    Abstract

    Objectives: To investigate the levels of agreement between expert respiratory physicians when making a diagnosis of occupational asthma. Methods: 19 cases of possible occupational asthma were identified as part of a larger national observational cohort. A case summary for each case was then circulated to 12 physicians, asking for a percentage likelihood, from the supplied information, that this case represented occupational asthma. The resulting probabilities were then compared between physicians using Spearman's rank correlation and Cohen's K coefficients. Results: Agreement between the 12 physicians for all 19 cases was generally good as assessed by Spearman's rank correlation. For all 66 physician-physician interactions, 45 were found to correlate significantly at the 5% level. The agreement assessed by K analysis was more variable, with a median κ value of 0.26, (range -0.2 to +0.76), although 7 of the physicians agreed significantly (p
