Abstract

Despite widespread support for reduced fasting protocols prior to anesthesia, the traditional "fast from midnight" (FFMN) remains widely employed. This study implemented a pilot preoperative fasting reduction program for patients booked for acute surgery in the Department of General Surgery at a busy metropolitan tertiary hospital, including use of an electronic health record (EHR)-based solution, aiming to measure effect on fasting times and use of intravenous fluid (IVF). A pilot program was implemented in August 2021 in the Emergency General Surgery (EGS) unit at the Royal Melbourne Hospital, Australia. This included a new smart phrase within the EHR (EU2WU6: Eat until 2, drink water until 6) and an education campaign. Adult patients who underwent preoperative fasting between September 1 and December 31, 2021, were screened. Uptake of the protocol was recorded. Further, total fasting times (TFT) and IVF use were recorded. Potential impact with varying levels of protocol uptake was modeled. Uptake of EU2WU6 increased from 0% to 80%. TFT and total time on IVF (TT-IVF) were lower using EU2WU6 (TFT 7 hours vs. 13 hours, p < 0.001; TT-IVF 3 hours vs. 8 hours, p < 0.001). Proportion of patients requiring fluid overnight when using EU2WU6 was lower (18/45 vs. 34/50, p = 0.0062). Hospitalwide yearly savings, with 100% application of EU2WU6, were projected at 2,050 bags of IVF (at a cost savings of A$2,296), 10,251 minutes for physicians, and 20,502 minutes for nurses. The pilot preoperative fasting reduction program successfully reduced disparity between evidence and clinical practice.
