Effectiveness and cost-effectiveness of double reading of mammograms in breast cancer screening: findings of a systematic review

摘要: There is a lack of direct evidence on the effectiveness double reading breast screening mammograms within context national programmes even though about half countries that use mammography have implemented reading. A systematic review was conducted to compare with single for accuracy, patient outcomes and costs. We searched an extensive range electronic databases, bibliographies studies were scanned experts contacted. Data extraction quality assessment undertaken independently by two reviewers. Estimates diagnostic accuracy calculated those follow-up identify interval cancers. Only 10 cohort met inclusion criteria reported extractable data compared The mix methodologies meant few conclusions could be drawn effect independent number views, or effects size type tumours detected. Overall, increases cancer detection rate 3-11 per 10,000 women screened has impact recall rates depending policy used. benefit mainly in small cancers, greatest where readers different strengths weaknesses, are less experienced. Double can improve as In particular, consensus arbitration achieves increase together reduction recalled assessment. Further research should quantify relative from according mammographic estimate outcome.
