Evolución de la incidencia de pacientes con colonización e infección por bacterias productoras de carbapenemasas VIM en un hospital pediátrico en España
Rev Esp Quimioter. 2019 Feb;32(1):60-67.
OBJECTIVE: The aim of this study is to describe the evolution of the incidence of infected and colonized patients with carbapenemase VIM-producing bacteria (CPB-VIM) at a national referral pediatric center in Madrid, Spain, between 2012 and 2015. METHODS: Descriptive epidemiological surveillance study. The surveillance system included case detection (screening for BPC colonization in all admitted patients, with periodicity according to the ward) and control measures (contact precautions, identification of previously colonized patients at admission, environmental cleaning, education, supervision of contact precautions, and patient cohort). All hospitalized patients with first positive microbiological sample for CPB-VIM in 2012-2015 were included. Colonized patients were followed through clinical history to evaluate later infection. RESULTS: We found 239 colonized and 51 infected patients with CPB-VIM (49.3% women, 47.6% were 5 months old or younger, 52.1% admitted at Intensive Care Unit). Infection and colonization incidence were, respectively, 2.6 and 6.7 cases per one thousand hospitalized patients in 2012, 1.8 and 10.0 in 2014 and 0.3 and 5.0 in 2015. Within these patients, 84.4% shared ward with other patient with previous positive sample. 13.0% (31/239) of colonized patients had a subsequent infection. CONCLUSIONS: We have shown data of pediatric patients affected by BPC-VIM, collected from an epidemiological surveillance system that included systematic screening at a national referral center. After an epidemic period, the incidence of cases went down. The surveillance and infection control measures intensification, as well as coordination with involved departments, were key in the handling of the situation.
