The initial examination for a Certificate of Added Qualifications in Surgery of the Hand
JR Urbaniak, GE Cruft and TW Biester
American Board of Orthopaedic Surgery, Chicago, Illinois 60611.
A total of 510 candidates took the 1989 Examination for Added
Qualifications in Surgery of the Hand, including 412 diplomates of the
American Board of Orthopaedic Surgery and ninety-eight diplomates of the
American Board of Surgery. Most candidates reported that they had intensive
practices in hand surgery and large annual case-loads, and most had taken a
hand fellowship. However, there were significant differences between
diplomates of the American Board of Orthopaedic Surgery and diplomates of
the American Board of Surgery regarding these variables. The psychometric
characteristics of the examination were very good. The average difficulty
value was 77.6 per cent correct. The average item-discrimination value was
high, and the total test reliability coefficient was 0.89. In general, the
candidates' performance was very good, although there was a wide range in
scores. A passing score of 66.3 per cent correct was selected, resulting in
an over-all failure rate of 7.6 per cent, with 471 candidates passing and
thirty-nine failing the examination. There were significant relationships
between performance on the examination and several background variables,
such as percentage of practice in hand surgery, having taken a hand
fellowship, and size of the annual case-load.
