Important questions include how to identify candidates for an early switch and how to effect the IV-to-PO switch. Releasing IV-to-PO switch guidelines alone is not sufficient. Electronic drug-ordering systems have been introduced during the past years, enabling a central computer to provide a daily list of all patients who are on intravenous antibiotics for more than 48 hours and are therefore potential candidates for an IV-to-PO switch. The consulting infectious diseases physician can review these patients' charts and contact the attending physician to investigate whether the patient can indeed be switched to oral therapy. Electronic drug-ordering systems might be a more convenient way to streamline antibiotic prescribing methods.

In 1999, Teich et al reported on their study of a computer program to facilitate switch therapy. They found that physicians agreed to change (or had just changed) the patient's medication from intravenous to oral in 31.7% of cases. [54]
