Latino-White Disparities in Identification and Control of Elevated Blood Pressure Among Adults With Hypertension.

BACKGROUND

Studies analyzing blood pressure (BP) management using the hypertension control cascade have consistently shown disparities in hypertension awareness, treatment, and BP control between Latino patients and non-Latino White patients. We analyze this cascade using electronic health record data from a multistate network of community health centers.

METHODS AND

RESULTS

Data from 790 clinics in 23 US states from 2012 to 2020, including 1 270 174 patients, were analyzed to compare BP documentation in the electronic health record, clinician acknowledgment (diagnosis or treatment) of incident hypertension (BP ≥140/90), medication prescription, and BP control between non-Latino White patients, English-preferring Latino patients, and Spanish-preferring Latino patients, adjusted for patient-level covariates, and clustered on patients' primary clinics. Among the 429 182 patients with elevated BP (≥140/90) during ambulatory visits from 2012 to 2020, we found that clinician acknowledgment of hypertension was more likely in Spanish-preferring and English-preferring Latino patients versus non-Latino White patients (adjusted odds ratio [aOR], 1.17 [95% CI, 1.11-1.24]; aOR, 1.07 [95% CI, 1.02-1.12], respectively). In addition, Spanish-preferring Latino patients were more likely to receive a medication versus non-Latino White patients (aOR, 1.21 [95% CI, 1.16-1.28]). Among those receiving medication, Latino patients were as likely as non-Latino White patients to have their BP controlled (<140/90).

CONCLUSIONS

In a large retrospective study of community health center patients with incident hypertension, the expected disparities in hypertension management between Spanish-preferring Latino, English-preferring Latino, and non-Latino White patients were not identified. These findings add to the hypertension control cascade by examining robust electronic health record data from community health centers and may provide clues to reducing disparities in hypertension management.
