Table 1: Summary of findings from literature review.

Variable AE ADE Utilization Mortality
Age Inconsistent Consistent + Conflicting Consistent +
Gender None Inconsistent Inconsistent Consistent M
Race None NA Inconsistent Consistent AA
SES None NA Consistent - Consistent -
Social Support NA NA Consistent - NA
Comorbidity Inconsistent NA Consistent + Consistent +

Consistent: Most or all studies show a relationship in the same direction between that variable and outcome

+: Positive relationship between variable and outcome (e.g., greater age and higher ADE risk)

-: Negative relationship between variable and outcome (e.g., lower SES and higher health care utilization)

M: Higher risk (e.g., mortality) among males

AA: Higher risk (e.g., mortality) among African Americans

Inconsistent: Some studies show relationship in one direction, others show no relationship

Conflicting: Some studies show relationship in one direction, others show relationship in opposite direction

NA: No studies available for that variable-outcome relationship
