Frequency of In-Hospital Acquired Staphylococcus Bacteremia/Sepsis Within Ten-year Period

Aida Pitic, Enra Lukovac, Nada Koluder, Rusmir Baljic.

Abstract
Analyzing data in the literature, it is noted that in-hospital acquired infections are an increasing problem even in more developed countries. This increasing trend is related to the progress of medical science and introduction of new invasive diagnostic-therapeutic methods, as well as increase of multiresistant types of bacteria, including staphylococci in big percentages. Goals: To analyze frequency of in-hospital acquired staphylococcus bacteremia/sepsis. Patients and methods: Anamneses of patients who were diagnosed with staphylococcus bacteremia/sepsis were analyzed within a ten-year period. Results: Within the analyzed period from 2001 to 2011, there were 87 patients with diagnosis of staphylococcus bacteremia/sepsis, out of which (20) 77% were diagnosed with sepsis, and (67) 23% with bacteremia. In-hospital outcome was present with 32 (36.8%) patients, while 55 (63.2%) were out of hospital. The chi-square test for independence showed that the diagnosis of bacteremia/sepsis and the place of the infection origin (in hospital/out of hospital) were independent c2 = 1.951 df= 1 p= 0.162. The cause isolated from hemoculture depends on the place of the infection origin (out of hospital/in hospital); larger percentage of methicillin-resistant types was presented in in-hospital acquired infections c2 =11.352 df= 1 p=0.001. And the chi-square test for independence showed both dependence of the preceding antibiotic treatment and the place of the infection origin in both categories of patients. Sepsis: c2 = 22.92 df= 1 p

Key words: hospital infections, staphylococcus bacteremia/sepsis, antibiotic therapy
