Grand Rounds: Using a Pilot to Test and Refine Your Measurement Strategy

January 23 @ 12:00 pm - 1:00 pm

A hallmark of embedded pragmatic trials (ePCTs) is use of existing data sources to evaluate study outcomes. In ePCTs focused on people with dementia, behavioral outcomes of interest are often under-documented in the existing administrative data. Using a case example, we describe how a pilot can be used to test the adequacy of existing data for evaluating your ePCT outcome. We also describe a potentially efficient ePCT design that accommodates under-detection in existing data while maintaining large-scale implementation and evaluation.


Ellen McCreedy, PhD, MPH
Assistant Professor, Center for Gerontology and Healthcare Research, Brown University School of Public Health

Ellen McCreedy, PhD, MPH is interested in improving the quality of life for people living with advanced dementia. Her research goals are to reduce the amount of futile and burdensome care received at the end of life; and to provide comfort, meaning, and moments of joy to people living with dementia and their families. Professor McCreedy received her MPH in Global Health from the University of South Florida, her PhD in Health Services Research from the University of Minnesota, and recently completed a postdoctoral research fellowship at Brown University, Center for Gerontology and Healthcare Research. Dr. McCreedy is directing a pragmatic trial of a personalized music intervention to reduce agitation and isolation in nursing home residents living with dementia.

Learning Objectives

  1. Describe how a pilot study can be used to test the adequacy of existing data sources for the purposes of evaluating your ePCT.
  2. Give three reasons why existing administrative data may suffer from under-detection of behaviors in persons with dementia.
  3. Discuss an alternative ePCT design that addresses potential under-detection in existing administrative data sources.
