[Notification of healthcare associated infections based on international criteria performed in a reference neonatal progressive care unity in Belo Horizonte, MG].

Objective: To describe occurrence of Healthcare Related Infections in a neonatal unit of public reference service in Belo Horizonte-MG, based on international criteria.
Methods: This is a descriptive study, performed by active searching, in the Progressive Care Unit Neonatal Hospital das Clinicas, Federal University of Minas Gerais (HC / UFMG), from 2008 to 2009. Notification of infections was based on National Healthcare Safety Network (NHSN) criteria. The database and analysis were performed in a internal program.
Results: A total of 325 episodes of infection in newborns were notified and overall incidence density of infections was 22.8/1,000 patient-days, with a rate of 36.7% of newborns. Sepsis was the main infection (62.5%) reported. The incidence density of infections was higher in neonates weighing lower than 750g (42.4/1,000 patient-days). There were 18.15 episodes of central venous catheter related sepsis/1,000 central venous catheter-day and 19.29 umbilical catheter related sepsis /1,000 umbilical catheter-days. Microorganisms were isolated in 122 (37.5%) cases of reported infections, mainly defined as Staphylococcus coagulase negative and Staphylococcus aureus (51 cases). Mortality and lethality rates were 4.3% and 17,12%, respectively.
Conclusion: The use of standardized criteria for reporting infections is necessary for the construction of indicators in neonatology, which are scarce in the country and highlight the need for evaluation of national criteria proposed by National Agency of Sanitary Surveillance (ANVISA).
