Check out our latest issue for a roundup of our most recent research and profiles on a few of our newest postdocs. This issue features new findings on opioid tapering programs that show that patients on long-term high-dose opioids who gradually reduced their dose within 3 months faced a lower risk of overdose within a year. It also shares important recent findings that the COVID-19 vaccine does not increase the risk of tinnitus, as well as findings about patterns of breast cancer imaging and Type 2 diabetes remission.
Investigators with the Division of Health Services Research & Implementation Science study how care is delivered, identify opportunities for care improvement, and implement new approaches for organizing and delivering health services. The division brings together scientists with diverse expertise and training, including emergency medicine, epidemiology, health services research, implementation science, internal medicine, nursing, pharmaceutical economics, and pulmonology.
The division co-leads the Care Improvement Research Team, a research team embedded within Kaiser Permanente Southern California’s quality improvement ecosystem. The team works closely with clinical and operational partners at Kaiser Permanente Southern California to identify, prioritize, and solve problems related to quality and affordability. Its goal is to reduce unnecessary practice variation, improve affordability, and transform care.
