A direct survey was taken of 1,238 members of the Society of Cardiovascular and Interventional Radiology (SCVIR) concerning the routine use of 14 tests (most frequently, prothrombin and partial thromboplastin times, complete blood cell counts, and blood urea nitrogen and serum creatinine levels) performed before 10 invasive percutaneous procedures (peripheral angiography, neuroangiography, transluminal angioplasty, thrombolysis, percutaneous needle biopsy, abscess drainage, percutaneous nephrostomy, biliary drainage, myelography, and venography). The survey was undertaken to determine the current practices and appropriateness of current routine use of preprocedural tests. The response rate was 34%, representing a cumulative annual volume of 322,208 cases. The practice of performing routine preprocedural tests is common among interventional radiologists. Data provided by this survey suggest that use of these tests is excessive. Adherence to suggested proposals derived from previously reported experience would result in an annual estimated savings of $20.0-$34.9 million (extrapolated for all procedures performed by SCVIR members in 1989).
对心血管与介入放射学会（SCVIR）的1238名成员进行了一项直接调查，内容涉及在10种侵入性经皮操作（外周血管造影、神经血管造影、腔内血管成形术、溶栓、经皮针刺活检、脓肿引流、经皮肾造瘘术、胆道引流、脊髓造影和静脉造影）之前进行的14项检查（最常见的是凝血酶原时间和部分凝血活酶时间、全血细胞计数以及血尿素氮和血清肌酐水平）的常规使用情况。进行这项调查是为了确定当前的做法以及当前术前检查常规使用的合理性。回复率为34%，代表着每年累计病例数为322,208例。在介入放射科医生中，进行常规术前检查的做法很常见。本次调查提供的数据表明这些检查的使用过度。遵循根据先前报告的经验得出的建议方案，估计每年可节省2000万至3490万美元（根据SCVIR成员在1989年进行的所有操作进行推算）。
