Abstract
High blood pressure, screened through obtaining a patient's blood pressure (BP), is found in 1 out of 3 U.S. adults and is increasing in prevalence.6 A cohort of 39 subjects had their BP measured following American Heart Association (AHA) protocol, utilizing three different measurement devices: manual sphygmomanometer (MA), automated Midmark IQvitals (IQ), and an automated Omron home unit (OM). All subjects also had their BP measured with the IQ device while not adhering to the AHA protocol. The two protocol conditions were denoted PR (protocol following AHA guidelines) or TY (typical clinical measurement lacking protocol). The results demonstrated a mean systolic BP with IQ-TY (123.7mmHg) > OM-PR (118.3mmHg) > IQ-PR (114.8mmHg) > MA-PR (111.0mmHg), all statistically significant (p<0.01). The mean diastolic BP for IQ-TY (79.6mmHg) > IQ-PR (71.15mmHg), OM-PR (71.05mmHg), and MA-PR (70.0mmHg), with IQ-TY significantly higher than the other 3 (p<0.01). When comparing the number of participants categorized in each hypertension stage, IQ-TY categorized 7participants as stage 1 hypertensive while OM-PR categorized 3, and both MA-PR and IQ-PR only categorized 1. These study results would suggest that there is a potential for possible misclassification of patients based on BP protocol.
