Purpose: Most Veterans Health Administration hospitals do not have radiation oncology (RO) departments on-site. The purpose of this study is to determine the impact of on-site RO on referral patterns and timeliness of palliative radiation therapy (PRT).
Materials and methods: A survey was sent to medical directors at 149 Veterans Health Administration centers. Questions evaluated frequency of referral for PRT, timeliness of RO consults and treatment, and barriers to referral for PRT. Chi-square analysis was used to evaluate differences between centers that have on-site RO and centers that refer to outside facilities.
Results: Of 108 respondents, 33 (31%) have on-site RO. Chi-square analysis revealed that RO consult within 1 week is more likely at centers with on-site RO (68% v 31%; P = .01). Centers with on-site RO more frequently deliver PRT for spinal cord compression within 24 hours (94% v 70%; P = .01). Those without on-site RO were more likely to want increased radiation oncologist involvement (64% v 26%; P < .001). Barriers to referral for PRT included patient ability to travel (81%), patient noncompliance (31%), delays in consult and/or treatment (31%), difficulty contacting a radiation oncologist (14%), and concern regarding excessive number of treatments (13%). Respondents with on-site RO less frequently reported delays in consult and/or treatment (6% v 41%; P < .0001) and difficulty contacting a radiation oncologist (0% v 20%; P = .0056) as barriers.
Conclusion: Respondents with on-site RO reported improved communication with radiation oncologists and more timely consultation and treatment initiation. Methods to improve timeliness of PRT for veterans at centers without on-site RO should be considered.
