Using virtual multiteam systems to conduct a multisite randomized clinical trial in the part C early intervention system: Benefits, challenges, and lessons learned.

Background/aims: COVID-19 necessitated a shift to virtual data collection for many research projects, providing the opportunity for novel approaches to carrying out multi-site clinical trials. Virtual multiteam systems (VMTS) are a type of team structure in which multiple geographically dispersed teams collaborate using technology-mediated communication. The article presents a case study of our use of VMTS, in response to COVID-19, to carry out a multisite randomized hybrid effectiveness-implementation trial of a caregiver-implemented intervention.
