Introduction. Healthcare-associated infections are a frequent and severe complication in newborns with very low birth weight (NBVLBW). Objective. To describe the clinical and microbiological characteristics of these infections in newborns weighing between 500 and 1 499 grams at the National Maternal and Perinatal Institute. Methods. A descriptive, retrospective, and cross-sectional study was conducted in Lima in 2024. A total of 266 newborns with confirmed diagnosis were included. Results. The infection rate was 13.9 %. Mortality reached 71.4 % in newborns weighing 500 to 999 grams and 19.8 % in those weighing 1 000 to 1 499 grams. Central venous catheters were involved in 68.7 % of cases. The most frequent pathogens were Staphylococcus coagulase-negative and Staphylococcus haemolyticus. Gram-negative bacilli showed higher lethality and resistance to multiple antimicrobial agents. Conclusion. Infections in NBVLBW are closely associated with the use of invasive devices and the presence of multidrug-resistant pathogens, requiring improved prevention and surveillance.
