Kaiser Permanente Washington researchers are exploring how to improve prevention and treatment of health issues due to alcohol and other drug use. The addictions research group conducts innovative research to help patients and their providers prevent and treat problems caused by alcohol, cannabis, opioids, and other drugs in health settings.
A major focus of the addictions research group is how to integrate patient-centered care for alcohol and other drug use into medical settings. For more than 3 decades, their work has focused on the need for health systems to routinely measure and address alcohol and other drug use as part of whole-person health, in nonjudgmental, patient-centered ways.
"Our alcohol-related research has built tools — such as a brief video, handout, and a patient decision aid — that help overcome stigma so that patients and families can find the help they want and need," said Katharine A. Bradley, MD, MPH, a senior investigator at Kaiser Permanente Washington Health Research Institute (KPWHRI) and internal medicine physician with Washington Permanente Medical Group.
The addictions research group is conducting a variety of studies to improve measures and documentation of substance use in the medical record. "We are working to find ways to easily document the extent of cannabis exposure for both medical and nonmedical use in electronic health records," said Gwen Lapham, PhD, MSW, a KPWHRI assistant investigator. Finding innovative ways to provide treatment is also a focus. "We are testing how to get proven online treatments for addiction into the hands of patients who could benefit," said Joseph E. Glass, PhD, MSW, a KPWHRI associate investigator whose research at the institute is funded in part by an early-career award to study the effectiveness of treatments for alcohol use disorders in primary care.
These are among the group’s current studies:
