Background: Febrile infants aged 0 to 60 days are often hospitalized for a 36-to-48 hour observation period to rule out invasive bacterial infections (IBI). Evidence suggests that monitoring blood and cerebrospinal fluid (CSF) cultures for 24 hours may be appropriate for most infants. We aimed to decrease the average culture observation time (COT) from 38 to 30 hours among hospitalized infants 0 to 60 days old over 12 months.
Methods: This quality improvement initiative occurred at a large children's hospital, in conjunction with development of a multidisciplinary evidence-based guideline for the management of febrile infants. We included infants aged 0 to 60 days admitted with fever without a clear infectious source. We excluded infants who had positive blood, urine, or CSF cultures within 24 hours of incubation and infants who were hospitalized for other indications (eg, bronchiolitis). Interventions included guideline dissemination, education regarding laboratory monitoring practices, standardized order sets, and near-time identification of failures. Our primary outcome was COT, defined as time between initiation of culture incubation and hospital discharge in hours. Interventions were tracked on an annotated statistical process control chart. Our balancing measure was identification of IBI after hospital discharge.
Results: In our cohort of 184 infants aged 0 to 60 days, average COT decreased from 38 hours to 32 hours after structured guideline dissemination and order-set standardization; this decrease was sustained over 17 months. IBI was not identified in any patients after discharge.
Conclusions: Implementation of an evidence-based guideline through education, transparency of laboratory procedures, creation of standardized order sets, and near-time feedback was associated with shorter COT for febrile infants aged 0 to 60 days.
