Financial Toxicity in Diabetes: The State of What We Know

Abstract

Purpose of Review: This systematic examination quantifies financial toxicity- the economic burden and related financial distress experienced by patients due to medical costs- in diabetes management globally, analyzing prevalence, mechanisms, and interventions across diverse healthcare systems and geographic contexts. Recent Findings: Data indicates 30–60% of diabetes patients experience financial toxicity, with household expenditures ranging from 5 to 40% of income on disease management, and demographic disparities evident. Current intervention strategies demonstrate limited efficacy, particularly in resource-constrained settings, while policy approaches show mixed results across economic contexts. Summary: Financial toxicity operates through four identified pathways: direct expenses, indirect costs (productivity/caregiver burden), insurance coverage limitations, and structural access barriers. Research priorities include developing validated measurement instruments for diabetes financial toxicity, implementing contextually appropriate interventions, and establishing causative relationships between financial burden and clinical outcomes through longitudinal studies.
