ObjectiveThe most common admission to intensive care nurseries is the infant with suspected neonatal sepsis. To determine the clinical practice of neonatologists with respect to this diagnosis, we examined a large neonatal database during a 2-year period of time. The goal of this study was to define whether there were optimal practice strategies that could identify a "benchmark" clinical approach for this diagnosis.DesignThe PROACT database of ParadigmHealth was examined for all term infants with an admitting ICD - 9 code for suspected neonatal sepsis between January 1, 2001 and December 31, 2002. Infants had to be asymptomatic by 24 hours of life with no significant respiratory signs and receiving oral feedings. All infants had negative blood cultures. Maternal risk factors were examined to determine if they influenced the duration of therapy. The impact of treatment upon subsequent length of stay was also evaluated. Several areas of the country were individually examined to see if possible regional variations existed with respect to treatment of suspected sepsis.ResultsThere were no significant differences noted in the management when maternal risk factors for suspected sepsis were assessed. In general, neonates were treated for 3.3+/-1.8 to 3.5+/-2.1 days, regardless of the number of maternal risk factors present at birth (p=NS). Length of stay ranged from 4.2+/-2.1 to 4.4+/-1.9 days in these groups (p=NS). The duration of treatment ranged from 1 to 10 days, even though all infants were clinically well and feeding by 24 hours of life. A total of 170 infants (17.0%) were treated for 4 to 6 days and 116 (11.6%) neonates received antibiotics for 7 to 10 days, even with negative blood cultures. One region of the country appeared to treat infants for a longer period of time than the other four regions examined, increasing the mean length of stay by 1.8 days (p<0.05).ConclusionsTreatment of neonates with suspected sepsis appears to be influenced by considerations other than maternal risk factors or the infant's clinical condition beyond the first day of life. There appears to be a great deal of practice variation among neonatologists confronted by patients with suspected sepsis. Awareness of this unnecessary variation may be of great value in reducing the duration of antibiotic therapy in the NICU and shortening the length of stay.
