| dc.description.abstract | Background: As a result of the large influx of patients into the medical imaging department, the surfaces of equipment could represent a reservoir for pathological agents and source of transmission of infections to patients and healthcare professionals. Objective: To assess Bacterial contamination level of radiological equipments and factors affecting disinfection among radiology health professionals at 12 public health hospitals, Addis Ababa Ethiopia. Methods: A total of 178 swab samples collected from radiological equipments of X-ray, Ultrasound, Computed tomography, and Magnetic resonance Image equipments were selected and assessed for microbiological contamination in selected public hospitals of Addis Ababa. Self-administered structured questionnaire was used to collect factors affecting disinfection process among 137 medical radiology health professionals. The collected specimen was inoculated on (Blood agar and MacConkey agar) and incubated at 35-37±0.5°C for 24 hours. The suspected colonies were further subjected to gram’s staining and biochemical test was performed for gram positive and negative isolates. A standard disc diffusion technique for antimicrobial susceptibility test (AST) test was performed for all the isolates using CLSI (Clinical laboratory standard institute 2017). SPSS version 24 used to analyze the data. Bacterial isolates which are resistant to two or more classes of drugs were considered as multidrug resistant (MDR). Results: Out of 178 swab samples, we found 151(84.8%) bacterial isolates from all radiological equipments. High bacteria contamination rate were found on X-RAY machines accounts for 75(49.7%) and Gram-positive organisms were the most frequently isolated bacteria. particularly, Coagulase negativestaphylococci (CoNS) accounts 98(55.1%). Pseudomonas aeruginosa was the most isolated Gram-negative bacteria and accounts 7(3.9%). Methicilin resistant Staphylocoous aureus (MRSA) were found 5 of 12 (41.6%) of S. aureus isolates. Conclusion: This research showed high bacterial contamination rate of radiological equipments and isolates shows high resistance rate for different antimicrobial drugs. And there are factors affecting decontamination of radiological equipments. Hence, awareness for these factors should be raised among radiology health professionals. | en_US |
