About this study
Official title: The Effect of MDRD GFR Reporting on Nephrology Referral Patterns by Internists
The addition of an estimate value of glomerular filtration rate (GFR) per Modification of Diet in Renal Disease [MDRD] (LEVEY) equation is being included and reported on all routine chemistry panels in the experimental group. The control group is only having serum creatinine, the current standard of care, reported on routine chemistry panels.
Read the detailed description
All patients already referred to or being followed by nephrologists were excluded. Inclusion criteria were all patients in the Internal Medicine clinic at NMCSD who were sent to the lab to obtain routine chemistry panels for follow up by their primary care providers. The primary outcome is increased referral to nephrology in accordance with NKF K/DOQI guidelines if GFR values are reported on routine chemistry panels. Key secondary outcomes are Primary Care Provider knowledge of NKF K/DOQI guidelines, specifically when patients with chronic kidney disease need to be referred to a nephrologist for further evaluation.

What is being measured
The primary outcome is the main question the study is designed to answer.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incraesed referral to nephrology inaccordance with NKF K/DOQI guidelines if GFR values are reported on routine chemistry panels.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
