- Abstract
The article addresses the issue of underpowered trials in evaluating new care models, particularly in randomized controlled trials (RCTs). It highlights challenges like implementation issues and incomplete engagement, leading to ambiguous results. It suggests strategies for improving trial power, including cautious estimation of effect sizes, anticipating uptake challenges, using preparatory studies and others.
