We compared new Medicaid enrollees with similar ongoing enrollees for evidence of pent-up demand using claims data following Minnesota's 2014 Medicaid expansion. We hypothesized that if new enrollees had pent-up demand, utilization would decline over time as testing and disease management plans are put in place. Consistent with pent-up demand among new enrollees, the probability of an office visit, a new patient office visit, and an emergency department visit declines over time for new enrollees relative to ongoing Medicaid enrollees. The pattern of utilization suggests that the newly insured are connecting with primary care after the 2014 Medicaid expansion and, unlike ongoing Medicaid enrollees; the newly insured have a declining reliance on the emergency department over time.
我们利用明尼苏达州2014年医疗补助扩大后的理赔数据，将新加入医疗补助计划的人员与类似的现有参保人员进行比较，以寻找潜在需求的证据。我们假设，如果新参保人员存在潜在需求，随着检测和疾病管理计划的实施，医疗服务利用率会随着时间推移而下降。与新参保人员存在潜在需求的情况一致，相对于现有医疗补助参保人员，新参保人员进行门诊就诊、新患者门诊就诊和急诊就诊的概率会随着时间推移而下降。医疗服务利用模式表明，2014年医疗补助扩大后，新参保人员正在与初级医疗保健建立联系，并且与现有医疗补助参保人员不同，新参保人员对急诊科的依赖程度会随着时间推移而下降。
