To determine the cost savings of stereotactic core needle biopsy over open surgical biopsy in patient subgroups defined according to mammographic findings.
From July 1992 through February 1995, stereotactic core needle biopsy was performed in 356 women with 405 nonpalpable breast lesions (254 were masses and 151 were calcification). Lesions were classified according to mammographic finding, size, and level of suspicion. Two hundred three lesions were classified as indeterminate, 166 as suspicious, and 36 as highly suspicious. Medicare reimbursements for 1995 were used to determine costs and cost savings.
Overall cost savings for stereotactic core biopsy over open surgical biopsy was $741 per case. Average cost savings per case was $807 for masses and $630 for calcifications. The greatest savings occurred in the cases of indeterminate masses, with an average of $856 saved per case. The least savings occurred in the cases of highly suspicious calcifications, with $446 saved per case.
Cost savings of stereotactic core needle biopsy vary in subgroups of patients defined according to mammographic findings. Over-all savings will depend on the distribution of patients among these groups. In this series, cost savings were realized with stereotactic core biopsy over open surgical biopsy for all mammographic subgroups.
确定在根据乳腺钼靶检查结果定义的患者亚组中，立体定向芯针活检相对于开放手术活检的成本节约情况。
1992年7月至1995年2月，对356名患有405个不可触及乳腺病变的女性进行了立体定向芯针活检（254个为肿块，151个为钙化）。根据乳腺钼靶检查结果、大小和可疑程度对病变进行分类。203个病变被分类为不确定，166个为可疑，36个为高度可疑。使用1995年医疗保险报销数据来确定成本和成本节约情况。
立体定向芯针活检相对于开放手术活检的总体成本节约为每例741美元。肿块每例平均成本节约为807美元，钙化为630美元。不确定肿块病例的节约最多，每例平均节约856美元。高度可疑钙化病例的节约最少，每例节约446美元。
立体定向芯针活检的成本节约在根据乳腺钼靶检查结果定义的患者亚组中有所不同。总体节约将取决于患者在这些组中的分布情况。在本系列中，对于所有乳腺钼靶亚组，立体定向芯针活检相对于开放手术活检均实现了成本节约。
