A Patient‐Centered Approach to Comparative Effectiveness Research Focused on Older Adults: Lessons From the Patient‐Centered Outcomes Research Institute

The mission of the Patient‐Centered Outcomes Research Institute (PCORI) is to fund the production of high‐quality evidence that will enable patients and clinicians to make informed, personalized healthcare decisions. Since 2012, the PCORI has invested $177 million in patient‐centered comparative effectiveness research (CER) that specifically targets the health needs of older adults, with additional relevant studies in its broader portfolio. Developing the PCORI's research portfolio has provided us with significant insights into what factors to consider when conducting CER in older adult populations. When comparing the net benefit of two or more interventions for older adults, investigators should consider the following: absolute risk difference, competing risks, life expectancy, the difference between chronologic and physiologic age, the importance of patient preferences, and other potential drivers of variable treatment effects. Investigators should also engage older adults and their caregivers as partners throughout the research process. Their input helps to identify key outcomes of interest and insights about the conduct of the research. As the PCORI continues to support research that addresses the healthcare decisions of the rapidly growing older adult population, it needs to partner with patients and researchers to identify the most important questions to address.
