At our site, we have a small number of hemodialysis out-patients that we follow for Warfarin dosing. Thankfully, they all come during the same hemodialysis days, so it helps with workflow. We only dose patients on a referral basis, and these patients must be scheduled for dialysis during the daytime shifts at the hospital (no satellite sites, no evenings/nocturnals) to ensure that we can provide proper follow-ups. When we first started dosing Warfarin, we had a larger number of patients. But as the years went on, some of the patients were able to discontinue Warfarin or switch to a DOAC, so we do have as many patients now.
