Preclinical Echocardiography: Training and Guidelines

Given the current conversations around rigor and reproducibility, and the need to reinforce scientific research to the public, our latest podcast is particularly timely. Deputy Editor Merry Lindsey (University of Mississippi Medical Center) interviews lead author Daniel Donner (Baker Heart and Diabetes Institute) and content expert Lisandra de Castro Bras (East Carolina University) about the unique study by Donner and colleagues focused on standardizing the quality of echocardiography in mice at Baker Heart and Diabetes Institute, Melbourne, Australia. Listen as we address the importance of consistent training for echocardiography readers on the analysis of echocardiographic images. Did Donner and co-authors find that implementing a short, formal preclinical echo training program at Baker Heart and Diabetes was as onerous as they originally anticipated? Power analysis in the study by Donner et al revealed that sample sizes needed to detect differences were reduced more than 50% after training. What are the implications of reductions in sample size on improving methodology, reducing animal numbers, and reducing research costs? Listen now.
