ABSTRACT
Introduction. Health care-associated infections are a frequent adverse
effect. Neonates are an affected population group due to their immune immaturity.
The World Health Organization estimates that these infections vary between 5% to
25% depending on the income level of each country. In Colombia these infections
are underreported, particularly in neonates. The aim of this review was to identify the
risk factors, the most common microorganisms, and the routes of transmission for
these type of infections in neonates, as reported in the world literature.
Methodology.
A systematic duplicate search was carried out in PubMed, with articles published
between 2014 to 2019, which included a search for articles, reading and exclusion
of duplicates, reconciliation between authors, and quality assessment.
Results. The
level of evidence and the grade of recommendation was optimal in general (levels
1 and 2, recommendation A and B). The most common risk factors were prematurity
and low birth weight, the use of central venous catheter, mechanical ventilation, prolonged
hospital stay, and long-term use of antibiotics. Microorganisms such as coagulase
negative Staphylococcus and Serratia marcenscens were reported, and common
routes of transmission such as the bloodstream, respiratory tract, gastrointestinal tract,
and skin were described.
Conclusion. Health care-associated infections are more frequent
than estimated, and can be prevented with the adoption of health policies,
such as proper hand washing, disinfection of environmental surfaces and medical
equipment, an adequate skin care of the neonate, and isolation protocols for patients
with these infections.
