Abstract: Cost-sharing is a health care cost-containment technique in which health care services are partially paid for by patients out of pocket. Costsharing can reduce non-cost-effective care, but it can also undermine the financial protection and access values of health insurance. We review the empirical evidence published since the mid-1980s about cost-sharing's effect on utilization, expenditures, health, and adverse consequences, including how the effects vary by form of care, by health status, and by sociodemogra… Show more

“…19 Again, these findings are consistent with international evidence. 20,21 Gap payments and PBS co-payments impact most significantly on the poor -those who are most likely to suffer ill health in the first place. [5][6][7][8]22 The empirical evidence evaluating the effect of co-payment on healthcare demand clearly identifies that individuals with lower incomes reduce their use of healthcare services to a greater extent in response to increased copayments.…”

Evidence on the effect of cost-sharing for nonemergency outpatient utilization is more mixed (Cherkin, Grothaus, and Wagner, 1989; Remler outpatient utilization is more mixed (Cherkin, Grothaus, and Wagner, 1989;Remler and Greene, 2009). and Greene, 2009).…”
