Effect of multidisciplinary interventions in perioperative management center on duration of preoperative fasting: A single-center before-and-after study

Abstract

Objectives: Our aims were to clarify the actual situation regarding preoperative fasting and determine whether multidisciplinary interventions in a perioperative management center shorten the duration of preoperative fasting. Methods: The cohort of this before-and-after study comprised patients undergoing elective surgery aged 18 years or older who underwent general anesthesia at one of three stages: after starting a short preoperative fasting protocol (Group A), after the anesthesiologist started explaining the protocol (Group B), and after the start of the perioperative management center (Group C). Instructions on drinking clear fluids were given up to 2 h and 4 h before the start of elective surgery to the first patient on the list (on-time) and to the second and subsequent patients (on-call), respectively. Data were collected retrospectively in Groups A and B and prospectively in Group C. Results: The study cohort comprised 89 patients in Group A (50 on-time, 39 on-call), 108 in Group B (65 on-time, 43 on-call), and 284 in Group C (182 on-time, 102 on-call). The difference between the instructed and last drinking time was significantly shorter in Group C than Group A (30 [10, 140] vs. 30 [10, 60] vs. 20 [0, 50] min, p=0.003). The duration of fasting was significantly shorter in Group C than Group B (243 [150, 395] vs. 213 [151, 323] vs. 180 [146, 280] min, p=0.01). Conclusions: Multidisciplinary interventions at the perioperative management center tended to reduce the duration of fasting, suggesting that this approach may contribute to improved compliance.
