IMPACT Collaboratory members Spencer Hey, PhD and Monica Taljaard, PhD are among the authors of a review of pragmatic clinical trials recently published online in the Journal of Clinical Epidemiology and covered in a blog post from the US GRADE network. The first author of the study is Stuart G. Nicholls, PhD, of the Ottawa Hospital Research Institute.
The researchers identified 4,337 eligible trials in their review of data collected from MEDLINE, Web of Science, ClinicalTrials.gov and full text between January 2014 and April 2019. They found diversity in research areas, but only 22% of the trials identified were labeled as pragmatic in the title, abstract or full text of the document. In addition, the authors estimated one-fifth of trials under-accrued by at least 15%. They concluded that there is a need to improve reporting of pragmatic trials and quality of trial registry data. Under accrual remains a challenge in pragmatic RCTs despite calls for more streamlined recruitment approaches.
The US GRADE Network blog developed an infographic to share the findings of the review.
