Current clinical management guidelines for Clostridium difficile infection (CDI). This diagram reviews the recommended treatment approaches for primary and recurrent CDI, depending on disease severity based on the 2018 IDSA/SHEA guidelines. Additionally, there is some evidence for fidaxomicin in place of rifaximin as a chaser for recurrent CDI and the EXTEND trial did show evidence for using extended-pulsed fidaxomicin for primary CDI; however, this is not currently reflected in the guidelines9,33,34,137.
* Primary CDI is defined as a new episode of symptoms with no previous positive C. difficile test result within 38 weeks and confirmation of CDI by diagnostic testing.
