Abstract
: We evaluated pre- and post implementation of Virtuo on outcome in patients with gram-negative bacteremia using a quasiexperimental time-in-motion design.
: Becton Dickinson BACTEC™ 9000 series (Bactec) (2018) and Virtuo system (2020) were utilized in a decentralized and centralized process, respectively. Data collected in August-December in 2018 and 2020 were analyzed with SPSS (ver 28).
: For 185 patients in each time period, patient age, gender, length of hospitalization were not different. However, blood culture (BC) volume was significantly lower in 2020 (7.1 mL ± 2.6) compared to 2018 (8.9 mL ± 1.9). Time from BC draw and time from pathogen identification (ID) to treatment change were both significantly faster in 2020 (52.9 ± 38.3 h; 15.1 ± 27.4 h), compared to 2018 (65.0 ± 46.3 h; 23.8 ± 33.8), respectively.
: Replacement of decentralized Bactec with centralized Virtuo, resulted in significant improvement in management of patients gram-negative bacteremia.
