    Background: Reports indicated that numerous factors, including inadequate personnel knowledge, contributes to insufficient patient data for setting up diagnostic reference levels (DRLs) in developing countries. This study aims to evaluate the knowledge of DRLs as an optimisation tool amongst computed tomography (CT) radiographers in northern Nigeria. This is a quantitative cross-sectional study. A structured questionnaire was devised and distributed on site to sixty-two CT radiographers in northern Nigeria. A total of fifteen questions were included in the questionnaire focusing on DRLs, dose optimisation and dose descriptors generating quantitative data concerning overall CT radiographers’ perceived knowledge and awareness about DRLs. Results: A response rate of 77.4% (48/62) was achieved. About 83.3% of the participants declare DRLs awareness, and 37.5% carried out a local dose survey. The percentage correctly perceived knowledge of concepts; DRLs was 45.8%, dose optimisation (42%) and CT dose descriptor (39%). Radiographers with work experience ranging from 4- 10 years had the highest score. Conclusion: In this survey, deficiencies were noted in radiographers’ knowledge about DRLs with precise knowledge gap in the implementation of local dose survey for DRLs and optimisation. There is a need for continuous radiographers’ training with greater emphasis on dose optimisation and institutional based dose evaluation.

    Awareness and Perception of Novel Omicron Variant (B. 1. 1.529) Among Radiographers in Northern Nigeria

    Background: The advent of the novel Omicron COVID-19 variant is expected to alter radiographers’ standard of practice due to its rapid transmission capability. This study aimed to assess the radiographers’ awareness and perception of the Omicron among radiographers in Northern Nigeria. Methods: A cross-sectional online survey was carried out among radiographers in Northern Nigeria using convenience sampling techniques. The survey tool was designed using Google consisting of questions on the demographics, general awareness, and perception about the Omicron. The questionnaire was face-validated, and the reliability was tested using Cronbach alpha. A coefficient of 0.7 was obtained which is considered adequate. Descriptive statistics and Chi-square test at 0.05 level of significance were used to analyse the data using Microsoft Excel 2016 (Microsoft Inc, Redmond, WA). Results: A total of 186 radiographers participated in the survey. The respondents demonstrated a ‘’Good’’ awareness level with an average score of 4.3/6 (70%). The perception was generally good as about half (n=91; 48.9%) of the respondents agreed with six out of eight perception-based determinants. Only a minority (n=77; 41%) of the respondents were not certain whether the Omicron spreads faster compared to other COVID-19 variants. A similar number (n=76; 40%) of the respondents were doubtful whether COVID-19 vaccine booster dose could help in curtailing the Omicron. Conclusion: The level of awareness and perception of the Omicron among the radiographers was generally “Good”. Notwithstanding, the radiographers were doubtful about the speed of the transmission of the Omicron and whether booster vaccination could help reduce the transmission. Implication for practice: To mitigate occupational exposure to the novel Omicron COVID-19 variant amongst radiographers, urgent institutional strategies should be put in place to promote their knowledge and awareness of novel infectious diseases to keep up with the standard practice.
