Inpatient Palliative Care Use Among Critically III Brain Metastasis Patients in the United States

Modifiers of and Disparities in Palliative and Supportive Care Timing and Utilization among Neurosurgical Patients with Malignant Central Nervous System Tumors

Patients with primary or secondary central nervous system (CNS) malignancies benefit from utilization of palliative care (PC) in addition to other supportive services, such as home health and social work. Guidelines propose early initiation of PC for patients with advanced cancers. We analyzed a cohort of privately insured patients with malignant brain or spinal tumors derived from the Optum Clinformatics Datamart Database to investigate health disparities in access to and utilization of supportive services. We introduce a novel construct, "provider patient racial diversity index" (provider pRDI), which is a measure of the proportion of non-white minority patients a provider encounters to approximate a provider's patient demographics and suggest a provider's cultural sensitivity and exposure to diversity. Our analysis demonstrates low rates of PC, home health, and social work services among racial minority patients. Notably, Hispanic patients had low likelihood of engaging with all three categories of supportive services. However, patients who saw providers categorized into high provider pRDI (categories II and III) were increasingly more likely to interface with supportive care services and at an earlier point in their disease courses. This study suggests that prospective studies that examine potential interventions at the provider level, including diversity training, are needed.

Expansion of the LabBM Score: Is the LabPS the Best Tool Predicting Survival in Patients With Brain Metastases?

OBJECTIVES

The objective of this study were to improve the 3-tiered, purely biomarker-based LabBM score, which predicts the survival of patients with brain metastases, by adding the well-established prognostic factor performance status (PS), and to define its role in comparison with the recently proposed Extracranial-Graded Prognostic Assessment score, which is based on the well-known Diagnosis-specific Graded Prognostic Assessment and 2 of the same biomarkers.

MATERIALS AND METHODS

This was a retrospective single-institution analysis of 212 patients, managed with upfront brain irradiation. Survival was stratified by LabBM and LabPS score. Each included serum hemoglobin, platelets, albumin, C-reactive protein, and lactate dehydrogenase (plus PS for the LabPS). Zero, 0.5, or 1 point was assigned and the final point sum calculated. A higher point sum indicates shorter survival.

RESULTS

The new LabPS score predicted overall survival very well (median: 12.1 to 0.7 mo, 1-y rate: 52% to 0%), P=0.0001. However, the group with the poorest prognosis (3 or 3.5 points) was very small (4%). Most patients with comparably short survival had a lower point sum. The LabPS score failed to outperform the recently proposed Extracranial-Graded Prognostic Assessment score.

CONCLUSIONS

Integration of blood biomarkers should be considered when attempting to develop improved scores. Additional research is needed to improve the tools which predict short survival, because many of these patients continue to go undetected with all available scores.
