Abstract

Introduction: Auscultation, an essential component of physical assessment, has been the subject of debate due to the poor concordance observed between different assessors.

Objective: To evaluate the concordance of lung sound recording discrimination among physicians in Ecuador.

Methods: Inter-rater agreement was determined using Fleiss' Kappa statistic. This was a cross-sectional, observational, analytical and prospective study. The study population consisted of 10 physicians belonging to the staff of the Intensive Care Unit of a hospital located in the city of Ecuador. Ten recordings were played for subject recognition using a laptop at their workplace. The results were analyzed using Fleiss' Kappa method in the search for concordance between physicians.

Results: A Fleiss Kappa coefficient of -0.078 (95 %CI -0.123 to -0.033) was obtained. This negative value, statistically significant (p=0.001), indicated that the overall concordance between physicians was less than expected by chance, so that there was more disagreement than coincidence in the categorization of the pulmonary records analyzed. In addition, negative Kappa coefficient values were found in all the interpretative categories evaluated, confirming the lack of inter-observer agreement previously determined globally.

Conclusions: No category reached a minimum level of agreement among physicians, which emphasizes the need for retraining and establishment of consensus on the criteria to consistently and accurately classify the sound characteristics of pulmonary recordings.
