UC Systemwide Hypertension Program: Reported Population Outcomes and Implementation Features

A University of California (UC) initiative that embedded a standardized hypertension medication algorithm across its health system was associated with higher measured blood pressure control at the population level, according to a recent report. The report framed the findings as an observed shift in control rates rather than a definitive causal effect. It also described the scale of the rollout, a modeled translation of the change into estimated clinical events, and key milestones in how the program was built and deployed.

The report stated that the program covered about 90,000 patients across the UC system, including roughly 11,500 patients at UCSF, and that measured blood pressure control increased from 68.5% to nearly 74%. This change occurred over a two-year period concluding in mid-2025.

The authors described model-based estimates corresponding to 72 strokes, 48 heart attacks, and 38 deaths averted, presenting these as translations from improved control rather than a direct count of observed events.

Operationally, the report described the tool—named the UC Way Hypertension Medication Algorithm—as a stepwise medication approach that can be adjusted for individual factors and special populations. The group began meeting in 2020 and that systemwide implementation occurred in 2023, with the algorithm integrated into UC’s electronic health records.

The report also provided a subgroup figure for Black patients, stating that measured control increased from 63.4% to 67.3%, while noting that disparities remained despite improvement. Looking beyond UC, the report attributed to the authors the view that the approach could be used by other health systems to standardize hypertension care or adapted to other chronic diseases. It also noted that similar efforts were underway at UC for diabetes, presented as an example of how the same approach might be extended within the system.

Key Takeaways:

• The report described an increase in measured blood pressure control from 68.5% to nearly 74% across about 90,000 patients (including patients at UCSF) over a two-year period ending in mid-2025.
• Author-quoted, model-based estimates accompanying the control change included ~4,860 additional people with controlled blood pressure and estimated 72 strokes, 48 heart attacks, and 38 deaths averted.
• The report characterized the program as a multidisciplinary, EHR-integrated algorithm built from meetings beginning in 2020 and implemented systemwide in 2023, with Black-patient control improving while disparities were reported to persist.
