Clostridioides difficile infection (CDI) poses significant challenges due to its varied clinical presentations and shifting epidemiology. The 2021 IDSA guidelines recommend a two-step testing approach—such as nucleic acid amplification tests (NAAT) followed by toxin enzyme immunoassays (EIA)—to enhance accuracy and minimize overdiagnosis. Risk factors like recent antibiotic use and proton pump inhibitors increase susceptibility, underscoring the importance of antibiotic stewardship. Fidaxomicin is now the preferred first-line therapy for initial CDI episodes, valued for its ability to reduce recurrence, while vancomycin remains a cost-effective alternative.
Advances in managing recurrent and severe cases include extended tapering regimens, fecal microbiota transplantation (FMT), and bezlotoxumab for high-risk patients. For fulminant CDI, high-dose oral vancomycin, with or without IV metronidazole, remains standard and often requires surgical consultation. Nurse practitioners play a vital role in applying updated guidelines to reduce morbidity, prevent recurrence, and improve outcomes. Early diagnosis, personalized treatment, and multidisciplinary care are key to effectively addressing CDI’s burden.
