To assess subspecialty mix and case volumes of general and abdominal subspecialty radiologists interpreting abdominal MRI.
The 2016 CMS Physician/Supplier Procedure Summary Master File was used to obtain billed counts of radiologist-interpreted abdominal fluoroscopy, US, CT, and MRI examinations. The CMS Physician and Other Supplier Public Use File was used to assess the subspecialty mix and case volume of the radiologists interpreting those examinations.
The fraction of all abdominal imaging examinations interpreted by generalists and abdominal subspecialty radiologists was 70.7% and 16.5% for fluoroscopy; 68.7% and 21.0% for US; 71.4% and 19.2% for CT; and 41.9% and 52.5% for MRI. In 2016, the fraction of general and abdominal radiologists interpreting > 50 fluoroscopy examinations on Medicare fee-for-service beneficiaries was 15.1% and 16.2%. For > 50 US examinations, the fraction was 61.5% and 60.5%; for > 50 CT examinations, 91.2% and 79.6%; and for > 50 MRI examinations, 4.0% and 28.5%. The fraction of abdominal imaging examinations interpreted overall by low-volume providers (those interpreting ≤ 50 examinations in 2016) was 59.5% for fluoroscopy, 17.5% for US, 6.3% for CT, and 50.6% for MRI.
Nationally, most abdominal fluoroscopy, US, and CT examinations are interpreted by general radiologists, who have similar annual volumes of these examinations as abdominal subspecialty radiologists. In contrast, most abdominal MRI examinations are interpreted by abdominal subspecialty radiologists, who attain considerably higher volumes. These findings have implications for workforce planning and abdominal imaging fellowship design to ensure their graduates are optimally prepared to contribute to their future practices.
评估解读腹部磁共振成像的普通放射科医生和腹部放射科医生的亚专业组合和病例量。
使用 2016 年 CMS 医师/供应商程序摘要主文件获取放射科医生解读腹部荧光透视、超声、CT 和 MRI 检查的计费次数。使用 CMS 医师和其他供应商公共使用文件评估解读这些检查的放射科医生的亚专业组合和病例量。
普通放射科医生和腹部放射科医生解读所有腹部影像学检查的比例为：荧光透视 70.7%和 16.5%；超声 68.7%和 21.0%；CT 71.4%和 19.2%；MRI 41.9%和 52.5%。2016 年，在 Medicare 按服务收费的受益人中，解读 > 50 次荧光透视检查的普通放射科医生和腹部放射科医生的比例分别为 15.1%和 16.2%。对于 > 50 次超声检查，这一比例分别为 61.5%和 60.5%；对于 > 50 次 CT 检查，这一比例分别为 91.2%和 79.6%；对于 > 50 次 MRI 检查，这一比例分别为 4.0%和 28.5%。2016 年解读量 ≤ 50 次的低容量提供者（解读量 ≤ 50 次的提供者）总体上解读腹部影像学检查的比例为：荧光透视 59.5%，超声 17.5%，CT 6.3%，MRI 50.6%。
在全国范围内，大多数腹部荧光透视、超声和 CT 检查由普通放射科医生解读，他们的这些检查的年度工作量与腹部放射科医生相似。相比之下，大多数腹部 MRI 检查由腹部放射科医生解读，他们的工作量要高得多。这些发现对劳动力规划和腹部影像学奖学金设计具有影响，以确保他们的毕业生为未来的实践做好最佳准备。
