CHAT (Children’s Hospital-Acquired Thrombosis Study) Is Looking for New Sites


Several HTRS members, Brian Branchford, MD, Julie Jaffray, MD, and Arash Mahajerin, MD, MSCr, under the mentorship of members Neil Goldenberg, MD and Guy Young, MD, have started a pediatric hospital-acquired blood clot registry to track such events and eventually look at how they can be prevented. This project received a 2016 HTRS Mentored Research Award, among others.

The Children’s Hospital-Acquired Thrombosis (CHAT) study aims to create the first large scale, multi-institutional registry including pertinent medical data from children with confirmed HA-VTE and matched controls. Data from this registry will be used to define the risk factors for HA-VTE in pediatric patients and to create (Phase 1) and validate (Phase 2) a risk assessment model and stratified scoring system. 

The CHAT newsletters, designed to keep participating institutions up-to-date are provided below.

The organizers are looking for new sites to join. They currently have 6 -10 sites in various stages of commitment but are hoping for 80 -100.

Brian, Julie, and Arash would be very happy for interested parties to contact them by email with any comments or questions, or with a desire to join the registry.
