Big data is emerging in the hospitals and health industries because systems are collecting large amounts of data on patients every single day. The data comes for a variety of settings — clinical, billing, scheduling and so on. previously, a lot of that data was not leveraged to make patient care and hospital operations better. Recently though, there has been a shift to change that. According to Joel Dudley, MD, director of biomedical informatics for The Mount Sinai Medical Center in New York City, healthcare organizations have come to realize that all of their data can be captured and leveraged as a strategic asset.
Dr. Dudley said, “Big data is not just about storing huge amounts of data. It’s the ability to mine and integrate data, extracting new knowledge from it to inform and change the way providers, even patients, think about healthcare.”
Dr Jain of Anil Jain, MD, CMIO of Explorys, a healthcare analytics company, and former senior executive director of information technology at Cleveland Clinic, says Big data will change how physicians take care of patients at an individual level, fostering more personalized support right at a patient’s bedside.
“The analysis to deal with big data can produce valid and relevant data that is more current, which gives physicians the means and motivation to make the right decisions at the right time,” says Michael Corcoran, senior vice president and chief marketing officer of Information Builders, a business intelligence and software solutions company.
• The federal push for electronic health records has increased the number of hospitals and providers who use them, subsequently increasing the amount of electronic data generated.
• Newer reimbursement models and accountable care organizations need large amounts of information to be analyzed in order to more accurately understand what occurs with patients.
• New technology in general, including devices, implants and mobile applications on smartphones and tablets, has increased the amount of data available to providers.
According to Dr. Robicsek, MD, vice president of clinical and quality informatics at NorthShore University Health System in Evanston, Il, Big data also provides predictive models for the likelihood of readmission within 30-days which is another area NorthShore is targeting with its big data and informatics work.
