A laboratory study on the reliability estimations of the mini-CEX.
Reliability estimations of workplace-based assessments with the mini-CEX are typically based on real-life data. Estimations are based on the assumption of local independence: the object of the measurement should not be influenced by the measurement itself and samples should be completely independent. This is difficult to achieve. ⋯ Generalizability coefficients indicated that an approximate sample of 9 encounters was needed assuming a single different assessor per encounter and assuming different cases per encounter (the usual situation in real practice), 4 encounters when 2 raters were used and 3 encounters when 3 raters are used. Unexplained general error and the leniency/stringency of assessors are the major causes for unreliability in mini-CEX. To optimize reliability rater training might have an effect.

Podcasting in medical education: can we turn this toy into an effective learning tool?
Advances in information technology have changed how we deliver medical education, sometimes for the better, sometimes not. Technologies that were designed for purposes other than education, such as podcasting, are now frequently used in medical education. In this article, the authors discuss the pros and cons of adapting existing technologies for medical education, caution against limiting evaluation of technologies to the level of rater satisfaction, and suggest a research agenda for formally evaluating the role of existing and future technologies in medical education.
