Sepsis is a leading cause of mortality for neonates in developing countries; however, little research has focused on clinical predictors of nosocomial infection of preterm neonates in the low-resource setting. We sought to validate the only existing feasible score introduced by Singh  et al.  in 2003 and to create an improved score. In a secondary analysis of daily evaluations of 497 neonates ≤33 weeks gestational age admitted to a tertiary care NICU in Dhaka, Bangladesh, we tested the Singh score and then constructed and internally validated our own bedside predictive score. The Singh score had low sensitivity of 56.6% but good positive predictive value (PPV) of 78.1% in our sample. Our five-sign model requiring at least one clinical sign of infection (apnea, hepatomegaly, jaundice, lethargy and pallor) had an area under the receiver operating characteristic of 0.70, sensitivity of 77.1%, and PPV of 64.9%. Our clinical sepsis score is the first bedside clinical screen exclusively for hospitalized, very premature neonates in a low-resource setting, and warrants external validation.
