BackgroundAs the focus has grown in recent years on both engaged research and dissemination and implementation (D&I) research, so too has federal funding to support these areas. The purpose of this analysis is to provide an overall perspective about the range of practices and approaches being used to engage partners in D&I research, with special attention to disparities-relevant research, and to identify gaps and opportunities in research funded by the US National Institutes of Health (NIH) in this space.MethodsThis analysis examined a portfolio of active D&I research grants funded in fiscal years 2020 and 2021 across the NIH. Grant applications were deductively coded and summary statistics were calculated. Cross-tabulations were used to identify trends by engagement and disparities foci.ResultsThere were 103 grants included in the portfolio, of which 87% contained some form of community or partner engagement, and 50% of engaged grants were relevant to health disparities. Engagement was planned across the research continuum with each study engaging on average 2.5 different partner types. Consultation was the most common level of engagement (56%) while partnership was the least common (3%). On average, each study used 2.2 engagement strategies. Only 16% of grants indicated formally measuring engagement. Compared to non-disparities studies, disparities-relevant studies were about twice as likely to engage partners at the higher levels of partnership or collaboration (19% vs. 11%) and were also more likely to be conducted in community settings (26% vs. 5%).ConclusionsBased on this portfolio analysis, D&I research appears to regularly integrate engagement approaches and strategies, though opportunities to deepen engagement and diversify who is engaged remain. This manuscript outlines several gaps in the portfolio and describes opportunities for increasing engagement to improve the quality of D&I research and application to advancing health equity. In addition, opportunities for leveraging the consistent and systematic application of engagement approaches and strategies to advance the science of engagement are discussed.
