Why the study?

Hypertension control in large populations remains challenging, and data on the effects of a hypertension control program in the understudied Hispanic population in South Florida are limited.

Does a multicomponent hypertension control program improve blood pressure control in older Hispanic Medicare beneficiaries with hypertension?

Population

Patients aged 65-89 years with hypertension in South Florida (n=4,710 in 2008 to n=21,540 in 2018)

Comparison

Pre- vs post-implementation of a multicomponent hypertension control program

Design

Longitudinal electronic health record cohort study

Key result

Implementation of a multicomponent hypertension control program was associated with a significant increase in blood pressure control, with the adjusted odds of controlled BP being 5.84 times higher after full implementation compared to the pre-program period.

Structured PICO

Does a multicomponent hypertension control program improve blood pressure control in older Hispanic Medicare beneficiaries with hypertension?

P
Population
Medicare and dual eligible patients aged 65-89 years with hypertension, primarily of Hispanic origin (>98%), receiving care in 7 outpatient centers in Miami-Dade, FL. Sample size ranged from n=4,710 (2008) to n=21,540 (2018).
I
Intervention
Multicomponent hypertension control program implemented in 2011, including team-based care, dedicated care management unit, standardized BP measurement protocols, EHR registry, automatic follow-ups, patient education, pharmacy services, and transportation.
C
Comparator
Pre-implementation period (2008-2010) standard of care.
O
Outcome
Blood pressure control (systolic <140 mmHg and diastolic <90 mmHg) assessed by time-average BP (AVG-BP) and last visit BP (LAST-BP).surrogate

Main Result

Effect estimate: OR 5.84 (95% CI 5.56-6.14)

Absolute Event Rate: 89.7% vs 73.1%

Implementation of a multicomponent, team-based hypertension control program in a large health system was associated with a substantial and sustained increase in blood pressure control among older Hispanic Medicare beneficiaries.

Limitations

  • Observational study design
  • Open cohort with changing population structure over time
  • Secondary analysis of electronic health records data

Cite This Study

Chaves et al. (2025) conducted an observational in Hypertension (n=21,540). Multicomponent Hypertension Control Program vs. Pre-implementation period (2008-2010) was evaluated on Controlled blood pressure (systolic <140 mmHg and diastolic <90 mmHg) based on time-average BP (OR 5.84, 95% CI 5.56-6.14). Implementation of a multicomponent hypertension control program was associated with a significant increase in blood pressure control, with the adjusted odds of controlled BP being 5.84 times higher after full implementation compared to the pre-program period.
