Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • To determine whether Point of Care INR testing would be suitable in the management of dialysis patients on chronic warfarin therapy [ Time Frame: Not an intervention study, but observational in this cohort ]

Secondary Outcome Measures:
  • Determine whether Point of Care INR devices maintain test accuracy in dialysis patients who are temporarily anemic (HCT <32%) according to their CBC [ Time Frame: Not an intervention study, but observational in the cohort (statistics completed 1.5 yrs) ]

Enrollment: 37
Study Start Date: June 2005
Study Completion Date: December 2005
Primary Completion Date: December 2005 (Final data collection date for primary outcome measure)
Groups/Cohorts
37 dialysis patients
37 chronic hemodialysis patients on warfarin requiring Laboratory INR monitoring for anticoagulation management.

Detailed Description:
37 chronic hemodialysis patients being anticoagulated with warfarin require INR monitoring routinely.
