BackgroundHigh out-of-pocket (OOP) cost is a barrier to healthcare access and treatment compliance. Our study examined high OOP healthcare cost and burden trends in adults with kidney disease (KD).MethodsUsing Medical Expenditure Survey 2002-2011 data, we examined the proportion of people greater than 17 years old with KD whose OOP burden was high. Trends by insurance status (private, public or none) and trends by income level (poor, low, middle or high income) were also examined in this study.ResultsApproximately 16% of people with KD faced high OOP burden in 2011. The proportion of adults with high OOP burden between 2002 and 2011 fell by 9.7 percentage points. The proportion of privately insured adults facing high OOP burden decreased by 4.7, those who were publicly insured 22.4, and those who were uninsured, 3.1 percentage points. The proportion of those facing high OOP burden who were poor/near poor fell by 26.5, those who had low income 13.4, and those who had middle income, 9 percentage points.ConclusionsThough high OOP burden declined between 2002 and 2011 in the US population with KD, most of the decline was among the publicly insured, so the uninsured populations with KD remain vulnerable. Providers and policy makers should be aware of the vulnerability of uninsured individuals with KD to high OOP burden.Published by Elsevier Inc.
