PURPOSE
Mobile mammography can improve access to screening mammography in rural areas and underserved populations. We evaluated the frequency of incomplete reports in mobile mammography screening and the relationships between prior mammograms and recall rates.
METHODS
The frequency of incomplete mammogram reports, the subgroups of those needing prior comparison mammograms, recalls for additional imaging, and availability of prior mammograms of a mobile screening mammography unit were compared with fixed site mammography from January 1, 2007 through December 31, 2009. All mobile unit mammograms were full field digital mammography (FFDM). Differences between rates of recall, incomplete reports, and availability of prior mammograms were calculated using the Chi-Square statistic.
RESULTS
Of 2640 mobile mammography cases, 21.9% (578) reports were incomplete, versus 15.2% (7653) (p ≤ 0.001) of 50325 fixed site reports. Of incomplete cases, recall for additional imaging occurred among 8.3% (218) of mobile mammography reports versus 11.3% (5708) (p ≤ 0.001) of fixed site reports. Prior mammograms were needed among 13.6% (360) of mobile mammography versus 3.9% (1945) (p ≤ 0.001) of fixed site reports. Mobile mammography recall rate varied with availability of prior mammograms: 16.0% (54) when no prior mammograms, 7.6% (127) when prior mammograms were elsewhere but unavailable and 5.9% (37) when prior FFDM were immediately available (p ≤ 0.001).
CONCLUSIONS
Incomplete reports were more frequent in mobile mammography than the fixed site. The availability of prior comparison mammograms at time of interpretation decreased the rate of incomplete mammogram reports. Recall rates were higher without prior comparison mammograms and lowest when comparison FFDM mammograms were available.
目的
移动乳房 X 光摄影术可改善农村地区和服务不足人群的筛查乳房 X 光摄影术的可及性。我们评估了移动乳房 X 光摄影术筛查中不完整报告的频率，以及先前乳房 X 光检查和召回率之间的关系。
方法
比较了 2007 年 1 月 1 日至 2009 年 12 月 31 日期间移动筛查乳房 X 光摄影术单位与固定站点乳房 X 光摄影术之间不完整乳房 X 光报告的频率、需要先前比较乳房 X 光检查的亚组、额外成像的召回率以及先前乳房 X 光摄影术的可用性。所有移动单位乳房 X 光检查均为全视野数字化乳房 X 光摄影术（FFDM）。使用卡方检验计算召回率、不完整报告率和先前乳房 X 光检查可用性之间的差异。
结果
在 2640 例移动乳房 X 光摄影术病例中，21.9%（578 例）报告不完整，而 50325 例固定站点报告中，15.2%（7653 例）报告不完整（p≤0.001）。在不完整的病例中，移动乳房 X 光摄影术的额外成像召回率在 8.3%（218 例）中发生，而在固定站点报告中为 11.3%（5708 例）（p≤0.001）。在移动乳房 X 光摄影术病例中，需要先前的乳房 X 光检查，13.6%（360 例），而在固定站点报告中为 3.9%（1945 例）（p≤0.001）。移动乳房 X 光摄影术的召回率随先前乳房 X 光检查的可用性而变化：无先前乳房 X 光检查时为 16.0%（54 例），先前乳房 X 光检查在其他地方但无法获得时为 7.6%（127 例），而当立即获得先前 FFDM 时为 5.9%（37 例）（p≤0.001）。
结论
与固定站点相比，移动乳房 X 光摄影术的不完整报告更为频繁。在解释时获得先前的比较乳房 X 光检查可降低不完整乳房 X 光报告的发生率。在没有先前比较乳房 X 光检查的情况下，召回率较高，而当可获得比较 FFDM 乳房 X 光检查时，召回率最低。
