In recent times, a greater emphasis has been placed on framing patient clinical assessments and QOL as both endpoints and prognostic factors for neuro-oncological care. However, there is currently a lack of consensus on the most effective metrics and instruments for use in patients with primary brain tumors. Due to the heterogeneity in clinical characteristics, histological classification, anatomical location, and available treatment modalities for glioma, quantifying patient clinical condition and QOL within this unique population is particularly challenging. In this paper, we comprehensively review the available literature on the use of clinical assessment tools in glioma patients, highlighting the strengths and limitations of prominent instruments. We demonstrate that clinical outcome assessment (COA) instruments provide valuable and complementary insights into the physical, psychological, and spiritual well-being of glioma patients.

Background: As the population continues to age, the number of adults receiving care for hydrocephalus is expected to increase. Here, we assess trends in the utilization and physician reimbursement for ventriculoperitoneal shunts (VPS), lumboperitoneal shunting (LPS), and endoscopic third ventriculostomy (ETV) for adult hydrocephalus. Methods: The Medicare Part B National Summary Data files from 2000 to 2021 were collected, and information was extracted on procedures performed per year, total charges billed, and actual payments. Linear mixed-model regression analyses were conducted to assess the significance of changes in procedural volume and physician reimbursement over time while adjusting for inflation. Results: Over the period studied, there was a 26% increase in VPS placement (P = 0.11), 11.34% increase in ETV utilization (P < 0.01), and 43.1% decrease in LPS utilization (P < 0.01). This corresponded to annualized changes of + 4.29% for ETV procedures, −8.78% for LPS, and + 45.8% for VPS. There was a statistically significant difference in the change of rate of number of procedures annually between LPS and VPS (P = 0.04). In both inflation-unadjusted and inflation-adjusted analyses, all procedures experienced an annual decline in reimbursement with inflation-adjusted changes of −11.54%/year for ETV, −4.13% for LPS, and −13.12% for VPS. There was a statistically significant difference in the change of rate of reimbursement between LPS procedures and both ETV (P < 0.01) and VPS (P < 0.01). Conclusion: Medicare reimbursement data shows that a commensurate decline in physician reimbursement has accompanied the ongoing rise in adult hydrocephalus procedures.
