Health IT Aspires to Reduce Readmissions

Efforts to keep recently discharged patients from returning for another hospital stay could mean better health for patients and save hospitals millions of dollars. Hospital readmission is a nationwide problem as one out of every five Medicare patients return to the hospital within 30 days of their release. With the passage of Health Care Reform, hospitals with excessive readmission rates will soon be subject to severe financial penalties.

A project being worked on by researchers at the North Carolina Translational and Clinical Sciences Institute (NC TraCS) may be able to reduce those rates by giving primary care doctors the information they need to effectively care for their patients once they go home. The venture makes discharge summaries available electronically and uses health informatics to mine the summaries for important information regarding follow-up.

“Let’s imagine someone gets admitted to the hospital with a really bad urinary tract infection,” explains Carlton Moore, MD, a clinical associate professor of medicine at the University of North Carolina (UNC) in Chapel Hill, N.C., and a leader of the project. “That patient would get a chest x-ray as part of their admission, and if the x-ray were to show an abnormality, the hospital physician would typically not make them stick around to get it worked up, but would allow the result to be followed as an outpatient.”

“The way the current health care system is structured, the burden lies with the patients or physicians to remember to follow up. Unfortunately, human beings are fallible and things can fall through the cracks,” continued Dr. Moore. “Now the trend is toward developing systems that absorb human fallibility so that when doctors or patients forget to follow up there is something built into the system that alerts them to follow up on an abnormal test result or doctor’s appointment.”

With a $500,000 informatics grant from the Duke Endowment, Dr. Moore and Don Spencer, MD, vice president of ambulatory care for the UNC Health Care System, led a team that transferred complete discharge information for UNC patients to Community Care of North Carolina (CCNC). Dr. Moore says UNC is the first hospital in the state to put this information into CCNC’s provider portal (an electronic system that helps case managers ensure that patients are taking their medications) and following up with primary care doctors after their hospitalizations.

“The bottom line is the case managers to date have not had access to the discharge summaries to know how to best take care of their patients,” said Brent Lamm, director of information technology at NC TraCS. “Even then, these discharge summaries can be pages long, making it challenging for the case workers to read in their entirety and then glean what is relevant. So we are using informatics technology to distill down a complex discharge summary into actionable information the case managers can efficiently use in their work.”

The researchers are employing an informatics technique known as natural language processing to analyze the discharge summaries, pull out relevant textual information and flag abnormal findings for follow-up. Armed with a NC TraCS $50,000 pilot award, Dr. Moore and his colleagues will use their approach to identify abnormal results from a test set of computerized axial tomography (CAT) scans, mammography and Pap smears before expanding to other types of visual data.

“I am looking at it more from a quality of care perspective, just to make sure that these abnormal results actually get followed up on,” said Dr. Moore. “The vast majority of the time these masses are benign, but every once in a while they are malignant and warrant surgery or chemotherapy. We don’t want to miss those.”
