ACTH Stimulation Test

• With the recent publication of the CORTICUS study (along with others), it is becoming clear that the ACTH stimulation test is not reliable in identifying patients with adrenal insufficiency
• In fact, the test is no longer recommended in the evaluation of patients with severe sepsis/septic shock
• Furthermore, if you decide to give steroids to the patient with severe sepsis/septic shock, there is no need to use dexamethasone for fear of "disrupting the ACTH stim test" (hydrocortisone is the preferred agent)
