Abstract
Study hypothesis
Point-of-care ultrasound (PoCUS) can be used as a non-invasive and radiation free adjunct in the triage of patients with clavicle injuries. However, the diagnostic accuracy of PoCUS performed by non-radiologists for this purpose is not yet sufficiently established.
Methods
A multicentre, prospective cohort study was conducted in 8 emergency departments (EDs) to establish the diagnostic accuracy of PoCUS of the clavicle in patients ≥4 years of age who presented with a clavicle injury. PoCUS was performed by trained emergency physicians, and results were compared with X-ray outcomes (gold standard).
Results
A total of 167 patients were included, of which 127 (76 %) patients had a fracture on X-ray, and 121 (72 %) on PoCUS. PoCUS of the clavicle had a sensitivity of 93 % (95 %CI 87–97 %), a specificity of 93 % (95 %CI 80–98 %), a negative likelihood ratio of 0.09 (95 %CI 0.04–0.14), and a positive likelihood ratio of 12.39 (95 %CI 4.17–36.82) for the presence of a clavicle fracture. Stratified based on age, specificity of PoCUS was lower in children compared to adults, whereas sensitivity was not affected. The agreement between X-ray and PoCUS for fracture displacement was substantial (κ = 0.771).
Conclusions
PoCUS of the clavicle is a useful adjunct in the triage of patients with clavicle injuries and can help to distinguish which patients need further diagnostic workup.
研究假设:即时超声(PoCUS)可作为一种无创、无辐射的辅助手段用于锁骨损伤患者的分诊。然而,由非放射科医师进行PoCUS诊断的准确性尚未充分确定。方法:在8个急诊科(EDs)进行了一项多中心、前瞻性队列研究,以确定4岁以上锁骨损伤患者锁骨PoCUS的诊断准确性。PoCUS由训练有素的急诊医生进行,并将结果与x线结果(金标准)进行比较。结果:共纳入167例患者,其中x线骨折127例(76%),PoCUS骨折121例(72%)。锁骨PoCUS对锁骨骨折的敏感性为93% (95% CI 87- 97%),特异性为93% (95% CI 80- 98%),阴性似然比为0.09 (95% CI 0.04-0.14),阳性似然比为12.39 (95% CI 4.17-36.82)。根据年龄分层,儿童PoCUS的特异性比成人低,而敏感性不受影响。x线与PoCUS对骨折位移的诊断结果一致(κ = 0.771)。结论:锁骨PoCUS在锁骨损伤患者的分类中是一个有用的辅助手段,可以帮助区分哪些患者需要进一步的诊断检查。试验注册号:荷兰试验登记,注册代码:NL9236。
