Our Impact

Results that matter to you,
your family, your world

How many people have benefited from 30-plus years of findings from Kaiser Permanente Washington Health Research Institute (KPWHRI)? That’s hard to say because much of our research helps people avoid health problems. So you won’t find them in doctors’ offices and hospitals. You’ll find them instead at work and at play, unencumbered by serious illness and injury.

But we do know that discoveries from Kaiser Permanente Washington research have changed the way people around the world care for their own health and how health care providers care for their patients.

Here are just a few examples:

Preventing traumatic brain injury

Our early research showed that bicycle helmets reduce head injuries. Within a year, bicycle helmet use accelerated nationwide. We later found that a bike helmet campaign is cost-effective, increases use of helmets, and reduces hospital admissions for head injuries.

Breaking a deadly habit

The phone-based smoking cessation program Kaiser Permanente Washington developed and tested has helped millions across the country to quit tobacco. Behavioral health research in the Kaiser Permanente Washington population established the effectiveness of telephone and web-based counseling to help people quit smoking, a model now used nationwide.

Stopping cancer in its tracks

Research on Kaiser Permanente Washington's risk-based breast cancer screening program—the first of its kind—has set standards and improved the quality and effectiveness of mammography over decades.

Work continues as we seek to identify the best technologies and approaches for finding and treating breast, colorectal, blood, cervical, lung, pancreatic, and other cancers.

In a recent study, KPWHRI showed that Kaiser Permanente Washington doubled colon cancer screening rates while cutting costs by using electronic health records and stepped care to reach out to patients overdue for screening.

Overcoming chronic low back pain

Kaiser Permanente Washington studies of complementary and alternative approaches have influenced national guidelines for treating chronic low back pain. Massage, yoga, and acupuncture are now recognized as sound, low-tech, and relatively inexpensive approaches to this very common health problem.

Getting the care you need

The Chronic Care Model, pioneered and disseminated by KPWHRI’s MacColl Center for Health Care Innovation, is now used by thousands of health care systems worldwide to guide quality improvement efforts for diabetes, asthma, heart disease, and other chronic conditions.

Kaiser Permanente Washington research also proved the power of the patient-centered medical home—a way to coordinate and streamline care in primary care settings. In our studies, the strategy yielded cost savings, lowered death rates, and improved patient outcomes.

Our studies of a model of collaborative care for depression showed that combining psychiatric and primary care results in better patient outcomes and lower costs. Later research showed that effective depression care for patients who also have other chronic conditions such as diabetes and heart disease—an approach called TEAMcare—achieves similar results.

And our study of care for high blood pressure showed that home monitoring combined with a web-based connection to a provider nearly doubles the proportion of patients successfully controlling their condition.

Avoiding the harms of overtreatment

Kaiser Permanente Washington research identified the risks of overprescribing prescription opioids (drugs like Vicodin and Oxycontin) for chronic noncancer pain. It also evaluated the strength of Kaiser Permanente Washington's initiative to improve prescribing safety, proving the effectiveness of standardizing practices through new clinical guidelines and safer monitoring.

Kaiser Permanente Washington scientists also participated in research that revealed increasing harm of overusing high-end imaging such as computed tomography (CT). And they evaluated the effectiveness of Kaiser Permanente Washington's initiative to improve safety by reducing patient radiation doses.

Taking charge of your care—based on your values

Shared decision-making helps people understand the value of their care and make the decisions that are right for them—so they don’t get more or less care than they need. In studying this approach, Kaiser Permanente Washington has delivered more decision aids to patients than has any other single system in the world. So far, our research has shown that Kaiser Permanente Washington's use of video-based decision aids for hip and knee surgery is linked to reduced surgery rates and costs.

Staying sharp as you age

Kaiser Permanente Washington research has shown that seniors who exercise regularly can delay or prevent the onset of dementia. They also have fewer falls and use the health care system less, resulting in lower costs.
