Abstract

As more local governments adopt mammography for breast cancer screening, the shortage of qualified doctors skilled in interpreting mammograms must be resolved. In the interest of promoting skilled mammogram interpretation, the Central Committee for Quality Control of Mammographic Screening initiated examinations in mammogram interpretation (“exams” hereafter). Three exams were given before October 2001 to the attendants of the mammogram training courses (“training courses”) with the objective of upgrading prior exam grades. In order to assess the quality of the exams as given at the training courses, questionnaires were distributed after the exams. A total of 332 doctors took the 3 exams. Among them, 26 doctors (8%) obtained grade A, 161 (48%) obtained grade B, 93 (28%) grade C, and 52 (16%) grade D. Among the 100 (30%) who improved to at least grade B (qualified to interpret mammograms) were 26 (8%) who were upgraded to grade A and 74 (22%) who were upgraded to grade B. Unfortunately, 65 (20%) demonstrated a poorer performance, falling from grade B to grade C/D. The percentage of doctors who had experience reading fewer than 100 mammograms was 48%among those who downgraded, and 33% among those upgraded. Answers to questionnaires indicate that interpreting as many mammograms as possible is advisable in order to improve daily proficiency, exam performance, and patient care. Questionnaires at the exams seemed to aid in quality control.
