title: The role of experience in clinical accuracy.
abstract: A randomized controlled trial was performed to study the effect of various teaching techniques on students performing sacroiliac motion palpation tests. This trial assessed the interexaminer reliability of interns in their final year at a chiropractic college, and compared their results prior to and following 1 year of clinical experience. The study also compared the intra- and interexaminer reliability of experienced clinicians. The results were analyzed via the Kappa coefficient. Kappa values for interns ranged from 0.00 to 0.30, with no significant differences noted at the end of 1 year of clinical experience. The interexaminer reliability of experienced clinicians was 0.00 to 0.167, whereas their intraexaminer reliability ranged from 0.15 to 1.00. These results question the role of experience in improving clinical accuracy between examiners performing sacroiliac motion palpation. Results analyzed for intraexaminer agreement were moderate to almost perfect. We conclude that experience does not play a significant role in the diagnostic test analyzed, but rather that clinicians may establish their own criteria by which to determine the standards of a given test.
