The Health-Care Industry Turns to Big Data

When patients show up at a hospital, something dangerous happens: They’re looked at by humans. Because of the hustle in busy emergency rooms and admission wards, many patients get only a cursory review of their health, according to Nicholas Morrissey, a surgeon at New York-Presbyterian Hospital. Mistakes can lead to complications or missed warning signs and may increase a patient’s chance of winding up back in the hospital. So Morrissey is working with Microsoft to train computers to make the kind of snap judgments about new patients’ risk factors that hurried humans often flub. “We don’t want to take the intuition and clinical decision-making out of the process,” he says. “We want to facilitate it.”

As hospitals digitize patient records and amass huge amounts of data, many are turning to companies such as Microsoft, SAS, Dell, IBM, and Oracle for their data-mining expertise, which can help medical providers perform detective work and improve care. The so-called Big Data business has already permeated other industries and generated more than $30 billion in revenues last year, according to research firm IDC. It’s expected to grow to close to $34 billion this year in part because of increased use in the health-care industry. Crunching numbers is potentially good business for hospitals as well. By making “meaningful use” of computer systems, they’re eligible for millions of dollars in government funding from the Obama administration’s $14.6 billion program launched in 2009 to encourage adoption of electronic medical records.
