Blood Pressure Before Initiation of Maintenance Dialysis and Subsequent Mortality.

ABSTRACT:

Background

Mortality is extremely high immediately after the transition to dialysis therapy, but the association of blood pressure (BP) before dialysis therapy initiation with mortality after dialysis therapy initiation remains unknown.

Study design

Observational study.

Setting & participants

17,729 US veterans transitioning to dialysis therapy in October 2007 to September 2011, with a median follow-up of 2.0 years.

Predictor

Systolic (SBP) and diastolic BP (DBP) averaged over the last 1-year predialysis transition period as 6 (<120 to ≥160mmHg in 10-mmHg increments) and 5 (<60 to ≥90mmHg in 10-mmHg increments) categories, respectively, and as continuous measures.

Outcomes & measurements

Postdialysis all-cause mortality, assessed over different follow-up
