Meta-research in pharmacy: Time for a look in the mirror.

The volume of the biomedical literature continues to expand at a substantial rate. The research literature surrounding pharmaceutical services is no different. Due in part to events in the recent past, researchers, consumers, funders, and policymakers have raised concerns about the credibility, transparency, and potential waste in the global research enterprise. Meta-research, or research on research, provides a way to examine the efficiency, quality, and potential bias in the overall research ecosystem. The field of meta-research is a relatively new but rapidly growing field that has seen many applications in biomedical research. Applications in pharmacy research, however, are still developing. The goals of this commentary are to introduce pharmacy researchers to the concept of meta-research, discuss several examples of meta-research in pharmacy, and motivate the importance of sustained meta-research efforts in pharmacy.
