In the fourth and final episode of the Quality Improvement (QI) Project Guide series, Drs. Julia Finkelstein and Robert Marcovich join Dr. Andrew Harris, Chair of AUA's Quality Improvement and Patient Safety (QIPS) Committee, for a conversation on acting on the results of and sustaining a QI project. They discuss how to interpret your results of an intervention, decide your next step, and create a realistic plan for sustaining and spreading successful QI interventions.
