ABPM may offer more reliable BP assessment in hemodialysis; leaves open whether it improves outcomes over routine measurements.

Does 48-hour interdialytic ABPM provide better reproducibility than isolated or averaged pre- and post-hemodialysis BP measurements in hemodialysis patients?
In hemodialysis patients, 48-hour interdialytic ABPM is the most reproducible method for assessing blood pressure over time, although the reproducibility of nocturnal BP decline is poor.
Peixoto et al. (2000) conducted an observational in Hemodialysis (n=21). Ambulatory blood pressure monitoring (ABPM) vs. Isolated and averaged pre- and post-hemodialysis blood pressure was evaluated on Reproducibility determined by SD of differences (SDD) and coefficient of variation. Ambulatory blood pressure monitoring demonstrated better reproducibility (coefficient of variation 7.5%/8.1%) compared to isolated or averaged pre- and post-hemodialysis blood pressure measurements.
