Abstract
Background
Daily hemodialysis is a promising treatment schedule but uniform criteria for defining efficiency are lacking.
Methods
On our daily dialysis (DD) schedule, duration is flexible (2–3 hours, patients are free to add up to 30min/session), Qb 250–350 mL/min; dialyser 1.6–1.8 m2. Study was performed on 12 pts on DD for ≥2 months, with ≥4 Kt/V on subsequent days, tested in the same laboratory. Goal: To evaluate variability and identify a simple method for weekly calculation, Kt/V was assessed for 133 sessions.
Results
On flexible DD, variability of Kt/V-session is high (relative error 4.9%-22%). On flexible schedules, within the time range chosen (2–3 hours) variability of average hourly Kt/V is lower (standard deviation: min (0.014; max (0.052 hour, relative error 4.9%-10%) allowing calculation of weekly Kt/V (averaging 3 sessions: relative error <6%) suitable for clinical practice.
Conclusions
Flexible schedules, allowing patients to increase treatment time, are an interesting clinical option, but a challenge for Kt/V assessment.
