Changing practice patterns for breast cancer radiation therapy with clinical pathways: An analysis of hypofractionation in a large, integrated cancer center network

We found that our implementation of clinical pathways substantially increased adoption of HF-WBI for breast cancer. We found no significant change in utilization of HF-WBI among community physicians following publication of a seminal trial for HF-WBI until after clinical pathway implementation, which increased the use of HF-WBI by 20-fold. Clinical pathways may be effective in changing practice patterns, disseminating evidence, and realizing health care savings.
