Risk Factors Of Nosocomial Infection

Nosocomial infections are one of the major causes of morbidity in the Newborn Intensive Care Unit (NICU). The U.S. Center for Disease Control and Prevention (CDC) explains Nosocomial Infection as an infection that occurs 48-72 hours after the admission of a person in the hospital, due to microbial agents either of the patient’s microbial flora or the hospital environment (CDC, 2011). Known risk factors include birth weight, gestational age, severity of illness and treatment, and instrumentation. Infections result in prolonged hospital stays and, consequently, increased hospital costs. As advances in medical technology improve mortality in the tiniest of infants, it is imperative that health care providers identify effective interventions to …show more content…
This study was conveyed in order to record and describe the risk factors for nosocomial infections associated with neonates hospitalized in NICUs. However, the risk factors, which include birth weight, gestational age, severity of illness and treatment, and instrumentation are the means for generating hypotheses to guide quasi-experimental and experimental studies that do focus on examining cause and effect relationships.
Researchers kept a record card of nosocomial infections which organized the instrument of the study. The card-instrument of the study included data about Demographics, Consumption of Antibiotics, Infections’ Surveillance (presence of infection, Microorganism Identity, Risk Factors), Clinical Identification of the Infection, Laboratory Confirmation of the

Additionally, in the case of a nosocomial infection, the gestational age was considerably lower, as well as the weight of the neonates, at birth and the admission to the NICU. Correspondingly, a nosocomial infection prolonged the duration, expressed in days, of the intravenous therapy, of intubation, of all central catheters. It became obvious that the kind of unit, the prematurity of the neonate, the duration of intravenous therapy and the duration of hospitalization were independently related with the occurrence of nosocomial infection. Therefore, neonates hospitalized in an open unit were 3.37 times more probable to develop a nosocomial infection, paralleled with those hospitalized in a closed unit. Respectively, neonates with gestational age lower than 29 weeks were 4.46 times more likely to progress a nosocomial infection, compared with those who were not born
