Impact of Quality Improvement Interventions on the Efficiency of Treatment Planning Timelines in a Modern Proton Therapy Clinic

The interventions identified before data collection were well associated with the evolution of the treatment planning timeline data. When quantifying with control charts, there were noted decreased task completion offset variabilities across many examined tasks. Additionally, the data showed shortened overall planning timelines during the time that the complexity of protons plans was increased, newer delivery approaches were made available, and more complex clinical scenarios were incorporated.
