Multiresistant microorganism infection in newborns at an intermediate neonatal care unit and intensive care unit of reference: cross-sectional study

Abstract

The objective was to describe the infection profile of multidrug-resistant organisms of newborns (NB), admitted to the neonatal intermediate care unit and the intensive care unit. It was a descriptive cross-sectional study of epidemiological nature, composed of 931 medical records and/or Hospital Infection Control Committee notification records, during the period of June to September 2012. Eight hundred and seventy newborns (NB) were admitted to the neonatal intensive care units and to intermediate care, with a final sample of 45 NB presenting bloodstream infections (BSI) caused by multiresistant microorganisms. From the analyses, the following results were highlighted: gestational age < 37 weeks in 42 (93.3%); low weight at birth between < 750g to 1.499g. The profile for resistance to enterobacteriaceae was 100% for cefepime and ceftazidime concerning non-fermenting gram-negative bacteria, it was found that (100%) of P.aeruginosa was resistant to aztreonam, (100%) of S. maltophilia resistant to ceftazidime and to gentamycin, however, (1.1%) of S. aureus isolates were resistant to oxacillin and (12.5%) of S. haemolyticus demonstrated a confirmed resistance to vancomycin. These results are worrying and express the importance of correct monitoring, and the need for producing a propaedeutic protocol in consensus with the multiprofessional team through the Hospital Infection Control Committee and managers, which is then implemented and regularly assessed by the service.
