REGISTRIES

CHAT Consortium Phase II Studies Kick Off in 2020!

The Children’s Hospital-Acquired Thrombosis (CHAT) Consortium created the first large-scale, multi-institutional Registry including pertinent medical data from children with confirmed HA-VTE and non-VTE subjects. Data from this Registry has defined risk factors for HA-VTE in pediatric patients and created risk assessment models (RAMs) that will now be validated in order to develop a stratified scoring system.

Several HTRS members – Drs. Brian Branchford, Julie Jaffray, and Arash Mahajerin, under the mentorship of Drs. Neil Goldenberg, Diane Nugent, Vince Faustino, Guy Young, and Neil Zakai --  in collaboration with USC/CHLA Biostatistics and Johns Hopkins All Children's Hospital Predictive Analytics, have completed  Phase I data analysis for the multivariate risk assessment models.

in July 2019, CHAT became a consortium and many sites are in the process of joining the consortium or are in study startup.  The CHAT Consortium now has three studies:

1. CHAT Registry: New HA-VTE cases continue to be added

2. CHAT 1901: Prospective validation of the risk assessment model in PICUs (17 sites participating)

3. CHAT 1902 (sister study to CHAT 1901): Testing biomarkers to determine their ability to predict HA-VTE (4 sites participating)

The CHAT studies have been supported by multiple HTRS Mentored Research Awards, among others. The CHAT Newsletters, designed to keep participating or interested institutions up-to-date, are provided below:
