Abbreviation: BP, blood pressure.
Baseline was defined as the date of the patient’s first visit during which elevated BP was recorded.
Includes American Indian or Alaska Native (77 patients [0.4%]), Native Hawaiian or Pacific Islander (217 patients [1.3%]), and unknown (819 patients [5.1%]).
Includes adult patients with diagnosed hypertension who had 1 or more visit during which elevated SBP (≥140 mm Hg) was recorded between 2015 and 2017 and at least 2 visits during which elevated BP was recorded in the last 12 months.
Uncontrolled hypertension was defined as an SBP level of 140 mm Hg or higher. Stage 1 was defined as a systolic BP (SBP) level of 140 mm Hg to 159 mm Hg; stage 2 as an SBP level of 160 mm Hg to 179 mm Hg; and severe hypertension as an SBP level of 180 mm Hg or higher.
