Using Propensity Score Matching Techniques to Assess Medicare/Medicaid Service Use

This poster describes the use of a propensity score matching methodology to identify comparison groups among Medicare-Medicaid beneficiaries who received Medicaid-paid LTSS via HCBS waivers versus those who did not receive LTSS. This matching technique was used to establish comparable treatment/control pairs for subsequent analysis of cross-payer effects of providing Medicaid-paid LTSS on Medicare acute care resource use, and could be used more generally to strengthen policy analyses.
