Abstract

Background:

Current guidelines for septic shock management recommend administration of appropriate, broad-spectrum antimicrobials within 1 hour of recognition.

Objective:

To evaluate the interventions pharmacists make as part of a sepsis response team and to determine if these interventions increase the proportion of patients with appropriate empiric antimicrobial therapy.

Methods:

A retrospective cohort study was undertaken reviewing adult patients in a large, academic medical center with confirmed septic shock who had an order for a “sepsis bundle,” which includes notification of a pharmacist to assess adequacy of empiric therapy. Pharmacist interventions with regard to selection of empiric antimicrobials were documented. The proportion of patients with initial successful selection of antimicrobial therapy (SSAT) before and after pharmacist intervention was assessed as well as the time to first antimicrobial administration and time to appropriate antimicrobial administration.

Results:

A total of 76 patients were included. Pharmacist intervention increased the proportion of patients with SSAT from 66% to 80% (P = .04). Median time to first antimicrobial administration was 43 minutes, and time to appropriate antimicrobial therapy was 1 hour, 34 minutes for the entire cohort, with pharmacist intervention decreasing the latter time significantly in patients without SSAT on initiation of the “sepsis bundle” (P < .001).

Conclusion:

Pharmacist assessment of patients in septic shock offers the opportunity to improve SSAT. Systems designed to use a pharmacist responder for the care of patients with septic shock maximize the selection of antimicrobials, facilitate rapid administration, and improve surrogate outcomes for mortality in septic shock.
