The healthcare industry is complex, highly regulated, composed of legacy systems, and ripe for change and opportunity. It is a large ecosystem that encompasses many different types of organizations, including:
• Government regulatory agencies
• Health information providers
• Healthcare payers
• Healthcare providers
• Independent research and testing laboratories
• Medical device manufacturers
• Pharmaceutical companies
The common denominator among all these players is that they create and manage a huge amount of data. Typically this data is managed in silos without any context or common metadata. However, this is no longer good enough. To drive better decisions, it is critical that an analyst be able to bring together data from across these areas. To make things even more complicated, data comes in many different forms, including structured data from medical tests and demographics and unstructured data from doctors’ notes, CT scans, and MRIs.
Why do we need to take a holistic view of data across these silos? It is clear that there is much that we can learn from unlocking the knowledge from the massive amount of healthcare data that already exists. One of the great challenges for the healthcare industry is the need to understand the patterns and anomalies hidden in data to improve treatments and discover new drugs. In addition, we need better insights to quickly understand new viruses and epidemics that may suddenly threaten millions.
Using a Cognitive Approach to Interpret and Learn from Data
Gaining a true understanding of treatment options requires bringing together data from multiple ecosystems in a consistent and holistic way. Cognitive systems can capture and integrate both unstructured data from medical journals and images with structured data systems from databases. It does little good to analyze these data elements in isolation. The value of a cognitive computing approach is that these data elements can be brought together into a corpus that addresses a specific problem. A corpus is the knowledge base of ingested data and is used to manage codified knowledge from a variety of related sources. Therefore the corpus is optimized to determine patterns and relationships between data elements and data sources. By applying this approach to healthcare, it is possible to gain insights and correlations that might not be apparent.
Applying Cognitive Computing in the Real World
It is often difficult for doctors to diagnose diseases when they lack experience or encounter symptoms they haven’t seen before. The solution to a patient’s problem is not always obvious, even after a battery of tests. Doctors are most efficient and successful when they already have the experience and knowledge to make sense out of a complex situation. What happens when an individual doctor lacks experience? The typical doctor with only a few years of clinical experience may come upon a patient with unfamiliar symptoms. The doctor may try to diagnose the issue based on limited experience. However, a majority of doctors will take the time to cull through recently published medical journals to find mentions of the symptoms. In other cases, that doctor will contact a specialist who may have seen these same symptoms hundreds if not thousands of times. This approach leaves too much to chance.
Hospitals and healthcare organizations are creating models based on data to capture the experience and expertise of seasoned physicians. For example, what does the data indicate about hospital readmissions or what infections are most common in a certain demographic over the last year? What are the patterns from hundreds of thousands of hospital records? What is the most up-to-date research from medical journals telling the hospital about new treatments and new threats?
A cognitive application built on a corpus of data that is constantly refreshed and updated with new information has the potential to provide a sophisticated tool to help professionals gain insights into data that would be out of their reach. Physicians can’t possibly read and analyze all of the new medical research that is published daily. A cognitive system that can both ingest a huge amount of unstructured data and make sense of the patterns and relationships can become an important tool in the diagnosis and management of illnesses.
What’s Next?
The ability to capture all of the available information and create a system that continues to morph and change is at the heart of a cognitive environment. Over the coming decade, the field of cognitive computing applied to healthcare will expand rapidly. Cognitive analytics will provide insights into new treatments and diagnoses of diseases. It will provide new approaches to help transfer the knowledge from the most experienced physicians to new doctors in record time. Combining the ability to train data based on human experiences with the ability to understand context and patterns will revolutionize medicine.
