The Quality Improvement Quick Strike (QIQS) research program provides research networks participating in the Robert Wood Johnson Foundation’s Public Health PBRN Program with supplemental funding and technical assistance to conduct rapid turn-around, time-sensitive research studies that produce evidence about the effectiveness and impact of quality improvement (QI) strategies, public reporting initiatives, and accreditation activities in public health settings. Specifically, the program supports research studies that investigate the effectiveness, cost-effectiveness and/or impact of three related types strategies designed to drive quality in public health practice: (1) QI tools and processes implemented in public health settings; (2) accreditation programs and performance standards implemented in public health settings; and (3) public reporting activities designed to mobilize public health improvement activities, such as the County Health Rankings program and other state-based reporting initiatives.
