5. Multivariate logistic regression by the GEE will be used to examine the impact of intervention on improving the extend of congruence between terminally ill cancer patients' preferred and actual EOL care received, and secondary outcomes, namely increasing prognosis awareness, EOL care discussion, and the extent of patient-family agreement on preferences of EOL care, decreasing use of futile aggressive EOL care, and facilitating hospice use and early hospice referral, with simultaneously adjusting for confounding factors. The moderation effects of prognosis awareness, EOL care discussion, and patient-family agreement on preferences of EOL care on extend of congruence between terminally ill cancer patients' preferred and actual EOL care received, decreasing use of futile aggressive EOL care, and facilitating hospice use and early hospice referral between interventional group and the attention controlled group also will be examined in the GEE model.
