A provider-based quality improvement intervention aimed at improving appropriateness of radiation therapy regimens for patients with advanced cancer and painful bone metastases.

Abstract

176 Background: Although guidelines suggest that shorter course radiation treatments for patients with advanced cancer and painful bone metastases are most appropriate, treatment patterns in the United States are inconsistent with this approach. Methods: We implemented a provider-focused intervention at a university-based radiation oncology practice aimed at improving rates of shorter-course radiation treatments for patients with advanced cancer and painful bone metastases. The intervention involved key leaders of the practice participating in a RAND/UCLA Appropriateness Panel to review the latest guidelines and evidence and judge appropriateness of various treatment regimens as it pertained to their practice. These results were compared to current (7/2012-6/2013) practice patterns and presented to the faculty group. This exercise informed a template-based point of care intervention led by a clinical champion and leadership that focused on key aspects of clinical and patient-centered care including whether the bone metastases were complicated or uncomplicated, patient prognosis, extent of disease, and travel distance for the patient to the treatment site. We compared rates of lower burden treatment regimens (less than 10 fractions) for 81 pre-intervention patients with 107 metastases treated between 7/2012-6/2013 and 75 post-intervention patients with 94 metastases treated between 5/2015-1/2016. Results: Overall, painful bone metastases were treated with less than 10 fractions more often in the post-intervention period (38% v. 63%, p < 0.001). Uncomplicated bone metastases treated with conformal radiation were also more likely to be treated with less than 10 fractions in the post intervention period (19% v. 52%, p < 0.001). One quarter of metastases were treated with SBRT during both the pre and post-intervention periods. Conclusions: Leadership support, provider engagement in integrating guidelines into practice, and a note template with point of care clinical reminders can improve rates of appropriate, low-burden radiation oncology treatments for patients with advanced cancer.
