Assessment of the knowledge, awareness, and practice (KAP) of diagnostic reference levels (DRLs) among radiologists...

Dose optimization in radiation-based imaging is pivotal in enhancing patient safety and minimizing unnecessary exposure. DRLs are useful guides in dose management in clinical settings. This study assesses the level of awareness, practices, and barriers of DRLs among radiological professionals in the UAE, trying to highlight the main issues affecting their involvement.

To meet the aims of the study, a cross-sectional survey was conducted among 101 radiology professionals, using an online questionnaire. Demographic data and assessment of the knowledge, practice behaviors, awareness, and perceived barriers of DRLs were collected. Descriptive statistics and nonparametric tests, including the Mann-Whitney U and Kruskal-Wallis H tests, were performed for differences in demographic groups.

Participants demonstrated a high level of DRL knowledge (mean score: 73.4 ± 14.29), and most routinely applied dose-optimization techniques (87.1%). Awareness was more variable: although 88.1% reported familiarity with DRL guidelines, 33.6% mistakenly believed DRLs were legally binding. Key barriers included limited institutional audits (28.7%), insufficient training, and uncertainty regarding national regulatory responsibilities. Significant differences in practice and awareness were associated with age and qualification (p < 0.001), with more experienced and highly qualified professionals showing greater engagement with DRL principles.

The findings highlight strong foundational knowledge and positive practice patterns but reveal gaps in awareness and institutional support for DRL implementation. Targeted educational initiatives, structured professional development, and strengthened institutional policies are needed to improve DRL understanding and promote consistent, effective dose-optimization practices within the surveyed cohorts and similar clinical settings.

Medical scans that use radiation need careful dose control to keep people safe. This study asked radiology staff about their use and understanding of dose guidelines that help manage radiation levels. This study found that most had good knowledge and used dose reduction methods, but some lacked clear understanding and support. This matters because better training and guidance can help ensure safer scans for patients.
