Background: Early infection identification may improve outcomes in obstetric patients. However, obstetric vital signs and laboratory values differ from the non-pregnant, possibly limiting current sepsis score use. Thus, we evaluated sepsis score use in peripartum infection. Methods: This case-control study evaluates sepsis criteria fulfilment in preterm premature rupture of membranes (PPROM) – at high infection risk– versus in elective caesarean delivery (CD) – at low risk. The study was perfoemd at the departement of obstetrics & gynecologt at Shaare Zedek Medical Center, a 1000-bed university-affiliated acute care hospital. We inlcuded women with PPROM undergoing CD (n=453) at gestational weeks 24-36 versus those undergoing elective term CD (n=2004). The primary and secondary outcome measures were SIRS and qSOFA criteria fullfilment and availability of the score components and clinical intraamniotic infection and positive cultures rates. Results: At admission 14.8% of the study group and 4.6% of control met SIRS criteria (p=0.001), as did 12.5% and 5.5% on post-operation day (POD) 1 (p=0.001), with no significant differences on POD 0 or 2. In the study group more cultures (29.8% versus 1.9% – cervix; 27.4% versus 1.1% – placenta; 7.5% versus 1.7% – blood; p=0.001 – all differences) and more positive cultures (5.5% versus 3.0% – urine – p=0.008; 4.2% versus 0.2% – cervix – p=0.001; 7.3% versus 0.0% – placenta – p=0.001; 0.9% versus 0.1% – blood – p=0.008) were obtained. 10.6% of the study group and 0.4% of control met criteria for intraamniotic infection (p=0.001). Conclusions: Though significant difference was noted in SIRS criteria fulfilment in the study group versus control, there was considerable between-group overlap, questioning utility of SIRS in intraamniotic infection diagnosis. |
