Information is power, but sometimes it can be too much of a good thing. Information overload affects workers in every industry – this is particularly true for data-reliant and intensive industries like healthcare. And, it’s not getting any better – by 2020 the healthcare industry alone is estimated to have 25,000 petabytes of data – that’s equivalent to 500 billion four-drawer filing cabinets. With its complexity and breadth, and not least with its impact on our lives, healthcare has to be the poster child for how efficient management of data can improve productivity and help providers make better, more informed decisions.
A first trick, however, is getting at the relevant pieces of information. Today, a lot of manual work goes into accessing and cleaning up data that is siloed and unstructured. Too much information is still on paper, but even where it has been migrated to electronic medical records (EMR), practice management systems, or lab diagnostic systems, much of it is still unstructured. The majority of hospitals are finally implementing EMRs, and many of us are working to provide advanced analytics based on the information going online, but, at a recent Xerox healthcare client council meeting, several CIOs emphasized that there still remains a huge challenge in cleaning, standardizing, and integrating data before it can be used for decision making.
Fortunately, powerful methods are becoming available that can extract relevant events from physician narratives, intelligently aggregate data, customize information for clinicians based on context, and visualize information. For instance, in France, a number of hospitals are testing an emerging application based on Natural Language Processing technology developed at the Xerox Research Centre Europe in Grenoble, France. Researchers designed the solution to help prevent the spread of hospital-acquired infections by finding, extracting, and combining key information in physician narratives distributed in medical records. As another example, our Midas+ Live product accesses and integrates information from diverse hospital systems and puts them on a single dashboard, multiple patients at a time, hugely simplifying a physician’s task to monitor all of his or her patients.
Another challenge is using this abundance of information to make better decisions. Despite selectively whittling down the field to the most pertinent pieces, the amount can still be overwhelming. This is a problem for clinical staff, and we are working on decision support systems for experts, but here I’d like to point to another area, an area where most of the cost in our healthcare system goes: patients with chronic diseases, in particular the elderly and disabled. As relatives and friends, we are increasingly asked to help in the role of caregivers, but the available information does not often help us to make decisions and take actions in that role. In a recent project, we have been looking at the use of social networking to bring in the brain power of volunteers. With this approach, we can harness the expertise and experience of volunteers to personalize the available information to participants’ needs. With a focus on long-term care, and working closely with healthcare providers and government agencies, we’re working to bring this technology to care at home, helping patients to manage their conditions and to closely adhere to care programs in the face of an often bewildering array of medications and care needs.
Another problem Xerox helps partners tackle is the automation of non-core tasks. For example, more than half of a nurse’s work goes toward documentation and task coordination. While important, those don’t add to and often detract from the nurse’s core work. We are developing a solution that uses situational awareness and mobile technology to deliver and update pertinent information, almost as a side effect of the nurse’s work. This technology is still being developed in the lab, but it has the potential to greatly simplify typical workflows that are adjacent to the central task of caring for patients.
Finally, we should remember that optimizing an old process is not always the best solution. We should also rethink healthcare processes that are outdated in the face of new technologies and business models. For example, while we have been automating the healthcare audit business for years, Xerox is also working to provide real-time (pre-pay) fraud detection to payers. There are a number of critical back-office processes that are undergoing similar transformations.
These are just a few ways Xerox is going to task on simplifying healthcare. What are some ways you would suggest?
