Trends and Outcomes of Early and Late Palliative Care Consultation for Adult Glioblastoma Patients: A SEER-Medicare Retrospective Study
Abstract PurposeGlioblastoma (GBM) carries a poor prognosis despite standard of care. Early palliative care (PC) has been shown to enhance survival and quality of life while reducing healthcare costs for other cancers. No study has investigated differences in PC timing on GBM patient outcomes.MethodsThis study used Surveillance, Epidemiology and End Results (SEER)-Medicare data from 1997-2016. Based on ICD codes, three groups were defined: (1) early PC within 10 weeks of diagnosis, (2) late PC, and (3) no PC. Outcomes were compared between the three groups.ResultsOut of 10,812 GBM patients, 1,648 (15.24%) patients had PC consultation with an overall positive trend over time. There were no significant differences in patient characteristics. There were significant differences in survival among the three groups (P<0.001), with early PC patients with the lowest mean time to death from diagnosis (3.99 ± 4.22 months). The early PC group had significantly lower overall cost of home health aid (1901 ± 3025, p<0.0001) and overall healthcare costs (82842 ± 52726, p<0.0001) compared to other groups. Conclusion We present the first investigation of PC consultation prevalence and outcomes, stratified by early versus late timing, for adult GBM patients. Despite an overall increase in PC consultations, only a minority of GBM patients receive PC. Patients with late PC had the longest survival times. Early PC was associated with lower healthcare costs and resource utilization when accounting for the patients’ entire disease course. Prospective studies can provide additional valuable information about this unique population of GBM patients.
