Change in the Perception of Oral Antibiotics Among Medical Students After Participating in a Parenteral-to-Oral Conversion Program for Highly Bioavailable Antibiotics

Abstract

Abstract Background Appropriate conversion of antibiotics from a parenteral to the oral route can lower the risk of catheter-associated infections, reduce medical costs, and shorten hospitalization. This study investigated the effect of a parenteral-to-oral conversion program for highly bioavailable antibiotics on the perceptions of medical students regarding oral antibiotics. Methods In 2021, the parenteral-to-oral conversion program was implemented as one of the activities of an antimicrobial stewardship program at a tertiary-care hospital in South Korea. This program was also implemented for fifth-year medical students in the hospital's infectious diseases department as a core clinical practice course. Medical students reviewed the medical records of patients taking antibiotics with a high oral bioavailability and wrote a recommendation for oral conversion after confirmation by an infectious disease specialist. A survey on the perception of oral antibiotics was administered to medical students before and after clinical practice to evaluate the educational effect of the program. Results A total of 923 cases were reviewed, and more than one-fifth of the antibiotics with a high oral bioavailability were administered parenterally despite their oral conversion (20.6%, 190/923). Of these, 24.2% (46/190) accepted the written proposal within 48 hours, and 43.7% (83/190) declined the proposal. Through this program, students gained a proper perception of oral antibiotics. Conclusions The parenteral-to-oral conversion program demonstrated an acceptance rate of oral antibiotic conversion in the hospital of 24.2% and had significant educational benefits for medical students, giving them the ability to construct an appropriate perception of oral antibiotics.
