Key result
Patients with insulin-dependent diabetes mellitus had a more severe overestimation of systolic blood pressure by the SpaceLabs 90207 device compared to healthy controls (1.7 mmHg difference, P=0.009).
Why the study?
Does the agreement between the SpaceLabs 90207 oscillometric device and the sphygmomanometer differ between insulin-dependent diabetic patients and healthy controls?
Population

May warrant caution interpreting oscillometric BP readings in insulin-dependent diabetes; leaves open need for subpopulation-specific device validation.
Observational (n=198)
Does the agreement between the SpaceLabs 90207 oscillometric device and the sphygmomanometer differ between insulin-dependent diabetic patients and healthy controls?
Mean Difference: 1.7
p-value: p=0.009
The limits of agreement between automated oscillometric blood pressure devices and sphygmomanometers differ significantly between diabetic patients and healthy controls, suggesting that device validation protocols should specifically evaluate such subpopulations.
Ittersum et al. (1998) conducted an observational in Insulin-dependent diabetes mellitus (n=198). Insulin-dependent diabetes mellitus (IDDM) vs. Healthy control subjects was evaluated on Difference in overestimation of systolic blood pressure between the SpaceLabs 90207 device and sphygmomanometer (MD 1.7 mmHg, p=0.009). Patients with insulin-dependent diabetes mellitus had a more severe overestimation of systolic blood pressure by the SpaceLabs 90207 device compared to healthy controls (1.7 mmHg difference, P=0.009).
