Abstract:
56 Background: Palliative radiotherapy (PRT) is a common and effective modality for the relief of symptoms due to malignancy. Members of the supportive care team may be hesitant to refer for PRT due to concerns regarding timeliness of treatment and patient/caregiver time burden. The current structure of most radiation oncology clinics is not conducive to the delivery of timely PRT and few metrics aimed at quality improvement have been reported. Methods: We reviewed all courses of PRT delivered at our institution between January 2017 and December 2018. Hematologic/myeloma primary and postoperative cases were excluded. The dates of referral, consultation, PRT planning simulation, PRT start and end were recorded. An inherent delay was noted if PRT was purposefully delayed (workup, imaging). Time to PRT (TTPRT) was defined as the number of days between referral and start of PRT. A remaining life ratio (RLR) representing TTPRT as a proportion of survival from the time of referral, was developed as a practical metric to represent timeliness of PRT with respect to prognosis. Results: 338 courses of PRT were included from 67% outpatient and 33% inpatient referrals. Indications included pain (55%), neurologic deficits/brain metastases (23%), respiratory symptoms (10%), bleeding (6%) and other (7%). Median TTPRT was 13 d (IQR 4-19), comprised of: referral to consult (3 d), consult to simulation (4 d), and simulation to PRT (6 d). Factors associated with TTPRT included ECOG, PRT indication, site (non-spine bone, chest, or brain), outpatient referral and delay. TTPRT was not associated with age, gender, rural residence, distance to hospital, race, median household income, insurance or marital status. Of 229 patients who died, factors associated with increased RLR were outpatient referral (13% v. 5%), abdomen/pelvis treatment site (16% v. 9%) and delay (17% v. 8%). Conclusions: TTPRT is associated with patient, treatment, and systematic factors, some of which are associated with increased RLR, elucidating several opportunities for improvement. Based on these results, our group has established a dedicated Palliative Radiation Oncology Clinic focused on timely, quality PRT, the outcomes of which will be assessed prospectively.
