Knowledge of Infection Control in Ultrasound Examination: A Cross-sectional Survey Study among Sudanese Sonographic Specialists

Abstract

Background: Ultrasonography is one of the imaging modalities associated with the risk of healthcare-associated infection. Therefore, ultrasound specialists must maintain infection control standards and adherence to ultrasound infection control guidelines. Methods and Results: A cross-sectional survey was conducted through an online questionnaire to assess the knowledge of Sudanese sonographic specialists on infection control in ultrasonography. Participants who agreed to participate and complete the survey numbered 110. The result of the study demonstrate that the knowledge of infection control guidelines was average (26.93±3.79) among Sudanese sonographic specialists; the mean score of knowledge was 4.52±1.12 (moderate level), 12.51±1.96 (moderate level), 5.70±2.02 (low level), and 4.63±1.10 (average level) for ultrasound equipment, probe, gel bottles, and personal infection control precautions, respectively. Of the study participants, 70% knew that endovaginal and endocavitory probes were decontaminated by liquid chemical sterilant after each use, and 78.18% reported that the HLD was used for cleaning and disinfecting equipment in contact with mucous membranes. In addition, 91.82% of participants agreed that sterile gel is highly recommended for intervention procedures, and 89.09% were aware of proper respiratory hygiene and coughing protocol. 41.82% of respondents were aware that personal protective equipment (PPE) is advised for cleaning and sanitizing ultrasonic equipment, and only 31.82% believed that non-sterile gel is insufficient if the transducer is in contact with non-intact skin. Conclusion: The knowledge of infection control in ultrasound is average among Sudanese sonographic specialists, with a poor understanding of some ultrasound-gel infection control guidelines and safety aspects.
