The crisis in health and medical statistics

Jun 14, 2018 · Brisbane, Australia

The Presentation:

Health and medical research is vital for improving people’s lives. At its best it involves skilled researchers testing relevant questions using rigorous methods that translate into practice. Unfortunately much research fails to improve health because of long-standing issues such as inadequate training, poor regulation and perverse incentives. Recent attempts to reproduce peer reviewed papers in health and medicine had failure rates between 75% and 90%, and an estimated 85% of research is currently lost due to poor research practices.

Poor statistical practices are central to this “reproducibility crisis”. Many health and medical researchers – even those with years of experience – have little understanding of the correct definition of a p-value, confidence interval or confounder. Too many researchers follow the “publish or perish” maxim and salami slice their research and promote “statistically significant” findings that are not reproducible. The bias to publish “statistically significant” results means crucial evidence that fails to show a difference is often never published. Other crucial evidence may be suppressed because of conflicts of interest.

The problem with statistics is not the methods themselves, but in their application. Hence statisticians have a key role in tackling the current crisis by promoting best practice and training their colleagues. We can also study the problems and design evidence-based interventions to reduce them as part of the new field of meta-research or “research on research”. Although the current situation is grim there is enormous potential to increase the value of health and medical research by promoting better statistical practice.
