Timeliness of Specialty Palliative Care for Veterans With Cancer: An Analysis of Administrative Data
Background
Studies show that early referral to Specialty Palliative Care (SPC) can improve patient- reported outcomes among Veterans with cancer; quality metrics include referral within 8 weeks of an advanced cancer diagnosis. In this study, we explored timeliness of specialty referrals and compared various factors.
Methods
We identified our cohort using Department of Veterans Affairs (VA) Corporate Data Warehouse (CDW). Eligibility criteria included active or history of cancer—using a peer-reviewed, in-house list of ICD-9 and ICD-10 codes—between 2013-2023. We stratified our cohort of Veterans using factors including cancer stage, rurality, and care assessment needs (CAN) scores. We performed survival analyses to look at time to SPC from initial diagnosis and peak CAN score. Predictors of utilization were evaluated using multinomial regression and Cox proportional hazards models through R.
Results
Using CDW’s oncology domain, we identified 475,775 Veterans. 28% received SPC. Most received it near the end of their life as evidenced by the mortality rates (79.5%) in the early period following SPC consultation. Median time to SPC was 515 days. There was a significant difference in utilization rates between urban and rural Veterans (Wilcoxon W-statistic = 2.31E+10, p < 0.001). Peak CAN scores ranged from 0 to 0.81, median peak of 0.057 and interquartile range of 0.1. Multinomial regression model indicated statistically significant associations of advanced cancer (Stages 3 and 4) with timing of SPC. Stage 4 cancer showed the strongest association with receipt of palliative care within 60 days of initial diagnosis (OR 4.8, 95% CI: 4.69-4.93, p < 0.001), suggesting higher stage disease increases the likelihood of palliative care referral and accelerates the timing of these referrals.
Conclusions
We found Veterans received SPC from a broad range of peak CAN scores (0 to 0.81), suggesting that absolute CAN scores may not be clinically actionable indicators but perhaps indicative of changes in condition warranting referral. Stage IV cancer at diagnosis was associated with early SPC. The significant differences in utilization rates between urban and rural patients highlight potential access barriers that should be addressed.
