Intra- and interobserver variation in lung sound classification. Effect of training.
This study explores how last year medical students at the University of Tromsø, the Arctic University of Norway, interpret and describe different lung sounds. This is done by measuring intra- and interobserver variation in agreement among 16 students, when reporting abnormal lung sounds after listen...

This study explores how last year medical students at the University of Tromsø, the Arctic University of Norway, interpret and describe different lung sounds. This is done by measuring intra- and interobserver variation in agreement among 16 students, when reporting abnormal lung sounds after listening to audio recordings. Agreement with a reference standard is included, and testing of effect on training on these agreements. To test the training effect the students were separated in two groups, one of them having an intervention, a 3 hour course. The results serves to inform the medical society about the inconsistency in reporting lung sounds in this particular population, and hopefully also help finding measures to obtain better agreement. Cohens kappa have been used to measure intraobserver agreement and agreement with the reference standard, Fleiss kappa to measure interobserver agreement. An “exact” Mann-Whitney U test for testing the effect of the course. The kappa level of agreement set to define acceptable agreement is “moderate”, with a lower limit of .41. The results indicate highly acceptable intraobserver agreement, and the agreement tended to improve in both the intervention and the control group.
