Diagnostic performance and patient outcomes with c-reactive protein use in early-onset sepsis evaluations.
This study’s objective was to determine performance of C-reactive protein (CRP) in the diagnosis of early-onset sepsis, and to assess patient outcomes with and without routine use of CRP in infants in the neonatal intensive care unit (NICU). This retrospective cohort study looked at infants admitted to 2 NICUs from 2009 to 2014. During the time period, 10,134 infants were admitted, 89.9% had CRP, and 74.5% had blood culture obtained within 3 days of birth. CRP obtained plus/minus 4 hours had a sensitivity of 41.7%, specificity 89.9%, and positive likelihood ratio 4.12 in diagnosis of early-onset sepsis. When obtained 24-72 hours after blood culture, sensitivity of CRP increased significantly (89.5%), but specificity (55.7%) and positive likelihood ratio (2.02) decreased. Comparing the periods with (n = 4977) and without (n = 5135) routine use of CRP, the authors observed lower rates of early-onset sepsis evaluation (74.5% vs 50.5%), antibiotic initiation (65.0% vs 50.8%), and antibiotic prolongation in the absence of early-onset sepsis (17.3% vs 7.2%) in the later period.
