Data Transparency Measure:
Hypertension Control
What is hypertension (high blood pressure)?
High blood pressure is a common condition in which the force of the blood against the artery walls is high enough that it may eventually cause health problems, such as heart disease.
Blood pressure is determined by the amount of blood the heart pumps and the amount of resistance to blood flow in the arteries. The more blood a heart pumps and the narrower the arteries, the higher the blood pressure.

Denominator (Universe)
  • Patients 18 through 85 years of age who had a diagnosis of essential hypertension within the first six months of the measurement period or any time prior to the measurement period with a medical visit during the measurement period
  • Note: Include patients who were born on or after January 1, 1932, and on or before December 31, 1998


  • Patients whose blood pressure at the most recent visit is adequately controlled (systolic blood pressure less than 140 mmHg and diastolic blood pressure less than 90 mmHg) during the measurement period


  • Denominator Patients with evidence of end-stage renal disease (ESRD), dialysis, or renal transplant before or during the measurement period
  • Patients with a diagnosis of pregnancy during the measurement period
  • Numerator Not Applicable
Facts about hypertension:
The Centers for Disease Control and Prevention (CDC) reports that:
  • 67 million American adults (31 percent) have high blood pressure—that’s one in every three adults.
  • About half (47 percent) of people with high blood pressure have their condition under control.
  • Hypertension greatly increases the risk for heart disease and stroke, the first and third leading causes of death in the U.S.
  • Almost 30 percent of American adults have prehypertension—blood pressure numbers that are higher than normal, but not yet in the high blood pressure range. Prehypertension raises your risk of developing high blood pressure.
Organizations to Watch - Kaiser Permanente:
In 2000, Kaiser Permanente of Northern California (KPNC) launched an extensive population hypertension management program. By 2009, the percentage of patients with controlled hypertension at KPNC reached a staggering 80 percent - 16 percent higher than the average for California's commercial health patients.  Kaiser Colorado has developed a similar program and, as a result, has also improved the percentage of Kaiser Colorado patients with controlled hypertension (61% in 2008 to 78% by 2010).
How did they do it? The CDC highlights KPNC’s approach to hypertension in the following Field Notes article. Kaiser Permanente’s work on hypertension is one to take to heart as we work towards controlling hypertension in Oregon.
