Early Career Researchers Respond to Cross-Cutting Principles for Dementia Care Pragmatic Trials: Lessons Learned6/24/2026Publications/Articles
(Article) This forum article describes pragmatic data sources across diverse healthcare settings in dementia care research. Through case examples, we show how early career researchers (ECRs) can innovate to identify and collect pragmatic data despite challenges. These case examples highlight unique data sources across disciplines, including nursing, social work, neuropsychology, occupational therapy, and speech-language pathology. They also illustrate creative approaches to using pragmatic data in each setting, encouraging ongoing innovation in dementia care research.

Words matter: an examination of terminology to define culturally informed dementia caregiving interventions5/11/2026Publications/Articles
This work aims to demonstrate the importance of culturally informed interventions to address disparities in care outcomes and clarify the meaning of the terminology of culture (i.e., cultural tailoring, cultural adaptation) and to provide exemplars of evidenced-based supports that utilized the term in dementia caregiving support.
Designing Consent Processes for Research that Enrolls Older Adults Who May Lack Decisional Capacity: A Practical Guide for Investigators5/7/2026Publications/Articles
(Article) Investigators outline an eight step framework for designing a study-specific consent process to help researchers anticipate and address common challenges and ensure they fulfill their ethical and regulatory obligations when  writing the human subjects portion of grant applications, preparing protocols for IRB submission, and seeking consent in the course of research.
Model-robust standardization in stepped wedge cluster randomized trials4/29/2026Publications/Articles
(Article) Investigators propose a model-robust standardization framework for SW-CRTs that generalizes existing methods from parallel-arm CRTs to address informative sizes.

Using the Readiness Assessment for Pragmatic Trials (RAPT) Model to Structure Partner Engagement and Strengthen Pragmatic Research Readiness3/25/2026Publications/Articles
(Article) Translational Science Case Study.  Brown University researchers and Bluestone Physician Services leaders used the Readiness Assessment for Pragmatic Trials (RAPT) model to structure joint planning for a study to improve end-of-life care. Collaborative completion of RAPT created a shared Cambridge University Press Journal of Clinical and Translational Science For Peer Review process for assessing feasibility, contextual fit, and alignment with Bluestone priorities. The exercise identified domains needing refinement and guided planning to strengthen data, workflows, and measurement, demonstrating that RAPT can serve as a practical framework for early stage co-design in pragmatic research.

Getting to the bottom of TMLE: targeting in action3/18/2026Other
(Blog post) Fourth post in the blog series exploring targeted maximum likelihood estimation or targeted minimum-loss estimate (TMLE).  In this post Dr. Goldfeld uses simulation to look directly at what targeting changes. He compare two estimators of the average treatment effect (ATE)—the plug-in estimator and TMLE—with the goal of understanding what the targeting step is doing mechanically and how it affects the final estimate.
