Teaching works best when it takes place in the context in which the information will be used. That is one of the fundamental tenants of adult education. Another central principle is that adult learners have other things going on in their lives and cannot spend all their time outside of work still engaged in work related learning activities. An institution that rolls out upgrades to a mission-critical system that is central to the daily care of patients, if they really valued their employees and their patients, would protect time during working hours to allow their employees to learn new features while seeing patients. Or, at the very least, free them from clinical responsibilities for enough time to work with mock patients to learn the new system.
