Worldwide Knowledge About Interventional Radiology Among Medical Students: Findings of a Comprehensive Review

PURPOSE

The objective of this comprehensive review is to investigate the studies assessing the interventional radiology knowledge among medical students worldwide and inspect the feasible solutions for improving their perspective on this specialty.

METHODS

A comprehensive literature search was accomplished on PubMed, Scopus, Web of science, and Embase databases. The quality of eligible articles was assessed with the QATSDD assessment tool.

RESULTS

After screening of articles, 29 studies were included. All the included articles were published between 2009 and 2021, with 20 studies performed in 2017 and thereafter. Interventional radiologists' duties, procedures, and training pathways were the main subjects investigated in surveys. The interest and exposure to interventional radiology were also assessed. All the studies indicated that the knowledge about interventional radiology compared with other specialties is weak. In 14 studies, over 50% of participants reported their interventional radiology knowledge as either poor or none. The most reason for not considering interventional radiology residency was lack of awareness during medical schools. Studies which held a tutorial course reported the students' awareness and interest improved significantly after the course.

CONCLUSION

The present evidence indicates that although the current awareness of interventional radiology is low, timely didactic courses in medical schools can improve this condition significantly, lead to graduation of more oriented referring physicians, and also attract more fit applicants to interventional radiology residency programs.

Diagnostic Accuracy of Ultrasonography for Detection of Intussusception in Children; a Systematic Review and Meta-Analysis

Introduction

The diagnosis of intussusception can be challenging in children due to the fact that the findings of clinical evaluations are nonspecific and most of the patients present with unclear history. Therefore, in this systematic review and meta-analysis, we aimed to investigate the diagnostic accuracy of ultrasonography for detection of intussusception and also compare the efficacy of point-of-care ultrasound (POCUS) with radiologist-performed ultrasound (RADUS).

Methods

Two independent reviewers systematically searched different online electronic databases including MEDLINE, Scopus, Web of Science, Google Scholar, Embase, and Cochrane from inception to December 1, 2022 to identify published papers reporting accuracy of ultrasonography for diagnosis of intussusception. The quality assessment of the included studies was investigated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool.

Results

A total of 1446 records were retrieved in the initial search of databases. After screening the titles, a total of 344 studies were retrieved for the detailed assessment of full-text. Finally, 37 studies were included in qualitative and quantitative analysis. The pooled sensitivity and specificity of ultrasonography for diagnosis of intussusception were 0.96 (95% CI: 0.95-0.97) and 0.97 (95% CI: 0.97-0.98), respectively. The pooled positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 24.57 (95% CI: 8.26-73.03) and 0.05 (95% CI: 0.04-0.08), respectively. The area under the hierarchical summary receiver operating characteristic (HSROC) curve was 0.989. Mete-regression showed that there is no significant difference between diagnostic performance of POCUS and RADUS (p = 0.06 and rDOR (diagnostic odds ratio) = 4.38 (95% CI: 0.92-20.89)).

Conclusion

This meta-analysis shows that ultrasonography has excellent sensitivity, specificity, and accuracy for diagnosis of intussusception in pediatric patients. Moreover, we found that diagnostic performance of POCUS is similar to that of RADUS for diagnosis of intussusception.
