Trials are already being prioritised, just not at the institutional level

Successful clinical trials are important for all of us, but they can be extremely complicated to design and run, so work must be done to consider what commonly goes wrong and how these issues can be addressed. Gelinas et al suggest an ethical argument for institutional prioritisation of clinical trials conducted among limited populations. This is to ensure successful recruitment and prevent competing trials rendering each other irrelevant through lack of statistical power. But they overlook the fact that effective prioritisation already occurs, and their suggestion produces yet another hurdle for researchers to overcome.
