A study in Health Psychology showed that better patient care and cost savings can be achieved by modifying an EMR's electronic order set design. Researchers looked at the differences in the tests ordered by clinicians using opt-in, opt-out and recommended test designs and found that three additional tests were ordered by clinicians when they used the opt-out version. "Essentially we found that including default selections ... increased the quality of lab tests the clinicians ordered," said Victoria Shaffer, an assistant professor of health sciences in the University of Missouri School of Health Professions. "However, there were costs associated with using these approaches."
