Each day, health-care providers are bombarded with electronic notifications in patients' electronic health records, alerting them to potential drug interactions.
Many of these notifications go unread because they are irrelevant, dismissed by the physician out of haste, or common knowledge. Critical alerts that sometimes could mean life or death for a patient then go unnoticed and the opportunity to intervene is missed.
To address this issue, Daniel C. Malone, RPh, PhD, FAMCP, a professor at the University of Arizona College of Pharmacy, has received a five-year, $1.58 million grant to develop algorithms that provide relevant, patient-specific alerts about drug interactions. The project – funded by the Agency for Health Care Research and Quality, part of the U.S. Department of Health and Human Services – also will implement the algorithms in electronic health record systems in more than 50 health-care facilities across the United States.
"Current alerts in electronic health care record systems are simplistic and fail to include specific patient factors, leading to excessive warnings about interactions that are not relevant," Dr. Malone said. "Alert fatigue happens when providers are inundated with potential health notifications and this translates to missing important notifications."
This new project, "Meaningful Drug Interaction Alert," builds upon previously funded research that identified numerous gaps in patient safety related to drug interactions. The development of a drug interaction knowledge database, combined with clinically validated algorithms, is expected to increase the specificity of warnings concerning dangerous drug combinations. In addition, the work will identify and report shared experiences to further refine and validate the underlying algorithms.
The promise of computerized algorithms to improve patient safety has remained largely unfulfilled with respect to drug interaction warnings. Further, health-care facilities need assistance and expertise to implement evidence-based clinical decision support, Dr. Malone said.
Dr. Malone's research team includes Sheila Gephart, RN, PhD, associate professor at the UA College of Nursing, and Vignesh Subbian, PhD, assistant professor at the UA College of Engineering, as well as several internationally renowned experts in the field of drug-drug interactions from other institutions.
"Drug interactions can pose a serious risk to patients when they are not identified and addressed," said UA President Robert C. Robbins, MD. "Dr. Malone's efforts to deploy algorithms, in combination with a drug interaction database, will have a tremendous impact on ensuring that physicians receive the information they need to make the best decisions about their patients' health care. This is a great example of how the UA can be a leader in the Fourth Industrial Revolution, by finding transformative solutions to pressing problems."
