Introducere. Respectarea regimului igienic şi antiepidemic în cadrul IMSP este un element important în controlul infecţiilor intraspitaliceşti. Scopul lucrării. Aprecierea peisajului microbiologic al mediului spitalicesc pe modelul Spitalului Clinic de Traumatologie şi Ortopedie (SCTO). Material şi metode. Studiul este unul transversal, bazat pe o analiză retrospectivă a datelor colectate din laboratorul bacteriologic al SCTO, pe perioada anilor 2009-2014. Rezultate. În decursul a 6 ani, în SCTO au fost prelevate 8472 probe, dintre care 350 au fost pozitive (4,13%). Din lavaje a fost izolată următoarea structură etiologică: S. epidermidis – 73,14%, Bacterii coliforme – 10,56%, S. aureus – 9,72%, E. coli – 4,29% şi P. aeruginosa – 2,0%. În funcţie de locaţia izolării, tulpinile de E. coli au fost depistate în secţiile: chirurgicale – 40,0%, reanimare – 26,67%, şi sălile de operaţie – 6,66%. Tulpinile de S. epidermidis au fost decelate în secţiile: chirurgicale – 51,37%, şi reanimare – 27,45%. Tulpinile de S. aureus au fost izolate în secţiile: reanimare – 44,12%, chirurgicale – 29,41% şi în sălile de operaţie 17,65%. Tulpinile de P. aeruginosa au fost depistate doar în secţiile: chirurgicale –85,72% şi reanimare – 14,28%. Cele mai multe culturi de microorganisme au fost izolate în secţiile: chirurgicale – 43,71%, reanimare – 25,71%, sălile de operatie – 13,15%. Raportînd la numărul de probe colectate, mai multe probe pozitive au fost înregistrate în secţiile de reanimare – 13,0%, secţiile chirurgicale – 5,28% şi sălile de operaţie 1,70%. Concluzii. Din mediul spitalicesc al SCTO au fost depistate 350 de microorganisme condiţionatpatogne. Cele mai înalt contaminate secţii s-au dovedit a fi cele de reanimare şi chirurgicale.

Introduction. Compliance with hygienic and antiepidemic regimen in the PMI is an important element in the hospital infection control. Objective of the study. To assess the microbiological landscape based on the model of Traumatology and Orthopedics Hospital (TOH). Material and methods. Transversal study is based on a retrospective analysis of data collected from the bacteriological laboratory of TOH, during 2009-2014. Results. In the course of 6 years, in TOH there were collected 8472 tests, of which 350 were positive (4,13%). The following etiological structure was isolated from the lavage: S. epidermidis – 73,14% Coliform bacteria – 10.56%, S. aureus – 9.72%, E. coli – 4.29% and P. aeruginosa – 2.0%. Depending on the location of isolation, E. coli strains were detected in the following departments: surgical – 40,0%, reanimation – 26.67%, and operating rooms – 6.66%. The strains of S. epidermidis were found in following departments: surgical – 51.37% and reanimation – 27.45%. The strains of S. aureus were isolated in following departments: reanimation – 44.12%, surgical – 29.41%, and operating rooms – 17.65%. P. aeruginosa strains were found only in following departments: surgical – 85.72% and reanimation – 14.28%. Most strain of microorganisms were isolated in the following departments: surgical – 43.71%, reanimation – 25.71%, and operating rooms – 13.15%. Reporting to number of samples collected, several positive samples were registered in reanimation department – 13.0%, followed by surgical departments – 5.28% and operating rooms – 1.70%. Conclusions. There were detected 350 pathogenic–conditioned microorganisms in the hospital environment. The department of reanimation and surgery were the most contaminated of all.
