International Intestinal Transplant Registry (IITR)

About Registry
Intestinal Registry’s Scope

The mission of the ITR is to provide data on the outcomes of intestine transplantation to the international intestine transplant community in order to support their efforts and improve outcomes as well as inform policy development.

The Intestinal Transplant Registry (ITR) is currently managed by the Intestinal Transplant Association (ITA) under the direction of Matthew Everly. Analyses are directed by the Research Committee of the Association.

The Registry has collected data on the world-wide outcomes of intestine transplantation since 1985. Data are provided every two years by participating centres. It is compiled, verified, analyzed, and presented in aggregate form only at the Bi-Annual meeting of the ITA. Specific queries about outcomes are provided to participating centres upon request.

Data Collected
Currently, the Registry collects the following information:

  • Donor information
  • Recipient demographics, such as gender and age
  • Pre-transplant diagnosis leading to transplant
  • Pre-transplant status (the patient’s condition before transplant)
  • Type of transplant (bowel; bowel & liver; or “cluster transplant”)
  • Post-transplant status and complications
  • Anti-rejection drugs taken by patients


  • Descriptive reports of donor and recipient profiles; and transplant outcomes
  • Inferential Analyses to determine factors affecting outcomes by means of:
    1. Pre-transplant diagnosis leading to transplant
    2. Pre-transplant status (the patient’s condition before transplant)
      • Univariate analyses (data checking and validation)
      • predictive multinomial model building

Privacy and Confidentiality
Data are presented in aggregate form only, and international privacy and data security have been met ensure patient data and centre confidentiality.

ITR Update Forms

It is highly advisable that the update be done electronically, through the Microsoft Access file sent to each centre. If this is not possible, we have set up an online form on this site that allows paper based centres to update without the need to physically mail the forms or fax them.

Please fill out the online form for each patient, AND attach the corresponding PDF* form for each patient for verification purposes.

In case of any doubts or inquiries regarding ITR patient forms please contact:
