Pediatric Research recently published a series of articles highlighting the ECHO Program’s progress. In the introductory article, titled “The NIH ECHO Program: investigating how early environmental influences affect child health,” the NIH Program Office provides a broad overview of the program and its achievements to date. The second and third articles, written by members of the ECHO Coordinating Center (CC) and various ECHO investigators, focus on the program’s construction, challenges overcome during development, and the scientific opportunities that have already resulted from ECHO’s uniquely broad dataset.

The introductory article highlights the origins of the ECHO Program, dating back to September 2016. Authored by members of the NIH Program Office, this article details the breadth of the ECHO Program’s national network of cohorts, which includes 57,000 children and over 1,200 researchers participating through observational and interventional research. This piece also outlines program goals, including ECHO’s commitment “to enable high-impact research evidence that will inform clinical practices, policies, and programs for child health; and establish a national data platform and biorepository for the scientific community.”

Given its size and span, the program faced unique challenges. To tackle these head-on, governing committees facilitated the establishment of several specialized working groups to address challenges and direct the program in pursuing its goals. For example, the purpose of the Team Science Working Group was to “maximize ECHO’s scientific excellence and productivity by fostering team building and collaboration through effective communication.”

Another logistical challenge that ECHO faced from the beginning was the coordination of a dispersed set of established pediatric cohorts and the harmonization of their existing data to create a nationwide standardized dataset. As many of these individual cohorts had their own research focal points and routine sets of measurements, building a consistent dataset required ECHO to develop a unified set of required measurements and standard protocols. From this problem came the Protocol Working Group.

ECHO aims to enhance the health of children and adolescents through research that may help inform healthcare practices, programs, and policies. The third article details program strategies for fostering solution-oriented research that helps accomplish this goal, some of which include promoting ECHO research through publications and Opportunities and Infrastructure Fund (OIF) grants.

In the five years since its inception, the ECHO Program has made great strides in the development of a diverse, nationwide pediatric research framework with the power to inform children’s health policies and practices. Its large, varied population of participants, emphasis on multidisciplinary science, and capacity for pioneering innovative methods and technologies have shaped the program into an unprecedented resource in pediatric research.

“ECHO represents exciting new opportunities for pediatric research,” the third article concludes, “allowing for the investigation of scientific questions related to less common childhood outcomes and increasing inclusiveness of children participating in research in the United States.”
