Accuracy of junior doctor plain trauma X-ray interpretation: a systematic review and meta-analysis
Abstract
BACKGROUND: Plain radiography remains a first-line assessment tool for emergency departments’ trauma patients. Given the urgency of trauma care, emergency department doctors, including junior doctors, often perform initial trauma X-ray interpretations to support timely patient management when there is an unavailability of an immediate radiologist report. However, trauma X-ray interpretation is challenging, and inaccuracies can impact patient care. This study evaluates the diagnostic accuracy of emergency department junior doctors on the initial interpretation of trauma X-rays by systematically reviewing and meta-analysing existing research on the subject. METHOD: Studies were identified from PubMed, Scopus, Embase, Cochrane Library, and by checking the reference lists of relevant studies. Quality assessment of included studies was evaluated using the QUADAS-2 tool. Meta-analysis was conducted using bivariate models, with summary estimates reported as sensitivity, specificity, and the SROC. Meta-regression and subgroup analysis was performed to evaluate the sources of heterogeneity. Publication bias was assessed using Deeks’ funnel plot. RESULTS: Seven studies were included in this meta-analysis. Across the studies, pooled sensitivity, specificity and area under the receiver operating characteristic curve (AUC) were 0.65 (95% CI = 0.47–0.80), 0.89 (95% CI = 0.77–0.95), and 0.86 (95% CI = 0.83–0.89), respectively. Covariate analysis per anatomical region of trauma X-rays…
