Background: The SEP-1 measures have tied financial reimbursement to the treatment of patients with severe sepsis and septic shock. The purpose of this study was to assess the impact of a SEP-1 initiative on the utilization of broad-spectrum combination therapy (BSCT) in the emergency department (ED).
Methods: This was an IRB-approved, retrospective evaluation of adult patients who received vancomycin plus an antipseudomonal beta-lactam for a urinary tract infection (UTI) or skin or soft tissue infection (SSTI) in the ED. The primary outcome was the proportion of patients in which use of BSCT was considered appropriate based on clinical criteria. Secondary outcomes included door to antibiotic order time, door to administration time, proportion of patients continued on BSCT upon admission, duration of BSCT, and in-hospital mortality.
Results: A total of 400 patients were included in the analysis. Following SEP-1 implementation, appropriate use of BSCT decreased by 12%, with 54% of patients in the pre-SEP-1 group meeting clinical criteria compared to 42% in the post-SEP-1 group (p = 0.028). In the subgroup of patients with a suspected UTI the appropriate use of BSCT declined by 25% (40% vs 15%, p = 0.005). The median door to first antibiotic administration time was not significantly different between groups (63 min vs 61 min, p = 0.091).
Conclusions: The implementation of the SEP-1 mandated measures was associated with an increase in the unnecessary use of BSCT. Additionally, no difference was seen in time to antibiotic administration. The results of this study demonstrate the negative impact that the SEP-1 mandate may have on antimicrobial utilization within the ED.
