Hospitals like Penn Medicine in Philadelphia are using mobile devices to broaden access to electronic health records. “We have been able to provide our clinical community with critical patient data via a variety of media to enhance patient care and smooth transitions,” says Michael Restuccia, vice president and chief information officer at Penn. The proliferation of confidential medical information on patients’ and clinicians’ mobile devices has led to an increased focus on maintaining the security of the records on those devices. The issue is likely to get bigger as hospitals engage patients in their own care with mobile access to patient portals. Already, 89 percent of Most Wired health systems and 79 percent of all surveyed hospitals offer portal access through a mobile application, according to the 2015 Most Wired Survey.
