Community-living Medicare beneficiaries ages 65+ who survive 12 months and continuously enrolled in traditional Medicare (n= 3716).

^†

Household=laundry, shopping, meals, bills/banking; Mobility=indoor & outdoor, transferring from bed; Self-care=eating, dressing, bathing, toileting.

^‡

Group differences for those with disability who did and did not report negative consequences due to insufficient help with household activities (n= 1,195 versus 243), mobility (n=894 versus 321), and self-care (n=775 versus 206).

^§

Models adjust for older adults’ age, gender, race, supplemental payer, self-rated health, dementia status, number of chronic conditions.

Estimates reflect the adjusted difference in Medicare spending associated with each characteristic at the specified spending quantile. Positive values reflect higher spending and negative values reflect lower spending while confidence intervals that overlap zero reflect differences that are not statistically significant. 95% confidence intervals based on standard errors clustered at the primary sampling unit to account for the NHATS design.
