ACT Network

The ACT Network is a real-time platform allowing investigators to explore and validate feasibility for clinical studies across many of the NCATS Clinical and Translational Science Award (CTSA) sites, from their desktops. ACT helps investigators design and complete clinical studies and is secure, HIPAA-compliant and IRB-approved. You can use the platform to:

  • Explore patient populations: Learn about your patient population in depth and in real time, from your desktop.
  • Check feasibility of clinical studies: Iteratively test and refine inclusion and exclusion criteria to confirm the feasibility of your clinical study.
  • Find partner sites: Search for patient cohorts across the CTSA network to identify potential partners for multi-site studies.
  • Demonstrate feasibility: Access easy-to-download results for use in funding proposals and IRB submissions to demonstrate the feasibility of your clinical study.

ACT was developed collaboratively by members of the CTSA consortium, with funding from the NIH National Center for Advancing Translational Sciences. The operations of the Northwestern Medicine node of the ACT Network is approved by NU IRB protocol# STU00200519.

Regular Maintenance

Our connection to the ACT Network requires regular maintenance, which we align with the ACT Network's weekly scheduled maintenance time (Tuesdays at 3 p.m. until Wednesdays at 6 a.m. CT). Users should expect the system to be offline during this time and should be aware that maintenance can be in advance of or extend beyond this window depending on the scope of work.
