Several challenges--including a culture still reliant on paper records--stand in the way of big data's use in the public health sector, according to an article published in Government Health IT. Chris Belmont, CIO of New Orleans-based Ochsner Health System, told Government Health IT that such a culture--a "retrospective and reactive" one in his eyes--clogs fluency in the healthcare industry, as a whole. "It's really still a paper-based system," he said. Belmont also pointed to mobilization of data across systems as a challenge for his organization. "We have a total of about 225 information systems that we support here at Ochsner," he said. "And all of these systems, more or less, keep their data in islands." Article
