From “bench” to bedside: science-based alarm management with high IMPActS

In my upcoming presentation at the Human Factors in Healthcare Symposium (March 21-23, 2022 in New Orleans, LA), Dr. Michael Rayo will walk through the contributions of our alarm research and design work made possible through our P30 grant awarded from the Agency for Healthcare Research and Quality. Dr. Rayo will step through the relevant science that was applied, the research and design process that was used, the relevant findings, and our current and future directions. Dr. Rayo will also discuss the successes and failures of each of our related interventions through the lens of the IMPActS framework, which can also be used as a design and implementation planning tool to anticipate potential barriers and facilitators (Fitzgerald, 2019).
