Objective: The objective of this study is to evaluate the inter-observervariability in the echocardiography interpretation. Settings and Design: Tertiary care hospital, Prospective study. Subjects: A total of 37 patients were included in the study.Echocardiography was done in each patient four times at 2 weeks intervalsby different cardiologists. Each cardiologist was blinded to the previousreports. Echocardiography reports of each patient were analyzed for anydiscrepancy in interpretation. The parameters used were left ventricularejection fraction, presence of diastolic dysfunction, presence of pulmonaryhypertension, regional wall motion abnormality, valve abnormality andoverall interpretation. Results: There was fair agreement with regard to diastolic dysfunction forreporter 1 and 2, reporter1 and 3, reporter1 and 4, reporter 2 and 3. Agreement was slight for reporter 2 and 4, reporter 3 and 4. Similarly fordetection of valvular abnormality, there was only a slight agreementbetween reporter 1 and 2, reporter 2 and 3. Agreement between reporter1and 3, reporter 1 and 4, reporter 2 and 4, reporter3 and 4 were fair for detection of valvular abnormality. Agreement for overall interpretation ofechocardiography showed better correlation for reporter1 vs reporter 3 and reporter2 vs reporter3. Correlation for other pairs was slight. Analysis ofLVEF measurement by Pearson’s correlation did not show statisticallysignificant difference between different observers. Conclusions: There was significant inter-observer variation with regard tothe interpretation of valve abnormality, diastolic dysfunction and overallinterpretation.
