Abstract

Healthcare-associated infections (HAI) continue to be a major public health concern. A number of epidemiologically relevant HAI microorganisms are multidrug-resistant (MDR) germs that can spread rapidly and/or carry multiple resistance to antibiotics. They are the cause of high mortality and possible nosocomial epidemics. For this reason, we implemented microbiological surveillance acquiring samples from patients with HAI and environmental samples from the surfaces surrounding those patients. A retrospective study was carried out from January 2014 to December 2016 in two departments of the University Hospital in Messina, Italy: the Microbiology and the Hygiene Laboratories. A comparison was made between the microbiological isolates found on the patients and the microorganisms typed further to environmental sampling on the surfaces adjacent to the patient with HAI. There was a 24% match in 2014, 22% in 2015 and 20% in 2016 on total isolates. The most common isolates belonged to the Enterobacteriacae family: in particular, an ever-increasing trend has been registered for Klebsiella spp; Acinetobacter baumannii and multiresistant Pseudomonas aeruginosa have seen a growing trend for both patient and environmental samples. During the three years, the highest infection prevalence rate was found in Anaesthesia and Resuscitation, followed by Thoracic and Vascular Surgery.
