Evaluation of the systemic inflammatory response syndrome criteria for the diagnosis of sepsis due to maternal bacteremia.

OBJECTIVE

To examine, in the setting of maternal bacteremia, the implications for the diagnosis of maternal sepsis of customizing the systemic inflammatory response syndrome (SIRS) criteria for physiologic changes of pregnancy.

METHODS

Women with maternal bacteremia in a tertiary maternity hospital during 2009-2014 were identified. Records were retrospectively reviewed to determine whether they fulfilled the criteria for diagnosis of sepsis based on either the standard SIRS parameters derived from the Surviving Sepsis Campaign or SIRS parameters customized for pregnancy. Diagnosis of sepsis was based on the presence of two or more SIRS criteria, in conjunction with infection, during the hour before and the 6 hours after phlebotomy for blood culture.

RESULTS

Of 93 women with bacteremia, 61 (66%) would have been diagnosed with sepsis based on standard criteria compared with 52 (56%) based on customized criteria (P=0.18). Seventeen women had a diagnosis of sepsis based on the standard but not the customized criteria, while eight women had sepsis based on the customized but not the standard criteria.

CONCLUSION

In maternal bacteremia, customized SIRS criteria do not increase the rate of diagnosis of sepsis. Prospective studies should investigate whether the introduction of customized SIRS criteria can improve clinical outcomes.
