An Institutional Approach to the Management of Asymptomatic Chorioamnionitis-Exposed Infants Born ≥35 Weeks Gestation.

Abstract

We compared 123 chorioamnionitis-exposed infants born 1 year before implementation (pre-algorithm group, April 1, 2016, to March 31, 2017) with 111 born 1 year following implementation (post-algorithm group, April 1, 2017, to March 31, 2018). The primary outcome measure was analyzed monthly using a run chart. The maternal and neonatal characteristics were similar between both groups. Significantly fewer infants in the post-algorithm group received antibiotics compared with the pre-algorithm group (4.5% versus 96.8%; P < 0.01). There were no differences in median hospital length of stay or incidence of neonatal intensive care unit admissions between both groups. There were no positive blood cultures or readmissions within 7 days for early-onset sepsis in either group. An institutional approach of monitoring chorioamnionitis-exposed infants with a clinical and laboratory evaluation decreased antibiotic utilization in the mother-baby unit by 95% without an increase in hospital length of stay, neonatal intensive care unit admissions, or readmissions for early-onset sepsis.
