The effect of a subsidy policy on the utilization of community care services under a public long-term care insurance program in rural Japan

Abstract

This cross-sectional study investigated the effect of an interim subsidy policy for low-income beneficiaries to buy home help services under Japanese long-term care insurance (LTCI) for the service utilization of home help and other community care services. Claims records during the period from October to December 2001 were reviewed to compare the monthly amounts for each service and out-of-pocket copayment for subsidized ( n = 137) and non-subsidized ( n = 124) beneficiaries. A multivariable linear regression analysis was conducted to control for age, gender, household size, length of care, and care eligibility level. Compared with the non-subsidized beneficiaries, the subsidized beneficiaries used 1.53 times as much home help service ( p < 0.001), and spent 0.70 times as much on out-of-pocket copayments ( p < 0.001), while they used fewer adult daycare services (0.71 times as much as the non-subsidized did, p = 0.063). The results strongly indicated that the interim subsidy for low-income beneficiaries alleviated the economic burden, but also resulted in service overuse and the substitution of home help services for other community care services. The policy implications of these findings were discussed.
