Structured reporting of x-rays for atraumatic shoulder pain: advantages over free text?

BACKGROUND: To analyse structured and free text reports of shoulder X-ray examinations evaluating the quality of reports and potential contributions to clinical decision-making. METHODS: We acquired both standard free text and structured reports of 31 patients with a painful shoulder without history of previous trauma who received X-ray exams. A template was created for the structured report based on the template ID 0000154 (Shoulder X-ray) from radreport.org using online software with clickable decision trees with concomitant generation of structured semantic reports. All reports were evaluated regarding overall quality and key features: content, information extraction and clinical relevance. RESULTS: Two experienced orthopaedic surgeons reviewed and rated structured and free text reports of 31 patients independently. The structured reports achieved significantly higher median ratings in all key features evaluated (P < 0.001), including facilitation of information extraction (P < 0.001) and better contribution to subsequent clinical decision-making (P < 0.001). The overall quality of structured reports was significantly higher than in free text report (P < 0.001). CONCLUSIONS: A comprehensive structured template may be a useful tool to assist in clinical decision-making and is, thus, recommended for the reporting of degenerative changes regarding X-ray examinations of the shoulder.

Effect of endoleaks on changes in aortoiliac volume after endovascular repair for abdominal aortic aneurysm.

PURPOSE: To evaluate changes in aortoiliac volume after endovascular repair (EVAR) for abdominal aortic aneurysm (AAA) in patients with and without endoleaks. MATERIALS AND METHODS: We retrospectively analyzed 137 patients who underwent EVAR for AAA. We manually measured the aortoiliac volume on pre-procedural baseline CT angiograms (CTAs) and post-procedural follow-up CTAs. All post-procedural CTAs were evaluated for the presence of endoleaks. Follow-up examinations were grouped into five time points relative to the date of the EVAR procedure and mean aortoiliac volume changes from the baseline were calculated. RESULTS: In 51 patients (37.2%), endoleaks were detected during follow-up. In patients without any endoleaks, mean aortoiliac volume decreased by 21.1% from the pre-interventional baseline examination to the last follow-up examination. In patients with any endoleak during follow-up aortoiliac volume increased by 12.2% and in patients with only transient, post-procedural endoleaks (n = 18), aortoiliac volume decreased by 13.4% over the same time period. CONCLUSION: After EVAR for AAA, aortoiliac volume on CT angiography decreases by approximately 20% over time in the absence of endoleaks and increases in the presence of endoleaks. Transient post-procedural endoleaks, however, do not influence long-term volume regression.
