In our colorectal program, metronidazole often wasn’t completed on time, in contrast to cefazolin. A multidisciplinary effort standardized its administration timing, improving infusion completion rates. We evaluated the impact of this intervention on surgical site infections in colorectal surgery.  \n(Received 7 September 2025; accepted 3 December 2025)  \nIntroduction  \nBoth the timing and selection of antimicrobial prophylaxis (AP) reduce the risk of surgical site infections (SSI), but the logistics around varied infusion times are often overlooked.1 National AP guidelines jointly issued in 2013 by the American Society of Health-System Pharmacists (ASHP), the Infectious Diseases Society of America, the Surgical Infection Society, and the Society for Healthcare Epidemiology of America recommend that AP should be infused (both initiated and completed) within a 60 min window before incision.2 However, this recommendation is based primarily on studies focused on first-and second-generation cephalosporins infused via rapid intravenous (IV) push over a number of minutes by an anesthesiologist prior to skin incision. Vancomycin and fluoroquinolones are well known exceptions and are permitted a longer 120 min infusion window, due to rate limitations precluding the ability to completely administer doses in the shorter time frame. Subsequent studies have validated the consequences of failing to adhere to this earlier window for vancomycin, noting increased SSI rates when infusions are initiated too close to the time of incision and describing the significant resource allocation required to coordinate the complex logistics of an operating room setting.3,4 Despite the need for slow IV drip administration and a long half-life with active metabolites promoting adequate tissue concentrations for prolonged periods of time, metronidazole (MTZ) has not been clearly specified in this  \nCorresponding author: Peter Oakes; Email: [poakes16@gmail.com](poakes16@gmail.com)  \nCite this article: Oakes P, Donohue LE, Chiao S, et al.
