The Impact of Cost Sharing on Emergency Department Use

Abstract: We studied the effect of insurance coverage on the use of emergency department services, using data from a national trial of cost sharing in health insurance. A total of 3973 persons below the age of 62 years were randomly assigned to fee-for-service health insurance plans with coinsurance rates of 0, 25, 50, or 95 per cent, subject to an income-related upper limit on out-of-pocket expenses. Persons with no cost sharing had emergency department expenses that were 42 per cent higher than those for persons on th… Show more

“…These results show more marked reductions in visits due to an increase in co-payments for chronic or non-serious diseases than for emergency or serious diseases. These results were consistent with those of previous studies [9][10][11][12][13][14][15] . The upper limit expenditures of co-payments per month were ≤ 5,000 yen in 67.9% of the subjects with hypertension and 64.1% of those with diabetes mellitus, showing that 5,000 yen is the limit in many insured people.…”

“…Even modest copayments could reduce low-acuity ED visits without reducing emergency visits. [56][57][58] However, to our knowledge, such copayments have not been used for pediatric Medicaid patients. It is worth noting that imposing copayments might reduce overcrowding but might only shift costs instead of reducing them.…”

“…This is an expensive practice that contributes to overcrowding and decreased continuity of care. [7][8][9][10] Evidence suggests that ED overcrowding is associated with adverse clinical outcomes, [10][11][12] and proposed solutions have ranged from streamlining inpatient admissions to expanding primary care. [13][14][15] It is important to understand the current patterns of ED use if primary health care initiatives are to effectively reduce ED workloads and improve overall health.…”
