Support and Services at Home (SASH) Evaluation: First Annual Report. 3.4. Participant Characteristics

09/01/2014

Table 2a presents the unweighted demographic and health status characteristics for the SASH program beneficiaries and the two comparison groups. Table 2b presents the propensity weighted averages for the three groups.

TABLE 2a. Unweighted Baseline Demographic Characteristics and Health Status for SASH Participants, Non-SASH/MAPCP Demonstration Beneficiaries, and Non-SASH/Non-MAPCP Demonstration Beneficiaries for July 1, 2010 - June 30, 2011

NOTE: Standardized differences comparing: (1) SASH program beneficiaries to non-SASH/MAPCP Demonstration comparison beneficiaries; and (2) SASH program beneficiaries to non-SASH/non-MAPCP Demonstration comparison beneficiaries that are greater than or equal to 0.10 are noted with an *.

SASH program beneficiaries versus non-SASH/MAPCP Demonstration comparison beneficiaries. Table 2a shows that SASH program beneficiaries were on average slightly older than non-SASH/MAPCP Demonstration comparison beneficiaries (72 vs. 67), more likely to be female, but less likely to be disabled or to receive Medicaid. They were also in poorer health, as measured by the average hierarchical conditions category (HCC) risk score (1.28 vs. 1.18) and Charlson index (1.13 vs. 0.92). Prior to applying the propensity weights there were seven variables with standardized differences greater than 0.10 or less than -0.10 when comparing these two groups. After applying the PS weights (see Table 2b), there were none, indicating that PS weighting is creating a good balance in demographic characteristics and health status between the two groups.

SASH program beneficiaries versus non-SASH/non-MAPCP Demonstration comparison beneficiaries. Table 2a shows that SASH program participants were more likely to be White and on Medicaid than non-SASH/non-MAPCP Demonstration comparison beneficiaries (White: 98% vs. 95%; Medicaid: 68% vs. 55%). Prior to applying PS weighting, these were the only two variables with a standardized differences greater than 0.10 or less than -0.10. After weighting (see Table 2b), there were no covariates with standardized differences that exceeded these boundaries, again indicating that PS weighting is creating a good balance in demographic characteristics and health status between the two groups.
