Impact of a dedicated palliative radiation oncology service on the use of single fraction and hypofractionated radiation therapy among patients with bone metastases.

BACKGROUND: Radiation therapy (RT) is frequently used to palliate symptomatic bone metastases. While high quality literature has shown that for uncomplicated bone metastases, shorter radiotherapy courses are just as effective as longer courses for the treatment of pain, shorter courses remain under-utilized. We aimed to assess the impact of a dedicated palliative radiation oncology service on the frequency of single fraction RT (SF-RT) and hypofractionated radiation (hypo-RT) (≤5 fractions) among patients with bone metastases. METHODS: We identified 2,086 instances of palliative radiation (RT) for complicated and uncomplicated bone metastases between April 10, 2008 and September 17, 2014. We used multivariable logistic regression analysis (MVA) to estimate the association of the Supportive and Palliative Radiation Oncology (SPRO) service with the likelihood of receiving SF-RT or hypo-RT after controlling for age, sex, tumor type, and treatment site. RESULTS: Prior to SPRO's implementation on July 1, 2011, the proportion of SF-RT and hypo-RT for bone metastases was 6.4% and 27.6% respectively. After SPRO's implementation, the proportion of SF-RT and hypo-RT increased to 22.3% (P<0.001) and 53.5% (P<0.001) respectively. In MVA, patients were more likely to receive SF-RT [odds ratio (OR) =3.3, 95% confidence interval (CI) =2.4-4.7, P<0.001], and hypo-RT (OR =2.5, 95% CI =2.0-3.1, P<0.001) after SPRO's implementation. Compared to sites without a dedicated palliative service, patients receiving care at the SPRO affiliated department were more likely to receive SF-RT (OR =1.9, 95% CI =1.1-3.2, P=0.02) and hypo-RT (OR =1.5, 95% CI =1.1-2.0, P=0.004) for bone metastases. After SPRO's implementation, the average number of RT courses delivered for bone metastases increased from 17.4 to 25.6 per month, (+8.3, 95% CI =4.99-11.55, P<0.001). Despite greater SF-RT and hypo-RT, the average total fractions per month of palliative RT for bone metastases increased from 163.5 pre-SPRO to 166.8 post-SPRO, though not significantly (+3.22, P=NS). CONCLUSIONS: Implementation of a dedicated palliative radiation oncology service was associated with increased use of SF and hypo-RT and with greater courses of RT delivered for bone metastases.

Radiation oncology resident palliative education.

PURPOSE: Although palliative care is recognized as integral to oncology care, limited data exist regarding the extent to which palliative care training is incorporated into radiation oncology residency training in the United States. We aim to characterize US radiation oncology residents' perceived palliative care educational needs and experience to guide future palliative oncology educational interventions. METHODS AND MATERIALS: An 8-person expert panel developed a survey to assess resident perceptions of generalist palliative care education within radiation oncology residency. Domains of palliative oncology education, derived from national guidelines, included symptom management (pain and non-pain), communication about goals of care, advance care planning, psychosocial issues, cultural considerations, spiritual needs, care coordination, and ethical/legal issues. Residents rated adequacy of their training and their perceived competency in each domain. A total of 433 US radiation oncology residents were identified for participation; 404 completed the survey (response rate, 93%). RESULTS: Residents characterized themselves as "not at all/minimally/somewhat confident" in their ability to take care of patients with palliative care issues in the following domains: symptom management (36% pain, 44% non-pain), communication about goals of care (31%), advance care planning (48%), psychosocial (55%), cultural (22%), spiritual (44%), care coordination (50%), and ethical/legal (50%). On average, 79% of residents rated their training as "not/minimally/somewhat" adequate across all domains. Most (96%) view palliative care as an important competency within radiation oncology and 81% desire more palliative care education. CONCLUSIONS: Although the majority of residents view palliative care as an important competency for radiation oncologists, a majority perceived their educational training as inadequate across multiple domains. Most residents desire further palliative oncology care training. These findings suggest efforts should be made to improve palliative care education during radiation oncology training.
