Disagreement Between Observers in an Epidemiological Study of Respiratory Disease

ABSTRACfObservers differ in their judgment while 888888ing physical signs in a patient. We had undertaken a goitre prevalence survey amongst school students in a Rural Health Training Centre, Pune district (Maharashtra) during October 1992. Four te8IIIB of trained observers were used for detection ofgoitre. This study was undertaken to estimate the extent and acceptability of interobserver agreement amongst the four teams. Observer variation/agreement was measured by two methods viz. kappa coefficient and proportion of agreement. The proportion of agreement appears to be a better measure of observer agreement as it could make a distinction between normality (absence of goitre) and abnormality (presence ofgoitre). In the present study, the proportion ofagreement for abnormality ranSed between 0.62 -0.83. This measure was considered as indicating a good interobserver agreement in detecting goitre in the survey that was undertaken. MJAFI 1995; 51 : 95-99

“…German authorities reviewed by Worth and Schiller (1954) stress the importance of physical signs in the chest in addition to cough and sputum; but they also point out that added sounds may be evanescent. In view of the unreliability of physical signs in the diagnosis of chronic bronchitis (Schilling et al, 1955), we omitted a clinical examination and based the diagnosis on answers to the questionary.…”
