Aim:
Healthcare-associated infections cause increased morbidity and mortality in intensive care units. In this study, it was aimed to compare infections with multi-drug resistance and extended drug resistance, while evaluating the characteristics of resistant Gram-negative infections in the pediatric intensive care unit in our university hospital.
Material and Methods:
In this study, pediatric patients who were found to have Gram-negative infections during hsopitalization in the pediatric intensive care unit in our faculty between January 2011 and December 2015, were evaluated retrospectively.
Results:
One thousand thirty patients were internalized in our unit in the study period. The incidence for healthcare-associated infection was found as 17.2% and the incidence density was found as 32.7 per 1000 patient days. The incidence for healthcare-related infection per 1000 device days and the rate for device use were calculated as 66.9 and 0.59, respectively. One hundred thirty Gram-negative infection episodes were found in 79 patients whose median age was 22 (1–205) months. The most common infections included ventilator-related pneumonia (n=78, 60%) and bloodstream infections (n=38, 29.2%). The most common causative agents included
Pseudomonas aeruginosa
(n=50, 38.5%),
Kleibsiella pneumonia
(n=32, 24.6%) and
Acinetobacter baumannii
(n=28, 21.5%). Among
A. baumannii isolates
, the rates for resistance against piperacillin-tazobactam and meropenem were found as 96.4% and 89.3%, respectively. Empirical use of carbapenems, aminoglycosides, and fluoroquinolones, the presence of total parenteral nutrition and history of Gram-negative bacterial infections prior to pediatric intensive care unit admission were significantly more common among extended-drug Gram-negative bacterial infections. The late mortality rate was found to be higher in presence of extended drug resistance. History of Gram-negative infection was found to be an independent risk factor in terms of extended drug resistance.
Conclusion:
Healthcare-associated infections are an important health problem and it is important for infection control committees of hospitals to determine and apply strategies according to hospital colonization in prevention.
Climate change is a result of natural processes and human-made activities influencing the atmosphere. Many infectious diseases are climate-sensitive and their nature and epidemiology are changing in parallel with the change in climatic conditions and global warming. Increased replication rates of pathogens at higher temperatures, extended transmission seasons, migration of vectors or human populations are some outcomes of the changing climate, to trigger new concerns including new epidemics with old or new pathogens. Climate change is presenting itself today as an urgent global health threat and it requires immediate international action with high priority. Infectious diseases in relation to changing climatic conditions are reviewed with predominating current examples, keeping a focus on Europe with particular emphasis on South-Eastern European and Eurasian regions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
