Key Points
- The research team reviewed the current challenges in adult congenital heart disease (ACHD) clinical care, surveillance, and long-term outcomes research, including a demand for subspecialty care that outweighs the supply; the heterogeneity of CHD and its long-term outcomes; and changing treatment strategies.
- Though there are several CHD registries in the U.S., very few focus on adults with CHD. The research’s teams efforts, beginning with the Congenital Heart Initiative (CHI) launch in 2020, came about in response to this gap.
- The mission of the CHI is to create a digital hub collecting health data from patients and providers. The team seeks to involve patients in every aspect of the CHI registry, with the ultimate goal of creating a community of ACHD patients and providers with a shared understanding of research needs and medical outcomes.
- As the registry initially lacked data from healthcare providers and the electronic health record, the team partnered with PCORnet to establish an ACHD surveillance system.
- The CHI-RON study uses PCORnet data and patient-reported outcomes to determine whether ACHD patients who are receiving recommended care do better than those who are not and the impact of gaps in care on patient-reported outcomes.
- Dr. Carton provided an overview of PCORnet, followed by a review of the data science innovations the team used to generate a computable phenotype, identify congenital heart providers, diversify demographic recruitment for the registry, and incorporate procedure results into the common data model for analysis.
- One of the strengths of this project was the high degree of patient and partner engagement. This involvement led directly to programming such as the “ACHA Café,” a virtual coffee hour in which patients could engage with one another, and guided their social media content.
Discussion Themes
The ACHD patient population identified a few key topics that they hoped the CHI would explore, including long-term effects of congenital heart defects, the most effective therapeutics for treating CHD, and mental health care options. Patient partner feedback also helped the team refine their recruitment and outreach materials.
Given the tendency for some types of CHD to be given more attention than others, the research team sought to enroll a patient population that was inclusive of a variety of presentations. This presented some methodological challenges, e.g. when it came to drawing distinctions in the registry.
