在肌骨影像学检查中优先使用超声的价值
临床证据和研究在不断支持用超声作为优先诊断工具对各种肌骨(MSK)疾病进行检查。诊断超声提供了很多计算机断层扫描(CT)和磁共振成像(MRI)无法比拟的安全性和有效性上的优势。诊断超声是一种无创式实时成像方法,从而使在静态和动态下的结构检查成为可能。这一捕捉肌骨运动的功能,使超声区别于其他影像设备,从而使更精确的检查成为可能。其他给患者带来的优点包括:便携性,它可以帮助实现Point-of-Care应用和诊断。
然而,由于各种原因,医疗保健服务的提供者已经被逐渐引向更昂贵的成像诊断方法。而使用诸如CT或MRI,而不是成本效率更高的超声,可能会提供更好的结果,但与此同时也增加整个医疗系统的成本和病人的成本。
A Cost-Effective, Lower-Risk Approach
仅2009年,CT和MRI占Medicare认可的四肢影像检查的95%。仅有5%是成本效率更高,避免辐射风险的超声检查。使用成本更低更安全的影像检查在获取临床信息的同时,并不会影响对病人关护的质量。一篇由Parker等学者发表于2008年的论文指出,从2006年到2020年,如果对于合适的病例,用超声MSK检查替代MRI MSK检查,可以为Medicare预计节省超过69亿美元的医疗支出。1

一份由KNG Health Consulting, LLC2进行的研究显示,如果超声被首先作为诊断工具,将实现全美医疗机构和患者的成本降低。KNG 2009Medicare数据显示如果使用超声替代30%的MRI或CT肩袖损伤检查,将降低超过3100万美元成本。如果替代30%的MRI或CT踝关节检查,则降低成本约800万美元。而如果超声检查被用于替代70%的MRI或CT上述两项检查,总计成本节省将超过9100万美元。
What our customers say
"Point-of-care ultrasound is a perfect tool for screening patients with shoulder and elbow problems in the primary diagnostic setting. A torn tendon in the shoulder can be diagnosed easily, no matter which tendon is affected." Read More
