Johns Hopkins Medicine researchers successfully tested a “smart agent” system that integrates electronic health records and infusion pumps to help nurses manage the automatic delivery of insulin to critically ill patients, reducing errors and saving time.

Looking for ways to improve this process, researchers at the Johns Hopkins Armstrong Institute for Patient Safety and Quality recently tested a “smart agent” system that integrates electronic health records and infusion pumps to automate insulin dose selection.
