    Being conscious of health has become a notable part of human life. To achieve better health, we are willing to invest in tools and advanced technologies.

    People regularly see doctors or their respective physicians for follow-up and check-ups. Since the data concerns human lives, this allowed the healthcare industry to hold accurate patient records. Carefully documenting, storing, and analyzing the data became important in the healthcare industry; it is now experiencing a major shift since big data analytics have influenced the industry.

    As everyone knows, healthcare is the most complex sector that has to undergo rapid changes to ensure advanced facilities and diagnosing techniques. Hence there is no surprise of the arrival of big data in healthcare. It helps healthcare sectors to store a huge amount of patient data to maintain an overall patient record.

    Big healthcare data refers to the plentiful health data gathered from various sources, including electronic health records (EHRs), medical imaging, genetic sequencing, payer records, pharmacy studies, wearable, and, to name a few, medical devices.

    It is distinct from conventional electronic medical and human health data used for decision-making by three characteristics:

    • It is accessible in huge volumes;
    • It travels at high velocity and covers the health industry’s massive digital universe,
    • And since it comes from multiple sources, composition and design are highly variable.

    Big Data in Healthcare

    Track one’s Health

    Healthcare practitioners can now monitor the critical factors and statistics of various patients and service users through Big Data and Analytics in the healthcare industry.

    This is groundbreaking in terms of how effective healthcare can be, as it facilitates patient management in a way that has never been done before. By health monitoring, the heart rate, sleep, and exercise of a patient can be tracked. Recent medical advances can also go one step further and monitor the pulse, blood pressure, and glucose levels of a patient.

    It allows for a healthcare industry that is more pro-active and forward-thinking since health practitioners may restrict those who spend time in the hospital by tracking and intervening until there is a significant health issue.


    Healthcare is expensive.

    Many hospitals and healthcare organizations struggle to meet the requirements to ensure the patient’s quality of treatment. The arrival of big data would enable to reduce costs since it has predictive analysis. The predictive analysis would assist in predicting admission rates and staff administration.

    The use of health tracking and monitoring the hospitals and healthcare centers can detect various chronic illnesses from the beginning. Hence, it can reduce the risk and the money that has to be spent on the recovery.

    Limiting the Errors

    It has been noted several times that clinicians appear to either administer an incorrect drug or wrongly dispatch a different medication. This kind of error can be minimized in general because it is possible to use Big Data to evaluate user data and the prescribed medication.

    It can corroborate the data and flag potential beyond the prescription venue to minimize errors and save lives. For physicians who tend to many patients in a day, such tools can be a great tool.

    A Better Transformation in Healthcare

    Big data can be a great advantage for development in science and technology, aside from the present scenario. Artificial Intelligence, such as IBM’s Watson, can be used for Healthcare to browse several data in seconds to find remedies for different diseases.

    Such development is already underway and will continue to expand with the amount of research that Big Data has collected. Not only will it be able to provide accurate solutions, but it will also be able to provide personalized solutions for specific issues.

    The availability of predictive analysis can benefit patients traveling to a specific geographical location by observing similar patients in that area.

    Real-time Care to the Patients

    The healthcare facilities are now ensuring real-time care and attention to the patients since demand proliferates each day.

    Nowadays, big data is a helping hand for the hospital authorities to collect the real-time symptoms and changes vital for the diagnosis and medications. Wearable sensors and devices would capture each change happening in the patient’s body to make healthcare more convincing and compelling.

    Assistance for the Critical Patients

    High-risk patients will now be better helped and more closely tracked by digitizing hospital and patient data.

    For instance, if a patient has been regularly admitted to the hospital, data can be obtained to establish trends in their health conditions and be identified for any chronic problems. This knowledge advancement will offer patients quality services and minimize repeated hospital visits. In order to be intact with the modern-day healthcare technology, hospitals need to create an immense effect on critical care patients.

    Why Big Data has a significant role in healthcare?

    In healthcare, the use of big data is beyond our expectations. 

    In a short time, technology has altered the definition of the Healthcare Industry. Finding out the future illness, maintaining solid patient records, and helping the medications; the big data has limited the health centers’ workforce.

    For doctors and clinics, collecting error-free data from patients is no longer a challenge. Such data will ensure patients are assessed in real-time without taking too much time and resources. Big data reduces the risk of treating patients in critical condition. Effective use of big data can bring out a lot more in healthcare; it can facilitate precision in the medicines and tests.
