Accuracy of clinical assessment of heart murmurs by office based (general practice) paediatricians
Free

Abstract

AIM To determine the diagnostic accuracy of physical examination by office based (general practice) paediatricians in the evaluation of heart murmurs.

DESIGN Each of 30 office 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 differentiating 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 office based paediatricians is suboptimal, and educational strategies are needed to improve accuracy and reduce unnecessary referrals and misdiagnosis.
