UCSF Study Finds Simplified Systems Intervention Improves Blood Pressure Control in Safety-Net Settings

A recent estimate from the Centers for Disease Control reports that high blood pressure—and the many conditions associated with it—contributes to over 400,000 deaths and costs the nation more than $40 billion each year.

Patients can avoid poor health effects by lowering blood pressure with medication and diet, but more than half of all Americans with hypertension don’t have the condition under control.  A few integrated healthcare systems, such as Kaiser Permanente Northern California, have achieved control rates as high as 90 percent in their patients, but this approach has been considered out of reach for the many low-income and minority patients who rely on less well-resourced safety-net settings for care.

Now, a new study led by UC San Francisco researchers, partnering with clinical leaders in the San Francisco Department of Public Health, shows that a simplified intervention building on the hypertension treatment algorithm used in Kaiser Permanente’s Preventing Heart Attacks and Strokes Every Day (PHASE) program can significantly improve rates of blood pressure control in the city’s safety net clinics.
