The OMRON HEM-907XL is a commercial oscillometric blood pressure (BP) monitor that was used in the Systolic Blood Pressure Intervention Trial (SPRINT), in which 28% of participants had chronic kidney disease (CKD). This study examined the accuracy of the monitor in nondialytic patients with CKD. Eighty-seven patients met inclusion criteria. The authors used a modified Association for the Advancement of Medical Instrumentation (AAMI) protocol, with one observer recording measurements from the monitor and two blinded physicians obtaining simultaneous aneroid values by auscultation. Using AAMI method 1, there was a 2.5±9.5 mm Hg difference in OMRON and aneroid systolic BP, and a -1.6±6.5 mm Hg difference in diastolic BP. Using AAMI method 2, there was a 5.1±7.4 mm Hg difference in systolic BP and a -0.2±5.4 mm Hg difference in diastolic BP. In patients with CKD, the OMRON HEM-907XL appears to be accurate for measuring diastolic BP, but did not perform as well for systolic BP.
