Evidence-Based Risk Communication in Annals of Internal Medicine

Dr. Daniella Zipkin, an Associate Professor of Medicine at Duke University Medical Center, is one of 14 authors who contributed to “Evidence-Based Risk Communication: A Systematic Review,” published in Annals of Internal Medicine in August 2014.

“Evidence-Based Risk Communication: A Systematic Review” reviewed 84 articles focusing on 91 studies that assessed different methods of communicating risks and benefits to patients regarding their health care options. The goal of the review was to identify the communication methods that maximize patient understanding, which is a component of evidence-based medicine (EBM).

The systematic review concluded that visual aids, such as bar graphs or displays of icons, are capable of increasing patient understanding and satisfaction. Other presentation methods reduced patient understanding, such as “number needed to treat” statistics, which are commonly used in health care to express the average number of people who need to receive treatment in order to prevent an additional negative outcome.

In addition to her published research, Dr. Daniella Zipkin also promotes evidence-based medicine in her work as a member of the Evidence-Based Medicine Task Force within the Society of General Internal Medicine.
