailed overview of the molecular landscape in a specific disease model. Emerging ML or AI based strategies are helping to refine healthcare industry’s information processing capabilities. For example, natural language processing (NLP) is a rapidly developing area of machine learning that can identify key syntactic structures in free text, help in speech recognition and extract the meaning behind a narrative. NLP tools can help generate new documents, like a clinical visit summary, or to dictate clinical notes. The unique content and complexity of clinical documentation can be challenging for many NLP developers.
What healthcare and medical sectors benefit from using big data in healthcare?
The analysts can concentrate on procedures that owing to the enormous volume of healthcare data and processing capacity, increased in size, speed, and complexity to deal with modern data. Due to the dramatic increase in the volume and complexity of data over the past 10 years, many novel data analysis techniques have been developed 54, 55. Big data is distinguished by its large quantity and complexity and is produced from a wide range of sources, such as EHRs (electronic health records), medical imaging, genetic sequencing, and other sources. The rising popularity of DHTs (digital health technologies) and the need for more evidence‐based healthcare decisions have both contributed to the rapid expansion of large amounts of data in the digital health industry in recent years.
This assessment assists to demonstrate the validity, reliability, and robustness of the existing findings on big data analytics (BDA) in healthcare. To address the potential for bias in our research approach, several measures were taken to ensure objectivity and inclusivity in data collection. Although the universities selected were based on the authors’ affiliations, the primary criterion for literature inclusion was relevance to the study’s objectives. All searches followed a standardized protocol using consistent keywords, Boolean operators, and filters to avoid preference of regional publications. Multiple universities from two culturally and geographically distinct countries (Pakistan and Saudi Arabia) were included to provide broader representation and mitigate regional bias.
