Key result
AMA MAP Hypertension program improves SBP, but Black patients remain ~4% less likely to achieve control.
Why the study?
This study assessed differences in blood pressure control rates and systolic blood pressure values during the AMA MAP Hypertension quality improvement program to identify variations across demographic subgroups.

Does the AMA MAP™ Hypertension quality improvement program improve blood pressure control rates and SBP values across demographic subgroups?
A hypertension quality improvement program successfully lowered systolic blood pressure across all demographics, though racial disparities in achieving blood pressure control persisted.
Answers are grounded in this paper and cite their sources.
May support hypertension QI programs in safety-net settings; leaves open whether equity-focused adaptations can close persistent racial disparities.
Background This study assessed differences in blood pressure control rates and systolic blood pressure (SBP) values at Cook County Health (CCH) implementing the AMA MAP™ Hypertension quality improvement program, with the goal of identifying variations across demographic subgroups including race, ethnicity, sex and age. Methods We conducted a retrospective cohort study at CCH, comparing a 2-year historical pre-intervention with a subsequent 2-year period encompassing implementation and post implementation. Within each demographic subgroup, control rates were calculated as proportion of patients with controlled blood pressure. Univariate analyses assessed changes in blood pressure (BP) control over time. Prevalence ratio estimates were calculated to understand likelihood of having controlled blood pressure. Paired t-tests evaluated within-group changes in SBP, and an ANCOVA was conducted to compare SBP changes between groups while adjusting for baseline SBP. Results Overall, blood pressure control rates increased over time. However, Black patients were less likely than White patients to have controlled blood pressure both before (PR 0.91 [CI: 0.87-0.96]) and after (PR 0.96 [0.92—0.99]) the implementation of the program. SBP improved across all demographic groups, including Hispanic (-5.74 [CI:6.19- -5.29]) and Non-Hispanic patients (-4.92 [-5.21- -4.63]), White (-5.96 [CI: -6.45- -5.47]) and Black (-4.80 [CI: -5.11- -4.49]) patients, and patients 45-64 years of age (-5.79 [CI: -6.12- -5.46]) and patients 65-85 years of age (-4.31 [CI: -4.68- -3.94]). Conclusions The AMA MAP™ Hypertension quality improvement program led to improvements in blood pressure control; however, gaps persisted in SBP values between ethnicity, race and age.

Zasadzinski et al. (2026) conducted a cohort in Hypertension. AMA MAP™ Hypertension quality improvement program vs. Historical pre-intervention period was evaluated on Blood pressure control rates and systolic blood pressure (SBP) values. Implementation of the AMA MAP™ Hypertension program improved systolic blood pressure across all demographics, but Black patients remained less likely to achieve control than White patients (PR 0.96).
