Income-related inequalities and inequities in Irish healthcare utilization.

The aim of this article is to determine the extent of and changes in horizontal inequity in general practitioner and medical specialist utilization in Ireland from 1997 to 2001. Horizontal equity refers to people in equal need of treatment receiving similar treatment regardless of income. After accounting for the differences in the need for such care, this study reports relatively low pro-poor horizontal inequity with respect to general practitioner utilization, increasing slightly between 1997 and 2001. This study finds that a generally pro-rich horizontal inequity distribution in 1997 is replaced by a generally pro-poor distribution in 2001 with respect to medical specialist utilization.
