Nosocomial Infection agents of Şişli Hamidiye Etfal Training and Research Hospital; Comparison of 1995 and 2017 data

Abstract

OBJECTIVES: Healthcare-associated infections (HCAI), which are important causes of mortality and morbidity, are high cost but preventable infections. This study aimed to determine hospital infections and isolates in Şişli Hamidiye Etfal Training and Hospital and to determine our local data. The changes in the distribution of the isolates in this process were evaluated by comparing the data of 1995 and today. METHODS: Materials sent to the microbiology laboratory of our hospital in 1995 and 2017 from the patients hospitalized in the period between June 1-December 31 were evaluated concerning hospital infection. The standard manual methods were used in 1995, while in 2017, MALDI-TOF MS was used for identification and BD Phoenix automated system for antibiotic susceptibility. RESULTS: In 1995, in total, 100 bacteria were isolated from pediatric and adult patients, of which 48 Pseudomonas aeruginosa (48/100), 37 Klebsiella spp (37/100). In 2017, Acinetobacter baumannii causing an important resistance problem was found to be increased in number. The main hospital infection causes were Acinetobacter baumannii (37/179), Klebsiella spp (41/179). In 2017, bacterial diversity was also increased. CONCLUSION: Isolated strains, as in the past, are gram-negative bacteria, Pseudomonas spp decreased in 2017, and Acinetobacter spp increased. The findings suggest that the automated systems used in microbiology laboratories may have a role in the detection of bacterial diversity.
