Introduction: This analysis is a part of ongoing quality improvement efforts aiming at improving hypertension control among various racial minority groups seen in a large outpatient practice with a special focus on two war refugee populations, the Hmong and the Somali populations.
Method: Deidentified medical records were reviewed for adult hypertensive patients who had an outpatient encounter with a hypertension diagnosis during the years 2015 through 2019. The study outcome was the rate of uncontrolled hypertension, defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg, and stratified by race, age, and gender.
Results: There were 752,504 patient records representing 259,824 unique patients (mean age 61 ± 13 years) with 49.1% women, 82.1% white 8.3% African American, 4% Asian, 1.6% Hispanic, Somali 0.6%, and 0.2% Hmong. Hmong men had the highest rate of uncontrolled HTN (33.6%) followed by African American (31.3%) then Somali (29.2%). Among women, African Americans had the highest rate (28.6%) followed by Hmong (28.5%) then Somali (25.7%). In all races except Somali, the rate of uncontrolled hypertension was highest in the 18-29 age group, decreased progressively over the next several decades, then increased again in the ≥70 age group.
Conclusion: Hmong, African American, and Somali groups have the highest rates of uncontrolled hypertension. Efforts to address hypertension management need to be tailored to the specific characteristics of each racial group and to target young adults.
