SPOTLIGHT: 20 Years of Measuring and Improvement: Controlling High Blood Pressure

As WCHQ celebrates its 20th anniversary, we review the results achieved over that time. In celebration of American Heart Month, we examine Blood Pressure (Hypertension) Control.

Blood Pressure Control was among the very first measures WCHQ publicly reported, due to its prevalent role in mortality and preventability. In 2021, the CDC found that hypertension was a primary or contributing cause of 691,095 deaths and is associated with more than $131 billion annually.

Since we began our work on improving hypertension, WCHQ members have seen dramatic improvement. In 2005, WCHQ members achieved 59.8% blood pressure control in a population of and increased to 82.8% control for 506,969 patients in 2015. From 2015 through 2019, WCHQ members maintained a control rate near or above 84% while continuing to see increasing volumes of patients with hypertension (658,650 patients in 2019). The dedication WCHQ members have shown towards this measure have resulted in control rates that exceed the national averages by 12% - 49%.

Like most measures, blood pressure control was impacted by the COVID-19 pandemic. For those still able to report data during 2020, WCHQ members saw blood pressure control rates dip to under 80% (reporting for 582,863 patients). Today, much like the early years of the measure, the control rate for WCHQ members is back on an upward trend. In June of 2023, 82.7% of 559,327 patients with hypertension were in good control.

In an effort to help members look at blood pressure control through different lenses, WCHQ measures blood pressure control for patients with diabetes, patients with Ischemic Vascular Disease (IVD), and most recently for patients with obesity. WCHQ members perform slightly better on the blood pressure control measures for patients with diabetes, obesity, or IVD than on the general blood pressure control measure for all patients with hypertension, consistently achieving at least 84% in good blood pressure control for the more specialized measures.
