Aim-To determine the diagnostic accuracy of physical examination by oYce based (general practice) paediatricians in the evaluation of heart murmurs. Design-Each of 30 oYce based paediatricians blindly examined a random sample of children with murmurs (43% of which were pathological). Sensitivity and specificity were calculated and were related to paediatricians' characteristics. Results-Mean (SD) sensitivity was 82 (24)% with a mean specificity of 72 (24)% in diVerentiating pathological from innocent murmurs, with further investigations requested for 54% of assessments. The addition of a referral strategy would have increased mean sensitivity to 87 (20)% and specificity to 98 (8)%. Diagnostic accuracy was not significantly related to the paediatricians' age, education or practice characteristics, but was related to referral practices and confidence in assessment. Conclusions-Diagnostic accuracy of clinical assessment of heart murmurs by oYce based paediatricians is suboptimal, and educational strategies are needed to improve accuracy and reduce unnecessary referrals and misdiagnosis.
