AN INVITATION TO PARTICIPATE IN AN
INTERNATIONAL REGISTRY TO STUDY DAILY
& NOCTURNAL HEMODIALYSIS
The Frequent Dialysis Regimens Workgroup of the Lawson Health Research Institute (LHRI) in London, Ontario, Canada, has recommended an international registry as an important step in establishing the future role of daily (quotidion) dialysis regimens.
This initiative is endorsed by the U.S. National Institutes of Health (NIH), National
Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and the International Society for Hemodialysis (ISHD). The specific goals of the Registry are to:
1. evaluate a spectrum of outcomes both before and after switching from
conventional thrice-weekly hemodialysis (CHD) to quotidian dialysis.
2. conduct a matched cohort-control study using CHD patients registered in
the United States Renal Data System (USRDS) and the Canadian Organ
Replacement Register (CORR) as control subjects.
3. obtain data describing quotidian dialysis practices and associated outcomes
to assist in the development of new technologies and create practice
Prospective data will be collected on prevalent and incident patients. In addition
to demographic, comorbidity, and biochemical data, centers will be asked
to report endpoints such as hospitalization, death, modality change, and vascular
All participating centers will have access to their own patient- and center-specific
data, as well as pooled-data reports.
Any centers prescribing dialysis regimens, with a frequency of five or more
treatments per week, are welcome to enroll and can obtain further information
by sending a request by email to: email@example.com or fax 519.685.8395.
