What are the main management steps for suspected C. difficile infection?

• A. Isolate patient; discontinue unnecessary antibiotics; obtain stool testing; initiate vancomycin or fidaxomicin based on severity
• B. Discontinue isolation; start antibiotics
• C. Do nothing
• D. Order imaging only

Answer: (A)

Managing suspected C. difficile infection centers on preventing transmission, stopping the antibiotic trigger, confirming the diagnosis, and treating based on severity. Because C. difficile spores spread easily, use contact precautions and reinforce hand hygiene with soap and water to reduce spread. Stopping unnecessary antibiotics removes the ongoing disruption of gut flora that allows the organism to thrive and produces toxins, helping the patient recover. To confirm the diagnosis, obtain stool testing for C. difficile toxins or a nucleic acid amplification test when diarrhea is present, so treatment can be appropriately directed. Once CDI is suspected and confirmed, initiate therapy with oral vancomycin or fidaxomicin, choosing the regimen based on severity. This approach targets both the infection itself and the transmission risk, aligning treatment with current best practices.
