Income-based disparities in outcomes for patients with chronic kidney disease

Area of Science:

• Nephrology
• Health Services Research
• Socioeconomic Determinants of Health

Background:

• Understanding the impact of income on end-stage renal disease (ESRD) patient outcomes is crucial, despite reduced financial barriers.
• Socioeconomic status may influence health outcomes for ESRD patients.

Purpose of the Study:

• To examine if low-income ESRD patients experience poorer health outcomes compared to higher-income counterparts.
• To determine if enhanced health insurance can mitigate socioeconomic disparities in ESRD care.

Main Methods:

• Prospective cohort study of 3,165 patients who developed ESRD in the early 1990s.
• Analysis of the association between neighborhood income, insurance status, mortality, and transplant waiting list placement.

Main Results:

• Higher neighborhood income correlated with decreased mortality and increased likelihood of kidney transplant waiting list placement.
• Additional private insurance improved transplant listing rates, especially for low-income patients, but did not affect mortality disparities.
• Low-income ESRD patients face persistent financial barriers to transplantation and higher mortality linked to personal/environmental factors.

Conclusions:

• Greater health benefits can address financial barriers to kidney transplantation for low-income ESRD patients.
• Persistent mortality disparities in ESRD highlight the need to address social, cultural, psychological, and environmental determinants of health.
• Multifaceted interventions are required to improve survival rates for all ESRD patients, irrespective of socioeconomic status.
