HealthDay News — For patients with vasopressor-dependent septic shock, early hydrocortisone use is associated with improved outcomes, according to a study published online Sept. 2 in SHOCK.

Gretchen L. Sacha, Pharm.D., from the Cleveland Clinic, and colleagues compared clinical outcomes in 1470 patients with septic shock who received hydrocortisone, based on timing of initiation after shock onset.

The researchers found that 38.6, 15.7, 17.7, 13.3, and 14.8 percent of patients received hydrocortisone at zero to six, six to 12, 12 to 24, 24 to 48, and more than 48 hours after shock onset, respectively. On univariate analysis, there was no significant difference in days alive and free from vasopressors among the timing groups; intensive care unit (ICU) mortality also did not differ. Timing of hydrocortisone was independently associated with more days alive and free from vasopressors when comparing initiation within zero to six, six to 12, and 12 to 24 hours with initiation within more than 48 hours (beta coefficients, 2.8, 2.5, and 2.3 days) on multivariable logistic regression. When comparing receipt within zero to six hours with receipt within more than 48 hours after shock onset, timing of hydrocortisone was associated with reduced ICU mortality (odds ratio, 0.6).

“If hydrocortisone is to be initiated in patients with septic shock, it should be initiated within at least the first 24 hours after shock onset, and ideally within the first 12 hours,” the authors write.
