Objective
Many uninsured patients with end‐stage kidney disease (ESKD) depend upon the emergency department (ED) for hemodialysis (HD). We sought to characterize ED visits for emergent HD by insurance status.
Methods
We performed a cross‐sectional analysis of the 2017 Nationwide Emergency Department Sample, including ED visits by patients ≥18 years old with a length of stay ≤1 day and performance of HD. Insurance status determined by “insured” as Medicare, Medicaid, or commercial and “uninsured” as self‐pay or charity.
Results
Of 118,034,396 adult ED visits, 235,988 were associated with HD: uninsured 62,503 (incidence 5.30 per 10,000, 95% confidence interval [CI]: 5.26–5.34) and insured 172,889 (incidence 14.65 per 10,000, 95% CI: 14.60–14.74). The south census region accounted for 89% of uninsured ED HD (odds ratio [OR] 31.55, 95% CI: 8.97–110.97). Compared to insured patients, uninsured ED HD patients were more likely to be younger (age 18–44, 37.6% vs 19.9%). The most common primary diagnosis for uninsured and insured ED HD patients was hypertensive chronic kidney disease (34.6% and 26.2%, respectively). Uninsured ED HD patients were less likely to be admitted (3.4% vs 36.0%, OR 0.06, 95% CI: 0.02–0.20). Most ED HD patients were discharged home (95.2% uninsured vs 57.6% insured). ED charges per visit were $5,992.32 for uninsured and $10,985.87 for insured ED HD patients.
Conclusions
Our findings highlight the health care burden of ED HD. Novel system approaches are needed for the management of uninsured and insured patients with ESKD.
