To describe the extent to which screening mammography (SCM) has been organized according to the public health concept of low-cost, high-quality, and population-based screening, selected indicators of U.S. mammography facilities were evaluated.
Data from the National Cancer Institute's phase I of the National Survey of Mammography Facilities were analyzed. This data base consists of questionnaire information obtained in 1992 from a 10% random sample of U.S. mammography facilities.
Of 1,057 facilities, 634 (60%) distinguished SCM from diagnostic mammography (DXM). In facilities providing SCM (n = 535), 477 (89%) used the mediolateral oblique (MLO) view and/or the craniocaudal (CC) view. While 898 (85%) of all facilities requested clinical follow-up of abnormal mammograms, only 285 (27%) facilities actually received this information. Only 137 (13%) facilities operated at high volume (> or = 15 mammograms per day per machine), and 211 (20%) used batch interpretation. Average cost of a screening mammogram was $89 (range, $10-$225).
While more facilities are distinguishing SCM from DXM and obtain MLO and CC views, SCM does not appear to be organized for high volume and low cost.
为描述乳腺筛查钼靶（SCM）在多大程度上按照低成本、高质量和基于人群筛查的公共卫生理念进行组织，对美国乳腺钼靶检查设施的选定指标进行了评估。
分析了美国国立癌症研究所乳腺钼靶检查设施全国调查第一阶段的数据。该数据库包含1992年从美国10%的乳腺钼靶检查设施随机样本中获得的问卷信息。
在1057家设施中，634家（60%）区分了SCM和诊断性乳腺钼靶检查（DXM）。在提供SCM的设施（n = 535）中，477家（89%）使用了内外侧斜位（MLO）视图和/或头尾位（CC）视图。虽然所有设施中有898家（85%）要求对异常乳腺钼靶检查进行临床随访，但实际上只有285家（27%）设施收到了该信息。只有137家（13%）设施高流量运行（每台机器每天≥15次乳腺钼靶检查），211家（20%）采用批量解读。一次乳腺筛查钼靶检查的平均费用为89美元（范围为10 - 225美元）。
虽然有更多设施区分了SCM和DXM，并获取了MLO和CC视图，但SCM似乎并未针对高流量和低成本进行组织。
