Background: ASCO recommends that late-stage and/or recurrent disease patients with a prognosis of 6-24 months receive specialty palliative care within eight weeks of diagnosis. Prior studies suggest only 30% of eligible patients are referred to outpatient palliative care. Little is known about existing referral patterns to direct quality improvement initiatives. Our aim was to characterize outpatient palliative care referral sources, timeliness, and completion rates across our cancer center. More broadly, this investigation may serve as a model for outpatient palliative care utilization improvement at other cancer centers. Methods: A single institution retrospective quality improvement study was conducted of patients in the seven oncology subspecialties with the most palliative care referrals from 2019 – 2022. Data collected included demographics, referral source, and utilization metrics. Outcomes were rate of referral completion and time from referral to first palliative care visit, hospice enrollment, and/or death. Descriptive statistics were performed. Results: 1671 outpatient specialty palliative care referrals were placed. 57% were initiated by medical oncologists, 21% by inpatient palliative care consulting service at hospital discharge, and 14% by surgical oncology. 27% of referred patients did not schedule an appointment. Gynecologic and breast cancer patients had the highest rates of being scheduled. Median time from referral to appointment was 20 days (interquartile range 9 – 30 days). Reasons patients did not utilize palliative care included transition to hospice (41%), lack of interest (41%), or death prior to visit (7%). 79% of patients seen by palliative care who died were enrolled in hospice. Median time from palliative care referral to hospice enrollment was 66 days (IQR 22 – 164 days), and median time from hospice enrollment to death was 13 days (IQR 5 – 31 days). Conclusions: In a single institution self-evaluation, most patients referred to outpatient specialty palliative care completed referral within thirty days. Within the context of this institution, relevant goals for quality improvement interventions include increasing palliative care referrals among surgical oncologists and shifting palliative care referrals earlier in the disease course and prior to need for inpatient hospital admission. Understanding the elements of the creation of our palliative care referral database and relevant data tracking may serve as a method for other institutions to target interventions that may improve uptake of outpatient palliative care referrals at cancer centers more broadly.
