Dr. Marsteller is jointly appointed in the Academy of Certified Case Managers and is a member of the Quality Systems Research Group. She specializes in organizational theory and behavior, specifically in estimating the influence of organizational variables on quality improvement activities with a focus on the determinants of successful implementation, dissemination, and sustainability of knowledge. Dr. Marsteller has evaluated infection prevention, safety attitudes and patient safety interventions in the intensive care unit (ICU), cardiac operating room, and other settings. She was a co-principal investigator for a multisite clustered randomized trial of an intervention to reduce central-line associated blood stream infections in ICUs and led research efforts evaluating the effects of leadership, provider engagement and team activities on infections, length of stay and nursing outcome measures.

She presently coaches three states and the District of Columbia in the national “On the CUSP: Stop BSI” project. In addition, she is working with cardiac ORs, ICUs, and floor units to help them implement CUSP and reduce infections. In that effort she will oversee data analysis and work with others to improve cross-unit/area relationships.
