ABSTRACT

BACKGROUND: Heart disease remains a leading cause of morbidity and mortality, particularly in low- and middle-income countries. Access to diagnostic modalities is limited in these settings. Limited echocardiographic studies performed by non-cardiologists can increase access, improve diagnosis and allow for earlier medical therapy.

METHODS: Two internal medicine residents at a tertiary-level hospital in Ghana were trained to perform limited echocardiographic studies. Each trainee performed 50 echocardiograms and interpreted 20 studies across three predetermined timepoints. Interpretation was compared to expert interpretation.

RESULTS: Agreement improved over time. At the final evaluation, there was high agreement across all aspects: left ventricular structure (70%, kappa 0.52, = 0.01), left ventricular function (80%, kappa 0.65, = 0.004), right ventricular structure (90%, kappa 0.71, = 0.002), right ventricular function (100%, kappa 1.00, < 0.001), and presence of effusion (100%, kappa 1.00, < 0.001).

CONCLUSIONS: Non-cardiologists can be trained in focused echocardiography using handheld machines. Such training can increase access to diagnostic capabilities in resource-limited settings.
