Bacterial Profiles And Antibiotic Sensitivity Pattern Of Isolates From Medical Devices And Inanimate Surfaces From Icu Room At Yekatit 12 Hospital Medical College Addis Ababa Ethiopia.

Background: Infections acquired in hospitals are a major public health concern around thernworld, especially when caused by multidrug-resistant (MDR) microorganisms. Bacteria,rnincluding MDR isolates, were found in critical care units near the patient or nearbyrnenvironment (inanimate surfaces and equipment). Microorganisms may be transmittedrnindirectly via inanimate surfaces and equipment, which could play a substantial role in ICUrelatedrninfections.rnrnrnObjective: To assess bacterial profile and antibiotic sensitivity pattern of isolates from medicalrndevices and inanimate surfaces of ICU room at Yekatit 12 Hospital Medical College, AddisrnAbaba, Ethiopia. rnMethods: A hospital-based cross-sectional study was conducted from April to June 2021 inrnYekatit 12 Hospital Medical College in Addis Ababa. Swabs were collected twice in 30 daysrnfrom medical devices and inanimate surfaces of ICU room. A total of 136 samples wererncollected by swabbing hospital surfaces, and the bacterial isolates were identified using Gram'srnstaining, standard culture, and biochemical tests. Besides, the respective antimicrobialrnsensitivity tests were checked for antibiotic susceptibility using the Kirby–Bauer diskrndiffusion. SPSS Version 25 was used to analyzed and present the results in terms of percentagernand table. rnResult Bacterial growth was found in 45 (33.1%) of the 136 samples tested. A total of 56rnbacterial pathogens were recovered from all specimens processed during the study. Grampositivernrnbacteria accounted for 16 (28.6%), while Gram-negative bacteria accounted for 40rn(71.4%). Among the Gram-positive isolates, Coagulase-negative Staphylococci 13(23.2%)rnwere frequently isolated followed by Bacillus species 2(3.6%). Klebsiella species 21(37.5%)rnwere most isolated of the Gram-negative rods. The range of resistance for Gram-positive andrnGram-negative bacteria were from 87.5% – 100% and 30% – 100% respectively. From thernstudy participants, 32(82.1%) clean surfaces of medical equipment and inanimate, and 33rn(84.6%) cleaned the reusable equipment before storage or used on next patient.rnConclusion: In the ICU, the rate of bacterial contamination found is high and mostly resistance rnto different types of anti-microbial drugs were prescribed. The infection control and prevention rnunit in the hospital is better to adopt observation on a regular basis.
