Abstract
BACKGROUND
Focused cardiac ultrasound (FCU) is a helpful tool to rapidly identify right ventricular (RV) causes of hemodynamic instability and facilitate the initiation of therapy. The clinical value of existing course models often remains unclear. This study investigated the effects of a one-day FCU training on the visual estimation skills of RV characteristics.
METHODS
Four residents were included as the study group after completing a standardized one-day FCU training. Four gender-matched controls did not take part in the training. All residents graded image quality, RV systolic function, and RV dimensions in a test comprising 35 ultrasound clips.
RESULTS
The study and control group did not differ in ICU or ultrasound experience. Overall, training participants were able to distinguish between good and insufficient image quality significantly better than the control group (agreement 80.0% vs 61.4%, p = 0.04). The agreement for the estimation of RV function and RV dimensions was not different between the groups (63.2% vs 60.5%, p = 0.66 and 64.3% vs 67.1%, p = 0.18, respectively). Descriptively, only small differences were found between the groups for the estimation of RV function and RV dimensions in subgroups of patients with normal versus reduced systolic RV function or normal versus enlarged RV dimensions, respectively. Both groups struggled in identifying RV enlargement (34.6% vs 46.2%).
DISCUSSION
In this study, a single one-day FCU training had no impact on residents' skills to visually assess systolic RV function or RV dimensions. Improvements of current training modalities or continuous teaching models are needed to optimize residency programs and patient care.
