The healthcare sector has long been an early adopter of technological advances. These days, machine learning — a subset of artificial intelligence — plays a key role in many health innovations, including the development of new medical procedures, the handling of patient records and the treatment of chronic diseases.


How Is Machine Learning Used in Healthcare? 

Machine learning is applied in a wide range of healthcare use cases, and much of its promise begins with its ability to handle complex data.

Machine Learning in Healthcare

  • Predicting and treating disease
  • Providing medical imaging and diagnostics
  • Discovering and developing new drugs
  • Organizing medical records

The healthcare industry has been compiling increasingly larger data sets, often organizing this information in electronic health records (EHRs) as unstructured data. With the help of natural language processing, machine learning rearranges this data into more structured sets that healthcare professionals can quickly glean actionable insights from. 

Machine learning and AI have also impacted drug discovery and development for pharmaceutical companies. The technology has already supported central nervous system clinical trials, and drugmakers hope ML will predict the ways patients will respond to various drugs and identify which patients stand the greatest chance of benefiting from the drug.

In addition, telemedicine has reaped the rewards of machine learning developments in healthcare, as some machine learning companies are studying how to organize and deliver patient information to doctors during telemedicine sessions, as well as capture information during virtual visits to streamline workflows.

Benefits of Machine Learning in Healthcare

Machine learning has much to offer to the healthcare industry. Below are just a few of the benefits organizations are realizing by applying machine learning in healthcare. 


Faster Data Collection

Healthcare professionals use wearable technology to compile real-time data, which machine learning can quickly process and learn from. That’s why the U.S. Food and Drug Administration has been working to integrate ML and AI into medical device software


Accelerated Drug Discovery and Development

By combining machine learning and deep learning, researchers develop models to more accurately predict successful drug molecules. This speeds up the drug discovery process. 


Cost-Efficient Processes

Machine learning algorithms can quickly scan EHRs for specific patient data, schedule appointments with patients and automate a range of procedures. Healthcare workers are then empowered to focus their attention on more urgent matters.  


Personalized Treatment

By crunching large volumes of data, machine learning technology can help healthcare professionals generate precise medicine solutions customized to individual characteristics. Machine learning models can also predict how patients react to certain drugs, allowing healthcare workers to proactively address patients’ needs.
