The International Society of Peritoneal Dialysis recommends that adequate blood pressure (BP) assessment among patients on peritoneal dialysis should at least include measurements performed once-weekly at home and at each visit at clinic. However, the quality of evidence to support this guidance is suboptimal. Using ambulatory daytime BP as reference standard, we explored the diagnostic performance of clinic and home BP recordings in a cohort of 81 stable patients receiving peritoneal dialysis. BP was recorded using 3 different methodologies: (1) triplicate automated clinic BP recordings after a 5-minute seated rest with the validated monitor HEM 705 CP (Omron Healthcare); (2) 1-week averaged home BP recorded with a validated automated monitor on awaking and at bedtime; and (3) ambulatory BP monitoring with the Mobil-O-Graph device (IEM, Germany). The area under the curve of receiver operating characteristic curves in detection of ambulatory daytime systolic BP (SBP) ≥135 mm Hg was similar for clinic [area under the curve, 0.859; 95% CI, 0.776-0.941] and home SBP (area under the curve, 0.895; 95% CI, 0.815-0.976). In Bland-Altman analysis, clinic SBP overestimated daytime ambulatory SBP by 5.02 mm Hg with 95% limits of agreement ranging from -17.92 to 27.96 mm Hg. Similarly, home SBP overestimated daytime ambulatory SBP by 4.23 mm Hg, again with wide 95% limits of agreement (-16.05 to 24.51 mm Hg). These results show that 1-week averaged home SBP is of at least similar accuracy with standardized clinic SBP in diagnosing hypertension confirmed by ambulatory BP monitoring among patients on peritoneal dialysis. © 2019 American Heart Association, Inc.
