Dialysis Unit Blood Pressures
The “reverse epidemiology” of hypertension and mortality among dialysis patients has been described using BP measured in the dialysis unit using oscillometric technique and without adherence to standardized BP measurement methods. To reflect this practice and allow comparisons with larger cohorts, BP was measured by routine oscillometric technique in the dialysis unit. Accordingly, dialysis unit BP recordings were obtained by the dialysis unit staff using the sphygmomanometer equipped with hemodialysis machines without a specified technique and were averaged over 2 weeks surrounding the ambulatory BP measurement. Thus, each patient had 6 predialysis and 6 postdialysis BP recordings to provide routine dialysis unit BP
