A new article in JAMA Cardiology discusses the design of ADAPTABLE, a pragmatic clinical trial (PCT) which strives to answer a three-decade-old question with great potential significance for public health. ADAPTABLE is the first PCT to use many of the data-driven and patient-centric capabilities of the National Patient-Centered Clinical Research Network (PCORnet).
Researchers in ADAPTABLE pursued the unanswered question of whether a low dose or high dose of aspirin is optimal for secondary prevention of atherosclerotic cardiovascular disease. Complexities of running a randomized clinical trial and the expenses associated with it have previously prevented researchers from answering this question.
The capabilities of PCORnet have aided in this research. Though not all randomized clinical trials can be designed as PCTs, ADAPTABLE demonstrates the possibility of incorporating pragmatic elements into future studies with the goal of producing real-world evidence.
A key objective of involving PCORnet in ADAPTABLE was the ability for large-scale recruitment (15,000 participants) using electronic health records and electronic informed consent. The PCORnet component permitted complete electronic participation, from randomization to data collection. Patients reported their own data during scheduled electronic follow-ups, which replaced conventional follow-up visits.
NIH Collaboratory Coordinating Center co–principal investigator Dr. Adrian Hernandez also serves as co–principal investigator of ADAPTABLE and contributed to the article.
