All physicians who had billed Pennsylvania Blue Shield for at least three intravenous contrast studies during 1989 were surveyed on their use of nonionic versus ionic contrast. This surveyed group represents a diversity of hospital sizes, practice types, and group sizes. Of the 383 physician groups surveyed, responses were obtained from 285. The majority of the responding groups were radiologists (94.0%). Nonionic contrast is utilized in 41.3% of all intravenous studies. Radiologists use nonionic contrast in a much greater proportion than nonradiologists (P < 0.0001), with 17.6% of radiologists utilizing nonionic contrast in all of their patients. Conversely, 75% of nonradiologists utilize ionic contrast in all of their patients. For all physician groups surveyed, 40.3% utilize nonionic for at least 50%, while 27.6% use nonionics for more than 75% of their patients. The routine use of steroid premedication prior to the injection of ionic contrast is not a common practice. The increased utilization of nonionic contrast found in this survey may reflect the cross-section of physicians and practice types surveyed or may represent changing practice patterns among physicians utilizing contrast material.
对1989年期间至少为宾夕法尼亚蓝盾保险公司开具过三项静脉造影检查账单的所有医生进行了关于其使用非离子型造影剂与离子型造影剂情况的调查。这个被调查群体代表了不同规模的医院、不同类型的医疗业务以及不同规模的医疗团队。在接受调查的383个医生团队中，收到了285个团队的回复。回复的团队中大多数是放射科医生（94.0%）。在所有静脉造影检查中，41.3%使用了非离子型造影剂。放射科医生使用非离子型造影剂的比例远高于非放射科医生（P < 0.0001），17.6%的放射科医生在其所有患者中都使用非离子型造影剂。相反，75%的非放射科医生在其所有患者中都使用离子型造影剂。对于所有接受调查的医生团队，40.3%的团队至少50%的情况下使用非离子型造影剂，而27.6%的团队在超过75%的患者中使用非离子型造影剂。在注射离子型造影剂前常规使用类固醇进行预处理并不常见。本次调查中发现的非离子型造影剂使用增加情况，可能反映了所调查医生和医疗业务类型的横断面情况，也可能代表了使用造影剂的医生中不断变化的医疗实践模式。
