“…Several recent studies 9, 10,11,12,13,14,15,16,17,18 demonstrate that “demand-side” characteristics (e.g., patient race/ethnicity, age, health status, functional decline, prognostic understanding, treatment preferences, nearby and dependent family members, religious views, spiritual support by religious and medical communities, participation in EOL discussions) are highly significant predictors of aggressiveness of EOL care over and above the effects of the hospital or clinic or regional availability of medical resources in which the care was received. Research has shown that these demand-side characteristics explain more of the variance in geographic and ethnic disparities in the aggressiveness of care than do supply-side characteristics (e.g., hospital bed supply, teaching hospital status, number of medical specialists per capita).…”
