Kaiser Permanente Washington Health Research Institute (KPWHRI) covers many fields, but much of what we do is health services research. That means we’re studying what really works — and what doesn't — in health care, with a focus on achieving aims including better population health, improved patient experience, and lower health care costs.
It all starts with Kaiser Permanente Washington’s learning health system, where research and practice work side by side to inform and improve each other. Researchers benefit from Kaiser Permanente Washington’s comprehensive capture of rich information about patients’ health, use of health care, and costs. Clinical leaders benefit from rigorous evaluations of novel innovations in care delivery and provider reimbursement.
“Together, we are learning what it takes to quickly translate what works into our health system — and track the long-term effects on outcomes that matter to patients, clinicians, and policymakers,” said David Arterburn, MD, MPH, a senior investigator. Here are just a few examples:
The impact of our health services research is extensive. Being part of the Kaiser Permanente system, along with our membership in the Health Care Systems Research Network, the Breast Cancer Surveillance Consortium, and other national and international collaborations increases the size and diversity of our study populations. These connections also help KPWHRI shape care and policy beyond the Kaiser Permanente Washington system.
