Project Description Narrative:


While health care spending has been rising at an unsustainable rate, the quality of health care in the U.S. remains suboptimal. The health care system in Wisconsin has been identified as one of the most expensive systems in the U.S.

Little is known about how best to integrate medical and nonmedical sectors to achieve improved population health and reduce disparities. Furthermore, existing approaches often do not consider the patient perspective in efforts to improve care delivery. Organized, systematic efforts are needed to inform the development and adoption of efficacious, affordable strategies to improve the quality, experience and value of care provided in Wisconsin.

This project aims to create a collaborative of multi-disciplinary experts dedicated to developing, testing and disseminating health care practice, organization and delivery strategies to improve the quality, experience and value of care in Wisconsin.

Project Updates:


  • Engaged in several high-visibility projects, including: Addressing Hospital-based Clostridium Difficile Infection, Evaluation of the Rothman Index, Evaluation of At-Home Nasogastric Feeding in NICU Infants, and Delirium Prevention Partnered with the Froedtert and MCW Office of Population Health (OPH) to implement a bulk outreach message to a subset of patients previously targeted by the outreach team, which led to a 10% increase in Annual Wellness Visit (AWV) scheduling compared to the prior year
  • Worked to better understand and manage the length of stay and resource utilization of patients discharged to skilled nursing facilities following their acute stay at Froedtert Hospital
  • Continued the penicillin de-labeling project, which established a new standard of care in the Pediatric Emergency Department (PED) and presented cost-savings findings at the 2022 Academy of Health Conference and the American Society of Health Economists meeting
  • Continued work related to COVID-19, including delirium prevention interventions among patients hospitalized with COVID-19, racial disparities and COVID-19, child abuse during COVID-19, and COVID-19 remote monitoring with GetWellLoop
