Background: Early-onset neonatal sepsis, defined as sepsis within 72 hours of birth, results in significant infant morbidity and mortality. Readmissions associated with neonatal sepsis have not previously been well described. Early-onset neonatal sepsis is a mandatory reportable condition in Connecticut, allowing for expanded data collection through public health surveillance to evaluate readmissions. Methods: Infants with early-onset neonatal sepsis born in Connecticut during 2007-2016 were identified from statewide surveillance data and matched with a statewide hospital discharge database. We describe readmission rates, causes and timing of readmissions, and demographic and clinical factors associated with readmission among this group. Results: Among 241 infants with early-onset neonatal sepsis matched to discharge data, 203 (84.2%) infants survived their initial hospitalization at birth. During the first year of life, 47 (23.2%) infants were readmitted, most often in the first 3 months after birth (n = 29, 42.6%). The most frequent reasons for readmissions were pulmonary complications (19%), infections (17%), and gastrointestinal illness (13%). Infants with initial hospitalizations lasting longer than 30 days after birth were associated with higher rates of readmission compared with those discharged within 30 days after birth (35% vs 19%, P =. 02). Conclusions: A substantial proportion of infants diagnosed with early-onset neonatal sepsis are readmitted within the first year of life. Those with prolonged hospitalizations after birth are at the highest risk. Further efforts and intensified strategies are needed to prevent readmissions among this vulnerable patient population.
