Echocardiography Learning by Pediatricians While Screening Congenital Heart Disease with the Aid of Telemedicine.

Congenital heart disease (CHD) affects 1% of all newborns and is a major public health problem. Most children with CHD benefit from early diagnosis to optimize management. However, in many places there are no specialized professionals to do so. A screening method for CHD was developed between two states in Northeast Brazil. It was based upon the performance of an echocardiogram by local pediatricians with support of pediatric cardiologists through telemedicine. To determine if the continuous performance of examinations together with online supervision increased the level of understanding of the pediatricians about the echocardiograms. Pediatricians received online support to perform echocardiograms for 7 years (2012-2018). Although the project aimed to teach them to acquire images and send to the cardiologists for analysis and interpretation, they were encouraged to describe their own diagnostic impressions. The level of agreement between pediatricians and cardiologists was calculated. A large number ( = 3,951) echocardiograms was analyzed. From them, 2,818 were classified as abnormal, inconclusive, or normal by both the pediatricians and the cardiologists. The 7-year analysis demonstrated an overall agreement of 63.7%. As for the final diagnosis, it was possible to compare 1,457 echocardiograms. The combined analysis of the 7 years demonstrated agreement in 62.2%. The screening of CHD under online support led to more in-depth learning of echocardiography by the pediatricians. This approach potentialized the accuracy of the screening through the years. By enrolling in a telemedicine-based screening program, the pediatricians' degree of understanding of echocardiography increased considerably.
