Objectives To investigate the utilisation, reliability and validity of clinical evaluation exercise (CEX) in otolaryngology training.
Design Retrospective database analysis.
Setting Online assessment database.
Participants We analysed all CEXs submitted by north London core (CT) and speciality trainees (ST) in otolaryngology from 2010 to 2013.
Main Outcome Measures Internal consistency of the 7 CEX items rated as either O: outstanding, S: satisfactory or D: development required. Overall performance rating (pS) of 1-4 assessed against completion of training level. Receiver operating characteristic was used to describe CEX sensitivity and specificity. Overall score (cS), pS and the number of D'-rated items were used to investigate construct validity.
Results One thousand one hundred and sixty CEXs from 45 trainees were included. CEX showed good internal consistency (Cronbach's alpha= 0.85). CEX was highly sensitive (99%), yet not specific (6%). cS and pS for ST was higher than CT (99.1%0.4 versus 96.6%+/- 0.8 and 3.06 +/- 0.05 versus 1.92 +/- 0.04, respectively P<0.001). pS showed a significant stepwise increase from CT1 to ST6 (P<0.001). In contrast, cS only showed improvement up to ST4 (P=0.025). The most frequently utilised item management and follow-up planning' was found to be the best predictor of cS and pS (r(s)=+0.69 and +0.21, respectively).
Conclusion CEX is reliable in assessing early years otolaryngology trainees in clinical examination, but not at higher level. It has the potential to be used in a summative capacity in selecting trainees for ST positions. This would also encourage trainees to master all domains of otolaryngology clinical examination by end of CT.
