The Big Benefits and Challenges of Big Data in Healthcare

December 3, 2020 - 7 minutes read

New advancements in data science and big data may be just what the doctor ordered for the healthcare industry. According to Global Market Insights, the market share of healthcare analytics is predicted to grow by 12.6% by 2025. Increased access to medical databases has opened up more possibilities for predictive analytics, focusing on reducing preventable diseases, and revolutionizing the efficiency and personalization of patient care.

But while big data brings a variety of benefits to healthcare, it also comes with a few unique challenges. Let’s delve into both sides of this equation.

The Monumental Benefits

Medical data is rich with historical information, and examining a large number of medical records can yield obvious patterns into diseases, treatments, and patient health. Using big data and data science, medical developers can help healthcare providers turn data into actionable insights. These insights can be vital to patients and their lives, and stakeholders like insurance companies, pharmaceutical enterprises, and healthcare providers benefit too.

Some major benefits include creating comprehensive patient profiles, enhancing the patient experience which leads to higher patient satisfaction, and optimizing hospital administrative workflows. Other benefits include making the healthcare industry more cost-effective, improving medical procedures by increasing efficiency, and finding patterns in treatment outcomes almost instantly. Patients can expect a more personalized approach to care, more accessible electronic health records, and higher levels of engagement from their providers.

For the industry overall, there will be a major lift in productivity, efficiency, and quality of service. And over time, the cost of analytics and data servers is expected to decrease while speed and capacity increase. Data science in healthcare creates a holistic profile of the patient in real-time while processing new information like diagnoses, lab results, medications, demographics, and procedures.

More Applications

Several enterprises, large and small, like Cerner Corporation, IBM, San Francisco-based Oracle, and MedeAnalytics, have developed expertise in medical analysis both inside and outside of the clinical environment. These market leaders are pushing the boundaries of data science in healthcare while making the technology more accessible to smaller hospitals and those in rural areas.

Among the myriad applications of data science in healthcare and medicine, we’ve outlined a few key areas below.


Genomics is an indispensable part of medicine and healthcare, and data processing tools are helping sort out what’s most impactful from the rest. Using historical data, analysts can interpret and understand data to develop recommendations for sequencing experiments.

Predictive Analytics

The medical and healthcare industries can extract a lot of valuable insights from data, like predicting trends and behavior patterns to improve the patient experience and calculate the probability of medical outcomes based on past data and statistical analysis.

Medical Imaging

Although AI is doing a great job of helping radiologists find minute details in medical images, big data can help interpret X-rays, MRIs, and mammographies to find tumors, see patterns in the data, look for anomalies, and recommend next steps.

Monitor Patient Health

Healthcare providers can monitor their patients’ health by continuously storing and analyzing medical information from patients. Providers can also use analytics to monitor patient vitals like body temperature, heart rate, and blood pressure — all in real-time.

Provide Virtual Help

Patients can find virtual care with comprehensive platforms that provide secure video conferencing, an easy way to view their medical history, and a way to get back in touch with the doctor. There are also platforms that allow patients to enter their symptoms into a search bar to find possible diseases and causes of illness. The platform will subsequently offer recommendations on the next steps, providers nearby, and possible solutions.

Launch New Drugs

Using data science, pharmaceutical companies are predicting financials and the potential impact of a new drug by analyzing data from operational pipelines starting from the manufacturer and all the way down to the consumer.

Track and Manage Health Conditions

Providers can use data science to track potential cases that their patient is prone to. For example, patients with diabetes can benefit from constant tracking meals, blood glucose levels, and physical activity zones.

Overcoming Challenges

Although the potential and promise of data analytics in healthcare seems endless, there are some challenges that have been uncovered. For example, there is always the lingering risk of cybersecurity attacks. Because healthcare data is private and requires the highest level of discretion, it’s imperative to layer robust security protocols on top of any analytics application.

Other challenges in analyzing and processing big data include a shortage of IT professionals with relevant experience, ensuring data safety, and issues with data integrity. There are also issues surrounding the lack of regulations, best practices, and unified procedures.

Access to Data and Technology

Giving hospitals, medical providers, and stakeholders in the healthcare industry access to technology for analyzing vast amounts of data has already made a positive impact on patients and providers. It has also improved the quality of care by allowing us to predict trends, prevent diseases, monitor symptoms, manage health conditions, find better pharmaceuticals, and more accurately calculate dosages.

Using big data and data science, healthcare is poised to explode in growth and patient satisfaction. What will we use data analytics for next? As always, let us know your thoughts in the comments below!
