Computer-aided mammography: a case study of coping with fallibility in a skilled decision-making task.

Breast screening requires radiologists to exercise keen perceptual skills to find what may be faint, small features, and sophisticated interpretative skills to classify them correctly. Understandably, radiologists sometimes make errors, and evidence suggests that employing a computer prompting aid can reduce them. To investigate prompting aid requirements, we have studied both current reading practices and radiologists reading with prompts. These studies have enabled us to understand better how radiologists manage errors in current practice, and how they deal with prompting aid errors. They also show that such aids may get used in ways quite different from those originally envisaged.

Methodological issues in mammography double reading studies.

OBJECTIVES: An examination of the methods used in assessing cancer detection rates in double reading studies to obtain a clear interpretation of the disparate results from differing studies. SETTING: National breast screening programmes. METHODS: Critical appraisal of methodologies used in the comparison of cancer detection rates with single or double reading. RESULTS: The reported improvement in cancer detection rate with double reading varies greatly between studies, depending upon whether the study is blinded and the statistic used. A method of calculating the increase in cancer detection rate due to a second reader is proposed.
