Clostridioides difficile infection (CDI) is associated with significant morbidity and mortality within the Australian population. Treatment recommendations for CDI pose challenges at both community and hospital-based levels due to the recurrent, refractory and potentially severe nature of the disease. Since the last published Australasian guidelines in 2016, new therapeutic options are available, prompting a necessary update to management recommendations. On behalf of the Australasian Society of Infectious Diseases, we present the updated guidelines for the management of CDI in adults and children exploring the changes to treatment recommendations - including the replacement of oral metronidazole with vancomycin for initial CDI and the emerging role for fidaxomicin and faecal-microbiota transplant.
