Key result
Basic haemodynamic assessment using a hand-held echocardiography device by a novice operator achieved acceptable agreement with an expert following 20 training studies.
Why the study?
Does a novice operator achieve acceptable agreement with an expert operator when performing basic haemodynamic assessment using a hand-held echocardiography device in healthy volunteers?

Does a novice operator achieve acceptable agreement with an expert operator when performing basic haemodynamic assessment using a hand-held echocardiography device in healthy volunteers?
Novice operators can achieve acceptable basic haemodynamic assessment using hand-held echocardiography after a minimum of 20 training studies.
Supports novice hand-held echo feasibility after brief training; hypothesis-generating and should not yet change practice.
Miniaturization of ultrasound equipment has led to the development of hand-held echocardiography devices suitable for bedside evaluation of cardiac function. Basic assessment of the haemodynamic state can be performed using a limited transthoracic echocardiography examination. This study evaluated a third generation device (SonoSite Titan) used by novice and expert operators. Limited transthoracic examination was performed on 30 healthy volunteers by an expert and a novice operator. The novice had performed 10 studies prior to data accrual. Agreement analysis was performed using weighted least products regression and Bland-Altman analysis. Acceptable results for the novice were achieved following 20 studies (including practice sessions) for basic haemodynamic assessment and following 40 studies for all measured parameters. The SonoSite Titan is acceptable for basic transthoracic measurements to determine the basic haemodynamic state and cardiac output measurements. We recommend a minimum of 20 training studies for novice operators prior to clinical use.

Royse et al. (2006) conducted a cross-sectional in Healthy volunteers (n=30). Basic haemodynamic assessment using hand-held echocardiography by a novice operator vs. Expert operator was evaluated on Agreement of basic haemodynamic assessment and cardiac output measurements. Basic haemodynamic assessment using a hand-held echocardiography device by a novice operator achieved acceptable agreement with an expert following 20 training studies.
