Disparities in Neuro-Oncology.

PURPOSEOF REVIEW: Health disparities are preventable differences in the diagnosis, treatment, and outcomes of many diseases, including central nervous system (CNS) tumors. This review will summarize and compile the existing literature on health disparities in neuro-oncology and provide directions for future research and interventions. RECENT FINDINGS: Patients from historically marginalized groups are more likely to receive inadequate treatment, develop complications, and experience a shorter life expectancy. Financial toxicity can be particularly severe for patients with CNS tumors due to the high costs of treatment. Additionally, CNS clinical trials and research lack diverse representation.

Assessment of medication management capacity in a predominantly African American and Caribbean American sample of adults with intractable epilepsy.

INTRODUCTION: Suboptimal or partial adherence to antiepileptic drugs (AEDs) is an avoidable cause of seizures and deleterious outcomes in epilepsy. As self-rated adherence may be unreliable, suboptimal adherence may go undetected. This study assessed generalizability of a performance-based measure of medication management to patients with intractable epilepsy. MATERIALS AND METHODS: Participants were 50 adults (age = 42 ±â€¯14 years, 60% female, 82% Black, 20% Hispanic/Latino) with ≥2 seizures in the preceding 6 months. Antiepileptic drug adherence was electronically monitored for one month via Medication Event Monitoring Systems (MEMS) and self-rated (1 = very poor to 6 = excellent). The Medication Management Ability Assessment (MMAA) was administered at follow-up and scored by raters blind to adherence results. Spearman correlations and Poisson regressions assessed their associations. RESULTS: On average, participants self-reported good-to-very good adherence. According to MEMS, participants took AEDs as prescribed 73% of the time; most participants (58%) missed ≥3 doses. The MMAA demonstrated strong internal consistency (Kuder-Richardson 20 = 0.81) and was associated with MEMS: percentage of days doses were taken correctly (rs = 0.29, p = 0.04) and frequency of missed doses (rs = -0.31, p = 0.03). The MMAA was not associated with self-rated adherence. Poisson regressions showed that self-ratings and MMAA performance accounted for unique variance in frequency of missed AED doses. CONCLUSIONS: These findings provide evidence of the MMAA's criterion validity as a measure of capacity to manage AEDs. It may prove useful in cases where suboptimal adherence is suspected but unreported by patients. Its lack of significant association with self-rated adherence is consistent with prior reports; however, future studies should replicate these findings with larger samples.
