ABSTRACT

Objective: To identify factors associated with hospital stay at the time of detecting a nosocomial infection in newborns from an Intermediate Care Unit. Material and methods: We analyzed maternal, neonatal, and epidemiological history of 92 newborns hospitalized during 2007 at a highly specialized Perinatal Care Center located in Mexico City, where 114 events of nosocomial infections were detected by an active Epidemiologic Surveillance. Descriptive measures were calculated and two groups of patients were formed based on the median length between admission and the time (10 days) in which a nosocomial infection was detected. For the intergroup contrast, Odds Ratio (OR) and Z-, F-, t-tests were applied. Results: Nosocomial infections that occurred within the first 10 days of stay were associated with specific risks such as respiratory distress (OR 3.26), hyperbilirubinemia (OR 7.19), and isolation of Gram-positive microorganisms (OR 3.09). In nosocomial infections that occurred after 10 days of hospitalization, it was found that birth defects (OR 2.2), infections by Gram-negative bacilli (OR 3.26), and had been hospitalized in various services (OR 2.89) are statistically significant risk factors. Conclusions: Knowing the relationship between risk factors and hospital stay at the time of detecting nosocomial infection, allows to emphasize preventive measures.
