In New York, avoidable emergency department (ED) visits—non-emergent care that could be managed in primary care—remain common, with an estimated 40% of ED visits classified as avoidable in 2024. These visits contribute to ED overcrowding, higher costs, workforce strain, and longer wait times that can worsen outcomes for time-sensitive conditions. Barriers to timely primary care, which vary by insurance type, may drive these patterns of avoidable ED use. In this study, we examined the association between insurance type and avoidable ED visits in New York, hypothesizing that such visits are more common among patients with public insurance or who are uninsured than among those with private coverage.
