Researchers identify ways to improve quality of care measurement from electronic health records

January 15, 2013, Weill Cornell Medical College

Health care providers and hospitals are being offered up to $27 billion in federal financial incentives to use electronic health records (EHRs) in ways that demonstrably improve the quality of care. The incentives are based, in part, on the ability to electronically report clinical quality measures. By 2014, providers nationwide will be expected to document and report care electronically, and by 2015, they will face financial penalties if they don't meaningfully use EHRs.

A new, federally-funded study by Weill Cornell Medical College in the Jan. 15 issue of demonstrates ways in which quality measurement from EHRs—which are primarily designed for documentation of clinical care for individual patients—can be improved. In a large cross-sectional study in New York state, researchers demonstrated that the accuracy of can vary widely. Electronic reporting, although generally accurate, can both underestimate and overestimate quality.

"This study reveals how challenging it is to measure quality in an electronic era. Many measures are accurate, but some need refinement," says the study's senior author, Dr. Rainu Kaushal, director of the Center for Healthcare Informatics Policy, chief of the Division of Quality and and the Frances and John L. Loeb Professor of Medical Informatics at Weill Cornell.

"Getting electronic quality measurement right is critically important to ensure that we are accurately measuring and incentivizing high performance by physicians so that we ultimately deliver the highest possible quality of care. Many efforts to do this are underway across the country," continues Dr. Kaushal, also a professor of pediatrics, medicine, and public at Weill Cornell and a pediatrician at the Komansky Center for Children's Health at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

For this study, Weill Cornell researchers analyzed clinical data from the EHRs of one of the largest community health center networks in New York state. The research team examined the accuracy of electronic reporting for 12 quality measures, 11 of which are included in the federal government's set of measures for incentives. What they found was fairly good consistency for nine measures, but not for the other three.

"The variation in quality measurement that we found in a leading electronic health record system speaks to the need to test and iteratively refine traditional quality measures so that they are suited to the documentation patterns in EHRs," says the study's lead investigator, Dr. Lisa Kern, a general internist and associate director for research at the Center for Healthcare Informatics at Weill Cornell.

The automated reports generally performed well. However, they underestimated the percentage of patients receiving prescriptions for asthma and receiving vaccinations to protect from bacterial pneumonia. A third measure suggested that more patients with diabetes had cholesterol under control than actually did. The automated report said 57 percent of eligible diabetic patients had cholesterol controlled, while a manual check of the charts showed it was actually only 37 percent. Part of the problem is that physicians and nurses filling out the EHRs may be typing in information in a place that is not being captured by quality reporting algorithms.

"EHRs create the opportunity to measure and provide feedback to clinicians regarding quality performance in real time, thereby improving clinical practice," says Dr. Kern, who is also an associate professor of public health and medicine at Weill Cornell.

Dr. Kaushal adds, "EHRs are not just electronic versions of paper records but rather tools that enable transformation in the way care is delivered, documented, measured and improved. The federal meaningful use program will enable the deployment of these promising systems across the country, thereby enabling health care to enter the digital age."
